The concept of green supply chain was first proposed by the Manufacturing Research Association of Michigan State University in 1996 in an "Environmentally Responsible Manufacturing (ERM)" study, also known as Environmentally Conscious Supply Chain (ECSC). Or Environmental Supply Chain (ESC) is a modern management model that comprehensively considers environmental impact and resource efficiency in the entire supply chain. It is based on green manufacturing theory and supply chain management technology, involving suppliers, production plants , sellers and users, the purpose is to make the product from material acquisition, processing, packaging, warehousing, transportation, use to the entire process of disposal, the impact on the environment (negative effect) is the smallest, and the resource efficiency is the highest.

For enterprises, green supply chain management should not be a mandatory environmental protection strategy, and can be consistent with the economic interests of the enterprise. It is not only a behavior with significant social benefits, but also an effective means to achieve significant economic benefits. The current enterprises pay attention not only to their competitiveness but also to their own social image. More and more important customers have proposed to have a set of effective environmental management measures as suppliers. Green supply chain can avoid waste of resources, enhance the social responsibility of enterprises, bring good reputation and brand image of green products to enterprises, and expand the product market. The savings in production raw materials reduces the life cycle cost of the final product, so that the end consumer can get a safer and more environmentally friendly product at a lower price. The green supply chain will comprehensively improve or beautify the working environment of the employees of the enterprise, which can not only improve the health of the employees and improve the safety of work, increase the enthusiasm of the employees to create greater profits, further create a better social image for the enterprise, and create a better social image for the enterprise. Add intangible assets.

The foundry industry under the management of green supply chain can reduce the waste of resources and save energy in the production process by strengthening the internal management of the enterprise, rethinking, designing and changing the mechanism of operation and assessment formed by functional departments in the old environment. and reduce environmental pollution; implement green procurement, purchase energy-saving and environmentally friendly raw materials and parts, reduce the inventory of raw materials and parts, and make full use of excess equipment and materials of enterprises; improve production capacity using renewable resources, remanufacture or remanufacture The ability of the used components to be combined into the overall system, the ability to disassemble the accessories, and how these production processes can effectively reduce the waste of materials, etc.; according to the characteristics of the organization and products, select the treatment methods that are favorable for product recycling, in order to achieve Maximize the use of recycled resources and corporate advantages to achieve green supply chain in a true sense.
