The clothes and textiles sold in Sweden is mostly manufactured in countries outside of the EU. The production requires large areas of land and vast amount of water. The environmental impact is big during the production phase in terms of water usage, chemicals and transports. In general, the consumption of new textile is increasing in Sweden, but so is also reused textil. In 2016 the consumption of textile in Sweden was nearly 14 kg per person and year, which equals the weight of 14 t-shirts, 5 pairs of jeans, 7 hoodies and 2 coats. At the same time 5 kg textile per person and year is thrown in the the household waste and nearly 60 % of the thrown textile is in good condition and could be used again. The amount of clothes given to charity organisations is almost 4 kg per person and year but 70 % of the collected textile is exported. The collection and recycling of non-reusable textiles in Sweden today is low. Current recycling techniques are mainly energy recovery through incineration. The reasons for this has to do with limitations in the sorting and collection of consumer textile waste or limitation of optional recycling processes. In fact, there is no large scale industrial process to recycle textile into new textile, which leads to an open loop system where input of new materials is required. But there are upcoming technologies that meets the challenges today. This project explores the dynamics of current ways of treating textile waste. Through learnings from existing system, in combination with new technologies, alternative ways of structuring processes of production, consumption, usages and disposal is proposed with the aim of establishing a new relationship to contemporary urban production.

In this study, possible cleaner production opportunities for a dairy processing facility are examined, considering the market milk production process. Cleaner production concept and its key tools of implementation were analyzed to build the basis of study. General production process and its resulting environmental loads are discussed by taking possible CP opportunities as the axis of study.

The EU has embarked on a resource efficiency trajectory in order to solve resource scarcity and general sustainability issues. The conversion of food waste into fuel is considered resource efficient as it makes use of resources that would otherwise be discarded. On the other hand, the food sector affects the environment substantially as it is inherently resource intensive and excessive. The purpose of the study was to assess how resource efficient the food waste substrate (feedstock for energy production) is from a life-cycle perspective. The study also aimed to determine if associated Swedish incentives and current market signals promote resource efficiency in Sweden. The food waste substrate has a complex life-cycle and current analyses neglect crucial life-cycle impacts. This makes resource efficiency difficult to determine in absolute terms. The first resource efficiency principle, that promotes the use of fewer inputs, becomes questionable as the food waste substrate has twice as many input stages in comparison to the food crop substrate. The second principle, stating that the food waste substrate should contribute to a low-carbon economy, also falls short due to a calculation method that neglects crucial emission stages. Due to the absent life-cycle perspective, crucial environmental impacts associated with food production are neglected. This affects the achievement of the Swedish Generation Goal and environmental quality objectives. The study concludes that the food waste substrate should undergo a thorough life-cycle analysis. Furthermore, it should be compared to other biofuel options in order to determine degree of resource efficiency. Only then can an appropriate set of EU and national policy measures be instated to safeguard scarce resources and promote a sustainable agriculture and energy sector.

A produção de couro acabado ocorre a partir das peles obtidas nos frigoríficos e se dá pelo uso de grande volume de água e de uma ampla gama de produtos químicos associados a diversas operações mecânicas e gera, além do produto desejado, diversos tipos de resíduos, causando impactos ambientais significativos. Os resíduos sólidos gerados destacam-se pelo volume e potencial poluidor. Os empreendimentos gaúchos são obrigados a emitir e submeter regularmente, ao órgão ambiental licenciador, relatórios dos resíduos sólidos gerados e destinados, no entanto, não há a disponibilidade da informação das tipologias e da quantidade de resíduos sólidos gerados no estado do Rio Grande do Sul, sendo que o último inventário publicado data de 2002. O conhecimento a cerca da geração e destinação dos resíduos é de suma importância para subsidiar a tomada de decisões sobre o assunto, seja com relação à formação de políticas públicas, seja para a priorização de investimentos ou para definição de áreas para empreender esforços técnicos e científicos. A avaliação ambiental do gerenciamento dos resíduos sólidos oriundos da produção de couros no Rio Grande do Sul consiste de uma pesquisa descritiva exploratória, de natureza qualitativa e quantitativa, formando um estudo de caso do gerenciamento de resíduos do setor coureiro do estado. Este trabalho inclui uma breve apresentação do processo de produção de couros, os aspectos e impactos ambientais oriundos deste, os resíduos sólidos gerados e as tecnologias de tratamento e destinação final dos mesmos, com ênfase nas formas de valorização mediante a reutilização e processos de reciclagem, upcycling e downcycling, com a geração de possíveis subprodutos e coprodutos. Aborda ainda, as premissas do gerenciamento de resíduos, os requisitos legais e as oportunidades de Produção Mais Limpa aplicáveis ao gerenciamento de resídos sólidos. A partir do Sistema de Gerenciamento e Controle de Resíduos Sólidos Industriais – SIGECORS de 2013 e 2014 (FEPAM, 2016A) foi verfificado a geração anual de 112.642,5 toleladas de resíduos, mais 129.107,3 metros cúbicos de resíduos e mais 88.877 unidades (embalagens e lâmpadas), sendo que a geração de resíduos perigosos foi ligeiramente inferior a de não perigosos. Os principais resíduos sólidos gerados, em termos quantitativos, são os oriundos dos sistemas de controle de poluição (principalmente lodos de estações de tratamento de efluentes), seguidos dos resíduos de couro (basicamente curtidos ao cromo) e dos resíduos oriundos das peles (de processos antes do curtimento). No que se refere a resíduos não perigosos – Classe II, foi verificado que a prática dos processos de reciclagem, upcycling e downcycling, resultando em coprodutos e subprodutos, atingiu um desempenho superior a 95%. Quanto aos resíduos perigosos - Classe I, o nível de aproveitamento foi menor (no entanto bem superior ao padrão registrado em 2002) sendo que o lodo gerado nas estações de tratamento de efluentes é o resíduo mais problemático do setor, não havendo ainda uma alternativa de aproveitamento disponível. Por meio da avaliação ambiental realizada conclui-se que o diferencial ambiental do setor no RS está na aplicação sistêmica de processos de valorização de resíduos, incluindo a reutilização de resíduos, a prática de upcycling, transformando resíduos em coprodutos, a reciclagem, e a prática de downcyclig, transformando resíduos em subprodutos. / Rio Grande do Sul state concentrates around one third of productive leather units in Brasil, which has a significant role in this sector. Finished leather production starts with the skins obtained from slaughterhouse and consumes a large amount of water and a great number of chemical products, combined with different mechanical operations. It results not just in the desired product, but also in different kinds of waste, causing significant environmental impacts. Among the produced wastes, solid ones stand out, mainly due to its large amount and their pollutant potential. Even though enterprises from Rio Grande do Sul are forced to regularly issue and submit a report on produced and allocated solid waste to the environmental commission agency, there is not available information about typologies and solid waste produced in the state of Rio Grande do Sul, and the last inventory dated 2002. Knowledge about waste production and its disposal is very importance in order to support decision making on the present subject, either to create public policy and decide where to invest, or to define in which areas technical and scientific efforts must be performed. Management environmental evaluation of solid waste from leather production in Rio Grande do Sul consists in a qualitative and quantitative exploratory research, creating a case study about the leather sector management in the state. This dissertation includes a brief presentation on leather production process, its aspects and environmental impacts, the solid waste generated, treatment technologies and its final disposal, with emphasis on forms of recovery through recycling processes, upcycling and down cycling, considering the generation of possible byproducts and coproducts for the leather industry. It also addresses waste management assumptions, legal requirements and applicable opportunities from Cleaner Production to solid waste management. From “Sistema de Gerenciamento e Controle de Resíduos Sólidos Industriais” – SIGECORS of 2013 and 2014 (FEPAM, 2016A) it was observed an annual generation of 112,642.5 tons plus 129,107.3 cubic meters of waste. In addition, it was found a generation of 88,877 units (packaging and light bulbs), and the dangerous waste production was slightly lower than the non dangerous ones. The main solid wastes generated, in quantitative terms, come from pollution control systems (especially sludge from effluent treatment stations), followed by leather wastes (basically tanned via chromium) and by wastes from skins (in processes performed before tanning). About non dangerous wastes – Class II, it was found that recycling practices, upcycling and down cycling, which results in coproducts and byproduct, achieved a performance higher than 95%. About the dangerous wastes – Class I, the reclamation was lower (however much higher than the registered standard in 2002) and the produced sludge from effluent treatment stations is the most problematic waste in the sector. There is not yet an available alternative to recycling. By the environmental evaluation performed, it is concluded that environmental differential in this sector in Rio Grande do Sul is in the systemic application of waste appreciation processes, which includes reuse of waste, upcycling execution, transforming waste in coproducts, recycling, and down cycling execution, transforming waste in byproducts.
