Biodegradable tableware is those products seemingly like disposable plastic fast-food dishes, cutlery, which will not cause white contamination to the environment after being thrown and decompose in the soil. For example, disposable biological degradable container, cup and plate, lunch box made by using corn starch as raw materials.
The Significance of Developing Bio-degradable Plastics
Photodegradable plastic only degrades under daylight. The plastic which can degrade into small molecule compounds into the ecological cycle is just a very small part, the vast majority of plastics are just gradually disintegrating into fragments or powder, may be invisible to the naked eye, but the situation that they are absorbed by microorganisms in the soil for a long time is not yet clear. Part of the plastic waste is buried in the soil or underground as a landfill, which do not degrade due to the lack of light or hypoxia, lack of water and, only making the pollution from visible to invisible, and bring big potential hazards to the ecological environment. Therefore, the development of bio-degradable plastics will have a positive meaning to the entire biosphere.
Reasons for Difficult Promotion of Degradable Plastics
However, despite the degradable plastics research and reports, many of the specific problems cannot be solved; the promotion is extremely difficult, and the outlook is not optimistic. Reasons: First, because the biodegradable plastic bags load-bearing capacity is low, which cannot meet customer requirements of loading more things and repeated use; Second, biodegradable plastic bags are faded yellow, low transparency, giving a sense of not clean enough and ugly, which is not assured to use; Third, the price is high, businesses are given free, so the cost is difficult to accept.
Disposable Tableware is Produced to Take Instead of EPS
In another example, to solve EPS fast food clamshell boxes pollution problems to the environment, which is to replace paper lunch boxes. However, due to the presence of the following reasons, it is extremely difficult to promote: First, EPS is high strength, light weight, good insulation; Second, EPS price is 1.5 to 2.5 times as the price of paper boxes; Third, even with the degradation PP boxes, its performance is worse than EPS. Recently, the relevant departments require using plant fiber to produce disposable tableware to take instead of EPS. However, since the plant fiber tableware the use hot polymer sol in the molding process, it still exists handling problems and residual pesticide content in the plant fiber tableware control problems.
www.biodegradabletableware.com.cn is one of the biggest disposable tableware manufacturer in China, which is speclialized in research, development, production and marketing of eco-friendly paper tableware and packing materials.
