Sanitation and cooking fuels are two of Africa’s biggest problems. Many of Africa’s big cities have a bad reputation for poor waste management. Due to unregulated dumps and improper drainage and sewage systems, collected human waste is most often dumped into the sea.

On the other hand, cooking fuels are also a major handicap for many Africans. Due to a heavy dependence on firewood and charcoal as cooking fuels, the continent’s forests are fast depleting.

In the face of these two daunting challenges, a team of entrepreneurs in Accra, the capital of Ghana in West Africa, have come up with an interesting way of converting smelly human waste into an odourless, healthy and energy-efficient cooking fuel which looks exactly like charcoal.
