Food waste in Nigeria has various causes, including damage after harvesting and during transportation. Consumers are also to blame, since many buy larger amounts than they can consume. Shops can also do their share by reducing the amount of expired food thrown away, through computerised ordering systems and apps such as Chowberry.

In Nigeria a young green energy innovator has developed an electric mini-grid powered by biogas made from organic waste, and the power it’s generating, is benefitting 550 people of Rije village in Abuja.  Dubbed Waste2Watt, this first of its kind renewable energy project in the country, is generating 20 kilowatts of power, after converting agricultural and communal organic waste into electricity, by use of a biogas digester.  The electric power generated is then distributed via a mini-grid to the villagers.

Meet Africa's first playground lit by means of power generated from footfall kinetic energy. In other words, when players, runners or other people step on the tiles installed on the ground, electricity is generated and it is used to light up the field. It means that the more players hustle for the goals, the brighter the light shines inside the pitch.

In Cameroon, Nigeria and Sierra Leone, there is a growing number of entrepreneurs who are turning rubbish into innovation by making paving tiles and building materials from plastic waste. Pierre Kamsouloum, an entrepreneur from the Northern region of Cameroon was pioneering the technology. Pierre joined forces with Living Earth, an international NGO, and has travelled across Cameroon and to Nigeria and Sierra Leone to train others.
