Group 1 - The company has introduced colorful coverings made from processed green waste in various parks, squares, and tree pits, enhancing the winter cityscape while promoting recycling [1][3] - Winter is a critical period for green maintenance and the generation of green waste, which has been transformed into colorful coverings through processes like crushing, screening, and adding eco-friendly pigments [3][5] - The colorful coverings not only improve aesthetics but also serve practical purposes, such as suppressing weeds, reducing watering frequency, and providing insulation for trees during winter [5] Group 2 - This new approach replaces traditional waste disposal methods like burning and landfilling, thereby reducing environmental pressure and contributing to a resource recycling loop [5] - The company plans to continue promoting the resource utilization of green waste, expanding the coverage area, and encouraging more citizens to participate in ecological urban development [5]

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]
