Fifteen African entrepreneurs, including three Nigerians, and their pioneering technologies aimed at environmental rehabilitation, education, and human health and safety have been shortlisted for the 2023 Africa Prize for Engineering Innovation, founded by the Royal Academy of Engineering.

The 2023 shortlist represents ten African countries, including for the first time Angola and Sierra Leone, and demonstrates the importance of engineering as an enabler of improved quality of life and economic development, a statement from the organisers said.

The innovations shortlisted in 2023 tackle challenges central to the UN’s Sustainable Development Goals, including quality education, clean water and sanitation, sustainable cities and communities, good health and wellbeing, and clean energy. This year’s innovations include a treatment to convert acid mine drainage into drinking water, a portable aquaponics unit that uses fish waste to boost production of vegetables, a robotics learning tool for children, a remote healthcare monitoring system, and an ecofriendly cooking stove that absorbs black carbon.

Launched in 2014, the Africa Prize is awarded annually by the Royal Academy of Engineering to ambitious African innovators creating local and scalable solutions to pan-African and international challenges. Innovators shortlisted for the Africa Prize will benefit from a unique package of support including business incubation, mentoring, fundraising and communications. The package also includes access to the Academy’s global network of high-profile and highly experienced engineers and business experts in the UK and Africa.

In mid-2023 four finalists will be chosen to pitch their innovations and business plans to Africa Prize judges at an event in Accra, Ghana. The winner will receive £25,000, and three runners up will win £10,000 each. An additional One-to-Watch award of £5,000 will be given to the most promising innovator.

This year’s shortlisted innovators join the Academy’s 134-strong Africa Prize alumni network, which includes innovators who have achieved significant commercial success and social impact across the continent following their participation in the Prize, such as 2022 winner Norah Magero, and her portable solar-powered fridge solution for transporting medicines.

Africa Prize alumni are projected to have an impact on more than three million people in the next five years, and have already created 3,585 jobs – including 1,766 for women and 211 for persons with disabilities – and raised more the USD 14 million in grants and equity funding, directly contributing to 12 of the UN Sustainable Development Goals.

The 2023 shortlist features several water innovations, including a real-time water quality monitoring and control system, an acid mine drainage solution to recycle contaminated water for human consumption, and a water management system to prevent excess borehole pumping and drying out of aquifers.

Energy and environmental solutions also feature heavily, with a power pack with recycled laptop batteries to address unreliable power supply, converted motorbikes that run on batteries, an electric cargo bike with a battery-powered fridge to reduce post-harvest loss, a system to help prepare waste for recycling, a mobile machine to create interlocking compressed earth bricks, and an ecofriendly cooking stove that absorbs black carbon.

Additionally, several entrepreneurs shortlisted have pioneered solutions in health, safety and education, with a portable hysteroscopy device for simple examination of the uterus, a remote healthcare monitoring system that records and transmits patient data, a multi-strain probiotic to improve the gut health of chickens, a local rescue network connecting neighbours with the police, and a robotics learning tool for children.

Rebecca Enonchong FREng, founder and CEO of AppsTech and Africa Prize judge, said, “Climate change is impacting Africa more severely than other continents, with agricultural production, food security and water resources being compromised, compounded by a weak adaptive capacity. This year, 11 of our innovations are contributing directly to environmental sustainability.”

Shortlisted innovations and entrepreneurs:

Affordable AMD Solution, Boitumelo Nkatlo, South Africa – A technology to treat acid mine drainage (AMD) using industrial waste to recycle contaminated water for human consumption.

Aquaset, Obed Zar, Ghana – A smart water management system that monitors water levels in boreholes and water tanks, regulating the rate at which water is pumped and preventing pump breakdowns and water waste.
