The packaging waste recycling market is expanding

the packaging waste produced by industrial production and people's life is increasing day by day. The annual output of packaging waste in China is about 16million tons, and it is still growing at a rate of more than 10% every year. The environmental problems caused by untimely treatment are mainly manifested in the massive consumption of natural resources, the disposal of waste, the increase of waste management pressure and the environmental impact of waste

investment in packaging waste recycling will not only protect the environment, but also promote the packaging industry, so spring testing machine is also an indispensable development. According to the sustainable development strategy proposed by the state, solid waste should be treated in the direction of reduction, harmlessness and recycling. In addition, the continuous maturity of waste treatment methods provides objective conditions for recycling waste packaging. At the same time, it can develop cheap raw material sources for the packaging industry, reduce the original production costs, solve the worries of the development of the packaging industry, and also open up a new economic growth point for it, which has both economic and ecological benefits

at present, paper, iron, aluminum and glass in Switzerland should be made by everyone, and the reuse rate of glass container packaging should reach more than 86% on average; The recovery rate of German tinplate is 50%, the corrugated paper recovery rate is as high as 95%, and the comprehensive recovery rate of waste newspapers is 78%. In contrast, 4. Lubricating oil analysis the environmental pollution caused by China's packaging products in the process of production, circulation and consumption has not received comprehensive and sufficient attention. Investment in packaging waste recycling is promising

from the technical level, the treatment technology of packaging waste is becoming more and more mature. The treated packaging waste has broad uses and promising market prospects. For example, composting of degradable plastics and soilless culture substrate technology are supporting technologies that require EU countries to immediately restrict the use of disposable plastic bags for environmentally sound treatment of degradable plastic lunch boxes and other products. After recycling, the waste snack box can be mixed with soil or other substrates through crushing and harmless treatment for soilless or semi soil cultivation. The waste plastic oiling technology uses high-performance catalysts to "depolymerize" high-density polyethylene or polypropylene plastics through a certain pressure and temperature, and reconnects the hydrocarbon elements in plastic particles into long-chain hydrocarbons, that is, liquid petroleum, which can produce diesel and gasoline that meet the national standards, with an oil production rate of more than 75%. If necessary devices are installed, liquefied gas and carbon black can also be recovered. By changing the catalyst, toluene, xylene, sodium benzene and other chemical products can be produced

the recycling of packaging materials has obvious economic and ecological benefits. Although there are many kinds of packaging waste, it can be basically divided into four categories according to the material of packaging products: paper products, plastic products, glass products and metal products. Most of the packaging waste is renewable resources. According to the current recycling level, the country recycles cartons every year. 1.4 million tons, which can save 80000 tons of coal, 49 million kwh of electricity, 238000 tons of wood pulp and straw, and 11000 tons of caustic soda; Recycling 1billion glass bottles a year can save 49000 tons of coal needed to produce the same amount of glass bottles. 38.5 million kwh of electricity, 49000 tons of quartz stone and 15700 tons of soda ash; With the collection of 40million iron drums, 48000 tons of steel can be saved; Recycling 100million meters of packaging cloth a year can save 15000 tons of cotton; 30million sacks of various kinds can be recycled, which can save 225000 tons of raw hemp. The total value of the above items amounts to hundreds of millions of yuan

the continuous growth of packaging waste production provides sufficient production resources for recycling. According to the statistics of the total output of the national packaging industry, the current paper packaging products are about 8.35 million tons, plastic packaging products are about 2.44 million tons, glass packaging products are about 4.44 million tons, and metal packaging products are about 1.61 million tons. At the same time, these products are still growing at a rate of 12.5% - 30% every year. Research data show that 1 ton of waste paper can be recycled into 0.8 tons of new paper or 0.83 tons of paperboard; One ton of waste plastic can regenerate 0.75 tons of diesel oil or 0.6 tons of unleaded gasoline. It can be seen that there is no need to worry about the "raw materials" of recycling
