I don’t have a problem with cleaning tbh. It’s not required here but I just feel icky if I put a yogurt stained container into the bin.
With burning, it must be done at very high temperatures to ensure the resulting gasses get burned as well. Here I generally ment collect plastic and send it to a facility which has furnaces which can accommodate this kind of waste (like rubber tires).
I take 95 over 100 but if you want a plastic dick, have at it haha
