When Fertilizer Becomes a Shipping-Lane Problem: Why Kenya's Waste Streams Are a Financing Opportunity, Not Just an Environmental One

Since the closure of the Strait of Hormuz earlier this year — a route carrying roughly a quarter of global ammonia trade and more than a third of seaborne urea — the World Bank’s fertilizer price index has been on its steepest annual climb since 2022, now projected to rise more than 30 percent in 2026 (World Bank Group, Commodity Markets Outlook, May 2026). Rerouted freight, higher insurance premiums on Gulf-linked cargo, and suspended output at Iranian and Qatari plants have all fed into landed costs across East Africa (World Bank Group, May 2026).

Kenya is directly exposed: roughly 38 percent of its fertilizer supply is sourced from Gulf markets, and the country imports effectively all of its fertilizer (Forbes Africa, citing FAO data, May 2026) — a dependence shared by other East African importers. The transmission to farmers is already visible on the ground: in Trans-Nzoia, a principal maize-growing county, farmers queued at government depots this spring as commercial fertilizer prices climbed well beyond subsidised rates (Mongabay, 3 July 2026). That subsidy reliance is itself a signal of fragility, when global prices spike, farmers without subsidised access are the most exposed, and government programmes face growing fiscal pressure to keep pace with demand.

The shock has compounded with a second, related one. Diesel prices in Kenya rose from KSh165.63 per litre in February 2026 to a peak of KSh242.92 in mid-May — a 47 percent increase in three months — before a partial regulatory correction brought it to KSh232.86 (EPRA data, via Mongabay, 3 July 2026). Because diesel underpins irrigation, input transport and mechanised land preparation, farmers report that fuel costs are now absorbing the savings gained from subsidised fertilizer before a crop is even planted (Mongabay, 3 July 2026).

A Structural Vulnerability, not a one-off

This is not a Kenya-specific event. It reflects a structural exposure shared across Sub-Saharan importing economies: near-total reliance on imported synthetic fertilizer, financing agriculture at the mercy of freight routes and geopolitics beyond their control. With 63 percent of Kenya’s arable land already acidic and 40 percent of its land degraded (Heinrich Böll Foundation, Soil Atlas 2025, via Mongabay), the region enters each shipping-lane disruption from a weakened soil-health baseline — compounding the food security risk rather than merely adding a cost line.

Waste Management and Animal Feed

Kenya’s other structural challenge, an estimated 1.4 million tonnes of CO2-equivalent emissions a year from unmanaged organic waste sits on the same balance sheet as its fertilizer dependence. Waste-derived organic fertilizer and insect-based animal feed offer a domestically produced alternative to both imported synthetic fertilizer and resource-intensive soy- and fishmeal-based feed, directly addressing two import-exposed inputs with one processing model.

Technical Assistance and Adjusted Risk Profile

SCF has deployed technical assistance to Biobuu, an East African Black Soldier Fly (BSF) company converting organic waste into protein feed and organic fertilizer across Kenya and Tanzania. TA support has targeted the specific uncertainties standing between a promising operation and a financeable one: a market study for BSF chitin and oil,  feasibility assessments across three new East African sites, a companion-animal product line, an independently commissioned fertilizer trial (agronomic validation), and on-site research to raise larval breeding and feeding rates (unit-cost improvement). The fertilizer trial is most relevant to the current crisis: in potato trials, BSF fertilizer combined with just half the standard synthetic rate matched 96.8 percent of full-synthetic yield, an early, independently verified indication that a domestically produced input can partially displace fertilizer exposed to Gulf shipping risk.

This is technical assistance functioning as SCF intends it: not funding an outcome, but closing the specific technical, market and process gaps that stand between a promising idea and a bankable one. Collectively, this work has moved Biobuu from an unvalidated concept toward a business with reduced revenue-concentration risk, de-risked expansion sites, and independently evidenced agronomic performance, the risk-adjusted profile investors and financiers require before committing capital.

Latest Milestone and Catalytic Capital Mobilized

Biobuu now reports having diverted approximately 45,000 tonnes of organic waste from landfill, a 67 percent emissions reduction relative to landfill disposal, 50 local jobs, and roughly 350 farms using its organic fertilizer.

This operational base has already attracted capital beyond SCF’s TA facility including Catalyst Fund investment in Biobuu’s expansion, and the company previously secured $200,000 in seed funding from the GIIG Africa Fund alongside an EU export licence. These are the proof points SCF’s model is designed to produce — evidence that targeted technical assistance, not grant funding alone, is what moves a subnational climate infrastructure project from concept to a financeable, capital-ready proposition.

About the Subnational Climate Fund

The Subnational Climate Fund is a blended-finance initiative supporting mid-sized infrastructure projects and companies in emerging markets. Through its Investment Fund and Technical Assistance Facility, SCF strengthens project fundamentals, enhances investment readiness and mobilises private capital for sustainable development outcomes across sectors including sustainable energy, waste management and regenerative agriculture. By focusing on early-stage project preparation, SCF bridges ambitious climate and nature objectives with the requirements of institutional investors, development finance institutions and philanthropic capital providers.
