IMPROVING INNOVATION CAPACITIES OF PRIVATE AND PUBLIC ACTORS FOR SUSTAINABLE AND PROFITABLE RECYCLING OF LIVESTOCK WASTE
(Corresponding) Antoniou M., Kallikazarou N., Koutsokeras L., Constantinides G., Constantinide E.
Topic:
Water and wastewater reuse
The Mediterranean region is known for its intensive livestock farming, especially for the breeding of pigs and cattle. These activities result in vast amounts of waste that necessitate proper treatment. Inadequate manure treatment can cause eutrophication of surface waters, enrichment of nitrates...Read more
A detailed characterisation of household food waste and the implications of sorting behaviour on potentials for anaerobic digestion and nutrient recovery
(Corresponding) Walk S., Hausbeck G., Körner I.
Topic:
Food waste
This study investigates household food waste (HH FW) generation in two socio-economically different areas in Lübeck, Germany. The applied waste characterisation protocol provided a detailed insight into the generation and separation behavior of FW collected in the municipal collection system. In...Read more
How does presence of microplastics impact biogas production?
Resnik N., (Corresponding) Žgajnar Gotvajn A., Griessler Bulc T.
Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
The aim of this study was to evaluate the inhibition on the biogas production caused by microplastics (MPs). Wastewater treatment plants (WWTPs) are receptors of MP. After wastewater treating, more than 90% of MP could be retained in the sludge. Anaerobic digestion of the excess sludge can help...Read more
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
Quantification of feedstocks and outputs for a regional Bioeconomy using the AD Biorefinery concept.
(Corresponding) Curry R., Blaine L.
Topic:
Circular economy and industrial symbiosis
Greenhouse gas emissions (GHG’s) from agriculture in Northern Ireland account for over 27% of regional emissions, as opposed to 7% for the UK overall, leaving the region with challenges in meeting climate abatement targets. The development of a sustainable regional Bioeconomy has been identified as...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

In-situ bioremediation of groundwater polluted with Cr(VI) under anaerobic conditions
Galani A., Anastopoulou P., Noutsopoulos C., (Corresponding) Mamais D.
Topic:
Soil and groundwater contamination and remediation
The natural capacity of several microbes to reduce Cr(VI) to Cr(III) has been considered of much interest in order to remediate soil and groundwater polluted with Cr(VI). The objective of this work is to evaluate the enhancement of the activity of indigenous Cr(VI) reducing bacteria by the addition...Read more
Anaerobic Digestion of Municipal Wastewater (MWW) in a Periodic Anaerobic Baffled Reactor (PABR)
Zarkaliou A., Kougias C., (Corresponding) Papadopoulou K., Lyberatos G.
Topic:
Wastewater treatment
The scope of this work is to study the treatment of municipal wastewater in a Periodic Anaerobic Baffled Reactor (PABR). PABR is an innovative, high-rate bioreactor, designed to operate under high organic loadings. Apart from the Hydraulic Retention Time (HRT) an important operational parameter is...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
