Abstract : Harvested pistachio nuts are covered with organic hull which is removed by de-hulling process. Most of the
pistachio by-products which are produced during de-hulling process are considered as agricultural waste and often mixed
with soil, to a lesser extent are used as feedstuff by local livestock farmers and a small portion is used as herbal medicine.
This study investigated the anaerobic treatability and biogas generation potential of pistachio hull waste. The effect of pretreatment
on biogas generation potential was investigated. For this purpose, Biochemical Methane Potential (BMP) Assays
were conducted for two Chemical Oxygen Demand (COD) concentrations of 22 and 33 g tCOD l-1 at the absence and
presence of chemical and thermal pre-treatment methods. The results revealed anaerobic digestion of the pistachio de-hulling
wastes and subsequent biogas production as a renewable energy source are possible. The observed percent COD removal and
methane yield values of the pre-treated pistachio de-hulling waste samples were significantly higher than the raw pistachio
de-hulling waste. The highest methane yield was observed as 213.4 ml CH4/g COD.
Key words- Pistachio de-hulling waste, biogas, renewable energy, pre-treatment.
