One little-known benefit of the coil coating process is its ability to apply coatings to metal with little harmful impact on the environment - making the VOCs all but disappear.

With coil coating, solvent-based paints and coatings can be applied with minimal VOC emissions, says Cleveland-based National Coil Coating Association. Coil coating is an efficient “closed loop” process, meaning that harmful solvents and gas are consumed in the combustion process and byproducts are incinerated or oxidized prior to release into the environment. In effect, the coil coating curing ovens burn the harmful VOCs, using them as fuel, saving energy and eliminating pollutants. According to NCCA, coil coating achieves at least a 98 percent rate for capture and destruction efficiency, eliminating toxic pollutants that would otherwise be released into the air.

The coil coating industry is subject to the highest EPA standards and meets and exceeds these standards even as they become more stringent each year, NCCA notes. The end products are also green: coil coated metal is fully recyclable, and coil coated products are often made of recycled content.
