CHATTANOOGA, Tenn. (AP) -- Volkswagen executives say the paint shop at their new Chattanooga assembly plant is uniquely green.
Working inside the plant's 2.5 million square feet of glistening floors, bright lights and colorful robots to build a new 2012 Passat, paint department manager Lothar Grensemann describes environmentally friendly paint technologies, including some he says are unique.
When painting each car, the paint shop uses dry crushed limestone to pre-coat filters and catch wet paint overspray. That eliminates disposal of paint sludge.
A paint specialist who works with other automakers, Optimum Polymer Technologies Inc. CEO David Ghodoussi of Memphis, says the VW plant's EcoDry Scrubber process is a "major improvement" over wet paint separation.
