According to the "Research Report on the Environmental Impact and Recycling of Plastic Packaging in the Takeaway Industry (2021)", since 2015, China's takeaway industry has begun to experience explosive growth, resulting in an increase in the consumption (waste) of plastic packaging from 57,000 tons in 2015 to 574,000 tons in 2020. The pressure on the ecological environment cannot be underestimated.

The essence of plastic pollution is that plastic waste leaks into the natural environment such as soil and water bodies and is difficult to degrade, causing environmental hazards such as soil damage and microplastics.

Can plastic pollution be solved from the plastic production end? What is the principle of plastic degradation? How is it that only water and carbon dioxide are produced after plastic degradation? Recently, Poster News reporters interviewed Shandong Dawn Zhoushi Packaging Co., Ltd. and Shandong Dawn Degradable Materials Co., Ltd. under Dawn Group to reveal the secrets behind solving plastic pollution from the production end.

It can be completely decomposed into water and carbon dioxide within 180 days in a composting environment. The so-called composting environment mainly refers to high temperature and high humidity. Biodegradable plastic bags can be degraded by microorganisms such as bacteria, mold (fungi) and algae existing in nature. Ideal biodegradable plastics have excellent performance and can be completely decomposed by environmental microorganisms after being discarded, becoming a part of the carbon cycle in nature.

In terms of safety, some areas do not have composting capabilities, and when incinerated, no toxic substances such as dioxins will be produced; in terms of renewability, its components PLA and starch are extracted from corn starch and are sustainable.
