THE COMMERCIALIZATION AND ADVANTAGES OFBIOCHAR STOVESAMANDA JOY RAVENHILL ETHOSBIOCHAR ASSOCIATION JANUARY 28, 2012

WHY I LOVE BIOCHARThird Culture Kid- Diverse world-viewsMBA in Sustainability, Bucky Fuller and Systems ThinkingIEA- we have 5 years to turn this ship around! RESOURCES: IEA

WHAT IS A BIOCHAR PRODUCING MICRO-GASIFIER COOKSTOVE?(aka a Biochar Stove)

= THE CHEMISTRY OF PYROLYSISCombustions of gases, not biomassThis all happens in any open ﬁre, stoves organize and controlthe pyrolysis so that is happens uniformly

CHAR PRODUCTIONYou must quench the char before it gasiﬁes to ash.This is Miriam and her Estufa Finca in Costa Rica with oneweek’s worth of char

WHAT IS BIOCHAR?a highly porous and stable charcoal that is applied to soil

THE SECRET OF EL DORADOThe Amazon was once home to cities of millionsThe soil that supported these cities is Terra Preta (DarkEarth) and contains charred kitchen waste. RESOURCES: BBC

COMPOSITIONBiochar is high in stable amorphous graphite domains, as in ithas many tiny pockets.Similar to activated carbon, acts as a soil catalyst.

Decreases nutrientrun offHigh cation exchangecapacityImproves soil tilthCarbon captureRemediates soils ofheavy metals BIOCHAR BENEFITS RESOURCES: IBI

NOT ALL BIOCHARS ARE CREATED EQUALThe same feedstocks can create very different chars atdifferent temperatures.500 C is optimum RESOURCES: MCLAUGHLIN

BIOCHAR STOVE ADVANTAGES:fuels, emissions, value of char, climate solution

ADVANTAGES: FUELSCorn husks, switchgrass, rice hulls, pigeon peasAbundant renewable dry biomassAgro-waste, tree-waste, environmental excesses. RESOURCES: UKBRC report Biochar Innovation

ADVANTAGES: EMISSIONS“Quantum leap” difference from conventional stoves Black Carbon is second major cause of climate change RESOURCES: GIZ Manual

ADVANTAGES: VALUE OF CHARMonitoring tool- when the stove functions well, it produces charCash Value- depending on local prices, $2-$10 dollars a weekSoil Value- increases resiliency to extreme weather events

In Costa Rica: IS IT WORTH IT?Each stove produces about 1.5 Kilos per day of charThe char is bought back for 30 cents a kiloResulting in an income of .45 cents a day for the households

ADVANTAGES: CLIMATE SOLUTIONOffset up to 12% of GHG Reduces Black CarbonClimate AdaptationCarbon-negative energy RESOURCES: Nature Communications
