Removal of gaseous ammonia released from odorous composting leachate employing carbonaceous adsorbents prepared from agro-industrial wastes
PERDIGÃO-LIMA T., Feliciano M., Pereira Wilken A., Gomes H., Shinibekova A., Kalmakhanova M., Massalimova B., (Corresponding) Diaz de Tuesta J.
Topic:
Environmental odour, monitoring and control
Biological and composting processes used in the treatment of municipal solid waste typically are sources of odour pollution (gaseous pollutants include SO2, NH3, H2S and other toxic air pollutants). In this work, the removal of NH3 present in odorous composting leachate was assessed for the first...Read more
Production of added-value metabolites during growth of wild-type yeast strains on media composed of biodiesel-derived crude glycerol
Diamantopoulou P., Filippousi R., Sarantou S., Stoforos N., Xenopoulos E., (Corresponding) Papanikolaou S.
Topic:
Environmental biotechnology and bioenergy
Wild-type yeast strains of Metschnikowia sp., Rhodotorula sp. and Rhodosporidium sp. were grown under nitrogen-limited conditions with crude glycerol employed as sole substrate in shake flasks, under nitrogen-limited conditions, with initial glycerol concentration (Glol0) ≈45 g/L. Yeasts presented...Read more
Assessment of particulate pollution in a medium sized Greek city - the effect of biomass burning and COVID-19 lockdown
(Corresponding) Diamanti V., Triantafyllou A., Garas S.
Topic:
Air pollution
Airborne particulate matter (PM) with an aerodynamic diameter of 10μm or less has severe negative effects on human health. In many European urban environments, small residential heating appliances contribute significantly to the degradation of air quality by generating a substantial quantity of PM...Read more

Designing sustainable processes for the valorization of industrial and environmental waste streams towards industrializable polyhydroxyalkanoates
(Corresponding) Ntaikou I., Antonopoulou G., Kokkinopoulou I., Ladakis D., Tragoulias K., Zhang Y., Yan Q., Nan J., Pissaridi K., Spiliotis V., Ladikos D., Moutsatsou P., Koutinas A., Lyberatos G.
Topic:
Bioplastics
In the present study different environmental and industrial waste streams are assessed as feedstock for the production of bioplastics adequate to be used for food packaging applications or for the formation of fully biodegradable garbage bags. For the production of bioplastics i.e...Read more
New solutions for a better and sustainable agriculture
The emergence of the bioeconomy and the concept of sustainability in production processes have been essential for the protection of the environment and biodiversity, as well as for the implementation of processes for energy recovery, the creation of new jobs and increased competitiveness...Read more

Biorefinery model for the production of biofuels and bioproducts from lignocellulosic biomass
Vela-García N., (Corresponding) Bolonio D., J. Chuck C., García-Martínez M.
Topic:
Environmental biotechnology and bioenergy
This work studies advanced biofuel and biomaterials production using lignocellulosic biomass from poplar crops. In this sense, lignocellulosic biomass transformation into biojet fuel, bioLPG, green diesel and High-Density Polyethylene (HPDE) was studied through an exhaustive evaluation, including a...Read more
Black Carbon characterization with Raman spectroscopy and machine learning techniques: first results for urban and rural area
(Corresponding) Drudi L., Giardino M., Janner D., Pognant F., Matera F., Sacco M., Bellopede R.
Topic:
Air pollution
Among the chemical substances of Particulate Matter (PM), there is a considerable quantity of black carbon (BC), which is linked to adverse public health effects and climate change. This study aims to develop an innovative method for the source apportionment of BC inside the PM, using Raman...Read more

Biogas Desulfurization by Pelletized Biomass Ash in a Fixed Bed Arrangement
(Corresponding) Lapp F., Brück F., Liebich T., Lang M., Theilen U., Weigand H.
Topic:
Gas emissions control and utilization
The removal of H2S is a prerequisite to the energetic valorization of biogas in combined heat and power (CHP) plants. Conventionally, the final step in desul-furization involves filtration over granular activated carbon (GAC). Rising market prices for GAC have fostered research on alternative...Read more

UTILIZATION OF AGRICULTURAL AND URBAN PLASTIC WASTE REVIEW: INTRODUCTION TO PYROLISIS AND HYDROCARBON REFORMATION
KOUMPAKIS D., (Corresponding) VLACHOKOSTAS C.
Topic:
Waste-to-energy
Agricultural and urban waste consist of large quantities of biomass and petroleum originated waste. These two categories are rich in hydrocarbons which can be utilized again after their first life cycle. Pyrolysis is a thermochemical process in which solid hydrocarbons decompose in conditions of...Read more
