WILMINGTON, Mass., April 11, 2012 /PRNewswire/ -- In its ongoing commitment to environmental sustainability, UniFirst Corporation, a national leader in the uniform rental industry, decided in 2011 to exclusively utilize only the latest generation "green" (environmentally-friendly) cleaning detergents in all its industrial laundry operations throughout the U.S. and Canada.

Use of the environmentally friendly detergents are proving to be a win-win scenario for all concerned, since their formulation continues to allow UniFirst to provide hygienically clean, image-enhancing work apparel to heavy- and low-soiling occupations such as auto repair, corporate management, healthcare services, oil field drilling, and more—but with virtually no environmental impact. "We're committed to using only sustainable chemistries in all of our laundering facilities and will continue to pursue 'greener' practices wherever possible in our operations," said UniFirst President and CEO Ron Croatti. "Our ongoing goal is to be an environmental steward in each of the communities we serve throughout North America." The "green" detergents used by UniFirst are concentrated and, as such, require less water and energy use during laundering cycles, thereby further conserving environmental resources. Furthermore, unlike home detergents that can sacrifice cleanliness for "fresh smelling" clothing, the detergents used by UniFirst are specially formulated with a higher concentration of active cleaning ingredients for maximum soil and stain removal and minimal wear on fabrics. UniFirst's concerted conservational efforts in the laundering and processing of work uniforms dates to 1997 when it joined the Laundry Environment Stewardship Program (Laundry ESP®), an industry initiative that resulted in 12.5 percent reductions in water use and 11.8 percent reductions in energy use.
