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
ORGANIC SOLID WASTE MECHANICAL PRETREATMENT FOR THE OPTIMIZATION OF ANAEROBIC DIGESTION PROCESSES
(Corresponding) Cesaro A., Cieri V., Belgiorno V.
Topic:
Biowaste
Anaerobic digestion has been recognized as the most demanding process for the valorization of organic solid waste towards the production of several, valuable intermediates (Dahiya et al., 2018), which can be further converted to a methane rich-gas to meet the current needs for renewable energy...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

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
Valorisation of ovine cheese whey through PHA production
(Corresponding) Asunis F., Brundu A., Carucci A., Cocco F., De Gioannis G., Isipato M., Muntoni A., Spiga D.
Topic:
Biowaste
The ovine dairy supply chain plays an important role in Mediterranean economic systems and is experiencing a much needed phase of development and innovation looking beyond traditional dairy products. The same attention to innovation has not yet been applied to the management of the effluents...Read more
The cultivation of Penicillium strain, isolated from rotten vegetables, on potatoe dextrose broth (PDB) medium enriched in arginine and mineral elements, allowed to obtain a yield of 31.7 mg/g of dry biomass and 9 mg/g of dry biomass into chitin and natural chitosan, respectively. The infrared...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

Optimum technical operating conditions and treatments for the production of high-purity struvite fertilizer from livestock wastewater.
Kallikazarou N., Koutsokeras L., Constantinide E., Constantinides G., (Corresponding) Antoniou M.
Topic:
Biowaste
Inadequate treatment of nutrient-rich waste streams originating from human activities such as agriculture, animal breeding, urbanization, and industrialization causes an array of environmental problems. Among them are eutrophication of surface water, nutrients and pathogens leaching into...Read more
Modelling the hydrothermal carbonization of cheese whey wastewater in Lesvos island: an application of the 3-step evolution model
Chatzimaliakas P., (Corresponding) Vakalis S.
Topic:
Biowaste
Lesvos island has an extensive dairy production sector, and -at present- eighteen dairy processing facilities are operating. Efficient management of the liquid biowaste effluents has been an issue of interest since the scope is the minimization of the environmental impact. The operating dairy...Read more
