Industry information | domestic waste is classified, what about construction waste?


In China, a huge amount of solid waste is produced every year

.

The second is to form a long-term management mechanism with clear objectives and responsibilities, powerful management and control, orderly disposal, strict investigation and effective supervision

.

Countermeasures 4: accelerate the process of building industrialization, promote recyclable prefabricated buildings, increase the proportion of full decoration of new residential buildings, and try to sell commercial houses in a unified hardbound way; promote green construction, establish the existing building demolition evaluation permit system, establish a scientific and standardized construction waste emission reduction index system, and reduce the amount of waste from the source; pay the transportation and disposal costs of construction waste In order to ensure the legitimate interests of transportation enterprises and recycling enterprises, curb dumping and unloading, encourage “zero emission” of construction waste and implement the charging system of emission disposal

.

According to the national annual report on prevention and control of solid waste pollution in large and medium-sized cities in 2020 issued by the Ministry of ecology and environment, the total annual output of general industrial solid waste, industrial hazardous waste, medical waste and domestic waste in large and medium-sized cities is 1.38 billion tons, 44.989 million tons, 843000 tons and 235.602 million tons respectively Tons

.

Ye Qiang said that the current disposal methods of construction waste in Shanghai are mainly to set up construction waste allocation sites, centralized collection and transportation points and temporary stacking points in various regions in a planned way

.

10 domestic waste treatment plants, 100% harmless treatment; kitchen waste treatment project started; from May 1 this year, garbage classification will be officially implemented, covering 76 demonstration streets and 588 demonstration communities At present, Jinan, Shandong Province is building a waste free city, exploring the source reduction, resource utilization and harmless treatment of solid waste, promoting the transformation of urban green development and improving the quality of urban ecological environment

.

The exploration of Jinan is also the key work of many cities during the “14th five year plan” period

.

Countermeasures 3: popularize the concept of reducing construction waste first, recycling and harmless treatment, actively promote new technologies and new products of construction waste recycling, guide the public to apply construction waste recycling products, and create a good atmosphere of public understanding, support and joint participation

.

With domestic waste classification as the entry point and waste free urban construction as the guide, the whole industry has made every effort to promote the comprehensive management reform of solid waste, and gradually established a fine management system from source reduction, terminal collection and transportation to terminal treatment

.

Strengthen the real-time monitoring of transport vehicles, and comprehensively improve the management efficiency

.

The phenomenon of “garbage besieged city” in some cities is still serious

.

According to the figures provided by the Ministry of housing and urban rural development, during the 13th Five Year Plan period, the quantity and capacity of urban domestic waste treatment in China increased rapidly, the rate of harmless treatment increased significantly, and the proportion of waste incineration exceeded 50%

.

However, there are still phenomena of disorderly stacking, disorderly discharging and disorderly unloading

.

How to strengthen the utilization of construction waste resources, ye Qiang put forward the Countermeasures — countermeasure 1: according to China’s existing laws and regulations, standard system and application procedures, the planning of construction waste utilization should be prepared, the phased objectives of utilization should be clarified, the implementation plan should be formulated, the reduction measures should be determined, and the construction project should include the generation, classification, transportation, recycling and utilization of construction waste Application and other aspects of the regulatory system

.

Welcome to pay attention to “environmental protection vision”! #Nationwide, construction waste resource utilization lags behind, and the reuse rate is less than 1%

.

“With the superposition of multiple policies, opportunities and challenges coexist.

.

The solid waste management system has matured

.

Promote the early completion, early operation and early effect of the municipal construction waste resource recycling center; list the recycled products that meet the standards in the recommended catalogue of green building materials and the government green procurement catalogue, specify the priority of construction waste recycling products in government investment projects, and specify the proportion of construction waste recycling products in other projects

.

The municipal and provincial capital cities basically established the recycling system, and the domestic waste recovery rate further increased

.

Solid waste is an important source of environmental pollution

.

The scale of waste incineration power generation increased from 235000 T / D at the beginning of 2015 to about 570000 T / D at the end of 2020, with a year-on-year growth of 2.4 times and a compound annual growth rate of nearly 20%

.

By 2020, 53 of the 95 state-owned enterprises in China are involved in the eco-environmental industry, covering almost all the segments of the environmental protection industry

.

The proposal of the CPC Central Committee on formulating the fourteenth five year plan for national economic and social development and the long-term goals for the year 2035 put forward the principles that must be followed in the economic and social development during the fourteenth Five Year Plan period, including “continuous reduction of total emissions of major pollutants”

.

In order to change the society from a “consumption body” that devours resources into a “circulation body”, China has deepened the reform of comprehensive solid waste management by focusing on the pilot work of waste free city construction

.

Due to the low profit rate of construction waste recycling enterprises, in order to promote their sustainable and healthy development, it is necessary to increase policy support ■ in terms of finance, price subsidies should be given to the recycling products with advanced technology and excellent quality; in terms of tax, preferential policies of value-added tax and income tax reduction should be implemented for construction waste recycling enterprises in comparison with high-tech enterprises; in terms of loans, the government should pay more attention to the construction waste recycling enterprises, Preferential or discount interest rates will be implemented to support the development of enterprises and project construction

.

There are still some problems, such as large historical storage, unclear industrial scale and low comprehensive utilization rate

.

There are phenomena of running, scattering and leaking in the process of transportation, which bring great pressure to the ecological environment protection

.

Industry experts said that construction waste treatment will be the focus of waste free city construction

.

First, centralized stacking is implemented, and then basic engineering, low-lying land backfilling and centralized landfill are carried out

.

Zhou Kang, Secretary of the Party committee and executive director of China Environmental Protection Group Co., Ltd., said that during the 13th Five Year Plan period, China’s solid waste management market developed rapidly, investment continued to be high, and cross-border giants joined in, resulting in increasingly fierce competition

How to strengthen the resource utilization of construction waste? What is the situation of solid waste management in China? How to carry out the prevention and control of environmental pollution by solid waste during the “14th five year plan” period, so as to continuously improve the quality of ecological environment? The latest hazardous waste treatment methods are summarized! The law enforcement of prevention and control of environmental pollution by solid waste is coming to your workshop for inspection! With the basic requirements of solid waste and hazardous waste storage technology analysis | organic hazardous waste packaging container recycling technology application picture read | the work report of the Minister of the Ministry of ecological environment at the national ecological environment protection work conference in 2021, ye Qiang submitted a proposal, calling for a radical cure of this city’s “stubborn disease”, accelerating the utilization of construction waste resources, protecting the ecological environment, and promoting the construction industry Transformation and upgrading

.

Only in this way can we accelerate the utilization of construction waste resources, protect the ecological environment, and promote the transformation and upgrading of the construction industry

.

There are more than 20 kinds of harmful substances in construction waste

.

According to statistics, during the 13th Five Year Plan period, the total investment in domestic waste harmless treatment facilities in China exceeded 250 billion yuan, becoming an important engine for stimulating domestic demand

.

What is the situation of solid waste management in China? How to carry out the prevention and control of environmental pollution by solid waste during the “14th five year plan” period, so as to continuously improve the quality of ecological environment? 1

.

In order to build a waste free city, we should start from the construction waste, which is the overall portrayal of China’s solid waste

.

We should regularly organize and carry out joint law enforcement, timely investigate and deal with the illegal disposal of construction waste, and constantly improve the law enforcement and management level of construction waste in the city

.

“Solid waste management is an important part of China’s ecological civilization construction, and an important measure to improve environmental quality, prevent and control environmental risks, maintain ecological security, and protect people’s health.” Tong Lin, director of the environmental health engineering technology research center of the Ministry of housing and urban rural development, said that as of the end of the 13th five year plan, China’s solid waste management has undergone a historic turn from recognition to practice, the solid waste management system has matured, and the solid waste management industry has entered a fast lane
