2 Reuse: Reuse, all packaging or partial packaging after use, after recycling, processing, reuse;
3 Recycle: recycling, packaging waste is easy to recycle and reuse, which is conducive to recycling of resources;
4 Recover: Get new value, packaging waste does not produce toxic gas, does not form secondary pollution, and can generate new resources (such as heat or Other products) in the process of combustion.
