3. Biochar Definition and Properties
• Biochar is biomass that is thermally altered in the
absence of oxygen, ie, it is baked, not burned, and
flammable gasses are released (hydrogen, CO)
• Heat transforms plant carbon (found in cellulose and
lignin) into fused aromatic carbon rings that are very
stable
• Biochars made from different feedstocks at different
temperatures can have very different physical and
chemical properties
9. Reclaiming mine tailings
Hope Mountain Mine near Aspen, Colorado.
100-year old mine tailings contaminated with heavy
metals re-vegetated with biochar in one year.
13. Biochar, the Carbon Cycle and Climate
Change
"If you could continually turn a lot of organic material
into biochar, you could, over time, reverse the history
of the last two hundred years… We can run the movie
backward. We can un-mine some of the coal, un-drill
some of the oil.”
~ Bill McKibben, author, climate activist and
founder of 350.org
18. Soil Benefits - Biochar can replace depleted Soil
Organic Carbon (SOC)
Since the industrial revolution, the conversion of natural ecosystems
to agricultural use has resulted in the depletion of SOC levels,
releasing 50 to 100 GT of carbon from soil into the atmosphere.
19. Biochar Benefits to Soils
• increase soil carbon levels
• improve fertilizer use efficiency
• decrease toxicity of aluminum and other
metals
• increase water holding capacity of the soil
• improve soil conditions for micro and macro
soil life forms (bacteria, fungi, earthworms)
• moderate (usually increase) soil pH
• decrease tensile strength and bulk density of
soil (easier tillage)
20. Iowa – natural biochar
• Iowa soils – some of
the most fertile in the
world
• Why? Natural biochar
from prairie fires
• Root zone excludes
oxygen, producing
char, not ash
21. Biochar retains soil moisture
Iowa corn did better this drought year because the soils
are high in natural biochar. Test plots with added biochar
at Iowa State showed about 15% better water retention.
22. Terra Preta – human-created soils in the
Amazon are 500-6,000 years old
23. Habitat for soil organisms
“permanent compost”
A. Fungal hyphae
B. Bacteria
C. 100-year old char
from forest fire
D. 350-year old char
from forest fire
26. Worms Love Biochar
Biochar works
best when
composted
with other
organic matter
before adding
to garden soil.
This allows life
to colonize the
biochar.

30. Waste that can be turned into biochar
• Paper and cardboard
• Construction waste
• Urban greenwaste (tree trimmings, grass, etc.)
• Fuel-load reduction wood (burn piles)
• Manure
• Human waste
33. Biochar Technology Showcase Events
November 6-9, 2012 in Kerby, OR
• Mobile Biochar Technology Comes to the Southern Oregon
Woods
• Waste-to-wealth technology transforms burn piles from cost
center to profit center – public invited to demonstrations and
lectures offered multiple times during November 6-9
• Hosted by: Carbon Cultures, the Illinois Valley Forest Practices
Committee, the Forestry Action Committee, and Illinois Valley
Business Entrepreneurial Center
• More information at: www.carboncultures.com/carbon-cultures-
showcase-event/
• Biochar Technology Showcase Event planning, publicity,
outreach and logistics by Wilson Biochar Associates
35. Emerging Biochar Markets – Wholesale:
• Soil remediation and water cleanup – mine tailings,
storm water run-off from industrial sites, bio-swales
• Re-vegetation of stream banks and eroded, difficult
sites like forest landings and old roads; tree planting
• Nursery and potting media – tree seedlings, bedding
plants
• Commercial farming and horticulture, including
hydroponics and use in livestock barns for odor control
• Commercial composting – accelerates composting
process, controls odor
• Green roofs
• Urban tree care
36. Emerging Biochar Markets – Retail:
• Home gardening amendments and fertilizer blends –
branded products sold at garden centers
• Artisanal biochar and compost blends sold at local
farmer’s markets
• Bedding and container plants in biochar soil blends
sold at garden centers and nurseries
• Biochar-compost blends sold by the yard or pickup
load direct from composting facilities
• Biochar sold for odor control in horse stalls, chicken
coops, piggeries, etc
38. Popular biochar blends
• Biochar composted with animal manure
• Biochar inoculated with compost tea
• Biochar composted with food waste and bokashi
(anaerobic lactobacillus fermentation)
• Other additives include minerals, NPK, fungi, worm
castings, fish emulsion, urea, etc.
39. How to make money with biochar – some ideas:
• Sell biochar to wholesale markets
• Produce blended biochar products and sell to retail
markets
• Contracts (private, public) to produce biochar for
land remediation, re-vegetation and erosion control
• Forestry and landscape contractors convert yard
waste and logging waste to biochar for large and
small landowners
• Farmers and gardeners can save money by
producing soil amendments for use on the farm
