Technical Abstract: In the intensive swine production industry, practices and waste management systems often raise major environmental concerns. As a result, the industry is frequently subjected to environmental regulation to protect water resources, soils, and air quality. While conventional swine waste treatments based on anaerobic lagoons are potential sources of water, soil, and air pollution, retro-filing swine lagoon systems with solid-liquid separation reduces the environmental exposure to swine wastes contaminations. However, studies did not sufficiently report the full-scale greenhouse gas (GHGs) emission pertaining to a swine waste treatment lagoon integrated with a solid-liquid separation plant. Yet, the quantification of these GHGs emissions is critical to fully portend the benefits of solid-liquid separation plants in swine production hubs. Hence, this study uses a continuous 12-months measurements of full-scale gas emissions from two swine waste treatment systems including a conventional lagoon which collects raw swine wastes and a swine lagoon integrated with a solid-liquid separation system. Emissions of N2O, NH3, CH4 from individual lagoon were separately estimated using guidelines proposed by the Intergovernmental Panel on Climate Change (IPCC). Comparison of the GHGs emissions based on treatment scenarios are analyzed and discussed.
