1.Crystal point The “crystal point” is actually some “excessive polymer”, the molecular weight of the polymer at the “point” is higher than the molecular weight

The essence of biodegradation is that enzymes induce the oxidation and hydrolysis of plastics, resulting in the breakage of the main chain and the reduction

Biodegradable plastics not only have the effect of energy saving and emission reduction in the production process, but also have the characteristics of environmental friendliness

Degradable plastics refer to plastics that can degrade by themselves under natural conditions, and are generally divided into four categories: photodegradable plastics, biodegradable plastics, photo-biodegradable

At present, the global production capacity of biodegradable plastics has reached about 1000kt and is growing at a rate of more than 20% per year;

The public is particularly interested in how long it takes for biodegradable plastics to degrade under natural conditions, and this is indeed the case. However,

At present, the global production capacity of biodegradable plastics is about 1 million tonnes, with an annual growth rate of about 20%-30%. At present, biodegradable

Some reports suggest that biodegradable plastics produce secondary hazards such as dioxins when incinerated compared to conventional plastics. However, biodegradable plastics are a type of
