Technology
The GBG Technology Platform — Purpose-Built for African Conditions
Our technology platform combines proven kiln engineering with digital monitoring and supply chain management to deliver scalable, efficient, and verifiable biochar and charcoal production across Uganda.
Retort Kilns
Closed-system kilns that capture and recycle combustion gases, dramatically reducing emissions while achieving 25–30% charcoal yields — double the efficiency of traditional earth kilns.
Mobile Metallic Kilns
Transportable kiln units deployed directly to plantation sites, eliminating long-distance biomass transport and enabling decentralised production close to the raw material source.
Biomass Drying Systems
Solar and waste-heat drying infrastructure reduces biomass moisture before carbonisation, significantly improving kiln efficiency, product quality, and carbon yield per batch.
Biochar Processing
Post-kiln screening, sizing, and optional microbial inoculation to produce premium soil amendment products meeting EBC quality specifications for agricultural and carbon markets.
Performance Comparison
