Farm waste to factory grease: How a 24-year-old grease maker frames west Africa’s food industrialization

West Africa does not lose its food money only on the farm. It loses it after harvest. Crops rot. Raw nuts leave the coast. Finished products come back at a higher price. That was the practical argument in Kigali this week at the Africa Food Systems Forum.

The example that cut through the hall came from Ghana. Fareeda Mustapha is 24. She put her company, PureLube, in front of a presidential dialogue. The firm takes discarded cashew nut shells, the part most buyers ignore, and turns them into industrial grease for machinery. The model sits between the farm and the factory. It does not stop at raw cashew.

It sells a product factories and mechanics already import. The company says it is sourcing from about 3,000 smallholders and creating skilled jobs in production, not only field labour.

That is the hole Ghana and Côte d’Ivoire have lived with for years. They grow cashew. Too much of the nut still leaves unprocessed. Local industry then pays extra for imported oils and finished goods. A plant that turns farm waste into a manufacturing input is a small answer to a large pattern. The money is in the middle of the chain.

Nigeria is trying to make the same turn at a bigger scale. At the Council of the Wise session, former President Goodluck Jonathan went back to the e-wallet years. Digital subsidies proved government could reach smallholders. They did not, by themselves, make farming a business. That happens when someone will buy the crop, store it and process it.

Under President Bola Tinubu, the Federal Ministry of Agriculture and Food Security, led by Senator Abubakar Kyari, has put a heavier bet on that midstream. The Nigeria Postharvest Systems Transformation Programme, known as NiPHaST, is the flagship. Officials put yearly post-harvest losses at about ₦3.5 trillion. The programme is meant to cut that waste by building aggregation and processing clusters that young people and women can work in, and in some cases own.

The link between a Ghanaian grease start-up and a Nigerian grain corridor is the regional market. That is where AGRA is placing its effort. Less isolated farm projects. More help for governments to set rules, blend finance and align trade standards under the African Continental Free Trade Area and the ECOWAS corridor. The target is the unglamorous middle. Aggregators. Millers.

Processors. So outgrowers have a buyer all year, not only at harvest speeches.
Rwandan President Paul Kagame made the bank point at a youth town hall in Kigali. Commercial lenders will rarely fund early agrifood firms unless the state takes part of the risk. Ghana’s cashew to grease plants and Nigeria’s push to stop food rotting in the field are the same test. If policy and catalytic capital sit behind processing, agriculture is no longer only relief. It becomes industry.
