World Ocean Day | these 10 QoA, you can read biodegradable plastics.

The lack of public understanding of biodegradable plastics is mainly reflected in the lack of awareness of the limitations and potential negative effects of this material.

Biodegradable plastics also need to be recycled, properly disposed of in a specific way, and should not be discarded at will.

"Ten questions and answers on Biodegradable Plastics" focuses on 10 common questions about biodegradable plastics, which aims to enable readers to quickly understand what biodegradable plastics are, what are the difficulties in popularizing and applying biodegradable plastics at present, and what are the feasible solutions.

1. What is biodegradable plastics.

3. How about the relevant standards of biodegradable plastics in China at present?

4. What are the effects of lack of public awareness of biodegradable plastics?

5. How to dispose of biodegradable plastics after use.

6. what is the effect of biodegradable plastics on the recovery of ordinary plastics.

7. In order to properly dispose of biodegradable plastics, what shortcomings need to be made up by the garbage classification management system in our country at present?

8. What are the adverse effects of landfill or incineration of biodegradable plastics.

Development background of biodegradable plastics.

Although plastic was only used in large-scale production before 1950, the fact that plastic itself is difficult to degrade and production is growing too fast has caused human beings to encounter an environmental problem that may last for centuries.

So from the 1980s, scientists began to study whether plastics can be degraded and disappeared by microorganisms in an active environment.

This kind of plastic that can be degraded by microorganisms is what we call biodegradable plastics today.

The market situation of biodegradable plastics is chaotic.

In the past two years, a series of policies and legal documents have been issued at the national and local levels, placing high hopes on biodegradable plastics.

Relevant data show that the production capacity of biodegradable plastics in China is increasing rapidly.

For example, the survey found that some manufacturers confuse the concepts of bio-based and biodegradable. In fact, the word bio-based refers to the source of material components, in other words, bio-based plastics are not necessarily biodegradable.

For example, the biodegradability of products measured in accordance with the relevant methods and standards is not equal to that the test results of biodegradability of products meet the requirements of the relevant compliance standards, but some manufacturers compare the two.

Biodegradable plastics are not the way to deal with plastic pollution. In the past two years, a series of policies and legal documents have been issued at the national and local levels, placing high hopes on biodegradable plastics.

In November 2015, the United Nations Environment Programme released a report entitled "Biodegradable Plastics and Marine waste: misunderstandings, concerns and impacts on the Marine Environment", which made it clear that the promotion of the use of biodegradable plastic products, will not significantly reduce the amount of plastic waste entering the ocean.

Peter Kershaw said that the key to dealing with plastic pollution is to change people's behavior, and biodegradable plastics are not the way out.
