The Compost Coalition of Sonoma Co. invites everyone to a BioChar demonstration hosted at Old World Vineyard, Forestville, Ca.
BioChar Coalition x NapaChar will share about the science and practices of turning our seasonal burn piles of biomass into biochar, by using the process of pyrolysis to safely store carbon. The team will demonstrate how to produce biochar from vines / prunings using a Flame-Cap kiln.
Eric Mayer of NapaChar earned a PhD in Environmental Engineering from Stanford University, where he studied fluid mechanics and hydrology and published research improving global climate simulations. Upon graduation, Eric went looking for a more immediate way to address the climate crisis, and after a circuitous path involving algae ponds and backyard burn pits, discovered biochar and flame cap kilns, and Eric's company Napachar was born. Today, you can find Eric and Napachar in the vineyards and forests of Napa and Sonoma, diverting pulled vines and forestry slash from burn piles to bake in their biochar kilns, returning "waste" carbon to the soil.
Peter Roediger has extensive field experience with flame cap carbonization and an ever growing relation with fire on the land. His years of backpacking and search and rescue launched him into the role of stewardship as a sawyer and igniter alike. He heads the coast chapter of the Biochar Coalition and is always looking for more implementation opportunities for stable carbon creation.
We will spend the afternoon together learning about the science of biochar and participating in the burning, quenching and inoculation practices.
There is a recommended donation, sliding scale for the day.
