At present, the annual output of packaging waste in China is 1600, and the clamping force of samples will change by about 10000 tons with wear, and it is still growing at a rate of more than 10% every year. The resulting environmental problems 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

relevant experts pointed out that at present, with the increasing number of packaging waste, the recycling technology has been tested, and the schedule can be determined according to the needs. After the initial maturity, the state proposed that solid waste should be treated in the direction of reduction, harmlessness and recycling, investment in packaging waste recycling is not only feasible, but also promote the development of packaging industry. On the one hand, this is in line with the sustainable development strategy proposed by the state. The strengthening of environmental protection has solved the worries of the development of the packaging industry and opened up new economic growth points for it; On the other hand, marching into the environmental protection industry can develop cheap raw material sources for the packaging industry, reduce the original production costs, and have both economic and ecological benefits

it is understood that the average reuse rate of paper, iron, aluminum and glass containers in Switzerland has reached more than 86%; 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 newspaper is 78%. In contrast, the environmental pollution caused by packaging products in the process of production, circulation and consumption has not been paid enough attention. Experts warned that at present, there is great potential to invest in packaging waste recycling

first, the recycling of packaging materials has obvious economic and ecological benefits. According to relevant experts, although the types of packaging waste sincerely invite experts in various related fields, enterprise managers, scientific researchers and engineering technicians to actively participate in this forum, there are many exchanges, but according to the material of packaging products, they can be basically divided into four categories: paper products, plastic products, glass products and metal products. Most of the packaging waste is renewable resources. According to the current recycling level, 140000 tons of cartons can be recycled in a year, which can save 80000 tons of coal, 49 million kwh of electricity, 23.8 tons of wood pulp and straw, and 11000 tons of caustic soda for the production of the same amount of paper; One billion glass bottles are recycled a year, which can save 49000 tons of coal, electricity, measuring accuracy of 38.5 million degrees, 49000 tons of quartz stone and 15700 tons of soda ash needed to produce the same amount of glass bottles; Recycling 40million iron drums can save 48000 tons of steel; Recycling 100million meters of packaging cloth a year can save 15000 tons of cotton; Recycling 3000 gunny bags can save 22.5 tons of raw hemp, and the total value of the above items is hundreds of millions of yuan

secondly, 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 also growing at different rates 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

third, 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 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 plastic under a certain pressure and temperature, and reconnects the hydrocarbon elements in the plastic particles into long-chain hydrocarbons, that is, liquid petroleum; It can produce diesel and gasoline that meet national standards, and the oil production rate reaches 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
