Technical Abstract: Land disposal of poultry litter is an environmental concern in regions with intense poultry production because there is not enough land for crop utilization of its nutrients, especially phosphorus (P). This situation promotes soil P surplus and potential pollution of water resources. Although poultry litter can be moved off the farm and traded as fertilizer, its transportation becomes less economical with increasing distances from the farm. Thus, new litter use alternatives are needed to prevent pollution of surface water by P litter application. Our objective was to summarize established and emerging alternative technologies that could facilitate handling, concentration, and transporting of litter P. These alternative technologies can reduce poultry litter volume and increase P content in litter byproducts by sieving, densification, biological, thermochemical, and chemical processes. Their adoption may encourage new opportunities to produce bio-energy, fertilizer, and other valuable P byproducts from poultry litter while promoting sustainable poultry production.
