For example, Nantong municipal construction waste management regulations have formulated supporting provisions for the comprehensive utilization of construction waste.

The components of decoration waste in construction waste are complex, the sorting is troublesome and the utilization rate is not high. "We are using the original 2 construction waste yards to transform them into decoration waste sorting centers." Qian Xiaobing, deputy director of the Haian Urban Management Bureau, introduced.

In April last year, Wuhan was named and criticized in the Central Environmental Protection Supervision: "construction waste is illegally piled in low-lying areas such as fish ponds, flood storage embankments, and farmland, resulting in the decline of urban flood control and water logging prevention capacity.". Subsequently, Wuhan started the rectification, put the construction waste treatment and resource utilization on the agenda, put forward the principles of "emission reduction, standardized clearing and transportation, effective utilization, safe disposal" and "construction waste does not leave the area", and actively explore the disposal methods of environmental protection waste.

"There are some shortcomings in the utilization of construction waste materials in Hubei Province. Most of the construction waste is simply land filled, and even there is a phenomenon of illegal land filling." Hou Jiguang said frankly. According to the preliminary statistics of the Hubei Provincial Department of housing and construction, the annual output of all kinds of construction waste in Hubei is 82.833 million tons. By the end of last year, 40 construction waste disposal sites have been built in the whole province, and the actual annual treatment capacity is only 16 million tons, of which the utilization of resources is even less.

"As early as five years ago, we had made a detailed investigation on the disposal of construction waste materials in the whole province, and suggested that all cities establish resource-based disposal points, but with little effect." Hou Jiguang said that when reporting the treatment of construction waste, all localities always said that they had achieved a "balance between supply and demand", and there was no incentive or pressure to use resources. But in his view, this balance is just "spending money to landfill and pile up", and there is no illegal treatment.

"We are exploring to bring the recycling of construction waste into the franchise management, formulate the standards for renewable products of construction waste, and encourage the priority of renewable products." According to Hou Jiguang, the key to the resource utilization of construction waste lies in the government's leadership.

According to incomplete statistics, China's existing construction waste reaches 3.5 billion tons, and 1.5 billion tons of construction waste are added every year. In the next 5-8 years, the trend is still gradually increasing.

There is no garbage in the world, but the resources are misplaced

For every 10000 square meters of new buildings, 500-600 tons of construction waste will be generated;

7000-12000 tons of construction waste will be generated for every 10000 square meters of old buildings demolished;

By 2020, China will have an additional building area of about 30 billion square meters.

The scale of construction waste is amazing, which makes us not only enjoy civilization but also suffer from the "garbage siege".

Traditional disposal methods not only occupy land and pollute water resources, but also cause a waste of resources. Construction waste recycling has become an effective way to solve the problem of urban construction waste.

Turn construction waste into gold.

Where to go and how to deal with the demolished or abandoned construction waste?

The recycling of construction waste is a comprehensive project. We should start from the aspects of system construction, source control, technology research, concept change, and gradually establish a set of construction waste treatment system and technology that reflects "reduction, recycling, harmless, industrialization", so as to realize the recycling and industrialization of construction waste.

We should not worry about the place, the raw materials and the market for the products. Only a closed construction waste recycling treatment chain can be formed,

The road to the regeneration of construction waste can be unblocked.
