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

Evaluation of Pressure-Driven Membrane Processes for Nutrients Recovery from Dilute Effluents
Tsaridou C., Karanasiou A., (Corresponding) Plakas K., Karabelas A.
Topic:
Circular economy and industrial symbiosis
Results are presented from an ongoing R&D project, aiming at full utilization of dairy-industry effluents. Development of a membrane-based method is pursued, for treatment of digestate (after fermentation yielding bio-gas) to recover nutrients (N-NH4, P-PO4) and water for reuse/recycling or...Read more
