Construction waste "wind mouth" is rising, how to seize hundreds of billions of market space?
On July 1, 2021, the National Development and Reform Commission issued the "14th Five-Year" Circular Economy Development Plan, pointing out that the comprehensive utilization rate of construction waste will reach 60% by 2025, and the resource utilization of construction waste will become a "new market" for solid waste disposal under the background of "double carbon". The utilization of construction waste resources will become a "new market" for solid waste disposal under the background of "double carbon". It is understood that each comprehensive utilization of 1 ton of construction waste can reduce carbon dioxide emissions of 3.7 kg, recycled building materials can fill a huge material gap for the development of urban infrastructure.
Construction waste is divided into five categories: engineering soil, engineering slurry, engineering garbage, demolition waste and renovation waste, urban development, demolition waste and renovation waste is the industry's focus on the need to solve the problem, and whether it's demolition waste or renovation waste, brick and concrete category accounted for a high proportion of 75.80% and 55%, respectively, brick and concrete category of waste resource utilization usually includes crushing, screening, sorting and wind selection and other links.
The recycled products from demolition waste and renovation waste can be used for: aggregate, directly as road bedding materials, etc.; production of recycled bricks and other products, including aisle bricks, walkway bricks, etc.; and the production of more desirable products for various types of prefabricated parts.
In order to improve the utilization rate of construction waste resource utilization, China will build 50 construction waste resource utilization demonstration cities, and cultivate a number of construction waste resource utilization industry backbone enterprises. Dingbo Heavy Industry has also built a number of demonstration projects in various provinces and cities.
