Odor Control in the Waste and Recycling Industry

Odors, sulfur compounds, ammonia, or organic emissions—the processing of organic waste and animal by-products generates significant odor and pollutant emissions.

With oxytec systems, these emissions can be treated in a targeted and efficient manner—for better air quality, improved working conditions, and fewer complaints from residents.

Effectively neutralize ammonia, H₂S, and barn odors

Whether it’s the storage of liquid manure, the processing of solid manure, or the drying of chicken droppings—strong-smelling and, in some cases, hazardous gases are produced. Ammonia (NH₃), dimethyl sulfide (CH₃₂S), and hydrogen sulfide (H₂S) are particularly harmful to humans, animals, and the environment.

Complaints from residents, stricter environmental regulations, and health risks make targeted exhaust air purification a necessity—or an opportunity.

Common problems in practice

In many processes, targeted air pollution control is not only a requirement but also a competitive advantage:

  • Slurry & Manure (Cow, Pig, Chicken)

  • Anaerobic digestion of food and kitchen waste

  • Composting & coffee grounds recycling

  • Blood meal production & heparin manufacturing

  • Animal carcass disposal & sanitization

  • Collection points & transfer stations for organic waste

  • On-site biomass drying

Exhaust air purification in biogas plants – odors, gases, and emissions
Exhaust air purification for manure and agricultural by-products – controlling odors, protecting processes
Exhaust air purification in coffee grounds recycling – preventing odors, optimizing processes
Exhaust air purification in sewage sludge drying – stopping pollutants, controlling odors
Exhaust air purification during the fermentation of food waste – safely remove odors, ammonia & germs
Exhaust air purification in rendering plants and rendering plants – reliably controlling odors and emissions
Exhaust air purification for cow manure, pig manure and chicken manure – effectively combating odor, ammonia and germs
Exhaust air purification in the sanitization of organic waste – protecting health and the environment
