Unique quantum properties are exhibited in nanoparticles as they have at least one dimension in the 1-100 nanometer scale. Nanoparticles have been of use for environmental pollutant treatment and remediation. They are non-toxic and benign environmentally while flexible in deployment and highly reactive due to their large surface area, small size, crystal shape and lattice order. Various types of nanoparticles were evaluated for their effectiveness in controlling swine manure emissions. The deployment techniques used were spraying into the headspace above the manure slurry, mixing them with the slurry and acting as a filtering medium for the manure gases. Twelve types of nanoparticles were used with zinc oxide decreasing the concentration of hydrogen sulphide by 99% in the filtration and mixing methods. Also 86% ammonia reduction and 79% odour concentration reductions were noted in these methods. The only greenhouse gas that was reduced (by 55%) was methane through zinc oxide in the mixing method.
