The Genie in a Bottle
Growing up, I always dreaded to enter my grandmother’s kitchen in the village. She used firewood to cook: There was such a dark, thick smoke in the room that I couldn’t breathe or keep my eyes open. I really don’t know how my grandmother could spend hours and hours in there, every day, for so many years. And unfortunately, my grandmother is not an isolated case. More than 90 percent of Kenya’s population uses firewood, charcoal or kerosene for their daily cooking needs.
I always dreamed that clean sources of energy would make Kenyans more independent and less exposed to the serious health risks posed by fossil fuels. In rural areas, most women like my grandmother rely on firewood; its consumption not only depletes our forests but also emits hazardous smoke that causes indoor pollution and eventually respiratory illness. In areas where firewood is scarce, women have to use cow dung as fuel, an option possibly even worse in terms of pollution. Urban areas are affected too: The poor rely mostly on charcoal, another biomass that has the same negative effects and health risks of firewood.
Cleaner fuel options have already been developed but are often too expensive or too difficult to transport across the country to be adopted by a large part of the population, especially by the 40 percent of people at the base of the pyramid.
So what can be done? How can we make clean fuels more affordable and accessible?
I first heard about bottled biogas when I visited a "green" slaughterhouse in Kiserian, Kenya. I was really impressed: My dream of a cleaner, more affordable and easily accessible fuel was right there before my eyes.
The Keekonyoike Slaughterhouse found an innovative way to produce affordable biogas and package it for distribution all around the country. Using a special bio-digester, this business can turn blood and waste from a community-based Maasai slaughterhouse into biogas for cooking. To facilitate transport, the firm stores the fuel in recycled cylinders and used tires, reducing even further the environmental impact of the operation. Just to give me a better idea of the "green" potential of his business, the manager told me that this first biogas plant is expected to cut methane emissions by more than 360,000 kilograms per year (the equivalent of almost 2,000 passenger vehicles).
Indeed, "bottled" biogas (biogas compressed into a cylinder) has huge potential in Kenya: Farmers can directly produce it, recycling the waste from their farms; can use it for their cooking needs; and, thanks to the bottling process, can sell the excess on the local market, generating income while saving the environment.
