In France, digestates from anaerobic digestion plants have to pass through homologation process or reach certain specific standards to be commercialized. In this study, valorisation processes regarding the production of added-value products from urban digestates are being explored. Humic Acids (HA) extracted from upcycled organic products such as composts have been demonstrated to improve soil fertility [1] and industrial applications have been proven more recently [2]. However, very few studies addressed HA-recovery from digestates [3]. Preliminary tests presented in this study were carried out in order to assess the feasibility of recovering HA from such urban digestates. The samples were a Food Waste/Cardboard digestate (FW/CB-D) from a pilot reactor and an Organic Fraction of Municipal Solid Waste digestate (OFMSW-D) from a full-scale plant. HA-extraction was tested on raw digestates and on its solid fractions after laboratory centrifugation. A practical approach for HA extraction was performed, adapted from [4]: NaOH 0.1 M was added until pH 12 was reached. The solution was stirred for 24h. After the alkaline extraction was performed, the digestate was centrifuged. The supernatant was filtered at 0.45 μm and acidified at different pH (1, 2, 3, 5 and 7). This solution was centrifuged to isolate the insoluble fraction containing HA. The recovered HA were redissolved for Fluorescence 3D analysis. Another acidification at pH 3 was performed where the precipitate was washed several times with distilled water and freeze-dried for Mid-Infrared analysis and calculation of recovering yields. Recovered HA were compared to HA isolated from a leonardite commercial solution and to references from the International Humic Substances Society (IHSS). Freeze-dried HA yields were low: from 3 to 4% (volatile solids:volatile solids) and 1 to 2%, for raw mass of FW/CB-D and OFMSW-D respectively. HA extracted from FW/CBD were observed to be similar to a river sediment reference from the International Humic Substances Society. The HA from OFMSW was closer to the HA isolated from the leonardite solution, but it presented more proteins in the 3D fluorescence spectra. When HAs were extracted from the solid fraction of digestates, HA extraction yields and spectra were almost unchanged. The pH for acidification played an important role in HA isolation. pH 1, 2 and 3 were observed to perform similarly (quality and quantity) but pH 5 and 7 resulted in less extraction of HA and poorer quality. Industrial feasibility of HA-like extraction from digestate would rely on extraction yields, product quality and residual matter management options. Experiments will be carried out in order to further evaluate the quality of the products regarding biodegradability and impact on root growth
