摘　　要：广东农林废弃物资源丰富,推动农林废弃物多途径资源化利用符合国家节能减排、绿色循环发展的要求,也是广东城乡环境保护及治理的重大任务,对助力国家“双碳”目标也具有重要意义。本文综述了农林废物直燃/气化发电、制备沼气/绿氢、制备能源化学品及电化学应用等资源化利用工艺路径,解析了不同技术路径发展现状及存在问题,探讨了农林废弃物多途径资源化利用的发展前景,提出了促进农林废弃物资源化利用行业发展的建议。广东农林废弃物多途径高效资源化利用的发展,以期为实现我国“双碳”目标约束条件下生物质能源转型发展提供普适模型和理论支撑。Guangdong is rich in agricultural and forestry waste resources.Promoting the multi-channel resource utilization of agricultural and forestry waste conforms to the national requirements of energy conservation,emission reduction and green development,and is a major task of environmental protection and governance in urban and rural areas of Guangdong.It is also of great significance to help the“double carbon”strategy.This paper reviews the energy and chemicals production from agriculture and forestry waste resource via the technology route of direct combustion/gasification power generation,methane,green hydrogen,biodiesel fuel and methanol preparation as well as the electrochemical application.Also,the development and challenges of different technical paths are analyzed to reveal the utilization prospects of agricultural and forestry wastes resource.Finally,we propose suggestions to promote the development of agriculture and forestry waste resource utilization.It is expected to provide a universal model and theoretical support for the conversion and development of biomass energy under the constraint of“carbon peaking and carbon neutrality”goals,promoting the multi-channel efficient resource utilization of agricultural and forestry wastes in Guangdong.
