Hydrogen production from cotton wastes by mean of dark fermentation
(Corresponding) Sołowski G., Konkol I., Shalaby M., (Corresponding) Cenian A.
Topic:
Energy technologies and sustainability
Dark fermentation of textile wastes is discussed in the paper. In the experiment were used cotton wastes. Before fermentation the cotton was hydrolyzed using 0.1 M of HCl. The inoculum was pretreated using heat shocked for 0.5 h at temperature of 105°C. The fermentation was carried out under...Read more
The influence of methane emission and hard coal production on air quality and greenhouse effect in 1994-2017 in the Upper Silesian Coal Basin (Poland)
(Corresponding) Dreger M.
Topic:
Air pollution
The Upper Silesian Coal Basin (USCB) is the largest coal basin in Poland and one of the largest in Europe. It is the most industrialized region in Poland. The main natural resource and energy raw material is hard coal which was produced by 65 mines in the early nineties. The USCB geology is very...Read more

Hydrothermal pretreatment optimization for enhanced anaerobic digestion of willow sawdust
ALEXANDROPOULOU M., PAPADOPOULOU K., (Corresponding) ANTONOPOULOU G., LYBERATOS G.
Topic:
Solid waste management
Lignocellulosic biomass including agricultural and forestry residues such as willow sawdust could be used as feedstock for anaerobic digestion (AD). Hydrolysis has been shown to be the rate-limiting step in the case of AD of such substrates. Although being abundant, since the annual world...Read more
The limitation of the methane (CH4) emission in the Upper Silesian Coal Basin as a result of the Polish Mining Group closing program.
Dreger M.
Topic:
Air pollution
Hard coal mining is responsible for 9% of the worldwide methane emission to the atmosphere. Methane is the second strongest greenhouse gas after carbon dioxide, but its radiative power is 25-30 times stronger than the radiative power of CO2 .In the Polish reality, hard coal mining is one of the...Read more

Can the seasonal variability affect the BMP of fruit and vegetable waste?
(Corresponding) Scotto di Perta E., Lamboglia R., Cesaro A., Frunzo L., Esposito G., Papirio S.
Topic:
Food waste
Fruit and vegetable waste (FVW), largely produced in open markets, is characterized by highly putrescible materials, thus being a proper substrate for anaerobic digestion. This study investigated the effect of the seasonal variation of FVW, on the biochemical methane potential (BMP). To this end,...Read more

Anaerobic Digestion of Municipal Wastewater (MWW) in a Periodic Anaerobic Baffled Reactor (PABR)
Zarkaliou A., Kougias C., (Corresponding) Papadopoulou K., Lyberatos G.
Topic:
Wastewater treatment
The scope of this work is to study the treatment of municipal wastewater in a Periodic Anaerobic Baffled Reactor (PABR). PABR is an innovative, high-rate bioreactor, designed to operate under high organic loadings. Apart from the Hydraulic Retention Time (HRT) an important operational parameter is...Read more

Ground based integrated path differential absorption sensor for remote sensing of CO2, CH4 and H2O atmospheric greenhouse gases
(Corresponding) Panagiotis S., Psyllakis G., Samartzis P., Velegrakis M.
Topic:
Environmental odour, monitoring and control
An autonomous, ground-based, integrated path, differential absorption light detection (IPDA) system is presented, capable of measuring multiple gases concentration in the atmosphere. The device was developed to monitor small scale locations with high greenhouse gases emissions and is equipped with...Read more
A review on the potential use of flammable gases from sewage systems as a source of energy
(Corresponding) Ghaffari M., Paurine A., Ali S., Mavroulidou M.
Topic:
Energy technologies and sustainability
The demand for natural resources has increased exponentially due to the consistent growth of the global population and urbanization. This has resulted to considerable environmental challenges that are potentially affecting the global sustainable development goals. Therefore, it is important to...Read more
The effect of HRT in the successful bioaugmentation of CSTRs working under ammonia toxicity
Tzenos C., Christou M., Kalamaras S., (Corresponding) Kotsopoulos T.
Topic:
Environmental biotechnology and bioenergy
High levels of ammonia is a common inhibitory factor in anaerobic digestion (AD) resulting in low methane production and unbalance of the process. In the present study, the adjustment of the hydraulic retention time (HRT) and the bioaugmentation process (BP) are investigated to counter the negative...Read more
Methane distribution over Greece as derived from Sentinel-5P TROPOMI data
EVANGELOU I., GIALESAKIS N., DASKALAKIS N., (Corresponding) KANAKIDOU M.
Topic:
Climpact: national network for climate change and its impacts
Global warming, induced mainly by greenhouse gases emitted by human activities, is an environmental issue of crucial importance for society. Greenhouse gases, such as methane (CH4), need to be monitored and their anthropogenic emissions quantified in order to be reduced. We here present, the first...Read more
