Current Status of Manufacturing Hazardous Waste in Shanghai

It is difficult to manage the manufacturing hazardous waste (MHW) which is generated from a huge amount of compli- cated sources and causes very serious pollution. Therefore more and more attention has been paid to MHW pollution. Shanghai, as an industrial and economic center and an international metropolis in China, has a vast industrial system spanning a multitude of sectors, which generates MHW not only in a huge magnitude but also in a large variety of types from complicated sources, resulting in severe pollution. In 2003, the production of MHW in Shanghai is about 3.96 × 105 ton, involving 33 indices. Most of MHW in Shanghai is treated and disposed of, but a significant portion is not handled properly and effectively. This paper carries out in-field investigation on the current status of MHW production and treat- ment in Shanghai, and puts forward scientific proposals that Shanghai should facilitate cleaner production and minimize haz- ardous waste; strictly enforce hazardous waste registration system, strengthen monitoring the certified enterprises; strengthen intent disposal center construction and realize hazardous waste reclama- tion; accelerate establishing the technical criteria and the man- agement policy, promote the research and development on the treatment and disposal technology, and strengthen information management, thus realizing integrated management on MHW pollution.
