NedCompost Earth TubsThe NedCompost composting facility comprises two 1,000 gallon Earth Tubs, two bicycle trailers, ~30 5 gallon buckets, and 2 bicycles. Each Earth Tub can process up to 150 lbs of biomass per day. They are basically large cyclindrical composters with a motorized auger mixer. The auger runs on a track on the lid of the Earth Tub and the lid must be rotated by a human walking around it to thoroughly mix the compost. A full batch of compost can be processed every 20-40 days.
