Haiti Reconstruction

Rebuilding Haiti must start from the ground up, with agricultural education

Cookstoves, Biochar, Vetiver & Biomass fuels


Cookstoves, Biochar, Vetiver & Biomass fuels

We are looking for Biochar experts and cookstove engineers to see the need for using vetiver and for Haiti Reconstrucion and Vetiver experts to see the need for biochar and cookstoves that produce it.

Haiti needs billions of vetiver slips for hedgerows to save the land, if people see additional monitary reasons to plant it.  Such as selling cooking fuel instead of making charcoal.  They will be willing to plant more.

Once it is established they will realize it is producing more food as the biochar fertilizes the soil.

Biochar increases water holding capacity, nutrient retention, and creates beneficial conditions for soil microbial life thereby increasing soil quality and plant productivity.

Biochar production that can generate electricity or produce heat for cooking, boilers for manufacturing, and refrigeration through absorptive refrigeration technologies.

It effectively sequesters carbon from the atmosphere safely locking it in the soil restoring Haiti’s climate

We need experts in these fields to come together discussing best solutions using the enormaous amount of vetiver grass cuttings we should have some day.

Suggested subjects are:


Building efficient stoves & ovens for family, institutional and commercial cooking.


Boiler for commercial food processing. 


Biochar from human waste under anarobic conditions to make terra preta


Any other offshoots from Vetiver Grass uses and Biochar production you can think of

Making vetiver grass into Briquette pucks or Pellets? 1 Reply

Most TLUD stove designers seem to prefer wood or grass pellets rather than pressed briquette pucks. My experience in Haiti tells me that in order for new programs to succeed they must be implemented…Continue

Moringo Oleifera, sometimes known as the Horseradish Tree, is a fast-growing, drought-resistant tree distributed world-wide including Haiti.. The Moringa Tree has some unique propriety, the seed cake can be used to purify water. Crushed Moringa seed kernel and seed cake are very effective in water purification. The seeds from the tree are crushed and poured into an open well, which makes all the suspended dirt particles like silt, solids, bacteria and other microorganisms stick together. Once the particles have coagulated, they sink to the bottom of the water and the rest of the water will be left clear. The process can also be applied at home for the treatment of unclean river water as this is cheaper and an environmentally friendly.  The meal cake is rumored to be unsuitable as an animal feed as it is supposed to contain alkaloid and a saponin, but it is a suitable fertilizer. Yields are high, estimated at 3.0 tonnes seed/hectare when compared to average yields of sunflower at 2.0 tonnes seed/hectare. The drought tolerant nature of the tree makes it particularly suited to marginal areas and this means that it should not need to displace land used for existing food crop cultivation.

Moringa Oleifera is known as benzolive in Haiti, it is much to precious to use for oil extraction. 

Read more about it on its own page under 2 replenishsoil Reforest tab above


We promote it planted between the rows of vetiver, since it is such an important plant.  It's best qualities are for lactation both in humans and animals.  Animals thrive eating this plant even helping their immune systems.

Wanted to save this important info from Criss Juliard

I wanted to jump in here regarding the sustainable source of biomass. Both Vietnam and Haiti have large quantities of biomass, and it is not only free, but easily accessible; it is the massive leaves that develop well from the Vetiver plants used for embankment stabilization, watershed management, disaster mitigation, wastewater treatment and other. Large nurseries provide the raw material. All applications and nurseries of Vetiver (Vetiveria zizanioides) need to trim the leaf blades of the plants to stimulate root growth. The leaves can be used for mulch and ground cover, but disintegrating slowly. “The (Vetiver) leaf blades are  relatively stiff, long and narrow-up to 75cm long and downward tough  along the  edges.”  Google “Vetiver Vietnam fuel” and you get 195,000 references. “Vetiver has an energy value of about 55% of that of coal” http://www.greenfueltech.net/vetiver.htm, The person to contact is Tran Tan Van, Coordinator of the Vietnam Vetiver Network. Dr. Tran Tan Van works out of the Research Inst. of Geology and Mineral Resources in Hanoi.

He will be able to point you to important quantities of the leaves, that when dried makes excellent stove pellets. http://www.ctu.edu.vn/VetiverVN/Proceedings/Content/Full%20Web/2%20.... contact: van@vigmr.vn


Equally there has been other movements towards getting vetiver briquettes produced in the SW parts of Haiti under the Future Fuels of Haiti organization:



Thank you all for keeping this group updated on the progress made in briquette trials and experience; the Vetiver Network International (TVNI) is most interested.


Kind regards,
