The organic waste pref. includes all fermentable rubbish, faecal waste, sewage water etc. produced in the dwelling as well as waste from quick-growing vegetable crops cultivated on roof gardens and surrounding, ground level areas. Solar energy is pref. used to warm the fermenting vessel. Solar energy and fermented organic waste are used to satisfy the power and heat requirement of a community.
