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
Hydrothermal pretreatment optimization for enhanced anaerobic digestion of willow sawdust
ALEXANDROPOULOU M., PAPADOPOULOU K., (Corresponding) ANTONOPOULOU G., LYBERATOS G.
Topic:
Solid waste management
Lignocellulosic biomass including agricultural and forestry residues such as willow sawdust could be used as feedstock for anaerobic digestion (AD). Hydrolysis has been shown to be the rate-limiting step in the case of AD of such substrates. Although being abundant, since the annual world...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
Removal of heavy metals from sewage sludge using combined hydrothermal pretreatment and chelate extraction
(Corresponding) Usťak S., Muňoz J.
Topic:
Wastewater treatment
The removal of heavy metals from sewage sludge using the combined influence of hydrothermal pretreatment and chelate extraction was tested. The classical method of batch extraction with chelates and the advanced hydrothermal pretreatment (HTP) extraction process with chelates were compared. Both...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

THE FATE OF MICROPLASTICS DURING THE ANAEROBIC DIGESTION OF THERMALLY PRETREATED SLUDGE
(Corresponding) Cesaro A., Pirozzi F., Zafirakou A., Alexandraki A.
Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
The presence of microplastics (MPs) in the water environment has raised as an issue of great concern, mainly due to their persistence and potential adverse effects on biota. Municipal wastewater treatment plants have been claimed among the most important point source of MPs. Nevertheless, they act...Read more
Pretreatment of Agro-Industrial Wastes with Basidial Fungi Strains for Effective Delignification of Lignocellulosic Wastes
(Corresponding) Kvesitadze G., Tsiklauri N., Kutateladze L., Urushadze ., Khokhashvili I., Sadunishvili T.
Topic:
Biowaste
Lignocellulosic biomass, including agro-industrial wastes, is an ideal cheap and abundant source of glucose for ethanol production. The complex structure of lignin makes it difficult to hydrolyze the biomass cellulose to sugars and other organic compounds. In recent years, it has become more and...Read more
