Wood → Gas → Pure Carbon.
Traditional bush charcoal is inconsistent, smoky and short-burning. Luvatsi is built differently. We use pyrolysis — the controlled thermal decomposition of wood at 600–900 °C inside a sealed, low-oxygen chamber. This drives out water, sap and volatile gases, leaving a hardened, carbon-rich skeleton of the original wood.
Phase 01
Raw Feedstock
Sustainably sourced biomass is prepared and loaded into the sealed pyrolysis chamber.
Phase 02
Thermal Reform
Temperature climbs to 600–900 °C in a low-oxygen environment. Water, sap and volatile gases vaporise and escape — combustion cannot occur.
Phase 03
Pure Carbon
What remains is a hardened, carbon-rich skeleton of the original wood — dense, dry, and ready to burn clean.
Pyrolysis temperature range
Luvatsi's process runs in the 600–900 °C window — the sweet spot where volatiles are fully driven off and the carbon lattice locks in for maximum caloric output.
Why it burns cleaner.
56%
Fewer toxic emissions
Less indoor air pollution — a direct win for the person cooking, usually a woman or child.
58%
Less fuel per meal
Every meal costs less charcoal. Every bag lasts longer. Household energy budgets drop 30–50%.
56%
Faster cook time
1 litre boils in 5 minutes. Cook time drops by more than half versus a traditional charcoal stove.
Every bag protects Eswatini's forests, air & families.
Deforestation
Higher caloric output means fewer trees felled per household per year — easing pressure on Eswatini's woodlands.
Indoor Air
Volatile compounds are removed during pyrolysis, so what actually burns in your kitchen is cleaner — protecting the lungs of women and children.
Carbon
Programme potential of 10,000–20,000 tonnes CO₂e avoided annually through the Alliance's clean-cooking transition.
The ECOA Pro stove-pot evidence.
The same science scales up. In institutional kitchens the ECOA Pro stove-pot pairs an insulated 65%-efficient pot with a sealed firebox, delivering up to 72% fuel savings and 46% faster cooking against a three-stone fire.
