In addition, digestate\ngenerated alongside biogas can be used as a source of fertilizer since the process preserves\nfed nutrients. Co-dry fermentation of dried chicken manure and fresh kitchen waste was\nstudied in an anaerobic digestion process to recover the energy and nutrients in the studied\nsubstrates. At first, methane potential of the two waste fractions and their mixtures was\ndetermined in biological methane potential (BMP) \u2013tests at 35 \u00b0C. The biogas production\nof the waste mixture was studied in a semi-continuous plug-flow reactor at 35 \u00b0C. Later,\nthe fertilizer potential of generated digestate was evaluated based on the nitrogen and\nphosphorus concentrations.\n\nBMP results show that the highest methane production of 398.5 mlCH4/g volatile solids\n(VS) added was obtained when the waste mixture consisted of 10 % chicken manure + 90\n% kitchen waste on VS basis. Increase in chicken manure in the waste mixture decreased\nthe methane production (340.8 \u2013 367.7 mlCH4/gVS) due to low biodegradability of\nchicken manure. BMP\u2019s of chicken manure and kitchen waste produced 301.1 and 411.1\nml CH4/gVS, respectively. In the semi-continuous dry fermentation process, methane\nproduction was 388.2 mlCH4/gVS at 3 gVS/l/d organic loading rate and no process\ninhibition was observed. However, steady-state conditions were not achieved and further\nlong-term semi-continuous reactor studies are needed to confirm these results. Based on\nthe results, co-digestion of dried chicken manure and kitchen waste by dry fermentation is\nfeasible and productive but nitrogen feed should be low in order to prevent inhibition.\n\nChemical analyses showed that nitrogen (N) and phosphorus (P) concentrations in the\ndigestate were 4 g/l and 0.3 g/l respectively and were comparable to that of commercial\nbio-fertilizers (11 \u2013 14:1 N:P). The total N:P ratio in the digestate was high (13:1) and thus\nmay limit its use on soils with high N content.
