HC Plastics News: The “plastic limit order†has been implemented for nearly ten years. The slogan of the banned free plastic bags in the farmer's market proves that it has existed. The demand and usage of plastic bags in China have not seen true in the past ten years. Reducing, the current rise of the express industry and the take-away industry has intensified the use of plastics. It may have a certain effect if it is banned. At present, there are no scenes in the streets of big cities where the garbage bags are flying all over the sky, but there is really no other. Have you chosen?
What is the problem currently facing?
The main reason why white cannot be eradicated is that plastic bags and plastic lunch boxes have become people's living habits, mostly disposable items, but most of them cannot be effectively treated. Currently, the materials used in lunch boxes are mostly PP (polypropylene). ), the rapid development of transparent agent technology today also has good transparency, and has better recycling performance than other plastics, but currently faces difficulties in recycling, and there is no uniform additive standard for disposable lunch boxes on the market. This is especially true for plastic bags, so the “plastic limit order†can only be a stopgap measure, and it cannot be finalized until there is a completely suitable substitute.
What is degradable plastic?
Degradable plastics is already an old topic. In the last century, many scholars have proposed the idea of ​​degrading plastics. It means adding a certain amount of additives to the production. There are many bio-based materials, which make the stability of the plastic structure decline. It is a material that is easy to degrade in the natural environment. Generally speaking, it can be called degradable plastic when it reaches 60%. There are several common degradable plastics: PLA (polylactic acid) and PBS (polybutylene succinate). Ester), PCL (polycaprolactone), PHA (polyhydroxyalkanoate), PBAT (polyadipate/butylene terephthalate), and PPC (polypropylene carbonate) of recent fires, Good degradation performance, but the general problem is higher cost, the average price of degradable plastic lunch box is 2-3 times that of ordinary PP lunch box, and the paper environmentally friendly lunch box is 4-5 times price. The hotel will of course choose A more affordable ordinary plastic lunch box.
Degradable plastics prospects
New products for degradable plastics emerge in an endless stream, and more and better solutions have emerged in various fields of degradable plastics applications. They have good market prospects in food, agriculture, medicine, etc. At the current stage, for degradable plastics. The main research direction is biodegradable plastics. There are also many discoveries and ideas for biodegradable plastics at home and abroad. There are many new products and new discoveries by international chemical giants such as BASF and authoritative research institutions from various countries.
In the future, faced with increasingly serious environmental problems, regardless of the current "plastic limit order" is a piece of paper, or a nameless, environmental problems will not reach the end, disposable plastic products that are difficult to degrade will eventually be banned, regardless of plastic products manufacturers, It is still the delivery industry, and the emerging industries related to it will eventually become standardized and standardized. At present, Jilin and Jiangsu have introduced regulations prohibiting the supply of non-degradable plastic products. It can be seen that the degradable plastic products are widely available.
