Investment in recycled packaging waste is promising

At present, the annual output of packaging waste in China is about 16 million tons, and at the same time it is still growing at a rate of more than 10% each year. The resulting environmental problems are mainly manifested in many aspects such as the consumption of natural resources, the disposal of wastes, the increase of waste management pressure, and the environmental impact of waste.
Relevant experts pointed out that at present, packaging waste has been increasing, and recycling technology has reached an initial maturity. Under the condition that solid waste is treated in the direction of reduction, harmlessness, and recycling, it is not only feasible to invest in the recycling of packaging waste. And it will also promote the development of the packaging industry. On the one hand, this is in line with the country's sustainable development strategy. The strengthening of environmental protection has solved the worries of the development of the packaging industry and opened new economic growth points. On the other hand, advancing to the environmental protection industry can develop inexpensive packaging for the packaging industry. Sources of raw materials, lower original production costs, with dual economic and ecological benefits.
It is understood that the current recycling rate of paper, iron, aluminum and glass containers in Switzerland averages over 86%; the German tinplate recovery rate is 50%, the corrugated paper recovery rate is as high as 95%, and the comprehensive recovery rate of waste newspapers is 78%. In contrast, the environmental pollution caused by the production, circulation, and consumption of packaging products in China has not been fully and adequately valued. Experts warn that there are promising ways to recycle packaging waste.
First of all, the recycling of packaging materials has obvious economic and ecological benefits. According to experts, although there are many types of packaging waste, the packaging materials can be basically divided into four categories: paper products, plastic products, glass products and metal products. Packaging waste is mostly renewable resources. Calculated according to the current recovery level: The country recycles 140,000 tons of cartons a year, which can save 80,000 tons of coal with the same amount of paper, electricity, 49 million degrees, 23.8 tons of wood pulp and straw, and 11,000 tons of caustic soda; 1 billion, can save 49,000 tons of coal, 38.5 million tons of electricity, 49,000 tons of quartz stone, and 15,700 tons of soda ash, and 40 million tons of steel barrels, saving 48,000 tons of steel. Recycling packaging fabrics 100 million meters a year will save 15,000 tons of cotton; recycling 3000 sacks of various kinds will save 22.5 tons of raw hemp, and the total value of the above items will reach several hundred million yuan.
Second, the continuous growth of packaging waste production provides sufficient production resources for recycling. Judging from the statistics of the total output of the national packaging industry, currently there are approximately 8.35 million tons of paper packaging products, 2.44 million tons of plastic packaging products, 4.44 million tons of glass packaging products, and 1.61 million tons of metal packaging products. At the same time, these products also increase at 12.5%-30% each year. Research data shows that 1 ton of waste paper can regenerate 0.8 ton of new paper or 0.83 ton of cardboard; a ton of waste plastic can regenerate 0.75 ton of diesel or 0.6 ton of unleaded gasoline. From this we can see that there is no need to worry about the "raw material" problem of recycling.
Thirdly, the technology for the treatment of packaging waste has become increasingly mature. The treated packaging waste has a wide range of uses and its market prospects are promising. For example, degradable plastics composting and soilless cultivation matrix technology are the supporting technologies for degradable plastic lunch boxes and other products. After discarded snack boxes are recycled, they can be mixed with soil or other substrates by smashing and detoxifying treatment, and used for soilless or semi-aerial cultivation. The waste plastics oiling technology uses high-performance catalysts to depolymerize high-density polyethylene or polypropylene plastics after a certain pressure and temperature, and reconnects hydrocarbons in the plastic particles into long-chain hydrocarbon compounds, that is, liquids. Oil; can produce diesel and gasoline that meet the national standards, with an oil production rate of over 75%. Liquefied gas and carbon black can also be recycled if necessary equipment is installed. By changing the catalyst, it is also possible to produce chemical products such as toluene, xylene and naphthalene.
