Methow Valley biochar project funded in Senate budget proposal

[Fun CH]

The article didn't say where in the Mazama this project would be located.

Or is it going to be located on the Poor Side of Town?

In the Methow Valley, a nonprofit will soon initiate a research and demonstration project to produce biochar designed to benefit local agricultural soils and sequester carbon. According to Regeneration International, “Biochar is a charcoal-like substance that’s made by burning organic material from agricultural and forestry wastes (also called biomass) in a controlled process called pyrolysis. Although it looks a lot like common charcoal, biochar is produced using a specific process to reduce contamination and safely store carbon. During pyrolysis organic materials, such as wood chips, leaf litter or dead plants, are burned in a container with very little oxygen. As the materials burn, they release little to no contaminating fumes or smoke. During the pyrolysis process, the organic material is converted into biochar, a stable form of carbon that can’t easily escape into the atmosphere. The energy or heat created during pyrolysis can be captured and used as a form of clean energy.”

The goal is to identify optimal conditions for processing unmerchantable Douglas fir and ponderosa pine trees (as well as other forestry waste) common to our region into biochars designed for a variety of applications. The types of materials to be processed will be the same biomass that, if left in the forest, would keep raising our wildfire risk and threatening long-term forest health. Not only would removing these materials reduce our wildfire risk, designed biochar is known to have soil-enhancing qualities if applied to agricultural lands. In improving soil quality, biochar can be mixed into soil for agricultural purposes or home gardening. It has been proven to enhance soil structure, increase water retention, and decrease acidity, among other benefits. This step keeps carbon and other greenhouse gas emissions from being released into the air through wildfire or slash burning and stabilizes them into the biochar, which can be mixed into the soil for agricultural benefits.

Pyrolysis is a super heating process that can convert excess forest debris into biochar, which can be used to sequester carbon into the ground and improve soil for agricultural production (cprsx.com).


Using pyrolysis to produce biochar


According to Washington State University’s Center for Sustaining Agriculture and Natural Resources, “Pyrolysis is the thermo-chemical conversion of dry organic materials (i.e. woody wastes) into bio-oil, syngas, and biochar.” The U.S. Biochar Initiative further describes the pyrolysis as using a pyrolizer to super-heat biomass “in the absence of oxygen at high temperatures (350-700° C) in specially designed furnaces. The most sustainable feed stocks are what's now considered waste: excess manure, wood debris, construction waste, slash from forest thinning, food processing waste, residue from methane digesters or urban tree trimmings. Most of this would be left to rot, be open-burned or dumped in a land fill. In this modern method, volatile gases, hydrocarbons and most of the oxygen and hydrogen in the biomass are burned or driven off and captured, including greenhouse gases. These captured emissions are known as syngas (synthetic gas) and can be used like natural gas. Liquids, called bio-oils, are also captured creating another source of energy, leaving carbon enriched biochar.” During pyrolysis, it is also possible to use the heat generated as a source of power. In the Methow Valley, C6 Forest to Farm’s plans start with chipping woody material provided from forest health and Firewise treatments and feeding it into a leased research pyrolizer atop a 5-by-12-foot utility trailer. A range of designed biochars, produced by varying the processing conditions, will be used in field trials to optimize the benefits of biochars in locally common soil types, and potentially, for other uses such as wastewater remediation. Following this research phase, C6 aims to establish a modular pilot plant with an initial capacity to annually process about 25,000 tons of forest waste into 6,000 tons of biochar and supply it to our farmers. The carbon sequestered by doing so would be the equivalent of about 22,000 tons of carbon dioxide. There is also a potential role in creating good sustainable family-wage jobs. This would be a win-win for our environment and our economy.


C6 Forest to Farm strategy


I first learned of biochar while securing passage of my Senate Bill 6055 in 2018 to allow the City of Leavenworth to dispose of brush and yard waste. Creating biochar was an option considered during the legislative process that year but not included in the final bill that became law. City of Leavenworth officials provided me that bill idea during a listening tour earlier that fall. One year later, I met Tom and Gina McCoy during a visit to Twisp for my 2019 listening tour. When Tom mentioned his interest in biochar, I was proud to have some basic understanding. He participated again in my 2020 listening tour to further the discussion about his project. The vision provided to me seemed pretty compelling and could potentially be environmentally and economically beneficial while also reducing our risk of wildfire. This seems like a creative and worthy endeavor, which is why I am partnering with the organization to seek a modest amount of funding in the state operating budget to assist in its Methow Valley demonstration project.
