“…The rates and extent of bio-degradation are crucial in anaerobic fermentation of agricultural residues, which in turn depend on lignocellulose contents and properties [14]. Higher cell contents (protein, carbohydrates, and fats) tend to ferment easily and result in higher methane production [15].…”

Biogas Potential of Coffee Processing Waste in Ethiopia

Primary coffee processing is performed following the dry method or wet method. The dry method generates husk as a by-product, while the wet method generates pulp, parchment, mucilage, and waste water. In this study, characterization, as well as the potential of husk, pulp, parchment, and mucilage for methane production were examined in biochemical methane potential assays performed at 37 • C. Pulp, husk, and mucilage had similar cellulose contents (32%). The lignin contents in pulp and husk were 15.5% and 17.5%, respectively. Mucilage had the lowest hemicellulose (0.8%) and lignin (5%) contents. The parchment showed substantially higher lignin (32%) and neutral detergent fiber (96%) contents. The mean specific methane yields from husk, pulp, parchment, and mucilage were 159.4 ± 1.8, 244.7 ± 6.4, 31.1 ± 2.0, and 294.5 ± 9.6 L kg −1 VS, respectively. The anaerobic performance of parchment was very low, and therefore was found not to be suitable for anaerobic fermentation. It was estimated that, in Ethiopia, anaerobic digestion of husk, pulp, and mucilage could generate as much as 68 × 10 6 m 3 methane per year, which could be converted to 238,000 MWh of electricity and 273,000 MWh of thermal energy in combined heat and power units. Coffee processing facilities can utilize both electricity and thermal energy for their own productive purposes.

“…Typically, untreated lignocellulosic material is very difficult to degrade and thus hydrolysis of this material is considered the rate limiting step in the anaerobic digestion process [9,28]. However, the production of VFAs in the current pilot-scale digester peaked very quickly within the first two weeks of the digestion cycle followed by peak gas production on Day 22.…”

A novel co-digestion approach was evaluated to determine if agricultural and industrial waste residues could efficiently degrade straw without pretreatment. Untreated rice straw was co-digested with pig wastewater and anaerobic sludge from the pulp and paper mill treatment process in a pilot-scale digester (1 m 3 ) operated in dry, mesophilic conditions. The total weight ratio of dry straw to pig wastewater to sludge was 1 to1.25 to 0.5. The experiment was performed for a total of 153 days, however, the optimum period to balance the maximum energy output with the minimum retention time was determined to be 93 days. The addition of paper mill sludge accelerated VFA formation and gas production when compared to another pilot-scale digester operated under the same conditions without the sludge material. The straw in the pilot-scale digester with the sludge yielded 231 LCH 4 /kg VS within a 93-day digestion cycle compared to 189 days without the sludge. Daily leachate recirculation (0.2m 3 /m 3 straw-day), however, was not adequate for internal mixing and homogenization of the digester material. With adequate mixing, this co-digestion approach could enhance methane production and reduce the digestion time for untreated rice straw in a farm-scale digester.
