Wastage Management
- Africa’s Carbon Removal Pioneer Biochar Carbon Removal Africa Limited is a Kenyan climate-tech company headquartered in Nairobi with operations in Ngata, Nakuru. We transform agro-processing waste and sawdust — including rice husks, maize cobs, coffee husks, sugarcane bagasse, and timber mill sawdust — into high-quality biochar through certified carbonisation. Nothing goes to waste; everything cycles back. We are driven by two interconnected principles: regenerative agriculture and agri-circularity. Regenerative because our biochar actively rebuilds soil health, biodiversity, and water cycles that intensive farming has depleted. Circular because every tonne of waste we collect from agro-processors and sawmills is returned to farmland as a life-giving soil amendment — closing the loop between waste and renewal. Our mission is twofold: restore degraded African soils and permanently remove carbon dioxide from the atmosphere. By selling verified carbon credits alongside our biochar product, we create a dual revenue model that rewards partners financially while delivering measurable climate impact. We are actively seeking strategic partners — investors, agri-dealers, NGOs, and impact funds — who share our vision of a regenerative, carbon-negative Africa
- Our six Pillars:
- *Agri-Circular — Waste from agro-processors & sawmills becomes premium soil amendment; nothing leaves the system
- * Regenerative — Actively restoring soil biology, water cycles, and biodiversity depleted by intensive farming
- * Science-Backed — Biochar produced to IBI & EBC standards with rigorous quality testing at every batch
- * Investment-Ready — Dual revenue from biochar product sales & verified carbon credits with transparent financials
- * Local Impact — Smallholder farmer partnerships and waste-collection programmes across the Rift Valley
- * Scalable Model — Modular production units deployable across Sub-Saharan Africa wherever waste streams exist
Our Process - Regenerative Agri-Circularity in Practice We don’t just reduce waste — we close the loop entirely. Every step in our process feeds the next, creating a self-reinforcing cycle of agricultural renewal and carbon removal. Step 01: Waste Collection & Preparation We collect agro-processing waste — rice husks, maize cobs, coffee husks, sugarcane bagasse — and sawdust from timber mills across Nakuru and the surrounding regions. Feedstock is sorted, sun-dried, and sized for optimal carbonisation. This is material that would otherwise be openly burned or sent to landfill, generating greenhouse gas emissions with no productive value. Step 02: Certified Carbonisation (Pyrolysis) The prepared feedstock is loaded into our certified carbonizer — an industrial pyrolysis unit operating at 400–700°C in a controlled, low-oxygen environment. This thermal conversion process chemically transforms organic carbon into a highly stable, porous solid: biochar. The process also produces syngas, which is recovered and used as a heat energy source to power the next production cycle, making the process energy self-sufficient. What is Pyrolysis? Pyrolysis is the thermal decomposition of organic material at high temperatures in the absence of oxygen. Unlike combustion (burning), pyrolysis does not release the carbon as CO₂ — instead it locks it into a stable solid form that can persist in soil for hundreds to thousands of years. Step 03: Quality Testing & Certification Every batch of biochar undergoes laboratory testing for carbon content (>75% fixed carbon), pH (7.5–9.0), surface area (>300 m²/g), and contaminant screening. Results are recorded and linked to the batch serial number for full traceability. This data is also submitted to our carbon credit verification partner for issuance of certified carbon removal credits. Step 04: ZaoChar™ 50 Packaging Tested and certified biochar is milled to the optimal particle size for soil incorporation and packaged into 50 kg bags of ZaoChar™ 50. Each bag is clearly labelled with batch number, carbon content, production date, and application guidance. Our packaging is designed to withstand East African climate conditions during transport and storage. Step 05: Soil & Farm Renewal Farmers apply ZaoChar™ 50 to their fields at rates of 1–5 tonnes per hectare, incorporated into the topsoil at planting time or during land preparation. The biochar restores soil structure, colonises with beneficial microbes, improves water retention by 15–25%, and dramatically increases the efficiency of any fertiliser applied. The same land that produced the agricultural waste now directly benefits from it. Step 06: Carbon Locked. Cycle Complete. Carbon that would have re-entered the atmosphere through open burning or decomposition is now permanently sequestered in soil for 500+ years. Our carbon credit verification partner issues certified removal credits, which are sold to international corporations with net zero commitments. The revenue funds the next round of waste collection, production, and farmer outreach — the loop closes and the cycle begins again.
