To support dairy, dairy-allied industry, and agency knowledge and decision-making, this paper provides an overview of the major nutrient recovery (NR) approaches now emerging or in use for recovery or removal of P, N, K, and other salts from dairy manure, particularly after anaerobic digestion (AD). Technologies, markets, and regulatory frameworks are evolving quickly and, as a result, this paper, its technology evaluations, associated performance, and cost estimates must be considered a time-sensitive snapshot of a changing industry.
