Installation of CR&R; Inc.’s biofilter, a system to help eliminate noxious smells coming from its waste transfer facility, should be completed by the end of the month, said Paul Relis, a vice president at CR&R.;

The biofilter is almost one acre in size. It uses the natural metabolic cycles of bacteria to break down the offensive odors.

Fans inside the facility blow the offending air out of the building through perforated pipes. Released air comes in contact with a layer of wood chips where bacteria and fungi grow.

The microorganisms feed on the distasteful chemicals and convert them into the harmless byproducts carbon dioxide and water.
