As fast-food oils continue to be recycled for car and machinery biodiesel fuels, a new application has been prompted by company United Environment & Energy: roof-shingle coating.
Funded in part by the U.S. Department of Energy, fast food waste oil forms into a coated plastic polymer when applied to exterior surfaces. When paired with the much-heralded white roof solution supported by Energy Secretary Steven Chu, the potential for soaking sunlight, saving energy and cooling buildings is endless.
Ariel Schwartz of Fast Company explains:
“Like white paint, the polymer reflects sunlight in warm weather, but it has the added bonus of absorbing heat in cold weather. In testing, the polymer showed a decreased roof temperatures between 50% and 80% in hot weather compared to normal asphalt shingles along with a 80% increase in temperature in cold weather. It has all the benefits of white paint, in other words, with none of the drawbacks.”
