Bio-Latrines

Wanzala Bahati Justus reports on Bio-Latrines in Kibera Kenya:

The bio-latrine uses the technology of anaerobic or airless digestion to transform human waste into fertilizer and gas suitable for uses like cooking, heating and lighting,” said Malcolm Ormiston, a Nairobi-based engineer and owner of Globology Limited.Consequently, the community is able to properly dispose human waste and at the same time reduce pollution and environmental degradation.Ormiston said that the bio-latrine uses standard biogas-system designs commonly found in Asian countries such as China, India and Vietnam. But the marked difference between biogas digesters and bio-latrines is that latrines use human waste instead of animal waste.
The toilet facility and digesters are constructed using conventional building materials and require little maintenance.The systems are scaleable and can thus cater for various sizes of populations, ranging from small settlements to large institutions.
“They are ideal for both urban and rural schools and health centers where cooking energy is required,” said Ormiston
