Cities are living organisms with huge digestive inefficiencies, such as waste accumulation and lack of housing. Curadores da Terra (Earth Curators) has developed an innovative system that transforms waste into manufactured materials for housing, helping cities' healing process. The core innovation consists of a patented technology that combines waste with organic resins in order to produce renewable construction materials, which are then used to build sustainable and affordable houses through a construction process that we also developed and tested. We recently partnered with RAD Ambiental to create an industrial plant (the Clean Plant) in order to standardize and produce at scale; we also developed three Zero Waste Laws, paving the way to national scale replication.
