Prediction of organic matter accessibility and complexity in anaerobic digestates

Food waste to new food: Risk assessment and microbial community analysis of anaerobic digestate as a nutrient source in hydroponic production of vegetables

“…This is supported by the findings in the accelerated microbial activity assessments in Section 3.1 where growth was only obtained after supplementation of BHI. This is also in line with a recent study by Fernández-Domínguez et al (2021) who reported that non-biodegradable compounds increased largely after anaerobic digestion. Besides the lack of available nutrients, the chemical composition of the biofertilizer could exert an additional inhibitory effect on the establishment and survival of the food-borne pathogens.…”

Random Forests for Soil Carbon Storage Prediction Potential of Organic Residues Based on Organic Matter Characterization

“…Indeed, solid digestates seem to contain more stable OM than liquid and raw digestates. C_bio values of digestates are weaker than AD feedstock, which is also consistent with the OM stabilization provided by AD (Fernández-Domínguez et al, 2021). However, the…”

“…4 to 7) from SPOM to SEOM as well as fluorescence zones 4 and 5 from PEOM. Finally, the third cluster is an intermediary with a main part of raw digestate (54%) coming from several origins (cow manure in co-digestion, territorial and municipal wastes) highlighting the high variability of OM, related to the high variability of AD feedstock origin as shown by (Guilayn et al, 2019) and(Fernández-Domínguez et al, 2021).…”

“…Despite some highlighted trends, the a priori clustering depending on the type of transformed products is not sufficient to classify the samples considering the ISBAMO variables. The feedstock origin plays also a significant role as shown by Fernández-Domínguez et al (2021).…”

Assessing Digestate at Different Stabilization Stages: Application of Thermal Analysis and FTIR Spectroscopy

“…Spectroscopic analysis aids in understanding changes in organic material suffered during microbial degradation. This technique has provided useful information when evaluating the composting of lignocellulosic material and wastes [56][57][58] and studying the digestion process of different substrates [8,[59][60][61]. Figure 6 shows the spectra obtained from the feed and digested samples.…”
