High Solid Anaerobic Co-Digestion of Household Organic Waste with Cow Manure for Mass and Energy Recovery

This article intends to promote the usage of potato peels as efficient substrate for the anaerobic digestion process for energy recovery and waste abatement. This study examined the performance of anaerobic digestion of potato peels in different inoculum-to-substrate ratios. In addition, the impact of combined treatment with cow manure and pretreatment of potato peels was examined. It was found that co-digestion of potato peel waste and cow manure yielded up to 237.4 mL CH4/g VSadded, whereas the maximum methane yield from the mono-digestion of potato peels was 217.8 mL CH4/g VSadded. Comparing the co-digestion to mono-digestion of potato peels, co-digestion in PPW/CM ratio of 60:40 increased the methane yield by 10%. In addition, grinding and acid hydrolysis applied to potato peels were positively effective in increasing the methane amount reaching 260.3 and 283.4 mL CH4/g VSadded respectively. Likewise, compared to untreated potato peels, pretreatment led to an elevation of the methane amount by 9% and 17% respectively and alleviated the kinetics of biogas production.

Demonstration Plant

Recycling of Municipal Solid Waste is vigorously promoted in Japan and the necessity of energy recovery from organic waste is increasing. An anaerobic digestion demonstration plant for organic waste in Kyoto City, Japan has been operated for about two years. Three kinds of wastes (garbage and leftovers from hotels, yard waste and used paper) mixed at various ratios are used. The plant has maintained stable operations with each mixture, generating biogas by the decomposition of VS at the rate of about 820 m3N/ton-VS.

Degradation Reactions

Although anaerobic degradation reactions of organic waste are feasible, and have been studied since 1990. However, until now, optimizing the reaction rate to get the highest methane yield is still needed. Therefore, it is necessary to optimize the operational parameters. The goal of this study is to investigate the impacts of temperature, ratio of solid waste and innoculum, and total solid percentage to the anaerobic degradation reactions. Solid waste was the mixture of water hyacinth (representative of plant components in the organic waste stream) and cow manure (ratio of water hyacinth: cow manure = 2:1). The mixture was composted until getting a homogenous texture in order to facilitate for the anaerobic digestion process. Two temperature conditions (55 oC and 37 oC), three solid wasteinoculum (S:I) ratios (1:2, 2:1, 1:1) and five percentages of total solid (30 %, 24 %, 18 %, 14 %, 10 %) were investigated. The result indicated that in the thermophilic condition (55 oC), 24 % TS, and S:I ratio of 1:2, the reactor generated the highest methane yield after 30 days.

Inadequate management of solid organic waste can lead to the spread of diseases and negatively affects the environment. Fermentation and vermicomposting of organic waste could have dual benefits by generating earthworm biomass for a source of animal feed protein, and, at the same time, turning the organic waste into readily used compost. This study investigated the effect of an organic waste source (as a sole source or blended with others) totaling 24 media for the cultivation of the earthworm Eisenia foetida. Eight media sources were applied, namely cow manure, horse manure, goat manure, broiler chicken manure, market organic waste, household organic waste, rice straw, and beef rumen content. E. foetida was cultivated for 40 days, then the number of cocoons, earthworms, and the total biomass weight were measured at the end of the cultivation. Results demonstrated that the media source affected E. foetida earthworm cultivation. The most effective media were those containing horse manure that led to the production of the highest earthworms and the highest biomass. The produced cocoons and earthworms were poorly correlated with an r-value of 0.26 and p-value of 0.21. Meanwhile, the number and weight of the earthworms correlated well with an r-value of 0.784 and p-value of <0.01. However, the average numbers and weights of the produced earthworms in the media containing horse manure, cow manure, goat manure, and non-blended organic waste were insignificant. Overall results suggest that blended organic wastes can undergo composting to produce nutrient-rich earthworm biomass while turning the solid organic waste into readily used compost.

Main Material

Magetan society rarely take advantage of the organic waste. So it is necessary to do research on composting. This study aims to determine the effectiveness of sewage treatmentusing cabbage and mango leaves as main material and activator used were cow dung, goatdung and EM4. This is a pre-experimental research. Data collected by the experiment, measured andobserved. 27 samples of 3 diferent-processes were 9 sample using cow manure activators, 9second sample using goat droppings activator and 9 third sample using activator EM4. Thedata were then analyzed by calculating the average weight reduction of waste.Analyses usingANOVA test. Based on the result of statistical test, it is known ρ sign 0,000 < α (0,01) so that Hisaccepted or no difference to the effectiveness on variation activator mixture of cabbage andmango leaves as compost. The results showed that the use of cow dung activators weightdecreased 28.20%, temperature (27-37) ° C, pH (6.6 to 7), humidity (55-70)%. The use ofgoat dung activators weight down 40.90%, temperature (28-39) ° C, pH (6.7 to 7), humidity(65-75)%. The use of EM4 weight decreased 61%, temperature (27-40) ° C, pH (6.6 to 7),humidity (55-75)%. We recommend using EM4 activatorbecause the result is the best. Keep thetemperature and humidity so that the composting process is going well.
