In recent years, the European Union (EU) has launched policies that increasingly define, classify, manage, and restrict plastics. At the same time, the emergence of biobased and biodegradable plastics has raised new questions about how these materials may be impacted by existing legislation. How emerging biobased polymers are defined and regulated across EU legislation and inconsistencies in definitions of key terms such as biobased, bioplastic, and chemical modification have been critically assessed. To support innovation, a simplified decision tree is presented — based on existing regulatory and scientific frameworks — enabling clearer classification of polymers and synthetic polymeric microparticles (commonly referred to as primary microplastic). Unlike existing decision trees, this framework also identifies which plastic regulations apply and from which a polymer may be exempted. Case studies of cellophane, PLA/PHA, protein-based polymers, lignin, biobased microcapsules, and rubber demonstrate how the decision tree can be applied in practice, revealing ambiguities and potential misinterpretations. Biobased plastics are not automatically exempt from regulation but are generally treated like conventional plastics unless they meet strict criteria. Harmonized definitions and life cycle thinking are essential to avoid misconceptions and regrettable substitutions. Practical guidance for scientists, material developers, and regulators to navigate the evolving field of biobased plastics in the context of the EU plastics policy landscape, and advance safe and sustainable polymer innovation is provided.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"29 ","pages":"Article 200319"},"PeriodicalIF":6.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146188219","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}

Based on a survey of 954 participants from a Canadian population, the study finds that while most consumers understand the distinction between best-before and use-by labels, most consumers still rely heavily on date labels, often discarding edible food due to perceived safety concerns. Importantly, the relationship between label knowledge and waste behavior is shaped by food-related risk taking: This study supported that individuals with higher risk-taking tolerance successfully act on their knowledge of date labels to reduce waste, supporting the hypothesis that risk-taking moderates this effect. Meanwhile, environmental values directly predict lower food waste but do not significantly moderate the effect of knowledge, suggesting that pro-environmental consumers may already follow sustainable food management practices independent of label understanding. The model also confirms that household food waste predicts household financial loss, with an estimated average cost of CAD 246 per year attributable to misinterpreting date labels. These findings underscore the complexity of consumer behavior and the need for targeted interventions. Educational campaigns should be tailored to different risk profiles, and label redesigns should incorporate sensory cues to build confidence in food safety assessments.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"29 ","pages":"Article 200300"},"PeriodicalIF":6.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145546769","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}

The purpose of this literature review is to systematize the models and approaches that are suitable for predicting the amount of municipal solid waste (MSW). Based on systematically explored literature analysis (used Scopus database in 2023) methodologies, a recommendation framework is developed to underpin the design of municipal solid waste management systems by recording possible models and proxy variables in addition to presenting their advantages and limitations based on the 78 papers that met the selection criteria. The proposed framework identifies possible model structures according to the municipal solid waste management analysis task and data availability, which fills the gap and lays the foundations for data-based decision support in goal-oriented municipal solid waste management. A total of 36 AI-driven models are explored and catalogued using 455 proxy variables. Depending on the number of observations and the set of available proxy variables, a model structure framework is provided, based on which the identification of models can be optimized for the completion of goal-oriented municipal solid waste predicting tasks. This literature review provides a basis for meeting the goal-oriented MSW modeling tasks at a higher level, as it also proposes a model catalog, data inventory and model structures, and discusses how to address the challenges that may arise for the models.

This study undertakes a systematic literature analysis of CDW market development within a CE framework, combining bibliometric analysis and critical review to identify key market dynamics, stakeholder roles, regulatory challenges, and innovative business models. The findings reveal persistent barriers, including fragmented regulations, inconsistent standards, and economic constraints, particularly in regions with inadequate recycling infrastructure. To address these challenges, this study proposes the Circular Market Strategic Framework for CDW (CMSF-CDW), aligning policy harmonization, financial incentives, advanced recycling technologies, and stakeholder collaboration to foster resilient and scalable markets for recycled CDW materials. The study emphasizes the need for region-specific policies, scalable digital tools, and further efforts on CE implementation to enhance resource efficiency and drive market growth. Key findings highlight the central role of public-private partnerships in aligning market incentives with regulatory goals, the importance of digital traceability tools in building trust and material transparency, the effectiveness of green procurement and certification schemes in accelerating demand for recycled CDW products, and the need to align performance-based standards with procurement protocols to create stronger market signals and investor confidence.

Thus, prompting sustainable production and consumption models, according to the UN sustainable development goal n.12, in these industries is essential. Developing industrial symbiosis (IS) practices between the textile and the furniture industries, through the use of textile industrial waste as input for producing furniture products and successfully marketing these products (IS products) can represent a key way to achieve this goal. A widespread diffusion of IS products in the market is needed to really lead to a reduction of environmental burdens. A deep knowledge of consumer perceptions and behavioral intentions towards IS products is thus needed. To this aim, a survey of 1156 Italian consumers has been conducted, with a specific focus on IS sofas. Results show that consumers perceive these products as being characterized by a high degree of green utility. Consumers also declare not to be willing to accept a worsening of performance, especially comfort and quality. While about 77 % would consider purchasing, a much lower percentage (&lt;50 %) declare a high likelihood of purchasing such products. About 90 % of consumers state they are willing to pay a premium price for an IS sofa. Several aspects that would increase the purchase intention of an IS sofa are also identified. Consumer’s knowledge on is found to play a prominent role in positively influencing consumer’s perceptions and behavioral intention, as significant differences between respondents with a high level of IS knowledge and those with a low level are highlighted for attitude, purchase intention, green perceived utility, and for some factors that would increase the purchase intention.

However, the environmental implications of FRP remain a concern, predominantly due to energy-intensive production processes and end-of-life (EoL) challenges. This review offers a comprehensive, cross-sectoral analysis of life-cycle assessment (LCA) findings on FRP, highlighting sector-specific drivers, environmental trade-offs, and methodological limitations. Although use-phase benefits, such as reduced emissions and lower maintenance costs, are well documented, they are often offset by the high embodied energy and underdeveloped recycling infrastructure. Existing LCA studies have emphasized climate impacts, while underrepresenting various indicators, including human toxicity, resource depletion, and circularity. Methodological limitations, such as generic datasets, a lack of performance-based functional units, and simplified EoL modeling, compromise comparability. Mechanical recycling often yields low-quality output with reduced performance, limiting reuse in high-value applications, whereas thermal and chemical methods face challenges in energy and scalability. Future efforts must prioritize standardized LCA methods, region-specific background datasets, circular economy integration, and advanced recycling technology to realize the full sustainability potential of FRP.
