Reuse of waste packaging becomes an investment "gold point"

At present, the annual output of packaging waste in China is around 16 million tons. It is also growing at a rate of more than 10% per 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 matured. 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, reducing the original production costs, with dual economic and ecological benefits. 
With the increase in the amount of packaging waste, the cost of waste disposal has continued to rise, and in the process of rapid development of packaging production, China still has a relatively large number of developed countries in terms of waste management, disposal and recycling. gap. According to statistics, the reuse rate of paper, iron, aluminum and glass containers in Switzerland averaged over 86%; the corrugated paper recycling rate in Germany was as high as 95%, and the overall recycling rate of waste paper was 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 cautioned that the current investment in packaging recycling waste recycling is at the right time. 
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: China 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, 238,000 tons of wood pulp and straw, and 11,000 tons of caustic soda; one year recycled glass. The 1 billion bottles will save 49,000 tons of coal, 38.5 million tons of electricity, 49,000 tons of quartz stones and 15,700 tons of soda ash, and will save 22.5 tons of raw hemp by recycling 3000 sacks of all kinds. The total value of the above items amounts to 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 grow at 12.5% ​​and 30% each year. The research data shows that 1 ton of waste paper can regenerate 0.8 ton of new paper or 0.83 ton of cardboard; 1 ton of waste plastic can regenerate 0.75 ton of diesel or 0.6 ton of no-lead 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 boxes and other environmentally sound disposals, broadening the scope of application of degradable plastics.
