Redworms are great at composting a variety of material. The list includes food waste such as fruit and vegetable waste, tea bags, bread and other grains, and coffee grounds and filters. Worms also compost paper, cardboard, dry leaves and manure.
After digesting wastes, redworms create worm castings which can be used as an excellent soil enhancement.
Whether it's in a five gallon pail in an apartment, rows in a field or in stacked, commercial bins for a large food service, redworms quietly and happily do their work.
