The Engineering

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.

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.

Impact

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.
