The development of the manufacturing industry can promote energy conservation. Practice at home and abroad shows that, thanks to extensive use of waste materials, remanufactured products can save more than 60% of energy and more than 70% of materials, and carbon dioxide and other waste emissions are substantially reduced. China is the roost manufacturing country in the world, but the per capita resource is relatively less than normal. At present, the consumption of China's oil import dependency has been as high as 57%, and iron ore and a variety of non-ferrous metals also rely heavily on imports. To develop recycling economy by remanufacturing can effectively overcome the resource and environmental constraints, and make the manufacturing industry the resource-conserving, environment-friendly green low-carbon industries.
The development of the manufacturing industry can reduce production costs, and speeding up the renewal of equipment is a key link to improve production efficiency. The aim of why industrial value-added tax shift from production to consumption-based is to promote technological innovation focused on equipment renewal. The equipment is an important part of the cost of production. Due to the significant reduction of the consumption of energy and raw materials, manufacturing costs is only one-third of the new product or even a quarter of it.
The development of the remanufacturing industry can to meet user needs. Repair high-tech life assessment of old products based on engineering design analysis and remanufacturing used products, which can make the quality of the manufactured products like sand washing machine and dust collector with high quality.
