The British supermarket recently introduced the country's first environmentally-friendly plastic bag that can be completely decomposed, and the time for dismantling it has also been significantly reduced to three years. It is hoped that the accumulation of waste plastic waste will be greatly reduced and it will contribute to the protection of the environment. British supermarkets use 4.5 billion plastic bags each year, enough to cover two planets; Britons use an average of 134 plastic bags per person per year, equivalent to 323 per family per year. The British Co-op supermarket was the first supermarket chain in the country to introduce new eco-friendly plastic bags. The fully decomposable plastic bags designed by Syniphony Envivonmental are as tough as regular plastic bags and can be recycled. However, after 18 months, the bags will begin to decompose automatically. The whole process takes about 3 years. Stephens, the company's technical director, said that they added an additive to the new plastic bag that could break down the plastic's tough hydrocarbon structure, leaving only a small amount of organic material, minerals, moisture, and carbon dioxide. In contrast, ordinary plastic bags take about 100 years or more to decompose, even if the so-called green plastic bags currently used in the market, will still leave plastic waste after decomposition, the cost is more expensive than ordinary plastic bags, and the weight is also lower weight. However, one of the members of the “Friends of the Earth” environmental group, Friends of the Earth, worried that general degradable plastics, if decomposed in an oxygen-free environment, would fill the garbage dump and generate methane gas, a greenhouse gas, which is exacerbated. global warming. Strauss argued that since there is air above the landfill, there is no need to worry about methane gas generation, and the environmental protection bag contains very little carbon, which is roughly equivalent to the carbon contained in a piece of bread. The amount of carbon dioxide produced does not affect the environment.
