Turning animal blood to power
JAMES KARUGA
KISERIAN - Maasai pastoralists have found an innovative way to generate biogas: using animal blood and waste from the Keekonyokie slaughterhouse.
The facility in Kenya's Kajiado County uses the gas it produces to generate electricity that powers the meat cold room and processing equipment. It also pipes the gas to local hotels, while the slurry becomes fertiliser for grazing pastures.
Now the Maasai hope to take the project a step further and become the first group in the country to package the alternative fuel into cylinders - and finally make it mobile.
According to project leader Michael Kibue, the group of 320 pastoralists anticipates that by March 2015 they will be selling their Keeko Biogas in six kilogram cylinders. Each should cost around Ksh 700 (US$8), half the cost of conventional liquefied (LP) petroleum gas.
The slaughterhouse can afford to sell its biogas so cheaply because, with an average 120 cows and 400 sheep and goats slaughtered daily, “raw input is assured and at zero cost,” said Kibue.
Even the process of pumping the gas into cylinders costs nothing, he adds, because it's powered by the slaughterhouse's own biogas.
The fuel is also hotter than LP gas “and it is highly combustible, so it allows you to cook faster”, said Erastus
Gatebe of the Kenya Industrial Research and Development Institute (KIRDI), which provides technical support on the Keeko Biogas project. Gatebe said biogas can be as much as 30 to 40% more energy efficient than propane or butane.
