ToxicTrailers.com was launched after Hurricane Katrina in 2005 when the government spent more than $2 billion on FEMA trailers with high levels of formaldehyde that sickened thousands of people. The FEMA trailer tragedy exposed what is a widespread problem in RVs, mobile homes, modular buildings and even conventional buildings that use pressed wood products. Unfortunately, as we approach the tenth anniversary of Katrina, formaldehyde regulations are not being enforced in the U.S., and people's health is at risk. If you are having burning eyes, congestion, sore throat, coughing, breathing difficulties, frequent sinus infections or rashes, and difficulties concentrating, you may have a formaldehyde problem.

Starch could replace formaldehyde in wood products
As we can see by the number of manufactured houses and even conventional houses that test high for formaldehyde, what is needed isn't reducing the formaldehyde content of product but eliminating it in favor of a binder that is non toxic to humans. The Green Chemistry Journal in an article "Starch as a Replacement for Urea-Formaldehyde in Medium Density Fibreboard" published recently says: Medium density fibreboard (MDF) is a ubiquitous product formed from wood flour and a formaldehyde-based resin. The use of the latter component causes some health and environmental concerns and its use is restricted. The current study shows that thermoplastic starch can be used in place of the thermoset resin to produce materials of similar mechanical strength but with clear environmental benefits. All of the components are compostable and the resin being a thermoplastic allows the potential for remoulding and recycling which has clear environmental impact benefits.
