Summary: With the increase in urbanization and smart cities initiatives, the management of waste generation has become a fundamental task. Recent studies have applied machine learning techniques to predict solid waste generation, but it is challenging due to limited datasets and lack of important predictive features. In this research, an ensemble learning technique combining hyperparameter optimization and meta regressor model was developed to accurately predict the weekly waste generation of households in urban cities.

Summary: We built a comprehensive framework to explore the influence of psychological factors and food-related behavior routines on household food-waste behaviors. Online surveys were conducted in Beijing, Shanghai, and Wuhan in China, as well as Tokyo and Bangkok. We obtained a total of 3,000 responses. The results showed that compared to Tokyo and Bangkok, the proportion of people who always leave no leftovers when eating out was considerably lower in the three Chinese cities. Additionally, food disposal frequency was higher at the cooking and storage stages than at the eating stages when eating at home. The model analysis revealed that the intention of food-waste prevention was the most decisive factor affecting food-disposal behaviors when eating at home or eating out. Personal norm was the main driver of intention for food-waste prevention when eating at home, while subjective norm was the strongest predictor of intention when eating out.

Summary: The COVID-19 pandemic has had a significant impact on the Americas, particularly in Latin America. Strict lockdown measures during the pandemic halted recycling activities and increased plastic consumption as a means to prevent the spread of the virus. The lack of data on waste management dynamics has made it challenging to adjust waste management strategies to address COVID-19. This study used a virtual and participatory methodology to collect and generate information on household waste generation and composition, providing valuable insights into waste management during the pandemic in Latin America.

Summary: This study analyzed the waste sorting behavior of college students and found that on average, college students in campus environment disposed of 0.426 kg of recyclable waste per week, with higher drop-off frequency before classes and during meal times. Under the pressure of subjective norms, the majority of respondents reported a higher frequency of waste sorting than the actual situation. The current incentive level was found to have limited impact on regulating waste sorting behavior.

Summary: This study examines the economic and environmental effects of transitioning towards more circular food systems in the European Union (EU27) by feeding animals with low-opportunity-cost feed and better utilizing local feed resources. The results show that providing subsidies for circularity and promoting the use of low-cost feed can increase animal production, but also have negative impacts on land use and emissions. On the other hand, promoting domestic feed sourcing through import tariffs can decrease animal production and greenhouse gas emissions in agriculture. However, complementary policies are needed to mitigate drawbacks and enhance benefits of a more circular agri-food system.
