Development of a fully biodegradable brick in the “Lego-like” shape for building pit latrines. Large-scale tests are being conducted in Brazil and Ethiopia.
To be able to disseminate the Lego-like brick, we decided to create an Eco-center in a community school in Brazil. The idea is to teach the students, their parents and the community around the school how to manufacture the Lego-like bricks. At the same time we would like to a sense of community and more important create a conscious ecological way of thinking.
Create an easy, low cost and user-friendly technique for building pit latrines.
The estimated cost for each brick is less than US$0.04/brick. It does not require any special condition to manufacture the brick, just mix the bio-plastic and soil compress using a manual press and let it dry under the sun.
