Forest Biomass in the United States: What Scales and What Doesn’t

by Alexander A. Koukoulas (A2K Consultants/Biofuels Digest) Forest biomass has long been positioned as a cornerstone of the U.S. bioeconomy. The logic is compelling: abundant working forests, a mature forest products industry, deep technical expertise, and increasing pressure to decarbonize materials, fuels, and energy. Yet despite decades of policy support, R&D investment, and commercial ambition, outcomes across biomass pathways have diverged sharply.

Some uses of wood scale reliably and profitably. Others—particularly wood-to-fuels and commodity chemicals—remain elusive at commercial scale. Understanding why is essential if the forest sector is to move from recurring promise to durable progress.

The System Reality: Where Wood Actually Goes

The United States harvests approximately 430–450 million green tons of wood annually, almost entirely from working forests. This volume supports one of the largest forest products systems in the world, but its structure is often misunderstood.

The overwhelming majority of harvested wood flows into two system-forming market pillars:

Solid wood products for construction (e.g., lumber, plywood, OSB, engineered wood, etc.)
Pulp & paper, including packaging, tissue, and specialty grades

Every other biomass pathway—pellets, chemicals, fuels, carbon, etc.—depends on the economic gravity of these two pillars. They pay for forest management, sustain harvesting and logistics infrastructure, and generate the residual streams that downstream users rely on. Figure 1 illustrates this reality clearly: construction materials and pulp & paper together account for nearly ninety percent of U.S. wood use, while fuels and chemicals remain marginal by volume.

The Cascading Use Principle and Why the Two Pillars Matter

The dominance of wood products and pulp & paper is not accidental. It reflects what is often described as the cascading use principle: wood is first directed to its highest-value, longest-lived applications, and only later—through residues, recycling, or end-of-life recovery—flows into lower-value uses such as energy or fuels.

...

Why Housing Materials and Pulp & Paper Continue to Dominate

Solid wood products succeed because they convert high-quality logs into high-value materials with strong capital efficiency and deep, liquid markets.

...

Pellets: The One New Market That Truly Scaled

Wood pellets represent the clearest example of successful biomass market expansion in the past two decades. U.S. pellet production—largely in the Southeast—scaled rapidly due to export demand, particularly in Europe.

Pellets fit naturally within the cascading use framework. They rely primarily on low-grade fiber and residues, require moderate capital investment, use proven technology, and benefit from long-term offtake contracts.

...

Wood-Based Chemicals: Real, Profitable, and Constrained by Design

Wood-derived chemicals, such as tall oil derivatives, lignosulfonates, cellulose ethers, nanocellulose, and specialty sugars, all occupy defensible market positions. Their common characteristics are telling: integration with existing mills, focus on higher-margin applications, modest incremental capital, and acceptance of limited scale. These pathways sit mid-cascade: above fuels and energy, but below primary materials.

...

The Persistent Challenge of Wood-to-Fuels

For decades, wood-to-fuels has been framed as the logical next step for forest biomass. The technical pathways—thermochemical, biochemical, and hybrid—are well understood. The challenge lies elsewhere.

Key structural barriers include high delivered feedstock costs ($60–120 per dry ton), capital intensity often exceeding $1–2 billion at scale, logistics complexity tied to low bulk density and geographic dispersion, and a fundamental market mismatch: fuels are low-margin, price-volatile commodities.

Within a cascading system, fuels occupy the lowest-value rung.

...

A Note on Purpose-Grown Energy Crops

...

Purpose-grown crops remain subject to the same fuel-market realities—low margins, price volatility, and policy dependence—while introducing additional land-use, agronomic, and logistics considerations. As a result, they represent a fundamentally different land-use strategy rather than an extension of the forest-products system described in this paper.

...

Where they are deployed, they should be evaluated independently from forest biomass pathways and not assumed to substitute for the cascading use of wood.

Biofuels as a Price-Support Mechanism, Not a Volume Solution

This does not mean wood-based fuels lack strategic value. In fact, their greatest contribution may not be as large-volume outlets for biomass, but as marginal, high-value demand that increases the overall ability of the system to pay for woody residuals.

When low-carbon fuels are tightly integrated with existing mills, infrastructure, and supply chains—and when policy support is durable rather than speculative—they can act as price-support mechanisms within the cascading system. In this role, fuels complement higher-value material uses rather than displacing them.

...

Carbon Changes the Equation but Not the Fundamentals

Carbon markets and policies introduce an important new variable. Forest carbon credits, bioenergy with carbon capture, and carbon utilization pathways can materially affect project economics. In some cases, carbon revenues rival or exceed traditional product margins.

However, carbon does not overturn the cascading-use principle. It works best when layered onto existing, economically sound assets, not when used to justify diverting biomass from higher-value, longer-lived material uses.

...

A Data-Driven Path Forward

The data points toward a more grounded strategy for the U.S. forest bioeconomy:

Protect and modernize system-forming sectors. Construction materials and pulp & paper are the anchors of cascading use and sustainable forest management.
Prioritize by-product upgrading over whole-tree conversion. Liquors, lignin, hemicellulose streams, biogenic CO₂, and waste heat offer the best risk-adjusted opportunities.
Be disciplined and selective about fuels. Where wood-to-fuels makes sense, it will be at modest scale, co-located with existing infrastructure, and positioned as a price-support mechanism.
Use carbon to de-risk, not to rationalize. Carbon revenues should strengthen competitive assets, not undermine higher-value material uses.

Conclusion

The United States does not lack forest biomass potential. What it has often lacked is a functional alignment between biological realities, industrial systems, and capital markets.

...

In this context, selectively deployed biorefineries, particularly those producing low-carbon fuels, can play a constructive role by relieving local bottlenecks and establishing price support for stranded residuals.

Crucially, the constraint on scaling these pathways is not always operating economics. In many regions, feedstock and variable costs are already competitive. The gating factor is capital: high upfront investment requirements, long construction timelines, and the compounding effects of policy and technology risk.
