“…Moawad, Zohdy, Badr, Khalafallah, and Abdel (1986) identify that the implementation of AD technology is an integrated sequence of processes, including waste management, digestion, and effluent and gas handling and usage. Successful development and management of AD technology require not only technical expertise but serious attention to economic and social issues, as well as human behaviours (Ni & Nyns, 1996).…”

Connections and relationships between conservation practices and community development in relation to rural sustainability have received considerable attention in recent years, especially in developing countries. Among many sound practices around the world, anaerobic digestion (AD) technology has long been encouraged as an alternative source of energy, while contributing to resource conservation and economic development initiatives in developing rural areas. Guided by the theme of sustainable development, the study examined the current applications of AD technology in Meiwan Xincun Village (MWXCV) in Hainan Province, China. Employing a self-administered questionnaire survey, face-to-face interviews and on-site observation, the study explored the diffusion process, current operation and local impacts of AD practice. The study identifies that leadership, education, technical support and local economy are key factors affecting the diffusion of AD, and governmental financial incentives are significantly effective measures to make the technology economically viable for local residents. The technology was found to fit into the rural livelihood system of the village, with considerable environmental and socio-economic benefits. Guided by the leaders of the village, the local residents generally accept and support the practice and are willing to contribute to introducing the technology in and out of the village. Suggestions regarding the utilization and diffusion of AD elsewhere are presented to enhance the potential capacity of the practice to generate benefits across rural Hainan.

“…Solid waste contains significant levels of nutrients necessary for plant growth, such as nitrogen, phosphorous, potassium, and organic matter. Therefore, when properly treated, it can be used as a soil conditioner and medium-grade fertilizer [16]. If solid waste from sewerage systems is properly sorted, it can not only solve the problem of its reduction and disposal, but also generate a lot of valuable resources.…”

Sewerage systems-related solid waste accumulates in considerable quantities in urban water systems, including rainwater drainage pipes, pumping stations, grease traps, grit chambers, and septic tanks. Traditional management methods, such as sanitary landfilling, incineration, and composting, not only endanger the environment but also consume a significant amount of land. To address this problem, a variety of waste was collected from a terminal and different facilities in sewerage systems, and the characteristics of solid waste were tested and analyzed. The corresponding appropriate approaches to resource recovery strategies were proposed in detail. The solid waste in the wastewater treatment plant (WWTP) contains low organic matter content and a certain quantity of heavy metals, making recycling difficult. Before the solid waste enters the WWTP, the strategy of pre-sorting, treating, and recycling the solid waste is worth recommending. The waste was divided into three categories based on its nature, and corresponding resource utilization strategies were proposed. A small part of solid waste that is not suitable for pre-recycling can be discharged normally and enter the WWTP for treatment. This paper provides a scientific basis for the green resource utilization of solid waste in the field of sewerage systems in developing countries.
