This thesis presents the research of packaging beer into plastic bottles and the design and manufacture of a low pressure bottle blow moulding machine for demonstration purposes. The machine will be used for the production of plastic bottles suitable for bottling brewed beer at the microbrewery at Massey University Palmerston North. Premanufactured PET preforms have proven to be the most convenient and promising choice for the fabrication of blown bottles. Basic tests to understand the behaviour of the preforms and the challenges of the blowing process have been carried out. A special focus has been placed on the different circumstances at University in contrast to industrial bottle production in particular the needed air pressure to form the bottles. The following step was to find the ideal method and principle to handle the preforms and to transform them in the desired shape. Finally the design, drawing of the parts and assemblies were carried out with the 3-D CAD software Solidworks. The designed parts for the bottle blower have been manufactured at the mechanical Workshop at Massey University. To control the bottle blower, the National Instruments USB interface was selected which required the design and manufacture of an additional driver interface card to protect the USB interface and convert the TTL levels into higher voltage. The final assembly and testing of the blower then concluded the practical work for this master project. A suitable design for the bottle production was found and the assembled Bottle Blower can now be used for the production of PET bottles.

This is a Minor Fields Study (MFS) project with the aim to facilitate the handling of empty PET bottles in Uganda. The eight weeks in Uganda gave an insight in how products are produced and how the waste surplus material is managed by local producers as well as factories. During the time in Uganda a problem concerning waste management of used PET-bottles was discovered as well as a need for a concept that facilitates the handling of PET bottles in restaurants and hotels. This thesis describes the development of a product prototype, which is designed by following product design process and from the knowledge gathered in Uganda. The product is designed to be manufactured and used in Uganda. The main purpose of the product is to compress used PET-bottles, to accomplish a size reduction. This will make it easier to gather the bottles and transport them to a recycling plant. / Detta är ett Minor Field Study (MFS) projekt som har resulterat i en prototyp till en produkt som ska underlätta hanteringen av använda PET-flaskor i Uganda. Projektet påbörjades i Uganda under 8 veckors tid, där man undersökte hur restmaterial hanteras i lokala verkstäder och fabriker. Då uppmärksammades ett stort behov av ett koncept som underlättar hanteringen av PET flaskor, främst i restauranger och hotell. Denna rapport beskriver hur en prototyp har utvecklats utifrån produktdesign metodik och erfarenheter i fält. Prototypen är utvecklad på så vis att den ska kunna byggas och användas i Uganda. Produktens huvuduppgift är att trycka ihop använda PET flaskor vilket medför en storleksminskning. Detta i sin tur underlättar förvaringen av flaskorna men underlättar också transporten till en återvinningsanläggning.

Foram avaliados três sistemas comerciais convencionais, um apresentando barreira aos gases, e um último desenvolvido para o trabalho, consistindo em um sistema híbrido de vedação elaborado com materiais plásticos e metálicos. Utilizou-se nos experimentos garrafas de 600 mL, em pré-formas de 23, 25 e 28g. A concentração de CO2 na água foi medida semanalmente através da leitura da pressão do espaço livre das embalagens durante o período de 3 meses. Os resultados mostraram que a retenção do CO2, em todos os sistemas testados, está diretamente relacionada à temperatura de estocagem. Na temperatura de 35°C, os sistemas se diferenciaram para garrafas de maior massa (25g e 28g). Na temperatura de 25°C, observou-se ganhos significativos de retenção quando se utilizou sistemas de fechamento considerados barreira. Já na temperatura de 5°C foram testados apenas os sistemas comerciais que não apresentaram, no período estudado, variações significativas da retenção de CO2 / Abstract: This study had the aim to evaluate CO2 retention in PET bottles filled with carbonated and drinkable water using different closure systems studied in 3 different storage conditions, 5, 25 and 35°C. It was evaluated 4 commercial closure systems: 3 of conventional type and one with O2 and CO2 gas barrier; and also it was developed a 5th kind for this experience: a hybrid closure system composed by plastic and metallic materials. All 5 types of closures were tested in 23g, 25g and 28g PET bottles of 600mL. The CO2 concentration in the carbonated water was weekly measured through the packaging free space pressure during 3 months. The results indicate that retention of CO2, in all closure systems tested, was straightly related with storage temperature. At 35°C for 25g and 28g bottle systems were observed significant different values. At 25°C storage condition, significant difference of gas retention was observed where a barrier closure was tested. At refrigerated temperature (5°C) only commercial closures were tested and all of them did not show ¿ in the studied period ¿ significant variation of CO2 retention / Mestrado / Mestre em Tecnologia de Alimentos

As características típicas dos polímeros sintéticos, como seu custo praticamente irrisório, baixo peso, boa resistência mecânica, impermeabilidade, transparência e capacidade de coloração mais impressão lhe conferiram trunfos irresistíveis para seu uso massivo na forma de embalagens, uma aplicação extremamente importante numa sociedade voltada para o consumo. O grande problema dos polímeros sintéticos reside na sua curta vida útil, o que conduz a um rápido aumento da corrente de resíduos, como é o caso das embalagens. Dentro desse âmbito, a reciclagem passa ser uma alternativa promissora. Por definição, a reciclagem é um processo de transformação dos materiais previamente separados para posterior utilização; é a recuperação de resíduos mediante uma série de operações que permitem que materiais processados sejam aproveitados como matéria-prima no processo gerador ou em outros. A primeira etapa deste trabalho foi a tentativa de fazer a despolimerização de PET utilizando o processo de destilação molecular. Os resultados mostraram que não é possível utilizar o destilador molecular na despolimerização do PET. Na segunda etapa deste trabalho o pet pósconsumo foi submetido à recristalização para remoção do corante, utilizando ácido trifluoracético como solvente, na tentativa de uma nova alternativa de reciclagem para este material. O material modificado e o PET pós-consumo foram caracterizados por termogravimetria (TG) e calorimetria exploratória diferencial (DSC) / Abstract: The use of synthetic polymers in the world and particularly in Brazil has been increasing for decades representing the huge success achieved by these materials in various applications. The main characteristics of synthetic polymers are their low cost and weight, good mechanical strength, impermeability, transparency and the possibility of coloring, which results in their massive use in the form of packaging an application extremely important in a society focused on consumption. Despite all its advantages, the polymers are generally used in the manufacture of objects whose useful life it is extremely short, like bottled water and soft drinks , produced with polyethylene terephthalate (PET), or as previously mentioned, in packs of all species, resulting in a rapid increase in the waste stream. In this scenario, recycling becomes a promising alternative. By definition, recycling is a process of transformation materials previously separated for later use or is the recovery of waste by means of a series of operations that allow processed materials to be utilized as raw material in generating process or in other process. The first stage of this work was to attempt to make the depolymerization of PET using molecular distillation process, but results showed that it is not possible to use the molecular distiller for the depolymerization of this type of polymer. In the second stage of the work, post-consumer PET was subjected to recrystallization to remove the dye, using trifluoroacetic acid as solvent in in a new attempt to recycle this material. The modified material and post-consumer PET were characterized by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) / Mestrado / Desenvolvimento de Processos Químicos / Mestra em Engenharia Química

This thesis deals with the recycling of polyethylene terephthalate and its subsequent processing into the form of a regranulate meeting the parameters required for food use. A brief description of recycling technology, PET flake quality rating and input material contamination is provided. Additionally, legislation regarding recycling for food purposes is discussed and regranulation technologies are described. The suitability of these technologies for processing specific flake samples has been confirmed. In the experimental part, differences in the regranulate samples are compared using DSC and FT-IR. It has been found that there are no major differences between food quality samples. Tests were carried out on 200 PET bottles (bottle, label), on which the input material was divided into 16 groups. Groups that are unsuitable for recycling with this technology was defined. In addition, contaminants of the final product were examined. Their approximate composition was determined and the relationship between the labels of the bottles at the inlet and the impurities at the outlet was found. Appropriate solutions have been proposed to reduce this contamination

Through interviews, research, observations and the use of service design methods the author of this report, Jenny Annebäck, executed a Minor Field Study within the field of recycling of PET bottles in Uganda. The project work resulted in thorough studies of service design thinking and methodology, sustainable development, the market and situation in Uganda as well as the consumer group concerned about sustainable development. The result was a pre-study of a future development of a recycling service, visualized through two stakeholder maps, personas and a customer journey map. These three tools constitutes a beginning and a solid ground for further work with developing the service. A service that can contribute to a more sustainable development in the country of Uganda.

This thesis deals with economy of treating with municipal waste. The municipal waste, which is generated by citizens makes burden not only on public and private budgets, but also on environment. Importance of this burden rise regarding to continuous growth of volume of the municipal waste. This fact implicates need to set up cost efficient and permanent achievable solution. Nowadays there is a suggestion, prepaderd by the Ministry of environment, which suggest using returnable PET bottles, which are important part of the municipal waste. Potentional implementation of returnable PET bottles doesnt have influance only on yield of this type of waste, but it is connected with other parts of the municipal waste such as biological degradable municipal waste and mixed waste. Content of this thesis is presentation of the economic analysis of alternation for treating with three most important parts of the municipal waste on backround of fullfiling conditons set up by European union.

Denna studie kartlägger vilka insamlingsmetoder för PET-flaskan som finns för avfalls- och återvinningsfasen på den svenska marknaden samt vilka verksamheter som ansvarar för dessa. Vilken omställning som görs av verksamheterna för att uppnå fossilfrihet, gällande insamlingsmetoder, energi- och drivmedelsanvändning. Tidigare forskning, djupintervjuer och enkäter ligger som grund för de resultat som presenteras. Studien tittar även på miljömässiga påverkansfaktorer men även komplexiteten gällande kommunala och rikstäckande verksamheter, hur de jobbar med hantering av PET på den svenska marknaden samt deras användning av fossila resurser och vad som görs för att minska sin miljömässiga påverkan. Insamlingsmetoderna dit PET-flaskan kan nå är restavfall, fastighetsnära insamling, återvinningsstationer och pantstationer. Verksamheternas ansvarsområde sker både rikstäckande och på kommunal nivå. Nulägesanalysen indikerar att verksamheter behöver göra ytterligare åtgärder för att bli helt fossilfria men att det sker en omställning med åtgärder för energi och transporter för att uppnå detta. Det finns insamlingsmetoder som möjliggör återvinning, men där sorteringsmetoderna kan vara avgörande för att PET ska kunna återgå till rätt materialflöde. Det går att se att verksamheterna använder förnyelsebar energi och drivmedel och att de aktivt arbetar mot att bli helt fossilfria. / This study identifies which collection methods for the PET bottle are available for the waste and recycling phase on the Swedish market and which businesses are responsible for these methods. What adjustment is being made by the operations to achieve fossil-free, current collection methods, energy, and fuel use. Previous research, in-depth interviews and questionnaires form the basis for the results presented. The study also looks at environmental impact factors but also the complexity of municipal and nationwide activities, how they work with handling PET in the Swedish market and their use of fossil resources and what is done to reduce their environmental impact. The collection methods that the PET bottle can reach are residual waste, collection close to the property, recycling stations and pawn shops. The area of ​​responsibility of the operations takes place both nationwide and at the municipal level. The current situation analysis indicates that businesses need to take additional measures to become completely fossil-free, but that there is a change with measures for energy and transport to achieve this. There are collection methods that enable recycling, but the sorting methods can be crucial for PET to be able to return to the correct material flow. You can see that the companies use renewable energy and fuel and that they are actively working towards becoming completely fossil fuel.

The graduation thesis deals with the use of logistics in the brewery Pivovar Protivín a. s. The paper presents a view of the current situation of Czech breweries in the Czech Republic as well as in the world. It maps the trends of recent years in the brewing industry and shows how Czech breweries have faced up the economic crisis. The results of Pivovar Protivín are presented and compared with the results of Svijany brewery. The distribution of Protivín brewery products is analyzed. Based on the analysis, the time frame of beer delivery to customers is made. Further on, the questions of the packaging management in Protivín brewery are dealt with. Breweries are specific for complex and expensive reverse logistics of returnable packaging. The question whether producing beer in PET bottles would be appropriate for Protivín brewery is studied. Determining the level of services provided for brewery customers is examined. According to the results presented here, the greatest demands on services provided by breweries appeared to be those by the customers in gastronomy sphere. Based on the questionnaire investigation, the standards in providing brewing services were set together. Finally, I suggested possible improvements that should lead to cost savings, greater flexibility of operations and competitive advantages for the Protivín brewery as well as for the whole K Brewery Group.
