Kenya disposes of an estimated 4.5 million end-of-life tyres annually, with the vast majority dumped in informal sites or burned in the open, yet pyrolysis technology can convert each tonne of waste tyres into approximately 400 litres of fuel oil, 350 kilograms of carbon black, 120 kilograms of steel wire, and combustible syngas. Investors assume the technology risk is the barrier, but the actual bottleneck is feedstock aggregation logistics and output market price volatility that operators like Dennis Njoroge cannot track with manual systems. AskBiz provides pyrolysis operators with real-time yield tracking, input-output cost analytics, and feedstock supply monitoring while giving investors aggregated plant performance data across Kenya's emerging waste tyre processing sector.

The Conventional Wisdom Says Tyre Recycling Cannot Work in Kenya — Dennis Disagrees#
Ask ten waste management consultants in Nairobi whether pyrolysis is a viable business for processing end-of-life tyres in Kenya and at least seven will tell you the same thing: the technology is proven in theory but uneconomic in practice for East African conditions. They will cite high capital costs for reactor equipment, unreliable electricity supply, the absence of quality standards for pyrolysis fuel oil, and a feedstock supply chain that is too fragmented to deliver consistent volumes. Dennis Njoroge has heard every one of these objections, and he disagrees with all of them — not from a theoretical position but from the evidence of his own profit-and-loss statement. Dennis operates a batch pyrolysis plant on a half-acre industrial plot in Thika, approximately 40 kilometres northeast of Nairobi along the Thika Superhighway. His reactor, a 10-tonne batch unit manufactured in Henan Province, China, and installed in mid-2023 at a total landed cost of KES 12.8 million, processes end-of-life tyres through thermal decomposition in an oxygen-free environment at temperatures between 400 and 500 degrees Celsius. The process breaks down tyre rubber into four saleable outputs: pyrolysis fuel oil, carbon black, steel wire, and non-condensable syngas that Dennis uses to heat the reactor, reducing his diesel consumption. In 2025, Dennis processed approximately 1,800 tonnes of waste tyres and generated gross revenue of KES 28.4 million against operating costs of KES 17.6 million, yielding a pre-tax margin of approximately 38%. These are not projected numbers from a feasibility study — they are actual results from a plant that runs six batch cycles per week, forty-eight weeks per year. The consultants who say pyrolysis does not work in Kenya are not wrong about the challenges. They are wrong about the conclusion.
Input Economics: Where Dennis Finds 150 Tonnes of Waste Tyres Per Month#
The feedstock question is where most pyrolysis business plans go wrong, and where Dennis has built a competitive advantage through relationship-based supply chain management that no competitor has yet replicated in the Thika corridor. Kenya's National Environment Management Authority estimates that the country generates approximately 4.5 million end-of-life tyres annually from passenger vehicles, trucks, buses, motorcycles, and agricultural equipment. The largest concentrations are in Nairobi, Mombasa, Nakuru, and Kisumu, with significant volumes along the Northern Corridor transport route that connects Mombasa port to Uganda, Rwanda, and the Democratic Republic of Congo. Despite these volumes, aggregating waste tyres at a pyrolysis plant is not as simple as placing a collection bin and waiting. Dennis sources tyres from three channels. The first is a network of twenty-two tyre dealers and mechanics workshops in Thika, Ruiru, Juja, and Nairobi's Industrial Area who set aside their used tyres for Dennis in exchange for a collection service and a modest payment of KES 5 to KES 15 per tyre depending on size. Passenger car tyres weigh approximately 7 to 9 kilograms each, while truck tyres range from 40 to 80 kilograms. The second channel is two fleet operators — a matatu SACCO with 45 vehicles and a logistics company with 28 trucks — who provide end-of-life tyres in bulk at scheduled intervals. The third is opportunistic purchases from the informal tyre collectors who scavenge dumps and roadsides, selling at KES 8 to KES 20 per tyre. Across these channels, Dennis aggregates approximately 150 tonnes of waste tyres per month at a blended feedstock cost of approximately KES 3,200 per tonne. This cost has increased from roughly KES 2,400 per tonne in 2024 as competition from a second pyrolysis entrant in Athi River has bid up prices from some of Dennis's supplier relationships.
Output Yields and Revenue: The Four-Product Model#
Pyrolysis is fundamentally a manufacturing process, and like any manufacturing process, its economics depend on yield rates and output pricing. Dennis's 10-tonne batch reactor produces consistent yields per tonne of input tyres: approximately 400 litres of pyrolysis fuel oil, 350 kilograms of carbon black, 120 kilograms of steel wire, and the balance as non-condensable gas and minor residual ash. These yields align closely with the technical specifications published by the reactor manufacturer and with performance data from comparable batch pyrolysis operations documented in UNIDO case studies across Southeast Asia and North Africa. Pyrolysis fuel oil is Dennis's primary revenue driver, accounting for approximately 55% of gross revenue. The oil has a calorific value of roughly 38 to 42 megajoules per kilogram, making it suitable as an industrial heating fuel for brick kilns, cement plants, and steel foundries. Dennis sells to three industrial buyers in Thika and Nairobi's Industrial Area at prices ranging from KES 65 to KES 80 per litre, depending on the buyer and current diesel prices, which serve as the informal benchmark. At an average realised price of KES 72 per litre and 400 litres per tonne of input, fuel oil revenue is approximately KES 28,800 per tonne of tyres processed. Carbon black is the second product, sold to rubber compounders and paint manufacturers at KES 18 to KES 25 per kilogram. Dennis currently sells unrefined carbon black at the lower end of this range — KES 18 to KES 20 per kilogram — because he lacks the milling and pelletising equipment to upgrade the product to the N660 or N774 grades that command premium prices. At 350 kilograms per tonne of input and KES 19 per kilogram average, carbon black contributes approximately KES 6,650 per tonne. Steel wire, extracted magnetically after the pyrolysis cycle, sells to Nairobi scrap dealers at KES 35 to KES 42 per kilogram, contributing roughly KES 4,500 per input tonne. Total blended revenue per tonne of tyres processed is approximately KES 39,950, against a feedstock cost of KES 3,200 and per-tonne processing costs that Dennis estimates at KES 8,800, yielding a gross margin per tonne of roughly KES 27,950.

The Risks Investors Must Price: Volatility, Regulation, and Scale#
Dennis's 38% pre-tax margin is real but not guaranteed, and investors considering the Kenyan tyre pyrolysis sector need to understand the risk factors that could compress or eliminate it. The first is output price volatility. Pyrolysis fuel oil competes with diesel and heavy fuel oil in the industrial heating market, and its price tracks crude oil movements with a lag. When global oil prices dropped 18% in Q3 2025 during a demand slowdown, Dennis's fuel oil buyers pushed back on pricing, and his average realised price fell from KES 78 to KES 65 per litre for two months before recovering. A sustained oil price decline would compress the fuel oil margin that provides the majority of his revenue, and Dennis has no hedging instruments available to manage this exposure. The second risk is regulatory uncertainty. NEMA has issued environmental impact assessment approvals for existing pyrolysis operations, but the regulatory framework for pyrolysis fuel oil quality standards and emissions limits from pyrolysis plants is still developing. Dennis's plant was inspected by NEMA in 2025 and received a clean compliance report, but he is aware that stricter emissions requirements could mandate scrubber or filter equipment upgrades costing KES 3 million to KES 5 million. The third risk is the challenge of scaling beyond batch processing. Dennis's reactor processes 10 tonnes per batch cycle over a 10 to 12 hour period, limiting throughput to roughly 60 tonnes per week under optimal conditions. Moving to continuous pyrolysis reactors that process 30 to 50 tonnes per day would require capital investment of KES 45 million to KES 70 million and a level of feedstock supply reliability that the current informal collection network cannot guarantee. Feedstock competition is already a live concern: the Athi River entrant has bid up tyre prices in some supply corridors by 25% to 35%, and if additional operators enter the market, feedstock costs could rise faster than output prices, squeezing margins across the sector.
How AskBiz Tracks Pyrolysis Plant Performance for Operators and Investors#
AskBiz addresses the data requirements of the tyre pyrolysis sector by providing operators like Dennis with integrated tracking across the entire input-output cycle. The feedstock module logs every tyre delivery by source, quantity, tyre type, weight, and cost, creating a supply chain database that reveals which channels deliver the most volume at the lowest cost and which supplier relationships are at risk of disruption from competitor poaching. Over time, this data enables Dennis to forecast feedstock availability and cost with increasing accuracy, reducing the planning uncertainty that currently forces him to maintain a four-week tyre stockpile as a buffer against supply gaps. The production module records each batch cycle's input weight, processing duration, fuel oil yield in litres, carbon black yield in kilograms, and steel wire recovery weight. Yield rates per batch are tracked against the reactor's rated specifications, and deviations trigger alerts that help Dennis identify maintenance needs before they cause unplanned shutdowns. The revenue module tracks each output sale by product, buyer, quantity, and price, calculating per-batch and per-tonne profitability in real time rather than at month-end. For investors, AskBiz aggregates anonymised plant performance data from pyrolysis operators on the platform, producing the sector benchmarks that do not currently exist in the Kenyan market: median yield rates by reactor type, feedstock cost trends by region, output price realisation by product and buyer category, and margin distributions across operators at different scales. This data layer transforms pyrolysis from an opaque manufacturing bet into an underwritable industrial investment with verifiable performance metrics.
The Tyre Waste Opportunity Is Real — Enter It with Data#
Kenya's end-of-life tyre problem is large enough and persistent enough to support a profitable pyrolysis processing sector, provided operators manage feedstock costs, maintain yield discipline, and adapt to output price fluctuations with the agility that only real-time data enables. If you are an investor evaluating the tyre-to-fuel value chain in Kenya, the unit economics are demonstrably attractive at current output prices, but the risks — oil price correlation, regulatory evolution, feedstock competition — require the kind of ongoing operational data that Dennis and his peers are not yet equipped to provide through manual tracking. AskBiz bridges this gap, delivering verified plant performance data that allows you to underwrite pyrolysis investments with confidence, benchmark portfolio companies against sector medians, and monitor operational health between board meetings. Request an investor analytics demo and see how tyre pyrolysis plant data translates into actionable intelligence for circular economy investment in East Africa. If you are an operator running or planning a pyrolysis plant in Thika, Athi River, Nakuru, Mombasa, or elsewhere in Kenya, AskBiz gives you the production tracking and financial analytics to maximise yield, optimise feedstock sourcing, and present your business to investors and lenders as a data-driven industrial operation. The difference between a pyrolysis plant that attracts growth capital and one that remains a small-batch operation is not the reactor — it is the data infrastructure behind it.
