Dr Askwar Hilonga and team, Tanzania, WINNER
The Nanofilter integrates cutting-edge nanotechnology with sand-based water filtration to provide clean, safe drinking water. The process is affordable and sustainable and highly relevant in rural settings across Africa where access to clean water remains a huge challenge. Custom built per region, it gives communities access to existing bodies of water that were previously too polluted to use.
Samuel Njugana Wangui, Kenya, FINALIST
In Kenya, most mobile phone users have at least two SIM cards to ensure signal strength across different carriers. Chura is a web-based multi-network system which allows users to move airtime between their different SIMs regardless of carrier, buy airtime from service providers that can be used on any network, send airtime to family members or employees, or exchange airtime for cash.
Ernst Pretorius, South Africa, FINALIST
Mounted to the wiring posts of a fence, the Draadsitter (Afrikaans for ‘fence sitter’) is a fence security alarm system. The innovation detects tampering on fences of up to 800 metres, and can also detect fires. Using sensors, the device warns owners of the location and nature of tampering on their fence, allowing them to react before security is breached.
On-Spot Fertilizer Applicator
Musenga Silwawa, Zambia, FINALIST
Small-scale farmers in Zambia typically apply commercial fertiliser to their crops by hand, which not only results in inconsistent application but is labour intensive and time consuming. Designed to mimic a walking stick, the On-Spot Fertiliser Applicator is an efficient and consistent device that allows farmers to apply fertiliser directly to their crops with one simple action. It is light and affordable and eliminates wastage, making it environmentally friendly.
Clear Banana Juice
Dr Oscar Kibazohi, Tanzania
Clear banana juice is difficult to produce because pulping ripe bananas produces a highly viscous puree. This innovation mashes bananas mechanically without the addition of enzymes or extraction aids to create clear banana juice. It mirrors the traditional process of kneading a mixture of ripe banana and grass or fibres until the juice oozes out from the pulp. This makes juice-producing banana varieties, which fetch low prices and are being phased out, into a more valuable product.
FlexiPay / The Engineering Lab
Ayo Adigun and team, Nigeria
Mr Adigun was shortlisted for FlexiPay, a mobile money solution that allows merchants and customers to make and receive payments using their phones and tablets.
Switching focus, today, he is a part of The Engineering Lab (E-Lab) team. The E-Lab is a educational outfit working to build the technical and scientific capacity of young people through Science, Technology, Engineering, Art and Mathematics (STEAM). Aiming to turn young brilliant minds into future engineers, scientists and innovators. Based in Nairobi, Kenya the E-Lab works with educational institutions to integrate STEAM alongside their mainstream curriculum. These are delivered weekly through an after school programme or as a timetabled lesson. Since 2015, over 350 students have enrolled in the E-Lab program.
Dr Reinhardt Kotzé, South Africa
Flow-Viz is an innovation which improves process and quality control in fluid industrial operations. It replaces time-consuming off-line measurements in the quality control laboratory with continuous real-time process monitoring taking place directly in the production line. Flow-Viz includes a sensor unit, operator’s panel and software to analyse viscosity and flow-profiles. Pilot tests have been conducted on products such as cement grout, yoghurt, soup, bio-chemicals like ethanol and paper pulp.
Macjames Chemical Products
Justin Nwaogwugwu and team, Nigeria
Macjames MMDC-11 is an affordable, heavy-duty multi-purpose cleaner that removes organic and inorganic dirt from washable surfaces. Produced using biodegradable raw materials, it is environmentally-friendly, non-corrosive and non-acidic. It cleans an array of materials and is particularly suited to manufacturing, mining, and agricultural applications.
Ian Mutamiri and team, Zimbabwe
This Android application from Zimbabwe teaches children how to read Shona by improving their syllable-to-sound association. The innovation is specially geared for children with reading difficulties, and focuses on teaching children languages using native speakers whose accent and intonation they recognise. The application could also be used to teach other languages.
Portable Gold Crusher
Rujeko Masike, Zimbabwe
The small to medium mining sector in Zimbabwe has a need for portable ore crushing machines. This innovation scales down regular machinery and incorporates local materials to make affordable, portable, sustainable and appropriate crushing machines for local miners.
Removable Burglar Bar
Major Abubakar Imam, Nigeria
A Major in the Nigerian army, Imam has created a removable burglar-bar system that enables a quick emergency exit from a building, enhancing safety without sacrificing security. A locking mechanism incorporated within the burglar-bar system can only be opened from the inside. Until unlocked, the bars are impenetrable. Users can feel safe and secure in their home or business, without the burglar bars preventing their escape in an emergency.

People living in Kampala rely heavily on traditional pit latrines in the absence of flushing toilets. Latrines are easily flooded, increasing the risk of diarrheal disease. Sanitation Africa represents a series of innovative sanitation technologies focussed to improve urban sanitation. Appropriate technologies are used to improve pit latrines, to provide an efficient emptying service, to transport and treat faecal sludge and to re-use treated sludge.
