Optimum Solid Loading Rate for Biogas Production from Agricultural Wastes
Öz
Turkey was the fourth and third largest producer of tomato and pepper from
greenhouses, respectively, according to FAO in 2012. The huge amount of agricultural wastes
generated from the production of tomato and green pepper are served as renewable sources for
energy production via anaerobic digestion (AD) For efficiently biogas production, it is essential to
determine 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 green
pepper wastes. For this purpose, biochemical methane potential tests were carried out at 37 °C
with 7% and 15% of SLRs. For supplying the nutritional requirements of AD process, cow manure
was also added as a 10% of the selected SLR. As the biogas production from tomato wastes was
nearly 75% increased with the increase in SLR from 15% to 7%., the optimum SLR was
determined as 7% for anaerobic digestion of tomato wastes. On the other hand, decreasing SLR of
pepper waste from 15% to 7% is resulted with only 11% decrease in biogas production. When the
energy revenue between the 7% and 15% SLRs is compared with disposal cost of nearly two-fold
pepper wastes, suitable SLR for pepper wastes can be suggested as 15%. Consequently, the
optimum SLR for anaerobic digestion of tomato and pepper was determined as 7% and 15%,
respectively.
