High-rate anaerobic co-digestion of agro-industrial wastes combined with ammonia recovery and biogas purification
Eftaxias A., Georgiou D., (Corresponding) Diamantis V., Koumara A., Koskinari M., Aivasidis A.
Topic:
Environmental biotechnology and bioenergy
Screened dairy manure, pressure-sterilized animal by-products, and cheese whey were co-digested in a Plug Flow Reactor (PFR) over a period of 150 days. The mixture was characterized by TCOD = 70±8 g/L, SCOD = 26±6 g/L, NH4-N = 1.5±0.3 g/L, TSS = 20±5 g/L, VSS = 18±6 g/L, TS = 33±5 g/L, VS = 26±2 g/...Read more
Thermo-physical properties of agricultural residues for syn gas production using thermo-gravimetric analysis
(Corresponding) kumar p.
Topic:
Energy technologies and sustainability
The thermal degradation behaviour and the activation energy can be integrated utilized to understand the behaviour and constituent of biomass degradation rate prior to gasification. Thermophysical properties of agricultural residues in order to facilitate its further processing and utilization for...Read more
Thermolysis and kinetic parameters determination of biomass fuel powders by differential thermal gravimetric analysis (TGA/DTG/DTA)
(Corresponding) KUMAR p.
Topic:
Environmental biotechnology and bioenergy
The kinetics of the thermal decomposition of the agriculture residues were evaluated using a differential thermo-gravimetric analyser under a non-isothermal condition. The direct Arrhenius plot method and the integral method were applied for the determination of kinetic parameters: activation...Read more

Sources and transfer of Cu, Hg and Pb into marine food webs using innovative tracers (metal stable isotopes, trophic markers): results of a pilot study in a French coastal area
(Corresponding) Chouvelon T., Araujo D., Bouchoucha M., Briant N., Bruzac S., Crochet S., Knoery J., Ponzevera E., Rozuel E., Sireau T., Thomas B., Amouroux D., Bérail S., Brach-Papa C.
Topic:
Heavy metals in the environment
Copper (Cu), mercury (Hg) and lead (Pb) are elements and contaminants of historical and emerging concerns in coastal environments. Although Cu is considered essential for living organisms, it is bioactive in a narrow range of optimal concentrations. Hg and Pb have no known biological role and are...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

Quantification of Soil Properties from Hyperspectral Data for Sustainable Agriculture Using Deep Learning
(Corresponding) Singh S., Kasana S.
Topic:
Agroforestry, forest and agricultural sustainability
The characterization of soil properties is critical for optimizing farming for sustainable agriculture. All the existing techniques for soil quantification do not take advantage of the sequential nature of Hyperspectral Data. This work focuses on proposing a Hybrid Framework that can quantitatively...Read more
Estimation of Soil Organic Carbon for Sustainable Agriculture using Deep Learning
(Corresponding) Singh S., Kasana S.
Topic:
Agroforestry, forest and agricultural sustainability
The organic carbon percentage is concomitant indicating the mineralization of nutrients and the ability of the soil to hold nutrients cations, structural stability, and water holding capacity. It is necessary to know the quantity of carbon for healthy soil and avoid the production related problems...Read more

Evaluation of soil loaded with green iron nanoparticles for hexavalent chromium reduction
(Corresponding) Mystrioti C., Mpouras A., Papassiopi N., Dermatas D.
Topic:
Nanomaterials in the environmnents applications and effects
Chromate is a pollutant often found in groundwater and considered a serious threat for humans and ecosystem. Iron nanoparticles produced by green tea polyphenols (GT-nZVI) is a powerful reductant, appropriate for the reduction of Cr(VI) to Cr(III). GT-nZVI suspension was initially conceived ideal...Read more

O-fire+: a pioneer solution on wildfire incident planning and response for enhancing the resilience of individual infrastructures
(Corresponding) Karystinakis K., Partozis T., Grigoriadis D., Mantzavelas A., Diamantopoulos S.
Topic:
Disaster risk reduction and management
Wildland fires can seriously affect infrastructures causing extended direct or indirect financial losses, as well as societies causing the loss of properties, landscape quality and even human lives. The relevant management requires effective planning prior and quick/targeted response during those...Read more
Evaluation of calcium polysulfide as a reducing agent for the restoration of a Cr(VI)-contaminated aquifer
(Corresponding) MPOURAS T., PAPASSIOPI N., LAGKOUVARDOS K., MYSTRIOTI C., DERMATAS D.
Topic:
Efficient water resources management in cr(vi) impacted water bodies
This work aims at investigating the efficiency of applying calcium polysulfide (CPS) as a reducing agent for the decontamination of a heavily Cr(VI)-contaminated aquifer. Series of batch experiments were carried out in order to evaluate the reductive behavior of CPS towards the aqueous and solid...Read more
