In this present study, the eff ectiveness of mixing and filtration methods using zinc oxide (ZnO) nanoparticles to control hydrogen sulphide (H2S), ammonia (NH3) and odour emissions from swine facilities were evaluated under conditions that represent normal swine production. The addition of ZnO nanoparticles into the manure achieved more than 95% reduction in H2S level; no significant effect on NH3 and odour concentrations was observed.  ZnO nanoparticles were persistent in maintaining low H2S level up to 15 days after treatment application. On the other hand, the ventilation air recirculation system with ZnO filter achieved significant reduction in both H2S and NH3 concentrations at the animal- and human-occupied zones.
