Development Status of Biodegradable Plastic Bags

Environmentally friendly plastic bags are short for various biodegradable plastic bags. With the development of science and technology, various materials that can replace traditional PE plastics have emerged, including PLA, PHAS, PBA, PBS and other polymer materials. Environmentally friendly plastic bags have been widely used: supermarket shopping bags, continuous roll fresh-keeping bags, plastic film, etc. have large-scale application examples in China. Various countries use PLA (polylactic acid) to replace traditional plastic bags and have achieved good results.

Paper Straws VS PLA Straws

With the official implementation of the plastic ban in 2021, the traditional plastic straws commonly used in the market have been gradually replaced by PLA degradable straws and paper straws. Although paper straws and PLA straws solve the irreversible damage to the environment caused by plastic straws, they have distinct advantages and disadvantages under the existing technical conditions.

How to Turn Waste Agricultural Film into Treasure?

Due to the use of agricultural plastic film, the temperature and humidity of the soil are effectively controlled, the loss of water and nutrients is reduced, and the high and stable yield of crops is promoted, thereby increasing the benefits of agricultural production. But at the same time, due to the one-time use of plastic film, a large amount of residual film remains in the soil every year. Plastic mulch is difficult to degrade in nature. These mulch fragments can form a barrier layer in the soil, blocking the flow of water, gas, and fertilizer in the soil, causing the soil structure to harden, seriously harming the ecological environment, and causing white pollution. Therefore, solving the problem of soil pollution by residual film has become the top priority of mulching cultivation technology. In order to solve this problem, the research on degradable plastic film came into being.

Wanna Know More about Degradable Tableware?

Plastic waste spreads across the oceans and the atmosphere, endangering marine ecology and exacerbating the climate crisis. For this reason, governments around the world have successively issued “plastic bans”, and the industry has turned to compostable or biodegradable plastics instead. Use as disposable packaging or cutlery materials. As a consumer, when using these “greener” options, you will feel better, as if you have no worries about throwing away your trash – however, do you really know about degradable tableware?

Classification and Right Way to Use Plastics

The plastic product recycling label was formulated in 1988 by the “Society of the Plastics Industry” (now renamed the “Plastics Industry Association”). This set of signs stamps the plastic material identification code on the container or packaging, from No. 1 to No. 7, so that people can easily join the ranks of recycling without having to bother to learn the similarities and differences of various plastic materials. Each plastic container has a small ID card – a triangular symbol, usually at the bottom of the plastic container. There are 1 to 7 numbers in the triangle, and each number represents a type of plastic container. They are made of different materials, and there are also different taboos in their use.
