The emissions of sulfur dioxide and carbon dioxide in my country rank first and second in the world. The annual production of organic waste is more than 50 million tons, and the annual burning and landfilling of plastic bag waste is about one million tons. The carbon dioxide released Above one million tons.
In the production process of bio-degradable plastic bags, its raw materials are mainly produced by consuming carbon dioxide and water (plant photosynthesis turns it into starch), which can reduce carbon dioxide emissions. Conducive to the implementation of the “Kyoto Protocol” is the perfect embodiment of the “green plastic bag” concept. If bio-degradable plastic bags are used to replace the original general-purpose plastic bags of 1 million tons, carbon dioxide emissions can be reduced by more than 3 million tons.
In addition, various plastic bags and biodegradable plastic bags emit different carbon dioxide when they burn. During incineration, general plastic bags will turn into carbon dioxide about 3 times their own weight, while bio-based or biodegradable plastic bags are about twice their own weight. Therefore, the greater the amount of use, the more obvious the difference, and by calculating the total energy consumption of the green plastic bags from the raw materials to the final product, the total energy consumption of the engineering, transportation, and post-use processing can confirm the environmental protection of the green plastic bags.
