Solving e-waste problem using an integrated mobile recycling plant

• E-waste problem is solved with environmental improvement and resource recycling.
• Environmental performance and ecological efficiency are identified in detail.
• Integrated mobile recycling plant is effective to solve e-waste problem.

The proliferation of toxic electrical and electronic waste (e-waste) have become problematic, especially for small countries or cities with extremely high population densities. Environmental pollution and resource discarding have been widely recognized in case of temporary stock, simple dismantling, landfill or transboundary transportation of this waste. To address these e-waste problem subjected to environmental conservation and resource recycling, we designed an integrated mobile recycling plant, operating with combined processes of dismantling, crushing, and multi-level separation. Two large standardized and movable containers were equipped for whole-unit dismantling as well as waste monitors and printed wiring board recycling. A sophisticated demonstration indicates that valuable resources, including metals, plastic and glass, could be fully separated for further recycling. Meanwhile, we evaluated the environmental performance from the perspectives of gaseous emissions, waste water, and noise pollution, and found that these emissions could completely meet the requirements of environmental protection and human health. In addition, ecological efficiency assessment revealed that integrated mobile recycling plant could solve e-waste problem for small countries or cities.
