Water-degradable plastic synthesized by starch and cellulose
Marine pollution has become a hot topic in recent decades, and it is gradually threatening the safety of marine life and humans.
How is marine pollution caused? With the development of the world’s industry, marine pollution has also become more and more serious, causing great changes in the local marine environment and the trend of continued expansion. In order to save costs and time, the factory dumped a lot of waste into the sea, which caused the accumulation of marine debris. The most important thing is the accumulation of plastic garbage because traditional plastic scattered in nature is difficult to degrade by itself. Therefore, the discovery of marine biodegradable plastics has become an important task for contemporary scientists.
Previously, two Japanese companies jointly developed marine-degradable plastic, but the low output and poor quality of this plastic made it difficult to meet the normal demand of the world market. These disadvantages led to the limited use of this product. Therefore, there is an urgent need to develop a low-cost, high-yield, good-quality product for us to use, to clear the extent of marine pollution, solve the problem of garbage accumulation, improve our marine environment, protect marine life, and avoid marine life caused by accidental eating. Die.
Among them, two professors at Osaka University led a team to study this issue. As we all know, starch and cellulose are almost everywhere in nature and widely distributed. Starch is the main component of carbohydrates, and cellulose is the main component of plant cell walls. This means that in the research, the water-resistance of starch needs to be improved first so that the synthetic plastic can be perfect. The raw materials are not only cheap, but the manufacturing process is simple, the cost is low, and the time is short. If this R & D product can be put into the market, it will definitely alleviate the problem of marine pollution, reduce marine debris, and give us clean sea effectively removed threats to marine life and human health.
For this technical achievement, all major scientists and laboratories should make effective use of those low-cost, easily-available and widely-existing substances as far as possible, so that the emission of harmful gases can be reduced, to protect the global environment and reduce the destruction of nature.
In the face of the deteriorating global environment, the protection of nature has become a general trend. In accordance with the principle of sustainability, the available waste should be recycled to minimize the harm to nature. After all, the earth is our only home now. It should be cherished.
Using starch and cellulose to synthesize degradable plastics, I believe this technology can effectively solve the environmental pollution problem. The current research direction is not just to find products that little harm to the environment, but more importantly, to discuss raw materials, pay attention to the use of waste, and the use of widely distributed substances, follow the requirements of sustainable development.
