Question: how long does it take for plastic to biodegrade?

Dan Day answered on 6 Oct 2022:

It depends on the plastic in question. Some go very quickly in a matter of days. But many take thousands of years which means that they can accumulate in the environment. We have done some work in my project where we have shown that we can tailor biodegradation rate by playing with the chemistry https://www.champion-project.eu/
