Working with the American NGO  "UrbanBioRecovery: Digesters for Development" (originally called "Solar Cities Solutions" from 2012 through July 2014)  Solar CITIES e.V. intern Jorma Gorns joined T.H. Culhane on a project bringing Puxin 10m3 biodigester molds to sites in Rio De Janeiro.  The initial work was done by Solar Cities Solution's "Biogas Education Team" members T.H. Culhane, Yair Teller and Marcello Ambrosio, working with Dr. Gail Richardson, in conjunction with Architecture for Humanity's architect Luis Felipe Vasconcellos. Three digesters were built at the site of a new elementary school and day care in Niteroi, two 4m3 units for the school's toilet wastes and one 10m3 unit for the cafeteria wastes.  A constructed wetland was built alongside the school to further aerobically phytoremediate the effluent from the humanure digesters. The effluent from the food waste digester can be used directly in the school garden.
