This is a sample of biochar produced from coarse woody biomass.
What is Biochar?
Biochar is a pure carbon product made from organic material that is generally produced through a process called pyrolysis. Pyrolysis is the decomposition of organic matter at elevated temperatures in an environment with limited oxygen.
Biochar Production and Opportunities for Wood Businesses
Biochar can be produced using woody biomass such as wood chips, sawdust, shavings or bark that is generated from timber harvesting or as a by-product of wood products manufacturing.
Biochar production systems can be classified as either pyrolysis or gasification systems. The pyrolysis of biomass results in three main products: a solid (bio-char), a liquid (bio-oil), and a gas (syngas). Furthermore, pyrolysis becomes self-sustaining as syngas that is produced combusts, generating additional heat for the production process. Gasification on the other hand produces smaller quantities of biochar in a directly-heated reaction vessel with introduced air. Although pyrolysis systems result in higher concentrations of biochar, both production systems can be developed as mobile or stationary units as per the need and availability of the feedstock.

“I have an opportunity to be a voice in the conversation.” As a new member of the Council on Forestry, Jordan Skiff, Fond du Lac public works director and Urban Forestry Council chair, will be an advocate for urban and community forestry, sharing its challenges and proclaiming its benefits. Skiff fills the urban forestry seat vacated by Dr. R. Bruce Allison in December 2016.
Wisconsin Active Together starts 2019 by recognizing fourteen new communities from across the state for their efforts to promote active lifestyles and for their pledge to do more–because in addition to celebrating accomplishments, communities can make resolutions to foster health too! Where we live impacts our wellness and the newly named Wisconsin Active Together Communities, now reaching 1.4 million Wisconsinites across the state, know that even small changes in the landscape and in promoting physical activity can add up to creating lasting changes for everyone’s benefit. And your community can now also apply to be recognized in 2019 for its commitment to advancing strategies for safe places to walk, bike, and be active while getting connected to resources, training, and a peer network of experts.
