[China paint information] Dongguan produces at least 3million tons of construction waste every year, and these construction waste will turn waste into treasure in the future

at the "two sessions" in 2014, there were up to 7 proposals on the resource utilization of construction waste, which were included in the key proposals of the municipal CPPCC in 2014. Among them, Zheng Jinhuo, Secretary General of the municipal society of civil engineering and architecture, frequently spoke out to promote the resource utilization of construction waste. Relevant proposals were put forward as early as 2008, and were also rated as the excellent proposal of that year. The difference is that there was only one proposal with the keyword "construction waste resource utilization" in that year, and there were six more by 2014

last year, Zheng Jinhuo submitted again the "suggestions on accelerating the recycling of construction waste and the industrialization of special machinery and equipment in Dongguan by taking the opportunity of creating a national ecological city". When this proposal and the other six were listed as the key proposals in 2014, Zheng Jinhuo said, "I am very happy and believe that there will be substantial progress in promoting the resource utilization of construction waste."

neither units nor individuals can dump construction waste at will

Ms. Huang, who lives in Nancheng, said that recently, the construction waste piled up for a long time outside the community has not been transported away. Ms. Huang said that so much construction waste is produced every year, which affects the appearance of the city and causes pollution

it is learned that at present, according to the regulations on the management of urban construction waste, construction waste shall not be mixed with domestic waste, hazardous waste shall not be mixed with construction waste, and dumping sites shall not be established without authorization to receive construction waste. At the same time, no unit or individual is allowed to dump, throw or stack construction waste at will

the Municipal Urban Management Bureau was contacted yesterday. The staff said that the disposal of construction waste must be approved by the urban management department. The Municipal Urban Management Bureau has formulated the guidelines for urban construction waste disposal, including the approval of urban construction waste transportation and the approval of urban construction waste discharge acceptance

enterprises were caught stealing construction waste

however, just a few days ago, Xiegang urban management department also received complaints from citizens, and there was a black spot in Xiegang Industrial Avenue where construction waste was dumped at will. From a distance, it looks like a small black hill. From a close view, it is covered with all kinds of construction waste such as dust, sand and silt, which has caused great damage to the surrounding industrial area environment and green vegetation

on the day of January 10, the law enforcement officers of Xiegang Urban Management Branch found a muck truck dumping construction waste on the open space next to the Industrial Avenue during the inspection. The staff punished it, and according to the relevant regulations, the maximum punishment was not more than 50000 yuan

how is the current construction waste treated? The Municipal Urban Management Bureau said that at present, it is mainly used for direct recycling through self allocation by the market, and a small part is transported to the temporary storage yard in some towns (streets) for treatment

"garbage is not garbage if it is placed in the right place. For example, some road landfills are also used." Zheng Jinhuo said that the use of construction waste in Dongguan is still in its infancy and has not been officially carried out. "Shenzhen is at the forefront, and now Guangzhou and Foshan have also started." Zheng Jinhuo said

proposal focus

Dongguan produces 3million tons of construction waste every year

ZHENG Jinhuo proposed in the proposal that in recent years, our city has declared to the construction department that the construction area of houses has reached 15million ~ 20million square meters every year, including a large number of municipal road engineering projects. In this process, every 10000 square meters of new buildings will generate about 600 tons of construction waste, such as waste bricks and cement blocks. It is estimated that more than 2 million tons of construction waste will be generated in 2013

"in fact, more than 90% of the land available for development and construction in Dongguan has been consumed, and the new development and construction land accounts for less than 10%." Zheng Jinhuo said that the future construction of Dongguan's new city will focus on "demolishing the old and building the new" and "transforming the three old". Every 1 square meter of concrete buildings demolished will produce nearly 1 ton of construction waste

according to the survey of relevant departments in 2012, the annual demolition volume of some demolition companies is about 1.5 million square meters, the production of construction waste is more than 1million tons, and about 3million tons of construction waste will be produced in Dongguan every year, which has brought great pressure to the urban ecological environment, city appearance and health management, and transportation of Dongguan. At the same time, Dongguan is also a city with a lack of construction raw material resources. The resource products such as sand and stone and industrial waste residue required by the building materials production industry are becoming increasingly tense and often in short supply

the resource utilization of construction waste can form two industrial clusters

different from the proposal in 2008, after investigation, Zheng Jinhuo also put forward the problem of industrialization of construction waste resource utilization equipment in Dongguan in the 2014 report. In other words, the construction waste recycling can form two industrial clusters, one is the construction waste recycling construction machinery manufacturing industry cluster according to the data of China Automobile Association, and the other is the construction waste recycling series building materials industry cluster

if we realize the recycling of construction waste and the industrialization of Dongguan, we can not only meet the practical needs of the urbanization process of Dongguan, but also form industrial clusters around the Pearl River Delta and even the whole country to create 100 billion industries

Zheng Jinhuo said that at present, the surrounding city Shenzhen is in the forefront of the country, with at least nine enterprises engaged in the resource utilization and development of construction waste, while Guangzhou, Foshan and other cities have also started in the past two years

he proposed that Dongguan should launch the pilot work of construction waste resource industrialization as soon as possible. This work can be led by the Dongguan building energy conservation department to organize social capital to explore and try, and quickly carry out the pilot work of construction waste treatment and recycled concrete, mortar and environmental brick recycling base

secondly, formulate and improve the management measures for the recycling of construction waste as soon as possible. Put an end to the random discharge of construction waste from the source and reduce the damage to the natural environment and urban environment. In addition, he proposed the need to set up corresponding special funds and reward systems to increase publicity

reply to the proposal

the committee member responded that

establish a residual sludge management system, and Dongguan took the pilot residual sludge recycling

Municipal Urban Management Bureau as the sponsor, and responded to the case that China's manufacturing enterprises' R & D investment is generally low. The reply proposed to establish a perfect and effective management system for residual sludge

the Municipal Urban Management Bureau responded that it would communicate and coordinate with relevant units and departments, and urged relevant departments to continue to deepen the formulation of supporting policies for the recycling industry of residual sludge, guide and support the recycling of residual sludge from the policy level, and gradually promote the recycling of residual sludge

this year, the urban management department will also carry out a detailed investigation on the current situation of residual sludge and soil in our city, comprehensively grasp the production volume, nature, classification, acceptance and resource utilization capacity of residual sludge and soil in our city, and prepare a special plan for the comprehensive treatment of residual sludge and soil

according to the actual situation of the town (street), reasonably set up the waste mud and soil storage yard to realize the full storage of the waste mud and soil in the area. Gradually build facilities for the resource utilization of residual mud and soil, cultivate enterprises suitable for the resource comprehensive utilization of residual mud and soil in our city by learning advanced experience and technology, and strive to set up technologically advanced resource comprehensive utilization equipment in the planned consumption yard to carry out the resource treatment of residual mud and soil locally

the Municipal Urban Management Bureau responded that if the conditions are appropriate, individual towns and streets should be used as pilot projects to gradually promote the management of residual mud and muck in our city. Zheng Jinhuo said that according to the response of the urban management department, our city will soon carry out the pilot work of the storage of residual mud and muck

very satisfied with the reply and hope to act faster

Zheng jinhou said he was very satisfied with the reply. In the past year, the relevant functional departments had a serious and responsible attitude through visiting surrounding cities and investigating the current situation in Dongguan

"a proposal can improve the utilization of construction waste in our city, turn waste into treasure, and more importantly, better protect the ecological environment, which is conducive to promoting energy conservation and emission reduction in Dongguan." Zheng Jinhuo said that Dongguan has begun to take action and hopes that this action will be faster
