Environmental issues and management strategies for waste electronic and electrical equipment

Issues surrounding the impact and management of discarded or waste electronic and electrical equipment (WEEE) have received increasing attention in recent years. This attention stems from the growing quantity and diversity of electronic and electrical equipment (EEE) used by modern society, the increasingly rapid turnover of EEE with the accompanying burden on the waste stream, and the occurrence of toxic chemicals in many EEE components that can pose a risk to human and environmental health if improperly managed. In addition, public awareness of the WEEE or "e-waste" dilemma has grown in light of popular press features on events such as the transition to digital television and the exportation of WEEE from the United States and other developed countries to Africa, China, and India, where WEEE has often not been managed in a safe manner (e.g., processed with proper safety precautions, disposed of in a sanitary landfill, combusted with proper air quality procedures). This paper critically reviews current published information on the subject of WEEE. The definition, magnitude, and characteristics of this waste stream are summarized, including a detailed review of the chemicals of concern associated with different components and how this has changed and continues to evolve over time. Current and evolving management practices are described (e.g., reuse, recycling, incineration, landfilling). This review discusses the role of regulation and policies developed by governments, institutions, and product manufacturers and how these initiatives are shaping current and future management practices.

甲烷氯化物废水治理工艺的技术应用

在氯碱工业加工过程中会产生大量的甲烷氯化物废水,废水中含有大量的甲烷氯化物,该类废水不易处理,极大地影响了后续废水处理工作的开展。本文以某司甲烷氯化物具体试验为例,探讨高分子吸附剂在甲烷氯化物废水处理过程中的应用,在利用高分子吸附剂进行吸附的同时通过蒸汽吹脱使树脂中富集下来的甲烷氯化物得到分离回收,从而实现了废水的资源化,达到治废与资源利用的双重效果。     

Municipal solid waste management planning for Xiamen City,China: a stochastic fractional inventory-theory-based approach

In this study, a stochastic fractional inventory-theory-based waste management planning (SFIWP) model was developed and applied for supporting long-term planning of the municipal solid waste (MSW) management in Xiamen City, the special economic zone of Fujian Province, China. In the SFIWP model, the techniques of inventory model, stochastic linear fractional programming, and mixed-integer linear programming were integrated in a framework. Issues of waste inventory in MSW management system were solved, and the system efficiency was maximized through considering maximum net-diverted wastes under various constraint-violation risks. Decision alternatives for waste allocation and capacity expansion were also provided for MSW management planning in Xiamen. The obtained results showed that about 4.24 × 10⁶ t of waste would be diverted from landfills when p _i is 0.01, which accounted for 93% of waste in Xiamen City, and the waste diversion per unit of cost would be 26.327 × 10³ t per $10⁶. The capacities of MSW management facilities including incinerators, composting facility, and landfills would be expanded due to increasing waste generation rate.     

Public participation in municipal planning as a tool for coastal management: case studies from western Sweden

This article analyses four main models of participation in Swedish natural resource management and assesses strengths and weaknesses of one model (participation in physical/spatial planning) based on empirical studies of coastal resource conflicts in two Swedish west coast municipalities. In comparison to other administrative and planning procedures, physical planning offers possibilities to coordinate land and water management across sectors and resources and to broaden stakeholder participation. Local influence on coastal management increases with participation beyond the statutory minimum requirements, although management frameworks and practice of participation need to be developed further. Besides educating professionals and experimenting with combinations of existing procedures, in the long run an adaptation of legislation to the requirements of integrated and sustainable coastal management will be necessary.     

Environmental accounting on a communal level: A tool to support environmental management and decision-making by communal executives

Starting from an ecological perspective of urban-industrial areas, environmental accounting is used to analyse and to evaluate which environmental impacts are the result of communal activities (e.g. the results of different kinds of water supply systems). Therefore, the anthropogenic fluxes, the changing quality of areas as well as the processes between the environmental fields are taken into account. The approach is based on methodical elements of te Life Cycle Analysis and the Environmental Impact Assessment. Looking at the ‘urban systems’ within the communal activities, ‘ecological modelling’ gives us a new and fuller picture of the spatial and temporal character of urban metabolism. The approach supports the perception of cumulative effects and the postponement of environmental problems and opens new horizons for process-oriented environmental planning within the community. Greater efficiency and a decrease in costs can be arrived at by leaving ‘end of the pipe’ strategies; opportunities for a better planning process and measures for different individuals and organisations can be drawn up. A data base which acts as a ‘support system’ implements the computer-aided approach to environmental accounting.
