Bioplastics - can they solve our waste problem? Trains of Thoughts
-
- Cultura e società
We have a huge problem. Plastics are littering the environment and they survive here over thousands of years. Companies therefore started to produce plastics that should biodegrade. Therefore, solutions are already existing. But is that really the case? Tests have revealed that even biodegradable plastics do not always dissolve into the environment and can survive years. Corresponding labeling of such bioplastics seems to be misleading. Are we suffering again a severe setback on our way out of our environmental crisis? No – provided that we draw the right conclusions and take the necessary next steps. And the first are taking a closer look – not only on biodegradability.
