Dark Fermentation of Jam Washing Water Coupled with Fruit and Vegetable Wastes and Upgrading to Two-Stage Anaerobic Digestion

Short Introductive summary

In recent years, biomasses are raising as alternatives to fossil fuels to produce fuels and chemicals due to their renewability and carbon neutrality. Biomass wastes figure as promising feedstocks for biological processes as dark fermentation (DF) which is employed to produce biohydrogen (bioH2). This work illustrates the results from a dark fermentation of fruit and vegetable residues from household waste coupled with an innovative substrate which is the washing water employed to clean jam production equipment. Biogas produced was analyzed in terms of volume and composition to assess if these substrates are suitable for bioH2 production. Further laboratory activities are underway to perform a two stage anaerobic digestion (TSAD) on jam washing water and fruit and vegetable wastes to evaluate H2 and CH4 production on this innovative substrate which from waste is valorised as raw material in accordance with circular economy principles.
