If compostable plastic products and alternatives like that end up in our blue box recycling facility, they'll probably end up as contamination in many other streams. Sorting is never perfect in these streams. For example, if you combine compostable plastic bags with fossil fuel plastic bags, they're no longer recyclable if there's enough of them in there.
It's the same thing if you put these compostable products and packages into our composting system. If they don't fully break down then, they contaminate the finished compost and make it unsellable.
For the environment, most of these products coming into our system now, as our facilities are designed, would end up pulled out as residue and sent to landfill. They would not be diverted without additional investments in our facilities.
