Comparative analysis of WtE technologies based on multiple criteria analysis and life cycle considerations
Mertzanakis C., (Corresponding) VLACHOKOSTAS C.
Topic:
Waste strategies development
Nowadays, a range of alternative options and technologies for Waste to Energy are currently available and analytically discussed in the effort to promote energy production and rational waste management. In this paper, a generic methodological scheme is proposed for the comparative analysis of WtE (...Read more
Removal Of Ciprofloxacin From Waste Water By Photocatalytic Method With Waste Polystyrene And Tio2 Composites
(Corresponding) Hayri-Senel T., Kahraman E., Sezer S., Erdol-Aydin N., Nasun-Saygili G.
Topic:
Wastewater treatment
Ciprofloxacin (CIP) is one of the widely used antibiotics. Since ciprofloxacin in the aquatic ecosystem adversely affects human health as well as other organisms, it must be removed from wastewater.
The aim of this study was to develop polystyrene (PS) and TiO2 composites that can be used as...Read more
Development of Scenario-based Decision-Making Framework for Marine Oil Spill Waste Management
Hosseinipooya A., (Corresponding) Li J.
Topic:
Waste management
This study developed a scenario-based decision-making framework to help select the appropriate strategy to deal with marine oil spill response waste by considering different impact factors, including the type of spilled oil, the quantity and quality of waste, the capacity of transportation, the...Read more
Investigating the Performance of Anaerobic Co-Digestion of Primary Sludge and Acid Whey Using a Twin Pilot Scale System
(Corresponding) Gkoumas F., Tzivelou E., Gravanis Z., Mamais D., Malamis S., Noutsopoulos C.
Topic:
Waste-to-energy
Anaerobic Digestion (AD) has proven to be an effective method for transforming organic waste into biogas, a renewable energy source that can play a crucial role in reducing our dependence on finite fossil fuels. Despite its widespread use, mono-digestion, where a single substrate is utilized, is...Read more
Circular bioeconomy in the sustainable biotransformation of agri-food residues and waste
BUTU M., (Corresponding) RODINO S., (Corresponding) BUTU A.
Topic:
Waste strategies development
This paper explores the potential of sustainable biotransformation of agri-food residues and waste into a spectrum of marketable ingredients for food and feed and other bio-based products (biochemicals, biomaterials) which is at the heart of the bioeconomy. With over 80% of land covered by farms or...Read more

Improved storage and handling of fine recycled concrete aggregates by accelerated carbonation: towards a quantification method
Vogt S., Koeniger L., Brück F., (Corresponding) Weigand H.
Topic:
Construction and demolition waste
The fines fraction generated by crushing of concrete waste for production of recycled concrete aggregates amounts to 40 - 60 mass-%. Technically, fine recycled concrete aggregates (0 - 2 mm, fRCA) may be employed as a sand substitute in new concrete products. This is, however, hampered by the...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

Polyhydroxyalkanoates (PHAs) Production from the Liquid Fraction of dried/shredded Food Waste
Filippou K., Bouzani E., Kora E., Ntaikou I., (Corresponding) Papadopoulou K., Lyberatos G.
Topic:
Bioplastics
An enriched culture of Polyhydroxyalkanoates (PHAs)-forming bacteria was developed using the liquid fraction (condensate) which is generated during drying and shredding of food waste. A mixed enriched culture was used for the production of PHAs, in two Draw-Fill Reactors (DFRs). The culture was...Read more
Chemical properties of plant-based biochar to be used as soil fertiliser in Galicia (NW Spain)
Ferreiro-Domínguez N., Salman S., (Corresponding) Mosquera-Losada M.
Topic:
Recycling of materials to new products
The excessive use of chemical fertilisers can cause soil acidification, depletion of soil quality, and biodiversity loss. Alternatively, biochar can improve crop productivity due to its ability to bind macronutrients and micronutrients and also adsorb various contaminants. However, the properties...Read more

A study of the properties of alkali activated cement concrete with potassium carbonate activator.
(Corresponding) Mavroulidou M.
Topic:
Net Zero emission transition
Alkali-activated cements (AAC) have recently attracted the vivid interest of the civil engineering industry as promising innovative alternatives to Portland Cement (PC) which is responsible for 8% of anthropogenic CO2 emissions. In this context, this paper studies concrete produced using potassium...Read more
