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

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

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

EPS waste management from coastal cleaning actions: identification of contamination sources, collection, treatment, and re-use in cement-based materials

(Corresponding) Alexopoulos N., Filippidis A., Lekkas D., Metaxa Z., Prokopiou V.

Topic:

Recycling of materials to new products

Finding sustainable solutions to reduce plastic waste in response to today's global environmental challenges is a high priority for the scientific community. Collaboration among many scientists with diverse research interests is the key to success for integrated proposals for the collection,...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
