SusNisia: Circular economy for biogenic residues for the North Aegean – case studies for Islands of Chios and Lesvos

Baur F., Porzig M., Lekkas D.
Topic: 
Biowaste
The North Aegean Islands of Chios and Lesvos set recycling goals for organic residues from MSW. Both islands, in line with the National and the Regional Plans for Municipal Waste Management, have selected the approach of mechanical-biological stabilization of MSW in combination with separated...Read more

Biogas production from sunflower residues: effect of pretreatment

(Corresponding) Stamatelatou K., Spyridonidis A., Zhurka M., Vasiliadou I., Lytra V.
Topic: 
Biowaste
Sunflower residues are a prominent substrate of renewable source for biogas production during anaerobic digestion (AD). However, due to its recalcitrant structure, pretreatment is necessary to increase its biodegradability. The objective of the present work was to evaluate the effect of the NaOH...Read more

Bioaugmentation process for PAHs contaminated soil remediation through microbial inocula from anaerobic treatment of lignocellulosic substrate

(Corresponding) Ferraro A., Massini G., Mazzurco Miritana V., Panico A., Pontoni L., Race M., Rosa S., Signorini A., Fabbricino M., Pirozzi F.
Topic: 
Soil and groundwater contamination and remediation
In the present work, an anaerobic bioremediation treatment was investigated for reclamation of polycyclic aromatic hydrocarbons (PAHs) contaminated soil. The PAHs contaminated soil was artificially prepared and seven different contamination conditions were tested. In particular, four soils were...Read more

Optimization of decentralized treatment and sanitation of domestic wastewaters via constructed wetlands: The DOMUS_CW project

(Corresponding) Ntaikou I., Antonopoulou G., Vyrides I., Drakopoulos V., Dailianis S., Lyberatos G.
Topic: 
Wastewater treatment
The DOMUS_CW project proposes the adoption of a simple, cost efficient and highly effective practice for the treatment of domestic/household wastewaters in rural areas of Balkan and Mediterranean (BalkanMed) countries, i.e. treatment via constructed wetlands (CWs). Two free surface flow CWs...Read more

Biosolids as soil-amendment: evaluation of nutrient leaching in loamy-silty soil

(Corresponding) Venegas M., Fernandez G., Vidal G.
Topic: 
Biowaste
Municipal sewage sludge is a by-product of wastewater treatment. The amount of sewage sludge has increased with the construction and expansion of wastewater treatment plants, while stricter policies have limited its disposal. Anaerobic digestion is a worldwide technology used in sewage sludge...Read more

Start-up of the nitrogen removal process in an anaerobic up-flow reactor inoculated with aeration tank sludge

Wijaya I., (Corresponding) Ribeiro H., Soedjono E., Slamet ., Teixeira C., Bordalo A.
Topic: 
Wastewater treatment
Anaerobic ammonium oxidation (anammox) has been considered a promisingly alternative to traditional nitrification/denitrification to remove nitrogen in an autotrophic process, without using an external carbon source, requiring low energy consumption and sludge production. The start-up of the...Read more

Anaerobic digestion of long-chain fatty acids (oleic, palmitic, stearic) with whey protein as the emulsifier

(Corresponding) Eftaxias A., Michailidis C., Diamantis V., Aivasidis A.
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

High-rate anaerobic co-digestion of agro-industrial wastes combined with ammonia recovery and biogas purification

Eftaxias A., Georgiou D., (Corresponding) Diamantis V., Koumara A., Koskinari M., Aivasidis A.
Topic: 
Environmental biotechnology and bioenergy
Screened dairy manure, pressure-sterilized animal by-products, and cheese whey were co-digested in a Plug Flow Reactor (PFR) over a period of 150 days. The mixture was characterized by TCOD = 70±8 g/L, SCOD = 26±6 g/L, NH4-N = 1.5±0.3 g/L, TSS = 20±5 g/L, VSS = 18±6 g/L, TS = 33±5 g/L, VS = 26±2 g/...Read more

Anaerobic MBR technology for treating municipal wastewater at ambient temperatures

(Corresponding) Plevri A., Mamais D., Noutsopoulos C.
Topic: 
Wastewater treatment
An innovative way to treat municipal wastewater and produce energy at the same time is anaerobic treatment. Anaerobic processes are traditionally used for high-strength wastewater or municipal sludge treatment and only recently have been applied for the treatment of low strength municipal...Read more

Anaerobic co-digestion of poultry manure and used cooking oil for enhanced biogas production

(Corresponding) Eftaxias A., Gkalimanis P., Koskinari M., Koumara A., Diamantis V., (Corresponding) Aivasidis A.
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
