Topic:
Environmental biotechnology and bioenergy
Long chain fatty acids are suitable for biogas production, however, they are often responsible for process inhibition, due to their high toxicity even at low concentrations. In this study, anaerobic co-digestion of whey protein emulsified with oleic, palmitic or stearic acid were examined in...Read more

Topic:
Biowaste
Aim of this study was to evaluate the anaerobic co-digestion of diluted poultry manure (DPM) and used cooking oil (UCO). Mixtures of DPM with different UCO dosages (1 to 6% v/v) were prepared using a high-shear emulsifier and digested in batch anaerobic reactors. Increasing the UCO dosage resulted...Read more

Seasonal variation of the biochemical methane potential of fruit and vegetable wastes produced in the Mediterranean area
Kalogiannis A., Vasiliadou I., (Corresponding) Stamatelatou K.
Topic:
Food waste
Fruit and vegetable wastes produced massively in open markets are a suitable feedstock for biogas production and digestate of high fertilizing value. A first step of designing anaerobic digestion systems for treating these wastes efficiently is to study the impact of the seasonal variation on the...Read more
