Construction Waste Management in Jinhua
On September 18, the Zhejiang Provincial Development and Reform Commission publicized the list of 2019 Provincial Resource Recycling Demonstration Cities. Jinhua ranked first among all 14 pilot cities with a score of 92.6 points.
Construction waste, including muck, spoil, mud, and other waste, is everywhere. In the past five years, more than 25 million tons of construction waste have been produced in the urban areas of Jinhua. Before, most construction waste was landfilled, not only occupying the land, but also polluting the soil, water, and atmosphere. Furthermore, the waste harms the environment during transportation. With the construction of the light rail project and the promotion of urbanization, we have seen a sharp increase in construction sites in Jinhua, with accompanying increase in construction waste.
Jinhua is one of the first 35 pilot cities of construction waste management in China. By the end of June 2019, Jinhua had completed 85% of the tasks for pilot cities. Turning the recycled construction waste into useful resources saves energy, reduces emissions, and promotes the development of industry in less developed areas.
“Every vehicle that transports construction waste is equipped with a spray to clean itself and a monitor to check if it's sealed once it is out of the construction site, to prevent the waste from polluting the road and to reduce the dust pollution. It's also the reason why the roads stay clean and tidy even though construction sites are increasing,” said a director from the Construction Waste Management Office of Jinhua. Now the construction waste discharge, transportation, and disposal in urban areas are all under close supervision.
Since 2004, the Jinhua Housing and Construction Bureau has issued several policies to improve the procedures for construction waste disposal. Now the construction projects in urban areas have to reinforce the main road and build protective walls before breaking ground. In addition, all the vehicles must be sprayed down before leaving the construction site to keep outsider areas clean. Those who have not implemented these measures or have only implemented them poorly will be punished and blacklisted.
“Construction waste is an important resource, and the recycling of construction waste reflects the principle of ‘from the building, to the building,’” said Yao Shuilin, president of Jinhua Construction Waste Disposal Association.
Every day, Mr. Chen from Shuguang Primary School has to go through Kangji Street to get to work. He still remembers that more than ten years ago, dust was flying everywhere along the street due to construction vehicles. Nowadays, although there are many large-scale construction sites such as City Light around Kangji Street, the residents nearby, teachers, and students are hardly affected by construction waste thanks to coordination among multiple departments and the management of construction waste.
