- Construction Waste Treatment
In Chongqing, the treatment of construction waste is mainly through landfill and simple recycling, and the recycling rate is low. As of 2020, the reuse rate of construction waste in Chongqing is only 16.5%, and most of the waste is still processed through landfills. This not only takes up a lot of land, but also leads to a waste of resources ...

Use of prefabricated modules avoids more than 80% of total construction waste. Construction of a new house with prefabricated structure would save about 80–100 kg of waste per 100 m 2 floor area (Mália et al. 2013). Minimizing the quantity of raw materials stored onsite avoids double handling of material and waste generation due to damage.
