Packaging recycling is a very important part of the packaging cycle system. On the one hand, packaging waste can effectively save natural resources and energy through recycling. On the other hand, packaging recycling can greatly reduce the impact and damage of packaging waste on the environment. In the packaging recycling system, the most important thing is how to deal with, recycle and reuse packaging waste.
Importance of packaging recycling
With the development of economy and the improvement of people 's living standards, China consumes a large amount of wood, steel, plastic and other materials for product packaging every year. According to the survey, packaging waste accounts for about half of domestic waste. China has a large amount of materials used for product packaging every year. The consumption of paper and cardboard reaches 2.4 million tons, wood reaches more than 5 million cubic meters, steel for iron barrels reaches 360,000 tons, cloth for packaging is more than 200 million meters, sacks are more than 400 million, wine bottles are more than 2 billion, cement bags are 1.2 billion ( equivalent to more than 300,000 tons of kraft paper ). In addition, it also consumes a lot of tinplate, aluminum, plastic and other packaging materials.
In the face of these serious problems, packaging recycling is imperative. Because packaging recycling can not only save raw materials and energy, but also reduce packaging waste and avoid environmental pollution. A large number of waste packaging not only causes a waste of resources, but also has a serious impact on the social environment and the natural environment. Packaging recycling can not only save raw materials and energy, create economic benefits, but also reduce packaging waste and prevent environmental pollution.
Relevant statistics show that 140,000 tons of cardboard boxes are recovered in one year nationwide, which can save 80,000 tons of coal, 49 million kilowatt hours of electricity, 238,000 tons of wood pulp and straw, and 11,000 tons of caustic soda for the country to produce the same amount of cardboard. One year 's recycled wood packaging is equivalent to 180,000 cubic meters of wood, and a simple warehouse of 2.5 million square meters can be built, which is equivalent to about 70,000 mu of forest being cut down every year. One year recovery of 1 billion glass bottles ( about 35,000 tons ), you can save the production of the same number of glass bottles required 49,000 tons of coal, electricity 38.5 million kilowatt-hours, 49,000 tons of quartz stone, soda ash 157,000 tons. In addition, 4 million iron drums are recovered in one year, which can save 48,000 tons of steel. 1 year recycling packaging cloth 100 million meters, can save cotton 15 million kilograms ; in one year, 30 million kinds of sacks are recovered, which can save 22,500 kg of raw hemp.
In addition, experts estimate that more than 400 cities in China are surrounded by garbage. In these ' industrial waste ' and ' domestic waste ', packaging waste accounts for more than 40 %. If the packaging recovery rate reaches 50 %, it can reduce urban waste by 20 %, which will make a significant contribution to environmental protection.
