Permeable brick prices : With the acceleration of urban modernization and village urbanization, the output value of construction waste is increasing. Most of these construction wastes were transported outside the city or villages without treatment, and were piled up or landfilled in the open air, or even dumped directly into rivers, lakes, and ponds. This consumes a lot of land acquisition fees,
With the acceleration of urban modernization and village urbanization, the output value of construction waste is increasing. Most of these construction wastes were transported outside the city or villages without treatment, and were piled up or landfilled in the open air, or even dumped directly into rivers, lakes, and ponds. This consumes a lot of construction expenses such as land acquisition costs, waste removal costs, etc. There are also many social problems such as ecological damage, land occupation, water pollution, and city appearance, especially the dust and dust during the removal and accumulation process. Problems such as Sha Feiyang have caused serious environmental pollution. Therefore, how to dispose of construction waste scientifically has become a serious subject that the government's social and public affairs management is eager to crack.
透水砖 ，当它“变废为宝”时，能够给社会带来明显的经济和环境效益。 In fact, these construction wastes are not wastes in the real sense. It is a useful resource that can completely become a recycled permeable brick . When it “turns waste into treasure”, it can bring significant economic and social benefits to society. Environmental benefits. Some experts estimate that by 2020, at least 500 million tons of construction waste will newly emerge in China, and 50% of it will be converted into recycled green building materials such as standard bricks and blocks, which will be worth 600 billion yuan. From this point of view, the scientific treatment of construction waste and its "turning waste into treasure" is an extremely serious subject. It is of great significance to save resources, protect the environment and sustainable development of the construction industry.
Because of this, many cities in China have issued relevant guidelines and regulations for the resourceful and harmless treatment of construction waste, and some cities have also presented professional companies that specialize in the recovery and treatment of construction waste. However, from the current point of view, there are still many urgent problems to be solved in the recovery and treatment of construction waste. There are two key points in the process: First, the public's awareness of environmental protection and the classification and storage of construction waste are not strong, resulting in glass, wood products, muck, residual mud, concrete Wastes such as cement, cement casting, etc. are piled up, thus increasing the difficulty of recovering manpower, material resources, financial resources and reuse; secondly, the lack of government investment and the lack of new technologies, new processes and new equipment for recovery processing make the recovery rate lower. . Therefore, in order to make the construction waste “turning waste into treasure”, the national coercive force should be exerted to implement the regulations for the regulation, reduction and resource utilization of construction waste disposal.
First of all, governments at all levels must strengthen the promotion of laws and regulations such as the "Law of the People's Republic of China on Cleaner Production Promotion", the "Law of the People's Republic of China on the Prevention and Control of Solid Waste Pollution Environment" and the "Law of the People's Republic of China on the Promotion of Recycling Economy", and continue to promulgate it in accordance with local conditions. Improve relevant rules and regulations, and adhere to strict laws, so that there is law to follow, laws must be followed, and all illegal acts such as illegal dumping of construction waste, rough transportation, and environmental damage are eliminated. Together, we must establish a sound and consistent management system and useful operating mechanisms, avoid "single fights" of functional departments, and establish a scientific operating mechanism of "government promotion, enterprise-oriented, and social participation."
Secondly, the government's functional departments should strengthen the guidance for construction removal, construction and construction, implement on-site supervision, and do a good job of inspection of each process. For the constructions to be removed, the construction personnel shall be instructed to sort and deposit them according to the nature of the construction materials, in order to reduce unnecessary costs when recovering and using; for the new construction, the construction unit shall be advised to make a budget for the construction materials and reduce the construction materials due to excess. Probability of conversion to construction waste. Together, we should strengthen the education of construction personnel, so that construction personnel realize the harmfulness of waste construction materials to individuals and the whole society. Units or personnel responsible for quality supervision shall supervise construction units to cut corners, cut materials, and refill in order to reduce the occurrence of unnecessary construction waste caused by repairs, reinforcements, and even reconstruction.
In short, making construction waste “turning waste into treasure” into recycled environmental protection bricks is a social work and a systematic project. It requires the government to introduce supportive policies to accelerate the pace of urban construction waste recovery and utilization, and promote the continuous development of urban ecological environment. Improve.
