What I am doing though, is using biodegradeable coffee cups and lids as shelter for the mealworms, because if they eat and digest those, they're food-grade and biodegradeable anyway so the break-up will only accelerate composting. Food-grade bioplastic waste could definitely be accelerated and reduced using this method. Just slice it up finely with a scissors and add to the normal bedding. #Mealworm #Composting: Turning coffee-cups into chicken snacks the lazy way. :)
