The impact of pollution caused by a 700-hectare landfill in Cu Chi District, HCMC, extends up to 10 km, affecting the lives of thousands of people residing in the vicinity. This landfill, which is the largest in HCMC, receives more than 3,000 tons of garbage daily. Currently, there are two waste treatment companies operating at the landfill, employing outdated methods such as burying or burning trash that cannot be recycled. Unfortunately, these methods contribute to the pollution of the surrounding area.
