Comment Biodegradable PLA? (Score 1) 121
My county (Maui) is looking at banning polystyrene food containers. We banned plastic shopping bags a few years ago and it's made a huge difference, I used to see plastic bags blowing around, caught in bushes by the side of the road, and in the ocean all the time, but no more.
The thing with the food containers is...most of them will be replaced with PLA. PLA is compostable, where it's in a commercial compost pile over X degrees and with other conditions that help break it down. But what about floating around in the ocean? Obviously it's going to take longer than paper to break down, but has anyone shown how long (or if) it takes to break down in the ocean? A simple google search doesn't reveal anything useful...
