Recycling packaging waste in China promotes the development of packaging industry
The rapid development of China's packaging industry has led to many environmental problems, especially the environmental pollution caused by the plastic packaging industry.
at present, the packaging waste is increasing day by day, the recycling technology has initially matured, and the state proposes that solid waste should be treated in the direction of reduction, harmlessness and recycling, investing in the recycling of packaging waste is not only feasible, but also promotes the development of the 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, entering the environmental protection industry can develop cheap raw material sources for the packaging industry, reduce the original production cost, and have both economic and ecological benefits.
with the increasing amount of packaging waste, the cost of waste disposal continues to rise. It is the general trend to increase the recycling of packaging waste. However, in the process of rapid development of packaging production, there is still a big gap between China and developed countries in the management, disposal and recycling of waste.
First of all, the recycling of packaging materials has obvious economic and ecological benefits. According to relevant experts, although there are many kinds of packaging wastes, they can be basically divided into four categories: paper products, plastic products, glass products and metal products according to the materials of packaging products, packaging waste is mostly renewable resources.
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, the plastic packaging products are about 2. 44 million tons, and the glass packaging products are about 4. 44 million tons, metal packaging products are about 1. 61 million tons. At the same time, these products are also 12. 5%-The growth rate varies from 30%. Research data show that 1 ton of waste paper can regenerate 0. 8 tons of new paper or 0. 83 tons of cardboard; 1 ton of waste plastic renewable 0. 75 tons of diesel or 0. 6 tons of unleaded gasoline. This shows that the recycling of'Raw materials'There is no need to worry about the problem.
Thirdly, the treatment technology of packaging waste is becoming more and more mature. The treated packaging waste has broad uses and promising market prospects. After recycling, waste fast food boxes can be mixed with soil or other substrates through fragmentation and harmless treatment for soilless or semi-soil cultivation. Waste plastics oiling technology uses high-performance catalysts to combine high-density polyethylene or polypropylene plastics'Depolymerization' It can produce diesel and gasoline that meet the national standards, and the oil production rate is over 75%. If necessary devices are installed, liquefied gas and carbon black can also be recovered. By changing the catalyst, chemical products such as toluene, xylene and pure benzene can be produced.
In addition, with waste plastics (Including PE, PP, PVC, PS)And filling mixture ( Including a variety of urban and rural wastes such as activated carbon waste residue, crushed animal and plant waste, weathered coal, humic acid and other powders) The cost of coating is only about 300 yuan/ton higher than that of ordinary compound fertilizer. This is a change. 'White pollution'For'Green fertilizer' The environmental protection project can absorb a large amount of packaging waste.
entering the environmental protection industry in an all-round way can win the second great development opportunity for the packaging industry. Enterprises can get double ideal returns if they start early.
