位于礼贤镇的农业废弃物综合处理中心里，经过初步粉碎的秸秆、瓜秧尾菜等，通过传送带进入机器， 分别进入不同的处理环节，有的经过高温处理后进入巨大的好氧发酵池缓慢发酵，有的进入固化成型设 备压制成颗粒或方块…… 新京报讯（记者周怀宗）收获后的秸秆、遗弃的瓜秧尾菜、园子里的枯枝落叶……这些农业废弃物如何 处理？是否还有利用价值？又该如何利用？在北京市大兴区礼贤镇农业废弃物综合处理中心，这些原本 被当成垃圾的农业废弃物，通过晾晒、打碎、筛选、发酵、压制等不同工序，最终变成了宝贵的资源， 用作燃料、有机肥、各种添加剂的原材料。 负责人李俊山介绍，处理中心自2022年8月建站后至10月正式投产运行，建有好氧发酵肥料化、颗粒燃 料化、成型饲料化等多条生产线，现经过再次增加设备提升产能，达到年处理秸秆等农林废弃物4万吨 以上。 过去几年中，中国农科院环发所与北京市大兴区农业农村局建立紧密合作关系，以国家秸秆综合利用重 点区建设为依托，开展秸秆还田生态效应监测、秸秆尾菜资源台账构建和专题技术培训等，以科技助力 大兴区高效推进秸秆、瓜秧尾菜等农业废弃物资源化利用。中国农科院环发所副研究员、北京市生态循 环低碳发展创新团队岗位专家 ...

Group 1: Plastic Waste Management - China generates over 70 million tons of plastic waste annually, with a growth rate of 13%, but only about 30% is utilized, leading to significant environmental pollution [1] - The lack of efficient recycling technology for plastic waste has made its management a global environmental challenge, with the potential of waste plastics being likened to "solid crude oil" [2] - The market for recycled plastic utilization in China is estimated to be in the hundreds of billions, with conversion profits for high-end olefins being substantial [3] Group 2: Biomass Resource Utilization - The effective utilization of biomass resources is crucial for achieving carbon neutrality, with a focus on converting suitable resources into appropriate products [4] - The team has developed a rapid pyrolysis technology that produces high-purity humic acid from agricultural waste, establishing a large-scale production facility with an annual capacity of 200,000 tons [4] - Collaboration with agricultural machinery companies has led to the development of mobile pyrolysis units for on-site processing of crop residues, creating a closed-loop system for soil improvement [4] Group 3: Integration of Technology and Equipment - The core issue in waste resource utilization is the lack of integration between technology and equipment, which hinders the industrial application of laboratory technologies [5] - There is a need for government support in research and development of recycling technologies, as well as the establishment of industry standards [5] - Recommendations include allowing distributed, modular facilities to be built close to raw material sources to minimize risks associated with transportation and storage [6]

本报讯(张宣卢新怡)近日，太仓市举办农作物秸秆综合利用技术培训班，江苏省农科院资环所专家带来 的"肥料化、能源化、饲料化、基料化、原料化"技术，让农业废弃物秸秆实现"变废为宝"，为乡村绿色 发展注入科技动力。 在肥料化利用领域，资环所曹云研究员提出秸秆腐熟有机肥需遵循"有机无机合理配比"原则，通过有机 肥改善土壤结构、无机肥快速补充养分，实现改土、增产、提质多重目标。太仓市"一厂六中心"项目(1 个商品肥料厂+6个初腐熟处理中心)中，在资环所技术指导下，江苏省境博汇科技公司引入废气收集处 理系统，不仅解决发酵异味问题，还实现养分元素循环利用，让秸秆肥料化利用更高效环保。 培训班上，资环所农业废弃物资源化利用创新团队首席助理孙恩惠副研究员展示了以秸秆为原料研发的 基质块/盘原创成果，该成果可替代传统不可降解塑料秧盘，培育的秧苗符合水稻机插标准，既能提高 移栽效率、促进增产，又能推动秸秆循环利用；针对传统地膜污染问题，团队研发的秸秆基全生物降解 地膜，兼具环保、增温保墒、抑制杂草等多重功效，助力农业绿色转型。 据统计，太仓常年农作物秸秆超16万吨，可收集量超10万吨。2024年秸秆综合利用率已达100%，离田 率 ...
