"Lego" like Sanitation System: Pit Latrines Made of Biocomposites

Antonio Avila of Universidade Federal de Minas Gerais in Brazil proposes to develop building blocks made from biocomposites that will replace conventional brick and cement constructions for pit latrines. The team will test these building blocks strength and their rate of biodegradation to determine their suitability for building latrines that will decompose once the pits are filled, allowing for the eventual reintroduction of the land for farming and other community uses.
