The Earth Lung is a part of the biological water purification system that purifies the blackwater from the Green Solution House. The Earth Lung’s role is to remove odourous biogas which is generated during the anaerobic digestion stage of the water cleaning process. The design is simple – biogas is fed into the bottom of a plant box, which has a soil buildup that secures a porous composition. The roots of the plants consume the gases, which also act as fertilisers, promoting growth.
