1. At present, the mainstream plastic degradation technologies in the market are divided into two categories. One is all biobased biodegradable plastics, mainly by finding suitable biological matrices to replace traditional polyethylene plastics, and producing and processing all biobased biodegradable plastic bags through corresponding equipment. Polyethylene plastic bags take 300 to 500 years to degrade into water, carbon dioxide, and soil fertility.
2. Another technique is to add degradable masterbatch to traditional plastics, which can degrade in just 2-3 years.
3. In addition, all biobased biodegradable plastics are relatively good because the materials used in this technology are PBAT or PLA, and most of the raw materials are wheat straw, wood fiber, bamboo fiber, tea, etc. Biodegradable plastic bags are placed at room temperature and constant humidity, and generally begin to degrade after one and a half years. If there are microorganisms, the humidity is 50%~70%, and the temperature is 50 ℃~70 ℃. The degradation begins in 3-6 months, and the degradation products are carbon dioxide and water.
