The implementation of the greening scheme of the heyday garbage
At present, the production scale of the recycling of construction waste in China is ranging from tens of thousands of tons to millions of tons, with large scale gap and uneven production level.
Most directly by the mining machinery and the mechanism of sand production process and equipment, equipment adaptability; environmental protection facilities, part of the project of dust emissions; lack of energy consumption index, used in the production of large hydroelectric power consumption; at the same time, the lack of planning and design, part of the project process is not reasonable, resulting in low production efficiency and high production cost. Product quality is not stable, resulting in two times of environmental pollution, and even some projects due to site selection, process and equipment configuration is not reasonable lead production, seriously affected the development of construction waste resource utilization.
Zhengzhou Dingsheng construction waste resource recycling production line provided with other manufacturers is different, Zhengzhou peak in technology top construction waste disposal should be extended to "solutions" and "overall planning", construction waste treatment plan provided by the Zhengzhou peak comply with local building garbage piled up and the distribution characteristics. No one decides the construction waste recycling production line is the same.
For example, Urumqi now produces more than 5 million tons of construction waste every year, mainly including loess, weathered rock and demolition adjunct. The traditional way of treatment is only resource recycling and landfill. In 2014, Urumqi city introduced construction waste recycling technology and projects through PPP model, and invested 270 million yuan to build a renewable building material park. At present, 500 thousand tons of construction waste can be handled every year in the first phase of the project, which effectively relieves the growing problem of construction waste in Urumqi.
Zhengzhou's heyday is strictly following the principle of reduction, innocuous and resourceful in the overall planning and design of construction waste. Construction waste can be reused or reused. It should be recycled. If it cannot be reused or reused, it should be disposed in accordance with relevant laws, regulations and regulations.
