To reduce this food waste, interventions typically promote either food waste prevention or food waste recovery behaviours. These behaviours can be contradictory when it comes to shopping practices. Food waste prevention strategies suggest shopping for multiple days at once to benefit from planning and coordinate food packages with the needs of several days, whereas food waste recovery advocates for more frequent shopping trips to account for the unpredictability of everyday life. This study isolates the impact of shopping frequencies on food waste, assessing its effects across varying levels of uncertainties related to who will be present for dinner. A mathematical meal planning model is formulated to generate dinner meal plans and shopping lists by selecting combinations of recipes while considering nutritional adequacy and package sizes. The model uses a rolling horizon approach to simulate meal planning for household situations that are facing varying uncertainties in ingredient needs. As a base case, the model is run over a 21-day horizon for a household of four persons. The analysis reveals a trade-off between the flexibility of frequent shopping and the benefits of coordinating food purchases. Households with higher uncertainty in food requirements benefit from more frequent shopping compared to those with more stable needs, with total food waste across shopping frequencies ranging from 0–52 grams, 46–300 grams, and 50–900 grams per 21-day horizon for low-, medium-, and high-uncertainty household profiles, respectively. Moreover, the findings show that food waste can be minimized to 3 grams per day across all uncertainty levels by selecting recipes based on the food items already in stock at home. These insights suggest that tailored shopping and meal planning strategies based on household uncertainty levels can substantially reduce food waste and inform targeted interventions.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"57 ","pages":"Pages 403-412"},"PeriodicalIF":10.9,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144263475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we develop a framework to evaluate several decarbonization technologies and scenarios to achieve carbon-neutral cement production. A case study for Canada was conducted using this developed framework. Decarbonization technologies are grouped into six categories (energy efficiency, fuel switching, alternative raw materials, alternative binders and chemistries, carbon capture and storage, and cement carbonation) and each is evaluated using a bottom-up technology-explicit energy model. The results show that carbon-neutral cement production can be achieved before 2050 with marginal abatement costs of −17 to −34 CAD/t CO₂e and cumulative GHG emissions reductions of 199–242 Mt. CO₂e, based on a carbon price of 170 CAD/t CO₂ by 2030. The results are comparable to roadmaps from other jurisdictions but with some important distinctions. Canada continues to have a higher clinker/cement ratio and lower alternative fuel consumption than other jurisdictions, meaning carbon capture and storage is expected to play a larger role in reducing GHG emissions. Furthermore, carbon neutrality cannot be achieved without carbonation or a similar offset. Therefore, it is important that all cement-producing regions begin formalizing a framework to guide the calculation of carbonation impacts and compile the information to support those calculations. Finally, a sensitivity analysis concluded that carbon pricing is required in every carbon-neutral scenario to achieve negative GHG emissions abatement costs.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"57 ","pages":"Pages 355-374"},"PeriodicalIF":10.9,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144223523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially in the Global South, where a large part of the world's biomass is produced, vulnerable communities are at higher risk of being negatively affected by the bioeconomy. These risks include food insecurity, monoculture expansion, and unequal wealth distribution. Therefore, it is crucial to understand new bio-based value chains' (potential) social impacts better.</div><div>This paper contributes to this debate by developing a prospective Social Life Cycle Assessment (SLCA) for a bush-based value chain in Namibia.

We use this case study to reflect on the SLCA methodology and compare the SLCA results with our qualitative fieldwork based on interviews and a multi-stakeholder workshop. We found that the current methods for SLCA do not adequately capture salient aspects of the local context. SLCA is a good method to quantify some social impacts and to identify social risks in the value chain, such as labor conditions and existing policies. However, the methodology of SLCA currently misses a more nuanced understanding of the context and potential social issues, like issues related to gender and ethnicity, and the adherence to existing policies. We propose adding more context-specific indicators to the risk assessment. In addition, stakeholder engagement is crucial for identifying and assessing relevant social impact categories, and we advocate for incorporating local stakeholders' subjective assessments. This approach allows for the inclusion of softer social impact categories, such as gender and ethnicity-related social norms, which are not easily captured by general indicators.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"57 ","pages":"Pages 198-212"},"PeriodicalIF":10.9,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144195010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
