Energisektorn står idag för en tredjedel av de globala växthusgasutsläppen och på senare tid har tillgången på energi blivit en alltmer kritisk fråga då energisystemets utveckling har en avgörande roll för att nå nationella och internationella klimatmål. Energipolitiska styrmedel reglerar bland annat att företag och energisystemets utveckling går i rätt riktning och på grund av att många faktorer behöver inkluderas är energipolitiken ett komplext arbete. Tidigare studier visar att flertalet energipolitiska styrmedel har varit effektiva i syfte att minska klimatpåverkan från industriella verksamheter. Att som företag vara uppdaterad på förändringar inom energimarknaden och utvecklingen av energipolitiska styrmedel har kommit att bli viktigt då de påverkar verksamhetens energianvändning. Den svenska industrisektorn är en central användare av energi, där massa- och pappersindustrin står för omkring hälften av den totala energianvändningen inom Sveriges industrisektor. Energi är en integrerad fråga i massa- och pappersindustrin med utmaningar gällande miljöpåverkan, resursutnyttjande och hantering av förändrade energipriser. Ökad energieffektivitet för energiintensiva industrier är dessutom en viktig del i den globala klimatomställningen. Att integrera energimanagement i verksamheten är ett verktyg för att genomföra energieffektiviseringsåtgärder. Tidigare forskning och modeller för implementering av energimanagement i industriella verksamheter inkluderar däremot inte energirelaterad omvärldsbevakning, vilket skapar utrymme för vidare forskning. Denna studie syftar till att genom en omvärldsbevakning identifiera hur nuvarande och framtida energipolitiska styrmedel påverkar kemiska massa- och pappersbruk, med avseende på el som energibärare. Vidare undersöks hur förändringar på elmarknaden kan komma att påverka den kemiska massa- och pappersindustrin. Resultatet analyseras med utgångspunkt från ett befintligt ramverk för strategiskt arbete med energimanagement. Avslutningsvis appliceras ett företagsperspektiv genom en fallstudie på ett företag inom den kemiska massa- och pappersindustrin, för att undersöka interna strategier för energirelaterad omvärldsbevakning. Studien har genomförts med en kvalitativ metod samt med ett deduktivt angreppssett genom främst litteratur- och intervjustudier. Resultatet visar att flertalet styrmedel påverkar massa- och pappersindustrin idag och att majoriteten av dessa även väntas göra det i framtiden. Pågående förhandlingar inom Fit for 55, där ett antal direktiv väntas justeras och förhandlas om, kommer medföra effekter på industrin. Vad gäller elsystemets förändringar kan elpriset komma att bli mer varierande, både under dygnet men även under året, vilket grundas i en kombination av ökad elektrifiering och implementering av fler intermittenta energikällor i elsystemet. För att hantera dessa förändringar kan massa- och pappersindustrin se möjligheter i att bidra till en minskad energianvändning, exempelvis genom att delta på flexibilitetsmarknaden. Den befintliga teoribildningen kring energimangagement är inte fullständig då tidigare forskning saknar omvärldsperspektiv. Ett utökat ramverk för energimanagement har därför tagits fram där omvärldsbevakning integreras som ytterligare nyckelkategori. Vidare presenteras en modell som illustrerar ansvarsfördelnig för energirelaterad omvärldsbevakning sett ur ett perspektiv där företag, branschorganisationer och EU inkluderas. Avslutningsvis visar studien att elintensiva företag bör formulera tydliga interna strategier för hur energirelaterad omvärldsbevakning ska inkluderas i energimanagement. / Today, the energy sector accounts for a third of the global greenhouse gas emissions. The supply of energy has recently become an increasingly critical issue as the development of the energy system plays a crucial role to achieve national and international climate goals. Energy policy instruments regulate the development of companies' energy use and the energy system, but since several factors need to be included the field of energy policies is complex. Previous research shows that energy policy instruments have been effective to reduce the climate impact of industrial activities. Due to the constant development of the energy market and modifications of energy policy instruments, enterprises need to stay updated on these changes as they affect the business's energy use. The Swedish industrial sector is a central user of energy, where the pulp and paper industry accounts for about half of the total use of Sweden's industrial sector. Therefore, energy is an integrated issue in the pulp and paper industry with current challenges in terms of environmental impact, resource utilization, and changing energy prices. Increased energy efficiency in energy-intensive industries is important for confronting climate changes and energy management is a tool for implementing energy efficiency measures. However, current energy management literature and models for implementation in industrial firms do not include energy-related external environmental monitoring, which enables further research. The aim of this study is by conducting an external environmental analysis, identify how current and future energy policies affect the chemical pulp and paper industry, concerning electricity as an energy carrier. Furthermore, the study also seeks to investigate how changes within the electricity market affect the chemical pulp and paper industry. The results are analyzed based on an existing conceptual framework of energy management. Finally, an organizational perspective is applied to a company in the chemical pulp and paper industry to examine internal strategies for energy-related external environmental monitoring. The study is based on a qualitative research method with a focus on a deductive approach. The results show that serveral policy instruments affect the pulp and paper industry today, and the majority of these are also expected to do so in the future. Ongoing negotiations within Fit for 55, where several directives are expected to be adjusted, will have effects on the industry. Regarding the changes in the electricity network, the price of electricity expects to become more variable, both during the day but also during the year, which is based on a combination of increased electricity use and implementation of intermittent energy sources. To deal with these changes, the pulp and paper industry can see opportunities in contributing to a reduction in energy use, for example by participating in the flexibility market. The existing studies in the field of energy management are not complete as previous research lacks an external perspective. An expanded framework for energy management has been developed, where external monitoring is integrated as an additional key category in an existing model. Moreover, this study presents a model illustrating the distribution of responsibilities for energy-related environmental monitoring, seen from a perspective that includes companies, industry associations, and the EU. To conclude, this study shows that electricity-intensive organizations should formulate internal strategies for how energy-related external environmental monitoring should be implemented and included in energy management.

Mercury contamination is an environmental issue with high priority due to its high toxicity. In addition to the atmospheric deposition, several lakes and rivers in Sweden are contaminated as a result from wood and pulp-fiber industries which stretches back 200 years. In Luleå, Sweden, a former groundwood industry, Karlshäll, has contributed to mercury pollution in the sediments of Notviken, a small bay connected to Luleå River and the Bothnian Sea, through release of process water. Industrial release of chemicals and wood pulp have resulted in a special type of sediment called fiber banks. The fiber banks contain high levels of organic matter and very little oxygen which contributes to large gas emissions from the fiber banks, gas ebullition. There is no generally accepted method for examining how mercury contaminants are spread through gas ebullition. The aim of this thesis was to review and find methods for that purpose. Through the literature review several types of methods emerged. Some of them were useful for measuring volumes of gas, whereas others were better designed for collecting gas and analysing it for concentration of elements. There are pros and cons with all methods but the one considered most useful in the case of Karlshäll would be Skarp’s method with active and passive sampling. The passive part includes setting up tents over the fiber bank with a known area, and then calculate the volumes of gas which migrate up through the water during a certain amount of time. The active sampling consists of stirring the fiber bank sediment with a stick and then gather the ascending gas bubbles in a Teflon-bag. The Teflon bag is thereafter sent to a chemical environmental laboratory for analysis of the concentration of elements. This method is the only one of the ones reviewed in this thesis which have been tested in Sweden at sites with gas- ebullition facilitated mercury transport. Although, Varadharajan et al’s (2011) sampling device with automation could be applicable if a long-term, high frequency monitoring programme would be used at Karlshäll. In addition, a sampling device with an integrated carbon-absorption-tube collector for trapping gaseous Hg would be beneficial if the samples can’t handle a long-distance transportation. Thus, the samples could be sent to a local laboratory instead. However, this type of device is not yet invented and would need further studies to develop. / Kvicksilverföroreningar är ett stort miljöproblem som räknas till de särskilt farliga ämnena vilka skall fasas ut för att nå miljömålet giftfri miljö. Föroreningarna är mycket giftiga för djur och miljö och det kvicksilver som redan spridits ansamlas och stannar kvar under lång tid i mark, vatten och biota. Utöver den atmosfäriska depositionen så är floder, älvar och sjöar i Sverige förorenade med kvicksilver, ett resultat av en 200-årig industri för tillverkning av pappersmassa och träfiber där kvicksilver varit en del i tillverkningsprocessen.  I Luleå fanns det ett träsliperi kallat Karlshäll mellan åren 1912–1962 som släppte ut orenat processvatten innehållandes kvicksilver tillsammans med rester av träfiber till den närliggande viken, Notviken, som är ett inlopp från Lule älv. Industriella utsläpp av kemikalier och träfiber har resulterat i bildandet av en viss typ av bottensediment, kallad fiberbank. Fiberbankarna innehåller höga nivåer av organiskt material i kombination med lite syre vilket bidrar till stora gasutsläpp från fiberbankarna, gasavgång. Det finns ingen vedertagen metod för att undersöka hur kvicksilverföroreningarna sprids genom gasavgång. Syftet med denna uppsats är att undersöka och hitta metoder som kan undersöka kvicksilverföroreningarnas spridning via gasavgång. Genom en litteraturstudie och intervju med en entreprenör inom miljöteknik framträdde flertalet olika metoder för att kunna kvantifiera eller mäta kvicksilver i gas från fiberbankar. Några av dem var användbara för att mäta volymer av gas. Andra metoder lämpade sig bättre för att samla in gas för analys av koncentrationer av olika ämnen.  Även om alla metoder i viss mån lämpar sig för att undersöka gasavgång från sediment ansågs Jonny Skarps metod som inkluderade både aktiv och passiv provtagning med gasfällor och teflonpåsar vara den mest passande för fiberbankar likt den i Karlshäll. Den passiva metoden innefattar installation av tält över en känd area på sedimentbotten och sen beräkna mängden gas som bubblar upp under en viss tid. Den aktiva insamlingsmetoden bygger på att sediment störs med ett spetsigt föremål, exempelvis ett lod, så att gasbubblor släpper från sedimentet och samlas in med hjälp av en teflon- påse. Teflon-påsen skickas sedan till ett kemiskt laboratorium i Göteborg för analys av innehållet i gasen. Båda dessa provtagningssätt kunde tillsammans mäta mängden kvicksilver ifrån gasen samt volymen av gasen. Denna metod är den enda av de som undersökts i denna uppsats som testats i Sverige på platser med kvicksilver som avgått i gasform från fiberbankar. Dock så är Varadharajan med fleras (2011) automatiserade gas-insamlare ett bra alternativ ifall en hög frekvens av provtagning är nödvändig i kombination med en lång insamlingstid. Denna skulle kunna kombineras med en insamlingsmetod av gasbubblor där det lokala kemilaboratoriet kan analysera innehållet. I detta fall krävs att ett kolfiber-rör är en del av mätinstrumentet. Dock finns det ännu inte något sådant instrument och fler studier behövs för att utveckla ett sådant.

With the introduction of a fourth industrial revolution, new technologies are changing the behaviour of buyers in all markets. Coupled with an acceleration caused by the COVID-19 pandemic, manufacturers are now more than ever facing a pressure to digitally transform. These digital transformations entail not only the implementation of new technologies, but also require change in every part of the organisation. The purpose of this thesis is to investigate the role that digital transformation and technological advancements has on B2B sales. Moreover, the thesis aims at creating recommendations for managers to strategically address these transformations as well as providing empirical data on digital transformation. To achieve the purpose and aim of the thesis, an exploratory single case study was performed on one of Europe’s largest paper manufacturers. The case study includes a semi-systematic literature review of 108 research articles, as well as 12 interviews with various employees from the case organisation. The findings of the case study were three-fold. Firstly, combining the areas covered by literature with the findings from the case study, a proposed framework for how technology affects the entire B2B sales organisation is created. This framework consists of the four dimensions: technology, value chain, business model and internal aspects. Secondly, based on the current level of digitalisation in the case company, 15 specific measures for improving the level of digitalisation and enabling digital transformation are presented. Lastly, the study revealed that the challenges an organisation faces when aiming at achieving a digital transformation are not only related to the organisation’s current level of digitalisation but also reliant on it’s customers, product sell and the market in which it operates. / Med introduktionen av en fjärde industriell revolution förändrar nya teknologier beteendet av köpare på alla marknader. Med en ökad acceleration av digitalisering kopplat till covid-19 pandemin står tillverkare inför ett större tryck än någonsin att digitalisera. De digitala transformationerna innebär inte bara nya teknologier utan kräver också förändring i hela organisationen. Syftet med denna uppsats är att undersöka rollen digital transformation och teknologisk utveckling har för en B2B försäljningsorganisation. Dessutom syftar uppsatsen till att skapa rekommendationer för ansvariga för att strategiskt hantera dessa transformationer samt förse empirisk data på digitala transformationer. För att uppfylla syftet och målet med uppsatsen utförs en explorativ fallstudie på en av Europas största papperstillverkare. Fallstudien inkluderas en semi-systematisk litteraturstudie bestående av 108 forskningsartiklar, samt 12 intervjuer med anställda inom organisationen i fallstudien. Resultatet av fallstudien var trefaldigt. För det första, genom att kombinera litteraturen med insikterna från fallstudien skapades ett föreslaget ramverk för hur teknologi påverkar en hel B2B försäljningsorganisation. Ramverket består av fyra dimensioner: teknologi, värdekedja, affärsmodell ,och interna aspekter. För det andra, baserat på den nuvarande nivån av digitalisering i organisationen i fallstudien presenteras 15 specifika medel för att förbättra nivån av digitalisering och göra digital transformation möjligt. Till sist, visar studien på hur utmaningarna en organisation möter när de försöker digitaliseras är inte enbart relaterade till organisationens nuvarande nivå av digitalisering, utan beror också på organisationens kunder, produkter, och marknaden de har sin verksamhet i.

This qualitative case study focuses on investigating the benefits and challenges when applying Radio frequency identification (RFID) for identity tracking of products at manufacturing companies in the paper industry. This study has been designed from qualitative methods such as interviews and observations at the case company. A case study was chosen as it was considered most appropriate to answer the study’s purpose and questions. In the theoretical frame of reference, advantages, challenges, and limitations regarding the application of RFID technology in manufacturing companies emerge. In summary, there are several advantages to the application of RFID technology, including economic, technological, safety, and efficiency, for example improved traceability and reduced manual handling. The limitations and challenges that emerged during the theory are also financial, security, technological, and economic. The limitations focus on the technology itself while the challenges focus on the application of the technology. The results show that RFID technology offers advantages such as increased efficiency and accuracy in unloading and inventory, improved traceability, reduced risk of manual errors, and reduced mental stress. The challenges include the risk of technical errors, the need for security measures for information sharing, and issues regarding standardization and frequency regulation. There are solutions to some challenges, such as optimization of tag reading and collaboration with external parties. However, complex security issues and the need for standardization for a smooth transition to RFID technology remain. The study was limited to the application of RFID technology in the paper industry from packing out to the customer. During the study interesting information has emerged that has not been investigated further, partly because there was no room for further research, and it extended outside the scope of the study. This resulted in suggestions for further research, it would be interesting, among other things, to investigate the possibility of placing the reader in the gates of the magazines to see what advantages this gives or to investigate the possibility of attaching the RFID tag at an earlier stage of the production line. / Denna kvalitativa fallstudie har utförts på ett fallföretag och fokuserar på att undersöka fördelar och utmaningar vid en applicering av radiofrekvensidentifiering (RFID) för identitetsföljning av produkter hos företag inom pappersindustrin. Detta arbete har utformats från kvalitativa metoder som intervjuer och observationer på fallföretaget.  En fallstudie valdes då det ansågs mest lämpligt för att besvara arbetets syfte och frågeställningar. I den teoretiska referensramen framkommer fördelar, utmaningar och begränsningar gällande applicering av RFID-teknologin i tillverkande företag. Sammanfattningsvis finns det flera fördelar med applicering av RFID-teknologi, bland annat ekonomiska, teknologiska, säkerhetsmässiga och effektivitetsmässiga, exempelvis förbättrad spårbarhet och minskad manuell hantering. De begränsningar och utmaningar som framkommit under teorin är också ekonomiska, säkerhetsmässiga, teknologiska och ekonomiska. Begränsningarna fokuserar på själva tekniken medan utmaningarna fokuserar på appliceringen av teknologin. Resultatet visade att RFID erbjuder fördelar såsom ökad effektivitet och noggrannhet i utlastning och inventering, förbättrad spårbarhet, minskad risk för manuella fel samt minskad mental påfrestning. Utmaningarna inkluderar risk för tekniska fel, behov av säkerhetsåtgärder för informationsdelning samt frågor kring standardisering och frekvensreglering. Det finns lösningar på en del utmaningar, såsom optimering av taggavläsning och samarbete med externa parter. Dock kvarstår komplexa säkerhetsfrågor och behovet av standardisering för en smidig övergång till RFID-teknologi. Arbetet avgränsades till appliceringen av RFID-teknologin inom pappersindustrin från packning till kund. Under arbetet har det framkommit intressant information som inte har undersökts vidare, bland annat på grund av att det inte fanns utrymme att forskas vidare på och att det sträckte sig utanför avgränsningen för arbetet. Detta resulterade i förslag till vidare forskning, det hade bland annat varit intressant att undersöka möjligheten att placera läsaren i portarna på magasinen för att se vilka fördelar detta ger eller att undersöka möjligheten att fästa RFID-taggen i ett tidigare skede av produktionslinjen.

Submitted in fulfilment of the requirements of the Master of Technology degree in Cost and Management Accounting, Department of Management Accounting, Durban University of Technology, Durban, South Africa, 2015. / Environmental degeneration, market pressures and stricter regulation and waste legislation has placed organizations under tremendous pressure to change their current processes and adopt cleaner production (CP) techniques and technologies. However, in countries like South Africa, CP implementation still remains low. In light of this problem, the government has made efforts to promote CP among industries by forming a support structure called the RECP (resource efficient cleaner production), as a strategy to encourage organizations to embrace this change and move away from the tradition end-of-pipe technologies towards CP technologies. This study is based on a case study of a paper manufacturing company in Kwadakuza, KwaZulu-Natal. The aim of this study was to use Environmental Management Accounting (EMA) to identify benefits of CP. Paper manufacturing consumes large amounts of natural resources and generates excessive wastes. Hence, the operational activities of paper mills have a negative environmental impact. However, the scope of this study was limited to the steam generation process and focused mainly on the efficiency of the current coal-fired boilers used in the boiler plant. The research methodology used in the study was both quantitative and qualitative involving triangulation. Data was collected by means of a questionnaire, semi-structured interviews and documentary review. The company uses old, obsolete boilers to generate steam. It had been discovered during a cleaner production assessment (CPA) of the process that the process uses large amounts of coal and generates excessive boiler ash (waste). This boiler ash also contains approximately 20 percent unburned coal present resulting in major losses to the company. Furthermore, the company has also experienced regular breakdowns during the year resulting in loss in production and high maintenance costs. Hence, it was concluded that the steam generation process was inefficient and that the boilers were not operating as per technological specification. However, management was unaware of the huge losses incurred due to raw material losses, more especially the coal used in the process. Environmental costs were also inaccurately calculated and thus underestimated. Hence, the ‘true environmental’ costs were not considered during strategic decision making. Over the last two decades, EMA has emerged as an important approach by organizations wanting to improve their environmental and economic performances. However, despite the many pilot projects conducted that demonstrated the positive impact that EMA has on an organization, EMA implementation remains slow and lagging in South Africa. EMA is an environmental management tool that traces environmental costs directly to the processes and products that are responsible for those costs, thereby highlighting problem areas that need to be prioritized when considering the adoption of CP. The literature review on the role and impact of implementing EMA and the benefits of adopting CP was presented to determine and outline views and findings of past researchers. Previous researchers identified that traditional costing systems did not adequately account for the actual environmental costs incurred by companies as much of these costs were hidden under overhead accounts. Hence, production costs were high, resulting in incorrect profit margins being set and ultimately impacting on company profitability. The main cause of this was that non-product output costs were added to production cost instead of being separately recorded as ‘non-product’ output. These costs are actually environmental costs as they represent waste. Material Flow Cost Accounting (MFCA), a tool of EMA, was considered as an appropriate method to implement to accurately calculate non-product output costs. MFCA made managers aware of the true magnitude of their losses and inefficiencies of current technology by increasing the transparency of non-product output costs (environmental costs). MFCA was further used to benchmark non-product output costs against technological standards and best available technological standards to highlight the economic and environmental benefits of adopting CP techniques and technologies. Based on the findings, one recommendation is that the company should consider restructuring their conventional costing system and adopt an EMA system instead. The use of an MFCA model had been suggested. This model was used by the Economy, Trade and Tourism industry in Japan to identify non-product output and improve efficiency of production processes. In addition, findings revealed that the company should implement CP techniques in the short-term to ensure that boilers are functioning according to technological specification. This will result in economic and environmental benefits for the company. However, greater savings potential is available in the long-term, by changing current technology and adopting state-of-the-art technologies. This would, however, require greater investment needs of the company to taken into consideration during strategic decision making.

Mature industries have played and still play a crucial role in national and world economies. To survive and retain competitiveness, they need to innovate, as innovation is the driver of economics growth and industrial transformation. However, existing research does not provide sufficient explanation of how innovation in mature industries can be enabled based on resources and internal development logic of those industries, i.e. endogenously. Some previous studies focused on incremental innovation patterns, which led to an underestimation of innovation potential of mature industries. Other studies acknowledged a high innovation potential of mature industries, but failed to explain how, through what mechanisms, industry-endogenous logic can bring about major innovations. Therefore, the purpose of this thesis is to systematically address, explain and conceptualize endogenous industry- innovation and its driving mechanisms in mature industries. To achieve this purpose, three main issues are addressed. First, the thesis investigates and conceptualizes the notion of industry endogenous innovation mechanisms based on the path dependency theory. Second, the thesis addresses strategic choices and actions by established companies that are rooted in the industry endogenous mechanisms and result in highly innovative outcomes. Third, the thesis systematically analyses different aspects of radicalness of innovations resulting from industry endogenous mechanisms. The thesis represents a qualitative, embedded case study with two main industry cases, i.e. the global lighting industry and the Swedish pulp and paper industry. The lighting industry and its sub-cases in the form of specific lighting technologies have been studied via the analysis of patents of leading lighting manufacturers, archival and secondary data sources as well as interviews with different types of actors in the industry. The pulp and paper industry and its sub-cases in the form of innovation initiatives have been studied with the help of interviews with leading manufacturers and research institutes, as well the analysis of annual reports and secondary data sources. The outcomes of the study are presented in the form of the thesis cover paper and five appended papers. The results show that innovations of any magnitude can be endogenously developed in mature industries. At the industry level, endogenous innovation is driven by innovation mechanisms that can be conceptualized as reactive sequences and self-reinforcing mechanisms. At the level of individual companies, the exploitation strategy corresponds to the logic of endogenous innovation mechanisms by enabling highly innovative outcomes and building on a wide range of resources available in the industry. The endogenous character of innovation mechanisms imposes certain limitations on the radicalness of the outcomes in the form of trade-offs in terms of how many and what particular aspects can be radically new at once. With these results, the thesis contributes to a more balanced overall understanding of innovation potential of mature industries and allows shifting the focus of discussion from whether mature industries can develop radical innovation to when and under what conditions they can succeed in this process. The results of the thesis also suggest several recommendations for managers in established companies with regard to how they can they can take advantage of industry endogenous innovation mechanisms. / Mogna branscher har traditionellt sett spelat och spelar fortfarande en viktig roll för såväl nationella ekonomier som för världsekonomin. För att överleva och behålla sin konkurrenskraft behöver mogna branscher fortsätta vara innovativa, eftersom innovation driver ekonomisk tillväxt. Även för enskilda, etablerade företag i sådana branscher är innovation centralt – de företag som inte lyckas med innovation riskerar att förlora i konkurrensen och bli ersatta av andra. Det finns emellertid än så länge inte någon bra förklaring till hur innovation i mogna branscher kan möjliggöras endogent, d v s baserat på befintliga resurser och branschens interna utvecklingslogik. Tidigare studier har antingen tenderat att underskatta innovationspotentialen i mogna branscher eller misslyckats med att visa hur – d v s genom vilka mekanismer – branschens egen logik kan möjliggöra radikala innovationer. Syftet med denna avhandling är att förklara och konceptualisera endogena innovation och dess drivmekanismer i mogna branscher. För att uppnå detta syfte undersöker avhandlingen endogena innovationsprocesser på såväl bransch- som företagsnivå samt analyserar i vilken utsträckning olika aspekter av radikala innovationer möjliggörs av endogena mekanismer. Avhandlingen är baserad på kvalitativa fallstudier av två branscher. Den första branschen är den globala belysningsindustrin, där olika belysningstekniker har studerats via analyser av patent, sekundära datakällor samt intervjuer med olika typer av aktörer i branschen. Den andra branschen är svensk pappersmassaindustri, där ett antal olika innovationsinitiativ har studerats framförallt med hjälp av intervjuer med ledande företag och forskningsinstitut. Avhandlingen består av en kappa och fem bifogade artiklar. Resultaten visar att alla typer av innovationer, inklusive radikala innovationer, kan utvecklas endogent i mogna branscher. På industrinivån drivs denna utveckling av innovationsmekanismer i form av reaktiva sekvenser och självförstärkande mekanismer. På företagsnivån kan processen drivas av en innovationsstrategi som bygger på exploatering av befintliga resurser. Trots att alla aspekter av radikala innovationer kan utvecklas endogent, medför endogena mekanismer emellertid vissa begränsningar i form av kritiska avvägningar när det gäller hur många och vilka aspekter som kan hållas radikala samtidigt. Med dessa resultat bidrar avhandlingen till en mer balanserad, övergripande förståelse för innovationspotentialen i mogna branscher och medger ett skifte av fokus i vetenskapliga diskussioner från frågan om mogna branscher kan utveckla radikala innovationer till när och under vilka villkor de kan lyckas med denna process. I avhandlingen ges även rekommendationer för ledare i etablerade företag med avseende på hur de kan dra nytta av branschens endogena innovationsmekanismer.

O grande volume de resíduos sólidos industriais gerado pelo setor de celulose e papel e o alto custo do seu manejo estimulam pesquisas em busca de soluções mais adequadas para o seu gerenciamento. Uma alternativa que se destaca neste contexto é o aproveitamento destes resíduos em materiais de construção. Este trabalho visa o aproveitamento do lodo de ETE de indústria de papel na produção de compósitos cimentícios para uso na construção civil. Foi estudada a influência de diferentes teores da adição do lodo de ETE (5%,10%,20% e 30% em massa) em argamassa de cimento e areia, com relação água-cimento de 0,65. Determinou-se para o resíduo: teor de umidade; massa unitária; massa específica; pH; sazonalidade de geração e teor de sólidos fixos e para o compósito: massa específica aparente; absorção de água por imersão; absorção de água por capilaridade; retratibilidade; isolamento acústico; resistência à compressão e análise da microestrutura. O resíduo foi classificado como Classe II – A, não inerte e não perigoso, o que indica alto potencial para aproveitamento em materiais de construção. Sua incorporação na argamassa aumentou a absorção de água por capilaridade em 12,76 % e por imersão em 18,93% no traço com 30% de resíduo para a empresa "A". Houve também a diminuição da resistência à compressão com a incorporação do resíduo, entretanto definiu-se o ponto-ótimo de incorporação em 12% para as duas empresas avaliadas, garantindo assim a resistência mínima à compressão de 2,5 MPa, exigência para blocos sem função estrutural. A incorporação de resíduo também apresentou decréscimo na massa específica do compósito de 14% na empresa "A" e de 34% para a empresa "B" para os traços de 30% de resíduo. Os resultados permitem concluir que este compósito é adequado para uso em materiais de construção sem função estrutural. / The large volume of industrial solids residues generated by the pulp and paper sectors and its high management cost stimulate research aiming at finding adequate solutions to its management. An alternative that shows high potential in this context is using these residues in building materials. This work aims at studying the use of paper's mills effluent treatment solid waste in the production of cement composites to be used in construction. The influence of adding different sludge proportions (5%,10%,20% and 30% in mass) in cement and sand mortar, with a water-cement relation of 0,65 was studied. The humidity ratio, unit mass, specific mass, pH, generation season and fixed solid concentration for the residue; and specific apparent mass, water absorption by immersion, water absorption by capillarity, acoustic isolation, compression resistance and microstructure analysis for the composite. The residue was classifies as Class II – A, not inert and not dangerous, which indicated high potential for use as building materials. Its use in the mortar increased the water absorption by capillarity in 12.76% and in immersion by 18.93% in the trace of 30% residue from company "A". There was also a decrease in compression strength when the residue was incorporated, however the optimal incorporation point was defined in 12% for both evaluated firms, guaranteeing the minimum compression resistance of 2.5 MPa, required for block without structural function. The residue incorporation also presented a decrease in the composite specific mass of 34% for company "B" and 1% for company "A" for the traces of 30% residue. The results allow us to conclude that this composite is adequate for use as building materials with no structural function.

The values of corrosion rates were compared with the BM, ZTA and WM corrosion rates in electrolytic solutions of the main chemical components of the industrial white liquor in the same temperature range. These solutions were 0,1 mol/L of Na2SO4; 2.276 mol/L of NaOH; 0.126 mol/L of Na2S; 0.128 mol/L of Na2CO3 and simulated white liquor composed of the above solutions with the same molar concentrations. The BM to 24°C, industrial white liquor aerated presented corrosion rate of 0.022 mm/year, 0.045 mm/year for the HAZ and 0.032 mm/year for the WM. It was observed that the HAZ corrosion rates were higher than BM and WM in all solutions studied. Lower corrosion rates were in Na2CO3, followed by NaOH, Na2S, simulated white liquor and finally with the highest corrosion rates in white liquor industry. All solutions are presented alkaline, except sodium sulfate, and it was observed that the three regions are passivated when compared to a reference solution of 0.1 mol/L Na2SO4, and aerated with a pH between 6.0 to 6.5. This passivation film are complex chemical composition due to the presence in solution of OH- HS- ion. From the corrosion potentials of BM in each solution and the pH values it was found that the BM region is passivated according iron Pourbaix diagram in water. Chronoamperometry and voltammetric studies showed that these passivation films that promote greater protection against corrosion, they are solubilized in NaOH solution, simulated white liquor and industrial white liquor when submitted to anodic polarization in potential near at +2.0 V versus saturated calomel electrode. In Na2S and Na2CO3 solution was observed the formation of thick deposits on the surface of BM and when analyzed by EDS was observed the presence of phases such as oxides, sulfides and possibly iron carbonate. / Este trabalho tem como objetivo o estudo eletroquímico do aço ASTM A285 Grau C soldados com eletrodo revestido AWS E 7018 em meio de licor branco industrial empregado na indústria de papel e celulose pelo método Kraft. As amostras foram retiradas por eletroerosão em três regiões: metal base (MB), região termicamente afetada pela soldagem (ZTA) e pelo metal de solda (MS). As taxas de corrosão das três regiões metálicas foram determinadas em temperaturas de 8°C a 60°C. Os valores das taxas de corrosão foram comparados com as taxas de corrosão do MB, ZTA e MS em soluções eletrolíticas dos principais componentes químicos do licor branco industrial, no mesmo intervalo de temperatura. Estas soluções foram de 0,1 mol/L de Na2SO4; 2,276 mol/L de NaOH; 0,126 mol/L de Na2S; 0,128 mol/L de Na2CO3 e em um licor branco simulado composto pelas soluções acima com as mesmas concentrações molares. O MB, a 24°C, em licor branco industrial, aerado, apresentou taxa de corrosão de 0,022 mm/ano, 0,045 mm/ano para a ZTA e 0,032 mm/ano par o MS. Observou-se que as taxas de corrosão da ZTA foram superior a do MB e MS em todas as soluções estudadas. As taxas de corrosão mais baixas foram em Na2CO3, seguido pela solução de NaOH, Na2S, licor branco simulado e finalmente, com as maiores taxas de corrosão, em licor branco industrial. Todas as soluções apresentaram-se alcalinas, exceto a de sulfato de sódio, e constatou-se que as três regiões encontravam-se passivadas quando comparada a uma solução de referência de 0,1 mol/L de Na2SO4,aerada e com pH entre 6,0 a 6,5. Estes filmes de passivação são de composição química complexa devido a presença em solução de íon OH- e HS-. A partir dos potenciais de corrosão do MB em cada solução e dos valores do pH foi verificado que a região do MB encontra-se passivado segundo o diagrama de Pourbaix de ferro em água. Estudos voltamétricos e de cronoamperometria mostraram que estes filmes de passivação, que promovem uma maior proteção contra a corrosão, são solubilizados em meio de NaOH, licor branco simulado e no licor branco industrial quando submetidos a polarizações anódicas em potenciais próximos de +2,0 V versus eletrodo de calomelano saturado. Em solução de Na2S e Na2CO3 foi observado à formação de depósitos espessos sobre a superfície do MB e quando analisados por EDS, observou-se a presença de fases como de óxidos, sulfetos e possivelmente carbonato de ferro.

O setor industrial produtor de papel e celulose tem aumentado sua relevância comercial nas últimas décadas devido à demanda constantemente crescente. O aumento na competitividade do setor gerado pela economia globalizada e a dificuldade de desenvolvimento de bons planos de produção em ambientes produtivos cada vez mais complexos têm motivado a pesquisa por novas e efetivas ferramentas de auxílio à tomada de decisão. Considerando estas dificuldades, abordamos neste trabalho o problema de dimensionamento e sequenciamento de lotes com foco em empresas com processo integrado de produção de celulose e de papel. Trata-se de um problema de planejamento de médio a curto prazo, geralmente com maior enfoque no curto prazo por considerar o planejamento detalhado da produção em horizontes de planejamento que não superam 30 dias. No processo integrado de celulose e papel, foram consideradas as decisões de produção do digestor, evaporador, caldeira de recuperação e de múltiplas máquinas produtoras de papel, além do controle de estoque de produtos intermediários e finais. Modelos matemáticos da literatura foram modificados e estendidos para incorporar características adicionais do problema como, por exemplo, processos com múltiplas máquinas de papel. Além disso, foram desenvolvidas heurísticas construtivas, heurísticas de melhoria, abordagens de solução híbridas baseadas em algoritmos genéticos combinadas com ferramentas comerciais de solução exata, além de combinações entre os métodos. As abordagens desenvolvidas foram testadas computacionalmente e as melhores combinações de métodos foram definidas. De forma geral, os resultados dessas abordagens foram superiores aos obtidos por ferramentas de solução comerciais puras. Ademais, a variação proposta da heurística de melhoria fixe-e-otimize com mudanças na função objetivo se destacou com relação aos demais métodos, obtendo os melhores resultados, independentemente da qualidade da solução inicial utilizada. As principais contribuições desta tese são a apresentação de modelos matemáticos para representar apropriadamente o problema estudado, e o desenvolvimento de métodos de solução efetivos para resolver o problema. / The pulp and paper industry has been increasing the commercial importance in recent decades due to the constant growing demand. The increasing competitiveness of this sector generated by the globalized economy and the difficulty to develop good production plans in complex production environments have motivated the search for new and effective decision support systems. Given these difficulties, in this thesis we address the lot sizing and scheduling problem focused on integrated pulp and paper mills. This is a problem of medium to short term planning, generally more focused on the short term as it covers detailed production schedules in planning horizons which do not exceed 30 days. In these integrated pulp and paper process the production decisions of digester, evaporator, recovery boiler and multiple paper machines are considered, apart from the inventory control of intermediate and final products. Mathematical models known in the literature were modified and extended to incorporate additional features of the problem, such as processes with multiple paper machines. In addition, constructive and improvement heuristics, and hybrid methods based on genetic algorithms combined with a commercial solver were developed, as well as combinations of these solution approaches. The methods developed were computationally tested and the best combinations of methods were defined. Overall, the results of these methods were superior to the solutions obtained by pure commercial solvers. Moreover, the alternative variation proposed of the improvement heuristic fix-and-optimize with exchanges in the objective function surpassed the other methods, obtaining the best results, regardless of the quality of the initial solution used. The main contribution of this thesis are the presentation of mathematical models that appropriately represents the problem under study, and the development of effective solution methods to deal with the problem.
