Biogas production from sunflower residues: effect of pretreatment
(Corresponding) Stamatelatou K., Spyridonidis A., Zhurka M., Vasiliadou I., Lytra V.
Topic:
Biowaste
Sunflower residues are a prominent substrate of renewable source for biogas production during anaerobic digestion (AD). However, due to its recalcitrant structure, pretreatment is necessary to increase its biodegradability. The objective of the present work was to evaluate the effect of the NaOH...Read more
Early-stage LCA of a novel fuel flexible CHP technology based on biomass gasification and a SOFC
Moretti C., Rühlin V., (Corresponding) Corona B.
Topic:
Life cycle analysis (lca)
To mitigate climate change and reduce the consumption of fossil fuels, more efficient energy production is necessary. Combined heat and power systems (CHPs) are a key technology to reach such an objective, due to its higher energy efficiency than the separate production of heat and electricity...Read more
Biomass burning tracers in urban and rural particles in Silesia - Poland
(Corresponding) Czaplicka M., Janoszka K.
Topic:
Air pollution
The major tracers are thermal degradation products from the biopolymer cellulose, namely the didehydromonosaccharide derivatives levoglucosan (LG), galactosan (GL) and mannosan (MN) and the resin acid derivative dehydroabietic acid, with minor β-sitosterol. The relative proportions of levoglucosan...Read more
Biotreatment of Brewery Wastewater Using the Filamentous Cyanobacterium Leptolyngbya sp.
Papadopoulos K., Economou C., Moustaka-Gouni M., Tekerlekopoulou A., Aggelis G., (Corresponding) Vayenas D.
Topic:
Wastewater treatment
Brewery wastewater is generated from the beer brewing process in large amounts (4-8 m3 per m3 of beer produced). Brewery wastewater consists of high organic matter content, significant nitrogen and phosphorus concentrations and easily biodegraded compounds. Even though most biological treatment...Read more
Life cycle assessment of the use of biomass as energy source in Northern Greece
Dounavis A., Karamanos L., Lekkas D., (Corresponding) Klontza E.
Topic:
Life cycle analysis (lca)
Decrease of fossil fuel consumption in the energy sector is an important step towards more sustainable energy production. On the other hand, domestic and imported biomass or biofuels which are used as energy sources play an important role in many future energy scenarios and national policies...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

Pyrolysis of Spirulina sp. Microalgae: Effect of Temperature on Chemical Compositions of Bio-Oil and Aqueous Phase
(Corresponding) Özçakır G., Karaduman A.
Topic:
Environmental biotechnology and bioenergy
Pyrolysis of Spirulina sp. Microalgae was carried out in a semi-batch glass reactor system. Effect of temperature on the yields of pyrolytic products (gaseous, liquid and solid residue) and chemical composition of the liquid products were investigated. All experiments were performed in 25 mL/min...Read more
OMCEC: A Novel Method for Simultaneous Detection of Composition, Geometry and Motion of Suspended Particles
(Corresponding) Nguyen T., Tang F., Maggi F.
Topic:
Microplastics in the marine environment
Here, we introduce OMCEC, a laboratory-based system that simultaneously measures the material composition, geometric properties, and motion of individual suspended aggregates in a non-invasive and non-destructive way. OMCEC consists of a full-color high-resolution optical system and real-time...Read more
The cultivation of Penicillium strain, isolated from rotten vegetables, on potatoe dextrose broth (PDB) medium enriched in arginine and mineral elements, allowed to obtain a yield of 31.7 mg/g of dry biomass and 9 mg/g of dry biomass into chitin and natural chitosan, respectively. The infrared...Read more

Fungal biomass, chitin, natural chitosan, Penicillium, composition of the medium.
Volatile Organic Compounds (VOCs) are toxic for the environment and human health and their tendency to readily volatilize in the atmosphere leads to problems connected to odours annoyance. The conventional treatments for VOCs gaseous emissions conventionally entail the application of chemical-...Read more
