As the world's largest producer of construction waste, China's recycling and related policies are of the biggest concern to the world. However, the effective disposal and reuse of this waste has become an important issue since currently China still has a very low recycling ratio compared to developed countries, and most of the waste concrete was only simply broken and …

The construction sector is responsible for 39% of energy and process-related carbon dioxide emissions. This high percentage stems from actions on the construction site, transportation, and the manufacturing of building materials. Likewise, we should not forget about another critical factor for air pollution – dust from a construction site.
