Agricultural waste biomass resource utilization and its application in environmental remediation

With the increasing demand for energy, human beings need to find new renewable energy sources to promote human survival and development. The rational application of agricultural waste biomass is of great significance to reducing resource waste and improving environmental problems. This paper discusses the resource utilization of agricultural waste biomass and its application in environmental remediation. Agricultural waste biomass, such as crop straw and livestock manure, can be converted into efficient energy or biochar after resource treatment. This biochar has an excellent performance in soil remediation and wastewater treatment because of its high adsorption capacity. The preparation methods of biochar are diverse, including pyrolysis, hydrothermal carbonization, etc., and its properties can be further enhanced through physical and chemical modification. However, there are still some problems, such as low biomass utilization efficiency and unclear long-term impact on the environment. In the future, efficient biochar preparation and modification technology should be further developed to realize its wide application in environmental remediation.
