SHANGHAI - East China's metropolis of Shanghai has seen 90 percent of housing estates compliant with the mandatory garbage sorting regulation in effect since July 2019, said Ying Yong, mayor of Shanghai on Wednesday.

While delivering a government work report at the opening of the local annual legislative session, Ying said that with the comprehensive garbage collection and transportation system built up in 2019, the city's daily amount of recyclable waste increased by 431.8 percent year on year, that of wet waste increased by 88.8 percent, and that of hazardous waste increased by 504.1 percent.
