Abstract
India is one of the largest cultivators of banana and cauliflower crops in the world. However, these crops generate huge amounts of wastes whose disposal in an eco-benign way has become a challenging issue. Banana peduncle and cauliflower wastes are promising substrates for bioenergy production through anaerobic digestion (AD). In this present study, shredding and extrusion pretreatment were applied to increase biogas production from banana and cauliflower wastes and the results were compared. Batch anaerobic digestion tests were carried out in 1-L batch AD reactors at a temperature of 37 °C with a substrate to inoculum ratio of 0.5, by following VDI 4630 standards. AD of the extruded cauliflower waste showed a maximum specific biogas yield (SBY) of 587.4 mL/g volatile solids (VS) added, which is 9.8% higher than shredded cauliflower waste (with SBY of 534.7 mL/g VS added). Similarly, AD of the extruded banana peduncle revealed a maximum SBY of 399.2 mL/g VS added, which is 16.5% higher than shredded banana peduncle (with SBY of 342.5 mL/g VS added). The modified Gompertz and logistic kinetic models showed the best fit for biogas production. Thus, it is concluded that the anaerobic digestion of wastes with extrusion as pretreatment could improve biogas production and solid waste management effectively and reduce the waste disposed into dumpsites/landfills.
