A comparative assessment of alkali-activated stabilisers including waste materials, for the treatment of swelling-shrinking soils

(Corresponding) Mavroulidou M., Gray C., Gunn M.

Topic:

Solid waste management

Swelling-shrinking soils (also known as expansive soils) experience very considerable volume changes upon changes in moisture content, thus causing major damages to lightweight structures, pavements, slopes and utilities. To counteract this problem chemical stabilisation of this type of soil with...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

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

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

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

Heavy metal assessment in vineyard sludge. Copper lixiviation and recovery studies.

(Corresponding) YOHAI L., GARRIDO MOLINA C., RESINA GALLEGO M., LÓPEZ MESAS M., VALIENTE M.

Topic:

Hazardous waste management

The use of copper-based compounds to prevent fungi diseases in vineyards have contributed to heavy metal accumulation in soil, vegetation and waste, causing a serious environmental and agro-industrial problem. One main issue is the waste generated both during and after wine production. This waste...Read more
