The definition of biodegradable; something that can decompose or break down naturally by microbial action, a perfect example is vegetable scraps
Whilst we're not selling veggie scraps, this word is being corrupted by green washing and it's hard to know if any man-made product will every truly break down. Even manufactured rubber and cotton. We're not into green washing so our answer reverts back to 'prevention is better than a cure' and stacked up against creating new materials or working with what we already have around us, we've chosen to make ourselves at home with up-cycling and designing products that are less likely to fall out of your hair
