Table 5. The application and advantages of solid and liquid fraction of digestate.

Source of digestate Fraction Application and advantages Reference
brown macroalgae solid phenol production (154)
cattle slurry mixed with energy crops (maize silage and triticale silage) liquid biofertilizer (155)
food waste liquid production of biochar by pyrolysis (156)
maize silage and chicken manure liquid plant fertilizer and soil conditioner (157)
mixture of cow manure, cheese whey, poultry manure, olive pomace and corn silage liquid production of an enzyme (exo- and endoglucanase, xylanase, β-glycosidase and laccase) (158)
mixture of manure, slurry, corn silage and sugar beet pulp solid production of pellets and briquettes (159)
mixture of pig slurry, olive pomace, maize silage, sorghum silage and onion scraps solid bio-oil production (150)
mixture of urban secondary effluent wastewater and digestate liquid growth and selection of microalgae (Chlorella and Stigeoclonium) and cyanobacteria (Oscillatoria sp., Aphanocapsa sp. and Chroococcus sp.) (160)
municipal organic waste solid organic supplement (161)
pig slurry liquid recycled as a solvent to dilute the raw material (silage maize) going into the system (2)
sewage sludge and source-segregated biodegradable waste liquid nitrogen removal of old landfill leachate (162)
swine manure and maize liquid significant reduction of the toxicity, high removal efficiency of ammonia, total nitrogen and phosphate (163)
wood chips liquid improved composting and digestate stability, decreased NH3 emission but multiplied N2O emission (153)
