In recent years, our factory focus on technological innovation, and strive to improve the comprehensive utilization of resources, turning waste into treasure, continue to promote the recycling economy, the virtuous cycle of environmental and energy construction to achieve a "resources - products - renewable resources - recycled products". I plant for the development of circular economy practice has aroused widespread concern, the media recently, "Ningguo today" and "Xuancheng daily" published articles have been reported respectively.

The article points out: Ning resistant General Factory is specializing in the production of wear-resistant castings factory. In the traditional casting production belongs to the labor-intensive industry. How to reduce energy consumption, reduce environmental pollution, and can continue to expand production capacity, improve the overall economic efficiency of enterprises? In recent years, the factory rely on scientific and technological innovation, strengthen the internal management of enterprises to carry out clean production, the implementation of environmental management system, gradually embarked on the development of circular economy, promote new ways of sustainable development of enterprises.

The article said, in recent years, Ning factory staff to fully mobilize the high creativity, carry out technological innovation, make every attempt of energy saving. Old sand recycling is to reduce the cost of castings, improve casting quality, reduce environmental pollution and save resources is an important measure. The factory production of wear-resistant castings with metal mould sand technology and machine casting production line, all using the resin coated sand, annual consumption of 40000 tons. In general, the sand can only be used once as a waste, not only consume valuable resources, and the impact of the environment, also make the casting production cost increase. Based on the analysis of domestic and foreign coated sand thermal reclamation technology and equipment, the factory carry on the innovation of the key equipment of heat - boiling roasting furnace. By means of the coated sand thermal reclamation technology and equipment research, transformation and test, successfully put the low-pressure hot gas furnace gas as the heat source of boiling roasting furnace, to replace diesel for coated sand regeneration, energy saving effect is very significant. At present, the use of coated sand factory all made, all the old sand regeneration after repeated use, only this one, can create an annual economic benefit of about 20000000 yuan. The factory also make full use of combustion heat to save nearly 20000 tons of standard coal, the circulating water system of investment 5800000 yuan to build, water saving 260000 tons per year. For a long time, the factory after the production of steel slag dumps and landfills. 2005, smart people will repeatedly Ning resistant slag separation by whipped up, may choose Tieda 100 tons of slag, which is 4 times the original artificial selection of iron, the annual increase effectiveness of 2000000 yuan.

The article said, in recent years, Ning resistant plant in circular economy and environmental protection investment in total investment of 100 million yuan, invented 32 patents, introduction, update, additions of more than 20 advanced production lines, the company has passed the ISO9001:2000 quality management system certification and ISO14001 environmental management system. The best-selling products, exported to the United States, Japan and other 30 countries and regions.
