公司工作人员有序将彩色覆盖物铺设在花境、树穴周围。红色环绕树干，黄色点缀草坪，与景观小品相 映成趣，让冬日公园瞬间鲜活。彩色覆盖物不仅美观，实用价值也很突出。相关负责人介绍，其可有效 抑制杂草、减少浇水频率，还能保温保湿助力树木越冬。同时，这一模式替代了焚烧、填埋等传统处理 方式，减少环境压力，形成资源循环闭环，助力绿色低碳城市建设。下一步，公司将继续推进绿化废弃 物资源化利用，扩大铺设范围，引导更多市民参与生态城市建设。 校对 陶善工 转自：扬子晚报 扬子晚报网1月9日讯（通讯员 周巧林 记者 张可）近日，南京大厂园林管养范围内多个公园广场、道路 岛头及树木树穴处，多了一抹抹鲜活色彩——由绿化废弃物加工而成的彩色覆盖物正式"上岗"。既为冬 日城市添彩，更实现了绿化废弃物循环利用。 冬季是绿化养护关键期，也是绿化废弃物产生集中期。经过粉碎、筛选、添加环保色素等加工，原本平 平无奇的绿化废弃物"华丽变身"为红、黄、绿等多种颜色的覆盖物。 ...

Core Insights - Beijing's municipal parks are increasingly utilizing green waste recycling methods to transform "green waste" into resources, improving sorting and transportation efficiency by 20% year-on-year due to the influence of the "Beijing Municipal Solid Waste Management Regulations" [1] Group 1: Waste Processing Techniques - Most municipal parks in Beijing are employing high-temperature composting to convert fallen branches and leaves into organic substrates, reducing secondary pollution from burning or landfilling [2] - The National Botanical Garden processes approximately 20,000 cubic meters of green waste annually, producing around 4,000 cubic meters of substrate, which saves about 1 million yuan in fertilizer costs each year [2] - Shredded green waste is rich in organic nitrogen, phosphorus, and potassium, improving soil structure and enhancing water retention and aeration [2] Group 2: Innovative Applications - Some parks are using shredded branches and leaves as biodegradable organic cover materials to enhance landscape aesthetics [3] - Baiwangshan Forest Park utilizes larger tree trunks for trail barriers and covers pathways with shredded materials, while all fallen leaves and weeds are composted back into the forest [3] - Yuyuantan Park combines green waste with ecological materials for landscape art, exemplified by the "Colorful Galaxy" garden using repurposed waste wood [5] Group 3: Future Directions - The Beijing Municipal Park Management Center plans to explore new pathways for resource utilization of green waste, collaborating with research institutions to develop high-value products such as organic fertilizers and ecological paving materials [9] - There are intentions to establish a closed-loop management model involving "parks-processing plants-urban green spaces," expanding services to surrounding communities and public green areas [9]
