Bio-sanitation toilets have been launched in Kenya in order to eliminate pit latrines which have been blamed for contaminating ground water, the inventor said on Thursday.
Biogas International Operations Manager Josephat Chege told Xinhua in Nairobi that the Bio-sanitation toilets are more hygienic because the human waste is deposited in bio-digesters and converted to biogas and fertilizers.
“We want the bio-sanitation toilets to replace pit latrines in order to improve the overall sanitation in the country,” Chege said during the Kenya Renewable Energy Conference and Exhibition.
Government data indicates that over 70 percent of Kenya’s population uses pit latrines and is yet to adopt the modern antiseptic systems. The pit latrines have also been blamed for the spread of water borne diseases such as cholera.
Chege said the bio-sanitation toilets are ideal for a developing country such as Kenya because they safely evacuate and covert the human waste into biogas and fertilizer.
Biogas can be used at the household level for cooking and heating of water.
A bio-sanitation domestic system that supports family of 10 people retails for 610 U.S. dollars and the investment can be recouped in 10 months through savings in the purchase of fire wood or fertilizer.
According to Biogas International, the slurry from the bio-digester is organic fertilizer that remains on the soil for about two years.
The biogas is also an environmentally sustainable solution to the use of charcoal that has led to the rapid deforestation of Kenya.
In many rural households, women spend between three to four hours daily searching for firewood and so the Bio sanitation toilet will help to improve the productivity of women. Enditem
