Two Chattanooga companies behind a pair of green, energy-saving products were rewarded for their efforts today.
Astec Inc. captured the Kruesi Award for Innovation on Wednesday for developing an asphalt cement without the use of expensive or caustic additives or systems.
Also, Enerfit received the Early Innovator Award for its retrofitting of commercial air-conditioning units which saves energy and extends the life of the system.
About 700 people turned out for the Chattanooga Area Chamber of Commerce’s Spirit of Innovation event.
Ben Brock, president of the Astec Industries subsidiary, said its “warm-mix” asphalt cement provides a 14 percent cut in fuel usage.
