Packaging product "green" process (2)

At present, the annual output of packaging waste in China is about 16 million tons; 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.

At present, the reuse rate of paper, iron, aluminum and glass containers in Switzerland averages over 86%; the German tinplate recovery rate is 50%, 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.

— — The recycling of packaging materials has obvious economic and ecological benefits. 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; Annual recycling of 1 billion glass bottles can save 49,000 tons of coal, 38.5 million tons of electricity, 49 thousand tons of quartz stones and 157,000 tons of soda ash, and recover all kinds of iron barrels. 40 million, can save steel 48,000 tons; one year recycling packaging fabric 100 million meters, can save 15,000 tons of cotton; recycling all kinds of sacks 3000, can save 22.5 tons of raw hemp, more than a few The total value of the company reached several hundred million yuan.

— The continuous growth of packaging waste production provides sufficient production resources for recycling. 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.

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%. If necessary equipment is installed, liquefied gas and carbon black can also be recovered, and by changing the catalyst, toluene, xylene, and benzene and other chemical products can be produced.

The best choice to promote green packaging

Although the government and the packaging industry sector in China have adopted a series of remediation measures and achieved certain results, the pollution status of packaging is still quite serious. In the face of severe realities, the Chinese government has adopted a series of measures. In 1979, the Chinese government issued the "Environmental Protection Law of the People's Republic of China" (for trial implementation), and environmental protection work has a path to follow. Recently, relevant departments in China have formulated regulations on packaging and packaging waste. While establishing and improving laws and regulations, the government has adopted various economic measures. Through the use of economic measures, the situation of packaging pollution has been improved. However, to promote green packaging fundamentally, the government should impose a package pollution tax.

Environmental pollution is a major social hazard in today's society. It is also one of the important reasons that affect China's sustainable development. Population, economy and environment are the most important factors in sustainable development. The population is the center, the economy is the foundation, and the environment is the premise. The introduction of packaging pollution tax can reduce packaging waste, and also help reduce resource consumption, and make the national economy move toward low input, low consumption, high quality, and high quality through extensive economic growth with high input, high consumption, low quality, and low efficiency. Efficient intensive economic growth mode is developed so as to realize the social sustainable development strategy.

In the 21st century, green industries, green enterprises, green technologies, green products, green trade, and green consumption will become the main bodies of the society. In the course of their own development, enterprises will lose the market if they ignore this development. Actively developing packaging materials and products that do not pollute the environment, are easy to recycle, and do not cause public harm to the society are urgent issues that must be addressed before us. The packaging industry must carry out a revolution in the development of green packaging technology. The introduction of packaging pollution tax can enable enterprises to shift from “universal” technologies that maximize profits, to “diversity” technologies that take ecological, resource, and environmental considerations into consideration, enabling companies to combine short-term and long-term interests in production. Non-hazardous technology, energy saving and consumption reducing technologies are taken as the technological selection direction for enterprise development.

At present, developed countries and some developing countries have already imposed or are about to introduce a package pollution tax. For example, at least 50 cities in Germany are considering the collection of “packaging tax” and they are supported by the court; Italy implements the “Plastic Bag Taxation Law”, which stipulates that every plastic bag pays 8 cents, and each store sells a plastic product worth 50 lire. Bags are subject to a tax of 100 lire; at least 22 states in the United States are considering implementing a packaging tax or the Waste Disposal Prepayment Act (AOF), and nearly half of the states have banned the listing of food plastic packaging that cannot be disassembled and restored. . The City of Seattle has stipulated that each household transports four barrels of garbage each month to pay $13.25 in fees. It can be seen that China's introduction of packaging pollution tax has been internationally used for reference. It will be an effective rectification of packaging pollution. New initiatives.
