Furthermore, petroleum plastics do not biodegrade, creating a ballooning litter problem on land and sea as global plastics production has risen to about 250 billion pounds annually.
But will conversion to a plant-based substitute really solve everything? Considering a few key questions should help us ferret out some of the critical issues that would need to be addressed before we can give bioplastics a thumbs up or down.
Is bioplastic technology ready?
Even though you won’t find them on major supermarket shelves, some forward-looking companies have figured out how to make disposable plastic items (such as cups, bowls, plates, clamshells, Read the rest of this entry »
