“…The most commercialized bioplastics in terms of production volumes are PLA and starch-based plastics . However, recycling technologies are still being developed, and only a few studies of LCA have been conducted using laboratory data. , The use of the bioversions of conventional monomers to replace the petroleum-based plastics is advisable in the future, because these bioplastics can readily enter existing processing and recycling systems. Specifically, bio-PE and bio-PP are among the most promising alternatives to petroleum-based plastics.…”

In light of the global climate crisis and commitments toward net-zero carbon emissions, this Perspective evaluates the current status of developments in recycling methods and bioplastics to identify long-term sustainable alternatives. The recycling and product application of major medical plastics, including poly(vinyl chloride) (PVC), polyethylene (PE), polypropylene (PP), and polystyrene (PS), are discussed, and their circular potential is evaluated. Researchers are actively investigating bioplastics to solve present concerns and curb the global increase in greenhouse gas (GHG) emissions from petroleum-based plastics. Current recycling methods for PE and PP can be scaled up, and bioversions of plastics, such as bio-PE and bio-PP, can be used as a long-term sustainable solutions to realize their circular potential. As an alternative to PVC and PS, materials with inefficient recycling methods, recent promising bioplastics such as polyurethane (PU) and poly(lactic acid) (PLA) have a competitive performance. Our Perspective recognizes the need for further research on issues such as integrated recycling processes and the possibility of commercializing bioplastics.

“…One company mentioned that their goal was to have their products circulating in the system for as long as possible. High quality makes it possible for products to stay in use for longer and even have several users, but it also makes it possible to recycle the materials at the end of the product lifespan through mechanical or chemical recycling technologies [38]. This is one reason why quality is controlled to such a great extent in the sampling and production phases.…”

Fit for the Future: Garment Quality and Product Lifetimes in a CE Context

The fashion industry is one of the most polluting industrial sectors in the world and its environmental impacts are huge. Garments are produced effectively at a low price, are of low quality, and are used for a very short time before ending up in increasing textile waste streams. One critical aspect in this context is the lifetime of a garment. Short garment lifetimes are the results of low quality and consumer dissatisfaction, or consumers’ constant search for newness, resulting in the early disposal of garments. This study focused on the issue of garment quality and how it can be connected to product lifetime. The research used a case study approach, including company interviews about working for quality, and aimed to expand on the topic of how quality impacts product lifetimes. Data analysis was conducted according to the principles of descriptive analysis and the discussion expanded to the circular economy context, creating an extended understanding of garment quality in a circular economy.

“…Among its recommendations, it proposes that: "sorting on woven qualities for instance or separating bales of lower and higher qualities of woolen (sic) textiles, could enable them to be used for different product applications, and hence avoid waste being created later in the value chain" (Fibersort, 2020:15) However, the importance of this category is contended. Niinimäki and Karell (2020) point out that although a greater understanding of the effects of the structure of our textiles for recycling is required, this is only relevant to chemical recycling and not mechanical recycling. Whilst it is true that the structure of textiles matters little when mechanically recycling low grade textiles into non-woven applications, for higher grade mechanical recycling the industry distinguishes between the structures to obtain quality fibres (Hall, 2018).…”

Background: The problem of difficult-to-recycle textile waste is an ongoing challenge. One of the issues is the lack of exchange between the recovery sector and design/manufacture of recycled materials. This paper seeks to addresses the gap in knowledge between sorting (in recovery) and blending activities (in manufacture), expanding current design strategies towards textile recovery. To achieve this, the research explores sorting practices of wool/acrylic blends in the mechanical wool recycling industry and applies this knowledge to the design of new yarns. Methods: A bricolage of methods was used to conduct this research in three parts. First, an overview of a previous study by Author1 is presented from which this research builds. Second, field research using conversation methods with the owner of a closed wool recycling company was conducted centring around their material archive. Thirdly, practice research was conducted in a spinning facility where Author1 applied knowledge from part 1 and 2 by designing four recycled yarns. This was supported by interviews with a sorter and recycler to expand on the findings. Results: Four methods of sorting and the sorting grades/thresholds that are found in the wool recycling industry are outlined, and five methods of recycled blending historically used in the wool recycling industry are established. This knowledge (sorting methods/grades and recycled blending techniques) were applied in practice and from the methods employed, the relationship between sorting in recovery and recycled blending in manufacture was established across three themes: fibre quality, fibre type and fibre colour. Conclusions: The paper concludes that understanding the link sorting and blending provides the foundations for a ‘Design for Sorting’ methodology. When lessons from each theme (quality, type and colour) are combined, this enables fibre value to be retained in recovery and thus, provides a route for longevity of our textile fibres.
