The Carbonizer

Groundbreaking Technology Being Used to Reduce Wildfire Risk

December 21, 2023

Thursday, December 21, 2023 (Castro Valley, CA) – Wildfires are a significant hazard in the Bay Area. But in the East Bay, a new machine called a carbonizer is being used by the East Bay Regional Park District to fight fire with fire, literally. The carbonizer was recently started up for the winter season.

The carbonizer is currently being used at Anthony Chabot Regional Park to dispose of vegetation from a large 365-acre fuels reduction project. In 2020, the Park District found over 1,500 acres of dead and dying trees within its parks caused by drought stress and climate change.

The carbonizer burns organic matter at extremely high temperatures (about 1,300 degrees Fahrenheit) using very little oxygen to dispose of vegetation, which results in very low greenhouse gas emissions. The carbonizer is a climate-friendly disposal method, especially compared to the conventional open pile burning or transporting loads long distances off-site in diesel trucks.

“The project at Anthony Chabot Regional Park is a first-of-its-kind project in the Bay Area,” said Park District General Manager Sabrina Landreth. “As the largest regional park district in the nation and a local leader in wildfire prevention, we knew we needed to find an innovative solution for disposing of the vegetation from our fuels reduction projects.”

The resulting material, called biochar, is being used within the Park District as a soil enhancer. Biochar from the carbonizer is being used at the Park District’s Ardenwood Historic Farm in Fremont to enhance soil health and crop productivity, amongst other District locations.

“The carbonizer is an innovative fuels reduction tool to address wildfire risks and combat climate change,” said Chief Aileen Theile. “We are always looking for innovative ways to address wildfire dangers and reduce wildfire risks for the community.”
