Sure, it saves the rest of the world from formaldedhyde poisoning, but it paints rooms with certain death to those few of us out there allergic to nuts!

INSIDE JoongAng Daily: "Korean researchers have developed a cheap, eco-friendly paint from cashew shells that does not use formaldehyde, a state-run chemical technology institute said yesterday. The team, led by Song Bong-geun of the Korea Research Institute of Chemical Technology, said cashew shells and biocatalysts such as peroxidase and hydrogen peroxides were used in manufacturing the new paint. Ordinary paint is usually manufactured by mixing phenol and formaldehyde. Such substances, which have been blamed for causing cancer in humans, are also the main cause of the so-called sick house syndrome. “The new paint is not only ecologically friendly, but has excellent chemical and heat resistant qualities,” Song said, adding that the new paint protects the material it covers and dries much faster than most formaldehyde-based paints. Song said that after two hours the paint does not smear when touched and maintains hardness, surpassing ordinary paint throughout the drying process. It is highly transparent, making it easy to apply various colors. In addition to containing no harmful substances, the new paint can be made in room temperatures of 18 degrees Celsius versus 100 degrees for some conventional paints. This difference translates into considerable savings in energy and manufacturing costs."
