Special Issue Information

Dear Colleagues,

The purpose of this Special Issue is to provide crucial information to enhance discussions, analyses, and evaluations pertaining to the resource utilization of agricultural waste. It covers various research topics related to the technology of agricultural waste resource utilization, including pyrolysis technology, hydrothermal carbonization technology, biogas technology, and other relevant technologies. The increasing amount of agricultural waste due to the development of the agricultural economy poses a significant environmental impact if not properly managed. However, if agricultural waste is effectively and resourcefully utilized, it can be transformed into a valuable resource, such as renewable energy and series products. Authors are encouraged to submit their contributions on different hot topics in this field.

  • Characteristics, resources, and distribution of agricultural waste;
  • Pretreatment as well as thermochemical and biochemical utilization of agricultural waste;
  • Carbon capture, storage, and utilization of agricultural waste;
  • Extraction of value-added compounds from agricultural waste using green technologies.

Recently, there has been a significant focus on the issue of pollution caused by livestock and poultry rearing, which is recognized as a prominent contributor to nonpoint source pollution in the agricultural sector. This study employed the life cycle assessment (LCA) methodology to evaluate the environmental impact of several pig manure processing scenarios with the aim of determining the appropriate solid–liquid separation tool for large-scale pig farms. The findings indicate that the utilization of a screw extruder for solid–liquid separation in Scenario 2 has a lower environmental impact. In contrast to Scenario 1, Scenario 2 exhibits reduced environmental potential in the areas of global warming, human toxicity, acidification, and eutrophication. Specifically, the global warming, human toxicity, acidification, and eutrophication impacts decreased by 56%, 81%, 83%, and 273%, respectively, due to the implementation of solid–liquid separation. The type of solid–liquid separation equipment used during the processing of swine manure, as well as the subsequent treatment, have a significant impact on environmental emissions. Compared to Scenario 2, Scenario 3, which utilizes a centrifugal microfilter for solid–liquid separation, exhibits a lower environmental impact in terms of human toxicity, resulting in a reduction of 0.736 kg DCB-eq. In general, solid–liquid separation is a viable and environmentally friendly method for the disposal of waste from large-scale pig farms. The adoption of this method is highly recommended. During its implementation, careful consideration should be given to factors such as separation efficiency and pollution emissions. It is crucial to select appropriate equipment for solid–liquid separation to effectively process the waste. Full article
