The unique design of the Hungry Bin creates an ideal living environment for compost worms. The worms convert organic waste into worm castings and a nutrient-rich liquid, both high-quality fertilisers. The liquid drains freely from the bin and into a tray placed below it. The tapered shape of the bin compresses the castings, encouraging the worms to move to the surface layer to access fresh food. Compressed castings are easier to handle and largely free of worms. Worms sold separately.
