Abstract The use of plastics in products and packaging is growing. At the same time, the lifespan of packaging is short and consequently plastic waste volumes are growing in Finland and globally. Although separate collection and recycling of plastic packaging waste exists in Finland, it needs to be strengthened to reach the European Union’s targets. The separately collected plastic waste is mechanically recycled, but the recycling capacity is small, as is the process’s yield of secondary polymers. Hence, a large share of plastic packaging waste remains being recovered for energy. In our study, we first apply material flow analysis (MFA) to identify different routes of plastic packaging waste in Finland, and then we apply life cycle assessment (LCA) to quantify greenhouse gas (GHG) emissions of the current system and of alternative scenarios based on improvement measures. Domestic GHG emissions of the studied system were estimated to be 178 kt CO 2 e. Net GHG emissions including exports and credits from avoided production were estimated to be 155 kt CO 2 e. The results of the scenario assessment indicate that combining more measures offer significantly greater potential to reduce the system’s climate impacts, compared to individual measures. The results are complemented by a sensitivity analysis, helping with the interpretation of the results, understanding modelling challenges, and supporting robust decision-making. The study contributes to academic literature in two ways; it presents a robust, yet flexible way to integrate scenario-based, future-oriented modelling techniques into decision-making, and it assesses the various possibilities to improve the plastic recycling system to identify the quantitative improvement potential.

Abstract This paper describes and analyzes a workshop-based procedure to identify critical consumption and production (CP) linkages for sustainability, applied in the Klang Valley, an urban conglomeration centered in Kuala Lumpur and Putrajaya, Malaysia, targeting the year 2050. We propose a procedure combining a participatory backcasting approach, a structuralizing template, and scenario design cycles to identify critical CP linkages for sustainability. This procedure was tested in the Klang Valley, Malaysia, where resource and energy consumption is rapidly growing but scarcely studied. The workshops involved local experts from academia, industry, and government, as well as the research team, and established region-specific CP patterns, focusing on three domains, i.e., mobility, household chores, and living space. The results present key patterns for sustainable consumption and production in the Klang Valley and scenarios illustrating its implementation. Political will and strong regulatory enforcement with a particular focus on resource circulation at the end of life are identified as the dominant drivers to promote implementation.

The fashion industry has contributed to greenhouse gas emissions, hence global environmental pollution. Recent happenings in the fashion industry especially activities of fast fashion have promoted rapid production of apparel and accessories to meet the taste and preferences of consumers. These products have resulted in clothing waste ending up in landfills, or burnt in the open, which poses severe environmental risks. Considering this, a mini review was conducted to investigate sustainable technological innovations within circular fashion and bio-based materials which have been advanced in the fashion industry. These recent advances have influenced the possibility of ensuring a cost-effective solution for consumers, limiting waste, and reducing carbon emissions in the environment. Furthermore, we present a selection of case studies by brands and designers on new approaches and materials developed within the circular fashion concept and for bio-based materials. Findings show varying approaches and technologies developed within the circular fashion concept to reduce clothing waste products in the environment. Circular fashion has introduced approaches such as resale, repair, and rent models, the concept of recycling for textile waste, and the concept of disassembly in design which ensures the possibility of easily deconstructing the various parts of a product without any difficulty. Additionally, the development of bio-fabricated materials, bio-dyes, and do-it-yourself (DIY) materials from natural sources has promoted bio-materials with less environmental impact. Consumer perception remained an important element for effective sustainable fashion. Findings revealed that price plays a critical role in influencing consumers to purchase bio-based materials and recycled clothing, with others willing to buy these products due to the environmental impact. It is recommended for effective collaborative efforts between consumers, industry, and the government, for a positive mindset and shift towards a sustained fashion industry.
