Is it possible to make plastic bags from oyster shells?

Yes, it is possible – at least partially. After a great deal of searching, Swedish and Canadian researchers have found a way to make granular powder from oyster shells. By blending 25% granular powder from oysters with 75% recycled plastic, a plastic mixture called Trio Biomarine is produced.

Oysters are fantastic animals that positively affect water quality since they ventilate and clean the water. The oyster shells used to make the plastic bags are a residual product from the food industry. The shells are washed and crushed at very high temperatures to clean them completely. The shells are then turned into granular powder and finally plastic.

Polarn O. Pyret will now gradually start using Trio Biomarine in our plastic bags, thus making them a little more sustainable and kinder to the environment. Oysters are a renewable raw material, and carbon dioxide emissions are 75% lower than when manufacturing regular plastic bags.

The plastic bags look the same as previously, but have a different feel – they are slightly “grainy” or “rough”. Check next time to see whether you are holding an oyster bag!
