Currently, construction waste is one of the more difficult types of municipal solid waste to handle, with large and concentrated quantities. It is predicted that the annual volume of construction waste generated in Beijing during the 14th Five-Year Plan will reach more than 130 million tons.
Construction waste includes trenching earth, sand and gravel that can be used directly, as well as engineering waste and demolition waste that need to be disposed of and reprocessed, and decoration waste that needs to be sieved and disposed of, each with different composition and disposal methods, but all with high utilization value. It is necessary to implement the classification and disposal of construction waste to further improve the efficiency of utilization.
In order to further promote the classification and disposal of construction waste in Beijing and the comprehensive utilization of resources, recently, the Beijing Municipal Urban Management Commission and other 10 departments jointly issued the "Opinions on Further Strengthening the Classification and Disposal of Construction Waste and the Comprehensive Utilization of Resources" (hereinafter referred to as "Opinions"), which proposes to comprehensively encourage assembly-type construction, actively promote steel structure assembly-type housing, as well as factory prefabrication, assembly construction In addition, the construction model will be managed with information technology to minimize the production of construction waste.
According to the "Opinions", Beijing will be in accordance with the resource class and disposal class of construction waste for classification and utilization or disposal. Resource class construction waste, including engineering residue, engineering mud, by the producer unit in accordance with the "market-led, appropriate regulation" principle of implementation of the use; disposal of construction waste, including engineering waste, demolition waste and decoration waste, requiring producers to bear the cost of disposal, to encourage the implementation of local disposal, can not be disposed of locally should be selected in accordance with the principle of proximity Resource-based disposal facilities for disposal. It is strictly prohibited to mix household garbage and hazardous waste into construction waste.
For the disposal of various types of construction waste, "Opinions" states that
The implementation of direct use of engineering sludge, priority for land reclamation, soil improvement, greening landscaping and pit restoration and other ecological construction and restoration projects, trenching sand and gravel by the construction waste resource-based disposal site processed into recycled sand and gravel materials before use.
Engineering mud to take in situ resource-based disposal to implement the treatment, can not be disposed of in situ, after drying and engineering residue synergistic use.
The metal discarded materials in the project garbage are directly reused in the project, and the inorganic non-metal discarded materials are processed into recycled building materials for resourceful disposal.
demolition waste to encourage the setting of temporary construction waste resource-based disposal facilities for disposal.
Renovation waste generator entrusted to others to dispose of renovation waste, should bear such disposal costs. Entrusted units can be based on the actual, clearly marked price to take "by bag", "by car" or "by weight" and other ways to charge the generator fees.
In the comprehensive utilization of construction waste resource, "Opinions" proposed to promote the construction of construction waste resource disposal facilities.
Construction waste resource-based disposal facilities are refined and adjusted to in situ disposal facilities, temporary disposal facilities, fixed disposal facilities, all kinds of facilities set up and operation should meet the requirements of the relevant national and municipal standards. Encourage qualified construction units, construction waste screening, crushing production line within the red line of the project, the implementation of construction waste disposal in situ, the disposal facilities should be dismantled and restored to their original state before completion.
In addition to the core area, each district should have no less than 2-3 fixed (or temporary) disposal facilities. Temporary disposal facilities should obtain the consent of the district planning and natural resources department, dust control measures should be in line with ecological environmental protection requirements; with conditions in accordance with the "Beijing Municipal Urban and Rural Planning Regulations" requirements for the relevant planning procedures, the set-up period should not exceed 3-5 years; fixed disposal facilities construction should be incorporated into the municipal infrastructure construction planning, facilities should obtain planning and environmental impact assessment permits.
