UFRRJ’s compostable toilets; Saving water, producing compost and teaching sustainability at low cost

Abstract

Compostable toilets can contribute to agroecology and socioeconomic resilience against climate
change and other stresses because they are multifunctional. They can help improving the
quality of life from the benefit’s basic sanitation provide to users becouse they are ecological,
low-cost and educational. The goal of this work is to describe five workshops about ecological
sanitation with the construction and management of compostable toilets in the city of Seropédica,
RJ. Over than innumerables formal and informal spaces of agroecological and permacultural
training, these compostable toilets have two expressive results: water savings and manure
production. It is estimated that more than 273,000 liters of potable water have been saved
against fecal coliform contamination and about 1.5 ton of organic manure has been produced
since the project began in 2015.
