NAIROBI (Xinhua) --
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.
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
“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.
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.
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.
