An overview of pressure-driven membrane technologies for a sustainable recovery of volatile fatty acids (VFAs)
Pervez M., Mahboubi A., Hasan S., Cai Y., Zarra T., Belgiorno V., Taherzadeh M., (Corresponding) Naddeo V.
Topic:
Food waste
Currently, petroleum-based volatile fatty acids (VFAs) sources are not acceptable towards sustainable development goals (SDG); therefore, biobased-derived VFAs are of interest. Anaerobic digestion has been identified as a useful technology for the production of biobased VFAs from organic waste...Read more
Can the seasonal variability affect the BMP of fruit and vegetable waste?
(Corresponding) Scotto di Perta E., Lamboglia R., Cesaro A., Frunzo L., Esposito G., Papirio S.
Topic:
Food waste
Fruit and vegetable waste (FVW), largely produced in open markets, is characterized by highly putrescible materials, thus being a proper substrate for anaerobic digestion. This study investigated the effect of the seasonal variation of FVW, on the biochemical methane potential (BMP). To this end,...Read more

Nutrients recovery from anaerobic digestion effluent for the production of microalgae biomass
(Corresponding) Psachoulia P., Schortsianiti S., Dergiade I., Chatzidoukas C., Samaras P.
Topic:
Wastewater treatment
The efficient management of anaerobic digestion effluents (ADEs) from biogas plants has raised increasing environmental concerns, as a result of their high content in nutrients, mostly in the form of NH4- and PO4-. Their discharge to farmlands is restricted due to irrigation guidelines, while...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

Exploring the effects of static magnetic fields for the enhanced valorization of sewage sludge by anaerobic digestion
(Corresponding) Di Costanzo N., Cesaro A., Di Capua F., Mascolo M., Esposito G.
Topic:
Waste management
Anaerobic digestion (AD) is an interesting and sustainable option to handle sewage sludge (SS), as it generates a methane-rich biogas and a digestate with potential fertilizing properties. Several strategies have been proposed to enhance AD performances and the valorization of SS. Among these, the...Read more

Nutrients recovery from liquid anaerobic digestate by combining nanofiltration and struvite precipitation - The case of dairy effluents valorization
Tsaridou C., (Corresponding) Karanasiou A., Sioutopoulos D., Plakas K., Tzioumaklis C., Patsikas N., Gliaos P., Karabelas A.
Topic:
Sustainable supply of raw materials
Results are reported herein of a study aiming to develop an integrated process for valorizing liquid digestate (LD) from an industrial anaerobic digestion (AD) plant treating dairy-processing effluents. The investigated approach involves LD treatment by nanofiltration (NF) membranes, at pilot-scale...Read more
