Freres Lumber Co., Lyons, Or., has published its first Environmental Product Declaration for its Mass Ply Panel (MPP). Product specific information in this report was independently validated by the internationally recognized standards organization, ASTM International.
EPDs provide a standardized, objective assessment of the relative environmental impact of a product from “cradle-to-gate,” beginning with material sourcing and reforestation practices, to material transportation all the way through to the final product manufacturing and packaging.
ASTM independently verified and validated Freres’ MPP EPD information, finding that MPP meets necessary standards for builders, architects and engineers alike to meet various green building and LEED standards.
According to Maureen Puettmann, director of operations for CORRIM, who wrote and edited the report, more than 51% of the energy consumed in producing MPP is sourced from renewable fuels with a net embodied carbon for MPP of –742 kg of CO2e. MPP holds this carbon, keeping it from being released into the atmosphere for the lifetime of the panel.
The EPD validates that MPP creates less global warming potential upon manufacturing than its competitors in the same category. Additionally, MPP uses approximately 20% less wood than CLT and can be constructed from small diameter timber (as small as 5” in diameter) to create large format panels.
