Development of Advanced Electrokinetic Separation for Sulfur-Containing Hot Spring Discharge with High Acidity

Lin Y., Tseng P., Fan C., (Corresponding) Pan S.

Topic:

Water and wastewater reuse

Hot springs at the Beituo district, Taiwan are well-known for containing a significant amount of white or blue sulphur. With strong acidity and high conductivity, the used hot springs water did not meet the effluent water quality standards of the sewerage system. Discharging without appropriate...Read more

CIRC4FooD: An urban food production system inspired by the circular economy

(Corresponding) Tsatsou A., Ioannides C., Noutsopoulos C., Tsimiklis G., Chrisomallos G., Tsiropoulos Z., Mamais D., Malamis S.

Topic:

Spatial environmental planning

The environmental footprint of the current, linear food system is a key challenge that must be faced for a global transition to sustainability. Agricultural practices are drivers of polluting food production, while cities form critical hubs of wasteful food consumption. In this context, urban...Read more

The environmental benefits of small-scale timber frame dwellings for utilization of forested and rural remote areas in Greece

(Corresponding) Psilovikos T., (Corresponding) Stergiadou A., Moutsopoulos D.

Topic:

Spatial environmental planning

Wood is the only renewable material produced by photosynthesis. Wood has the ability to preserve the stored carbon in its molecular structure as long as remain within a structure. Small-scalelightweight timber dwellings are gaining recognition in Europe after the dominance of concrete and steel...Read more

Implementing Circular Economy in Wineries: The Case of Greece

(Corresponding) Kounani A., Sotiropoulou E., Seleventi M.

Topic:

Circular economy and industrial symbiosis

Grape is considered one of the largest fruit crops in the world, since its 2017 production, the vast majority of which was used in winemaking, reached 74 MT globally and 24 MT in the EU. The main target of this paper is to highlight the urgent need for transforming the linear model into a circular...Read more

Nothing to Waste: A Green Venture Business Model supporting local communities to Circular Economy pathways

(Corresponding) TRITOPOULOU E., Malliaris M., Cretsi Bacolas N.

Topic:

Circular economy and industrial symbiosis

Nothing-to-Waste is a green venture about the promotion and implementation of circular economy in the area of Western Thessaloniki, Greece, where 24 businesses are attempting to self-manage their waste in sustainable way. The project is being planned, implemented, coordinated and monitored by...Read more

Dredged sediments as a natural resource

(Corresponding) ANAGNOSTOPOULOU K., CAVOURA O., SOUMPASAKOU G., DAMIKOUKA I.

Topic:

Circular economy and industrial symbiosis

The periodic removal of sediments is necessary to ensure the functionality of ports, to facilitate navigation, for construction, expansion and environmental cleanup processes. The management and fate of the resultant tons of dredged material is a costly issue that must be addressed. Many...Read more

Symbiotic actions for CO2 capture and utilization in Cyprus

DIMA C., ANGELIS-DIMAKIS A., (Corresponding) ARAMPATZIS G.

Topic:

Circular economy and industrial symbiosis

CO2 capture and utilisation (CCU) is one of the main pillars of EU strategy towards the reduction of the greenhouse gases. The development of symbiotic actions between CO2-emitting industries and potential receivers not only contributes to the above advantages but also has the possibility of...Read more

Energy recovery from urea in decentralised wastewater streams

Asiain-Mira R., Zamora P., Rogalla F., Monsalvo V., (Corresponding) Torrente-Murciano L.

Topic:

Water, energy and/or food nexus

This work presents the design of a new process that enables energy recovery from wastewater, based on the selective adsorption of urea from urine and its subsequent decomposition into hydrogen. Removal of nitrogen compounds is at the core of wastewater treatment, as their uncontrolled discharge...Read more

Rodríguez-Rigueiro F., Santiago-Freijanes J., Ferreiro-Domínguez N., (Corresponding) Mosquera-Losada M.

Topic:

Agroforestry, forest and agricultural sustainability

Agroforestry is recognised as climate-smart agriculture, being a powerful tool for climate change mitigation and adaptation. Considering knowledge transfer a capital challenge to overcome the needed transition towards this for the European Commission, the AFINET (AgroForestry Innovation NETworks)...Read more
