In 2017, the Chinese government created a policy on mandatory waste separation. Many communities and cities have created waste management institutions and appointed workers to supervise these actions. But there is little information about the situation in terms of the knowledge, attitudes, and practices of waste separation and any differences among regions and cities. Thus, the goal of this paper is to show the current status quo and any differences and to analyze their determinants, especially regarding cultural consumption. Based on online survey data collected in 2021, we found that knowledge in rural regions was lower than in urban regions, but there was no difference in attitudes or practices; the practices in pilot cities were better than in non-pilot cities, but the knowledge and attitudes showed no differences. Different cultural consumption patterns had different impacts on waste separation knowledge, attitudes, and practices. Based on the results, a policy related to culture should be enacted to improve efficiency and increase the action impacts to solve environmental and social issues.

Abstract The study aims to analyze the factors affecting community involvement in the waste separation and reduction through waste bank for low participation through benefits offered to its member. Logistic regression was used for the analysis, and there were 26 dependents variables applied to the analysis. The result showed that six variables, i.e., age, occupation, participation in social activities, knowledge of sustainable development, distance from HH to WB, and availability of dissemination of 3R, affect people’s motivation to be member and actively involved in waste reduction through the waste bank. All variables except distance are proportional to the motivation of the community to participate in waste bank. The attained model is used to calculate the probability of community participation in waste banks afterward. Using different conditions, where variables are set with values of zero and one representing absence and availability of related variables, respectively various probability values come out ranging from 0% to 94.8% which is the highest probability value if all significant factors are available.

Waste source separation has been a social dilemma globally with a low participation rate. This research attempted to solve this dilemma by exploring the effect of mandatory (versus voluntary) policies on waste separation from the perspective of the self-versus based on deterrence theory and self-enhancement motivation. Hypothetical scenarios were used to demonstrate the effectiveness of mandatory policies and self-enhancement bias for residents (n = 589) and adolescents (n = 121). Study 2 was performed to replicate the findings of Study 1 with a no-implementation policy condition, and Study 3 extended the findings to adolescents. We found robust self-enhancement bias, where participants perceived themselves to be better than others in both willingness to perform and attitudes toward waste separation behavior. Specifically, participants tended to perceive themselves to perform waste separation well when policy compliance was voluntary, but they tended to perceive others to perform well when policy compliance was mandatory with supervision. These findings highlight the impact of mandatory policy with supervision and self-enhancement bias in waste management. The present studies provide substantial evidence and implications for the necessity of supervision in mandatory policy implementation.

College students are the engine of the sustainability of the future, and their awareness of environmental protection and waste classification is very important for the sustainable implementation of urban solid waste separation projects. Chongqing is one of the first 46 waste separation pilot cities in China. The primary objective of this study was to investigate the municipal waste separation behavior of college students and its influencing factors. Data from a total of 814 questionnaires among college students from sixteen universities in Chongqing were collected. Results showed that most college students think it is necessary to separate waste, and they have executed it in their daily life. Students have a high accuracy in classifying perishable waste, but they are not familiar with the classification of waste lamps, bulbs (14.00%), expired drugs (30.71%), toilet paper (11.3%), peel (18.80%) and brick kilns (27.76%). Special attention should be paid to distinguishing recyclables and other wastes. The principal factors that affect students’ willingness to classify waste are attitude, situational factors and publicity and education, which are embodied in students’ attitude towards waste separation, the surrounding environmental hygiene, the convenience of waste separation, the ease of understanding of waste separation marks and the degree of publicity and education of the school. Four measures are recommended for improving students’ willingness to separate municipal waste based on this investigation.

<p>Food waste presents a resource management challenge for New Zealand communities, businesses and governance institutions. The energy, labour, soil, water and myriad other inputs used to grow, manufacture, distribute and prepare food are lost with each kilogram that is thrown away. Numerous technologies enable the energy and nutrient potential within food waste to be recovered. Systems of this type are most efficacious when food is separated from other waste streams at source. This research demonstrates that New Zealand‟s existing waste related legislation has the potential to foster market conditions favourable to food waste recovery initiatives and technologies. However, the suite of policy instruments currently actuated provides weak stimulus for the adoption, innovation or expansion of food waste diversion ventures amongst stakeholders. Current legislation does little to incentivise food waste separation within hotels. Many hotel operators are reliant upon third party provision of waste collection, recovery and or disposal services. Exceptions include operators for whom onsite food waste processing systems or arrangements with individual farmers (who collect waste at low cost) are viable. Within this thesis, food waste, the New Zealand tourism product and the environment‟s capacity to assimilate waste are conceptualised as common pool resources requiring interconnected management regimes.</p>
