  • Third-party forest certification based on standards developed by the Forest Stewardship Council (FSC) is the best way to ensure that wood products come from well-managed forests. Wood products must go through a chain-of-custody certification process to carry an FSC stamp.

    Manufactured wood products can meet the FSC certification requirements with less than 100% certified wood content through percentage-based claims (30% certified content is required if only virgin wood fiber is used; certified-wood content as low as 17.5% is allowable if the rest of the fiber content is from recycled sources).

    With a few special-case exceptions, FSC-based certification is a requirement for GreenSpec inclusion of any nonsalvaged solid-wood product and most other wood products. A few manufactured wood products, including engineered lumber and particleboard/MDF, can be included if they have other environmental advantages--such as absence of formaldehyde binders. Engineered wood products in GreenSpec do not qualify by virtue of their resource efficiency benefits alone (for more on this, see EBN, Vol. 8, No. 11).

GreenCore Plyform® FSC-certified concrete forming panels are available in BB grade and 19/32" and 23/32" thicknesses. These panels are edge-sealed and oiled with NOX-CRETE Concrete Forming Oil, a petroleum-based product made by Chemtrec in Omaha, Nebraska. The mill also produces industrial plywood. GreenCore Plyform is certified using partial-content rules for certification (some fiber used in the mill comes from land not owned by the company), but 100% FSC-certified product can be provided. Roy O. Martin Lumber Management, LLC (ROM) is the first company to receive FSC-certification in the state of Louisiana, and they offer the first FSC-certified OSB and FSC-certified utility poles.

Cement production requires about 6 million Btus per ton of cement produced; most of that energy is used in coal-fired cement kilns, resulting in high carbon dioxide, nitrous oxide, and sulfur emissions. It’s been calculated that producing a ton of cement releases a ton of CO2 into the atmosphere.

Judicious use of concrete is an important green-building consideration. Concrete pier foundations greatly reduce concrete use compared with full-height frost walls; while most commonly used for decks, outdoor stairs, and the like, they are also used for entire buildings and can be particularly appropriate on ecologically fragile sites.

Products listed here are less resource-intensive than conventional concrete-forming products, permit the construction of foundations using less concrete, or are made from recycled-content materials or plywood certified according to the standards of the Forest Stewardship Council (FSC).

Concrete construction tubes made from recycled paper, in conjunction with recycled-plastic or fabric footing forms, offer a quick, resource-efficient means of pouring structural piers.
