Odor reduction

The Maris Technological Center has recently designed and tested a new process for the reduction of odors within polymers having post-consumer origins.

The materials that can be processed can be the most varied; the table shows two examples of HDPE coming from bottles for detergents and tanks for fuel. In order to extract effectively the odor contribution, it is necessary to equip the extruder with two different degassing points.

Besides the addition of particular additives for odor reduction, Maris has devised a special stripping system, thanks to the injection of water along the odor-reduction process.

Thanks to this innovative process it is possible to obtain a material with odor values of a few ppm and therefore to be able to give a new life to these materials.
