Greenpeace East Asia investigated over 70 brownfield sites in Hong Kong during a period of 2 months and reported the findings in this documentation with heavy hearts: at least 35 brownfield sites covered over a total of 20 hectares (an area larger than the Victoria Park in Hong Kong) were found to operate in violation of regulations, piling up waste mountains up to 8 meters high. They were composed of huge amounts of waste from aluminium scrap, circuit boards to construction waste at open space workshops, leading to 7 heavy metals in soil exceeding standards.
