Residents’ desires to reduce food waste are significantly impacted by memories of famine. To explore the mechanism of famine memory on reducing food waste, this study included famine memory as a variable and developed an extended research model. Based on the survey of 384 valid questionnaires in Harbin, a structural equation model was employed to analyze the variables influencing the intention of residents to reduce food waste. This study found a significant positive relationship between residents’ intention to reduce food waste and their attitude, subjective norms, and perceived behavior control. Furthermore, attitude, subjective norms, and perceived behavior control were all positively and significantly impacted by famine memory. In addition, famine memory had significant indirect effects on food waste reduction intentions through attitude, subjective norms, and perceived behavioral control. We also examined the moderated mediation effects, found that gender and age had no significant moderating effect on the three parallel mediating effects. None earlier study has examined the effect of collective memory on reducing household food waste. By incorporating famine memory and simultaneously examining the mediating and moderating effects, this study created a unique theoretical model, thus supplemented the previous literature.

In addition, it advocates repairing PCCs that retain over 50% of their original size to extend lifespan and minimize waste. Deteriorated PCCs underwent dismantling, segregation, crushing, and grading to produce RCA. Mixes 1D1 and 1D2 use only NA for recycling and repair, respectively.

A cradle-to-cradle approach assessed economic and environmental impacts of 1-m PCC lengths across recycling and repair scenarios. Optimal mechanical outcomes in repair scenarios were achieved for mixes 1D2 and 2D2, resulting in 2.1% increased and 11.5% decreased compressive strength compared to conventional concrete (CC). Mixes 2D2 and 3D2 provided significant environmental benefits, reducing impacts by 38% and 41%, respectively.

In the present work, pyrolysis product components were taken into consideration along with char and oil as lumped parameters in a compartment model, and the kinetic constants for municipal solid waste two-step pyrolysis were identified based on a proposed simplified set of reactions. The experimental data were obtained from the process of two-step pyrolysis using Ni/ZSM-5 catalyst in a laboratory-scale reactor.

However, their resistance to degradation throughout the traditional life cycle—from production and consumption to disposal—leads to long-term accumulation of plastic waste in the environment. Over time, this results in the formation of microplastics and nanoplastics, which can persist for centuries. These particles contain chemical additives and also have a strong ability to migrate, posing significant ecological and human health risks. Despite increasing awareness of these issues, the recovery and recycling rates of plastic waste remain insufficient in many regions. This highlights the urgent need for effective analytical tools such as material flow analysis (MFA), which enables systematic quantification and tracking of plastic flows, stocks, and emissions across various stages of the life cycle. MFA offers valuable insights into the environmental fate of plastics and supports evidence-based policymaking for improved plastic management. With a growing number of international research applying MFA to plastics, it is essential for countries that have not yet engaged in such studies to understand the methodological framework, data demands, and policy relevance of this approach. This review provides a comprehensive synthesis of MFA applications at the national, regional, product, and material levels. It identifies current trends, methodological characteristics, and key findings in the field. Finally, future research directions are proposed to further enhance the role of MFA in addressing global plastic pollution challenges.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 4","pages":"2142 - 2161"},"PeriodicalIF":3.0,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
