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

Seasonal fluctuations of PM2.5 concentrations at six Greek islands

(Corresponding) Fameli K., Kotrikla A., Polydoropoulou A., Mihalopoulos N., Grivas G., Stavroulas I.
Topic: 
Air pollution
PM2.5 concentrations in urban areas vary significantly spatially and seasonally. Measurements can be affected by multiply parameters such as anthropogenic activities, meteorological conditions as well as land use. In the present study one-year PM2.5 measurements from the network of low-cost sensors...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

Comparative evaluation between new construction and refurbishment of existing buildings with the exploitation of their Embodied Energy and Carbon Footprint

(Corresponding) KONDILI E., KALDELLIS I., ENTMONS A., PETROVITS N.
Topic: 
Circular economy and industrial symbiosis
On a global basis, buildings consume about 60% of raw materials per weight and almost 1/3 of the global energy consumption quantities. For many years the most important issue determining the sustainability of a building has been the energy consumed during its operation. However, recently a trend...Read more

Assessment of sustainability of extensive livestock farming in Central Greece (Evrytania prefecture) using S.W.O.T Analysis

(Corresponding) Bakogiorgos G., Lappa V., (Corresponding) Tasios A., Papadopoulos A., Pantera A.
Topic: 
Agroforestry, forest and agricultural sustainability
Animal husbandry, both in Greece and worldwide, is under constant threat, being at the center of multiple crises: wars, droughts, pandemics, successive economic crises. The increase in the prices of livestock inputs, especially after 2020, has tested and highlighted the strengths of the various...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

Time Evolution of Renewable Energy Applications Social Acceptability. The Wind Energy Case in Decarbonization Areas

Boulogiorgou D., (Corresponding) Kaldellis J.
Topic: 
Renewable energy sources
Energy transition policy towards zero carbon electricity generation by 2030/2050 in European as well in national level is based on increased exploitation of Renewable Energy Sources (RES) giving great importance to public opinion and public participation. Considering the above, it is important to...Read more

Lessons learned by modelling biogas production in an Italian state-of-the-art landfill active for 35 years

Folino A., Gentili E., Komilis D., (Corresponding) Calabrò P.
Topic: 
Solid waste management
"Fossetto" landfill is in operation in the municipality of Monsummano Terme (Tuscany, Italy) since 1988, at its origin, it was used as a controlled landfill where mixed municipal solid waste, without any separate collection, was disposed of. Since 2003, a biogas recovery system is active...Read more

Citizens Awareness Energy Park. The value of knowledge sharing and energy science in local communities.

Ktenidis P., Boulogiorgou D., Andrianopoulou A., Kavadias K., (Corresponding) Kaldellis J., Exarchakos G.
Topic: 
Participatory Science for Environmental Protection
Universities often act as a link between local communities and innovative research activities. In this context, this study explores the design of a Citizens Awareness Energy Park (CAEP) for demonstrating and disseminating knowledge to the local community. The CAEP aims in demonstrating applications...Read more

Fate Of Nitrofurans: Photochemistry, Transformation Products And Toxicity Evaluation In Surface Water Systems

Efthymiou C., Boti V., Konstantinou I., (Corresponding) Albanis T.
Topic: 
Emerging pollutants
Nitrofurans (NFs) consist a group of broad-spectrum antibiotic compounds provided as a basic dietary supplement in livestock husbandry as swine farms, beekeeping and aquaculture. Among nitrofurans furaltadone (FTD) is an antibiotic with a protective effect against bacterial and protozoan infections...Read more
