The government should further supervise and control hazardous waste discharged by enterprises and enforce drainage information disclosure regulations, experts said in response to a recent landfill scandal in Beijing.

KB (Beijing) Autosys Co Ltd, a South Korean company that produces auto parts in Miyun county, dumped hazardous waste directly on farmland and in forests for three years, seriously polluting the soil and air of surrounding villages.

Instead of disposing of the waste properly, the company simply dumped it in about 30 holes, the average diameter of which was 30 meters.
