Treatment, Recycling, and Utilization of Secondary Resources

Dear Colleagues,

Secondary resources are important components of municipal solid wastes, primarily comprising plastics, metals, electronic devices, and organic waste. By effectively developing and utilizing these secondary resources, it is possible to mitigate environmental pollution from waste, reduce resource consumption, foster the development of a circular economy, and achieve sustainable resource utilization. For instance, organic matter can be sorted, processed, and converted into auxiliary coal fuels or biogas and high-quality fertilizers through microbial degradation. Additionally, discarded electronic devices contain reusable materials such as metals, plastics, and glass, which, through recycling, can reduce the demand for natural resources and extend their utilization cycle. Therefore, advancing the treatment, recycling, and resource utilization of secondary resources in municipal solid waste is essential for environmental sustainability, efficient resource utilization, energy efficiency, economic development, and reducing waste emissions.

In this Special Issue, both original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Characteristics of secondary resources (e.g., spent batteries, minerals);
• Secondary resource treatment technologies;
• Recycling and resource utilization;
• Materials from secondary resources;
• Environmental impacts.

We look forward to receiving your contributions.
