Introduction: Biodegradable Materials

How do you think

of your life now? Maybe it’s peace and comfortable for us. With the human history development, of course, our life has changed a lot. Because we find the right development way, we try to find the newest technology and use this new technology to change our life to be much better.

In these technologies, the technologies of plastic, including plastic materials, plastic mould, and plastic products, are widely used and especially very important in our life. It can be used in the car, plane, wear, sport and household and so on.

Plastic has some good advantages. The plastic products can be very light and hard which can replace the metal. When the weight of car or plane is decreasing, the speed of them will increase. When will go out for a trip, these plastic products can be easily taken. So it’s very convenient for us.

But as we all know that the plastic materials, like PE, PVC, are the non-biodegradable materials, which can lead to the pollution for our environment. Such as the plastic bag pollution is very serious in the world. So it’s eager for us to find the biodegradable materials to replace the non-biodegradable materials and control the pollution.

The biodegradable materials have three different kinds as follows.

First is the poly lactic acid biodegradable material which can be simply called PLA. Poly lactic acid can be decomposed into lactic acid and acetic acid in biological body. By the function of metabolic enzyme, they can finally turn to carbon dioxide and water.

Second is the starch plastic material. Starch can be completely decomposed into the carbon dioxide and water in various environments.

Third is the light degradable plastic material. With the light, these materials can be completely decomposed into carbon dioxide and water.

What’s more, the carbon dioxide and water can be reused and are no harm to the environment. Now, these materials have been used to produce the bottle, cup, plastic film, clothes, tableware and so on. I believe that the bag pollution can be solved in the later time. And we can enjoy more health products.
