The management of municipal solid waste (MSW) in China is facing urgent problems with rapid industrialization and urbanization. This article focused on the status of Hangzhou, capital city of Zhejiang province, China. The regulations, policies, implementation, barriers and solutions about source separation, separate collection, clean & direct transportation, treatment and disposal were introduced. Source separation, separate collection and clean & direct transportation were seriously carried out from 2010. MSW was classified into four kinds, such as kitchen waste, hazardous waste, recyclable waste and other waste. Four kinds of wastes were collected, transported, treated and disposed, respectively. At the same time, a questionnaire survey was conducted in 2011 on 200 households in Xiasha and Gongshu Districts in Hangzhou. The results indicate that many citizens cannot effectively and correctly separated different kinds of solid wastes. Kitchen waste was directly disposed in landfill, because there is no composting plant in Hangzhou City. The collection of recoverable waste and hazardous waste was not in control of municipal solid waste management (MSWM) system. In order to optimize MSWM system in Hangzhou, the government and the citizen must make efforts in source separation, comprehensive treatment system, effective regulations and policies.

Source separation plays a pivotal role in sustainable and integrated Municipal Solid Waste Management (MSWM) and in achieving a circular economy in Asia. However, it is still not an official practice, and many cities continue to utilise open dumping, involving receiving mixed waste without pre-treatment. This paper, therefore, examines the advantages of source separation of MSW and explores the main factors for success in the planning and implementation of official source separation programmes in cities in Asia. Analysis of the results for two case studies in India and Japan could be used to strengthen capacities of policymakers in designing and implementing official source separation systems to facilitate material recovery and achieve sustainable development in Asia.

Waste Management Practices

This paper presents an overview of the current solid waste management practices in Gashua town and provides a brief discussion on future challenges. Gashua town the headquarters of Bade Local Government Area since 1949. Since then the population has mainly due to the influx of people and its strategic location along the axial route to significant towns in the state. Wastes are generated mainly from residential, commercial and institutional land uses. Waste collection sites are strategically situated as identified by the agency and designated as high waste generating points, metal waste bins and constructed waste bunkers. The contents of these bins are finally disposed of at a location 6kilometres away from the generating points. Spatial data on waste distribution was collected using a global positioning system (GPS). The data was manipulated and processed using a Geographic information system (GIS) to produce the waste distribution map. Findings revealed that the existing solid waste management system is inefficient as the present practice relies on monthly collection and disposal of waste using an open dumpsite.

Abstract Household solid waste management (HSWM) practices are a critical aspect of municipal solid waste management (MSWM) systems. Despite efforts to implement source separation and recycling at the household level in developing countries, negative practices such as illegal dumping and backyard burning remain ubiquitous, particularly in rapidly urbanizing cities. Source separation and recycling behaviors have been rarely studied in such cities. Moreover, studies on illegal dumping and backyard burning using robust tools and frameworks are practically non-existent. This study aims to (a) estimate the prevalence of “negative” and “positive” behaviors for different HSWM practices, and (b) identify their observable and non-observable influencing factors. The focus is Santa Cruz, a rapidly urbanizing city of Bolivia. Household surveys (n=305) are used to establish the connections between latent constructs (e.g. awareness, satisfaction), and observable variables (e.g. location, socio-demographic characteristics) with each behavior. This is achieved through the combination of exploratory factor analysis to validate the constructs to be included in the analysis, and structural equation modeling to identify the most influential factors. Two causal models are developed, one for the positive behaviors (i.e. source separation, recyclables donation, recyclables selling, and use of drop-off facilities), and the other for the negative behaviors (i.e. illegal dumping and backyard burning). Results indicate that, satisfaction with the MSWM service has a negative and significant influence on the prevalence of illegal dumping and backyard burning behaviors, while the remoteness of the household (i.e. distance to the city center) has a positive significant effect on the prevalence of these behaviors. Source separation and recyclable donation are influenced positively by latent constructs such as attitudes, knowledge, and awareness. For recyclables selling and use of drop-off stations, income and location are the most relevant factors, although with smaller effects.
