A life cycle analysiscompares combustion of poultry litter to produce electricity to othervalorisation routes: co-burning in a biomass electricity plant,co-digestion, direct application to farmland, and various compostingoptions. The overall conclusion is that combustion for electricity isthe best environmental route if phosphorus and potassium are recycled asash is sold as fertiliser (not the case for biomass co-burning). Directapplication of poultry litter and application of digestate result inparticulate emissions. Transport of the litter and/or resulting productsis also a significant factor. The LCA was made by CE Delft for BMCMoerdijk, a plant co-owned by 600 poultry farmers (DEP Cooperative)burning 430 000 t/y of poultry litter in the Netherlands since 2008,producing 285 GWh of electricity and 60 000 t/y of ash.
