Comparative studies of the equilibrium adsorption of CO2 onto coal ash zeolites Na-X and Na-Ca-X
(Corresponding) Boycheva S., Marinov I., Miteva S., Zgureva D.
Topic:
Climate change mitigation and adaptation
Coal-fired Thermal Power Plants (TPPs) are the main source of greenhouse gas emissions in the atmosphere, but they also generate huge amounts of solid by-products, including fly ash (FA). A modern strategy for sustainable energy production is to improve the ecology of the TPPs by developing...Read more

LED light tailoring in a planar photobioreactor for optimization of microalgae growth.
(Corresponding) Riggio V., Occhipinti A., Grinic D., Zanetti M.
Topic:
Environmental biotechnology and bioenergy
Microalgae are well known for their potential in producing valuable substances for nutraceutical and pharmaceutical industries, as well as a source of biofuel. Currently, the use of the photosynthetic capacity of microalgae is a new alternative for carbon dioxide bio-fixation. Therefore, the...Read more

Coal ash zeolite as a self-catalytic-chemisorption system for conversion of carbon dioxide to hydrocarbons
(Corresponding) Boycheva S., Zgureva D.
Topic:
Climate change mitigation and adaptation
At present, the developments of sustainable carbon capture technologies are of the main scientific and technological priority required to mitigate the over generation of greenhouse gases. Three CO2 clean energy production approaches have been outlined: pre-combustion capture, oxy-fuel combustion...Read more

Numerical simulation of CO2-brine-rock interactions on CO2 sequestration in Shihezi Formation of Ordos Basin in China
(Corresponding) Liu B., Li Z., Fu X.
Topic:
Energy technologies and sustainability
Carbon Capture and Storage (CCS), as the best way of reducing carbon emissions under existing technological conditions, is attracting more and more attention. Although experiments can explore chemical process of CO2 sequestration, it is limited in time scale. CO2 geological storage will last...Read more

Development of Porous Carbon Nanomaterials from Petroleum Waste for CO2 Capture and Mineralization
(Corresponding) Jalilov A., Albaiz A., Alsaidan M.
Topic:
Solid waste management
Herein we report on developing mineral
carbonization technology using porous carbons from
vacuum residue to generate products that are best
suited economically for CO2 sequestration.
Activating of vacuum residue using activation
reagent as Ca(OH)2 and MgO mixed with KOH gives
a porous...Read more

A comparative analysis between EU MRV and IMO DCS – the need to adopt a harmonised regulatory system
(Corresponding) Boviatsis M., Tselentis B.
Topic:
Environmental impact of maritime transport
This paper analyses and compares the two methods proposed for monitoring, reporting and verifying CO2 emissions from shipping, namely the European Union MRV Regulation (EU 2015/757) and the Global Data Collection System of the IMO for fuel oil consumption of ships adopted as an amendment to MARPOL...Read more
Keywords:
CO2 emissions, EU MRV, IMO DCS, MARPOL Annex VI, fuel consumption
Upgrading from biogas to biomethane is currently growing in Europe for economical and sustainable aspects. To date different treatments are proposed to upgrade biogas to a higher fuel standard. Among these, physico-chemical treatments are spreading widely in the biogas technology market...Read more
Performance evaluation of flue gas cured calcium rich fly ash based building blocks
(Corresponding) Usta M., Adegbile M., Gregor A., Paaver P., Hain T., Yoruk C., Uibu M., Trikkel A.
Topic:
Mineral carbonation of alkaline waste materials
This work focuses on the local alkaline wastes of Estonia where different waste streams were studied for the performance testing of the fly ash based building blocks. Fly ash from oil shale direct combustion and wood fly ash from district heating plant were considered in the applications for...Read more

Is Greece greener than the data shows? Calculation of Green GDP and comparison with neighboring countries
(Corresponding) Stjepanović S., Škare M., Tomić D.
Topic:
Environmental data analysis and modelling
Is Greece greener than the current economic indicators show? GDP is used as the leading economic indicator of economic growth and progress. GDP as a measure, among other things, lacks an environmental component. In this paper, we have developed a Green GDP for Greece and neighboring countries and...Read more

Chemical weathering rates and CO2 consumption in the Savuto basin (Sila Massif, Italy) inferred from riverine water chemistry
(Corresponding) Fuoco I., De Rosa R., Timpano A., Cundari F., Apollaro C.
Topic:
River systems in diverse climates and environments
The aim of this work was to estimate the silicates (SWR) and carbonates (CWR) weathering rates as well as the CO2 consumption in the Savuto basin (Sila Massif, Southern Italy), studying the riverine water chemistry. Six sampling sites were investigated. Starting from the rain composition,...Read more
