NON–FLUSH, totally organic and self-emptying portable toilets which make use of hungry earthworms are being made in Knysna.
Knysna entrepreneur Adrian Wilson-Forbes said two test toilets at the Pezula resort had been operating successfully for the past seven months without any need for servicing.
This self-sustaining ecosystem houses earthworms in so-called worm houses made from recycled plastic in a container below the toilet bowl. The worms gobble up the solid waste and recycle it to produce compost.
Wilson-Forbes said: “The solids sit on top and are digested by the earthworms, which multiply or decrease in number according to the amount of food available.
