It was learned that Nanjing experts recently developed a biodegradable lunch box and plastic film. This lunch box is buried in the ground and can be converted into carbon dioxide and water in a short period of time, which greatly eases the pollution pressure in Nanjing.
According to Professor Zhang of Nanjing Huanlv Company, this kind of biodegradable tableware is made of corn, starch and six kinds of plant fiber materials. After the snack box or film made of new materials is buried in the ground, it can be “sheltered†by microorganisms in the soil and eventually become carbon dioxide and water, and it does not pollute the environment.
Shi Yuanchun, academician of the Chinese Academy of Sciences, made a special inspection and said that the technology is at the leading domestic level. At present, the technology has attracted the attention of South Korea, Japan and European countries. Nanjing authorities allocated 300,000 yuan to push it into the market. It is reported that the ultimate "outcome" of urban garbage in China is not bare stacking or shallow burial. As a result, extremely fast-degrading white snack boxes and plastic films not only consume petroleum resources, but also damage the quality of the soil. In the Xinjiang region, cotton has been found to reduce production by more than 10% due to soil residual agricultural film. Nanjing needs about 200,000 to 300,000 fast food boxes per day and 600 to 9 million per month. In recent years, after Nanjing introduced a white "ban", many environmental protection appliances such as paper boxes have become popular. However, polyethylene or polypropylene plastics that have been degraded for more than 200 years are still considered to be "half-degraded" and still cause environmental pollution.
