Ethos 2017

Small scale biochar production and use was discussed at the annual conference of the Engineers in Technical and Humanitarian Opportunities of Service (www.ethoscon.com)

An estimated 2.5 billion people worldwide cook their meals with biomass. ETHOS is an international group of individuals and organizations that promote improved cooking stoves for health, safety, and household energy. The Toplit Updraft or TLUD stoves are efficient and can produce biochar as a co-product of household energy.

Participants were interested in how biochars can be used to remediate soils and improve agriculture. Norman Baker, Sequim, showed how a 55 gallon TLUD can be used to make biochar for growing vegetables and improving nutrition. Paul Anderson (drtlud.com) described 12,000 TLUD stoves in India that product 10 tons of biochar each day. Users receive cash from selling the biochar to a German company, atmosfair gGmbH, which recovers carbon offsets for the energy savings and char to help fund the energy efficient cooking stoves. Art Donnelly, Seachar (seachar.org) demonstrated a new biochar making stove and described how biochar from cooking stoves has been used by coffee workers in Costa Rica. ETHOS participants are among the 1600 partners of the Global Alliance for Clean Cookstoves (cleancookstoves.org)
