http://magazine.good.is/articles/ugandan-abattoir-waste-biogas

In Kampala, Uganda, a large abattoir was running on diesel generators (because even though Kampala is the capital city of Uganda, it suffers from irregular electricity) and dumping its meat waste into the bay. A professor at Makerere Unversity’s Department of Biochemistry and Sports Science (ed: I LOVE that combination of topics!) proposed using the meat waste to make biogas.

As of last month, Kyambadde and the abattoir had managed to integrate recycling systems into the slaughter process, creating between 10 and 25 cubic meters of gas per day to power security lights, freezers, and refrigerators, as well as producing fertilizer-ready byproducts. The recycling process itself relies on solar panels to heat water in biomaterial digesters, converting organic material into methane. At present, the gas has cut diesel bills by 90 percent per month and reduced their overall monthly energy expenses by up to $2,800—a fair sum in the local economy. And that’s with just 40 percent of the facility hooked up to the system. Kyambadde and others believe they can soon scale up to 100 percent integration, taking the slaughterhouse off the grid and even producing excess energy that they can sell off for profit.



Elsewhere in Africa, Maasai clansmen are doing the same thing, and selling the biogas to neighbors in canisters.

I am surprised that the slaughterhouse waste is good for that sort of thing.
I had never thought of using animal products In a biogas generator.
I'm also surprised it wasn't already being recycled into chicken feed or pig feed.

They say the next step is to build new slaughterhouses out in the rural area, closer to where the animals are grown. This could lead to business like the Maasai selling fuel to neighbors for cooking, etc. Get them some solar lights and who needs to move to the city?
