Francesco is an engineer and appropriate technology advocate. He was the co-founder and Director of the Norwegian Center for Appropriate Technology in the 1970s. His interest in appropriate technologies led him to attend the ETHOS (Engineers in Technical and Humanitarian Opportunities of Service) Conference in 2011 and through that experience he has been associated with several NGOs in the northwest that focus on promoting clean cook stoves which produce biochar.
He collaborated with a mushroom farmer in Sequim to develop a commercial gasifer stove used to pasteurize straw and make biochar. For the past three years he has been involved with the Port of Port Townsend designing and building biochar filters to remove heavy metals form stormwater runoff. Most recently Francesco has teamed with several local farms (Jefferson County) in the production and incorporation of biochar. This includes trials conducted at WSU’s Twin View Ranch on Marrowstone Island.
Workshop 1 Title:
Workshop 1 Description:
Attendees will be presented with an overview of biochar production and uses, including local examples. Biochar is produced in micro-gasifier stoves, kilns and industrial processes. Micro-gasifier stoves create cooking heat while producing biochar. On an industrial scale the Port Townsend Paper Corporation produces biochar as a byproduct of its steam producing boiler.
Biochar can be used as a soil amendment and filter media for the removal of heavy metals. Experiments are being done locally using biochar for growing organic crops, improving garden soil and sequestering carbon for hundreds of years. Details of an ongoing project at the Port of Port Townsend where biochar filters are removing heavy metals from stormwater runoff will be presented. Trials at several local farms that both produce and incorporate biochar will be highlighted.

Workshop 2 Description:
Small micro-gasifier stoves will be demonstrated. These stoves can be use for emergency preparedness, backyard cooking and to produce biochar.
