Vigorously developing circular economy is an effective way to recycle industrial solid waste. Yili Recycling Industrial Park is a model for the early development of circular economy in Dalate Banner, which has constructed an integrated recycling industry chain of "coal-gangue power generation-ionic membrane caustic soda-PVC-industrial waste residue cement".
The industrial waste residue buried in the supporting ash yard of Yili Chemical was excavated and transported to Inner Mongolia Yili Jidong Cement Co., Ltd. for cement production.
As an important part of the industrial chain of Yili Recycling Industrial Park, Inner Mongolia Yili Jidong Cement Co., Ltd., adhering to the development concept of "city purifier, good government helper", relies on the abundant industrial solid wastes such as carbide slag, fly ash, desulfurized gypsum in the park and the surrounding areas of Dalate Banner to build a new type of cement industry. A new dry process clinker cement production line with 100% carbide slag instead of limestone has been built for the first time in China, which can produce 750,000 tons of cement clinker and 1.1 million tons of high-quality ordinary Portland cement annually, with an annual output value of about 350 million yuan, a cumulative cement production of 16 million tons and a profit and tax payment of about 1.375 billion yuan. At the same time, the supporting cement kiln of the project can co-dispose 30000 tons of hazardous waste and 20000 tons of sludge annually.
"Enterprises comprehensively utilize 1.55 million tons of industrial solid waste from Yili Recycling Industrial Park and surrounding enterprises every year, including more than 1.2 million tons of industrial solid waste from Dalat Banner, and more than 22 million tons of industrial solid waste from Dalat Banner have been absorbed since the establishment of the factory, of which about 17 million tons of industrial solid waste from Dalat Banner have been absorbed." It has realized the local processing, transformation and multiple value-added of industrial solid waste resources. Fan Wenjun, Party branch secretary and general manager of Inner Mongolia Yili Jidong Cement Co., Ltd., said. Inner Mongolia Jianheng Energy Technology Co., Ltd.,
located in Dalat Economic Development Zone, is also committed to the comprehensive utilization of industrial solid waste, and has broken a high-quality development path of "turning waste into treasure" in the field of building materials.
