A number of techniques are available to reduce the odor concentration in exhaust gases collected during composting including absorption, condensation, adsorption, oxidation by thermal, chemical or biological means, and use of masking and neutralizing chemicals.
Biofiltration is an classic popular air pollution control technology that uses a biologically active, solid media bed to absorb/adsorb compounds from the air stream and retain them for their subsequent biological oxidation.
