Canadian biomass reserves for biorefining

Area of Science:

• Biomass energy
• Sustainable biorefining
• Canadian forestry and agriculture

Background:

• Lignocellulosic biorefining requires sustainable biomass feedstock.
• Current supply chains for forest and agricultural residues are vulnerable.
• Expansion of biomass reserves is crucial for biorefinery development.

Purpose of the Study:

• To assess the potential for biomass reserves in Canada.
• To identify strategies for expanding biomass feedstock availability.
• To inform policy for supporting biorefining initiatives.

Main Methods:

• Quantifying feedstock potential from forest-harvest residues (residue removal, disturbance isolation, precommercial thinnings).
• Estimating feedstock potential from energy plantations on marginal farmland.
• Analyzing supply chain vulnerabilities and management techniques.

Main Results:

• Forest-harvest residue removal, disturbance isolation, and precommercial thinnings could yield 20-33 million metric tons/year of feedstock.
• Energy plantations on marginal Canadian farmland could produce an additional 9-20 million metric tons.
• Biomass reserves can support first-generation bioethanol production.

Conclusions:

• Biomass reserves are essential for establishing Canadian biorefineries.
• Innovative management and energy plantations can significantly increase feedstock supply.
• Policy reforms are recommended to support biomass reserve development for bioethanol and coproducts.
