“…However, for the past several decades there has been considerable commercial interest in anaerobically digested animal manures, especially dairy manure, as an organic fertilizer or as a peat moss replacement (Raviv et al, 1986;Marchaim et al, 1991;Morris and Lathwell, 2004;Lazcano et al, 2009;MacConnell and Collins, 2009;Farrell and Jones, 2010;Krucker et al, 2010;Möller and Müller, 2012). Several problems have been found with the use of these manure-based digestates, including higher bulk densities and high EC, basic pH values, lower water holding capacities and lower porosities than peat-based substrates (Corti et al, 1998).…”

“…It represents a potential possibility to decrease the environmental pollution, and at the same time provide biogas for local energy needs. In addition, in the specific case of treatment of animal wastes, the remaining stabilized slurry after digestion may be used as a fertilizer (Marchaim et al 1991;Borja et al 1998). However, the process is sensitive and prone to failure.…”

Mesophilic and thermophilic anaerobic co-digestion of abattoir wastewater and fruit and vegetable waste in anaerobic sequencing batch reactors

Anaerobic co-digestion of fruit and vegetable waste (FVW) and abattoir wastewater (AW) was investigated using anaerobic sequencing batch reactors (ASBRs). The effects of hydraulic retention time (HRT) and temperature variations on digesters performances were examined. At both 20 and 10 days biogas production for co-digestion was greater thanks to the improved balance of nutrients. The high specific gas productions for the different digestion processes were 0.56, 0.61 and 0.85 l g(-1) total volatile solids (TVS) removal for digesters treating AW, FVW and AW + FVW, respectively. At an HRT of 20 days, biogas production rates from thermophilic digesters were higher on average than from mesophilic AW, FVW and AW + FVW digestion by 28.5, 44.5 and 25%, respectively. However, at 10 days of HRT results showed a decrease of biogas production rate for AW and AW + FVW digestion processes due to the high amount of free ammonia at high organic loading rate (OLR).

“…The digested solid coffee wastes can then be used either as a fertilizer or as a growth medium in horticulture or mushroom cultivation, while the biogas produced by AMTD can serve as a source of energy (8,9). Most studies on the anaerobic digestion of coffee waste have been performed on the pulp produced during primary processing (10,11).…”

Anaerobic methanogenic thermophilic digestion (AMTD) of the solid fraction of waste from an instant coffee factory was carried out in laboratory scale digesters. Optimal conditions were established for stable fermentation by controlling loading rates, pH, volatile fatty acid concentrations, biogas production and composition. The results of the experiments indicated that steady digestion can be maintained at organic loading rates up to 8.6 g VS L -1 d -1 , at a hydraulic retention time of 20 days, with pH at 7.5-8.2. Biogas production (62% methane) reached 1.8 L L -1 d -1 . The residual slurry of the digestion process was examined as a growth medium in horticulture. Trials of fermented solids, mixed with sphagnum peat-moss in proportions of 1:1 or 3:1 and used as growth media for ornamental plants (Gypsophila, Lysimachia and Phlox), showed a promotional effect on growth in the root systems.
