Recovery of energy and nutrients from urban and industrial residues
Novel Prototype for Manure Stabilization and Mitigation of Greenhouse Gas Emissions
Short Introductive summary
Agriculture is regarded as a source of 30 % of global anthropogenic emissions. A novel technology, aligning with current regulations of covering slurry stores, has been developed for processing manure directly obtained from the stables of beef cattle, dairy cows, and fattening pigs. The aeration in the closed environment of the stabilization chamber allowed the composting process and the enhanced microbial respiration during the dehydration of the soil organic amendment, down to 50 % moisture, which was assisted by the removal of ammonia and carbon dioxide in the brine of calcium chloride that is generated in the condensation chamber, as described in previous investigations. For this investigation, the novel prototype was initially charged with raw cattle slurry and samples of 1.5 kg were taken during the next 5 days of operation until, to assess the stabilization process in terms of maturity of the organic manure (i.e., moisture content, rotte grade, phytotoxicity, inorganic carbon content) and availability of the nutrients (nitrogen and phosphorus).
