      City arduously exploring green waste recycling
      By:Zheng Qian  |  From:www.9918470.com  |  2019-04-11 12:55

      In recent years, public green spaces have sprung up in Chinese cities, beautifying the landscape. However, problems with withered leaves and branches have also come about. The two obvious solutions, burning and burying, are environmentally harmful and wasteful respectively.

      Shanghai has therefore made some attempts to systematically utilize green waste and process it into compost for lawns and gardens.

      In 2006, Shanghai built the first compost base for garden waste in Songjiang Xinqiao Nursery and essentially realized 100% utilization of the garden’s green waste for its  seedling nurture.

      According to Zhou Yizhong, deputy general manager of the Shanghai Jing'an Landscaping Development Company, self-developed technologies were applied in his company to smash and bio-ferment the fallen leaves into an organic medium. This material was then returned to the soil for the restoration of green land, efficiently solving the soil problems of insufficient fertility, hardening and a high PH value. Compared with other methods, this recycling processing has proved to be more environmentally friendly.

      However, the high cost has created a bottleneck in the city’s green waste recycling, with the compost base shutting down in 2015. And the Shanghai Botanical Garden Green Engineering Company, which is currently operating such a money-losing business and processing the largest amount of green waste in the city is actually “robbing Peter to pay Paul” for survival.

      In the view of Zhang Rui, the secretary general of the Shanghai Landscape Architecture and Gardening Trade Association, although the city has experience in green waste recycling, the relatively low recycling rate and the lack of suitable disposal sites in the downtown area are the major problems that need to be addressed in order to start a resurgence of green waste recycling.
