Abstract In recent years, the growing popularity of plastic materials made from renewable biomass sources has prompted research on stakeholder views. This is because the circularity and decoupling credentials producing such materials can be substantial but also bring to the forefront pressing questions around public receptiveness and support. To this regard, primary research on public views towards this broad class of materials derived from bio-based sources remains sparse, highlighting a topic that requires further attention and examination across national terrains. In this research note, we focus on Greece and draw from semi-structured interviews with consumers and representatives of other key stakeholders to shed light on awareness, perceptions, attitudes, concerns and viewpoints on bioplastics. The preliminary findings indicate and further confirm issues that warrant the consideration of companies’ product development departments and offer insights in refining product presentation in the marketplace by informing marketing and communication activities. Likewise, these findings can feed into education or awareness-raising campaigns and programmes for the functional features, the terminology, the potential benefits and the proper disposal criteria of plastic products made from biogenic raw materials. Studies such as ours pave the way for a better understanding of how primary and secondary stakeholders perceive such bio-based interventions in the production system and shed light on evaluations, knowledge gaps and expectations affecting intentions to support relevant research-and-innovation outputs in the value chain. While we do not consider the study to be fully representative of the Greek population, insights drawn from the interviews do contribute to the body of knowledge encompassing stakeholders’ views which can inform the development of the industry.
近年来,由可再生生物质制成的塑料材料日益普及,促使了利益相关者观点的研究。这是因为产生此类材料的循环性和解耦性证书可能是实质性的,但也将围绕公众接受和支持的紧迫问题带到了最前沿。在这方面,关于公众对这类来自生物基来源的广泛材料的看法的初步研究仍然很少,突出了一个需要在全国范围内进一步关注和检查的主题。在本研究报告中,我们将重点放在希腊,并从与消费者和其他主要利益相关者代表的半结构化访谈中得出结论,以阐明对生物塑料的认识、看法、态度、关注和观点。初步调查结果表明并进一步确认了公司产品开发部门需要考虑的问题,并通过通知营销和沟通活动,为改进产品在市场中的展示提供了见解。同样,这些发现可以用于教育或提高认识的运动和方案,以了解生物原料制成的塑料产品的功能特点、术语、潜在利益和适当处置标准。像我们这样的研究为更好地理解主要和次要利益相关者如何看待生产系统中的这种基于生物的干预措施铺平了道路,并揭示了影响支持价值链中相关研究和创新产出意图的评估、知识差距和期望。虽然我们不认为这项研究能够完全代表希腊人口,但从访谈中得出的见解确实有助于形成包含利益相关者观点的知识体系,这些观点可以为行业的发展提供信息。

Abstract The focus on the transition to a circular economy has contributed to a growing research interest in repair. This paper investigates the role of independent repair, which consists of individuals, organisations, or businesses engaged in the repair of products without formal authorisation of the brand owners of these products. Repair—and independent repair in particular—is critical in achieving a paradigm shift that is anchored in regenerative sustainability. Especially in the electrical and electronics equipment sector, independent repair is challenged by difficult or expensive access to spare parts and repair information. This paper focuses on the independent electronics repair sector in Oslo. We implemented twenty-five semi-structured interviews with repairers working in commercial independent repair shops, focusing on challenges and opportunities in independent repair. They repaired a wide variety of products: mobile phones, desktop computers, laptops, tablets, cameras, printers, e-mobility batteries, remote-controlled cars, drones, and white goods. The thematic analysis of the interviews revealed three main findings. The independent repair sector employs different business models and strategies to tackle the challenges related to accessing affordable and quality spare parts. Secondly, independent repair fills the gap between expensive authorised repair, mostly covered by warranty or insurance, and discarding a broken product. Thirdly, independent repair has contributed to a circular spare part economy, both locally and on a global level. In the discussion, we address how repair can be understood as a regenerative practice, as well as how policy and regulation of repair, both on an EU and national level, supports or undermines independent repair.
对向循环经济过渡的关注促进了对修复的研究兴趣的增长。本文研究了独立维修的作用,独立维修由个人、组织或企业组成,这些个人、组织或企业在没有这些产品的品牌所有者正式授权的情况下从事产品的维修。修复——尤其是独立修复——对于实现以可再生可持续性为基础的范式转变至关重要。特别是在电气和电子设备领域,独立维修面临着获得备件和维修信息的困难或昂贵的挑战。本文主要研究奥斯陆的独立电子维修行业。我们对在商业独立维修店工作的维修人员进行了25次半结构化访谈,重点关注独立维修中的挑战和机遇。他们修理各种各样的产品:手机、台式电脑、笔记本电脑、平板电脑、相机、打印机、电动汽车电池、遥控汽车、无人机和白色家电。对访谈的专题分析揭示了三个主要发现。独立维修部门采用不同的商业模式和策略来应对与获得价格合理、质量良好的备件相关的挑战。其次,独立维修填补了昂贵的授权维修(大多由保修或保险覆盖)和丢弃破损产品之间的空白。第三,自主维修促进了本地和全球范围内的零部件循环经济。在讨论中,我们讨论了如何将修复理解为一种再生实践,以及欧盟和国家层面的修复政策和法规如何支持或破坏独立修复。

Abstract The financial industry can play a significant role in reaching the sustainability goals. But there is a lack of attention to the part financial advisors can or should play. By advising SMEs on sustainability, financial advisors are in the position to make a large impact. To do that, financial advisors must not only advise on creating financial value but also on social and ecological value. By advising on creating multiple value and applying integrated thinking, financial advisors can provide sustainable financial advice to SMEs. And because of the large and diverse number of financial advisors for SMEs, they can make a difference in helping SMEs to become more sustainable. This article focuses on the role financial advisors can play and the impact they can make for SMEs in their challenge to become more sustainable. By combining theory on the value of advice, multiple value creation, and integrated thinking, specifically related to the challenges of SMEs on sustainability, the result is a definition of sustainable financial advice to stimulate the debate on the specific role of financial advisors in reaching the sustainability goals worldwide. Sustainable financial advice is financial advice with integrated thinking about multiple value creation with the aim to reach the sustainability goals.
金融业在实现可持续发展目标方面可以发挥重要作用。但人们对理财顾问能够或应该发挥的作用缺乏关注。通过向中小企业提供可持续发展方面的建议,财务顾问可以产生很大的影响。要做到这一点,财务顾问不仅要提供创造财务价值的建议,还要提供社会和生态价值的建议。财务顾问通过提供创造多重价值的建议,运用整合思维,为中小企业提供可持续的财务建议。由于中小企业的财务顾问数量众多,种类繁多,他们可以在帮助中小企业变得更可持续方面发挥作用。这篇文章的重点是财务顾问可以发挥的作用和影响,他们可以使中小企业的挑战变得更加可持续。通过结合建议价值理论、多重价值创造理论和综合思维理论,特别是与中小企业在可持续发展方面的挑战相关的理论,得出了可持续财务建议的定义,以激发关于财务顾问在实现全球可持续发展目标方面的具体作用的辩论。可持续财务建议是综合考虑多种价值创造的财务建议,旨在实现可持续发展的目标。

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.
塑料在产品和包装中的使用越来越多。与此同时,包装的使用寿命很短,因此塑料废物量在芬兰和全球都在增长。虽然芬兰存在塑料包装废弃物的单独收集和回收,但需要加强,以达到欧盟的目标。单独收集的塑料垃圾是机械回收的,但回收能力很小,因为该过程的二次聚合物产量也很小。因此,很大一部分塑料包装废弃物仍被回收用于能源。在我们的研究中,我们首先应用物料流分析(MFA)来确定芬兰塑料包装废弃物的不同路线,然后我们应用生命周期评估(LCA)来量化当前系统的温室气体(GHG)排放以及基于改进措施的替代方案。所研究系统的国内温室气体排放量估计为178千吨二氧化碳e。包括出口和避免生产的信用额在内的温室气体净排放量估计为155千吨二氧化碳e。情景评估的结果表明,与单独的措施相比,结合更多的措施可以提供更大的潜力来减少系统的气候影响。结果由敏感性分析补充,有助于解释结果,理解建模挑战,并支持稳健的决策。该研究在两个方面为学术文献做出了贡献;它提出了一种强大而灵活的方法,将基于场景的、面向未来的建模技术集成到决策中,并评估了改进塑料回收系统的各种可能性,以确定量化改进的潜力。

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.
摘要本文描述并分析了一个基于研讨会的程序,以确定可持续发展的关键消费和生产(CP)联系,应用于巴生谷,一个以吉隆坡和布城为中心的城市群,马来西亚,目标是2050年。我们提出了一种结合参与式回溯法、结构化模板和场景设计周期的程序,以确定可持续发展的关键CP联系。这个程序在马来西亚巴生谷进行了测试,那里的资源和能源消耗正在迅速增长,但几乎没有研究。研讨会邀请了来自当地学术界、工业界和政府的专家以及研究团队,并建立了特定区域的CP模式,重点关注三个领域,即流动性、家务和生活空间。研究结果提出了巴生谷可持续消费和生产的主要模式,并说明了其实施情况。政治意愿和强有力的监管执法,特别是关注生命周期结束时的资源循环,被认为是促进实施的主要驱动因素。

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.
时装业造成了温室气体排放,从而造成了全球环境污染。最近在时尚行业发生的事情,特别是快时尚的活动促进了服装和配饰的快速生产,以满足消费者的品味和偏好。这些产品导致服装废料最终被填埋,或在露天焚烧,这构成了严重的环境风险。考虑到这一点,我们进行了一项小型审查,以调查循环时尚和生物基材料中的可持续技术创新,这些创新已经在时尚产业中取得了进展。这些最近的进展影响了确保为消费者提供具有成本效益的解决方案、限制浪费和减少环境中的碳排放的可能性。此外,我们还介绍了一些品牌和设计师在循环时尚概念和生物基材料中开发的新方法和新材料的案例研究。调查结果显示,在循环时尚概念中开发了各种方法和技术,以减少环境中的服装废物。循环时尚引入了转售、维修和租赁模型等方法,回收纺织废料的概念,以及在设计中拆卸的概念,确保了轻松解构产品各个部分的可能性,没有任何困难。此外,生物制造材料、生物染料和天然DIY材料的发展促进了对环境影响较小的生物材料的发展。消费者的看法仍然是有效的可持续时尚的一个重要因素。调查结果显示,价格在影响消费者购买生物基材料和回收服装方面起着关键作用,其他人因为环境影响而愿意购买这些产品。建议消费者、产业和政府之间进行有效的合作,形成积极的心态,向可持续发展的时尚产业转变。
{"title":"A Review of Circular Fashion and Bio-based Materials in the Fashion Industry","authors":"Raphael Kanyire Seidu, Benjamin Eghan, Richard Acquaye","doi":"10.1007/s43615-023-00303-z","DOIUrl":"https://doi.org/10.1007/s43615-023-00303-z","url":null,"abstract":"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.","PeriodicalId":72595,"journal":{"name":"Circular economy and sustainability","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135059632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
