| Popis: | Turkey was the fourth and third largest producer of tomato and pepper fromgreenhouses, respectively, according to FAO in 2012. The huge amount of agricultural wastesgenerated from the production of tomato and green pepper are served as renewable sources forenergy production via anaerobic digestion (AD) For efficiently biogas production, it is essential todetermine the operation conditions of AD such as solid loading rate (SLR) for target wastes.The aim of this study is to optimize SLR for optimum biogas production from tomato and greenpepper wastes. For this purpose, biochemical methane potential tests were carried out at 37 °Cwith 7% and 15% of SLRs. For supplying the nutritional requirements of AD process, cow manurewas also added as a 10% of the selected SLR. As the biogas production from tomato wastes wasnearly 75% increased with the increase in SLR from 15% to 7%., the optimum SLR wasdetermined as 7% for anaerobic digestion of tomato wastes. On the other hand, decreasing SLR ofpepper waste from 15% to 7% is resulted with only 11% decrease in biogas production. When theenergy revenue between the 7% and 15% SLRs is compared with disposal cost of nearly two-foldpepper wastes, suitable SLR for pepper wastes can be suggested as 15%. Consequently, theoptimum SLR for anaerobic digestion of tomato and pepper was determined as 7% and 15%,respectively. |
