Electricity availability and the costs thereof in South Africa were traditionally considered an abundant and low cost commodity, but in recent years this situation has changed altogether. Industries are challenged by a strained national electricity grid and tariff increases more than four times the national inflation rate over the past two years, with further tariff increases expected in subsequent years; thus, exposing industries to significant business risks that may jeopardise the sustainability of industries. With the majority of the national electricity supply derived from coal, South Africa's push to reduce carbon emissions exerts even more pressure on industries as electricity usage is inextricably linked to its carbon footprint. In addition, South Africa's reliance on cogeneration from industries for its 2010 - 2030 electricity capacity plan further promotes industries to become more self–sufficient concerning electricity generation. In view of the above, there is a need in the South African integrated iron and steel industry for a framework that collectively addresses the governing factors pertaining to electricity generation in this industry, technical and economical quantification of available technologies and implementation of these technologies. This dissertation researches the current driving/governing and the remediating factors to become more self–sufficient in terms of electricity generation. A framework for electricity generation opportunities in the integrated iron and steel industry is developed from the literature study and the researcher's own experience. The framework embodies four building blocks into a single and all–encompassing framework, which provides the necessary governing factors that quantify the potential need to pursue electricity generation/cogeneration, the technical and economical implications and, inevitably, the implementation requirements and guidelines. Validating the framework against case studies pertaining to ArcelorMittal Newcastle realised a correlation of between 84.6% to 97.6% concerning the technical parameters. In addition, the validation process also indicated that the framework is aligned with current practices applied by ArcelorMittal South Africa. The framework will enable South African integrated iron and steel industries to expand and adapt their own procedures to be specific to their operational requirements. The implementation of the framework should be tailored to address the specific needs concerning cogeneration in industry. / Thesis (M.Ing.

The results using disaggregated panel data suggest the existence of an aggregation bias in the estimation using aggregated data, and these bias would underestimate the price elasticity of the steel sector. In order to compare the relations between the price elasticities of long and short term, dynamic heterogeneous panel were estimated by Mean Group and Pooled Mean Group estimators. It’s important to highlight that, according to the author knowledge, this is the first study to use panel data estimation for demand price elasticity to steel products in Brazil, in a manner to control for the heterogeneity across different steel products. / Essa dissertação apresenta estimativas para a elasticidade-preço da demanda por aço no Brasil, a partir de dados agregados e desagregados da indústria siderúrgica. Os resultados das estimativas a partir do painel com dados desagregados sugerem que existe um viés de agregação nas estimativas já realizadas a partir de dados agregados, e esse viés subestimaria a elasticidade-preço do setor siderúrgico. Com a finalidade de comparar as relações entre as elasticidades-preços de curto e longo prazo foram estimados painéis heterogêneos dinâmicos, através de estimadores Mean Group (MG) e Pooled Mean Group (PMG). É importante ressaltar que, de acordo com o conhecimento do autor, este é o primeiro estudo a usar estimação em painel para estimação da elasticidade-preço da demanda por produtos siderúrgicos no Brasil, dessa forma, controlando a estimativa pela heterogeneidade entre os tipos de aço.

SMF är viktiga för den svenska finansmarknaden då de utgör 99 % av de totala företagen i landet. Dessa företag anses vara mycket bankberoende och mer känsliga för externa ekonomiska fluktuationer än större företag. Oavsett hur den globala ekonomin ser ut så måste företag kunna finansiera sin verksamhet med kapital. Kapitalstruktur är ett omdebatteratforskningsämne som saknar en generell teori för majoriteten av företag, vilket skapar en stor forskningsyta för ämnet. Sverige har en omfattande export med en finansmarknad som är väl integrerad med den globala ekonomin. Den svenska exporten föll avsevärt under finanskrisen 2008 vilket ger en indikation om att exportberoende företag drabbades hårt av finanskrisen,inte minst SMF. Ett minskat kreditutbud i kombination med en finansiell kris kan förmodas ha gett upphov till finansieringsproblem för dessa företag.Syftet med uppsatsen är att undersöka sambandet mellan företagsspecifika faktorer och kapitalstrukturen i metallbranschens företag, där den primära aspekten för studien är att utreda hur företagens kapitalstruktur förändrades i samband med finanskrisen 2008.Studien utgår från en kvantitativ metod med en deduktiv ansats. För att besvara studiens syfte och forskningsfrågor genomförs regressions-, korrelations- och deskriptiva analyser för att kunna analysera sambandet mellan de utvalda beroende variablerna och de oberoende variablerna. Flertalet regressionsanalyser och ANOVA-tester genomförs för att kunnaundersöka om en signifikant skillnad i företagens kapitalstruktur föreligger mellan tidsperioderna. Resultatet visar att det finns en signifikant skillnad i de utvalda företagens kapitalstruktur mellan perioden under finanskrisen och efter krisen. De kortfristiga skulderna stod för den största förändringen som minskade markant under krisperioden i metallbranschens företag. De oberoende variablerna som påvisar det största sambandet förskuldsättningsgraden är lönsamhet och materiella anläggningstillgångar. Studien finner ett negativt samband mellan lönsamhet och samtliga skuldsättningsgrader, samt ett negativt samband mellan materiella anläggningstillgångar och den långfristiga skuldsättningsgraden.Ett motsatt förhållande observeras dock för den kortfristiga skuldsättningsgraden som enligt resultatet har ett negativt samband med materiella anläggningstillgångar. Studien finner även ett mindre positivt samband mellan tillväxt och samtliga skuldsättningsgrader. / SMEs have become significantly important for the Swedish economy since they account for 99 % of all the businesses in Sweden. These firms rely heavily on bank credits and are more sensitive to external economic fluctuations relative to larger firms. Regardless of the events in the global economy, firms must be able to finance its operations with capital. Previousresearch on capital structure indicates a difficulty to find a general theory that can be applied for the majority of firms, which provides more scope for further research in the subject. Sweden is a very export-dependent country and is highly integrated into the global economy. The Swedish export decreased substantially due to the financial crisis 2008, which indicates that export-dependent firms was suffering during the given time period. The combination of a decline in credit supply and a financial crisis gives us the assumption of financial problems in these firms. The purpose of this study is to examine whether or not the recent financial crisis had an impact capital structure in the iron- and steel industry. The importance of different determinants that affects the capital structure will also be reviewed.A quantitative method with a deductive approach will be used for the study. To fulfil the purpose of the study, regression-, correlation- and descriptive analysis will be performed in order to analyse the relation between the dependent variables and the independent variables. Several regression analysis and ANOVA-test will be carried out in order to determine whether or not there is a significant difference in the firms capital structure between the two time periods. The study finds a significant change in capital structure between the two time periods. The short-term debt ratio accounted for the greatest change and decreased substantially during the financial crisis. In addition, the result suggests that profitability and tangible assets are the most important determinants explaining the capital structure of Swedish SMEs in the iron- and steel industry. The study finds a negative relation betweenprofitability and leverage, and a negative relation between tangible assets and short-term debt. Contradictory, a positive relation can be observed between tangible assets and long-term debt. Additionally, a small positive relation can be found between growth and leverage during both time periods. / <p>Betyg B, 170612</p>

This thesis investigates manufacturer-distributor power relationship in the Chinese Iron and Steel Industry. The main objectives of this study are to identify, describe and investigate the power relationships in Chinese Iron and Steel Industry; to understand the concept of power from the perspective of distributors and their relationship with State-Owned Enterprises and Private-Owned Enterprises in this industry; and to explore the possibility of developing an extended research power-relationship framework by investigating the power construct and potentially related and relevant factors in the Chinese market that may impact predicted outcomes such as positive conflict resolution attitude and levels of conflict. Two quantitative pilot studies were conducted, consisting of 14 surveys with semi-structured questions each, which were instrumental in the design of an extended power relationship model by incorporating the factors such as the level of trust, frequency of communication and level of guanxi that drive positive conflict resolution attitude into the traditional power model that had not been combined in a single framework before. Subsequently, the main study was carried out comprising 148 questionnaires completed by distributor firm managers. These represent the views of 74 respondents, who responded for both state-owned enterprises and private-owned enterprises in the Chinese Iron and Steel Industry The sample size is 74 respondents including 14 respondents that were also respondents for the pilot studies. This study generated four main findings. 1) a State-Owned Enterprises tend to use more non-coercive power than Private-Owned Enterprises, and have a stronger negative effect than Private-Owned Enterprises; 2) although Private-Owned Enterprises were rated higher than State-Owned Enterprises in the level of trust, and have a stronger positive effect when explaining the observed relationship between the level of trust and positive conflict resolution attitude, the difference is really minimal; 3) Private-Owned Enterprises were rated higher than State-Owned Enterprises in the frequency of communication, and have a stronger positive effect than State-Owned Enterprises in the explanation of the relationship between frequency of communication and positive conflict resolution attitude. 4) Private-Owned Enterprises were rated higher than State-Owned Enterprises in the level of guanxi, and have stronger positive effect than State-Owned Enterprises in the explanation of the relationship between level of guanxi and positive conflict resolution attitude. These findings contribute to fill gaps in the literature with regard to power relationships in distribution channels. This thesis extends the current boundary of knowledge through the formulation of an extended framework that integrates conflict resolution constructs into a typical/traditional power model. This extended framework comprises new constructs such as level of trust, frequency of communication and level of guanxi and hypothesises their impact on conflict resolution attitude and level of conflict in the Chinese distribution channel. New knowledge is created by investigating differences regarding the use of power by SOEs and POEs considered from the distributor perspective in the Chinese context. Theoretical and managerial implications are discussed in detail.

This thesis is an investigation of whether an energy efficiency obligation scheme would be cost-effective for the Swedish industrial sector. The basic guidelines of the scheme were constructed based on the characteristics proposed in the Energy Efficiency Directive and the previously implemented schemes in other EU Member States. In order to measure the cost effectiveness of the scheme for the industries, a Cost Benefit Analysis was performed. The results of the study show that the participation of the industries in an energy efficiency obligation scheme seems to be cost effective, and the Benefit to Cost Ratios of the analysis where ranging in numbers higher than one, showing that the benefits outweigh the costs. The scheme is in general more cost effective when scenarios assuming high policy intensity for the whole economy of the country are used as input for the calculation of the BCRs, which are also affected positively when higher fuel prices scenarios are adopted. The obligation should be placed upon the distributors, since the prices of energy distribution are administratively regulated. There is opportunity of financial benefits for the Swedish industries from agreements of energy savings delivery to the distributors in order for them to fulfill their obligation. These benefits will support the cost recovery of the investments for the energy savings measures. The possibility of certificate trading in the context of the scheme is another option that can create opportunities for financial gains and stimulate further the energy market. Basing the costs inputs from other EU Member States offers an insight on how these costs could be formed in the case of Sweden, but they cannot be taken as a complete calculation of the scheme’s financial effects. As a result, this study does not offer a final conclusion on the cost-effectiveness of the scheme; it rather serves as a means of support of the final conclusion regarding the cost-effectiveness of energy efficiency obligation schemes for the Swedish industries.

IPCC reported in its climate change report 2013 that the atmospheric concentrations of the greenhouse gases (GHG) carbon dioxide (CO2), methane, and nitrous oxide now have reached the highest levels in the past 800,000 years. CO2 concentration has increased by 40% since pre-industrial times and the primary source is fossil fuel combustion. It is vital to reduce anthropogenic emissions of GHGs in order to combat climate change. Industry accounts for 20% of global anthropogenic CO2 emissions and the iron and steel industry accounts for 30% of industrial emissions. The iron and steel industry is at date highly dependent on fossil fuels and electricity. Energy efficiency measures and substitution of fossil fuels with renewable energy would make an important contribution to the efforts to reduce emissions of GHGs. This thesis studies energy efficiency measures and fuel substitution in the iron and steel industry and focuses on recovery and utilisation of excess energy and substitution of fossil fuels with biomass. Energy systems analysis has been used to investigate how changes in the iron and steel industry’s energy system would affect the steel plant’s economy and global CO2 emissions. The thesis also studies energy management practices in the Swedish iron and steel industry with the focus on how energy managers think about why energy efficiency measures are implemented or why they are not implemented. In-depth interviews with energy managers at eleven Swedish steel plants were conducted to analyse energy management practices. In order to show some of the large untapped heat flows in industry, excess heat recovery potential in the industrial sector in Gävleborg County in Sweden was analysed. Under the assumptions made in this thesis, the recovery output would be more than three times higher if the excess heat is used in a district heating system than if electricity is generated. An economic evaluation was performed for three electricity generation technologies for the conversion of low-temperature industrial excess heat. The results show that electricity generation with organic Rankine cycles and phase change material engines could be profitable, but that thermoelectric generation of electricity from low-temperature industrial excess heat would not be profitable at the present stage of technology development. With regard to fossil fuels substituted with biomass, there are opportunities to substitute fossil coal with charcoal in the blast furnace and to substitute liquefied petroleum gas (LPG) with bio-syngas or bio synthetic natural gas (bio-SNG) as fuel in the steel industry’s reheating furnaces. However, in the energy market scenarios studied, substituting LPG with bio-SNG as fuel in reheating furnaces at the studied scrap-based steel plant would not be profitable without economic policy support. The development of the energy market is shown to play a vital role for the outcome of how different measures would affect global CO2 emissions. Results from the interviews show that Swedish steel companies regard improved energy efficiency as important. However, the majority of the interviewed energy managers only worked part-time with energy issues and they experienced that lack of time often was a barrier for successful energy management. More efforts could also be put into engaging and educating employees in order to introduce a common practice of improving energy efficiency at the company. / Halterna av växthusgaserna koldioxid (CO2), metan och kväveoxider har under de senaste 800 000 åren aldrig varit högre i atmosfären än vad de är idag. Detta resultat redovisades i IPCCs klimatrapport år 2013. CO2-koncentrationen har ökat med 40 % sedan förindustriell tid och denna ökning beror till största delen på förbränning av fossila bränslen. Ökade koncentrationer av växthusgaser leder till högre global medeltemperatur vilket i sin tur resulterar i klimatförändringar.  För att bromsa klimatförändringarna är det viktigt att vi arbetar för att minska utsläppen av växthusgaser. Industrin står för 20 % av de globala utsläppen av CO2 och järn- och stålindustrin står för 30 % av industrins utsläpp. Järn- och stålindustrin är i dag till stor del beroende av fossila bränslen och el för sin energiförsörjning. Energieffektiviseringsåtgärder och byte av fossila bränslen mot förnybar energi i järn- och stålindustrin skulle kunna bidra till minskade utsläpp av växthusgaser. Denna avhandling studerar åtgärder för effektivare energianvändning och möjligheter för bränslebyte i järn- och stålindustrin. Avhandlingen fokuserar på återvinning och utnyttjande av överskottsenergier och ersättning av fossila bränslen med biomassa. Energisystemanalys har använts för att undersöka hur förändringar i järn- och stålindustrins energisystem skulle påverka ekonomin och de globala utsläppen av CO2. Avhandlingen studerar också betydelsen av energiledning och nätverkande för att uppnå en effektivare energianvändning. Fokus har här varit på att studera hur energiansvariga resonerar kring varför energieffektiviseringsåtgärder genomförs eller varför de inte genomförs. Djupintervjuer med energiansvariga vid elva svenska stålverk genomfördes för att analysera denna fråga. För att ge ett exempel på den stora outnyttjade potentialen av överskottsvärme från industrin analyserades potentialen i Gävleborgs län. Möjligheterna att använda överskottsvärmen som fjärrvärme eller för att producera el analyserades. Här visar resultaten att fjärrvärmeproduktionen skulle bli mer än tre gånger så stor som elproduktionen. En ekonomisk utvärdering gjordes där tre tekniker för produktion av el från lågtempererad industriell överskottsvärme jämfördes. Resultaten visar att elproduktion med organisk Rankine-cykel eller en så kallad fasändringsmaterialmotor kan vara lönsam, men att termoelektrisk elproduktion inte är lönsam med dagens teknik och prisnivåer. Det är möjligt att ersätta en del av det fossila kolet i masugnen med träkol och på detta sätt introducera förnybar energi i stålindustrin. Man kan också ersätta gasol som används som bränsle i stålindustrins värmningsugnar med syntesgas eller syntetisk naturgas (SNG) som produceras genom förgasning av biomassa. Under de antaganden som gjorts i avhandlingen skulle det dock inte vara lönsamt för det skrotbaserade stålverk som studerats att ersätta gasolen med bio-SNG. För att uppnå lönsamhet behövs i detta fall ekonomiska styrmedel. Hur olika åtgärder påverkar de globala utsläppen av CO2 beror till stor del på hur framtidens energimarknad ser ut. Elproduktion från industriell överskottsvärme skulle minska de globala CO2-utsläppen i alla scenarier som studerats, men för de andra åtgärderna varierar resultaten beroende på vilka antaganden som gjorts. Resultaten från intervjustudien visar att svensk stålindustri anser att energifrågan är viktig, men det finns fortfarande mycket att göra för att effektivisera energianvändningen i denna sektor. Flera av de intervjuade arbetade bara deltid med energifrågor och de upplevde att tidsbrist hindrade dem från ett effektivt energiledningsarbete. En rekommendation till företagen är därför att anställa en energiansvarig på heltid och/eller fler personer som kan arbeta med energifrågor. Det bör också läggas mer resurser på att engagera och utbilda anställda för att på så sätt introducera en företagskultur som främjar effektiv energianvändning.
