Q: What exactly is biochar and how is it made?
A: Biochar is a charcoal-like material produced by heating organic biomass in a low-oxygen environment through pyrolysis. At Biochar Carbon Removal Africa, we use a certified carbonizer operating at 400–700°C to convert agro-processing waste and sawdust into stable, high-grade biochar. Unlike regular charcoal, biochar is produced specifically for soil application and carbon sequestration.
Q: What feedstocks do you use to make ZaoChar™ 50?
A: We use 100% agro-processing waste and sawdust: rice husks from rice mills, maize cobs from cereal processors, coffee husks from wet mills, sugarcane bagasse from sugar factories, and sawdust and timber residues from sawmills and furniture workshops in the Nakuru region. No virgin biomass is used.
Q: How much biochar should I apply per hectare?
A: Recommended rates are 1–5 tonnes per hectare (20–100 bags of ZaoChar™ 50). For first-time applications on degraded soils, start with 2 t/ha and measure yield response. Biochar is a long-term investment — it does not need to be re-applied every season.
Q: Is biochar safe for all crops and soil types?
A: Yes. Biochar is chemically inert and non-toxic, safe for all crops and livestock. It is particularly effective on acidic, sandy, and highly weathered soils common across East and West Africa. ZaoChar™ 50 has a pH of 7.5–9.0, beneficial for acidic soils; a simple soil test is recommended before large-scale application to alkaline soils.

Q: How can I invest in or partner with Biochar Carbon Removal Africa?
A: We welcome equity investors, agri-dealers, carbon credit off-take buyers, NGO partners, and joint venture arrangements for new production regions. Contact us at hello@carbonremovalafrica.com or complete the enquiry form at carbonremovalafrica.com.
Q: How long does it take to see results?
A: Water retention improvements are visible within the first growing season. Yield improvements typically become significant from the second season. Full long-term benefits — healthier soil biology, reduced fertiliser needs — compound over 3–5 years.
Q: Does biochar replace fertiliser?
A: No. Biochar improves fertiliser efficiency by holding nutrients in the root zone. Many farmers reduce fertiliser input by 20–40% after three seasons while maintaining or improving yields.
Q: Can biochar help with drought and climate change impacts?
A: Yes. Biochar increases soil water retention by 15–25%, extending effective growing seasons and buffering against the erratic rainfall patterns driven by climate change — critical for smallholder farmers in semi-arid regions.
