Biomass power generation depends on a steady and sustainable supply of fuel, known as feedstock. For decades, these plants have turned organic waste into clean, renewable energy. Many of the United States’ legacy biomass facilities were originally built in regions rich in natural and agricultural resources, allowing them to operate successfully for years using abundant local fuel. Today, these same plants are being revived and modernized, supported by new environmental policies, improved logistics and growing demand for carbon-neutral power.
What Biomass Plants Use for Fuel
Biomass feedstock can come from several renewable sources:
1. Forestry Waste:
Wood residues, such as tree trimmings, bark, sawdust and forest floor debris, form the backbone of many biomass supply chains. Utilizing this material not only produces renewable energy but also helps prevent catastrophic wildfires. By clearing dead and fallen trees, biomass operators directly support forest health and complement initiatives such as the Save Our Forests Act, which aims to improve wildfire prevention and sustainable forest management practices.
2. Agricultural Waste:
Crop residues, orchard prunings and processing byproducts can be valuable energy sources. However, open-field burning of this waste, once a common practice, is being phased out due to its air-quality impacts. In fact, California implemented a near-complete ban on agricultural burning in 2025, creating new opportunities for biomass facilities to step in as responsible disposal and energy-conversion partners.
3. Construction and Demolition (C&D) Waste:
Clean wood recovered from construction and demolition activities can be repurposed for biomass energy, diverting large volumes of material from landfills. With proper sorting and processing, this waste stream provides a reliable, low-cost supplement to traditional feedstocks.
Where Biomass Plants Are Located
Many legacy biomass plants were strategically built near forestry and agricultural hubs across the western United States. California, Oregon and Washington host numerous facilities that historically operated in partnership with local timber and farming industries. Because these regions continue to generate large volumes of organic residues, biomass plants remain well-positioned to source nearby fuel while reducing transportation emissions.
How Fuel Supply Chains Work
Feedstock supply is a logistical challenge that requires coordination between landowners, farmers, processors and energy producers. Over the past three decades, companies like Lignum Support have become industry leaders in managing this complex network. With more than 30 years of experience in fiber logistics, Lignum Support specializes in sourcing, aggregating and delivering biomass feedstocks from diverse suppliers to power plants. Their work ensures a consistent, high-quality fuel stream, critical for both plant efficiency and long-term sustainability.
A Sustainable Future for Legacy Assets
As policies evolve and environmental concerns intensify, legacy biomass plants are regaining strategic importance. They offer a proven pathway to reduce wildfire risk, eliminate harmful agricultural burning and transform waste streams into renewable energy. By leveraging experienced partners like Lignum Support and aligning with forest and agricultural management initiatives, these plants can play a central role in the nation’s carbon-neutral energy transition.
