Constructive use of construction waste
Shanghai is trialing the resource utilization of different types of construction garbage, and reusing discarded wood, paper, brick and stone, a senior official with the city's greenery authorities said.
The city produces about 100 million tons of construction waste every year, compared with just 22 million tons in 2006.
Xuhui, Songjiang, Jiading and Jinshan districts and the Pudong New Area have established resource sorting terminals and treatment facilities of construction waste, said Lu Yuexing, director of the Shanghai Greenery and Public Sanitation Bureau, adding that construction had started in Minhang District for a similar facility.
"Wood and paper can be converted into fuel rods after being sorted, while bricks and stones will be used for road pavement," said Lu. Construction garbage is also used for landfill.
The resource utilization facilities will be set up citywide, according to Lu. Currently, construction garbage sorting venues have been set up citywide, but most districts are still using manual sorting.
Mechanized sorting will be gradually promoted and standard sorting and treatment procedures will be established, said Lu. Shanghai has banned the transportation of construction wastes to other cities.
The city has also improved management on construction sites, demolition units and property management companies with regard to the reporting of construction garbage sources and enhanced the reporting platform of construction waste.
