About this project
The composition of construction waste that created by different structures of buildings are different. However, their basic composition are the same, mainly composed of soil, muck, scattered mortar and concrete, masonry and concrete fragments produced by chiseling, reinforced concrete piles cut off by piling, scrap metal, bamboo and wood, waste materials produced by decoration, various packaging materials and other wastes.
Most of the construction waste is directly piled up in the open air or buried in the ground, which takes up a lot of land resources and produces dust and other problems, causing serious pollution to the environment.
