Experimental study of precursor greenhouse gas reduction in biofilter systems using nanomaterials

Benzene, toluene, ethylbenzene, ethylbenzene and xylene (BTEX), emitted in animal farms, were measured in this study for 84 days. To reduce precursor VOC emission, poultry litter were covered with nanomaterial (graphene oxide, single-walled carbon nanotubes, multi-walled carbon, activated carbon, and graphite) as daily cover. The adsorbent material performances between the cabinets were compared statistically using Mann-Whitney U, Kruskal Wallis H and Wilcoxon tests. It was concluded that a decrease in pollutant emission was observed when adding carbon nanotubes. Different materials did not cause a difference in pollutant release between benzene, toluene, xylene and ethylbenzene.
