In Canada, the piggery industry is an essential part of the agricultural sector, but the main waste product of this industry, swine slurry, is particularly harmful to the environment. The anaerobic storage conditions and the excessive use of slurry for agricultural fertilization contribute, respectively, to the emission of greenhouse gases and to aquatic pollution. This paper provides a review of these environmental concerns and of the existing mitigation technologies. Water pollution from swine slurry is associated with the nutrients it contains, such as nitrogen and phosphorous, while the main greenhouse gases produced by the piggery industry are methane and nitrous oxide. Available technologies can valorize the slurry through agricultural fertilization, reduce greenhouse gas emissions, by limiting nutrient availability for example, or treat the effluents using solid-liquid separation, flaring or biological processes. Specific attention is paid to biofiltration due to its potential to simultaneously treat these two types of pollution.

Au Canada, l’industrie porcine occupe une place de choix dans le secteur agroalimentaire, mais le lisier de porc, sous-produit de cette industrie, est particulièrement nocif pour l’environnement. Les conditions d’entreposage et l’épandage excessif du lisier contribuent respectivement aux émissions de gaz à effet de serre et à la pollution aquatique. Cet article présente une revue de ces problèmes environnementaux et des technologies disponibles pour limiter leur impact. La pollution de l’eau causée par le lisier de porc est associée aux nutriments qu’il contient, l’azote et le phosphore notamment, tandis que les principaux gaz à effet de serre sont le méthane et l’oxyde nitreux. Les technologies existantes peuvent valoriser le lisier par la fertilisation agricole, réduire l’émission des gaz à effet de serre ou traiter les effluents par la séparation solide-liquide, des torchères ou des procédés biologiques. Une attention particulière a été portée à la biofiltration pour son potentiel à traiter simultanément ces deux types de pollution.
