However, food consumption behavior is highly heterogeneous and depends on numerous variables, including affordability and availability of different food categories and products. The main objective of the current study was to analyze changes in GHG emissions linked to Peruvian dietary patterns and analyze their geographical and temporal variability, using household survey data for the period 2008–2022. From a methodological standpoint, the model estimated apparent household food consumption, as well as food away from home, food obtained from charities, and food loss and waste quantification, to provide an in-depth depiction of Peruvian diets. Diets were then estimated based on geographical location, socioeconomic groups, and the Peruvian average diet. Results show that GHG emissions have remained stable during the period analyzed (1126 kg CO<sub>2</sub>eq/person/year on average), with a peak attained in 2014 (1236 kg CO<sub>2</sub>eq/person/year) after years of economic growth and substantial decreases in the poverty rate. Thereafter, carbon emissions have dwindled based on increasing poverty levels, and a gradual substitution of beef for chicken meat, although heterogeneous patterns can be observed among regions. It was estimated that by 2022 an additional 1401 kt CO<sub>2</sub>eq per year would be emitted to guarantee that those living in poverty or extreme poverty conditions reach daily minimum caloric requirements. The uncertainty of the results, a comparison of these to those of other countries around the world, and potential improvement actions to attain healthier low carbon emission diets are also discussed.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"29 ","pages":"Article 200305"},"PeriodicalIF":6.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145924759","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}

We identify sustainable value created and captured by different stakeholders and identify how resources and capabilities influence value creation processes along the value chain. We further explore how value proposition, value creation and delivery, and value capture, along with key barriers and drivers, influence the adoption of large-scale carbon mineralization.

The approach integrates a custom-built smart kitchen scale with a mobile application and a cloud-based portal. The system guides participants through daily waste recording by automatically capturing weight data and allowing users to categorize discarded food by type, avoidability and disposal method. All data is transmitted in real time to a centralized platform, ensuring consistent, high-quality data with minimal user effort. The toolset supports field campaigns involving hundreds of households over a defined period (e.g., one week), improving standardization and reducing reporting errors. The method can be seen as an enhanced form of direct measurement, combining the accuracy of weighing-based approaches with the efficiency of digital tools. A pilot study confirms the system’s feasibility, participant acceptance and ability to generate detailed, comparable datasets suitable for food waste reporting at different levels.

The technical analysis reveals that adding two components (recycled aggregates and LDPE) decreases thermal conductivity and density by 56.8 % and 32.6 %, respectively. Second, mechanical resistance is lower than that of more conventional solutions, suggesting that the new product is suitable for non-structural applications while improving the thermal resistance of construction systems. The economic analysis, using simulation tools (FlexSim), shows that one component decreases the cost per cubic metre and transportation costs per unit, while increasing the break-even time, ultimately shortening the period required to reach profitability. The environmental analysis conducted via life-cycle assessment (LCA) positions products made with one of the components―recycled ceramic aggregate―as the most environmentally friendly, with a 16.8 % reduction in GWP compared to other solutions.

Empirical research on the psychological drivers of DRS participation remains limited, especially in Central and Eastern Europe, creating a need to understand how attitudes shape behavioral adoption in early-stage systems. This study applies the three-component attitude model, distinguishing cognitive, affective, and conative dimensions, to explain consumer participation in Hungary’s newly introduced national DRS, the REpont scheme. Unlike most previous applications, the model was identified inductively from empirical data through exploratory and confirmatory factor analyses, providing a data-driven theoretical contribution to behavior research. A large-scale survey (<em>n</em> = 2665) was conducted and analyzed using partial least squares structural equation modeling (PLS-SEM). The findings indicate that affective and conative attitudes are strong predictors of system use, while cognitive evaluations exert a moderate but significant effect. For the latter, however, demographic and cluster analyses revealed subgroups (urban, highly educated) with reduced usage despite higher awareness. Emotional commitment strengthens favorable evaluations, which in turn encourage behavioral intentions and routines, confirming the sequential pathway from affect to cognition to conation. From a theoretical perspective, the study extends the attitude model to a novel circular economy context, while from a policy and managerial perspective, it highlights that addressing infrastructural barriers and contextual challenges and strengthening emotional engagement are essential to ensure the long-term effectiveness of DRS.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"29 ","pages":"Article 200299"},"PeriodicalIF":6.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145580124","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}

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}
