GPCE designs and constructs biofilters with packing material, for the removal of odorous compounds from gases.

The organic packing material depends on the application's requirements.  For the appropriate and efficient operation of the biofilters, the humidification of the inlet gases and also the wetting of the biofilter's material surface are crucial. 

GPCE cooperates with foreign suppliers for the biofilter material and undertakes the design, construction and commissioning of biofilters.

Biofilters are used effectively mainly in Odor Removal plants in Solid Waste Treatment plants, but also in factories producing gases with toluene (f.e. Dyes).
