AB This Ph.D. Thesis is a contribution framed in the area of air quality in the agro-livestock sector. The research contribution focuses on the optimization of a gas-permeable membrane (GPM) technology with applications in the reduction of ammonia emissions from livestock housing or waste management processes such as composting.Firstly, the process parameters have been optimized at laboratory level to favour ammonia capture through the membranes. Subsequently, at farm scale, the best conditions have been selected and applied in a pilot plant to recover the ammonia emitted to the atmosphere by excreta, both in the livestock house atmosphere and in manure composting processes.GPM technology has proven to be a viable alternative to other technologies such as biofilters, trickling filters, and stripping systems for capturing ammonia emissions from livestock buildings. It has a high N recovery efficiency (up to 98%), comparable to or higher than those of other technologies, with minimal energy and operating costs, with membrane maintenance being the main limiting factor at present.The GPM technology developed is a promising alternative to address the challenge of reducing ammonia emissions to the atmosphere from the agro-livestock sector, contributing to the fulfillment of national commitments to reduce emissions collected in Art. 4 of the European Directive 2016/2284/EU on the environment.
