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
Challenges in biological treatment plants: the approach of zero sludge waste
THEOFANIDIS S., Samiotis G., Bellos D., Pekridis G., Tsioptsias C., (Corresponding) Amanatidou E.
Topic:
Wastewater treatment
The current trend in operation of biological Wastewater Treatment Plants (WWTPs) is the minimization of sludge wastage due to its labor and cost intensive management process. Minimization of sludge can be achieved by increasing the solids retention time (SRT) in a WWTP, up to an almost complete...Read more
Extraction of Oil from Spent Grounds Coffee using Ultrasound as Pre-Extraction Method
(Corresponding) Cubas A., Hermmann K., Bianchet R., Moecke E.
Topic:
Food waste
The treatment and processing of coffee annually produces a large volume of biological waste, which contributes to environmental pollution, it is estimated that coffee production generates approx. 6 million tonnes of spent coffee grounds per year in the world (GETACHEW and CHUN, 2017). Thus, the...Read more

Aerobic degradation of tetramethyl ammonium hydroxide (TMAH) from effluents of semiconductor industries: kinetic studies of laboratory and pilot experiments
(Corresponding) Innocenzi V., De Michelis I., Ippolito N., Mazziotti Di Celso G., Prisciandaro M., Vegliò F.
Topic:
Wastewater treatment
Aerobic degradation of effluents contains tetramethylammonium hydroxide molecules (TMAH), coming from an electronic industry, were studied at laboratory and pilot scale. At the first, the preliminary experiments were conducted using a lab scale reactor inoculated with activated sludge coming from...Read more

Elimination of relevant pharmaceuticals in hospital wastewater from Colombia by combination of a biological system with a sonochemical process
(Corresponding) TORRES PALMA R., Serna-Galvis E., Silva-Agredo J.
Topic:
Advanced oxidation processes
This work presents the treatment of selected emerging concern pharmaceuticals in real hospital wastewater (HWW) from Tumaco-Colombia by combination of a biological system with a sonochemical process. Fifteen compounds, commonly present in HWW, were considered: acetaminophen, diclofenac,...Read more
Use of a two-stage MBBR system for medium-strength dairy wastewater treatment
Katsara A., Iliopoulou A., Zkeri E., Aloupi M., Fountoulakis M., (Corresponding) Stasinakis A.
Topic:
Wastewater treatment
A two-stage Moving Bed Biofilm Reactor (MBBR) system consisting of a methanogenic and an aerobic reactor in series was used for medium strength dairy wastewater treatment. An energy analysis was conducted for the methanogenic MBBR to investigate its autonomy and its potential to act as a...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
Upgrading from biogas to biomethane is currently growing in Europe for economical and sustainable aspects. To date different treatments are proposed to upgrade biogas to a higher fuel standard. Among these, physico-chemical treatments are spreading widely in the biogas technology market...Read more

Topic:
New solutions for a better and sustainable agriculture
Due to the rapid growth of global populations, ensuring sufficient agricultural inputs with has become a new challenge for the scientific community. Moulds contamination of grains represents a major cause of food spoilage, according to statistics over 20% of global cereals production being...Read more
Mapping of available biological feedstock streams: The case of agro-industrial waste and by-products in the Region of Central Macedonia - Greece
(Corresponding) Patsios S., Batsioula M., Skoutida S., Geroliolios D., Melas L., Karkanias C., Karanasiou A., Saliakellis P., Malamakis A., Banias G.
Topic:
Sustainable production and management of biomass
The European Union’s Bioeconomy Strategy aims to the transition to a circular, sustainable bio-based economy. It should be highlighted that bio-based production systems face significant challenges concerning the sustainable availability of the biological materials that are used as feedstocks for...Read more
