How one Kenyan county learned to stop wasting fruit—and start making money
Compiled by Ethical Business Africa
When the mango season ripens across Kenya’s Makueni County, what once rotted by the roadside is now driving a circular agribusiness revolution. A new county-run aggregation and processing hub is giving farmer cooperatives the tools to turn “green gold” into jobs, exports, and zero waste.
What happened
In January 2025, Makueni County launched a Horticultural Aggregation Centre and Packhouse in Wote to strengthen its mango export chain and curb post-harvest losses. The facility, located near the Wote Police Station, will serve as a central collection, grading, and packaging point for both export and domestic fruit.
According to official data, export-grade mangoes from the centre fetch KSh 12 per piece, while fruit destined for local markets earns between KSh 15 and KSh 19 per kilogramme. County officials say the facility is already easing long-standing logistical bottlenecks that led to waste levels exceeding 40 % in past seasons.
“This is more than a market access project — it’s about value, dignity, and sustainability for farmers,” Governor Mutula Kilonzo Jr. said during the launch.
Why it matters
Makueni is Kenya’s largest mango-producing county, home to over 4 million mango trees cultivated by about 28,000 farmers. In 2023, these farmers produced 199,626 metric tonnes of fruit worth roughly KSh 4.28 billion, according to county data. Yet nearly half of that output once went to waste due to poor handling and limited cold-chain capacity.
Globally, food loss and waste cost Africa over US$40 billion a year, according to the FAO. Reducing that waste is central to the circular-economy agenda — and Makueni’s strategy is proving that it can be done locally, through cooperative innovation and public investment.
Who’s affected
For farmers like Mary Mueni, chair of the Kathonzweni Mango Cooperative, the new system is rewriting household economics. “Before, we sold fruit at throw-away prices or watched it spoil. Now, we grade, sort, and even sell by-products. Nothing is wasted,” she said in an interview.
More than 70,000 households in the county depend on mango farming. During the last export season alone, Makueni shipped 4,907 tonnes of mangoes, worth over KSh 300 million (US$ 2.3 million), to markets including the UAE and the UK.
By linking smallholders directly to export-ready processing, the county hopes to more than double earnings in the next two seasons.
How it plays out
At the new centre, co-ops aggregate fruit from surrounding wards. Export-grade mangoes are sorted and packed, while lower-grade produce is channelled into pulp and dried-fruit processing. The Makueni County Fruit Development and Marketing Authority coordinates the logistics, while private processors and exporters handle outbound shipments.
Meanwhile, by-products like peels and kernels are being trialled as livestock feed and organic compost — early steps toward a full circular model.
The county has also designated eight Areas of Low Pest Prevalence (ALPP) to reduce fruit-fly damage and improve phytosanitary compliance for export markets.
The bigger picture
The aggregation-hub model fits into Kenya’s broader bio-economy ambition. The government, in partnership with TradeMark Africa, plans to establish an Export Supply Hub integrating cold storage, traceability, and logistics for multiple horticultural crops.
Analysts say this infrastructure push positions Makueni as a testing ground for Africa’s circular-agriculture investment. “If the model works here — where climate risks and infrastructure gaps are toughest — it could scale across the region,” said David Njenga, an agribusiness consultant based in Nairobi.
The transition aligns with global trends in sustainable supply chains, where waste valorisation and farmer-led processing are attracting impact-finance capital from the IFC, AfDB, and green-banking funds targeting smallholder-linked enterprises.
The takeaway
Makueni’s mango co-ops demonstrate that circular agribusiness can thrive when public infrastructure meets private initiative. The county has shifted from being Kenya’s symbol of fruit waste to a case study in value retention.
As Governor Kilonzo put it:
“Our farmers no longer measure success by harvest alone — but by how much value they keep from every mango.”

Investor map — 5 finance routes for co-ops in Kenya
1) Novastar Ventures — growth-stage impact capital (equity / growth debt)
What it is: Pan-African impact investor focused on early-to-growth companies that scale services, agri-value chains and climate adaptation solutions. Novastar runs Africa-focused funds and recently raised new LP commitments for a climate-oriented vehicle.
Typical ticket / instrument: Equity or structured growth capital. Typical checks vary by fund but are sized for scaling companies (US$1M–$20M+ depending on the round).
Why it fits: Novastar backs business models that combine inclusive supply-chain aggregation and unit economics — precisely the characteristics of co-op-driven processing that can show margin from pulp, by-products and energy.
How co-ops should approach:
• Consolidate audited financials and a 3-year growth plan showing unit economics for pulp vs by-products.
• Prepare a clear governance story that demonstrates professional management alongside cooperative ownership (investors worry about governance risk).
• Target Novastar for growth equity once you demonstrate repeatable revenues and export or scale pipeline.

2) KCB Group — green/climate loans & sustainability-linked facilities
What it is: Kenya’s largest bank, accredited by the Green Climate Fund (GCF) to finance climate mitigation/adaptation projects; KCB has stepped up green lending and sustainability-linked facilities.
Typical ticket / instrument: Green loans, asset finance, and sustainability-linked loans. KCB’s accreditation allows project financing in the US$50M–250M range from GCF lines, while local green loans can be smaller and bank-tailored for SMEs.
Why it fits: KCB can underwrite cold-storage, biogas units, and processing equipment as green assets, and may offer preferential pricing where projects deliver measurable emission reductions or climate resilience
How co-ops should approach:
• Package capital expenditure (cold rooms, dryers, biogas digesters) as “green assets” with emissions and job metrics.
• Request a blended package: KCB debt + grant or concessional DFI guarantee to reduce collateral needs.
• Use KCB’s sustainability loan checklists to fast-track approval.

3) Co-operative Bank of Kenya — cooperative & agri-value chain lending (warehouse & pre-harvest finance)
What it is: Major domestic bank with explicit agri-business products for cooperatives: pre-harvest finance, supply-chain finance and lending for processing plants; the bank documents cooperative lending models in feasibility studies.
Typical ticket / instrument: Short-term working capital, pre-harvest loans, and asset finance; deals range from modest KSh-level working capital to multi-million shilling facility for plant upgrades. Co-ops often borrow as the primary obligor with members as guarantors.
Why it fits: Co-ops with strong aggregation and repayment history can access working capital tied to inventory (warehouse-receipt style) and pre-harvest finance to smooth seasonality. The Co-op Bank already designs products for horticulture/flower/value-chain players.
How co-ops should approach:
• Formalise aggregation agreements and introduce warehouse receipts or signed off-take contracts to serve as collateral.
• Start with short-term working capital (inputs, collection logistics) and build repayment track record before applying for capex loans.
• Use the bank’s ESG/ESG reporting to demonstrate social impact and creditworthiness.

4) Stawisha (Stawisha SME Mashinani) — government revolving fund & MSME support
What it is: A government-backed revolving fund launched to unlock credit for grassroots SMEs (originally announced at ~KSh 4 billion). The programme is implemented via designated agencies that provide guarantees, grants or credit lines to MSMEs at the county level.
Typical ticket / instrument: Small to medium tickets (micro-grants, concessional loans, or guarantee support) targeted at MSMEs and cooperatives; designed for entry-level finance rather than large capex.
Why it fits: Stawisha’s mandate is exactly to bridge the “missing middle” for grassroots value-add activities, making it a natural match for co-op projects that need smaller, lower-cost capital for equipment or working capital.
How co-ops should approach:
• Apply through the county’s nominated implementing agencies (MSEA, IDB Capital, KNBC or other designated programme partners).
• Package projects as job-creating, value-addition activities with clear cost-per-job and income uplift metrics.
• Seek blended support: Stawisha funding + bank debt for leverage.

5) Boost Africa / EIB-AfDB blended instruments — blended finance & catalytic guarantees
What it is: An EU-backed initiative (EIB + AfDB) that provides blended finance, guarantees and capacity building for African agribusiness, fintech and SME scaling; it targets sectors including agribusiness and value chains, often mobilising follow-on private capital.
Typical ticket / instrument: Blended facilities, partial credit guarantees, technical assistance and risk-sharing instruments that make banks and funds comfortable financing smaller agribusiness projects. Ticket sizes vary; the instrument’s role is often catalytic rather than direct long-term finance.
Why it fits: Boost Africa’s blended approach can reduce perceived risk for lenders financing co-op processing plants or cold chains, enabling larger bank loans or fund investments to flow.
How co-ops should approach:
• Engage county government to request that projects be included in blended finance calls or investment briefs to Boost Africa/EIB/AfDB teams.
• Seek technical assistance grants first (feasibility + bankable project preparation) from Boost Africa windows before applying for debt.
• If awarded partial guarantees or TA, use these to negotiate better terms with local banks (e.g., KCB, Co-op Bank).

Practical prioritisation for co-ops (three-step plan)
- Short term (0–6 months): Apply to Stawisha channels and Co-operative Bank for working capital and warehouse/pre-harvest finance; build repayment track record and formal off-take contracts.
- Medium term (6–18 months): Use KCB green-loan routes for biogas and cold-chain assets; pair with county data on emission reductions to access preferential pricing.
- When revenue scale is proven (18+ months): Package a growth-equity ask to impact funds (e.g., Novastar) or seek blended finance windows via Boost Africa / EIB to de-risk larger private investment.
Final notes on documentation & deal readiness
Lenders and investors want a compact “investment pack”:
• 12–24 months of bank statements and at least one audited year (or certified accountant review).
• Aggregation agreements with member lists, volumes and delivered quality metrics.
• Off-take letters or commercial contracts (local buyers, processors, exporters).
• Environmental & social metrics: waste reduction, jobs created, emissions avoided.
• Governance charter showing co-op structure and management team.
