Speaking of, don't they use plastic liners to keep the pollutants out of the groundwater? Filling landfills with a chemical to break down plastic could backfire badly.
pretty sure we could come up with another type of liner
It'd be an unusual landfill to start with, because caterpillars generally don't like anaerobic conditions. More like a compost pile that's kept well-aerated.
It seemed like there was a desire to mass produce the chemical that the caterpillar uses to dissolve the plastic, not to use actual caterpillars.
