In the face of increasingly serious plastic pollution, especially the one-off plastic waste, some industries such as express delivery, take out and other related policies began to propose the use of degradable plastic particles instead of traditional plastic as a treatment scheme. However, at present, there is a lack of scientific and clear definition and understanding of what is the highly respected degradable plastic particles and how to deal with disposable plastic waste in China. Can degradable plastics really replace traditional plastics as saviors? Here's a look at degradability with you.
When we talk about so-called environmentally friendly degradable plastics, we usually talk about "biodegradable plastics". Biodegradation refers to 100% of the components that can be biodegraded into inorganic substances, water and carbon dioxide, but non biodegradation means that they will not be biodegraded into inorganic substances or water and carbon dioxide. Among them, plastics can be divided into biological base and fossil base according to raw materials. Bioplastics are plastics made of biomass (including animals, plants and microorganisms); fossil plastics are plastics made of fossil materials. Traditional plastics can't be biodegraded, they are made of stone. At present, we are talking about more biodegradable plastics, which refers to the c-quadrant data, not only based on biomass, such as corn starch or sugarcane, but also can be biodegraded
Can biodegradable plastics really degrade in nature?
Previously, experts from China post industry introduced that 200 plastic bags commonly used at present need to be degraded under natural conditions, while biodegradable plastic express packaging bags are discarded under natural conditions (such as soil, sand, etc.) and specific conditions (such as composting, anaerobic digestion, etc.), while water-based culture medium), natural degradation is caused by the role of microorganisms in nature. After six months, it can be completely synthesized into carbon dioxide, methane, water and mineralized inorganic salts containing elements, and the impact on the natural environment can be ignored.
