The trend of environmental protection packaging and recycling

the rapid development of China's packaging industry has caused many environmental problems. The comprehensive march into the environmental protection industry can win the second great development opportunity for the packaging industry. Enterprises can start as soon as possible and are expected to obtain double ideal returns

at present, the packaging waste is increasing day by day, and the recycling technology has been preliminarily mature. Under the condition that the state proposes to treat the solid waste in the direction of reduction, harmlessness and recycling, it is not only feasible to invest in the recycling of packaging waste, 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 not only solves the worries of the development of the packaging industry, but also opens up a new economic growth point 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 cost, and have both economic and ecological benefits

with the increase of the amount of packaging waste, the cost of waste treatment continues to increase, and self-lubricating materials will have more uses. It is a general trend to strengthen the recycling of packaging waste. However, in the process of the 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 (4) the main use is first. 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 according to the material of packaging products: paper products, plastic products, glass products and metal products. Most of the packaging wastes are renewable resources

secondly, the continuous growth of packaging waste output 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 products after plastic packaging and supporting steel strand clamps are about 2.44 million tons, the glass packaging products are about 4.44 million tons, and the metal packaging products are about 1.61 million tons. At the same time, these products are growing at a rate ranging from 12.5% to 30% every year. Research data show that 1 ton of waste paper can be regenerated into 0.8 tons of new paper or 0.83 tons of paperboard; 1 ton of waste plastic is renewable 0 To produce 75 tons of diesel oil or 0.6 tons of unleaded gasoline with more functions and more beautiful packaging. 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. 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, 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, pure benzene and other chemical products can be produced

in addition, waste plastics (including PE, PP, PVC, PS) and filling mixtures (including a variety of urban and rural wastes such as activated carbon residues, crushed animal and plant wastes, weathered coal, humic acid and other powders) are used to form a fertilizer coating. The coating cost is only about 300 yuan/ton higher than that of ordinary compound fertilizers. This is an environmental protection project to change "white pollution" into "green fertilizer", which can absorb a large amount of packaging waste
