Special Issue Information

Dear Colleagues,

I would like to take this opportunity to invite you to participate in a Special Issue titled “Waste-to-energy challenges for the valorization of industrial wastes”, which is to be published in Processes. Processes (ISSN 2227-9717; Impact Factor: 2.847) is an international peer-reviewed open access journal on the processes that take place in the chemistry, biology, materials, energy, environmental, food, pharmaceutical, manufacturing, and allied engineering fields.

In recent years, there has been a surge in demand for non-renewable energy sources, such as fossil fuels, nutrients such as nitrogen and phosphorus, chemicals, etc. These are natural resources that cannot be replaced once they are consumed, which is a major concern these days. Alternatively, industrial wastes are potential sources of energy and high value-added products. The amount of waste that is dumped in landfills has been growing at alarming rates due to the limited number of sites and the creation of greenhouse gas emissions. Additionally, residue from crop production and processing, manure from animal production, and wastewater from industrial and municipal sources all contain waste organic matter, which can be converted to valuable products. Therefore, developing innovative processes in existing facilities offers an economical and versatile way for resource and energy recovery from various waste streams.

This Special Issue on waste-to-energy challenges for the valorization of industrial wastes highlights the current trends and future perspectives for waste valorization and resource recovery.

Potential topics include but are not limited to the following:

  • Biological wastewater treatment;
  • Anaerobic digestion;
  • Microbial electrochemical technologies;
  • Production of biochemicals, bioenergy and bioproducts from various waste;
  • Nanobiotechnology;
  • Biomass conversion into renewable fuels;
  • Soil Bioremediation;
  • Solid waste management;
  • Biorefinery;
  • Sustainable processes for waste management;

As one of the basic industries in the manufacturing industry, the modeling and evaluation of resource utilization efficiency in the machining process is the premise of energy conservation and consumption reduction in the manufacturing industry. Mechanical processing is the process of using resources to change the shape and performance of the blank to form the workpiece and generate emissions. However, the current research on the utilization of machining process resources, whether focusing on energy efficiency or emissions, cannot provide a comprehensive solution to this problem. Therefore, this paper proposes a Data Envelopment Analysis (DEA) model with a slacks-based measure (SBM) to evaluate the resource utilization efficiency of a machining process with non-expected output. Through the relative effectiveness of DEA, the resource utilization efficiency of each processing process can be compared, which can provide a feasible and specific method for enterprises to evaluate their existing processing processes from the perspective of reducing unexpected output. In this case, the input-output model of the machining process is used to analyze the processed resource list. Then the mathematical model of each process in the processing process is established, and the dynamic resources are determined quantitatively. Finally, the accuracy of the method is verified by combining the resource utilization efficiency of each working procedure in the shaft gear machining process of an enterprise. Full article
