Building Momentum for Soy-Based Construction Materials
What if you could build with materials that are sustainable, that reduce exposure to suspect carcinogens and reduce our reliance on petroleum? And what if those materials perform the same or better than the products they replace, cost the same or less, and even earn LEED points?
You can. In fact, contractors and consumers have been realizing these building benefits and more when they “think soy.”
LEEDing the Way to Certification
The United Soybean Board (USB) has
supported the development of
many products that have become
important components of buildings
certified by the U.S. Green Building Council
(USGBC) LEED program.
Soy-based feedstocks significantly reduce greenhouse-gas emissions and use less fossil fuel in their manufacture, which earns points in the Materials and Resources (MR) section of LEED certification for:
* Use of a rapidly renewable resource
* Avoiding chemicals of concern
* Good life-cycle-assessment (LCA) scores
Soy-based materials also score high in the Indoor Environmental Quality (IEQ) 4.1 category, which establishes thresholds for material emissions and volatile organic compound (VOC) levels. They also excel in the IEQ 4.4 category, which rewards the use of wood products that don’t have added urea-formaldehyde.
However, the advantages of using soy-based materials go even further.
Columbia Forest Products is North America’s largest manufacturer of hardwood plywood and hardwood veneer, a long-standing leader in environmental sustainability, and innovator of soy-based formaldehyde-free PureBond® technology. Columbia’s decorative veneers and plywood panels are used to build cabinets, furniture, fixtures and millwork in homes and commercial settings.
A Cure for Sick Buildings
Soy-based adhesives used in plywood are drop-in replacements for urea-formaldehyde adhesives, which emit (off-gas) formaldehyde into indoor air in buildings. Unhealthy concentrations of formaldehyde can contribute to “sick building syndrome.” The World Health Organization has indicated that urea-formaldehyde off-gassing is a known carcinogen in humans.Soy-based materials are competitive in price and are widely available through lumber suppliers and retailers.
U.S. hospitals, airports, hotels and businesses are installing Oregon-based 9Wood custom wood ceilings and wooden grill installations made with a soy-based adhesive that does not contain formaldehyde. The choice contributes to LEED certification.
Soy is also used in the production of suspended wood ceilings and walls, as well as wood tiles. These types of products provide aesthetics, sound dampening, and concealment.
Flooring installation adhesives also contain soy as a raw material component. Some of these products are one part formulations that can replace and outperform more costly epoxy, urethane, and acrylic adhesives and are easy to use, easy to clean up, and easy to install.
The Perfect Way to Green-Light Building-Code Approvals
As a renewable, low-toxicity resource that contributes to good indoor environmental quality, soy materials help meet the requirements for the International Green Construction Code (IGCC).The new code is expected to make buildings more efficient, reduce waste and have a positive impact on health, safety and community welfare.
Soy-based coatings by Sherwin-Williams
are certified as BioPreferred.
With support from USB, Sherwin-Williams researchers developed a new paint formulation that utilizes soybean oil and recycled plastic bottles. This formulation reduces VOCs by 60 percent.
The company received the 2011 Presidential Green Chemistry Award from the Environmental Protection Agency (EPA) for its new formulation. Today, Sherwin-Williams sells more than 20 million gallons of soy-based products each year. Ten of their soy-based coatings are certified under the U.S. Department of Agriculture’s BioPreferred program.
Millennium One Step™ Green Insulation Adhesive by ADCO is a VOC-free, all-weather insulation adhesive. One Step Green is manufactured with 45 percent rapidly renewal content for maximum green building credits.
Life-Cycle Benefits of Soy
Rigorous studies demonstrate valuable life-cycle contributions from using U.S. soy for non-food uses, including building-construction materials.
USB released a peer-reviewed update of the life-cycle-inventory databases for soybean production and processing. The update considered four key soy-derived feedstocks for industrial products: (1) methyl soyate, (2) soy lube base stock, (3) soy polyol and (4) soy resin. Check out the report online at www.SoyNewUses.org.
Green Building and Design Freedom
As manufacturers realize the value and benefits of using soy as a replacement for petrochemicals and carcinogens, the number of soy-based products continues to grow. Performance advantages of soy-based products, combined with enhanced availability, make it easier than ever to design more environmentally friendly buildings.
Soy-based materials create strong, beneficial construction plastics. Soy polyols can be used for polyurethane and as a base material for thermoset plastics.
Innergy® Rigid Thermal Reinforcements by Deceuninck and Bayer MaterialScience, are advanced fiberglass reinforced soy-based resin inserts, designed to slide easily into window and door frame chambers for greater support and insulation.
Carpet and artificial turf backing developed with USB support by Universal Textile Technologies uses soy feedstock to replace styrene butadiene and polyvinyl chloride (PVC). This reduces VOC production and the total flammability of the flooring.
Spray-foam insulation based on soy polyurethane made by several manufacturers delivers a high R-value and a good barrier for air and moisture. The product is typically applied as a system, sprayed into enclosures. It can also be sprayed into floor and roof assemblies.
Soy-based foam insulation delivers a high R-value for new construction or renovation.
For furnishings, built-in seating and other uses, flexible soy foam enjoys a growing market in the architectural and construction industries. It is already used extensively in the automotive and furniture industries.
Many lubricants and solvents used in building mechanical systems can be made with soy.
Soy has also been introduced as a base material for producing an alternative to asphalt cement, which constitutes about 28 percent of the materials for roof shingles. Some manufacturers and contractors are recycling used shingles, using solvents that are about 25 percent soy based. This is considered a valuable material-reuse strategy, as well as a promising way to cut project costs since primary asphalt prices have quadrupled in the last decade alone.
An abundant, renewable resource that is healthier for building occupants and versatile and durable for construction uses? The simple soybean sounds like a winning ingredient – ripe for growth in the world of building design and construction.
