First of all we have to analyze our country renewable scrap metal exports is almost zero, all as a renewable metal recovery, but it also can only meet the demand of one-third of the market in China, the remaining two-thirds of the scrap metal materials currently rely on imports. But with the metal shredding machine, this situation can be completely improved, and we can smash the scrap metal to achieve the reuse of resources. Secondly, we analyzed the demand of the renewable metal industry in China, the product price recovered, the waste trade recovered, and the investment grew rapidly. This year alone discarded items of the development of the market in full swing, this also led to the scrap metal recycling market hot, and the first choice of shredded as scrap metal shredding machine has been vigorously promoted. In the end, China's comprehensive utilization of waste metals is more and more important, and it is identified as a strategic new industry.
