Ammonia emission capture in pig farming using Gas_Loop's circular solution

A technology solution for pig farming that captures 60% of ammonia emissions—equivalent to 2.4 kg per pig annually—using an ammonia washing machine. The system converts harmful ammonia into stable ammonium sulfate fertiliser via counter-current washing with sulfuric acid at pH 4.5, improving animal welfare, worker health, and reducing greenhouse gas emissions. Designed for farms with 10,000+ pigs, it advances from TRL 7 to TRL 9, indicating full commercial readiness. The recovered nitrogen reduces dependency on industrial fertiliser production, supporting sustainable, low-impact agriculture. Part of Horizon Europe and EIP-AGRI initiatives focused on nutrient recovery and circular farming.
