Özet
This study evaluates the hydrogen-production potential of heterogeneous airport-derived waste fractions through separate thermochemical gasification and biochemical dark fermentation routes. Aircraft-derived wastes, food residues, and de-icing wastewater were assessed as feedstocks. Gasification was conducted in a fixed-bed updraft reactor at 700–1000 °C using air and oxygen, and hydrogen content reached 61% (v/v) at 1000 °C under oxygen. Dark fermentation was performed at 35 °C, with optimal F/M and initial pH ranges of 7–8 g glucose/g VSS and 7.5–8.0, respectively. Co-substrate addition increased the apparent hydrogen yield from 2.6 to 5.3 mol H2/mol glucose compared with the mono-substrate system. These yields were calculated using the glucose-equivalent amount derived from the net COD decrease. Overall, biodegradable organic fractions showed potential for dark fermentation, whereas structurally complex solid fractions were more suitable for thermochemical conversion. The findings provide a preliminary waste-specific assessment of separate hydrogen-production routes for heterogeneous airport waste streams.
