WoodWorks, a proponent of large-scale wood construction in the U.S., launched an updated version of its free carbon calculator, adding more options for buildings made from cross-laminated timber (CLT) and other mass timber products. The addition reflects rising interest in large scale wood building construction.
WoodWorks, which receives finding from the U.S. Department of Agriculture as well as timber companies and forest products manufacturers, promotes use of wood products as a means to store carbon, instead of building materials such as cement and steel that require fossil fuel energy to manufacture, a move that can help reduce greenhouse gases.
“The carbon calculator is a useful tool for building owners and designers who’d like to gain insight on the environmental value of alternate designs,” said Bill Parsons, Senior National Director of the Architectural & Engineering Solutions Team at WoodWorks. “It also provides information that allows them to express the carbon benefits of their wood building projects.”
To calculate the carbon benefits of a wood building, users access the carbon calculator at www.woodworks.org/carbon-calculator and enter nominal wood volume information. The calculator then estimates:
• How much time it takes U.S. and Canadian forests to grow that volume of wood
• The amount of carbon sequestered in the wood products, and
• Greenhouse gas emissions avoided by not using more fossil fuel-intensive materials.
• It also uses the U.S. Environmental Protection Agency’s Greenhouse Gas Equivalencies Calculator to equate the total carbon benefit to number of cars off the road and home operational energy.

The US Environmental Protection Agency (EPA) has finalized the new rules on formaldehyde emissions for manmade wood products. Under the new regulations, Third Party Certification (TPC) bodies currently approved to provide certification for the California Air Resources Board (CARB) formaldehyde standards will be entitled to provide certification for the new Toxic Substances Control Act (TSCA) formaldehyde emissions standard. Permission will be granted for a period of two years without the requirement for further approval. After this period, TPC will require accreditation by the EPA for TSCA Title VI certification.
The grace period will make it easier for manufacturers seeking a certified TPC and benefits continuity as the new set of rules, entitled 40 CFR 770, are based on CARB standards. The Formaldehyde Standards for Composite Wood Products Act, signed by President Obama in July 2010 amended the TSCA with the addition of Title VI and required the EPA to create regulations on formaldehyde in manmade wood products. After a lengthy period of consultation, new rules have been announced, which will come into effect one year after publication in the Federal Register.
Regulations 40 CFR 770 stipulate requirements for product labeling, compliance documentation, and for the conditions for approval of TPC and Accreditation Bodies (AB). The regulations also set out the requirements for formaldehyde emissions from composite wood products, component parts and finished goods.
Composite wood producers need to be certified through a program that includes product testing for emission standards and production facility inspections, including requirements for processes and record keeping. The emission standards are based on test method ASTM E1333-10.

The Environmental Protection Agency rolled out a formaldehyde emission standard, working with the California Air Resources Board (CARB) in setting the rules that are mandated by Congress.
The EPA moved to reduce exposure to formaldehyde vapors from laminate panel and engineered wood products produced domestically or imported into the United States. The agency worked with the California Air Resources Board to make its final national rule consistent with California requirements for composite wood products.
One year after the rule is published, composite wood products that are sold, supplied, offered for sale, manufactured, or imported in the United States will need to be labeled as TSCA Title VI compliant. These products include: hardwood plywood, medium-density fiberboard, particleboard as well as household and other finished goods containing these products.
The action was triggered in large part by discovering that Lumber Liquidators’ flooring supply from China has been labeled CARB compliant though it was not. Lumber Liquidators has since settled with CARB and the Consumer Products Safety Commission over its liability for the matter. The new rule requires other sellers of laminate panel to meet the CARB standards for formaldehyde exposure.
EPA says the new rule will level the playing field for domestic laminate flooring manufacturers who have a high rate of compliance with the California standard and will ensure that imported products not subject to California’s requirements will meet the new standard and thus, not contain dangerous formaldehyde vapors.”

U.S. Environmental Protection Agency (EPA) finalized changes to Clean Air Act standards for boilers and certain incinerators that it says will achieve extensive public health protections by slashing toxic air pollution, including mercury and particle pollution, while at the same time addressing feedback provided by industry and labor groups, increasing the rule’s flexibility and dramatically reducing costs. As a result, 99% of the approximately 1.5 million boilers in the U.S. are not covered or can meet the new standards by conducting periodic maintenance or regular tune-ups.
“As a result of information gathered through this review, including significant dialogue and meetings with public health groups, industry and the public, the final rule dramatically cuts the cost of implementation by individual boilers that EPA proposed in 2010,” according to EPA. EPA estimates that for every dollar spent to reduce these pollutants, the public will see $13 to $29 in health benefits, including fewer instances of asthma, heart attacks, as well as premature deaths.
The new rules set numerical emission limits for less than 1% of boilers—those that emit the majority of pollution from this sector. For these high emitting boilers and incinerators, typically operating at refineries, chemical plants and other industrial facilities, EPA is establishing more targeted emissions limits that protect public health and provide industry with practical, cost-effective options to meet the standards.
EPA has also finalized revisions to the Non-Hazardous Secondary Materials Rule to provide clarity on what types of secondary materials are considered non-waste fuels and provide greater flexibility in rule implementation. This final rule classifies a number of secondary materials as categorical non-wastes when used as a fuel and allows for operators to request that EPA identify specific materials through rulemaking as a categorical non-waste fuel.
Of most interest to composite manufacturers is the continued designation of resinated wood as a non-waste when used as a fuel, and its revised definition. EPA’s revised definition now includes additional materials in order to be more representative of the universe of resinated wood residuals that are currently used as fuels throughout the wood product manufacturing process, a change lobbied for by CPA. The definition, which now includes physical off spec materials, reads: “Resinated wood means wood products (containing binders and adhesives) produced by primary and secondary wood products manufacturing. Resinated wood includes residues from the manufacture and use of resinated wood, including materials such as board trim, sander dust, panel trim, and off-specification resinated wood products that do not meet a manufacturing quality or standard.”
