Mamlo Foods is a women-centred social enterprise operating micro-factories in Teso, Kenya, that aggregates and processes peanuts into premium products (peanut butter, snacks and flour) while intentionally keeping value-addition and income inside farming communities. Mamlo’s pilot micro-factory model served roughly 400 women smallholders producing about 166 tonnes of peanuts annually, but chronic wet-season rains and prolonged open-sun drying exposed harvests to contamination and dangerous aflatoxin risk, created large post-harvest losses, and constrained throughput and market access. Synnefa partnered with Mamlo to design a commercial, climate-resilient post-harvest solution that aligned with Mamlo’s social mission and micro-factory business model. We supplied and commissioned a 120 m² smart solar dryer installed directly at the Mamlo micro-factory on a rent-to-own commercial plan, and integrated controlled drying protocols, hygiene measures and traceability workflows to meet food-safety requirements for premium markets. The implementation combined hardware (the dryer), process design (protocols for hygienic handling and staged drying), and commercial design (rent-to-own financing and operational handover) so Mamlo could scale without bearing prohibitive up-front capital costs. Deployment went beyond equipment: Synnefa led baseline diagnostics and pilot design, trained micro-factory operators and thousands of supplying farmers on best-practice drying, post-harvest handling and traceability, and supported Mamlo with stakeholder launches, market strategy and performance monitoring. Field training and quality controls enabled Mamlo to stabilize factory throughput and reliably accept larger volumes from farmers. Follow-on activities included baseline studies with academic partners to measure post-harvest loss and ongoing support to refine dryer siting and operational integration across multiple micro-factory sites. The results were transformative. The smart dryer cut drying time by roughly 50%, halved exposure to weather-related delays and materially reduced aflatoxin risk. Mamlo doubled the volume of peanuts it could collect and stabilize for processing, creating dependable off-take that encouraged farmers to increase production. Across Mamlo’s broader supply base (nearly 1,970 supplying farmers) reported outcomes included a 78% rise in farmer incomes, while product quality and market readiness improved significantly. Based on the pilot’s performance, Mamlo committed to expanding the dryer model to additional micro-factory sites (plans for eight more sites), demonstrating a clear pathway from technical pilot to commercial scale. The Mamlo partnership shows how appropriate hardware, practical process design and an inclusive commercial model (rent-to-own plus farmer and operator training) convert climate risk into reliable value for processors and profitable, safer markets for smallholder suppliers—especially women. For agribusinesses and funders, the project is proof that Synnefa can deliver turnkey, food-safety focused post-harvest systems that unlock volume, quality and income across smallholder value chains. Impact highlights: (1) 120 m² smart solar dryer installed on a rent-to-own plan. (2) ~50% reduction in drying time and large reduction in aflatoxin risk (3) Doubled peanut collection volumes and stabilized factory throughput (4) 78% average income increase across Mamlo’s 1,970 supplying farmers (5) Planned scale-up to 8 additional micro-factory sites
