Fossas alternas

IRC has on its website a good photo-sequence on how to build a fossa alterna: “This photo story shows you how to construct a fossa alterna, how to empty it and how to process the compost. After 12−18 months of composting it is safe to empty a fossa alterna toilet and use the compost as fertilizer for your garden soil”. Fossas alternas? Read Peter Morgan’s Toilets That Make Compost Low-cost, sanitary toilets that produce valuable compost for crops in an African context.
