Development and promotion of the WEEE prevention culture in Greece
(Corresponding) Charitopoulou T., Vogiatzidaki E., Gkitzeni I., Malliaris M.
Topic:
Electric and electronic waste
WEEE streams challenge the goals towards a circular economy, since WEEE contain valuable and scarce resources that could be prepared for a second life or recovered. In the framework of the project LIFE REWEEE (LIFE14 ENV/GR/000858), Hellenic Recycling Agency (HRA) aims to raise awareness among...Read more

Transferring the Carbonation of Biomass Bottom Ash from Batch to Continuous Operation
(Corresponding) Schnabel K., Brück F., Pohl S., Weigand H.
Topic:
Mineral carbonation of alkaline waste materials
Biomass incineration residues may be used for CO2 capture and storage by carbonation of waste-borne metal hydroxides. Moist carbonation of these ashes can be performed under mild conditions (ambient pressure and temperature) and accelerated by using a CO2-rich gas. The process requires the wetting...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

Use of food waste as culture media in biocementation for ground improvement applications
Mwandira W., (Corresponding) Mavroulidou M., Gunn M., Gray C.
Topic:
CIRCULAR ECONOMY AND BIOECONOMY
The paper investigates the use of mixed fruit and vegetable (FV) waste to extract liquid to grow bacteria. The bacteria will be used to induce biocementation of soils and two metabolic pathways are examined. These are the ureolytic pathway and the carbonic anhydrase pathway (which absorbs CO2)...Read more
