by Develop precast buildings and encourage full decoration delivery! In recent years, with the rapid development of urbanization in China, a large number of construction waste has been produced.
According to calculation, the annual output of urban construction waste in China exceeds 2 billion tons, which is about 10 times that of domestic waste, accounting for about 40% of the total amount of urban solid waste.
Construction waste has become the largest and most concentrated solid waste in China.
At the same time, China’s construction waste is mainly treated by outward transportation, landfill and open stacking, which not only occupies a lot of land resources, but also causes groundwater, soil and air pollution, endangers the ecological environment and people’s health, and seriously affects the coordinated development of social economy and ecological environment.
The problem of treatment and utilization of construction waste needs to be solved urgently.
With the transformation and upgrading of green construction and construction industry, the reduction of construction waste has been carried out.
The Ministry of housing and urban rural development recently issued the guiding opinions on promoting the reduction of construction waste (hereinafter referred to as the opinions), guiding and urging the competent housing and urban rural construction departments at all levels to establish and improve the working mechanism of construction waste reduction and strengthen the source control of construction waste, Promote the transformation of project construction production organization mode, effectively reduce the generation and emission of construction waste during project construction, and constantly promote the sustainable development of project construction and the improvement of urban and rural living environment.
1、 Overall goal by the end of 2020, the working mechanism of construction waste reduction in various regions will be preliminarily established.
By the end of 2025, the working mechanism of construction waste reduction in various regions will be further improved to realize that the emission of construction waste at the new construction site will not be higher than 300 tons / 10000 square meters, and the emission of construction waste at the cast construction site will not be higher than 200 tons / 10000 square meters.
2、 Main measures 1.
To carry out green planning, it is required to implement the main responsibility of the enterprise, and implement the primary responsibility of the construction waste reduction of the construction unit according to the principle of “who produces, who is responsible”; Implement new construction methods, vigorously develop precast buildings, actively promote steel structure precast houses, and promote the construction mode of factory prefabrication, assembly construction and information management; Adopt a new organization mode to promote the reform of project construction organization mode.
At the same time, encourage innovative design, construction technology and equipment, give priority to green building materials, implement full decoration and delivery, and reduce the generation of construction waste on the construction site.
Under the leadership of the construction unit, promote the application of building information model (BIM) and other technologies in engineering design and construction, reduce “errors, omissions and deficiencies” in design, assist construction site management and improve resource utilization.
2.
Implement green design, establish the concept of life cycle, and encourage design units to carry out engineering design by using high-strength, high-performance, high durability and recyclable materials and advanced applicable technical system; Improve design quality.
The design unit shall reasonably determine the site elevation according to the landform, carry out earthwork balance demonstration, and reduce the outward transportation of residue; 3.
Promote green construction, prepare special plans, and clarify the reduction objectives and division of responsibilities of construction waste; Do a good job in design deepening and construction organization optimization.
The construction unit shall refine the node structure and specific methods in combination with the engineering processing, transportation, installation scheme and construction process requirements; Strengthen the construction quality control.
The construction and supervision units shall strictly control the construction quality and strengthen the quality control of each process; Improve the reuse rate of temporary facilities and revolving materials; Promote the combined utilization of temporary facilities and permanent facilities; Implement classified management of construction waste; Guide the reuse of construction waste on the construction site; Reduce the discharge of construction waste on the construction site.
3、 The opinions on safeguard measures require that the overall management should be strengthened, and the competent departments of housing and urban rural construction at the provincial level should incorporate the reduction of construction waste into the local green development and ecological civilization construction system; Actively guide and support, encourage construction waste reduction technology and management innovation, and support the rapid transformation and application of innovative achievements; Improve the standard system and strengthen supervision and guidance.
4、 Original policy guidance of the Ministry of housing and urban rural development on promoting the reduction of construction waste: the Department of housing and urban rural development of all provinces and autonomous regions, the housing and urban rural development (Management) Commission of municipalities directly under the central government, the Beijing Municipal Commission of planning and natural resources, and the housing and Urban Rural Development Bureau of Xinjiang production and Construction Corps: promoting the reduction of construction waste is an important part of the construction waste treatment system, It is an important measure to save resources and protect the environment.
In order to reduce construction waste and promote the transformation and upgrading of green construction and construction industry, the following opinions are put forward: I.
General requirements (I) guiding ideology.
*** Continuously promote the sustainable development of project construction and the improvement of urban and rural living environment.
（2） Basic principles.
1.
Overall planning and source reduction.
Coordinate the stages of project planning, design and construction, prevent and reduce the generation of construction waste in the process of project construction from the source, and effectively reduce the discharge of construction waste in the whole life of the project.
2.
Make systematic promotion according to local conditions.
According to the specific requirements of all localities and the actual situation of the project, integrate resources, formulate plans, take multiple measures at the same time, and systematically promote the reduction of construction waste.
3.
Innovation driven, fine management.
Promote the innovation of construction waste reduction technology and management, promote fine design and construction, and realize the classified control and reuse of construction waste on the construction site.
（3） Work objectives.
By the end of 2020, the working mechanism of construction waste reduction in various regions will be preliminarily established..
