Prospects of Construction Waste Processing

The recycling rate of construction wastes can reach more than 95%. For example, recycled construction wastes are used to make reprocessed bricks, Compared with clay bricks, in order to produce 150 million standard bricks, reprocessed bricks can reduce 240,000 cubic meters of soil, consume more than 40 million tons of construction waste and save land 340 acres of land. In addition, in the process of making bricks, 40,000 tons of fly ash can be consumed, save 15,000 tons of standard coal , reduce 360 tons of SO? emissions.
Resources of recycling of Construction wastes not only have tremendous environmental benefits, but also bring enormous economic benefits. If we have 5 billion tons of construction wastes in 2020 and all of them are changed into recycling materials, they can create value more than 1 trillion.
Biological carbon catches attention of the worldwide. Many scientists assume, carbon element captured by biological carbon is quite stable, which can "lock" the carbon in the underground for hundreds of years, and making the soil more fertile; in addition, it still can reduce the emission of the nitrogen dioxide and methane and   other greenhouse gases.
From the introduction of Biological carbon, Limestone rotary kiln is capable of batch production of biological carbon.
Open coal mining the following advantages: large capacity, short construction period, low mining cost, high labor productivity, low coal investment, high resource recovery rate, and good security conditions. All the world's major coal-producing countries make great efforts to develop open coal mining, whose proportion can reach 60% -80%.
Now, the developed countries are promoting the development of single machine automatization and whole electromechanical integration. The jigger, auto-filter press, sedimentation filtering centrifuge, flotation machine, high-efficiency concentrator and swirl nozzle adopt auto control by computer for parameters.
