The cost of biodegradable PLA stics needs to be reduced, and the price of biodegradable products should be reduced to civilians

PLA stic is a great invention of the last century. It has only been more than 100 years since the invention of PLA stic, but its degradation cycle is as long as 400 years. Traditional PLA stics cause serious white pollution problems and bring a huge burden to our living environment. The research and development of biodegradable PLA stics is The problem of white pollution offers a solution.

For example, the following biodegradable PLA stics: The material properties of PHA (polyhydroxyalkanoate) are similar to traditional petrochemical PLA stics, and can re PLA ce more than 50% of petroleum-based PLA stic applications. It can be used to make PLA stic bags, PLA stic tableware, PLA stic bottles and so on. More importantly, bio PLA stics degrade quickly and can be degraded within 3-6 months in the soil. At the same time, other microorganisms can reproduce faster after eating this bio PLA stic, making the land more fertile. However, at present, polyethylene and polypropylene are the two most common petroleum-based PLA stics in the world, with an annual production capacity of 130-140 million tons. The annual production capacity of PHA is only about 50,000 tons, which is only a fraction of petroleum-based PLA stics. The key reason is the cost, the PLA stic is too cheap, the production process is too mature, and the usage is too large. Therefore, in order to popularize bio PLA stics, it is necessary to reduce the cost, that is, “how to fatten some microorganisms cheaply”.
