“…In addition to being useful as a straight fertiliser, it can be used to produce biogas for cooking, or-in briquette form-as fuel in ovens. Preliminary experiments indicate that Jatropha seedcake is a good feedstock for biogas production (Staubman, 1997;Karve, 2005;Visser and Adriaans, 2007). Moreover, the slurry that remains after digestion in the biogas plant can still be used as fertiliser, although it is debatable whether its quality is still the same as the raw seedcake.…”

“…This is probably due to the nutrients added during experiment and the difference in scale of experiment. Staubmann et al (1997) found that when using an anaerobic filter with Jatropha curcas seed cake as a substrate, 1 kg degraded COD yielded 248 l of CH 4 . Compared with the yield of 156 l/kg seed cake with batch mode in this study, CH 4 yield from banana stem waste (Kalia et al, 2000) and cotton oil cake (Isci and Demirer, 2007) were 196 l/kg and 78 l/kg of TS fed to the system, respectively.…”

“…Authors of these studies conclude that Jatropha curcas seed cake is a good source, due to the high conversion rates and efficiencies obtained. Staubmann et al (1997) studied the biogas production using a semicontinuous Upflow Anaerobic Sludge Blanket (UASB) reactor, a contact-process and an anaerobic filter. They found that the UASB reactor and the contact-process were not suitable for using this substrate but methane was produced well in the anaerobic filter.…”

Anaerobic conversion of Jatropha curcas seed cake was studied in a five-litre working volume batch reactor at 30°C. Over a 60-day operating period, a slurry of seed cake in water at a 1 : 20 seed cake-to-water ratio showed the highest methane yield of 296 litre methane/kg Chemical Oxygen Demand (COD) degraded (or 156 litre/kg of Jatropha curcas seed cake added) and achieved 52% COD removal. The results revealed that Jatropha curcas seed cake treated anaerobically can be a good source of methane, with optimal seed cake-to-water ratio in the range of 1 : 20 to 1 : 10.

Techno-Economic Models for Optimised Utilisation of Jatropha curcas Linnaeus under an Out-Grower Farming Scheme in Ghana

Abstract:Techno-economic models for optimised utilisation of jatropha oil under an out-grower farming scheme were developed based on different considerations for oil and by-product utilisation. Model 1: Out-grower scheme where oil is exported and press cake utilised for compost. Model 2: Out-grower scheme with six scenarios considered for the utilisation of oil and by-products. Linear programming models were developed based on outcomes of the models to optimise the use of the oil through profit maximisation. The findings revealed that Model 1 was financially viable from the processors' perspective but not for the farmer at seed price of $0.07/kg. All scenarios considered under Model 2 were financially viable from the processors perspective but not for the farmer at seed price of $0.07/kg; however, at seed price of $0.085/kg, financial viability was achieved for both parties. Optimising the utilisation of the oil resulted in an annual maximum profit of $123,300.
