Proper governance of construction waste our beautiful clean homes
City have been expanding row upon row of high-rise buildings; infrastructure continues to accelerate, and improved quality of life. We enjoy a better life, construction waste was outside the room quietly erode our environment in a warm room; we embrace modern architecture and infrastructure to bring us all, but can not ignore such a long-term disturbing problem increдробилка для камней своими рукамиasingly serious phenomenon: the growing number of construction waste piled up at random, and the governance issues are imminent.Construction waste definition muck that is generated during the construction process, spoil, disposable materials, Yuni and other waste. It is understood that the construction of the 10,000 m2 building will produce 500-600 tons of construction waste; while every demolish old buildings of 10,000 square meters, will produce 7000-13000 tons of construction waste. At present, the number of China's construction waste accounted for 30% -40% of the total amount of municipal solid waste. Faced with such a grim situation, how to handle and use of construction waste issues of common concern.The environmental community is popular so the old saying goes: "the world on this garbage, only misplaced resources." Japanese construction waste as a "building-products", attaches great importance to its re-development and utilization as a renewable resource; U.S. Government developed the Superfund Act, the provisions of any industrial waste production enterprises must properly handle and are not allowed to arbitrarily dump, which limit the amount of construction waste generated source consciously seeking to promote enterprise construction waste resource utilization; the French CSTB company is Europe's leading waste and construction industry, "Group specifically to co-ordinate the waste and construction business in Europe; Netherlands, more than 70% of construction waste can be recycled But the Dutch government hopes to increase this percentage to 90%, so they developed a series of laws, establishing limit the dumping of waste pкварцевый песок состоит изrocessing, mandatory recycling run quality control system ...At present, the domestic processing of construction waste and there is no good way. Construction waste, in addition to a small number of scrap metal, plastic and other materials are recovered, the vast majority of untreated directly transported to the countryside or rural, stored in the open air or simply landfill approach, and this approach will the soil causing serious harm, also pose a threat to the environment. Development of the times, this approach can not meet the requirements of society.In recent years, China has many experts called for: to improve the utilization of resource recycling, to alleviate the shortage of resources, pressure to reduce environmental pollution. Construction waste material after the use of related equipment processing, is a way to once again take advantage of the new resources. The main ways: waste concrete → sorting → crushing → screening → recycled aggregate (according to the old concrete strength, control the different particle size of broken) → preparation of recycled concrete mixture ratio (strict control).Xuan Shanghai World Engineering Technology Co., организация ювелирного производсLtd. developed the production in order to meet the needs of society, set by a combination of jaw crusher, impact crusher, impact sand making machine, vibrating screen, dust collector equipment mobile crusher station . All of the crushing plant equipment as well as architecture and are based on the most advanced steel research and development from customers can do one hundred percent assured quality. The performance of its main advantages is the use to select the best production base according to the source of raw materials; usage was based on the stone, in a number of site turnover use or gathered several equipment concentrated feed, reduce idle time of equipment in the shortest time; installation convenient, repair and maintenance; All process using the dust and noise reduction equipment, automated operation, and high efficiency. Construction waste crushing, screening procedures, into useful construction materials recycling, is mainly used for road construction, masonry, brick-making, turning waste into treasure. Meanwhile, the mobile crushing station a good solution to the traditional crusher in production when the environment pollution to meet national standards, can shaping crushing of construction waste.
