China's packaging industry fully develops towards environmental protection trends

The rapid development of China's packaging industry has caused many environmental problems. A full-scale entry into the environmental protection industry will provide opportunities for the packaging industry to win a second major development. Enterprises can expect to achieve a double ideal return as soon as possible.

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 resource recycling, investment in the recycling of packaging waste is not only feasible, but 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 up new economic growth points for it.

On the other hand, to enter the environmental protection industry can develop cheap sources of raw materials for the packaging industry, reduce the original production costs, and have both economic and ecological benefits.

With the increase in the amount of packaging waste, the cost of waste disposal has been rising, and increasing the recycling of packaging waste is a general trend. However, in the rapid development of packaging production, China still has a large gap with developed countries in terms of waste management, disposal and recycling.

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.

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 a rate of 12.5%-30% per year. According to research data, 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 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. 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 to produce diesel and gasoline that meet the national standards, and the oil production rate reaches over 75%. Liquefied gas and carbon black can also be recycled if necessary equipment is installed. By changing the catalyst, it can also produce chemical products such as toluene, xylene, and pure benzene.

In addition, waste plastics (including PE, PP, PVC, PS) and filling mixtures (including a variety of urban and rural wastes such as activated carbon waste, crushed animal and plant waste, weathered coal, humic acid and other powders) together constitute a fertilizer capsule. The cost of membranes is only about 300 yuan/ton more than ordinary compound fertilizers. This is an environmental protection project that changes "white pollution" to "green fertilizer" and can absorb a large amount of packaging waste.
