What BioMassters does
BioMassters Ltd. is a Rwandan clean-cooking company founded in April 2020 and headquartered in Kigali, with operations spanning 5 retail shop locations across the city (Gisimenti, Gikondo, Kimironko, Nyamirambo, Kimisagara). The company produces 'Made in Rwanda' biomass pellet fuel from wood waste and agricultural residues, positioning itself as Rwanda's largest pellet producer, and complements the fuel business with two locally designed and assembled Tier-4 gasification stoves — the fixed Iryacu and the portable InzuChef. Its technology stack is mechanical-industrial: pellet manufacturing from biomass waste plus advanced biomass gasification stove engineering, with an explicit circular-economy feedstock model drawing on forest management, reforestation, and furniture production residue streams.
The company serves three primary segments: low-income Rwandan households replacing charcoal and LPG (the primary segment), schools and educational institutions via pellet-burner kitchen retrofits (83% fuel savings, PM2.5 compliance), and modern households seeking portable, design-forward pellet cooking via InzuChef. Revenue is a hybrid of recurring pellet fuel sales (usage-based, pay-as-you-go) and one-time stove sales (Iryacu and InzuChef), distributed through physical retail shops, a website request-quote channel, and direct enterprise engagement for school retrofits. Go-to-market blends community-led outreach (Umuganda awareness campaigns, NGO partnerships, school retrofit channels) with direct-to-consumer retail.
BioMassters is led by co-founders Claudia Muench (CEO) and Innocent Nsekeyukunze (Chief Production Officer), with COO Yasmine Karam and Director of Business Development Sylvain Rucyaha (ex-Bralirwa/Heineken). The board includes Chair Claude Mansell and Acumen representative Wanji Ng'ang'a, alongside Dr. Christian Rakos (President, World Bioenergy Association) and Charity Kagenza. Acumen is the company's largest funder, with additional institutional support from Innovate UK, EEP, LuxAid, Osprey, CCA, EDCL, and the Rwanda Ministry of Local Government. The company received the SET Award 2026 (Quality Energy Access & SDG-7) from dena, selected from over 470 applications across 79 countries.

BioMassters product offering
Product offeringCore offering
BioMassters manufactures and sells biomass pellet fuel produced from wood waste and agricultural residues, paired with Tier-4 gasification pellet stoves (Iryacu and InzuChef). Its integrated stove-and-fuel system is sold to Rwandan households and schools as an affordable, smoke-free alternative to charcoal, firewood, and LPG.
Product overview
BioMassters offers a clean cooking solution comprising two main product lines: pellet fuel (produced from biomass waste materials) and pellet stoves. The pellet product is Rwanda's largest pellet production operation, while the company manufactures two distinct stove models—the Iryacu (a fixed, brick-constructed Tier-4 gasifier stove) and the InzuChef (a portable, mobile pellet stove)—both designed to use the company's pellet fuel as an alternative to charcoal and LPG.
