With Agrifarm’s patented air exchange technology you have the opportunity to increase your production while at the same time improving environment, animal welfare and your earnings.

With the development of the air exchange technology called Environment Defender we received the EU Environmental Award on March 23rd 2012. Furthermore the technology was launched as a three star novelty at the agricultural fair Agromek in 2009, where we also received the Agromek Award for our technology.

New cutting - edge environmental technology

We have developed and patented a completely new and cutting – edge environmental technology, Environment Defender, and in this system a controlled air stream is flowing across the manure in the slurry channels, thereby capturing ammonia emissions, odor gasses such as CO2, methane and laughing gas/nitrous oxide. The result is less strain on the animals and the immediate environment compared to traditional housing systems.

With Environment Defender up to 90% of the ammonia and 50% of the odor compounds are collected. This means that the air quality in the stable is markedly better than in normal housing systems, and this is achieved without otherwise interfering with the natural ventilation in the housing system.  

With the system you get:

  • Reduced emissions of both ammonia and odor compounds
  • Reduced negative impact of the animals and the immediate environment
  • A good housing climate all year round
  • Improved udder and claw health
  • Improved animal welfare

This is how it works

With the air exchange system a controlled air stream is flowing above the manure across the slurry channels. The air stream captures the majority of the gaseous ammonia and odor compounds, which would otherwise have evaporated into the immediate environment and thereafter into the outside environment. The system can be retrofitted to any air cleaning system. The technology is suitable if you want to deliver your slurry to a biogas plant.
