Adhesives & “Green”

Seeing the forest through the trees

(Download a printable .pdf version of this article here.)

Green is the practice of increasing the efficiency with which companies use resources — energy, water, and materials — while reducing impacts on human health and the environment.

Low-impact building materials (such as adhesives) are used wherever feasible: for example, insulation may be made from low VOC (volatile organic compound)-emitting materials such as recycled denim or cellulose insulation, rather than the building insulation materials that may contain carcinogenic or toxic materials such as formaldehyde. To discourage insect damage, these alternate insulation materials may be treated with boric acid. Organic or milk-based paints may be used, however, a common fallacy is that "green" materials are always better for the health of occupants or the environment. Many harmful substances (including formaldehyde, arsenic, and asbestos) are naturally occurring and are not without their histories of use with the best of intentions. A study of emissions from materials by the State of California has shown that there are some green materials that have substantial emissions whereas some more "traditional" materials actually were lower emitters. Thus, the subject of emissions must be carefully investigated before concluding that natural materials are always the healthiest alternatives for occupants and for the Earth.

Volatile organic compounds (VOC) can be found in any indoor environment coming from a variety of different sources. VOC’s have a high vapor pressure and low water solubility and are suspected of causing sick building syndrome type symptoms. This is because many VOC’s have been known to cause sensory irritation and central nervous system symptoms characteristic to sick building syndrome, indoor concentrations of VOC’s are higher than in the outdoor atmosphere, and when there are many VOC’s present, they can cause additive and multiplicative effects. Green products are usually considered to contain less VOC’s and be better for human and environmental health.

Effective green initiatives can lead to 1) reduced operating costs by increasing productivity and using less energy and water, and by avoiding costly fines, 2) improved public and occupant health due to improved indoor air quality, and 3) reduced environmental impacts by, for example, lessening storm water runoff and pollution.

When evaluating an adhesive product as “green” it’s important to consider it within the following framework:

Regulatory Impact –

Environmental regulations, limitations, and specifications are becoming increasingly prevalent.  They emanate from numerous areas.  These include; international bodies, federal, state and local governments and private concerns such as architects, NGOs, and for-profit testing agencies.  Currently, CARB (California Air Resources Board) regulations and LEED (Leadership in Energy and Environmental Design) certification requirements are at the forefront of regulatory issues involving adhesives.  There is considerable confusion regarding both of these issues but, basically, both limit the amount of VOCs (Volatile Organic Compounds) and formaldehyde permitted in an adhesive.  Additional agencies such as OSHA, DEP, and DOT impose limits on certain chemical elements in the name of “Green” as well but these have yet to become as pervasive as those mentioned earlier.  Further information on both CARB and LEED is contained in the resources section at the end of this paper.

Environmental Impact –

There is no doubt that adhesives (as well as all chemicals) impact the environment.  When evaluating adhesives it’s necessary to consider the impact across the entire environmental spectrum.  This includes upstream aspects such as where the adhesive is manufactured and where the raw materials for the adhesive are sourced as well as how it is manufactured and any wastes that might be created during its production.  Downstream considerations are important as well; at the end of a product’s life will there be an environmental impact due to the adhesive used?  It is also necessary to consider the environmental impact at the plant level.  Are there health ramifications when the adhesive is in a “wet” state?  Does it require mixing?  Are there other hazards such as flammability, waste generation, toxicity, and airborne issues that should be addressed before the adhesive is used in manufacturing?  Will it affect storm water run-off?  Are there specific clean-up issues?  These are all legitimate issues that are part of “green” and adhesives.

Business Impact –

At the end of the day, green adhesive initiatives must be measured in terms of impact on business.  The costs (and the benefits) are myriad and often subtle.  For example: a flammable contact cement may appear to have a lower cost per gallon than its waterbased counterpart but when a business takes into account the additional costs of transportation, insurance, specialized handling equipment and employee health the “green” alternative comes out ahead.  On the flip side, urea formaldehyde resin may appear to be at odds with any “green” initiative but if one examines the whole picture including product cost and performance as well as environmental impact they find that UF resin is often the best of all possible choices in manufacturing.  It’s also necessary to take “risk” into account.  Using toxic, flammable or other non-green adhesives presents the user with considerable risk.  This comes in many forms including fines and penalties from regulatory agencies, increased fire hazards and the risk of damage to a company’s reputation.  Finally, embracing “green” adhesives opens the door to additional business and increased margins as a result of added value to the products being manufactured but it’s necessary to make an informed decision rather than jumping on the band wagon because it seems like a good thing to do.

“Green” is not a fad.  Increasingly it has become a way of life for companies across all business spectrums.  Adhesives play a small role in a much bigger picture but by understanding their role we can understand “green” within a much larger context.
