It’s a project of engineers without borders, which expect to introduce this technique next year in Tanzania. In addition to coal, the process produces biogas. Students of the Technical University of Berlin have developed a process to produce biological carbon from human feces, it announced Monday the Organization engineers without borders. This technique will be put into practice between July and September in a greenhouse in Berlin and if successful will be introduced year coming in Tanzania, said Volker Eiselein, spokesman for the organization. Coal serves as fertiliser for crops and because of its porous properties is suitable as water tank and to protect from erosion, said. Thanks to this new technique, feces may be purified of hygienically and charred at high temperatures. Parallel to the process of carbonization occurs biogas plant also designed by students. The remaining substrates will be mixed with purified droppings to be processed, explained Eiselein, who pointed out that the heat needed for this process will be extracted from the biogas plant. Office in Berlin of engineers without borders, which since 2006 focuses his work on the Tanzanian’s Kaguera region, has carried out several projects of water and energy in collaboration with the Organization Mavuno Project.
