Biomass Pilot Project

What 

The Biomass Pilot Project was a groundbreaking initiative processing small diameter (unmerchantable) wood from forest health and fuels reduction projects into something useful: biochar. Using two cutting-edge Tigercat 6040 Carbonizers from Earth Foundries, Inc. This process didn't just clear up space and reduce fuel loads in the county, it created biochar, a carbon-rich, porous, charcoal-like substance that can improve soil health, retain water, filter impurities, sequester carbon and enhance agricultural productivity. 

By partnering with Mountain Enterprises, Inc., a dedicated grappling truck service ensured material was efficiently transported to the processing site. The goal was to process 5,000 tons of woody material from within the County, helping reduce wildfire risks and promote healthier forests. This project was about turning today’s challenges into tomorrow’s solutions. 

Where 

The Biomass Pilot Project took place on La Barr Meadows Road, Grass Valley on County-owned land adjacent to the Nevada County Operations Center. This central location was chosen for its easy access and operational efficiency, making it the perfect hub for collecting and processing woody debris.

Material was sourced from predetermined priority areas including Firewise Communities identified in the 2024 Evacuation Study. Additional opportunities for Nevada County residents to dispose of hazardous vegetation are available through 2025 Community Green Waste Events.

When 

The project officially commenced in November 2024 and ran through May 2025. Over this seven-month period, the project operated continuously to process woody debris, providing sustainable and cost-effective solutions for biomass management.

Why It Matters

The Biomass Pilot Project is a significant step toward enhancing climate resiliency and improving emergency preparedness

Safer Communities

By reducing excess woody biomass near the source, wildfire risks are lowered, making Nevada County safer for everyone. Fewer miles traveled for wood transport also means less heavy equipment on local roads, improving overall safety.

Cleaner Environment

This project helps cut down greenhouse gas emissions by minimizing transportation and enhancing wood management methods. In addition the biochar that is created improves soil health and sequesters carbon, supporting a healthier environment for future generations. 

Stronger Forests, Stronger County

Transforming woody biomass into biochar gives forest material a productive new life, strengthening forest ecosystems. Healthier forests mean greater resilience against wildfires and a stronger, more vibrant Nevada County.

Goals


  • Reduce local wildfire fuels by 5,000 tons and convert into value-added biochar.
  • Distribute biochar throughout the county for a variety of applications including agriculture, composting, landscaping, stormwater remediation, and land and forest restoration. 
  • Determine the economic feasibility and environmental benefit of the carbonizer technology.
  • Identify best practices and lessons learned to guide future projects and programs.


Project Funders & Partners

The Biomass Pilot Project was funded through a combination of federal and corporate support. A significant contribution of $233,592 comes from the American Rescue Plan Act (ARPA) via an allocation from the California Governor’s Office of Emergency Services (OES), aimed at strengthening community resilience and enhancing wildfire prevention. This funding allows Nevada County to invest in innovative, sustainable solutions to manage forest materials while reducing wildfire risks. Additionally, Pacific Gas and Electric Company (PG&E) has contributed $100,000 through its Electric Program Investment Charge (EPIC) 3.47 initiative, which focuses on advancing biomass conversion technologies and improving wildfire safety.

Together, these partnerships are driving forward Nevada County’s commitment to protecting communities, improving forest health, and promoting sustainable vegetation management.
