hemical Engineer Noël N’guessan has won the Royal Academy of Engineering’s 2021 Africa Prize for Engineering Innovation with a biowaste equipment innovation for smallholder farmers in West Africa to efficiently manage and generate income from biowaste. N’guessan is the second Ivorian to win the Africa Prize, and the first to win with an Ivorian-based innovation.
N’guessan and his team designed and patented Kubeko to assist smallholder farmers and their cooperatives to generate more income from the by-products of their harvests, without any additional labour. Kubeko is a set of low-cost biowaste processing equipment; its composter and biodigester are both specifically designed to ferment agricultural post-harvest by-products into solid and liquid compost, and cooking gas.
“Biowaste represents two to five times the quantity of crops or produce sold, amounting to 30 million tonnes of waste disposed of annually in Côte d’Ivoire,” said N’guessan. “By repurposing this waste, Kubeko can help Ivorians generate extra income, dramatically improving the lives of thousands of farmers and their families.”
N’guessan wins the first prize of £25,000 (19 058 427,00 West African CFA). At the virtual awards ceremony held on 8 July 2021, four finalists delivered presentations, before Africa Prize judges and a live audience voted for the most promising engineering innovation.
“We really appreciated the professionalism of the APEI, adding value to our businesses. It was hard work, and share this Award with our entire team,” said N’guessan.
The Africa Prize for Engineering Innovation, founded by the UK’s Royal Academy of Engineering in 2014, is Africa’s biggest prize dedicated to engineering innovation, and has a proven track record of identifying successful engineering entrepreneurs. Now in its seventh year, it supports talented sub-Saharan African entrepreneurs with engineering innovations that address crucial problems in their communities in a new and appropriate way.
Since being shortlisted for the Africa Prize, the Kubeko team has made progress in reducing its production costs from US$800 to US$700, making their products affordable. The team has installed two biodigesters running on cassava farms, with 50 composters installed to date on cocoa, palm oil and mango farms. Kubeko has also been commissioned by the Ministry of the Environment and Sustainable Development in Côte d’Ivoire to train stakeholders on the use of Kubeko, as part of the department’s national composting and biowaste strategy.
“We were very impressed with the Kubeko solution which has huge potential to impact many lives of farmers in West Africa,” said Africa Prize Judge Ibilola Amao. “We believe Kubeko will contribute greatly to sustainable energy and farming in the region.
Sixteen shortlisted Africa Prize entrepreneurs from eight countries in sub-Saharan Africa received eight months of training and mentoring – conducted virtually due to the Covid-19 pandemic – during which they developed their business plans and learned to market their innovations. The group received coaching on communicating effectively, focusing on customers and approaching investors with confidence.
The Africa Prize also exposes and connects the shortlist to individuals and networks in the UK and across Africa who can accelerate their business and technology development – from fellow entrepreneurs and mentors to potential investors and suppliers.
