Hofstetter - Landfill Odor Reduction Systems
The odor coming from landfill sites can be managed using different techniques that either aim at covering the waste or at neutralizing smells in the air. With Hofstetter Gastechnik, any solution design starts with a careful determination of the odor source.
Our odor control systems use reagents that neutralize-rather than mask the landfill smells. Depending on the specific site, those reagents are distributed through air cannons, sprinkler networks or foams.
Our reagents are composed of natural and synthetic essential oils, made up of mixtures of Aldehydes and Ketones. Through chemical reactions, those mixtures neutralize foul-smelling gases such as ammonia, amines, hydrogen sulphide and mercaptans.
The efficiency of our solution has been tested by numerous external laboratories and universities such as the SUEZ Group, the University of Rennes, and Veolia.
Our products are non-toxic and regularly tested for biodegradability, eye, skin and lung toxicity, phytotoxicity and ecotoxicity. All substances are registeredon the IFRA list (International Fragrance Association).
