  • Ventilation for organic matter breakdown
    Patent number: 6218177
    Abstract: In a container (1) for breaking down organic matter and/or breeding worms, enhanced ventilation is provided via legs (7) which support the container above the ground. Each leg has a longitudinal open channel-like duct which may be formed by making the legs hollow and semi-circular. Each duct communicates with the interior of the container (1) so that any breeze impinging upon the duct causes air to flow upwardly into the container. The effect is enhanced by orienting the legs in different directions and providing air outlets (19) in the lid (6) of the container.
