The parts of your liquid fraction may be selectively separated by bipolar electrodialysis [133]. This enables for your elimination of opportunity large steel contamination from the fertilizer product. Recovery of phosphate from poultry litter may be carried out in two levels: acid and carbon dioxide treatment method and precipitation in an alkaline surroundings with simultaneous aeration. With this method, over 70% of phosphorus is often recovered in a short time (less than one hour)*** [134]. The report by Staro et al. (2016) evaluated prospective waste from the meat field, such as feathers, meat and bones, and poultry litter, to get fertilizer additives rich in macronutrients.
