The birth of an emerging industry: urban construction waste treatment and recycling
Source: Number of views: 2362

       Green water and green hills are Jinshan and Yinshan. At present, China attaches great importance to ecological and environmental issues. Construction waste occupies about 40% of the total amount of urban waste. A large amount of construction waste is transported to suburbs and open dumps without any treatment, causing greater pollution and damage to the natural environment. How to deal with construction waste? As a senior employee of Chongqing Crostro Environmental Protection Technology, the editor briefly shared the treatment and recycling of construction waste.


        1. What is included in construction waste?
        Among a large number of construction waste, including concrete blocks, asphalt blocks, waste residues, waste metals, waste plastics, decoration waste, packaging materials, etc.
        2. Emerging industries of construction waste recycling
        During the "Twelfth Five-Year Plan" period, China has placed the construction waste recycling industry as an emerging industry in a relatively important position, and issued "Several Opinions on Further Strengthening the Management of Urban Planning and Construction", pointing out that construction waste should be established. Recycling and recycling system, while the Ministry of Construction issued a document clearly pointed out that it is necessary to strengthen the promotion and use of green building materials, strengthen the research and development of recycled building materials technology, and improve the quality of solid waste products.
        3. Innovative development of construction waste treatment equipment
        In order to research and develop construction waste disposal machinery and equipment suitable for different regions of China, many large domestic machinery manufacturers have successively borrowed and developed the country's waste sorting and treatment technology, and innovatively withdrew from a variety of mobile crushing and screening equipment. Chongqing Crostro Environmental Protection Technology has successfully launched a variety of tire-type mobile crushing stations and crawler-type mobile crushers.
        4. Utilization of construction waste
        Construction waste must be sorted out first, and this is where mobile crushing and crushing stations provide screening. At present, the recycling and utilization of construction waste in China are mainly divided into two categories, one is to make blocks and bricks for construction, and the other is to make construction aggregate, which is divided into coarse and fine materials. The recycling of construction waste to make recycled building materials is currently a relatively common method of utilization. In addition, a lot of construction waste is construction concrete and construction muck. These muck can be recycled to make bricks, and some abandoned construction bricks can be added with some auxiliary materials to make lightweight blocks. Waste materials such as waste cement, sand, glass, etc. can be made into hollow block bricks, hollow partition boards, porous bricks and other building materials through professional processes, and can still be used for construction engineering again.
        Because construction waste is mainly solid waste, these solid wastes can be crushed and reused, and after crushing, they can be made into some aggregates for industrial and construction engineering construction. Aggregates can be divided into coarse aggregates and fine aggregates. Coarse aggregate is generally used to make concrete for construction, which can be used for foundation reinforcement and road maintenance. Fine aggregate is generally used for masonry mortar.
        V. Strong support from relevant departments
        At present, the utilization of construction waste resources has been highly valued by relevant departments, and a series of documents and regulations have been issued to provide some corresponding preferential policies for the expansion and rapid development of construction waste resources enterprises, and encourage private enterprises to strengthen their operations to Scientific systems and regulations improve the recycling rate and utilization rate of construction waste. At the same time, a pilot city of construction waste has also been established, which has provided lessons for construction waste recycling and utilization in many areas. Relevant departments have also introduced preferential policies to encourage thoughtful individuals and enterprises to strengthen technological innovation and R & D, and gradually establish an industrial chain of construction waste treatment and resource utilization, thereby achieving the green and environmental protection of construction waste.
        In summary, the utilization of construction waste is an emerging industry. If you have the idea to join the industry, you can contact the Kross Environmental Protection Technology Co., Ltd. of Chongqing Longjian Group to purchase mobile crushing stations and enjoy market dividends to green the motherland Great rivers and mountains contribute a lot!
