Because of its rich characteristics, plastics are widely used in various fields. However, the "white pollution" caused by the proliferation of disposable plastic products has become a headache in the world.
According to statistics, disposable plastics now account for 40% of global plastics production annually, with about 128 million tons. The recovery rate of most of these plastics is very low, some of them require several hundred years to degrade, and some cannot be degraded. Plastics will gradually turn into particles and flow into the ocean. It is predicted that by 2025, marine plastic debris will reach 250 million tons. Countries all over the world have declared war on plastics and have issued various laws and regulations to limit their use and disposal. Research institutes are also working hard to study new materials that can replace plastics.
Recently, the Green Chemistry Research Center at York University in the United States has used molecular technology to create a new generation of bio-based polyesters. Polyester is one of the main raw materials for clothing fibers and cling film, and it is usually difficult to completely decompose. And plant polyester, It is made entirely of plants, so it is recyclable and can be completely degraded. The person in charge of the study stated that although this technology is still in the development and research stage, it is hoped that the plastic will be transformed from garbage into a recyclable resource.
