The concept and characteristics of glass packaging reverse logistics Glass packaging reverse logistics mainly refers to the process of moving from the downstream nodes of the glass packaging supply chain to the starting point from customers, retailers, etc. to implement closed recycling of glass packaging resources and then reuse them or make them get correct disposal to reduce environmental pollution. There are four main treatment methods for glass reverse logistics: packaging reuse, re-furnace reengineering, raw material reuse and transformation and utilization. Non-damaged or trimtable glass bottles through simple cleaning, process treatment direct reuse, damaged glass bottles are quite semi-finished raw materials for furnace manufacturing, for easy to classify glass bottles for raw material reuse, used as a variety of glass products manufacturing raw materials, and for some other glass it is necessary to develop the application of glass waste in other fields other than bottle making, that is, transformation and utilization, such as frosted flooring.

Different product reverse logistics have different characteristics, glass packaging reverse logistics has the following characteristics: glass reverse logistics collection and transportation difficulties. Glass weight, brittle and fragile, easy to cut people, recycling difficulties, not only like glass bottles, long-distance transportation, if not packaged, glass bottles are fragile, increasing logistics costs and reverse logistics pressure.

Glass sorting is difficult. These include two aspects: the selection of colors and the fine selection of impurities. General daily glass is divided into three colors, transparent color, brown and green, containing a variety of trace additives, to recycle must be three colors of waste glass sorted, can not be mixed, if not for color selection direct use, then the use of single use. For recycled glass bottles, debris such as metals and ceramics must be removed, otherwise the defects of the product will not even be produced.

The reuse value of glass returned by reverse logistics is low. China's technology is relatively backward, for the recycled waste glass, it is only a change in physical form, and the transformation and utilization of glass is very shallow.
