At present, the concept of green materials, including the advanced nature of the material itself (excellent quality, low energy consumption and production materials), the security of the production process (low noise, pollution), the material used reasonable(save, recyclable), and modern engineering requirements, specifically green material has the Performance, and in the preparation, processing, use and even end-of-life recycling processing lifecycle process with less energy consumption high utilization of resources, environmental pollution, and the easy recovery of material processed.
Green procurement, including two aspects: one is the green procurement of raw materials enterprises in the procurement of raw materials through source control, consider whether the material is recycling, re-use of environmentally friendly materials, avoid material and fuel use and recovery after treatment of environmental pollution and Energy waste [2].
