Unikode SA of Haiti is one of the world's largest producers of vetiver oil (30 MT per year). Its vetiver plant source is from many thousands of small holder growers in the Les Cayes area. Unikode has taken three important steps: (1) its production and processing systems have become eco certified (2) it has introduced the Vetiver System using vetiver hedgerows for erosion control on vetiver (for oil) grower farms and (3) is creating a briquetting program using distilled vetiver root and vetiver leaf biomass. In summaryl:
(1) Farmers sell Vetiver leaf biomass to briquette production facility
(2) Vetiver oil distilleries sell Vetiver root biomass waste to the briquette production facility
(3) Briquette production facility sells fuel briquettes to Vetiver farmer groups
(4) Farmer groups carbonize fuel briquettes
(5) Farmer groups form Farmer Briquette Businesses and sell carbonized fuel briquettes to charcoal wholesalers and directly to the market
(5) Households, small businesses, and the Les Cayes community at large purchase carbonized fuel briquettes.

If Unicode can do this, then others in other countries should be able to do the same - especially from the huge amount of potential leaf biomass from vetiver hedgerows on small farms.
Biomass briquettes can be burned in gasifier cook stoves and the resulting char can be used as charcoal fuel or added to soil as biochar to increase nutrient and water retention.
