The primary objective of this research was to conduct a bibliometric analysis of recent literature on food waste, using Web of Science Core Collection and Scopus to identify gaps for future research projects especially on the field of food waste and sustainable food waste management. This approach allowed for a comprehensive assessment of the performance and efficiency of scientific research in this area. The use of both databases was a distinctive aspect of the study, as previous research has typically relied on a single database. The study analyzed publication trends between 2019 and 2024, focusing on highly cited documents, research areas, and keyword co-occurrence patterns, highlighting the growing relevance and importance of sustainability. In particular, there has been a significant increase in research published in environmental sciences, engineering, and energy fuels since 2020, reflecting the growing recognition of the role of food waste in reducing environmental footprints and enhancing energy efficiency and sustainability. The keyword analysis showed that between 2021 and 2023, the dominant themes were circular economy, sustainable development, development goals, supply chains, and life cycle assessments. More recent publications have shifted towards topics such as artificial intelligence, Sustainable Development Goals, empirical analysis, energy transition and green marketing. The research shows that the hospitality industry plays a crucial role in the sustainable food waste management, with effective strategies involving management practices, employee training, consumer behavior, and digital technologies offering both environmental and economic benefits. Further research is needed to explore the influence of cultural, institutional, emotional, and demographic factors, as well as the potential of circular economy models and platform-based solutions to enhance waste reduction and sustainability in different contexts.</div></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"11 ","pages":"Article 100318"},"PeriodicalIF":0.0,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144155060","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}

This study investigates household knowledge of CE and identifies key factors influencing its development by analyzing data collected from a survey conducted in Limpopo Province, South Africa. The research seeks to fill a critical knowledge gap by assessing the extent of CE understanding at the household level and identifying key factors that either facilitate or hinder its development. The findings reveal that 70 % of participants were unfamiliar with the term CE, and 72 % identified a lack of awareness as a significant barrier to its adoption. Nonetheless, 86.8 % of respondents exhibited a positive attitude toward waste sorting, reflecting an openness to CE practices. Income constraints were highlighted as a challenge, with respondents noting that limited financial resources hinder their ability to purchase eco-friendly products, which are often costlier. To address these gaps, the study recommends intensified awareness campaigns using diverse media channels to enhance household understanding and participation in CE practices.

This narrative review evaluates waste activation (pyrolysis) and CO₂ mineralization as solutions to repurpose Ghana's 12,710 tons/day of waste, with organic matter constituting 53.91 % of municipal solid waste, offering innovative solutions to these challenges. Drawing on global best practices and contextualizing them within Ghana's socio-economic and environmental landscape, the study examined the applicability, benefits, and implementation strategies of these advanced technologies. Key findings revealed that waste activation and mineralization mitigated pollution, reduced greenhouse gas emissions, enhanced public health, generated renewable energy and supported industrial growth. Studies show pyrolysis of low-density polyethylene sachets produces fuel with approximately 10 % lower global warming potential than conventional fossil fuels, while fly ash use in cement decreased CO₂ emissions by 15 million tons. The study also identified gaps in Ghana's waste management policies and provided actionable recommendations for integrating these technologies into the national framework. Notwithstanding growing academic attention to sustainable waste management, the specific roles of waste activation and CO₂ mineralization remain underexplored within the Ghanaian context. Existing policies and research continue to emphasize conventional approaches such as landfilling and incineration, offering limited empirical synthesis that aligns these advanced technologies with Ghana’s unique waste profile, institutional realities, and socio-environmental conditions. This review bridges this critical gap by critically examining the feasibility, benefits, and implementation strategies of waste activation and mineralization in Ghana, thereby contributing to innovative and contextually relevant waste management solutions. This research contributed to advancing sustainable waste management as a multidimensional framework, bridging environmental, social, and economic dimensions. Through linking global practices with local realities, the study offered theoretical insights and practical strategies for developing countries. Its novelty lies in its comprehensive examination of waste activation and mineralization within the Ghanaian context, introducing innovative pathways for waste-to-resource conversion and aligning with the Sustainable Development Goals (SDGs) and global climate objectives.</div></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"11 ","pages":"Article 100315"},"PeriodicalIF":0.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144155100","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}

This study applies a life cycle assessment (LCA) to evaluate waste management practices at a brake pad manufacturing SME in Mexico, using the IPCC Emission Factor Database (EFDB), the U.S. EPA’s WARM model, and the UK government’s conversion factors. While results show major discrepancies across tools, all agree on the climate benefits of recycling, reporting net reductions of –175.65 MTCO₂e for mixed metals and –24.77 MTCO₂e for corrugated containers. However, current models fail to fully integrate avoided emissions into official inventories, underestimating the role of circular strategies. To address this, the study proposes a hybrid methodology that combines scenario-based LCA with standardized emission factors, offering a context-adapted framework for emissions accounting in Mexico’s automotive sector. The research also highlights the importance of digital transformation (DT) and market orientation (MO) in shaping strategic responses among SMEs. While DT is often framed around technological adoption, this study underscores that market-driven strategies can enhance the effectiveness of environmental decision-making. By aligning MO with DT initiatives, firms can better adapt to regulatory pressures and sustainability targets.

Secondly, the fresh and hardened behavior of the fabricated mixtures were observed. Finally, the cost and environmental analysis were conducted to obtain a sustainability and cost-effective evaluation. The results proved that incorporating 10 % CCR boosts the hardened characteristics. In contrast, further upgrading the CCR content adversely affects the investigated responses. After 28 days, mortars incorporated with 10 and 50 % of CCR gave compressive strength of 31.6 and 20.4 MPa, respectively. Including 50 % CCR resulted in a maximum reduction in compressive strength of 35.4 and 29.6 % at 28 and 90 days of age. The cost and environmental analysis prove key advantages in lowering the equivalent embodied CO<sub>2</sub> emissions and the total cost of the mortar. The Incorporation of 10 % CCR lowered CO<sub>2</sub> emissions and cost by 9.6 and 6.8 %, respectively.

In combustion, both fuels increased brake-specific fuel consumption and emissions. Co-pyrolysis of waste oil and plastic has been shown to increase fuel yield and alkane content. The results suggest that co-pyrolysis offers an optimal waste management solution for Central Java, yielding higher fuel output (84 %) and lower metal impurities.
