Abstract:
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-1d-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. © Publications Division, Selper Ltd. 1993.
