Biomass Carbonization - General
A plant that can convert biomass into charcoal (biochar).
Sludge
Food waste
Agricultural residue
Scrap wood
Carbonization plant
Water hyacinth etc.
Residual biomass Biochar
Waste management Agriculture / Environment / Energy
Soil conditioner
Natural fertilizer
Fuel
Sludge
Kitchen garbage
Water hyacinth
Agricultural residue
Animal waste
etc.
Residual biomass Carbonization plant Biochar (+wood vinegar)
Waste management Agriculture Energy Environment
• Patented • Energy- and cost-efficient • Wide range of processable ingredients

Biochar – as fuel
Smokeless, no tree cutting, carbon neutral

Soil microbial activity
Water retention
Nutrient (N, P, K, etc.)
Nutrient retention
Nutrient assistance
Repellent
Ideal for agriculture
Carbonization
Wood vinegar =organic acid
Biochar =porous
→Drought resilient
Cattle disease control
Biochar – as powerful soil conditioner
→ Health?
→ Livestock?

• What are major sources of raw material?
• Waste separation at source? Any incentive?
• Pollutants (heavy metals, plastics, etc.) to be avoided
• Simple and optimized methods/systems in Kenya?
Analysis, R&D, test marketing etc. to be done with partners
Key to success = various partners
