Application of quorum quenching to improve performance of membrane bioreactors: A comprehensive mini-review
(Corresponding) Banti D., Kampouris I., Yiangou M., (Corresponding) Samaras P.
Topic:
Wastewater treatment
Membrane bioreactors (MBRs) have been widely used for wastewater treatment, presenting however a major disadvantage, the membrane fouling problem. The sludge microorganisms produce soluble microbial products (SMP) and extracellular polymeric substances (EPS) that lead to a formation of a sticky...Read more

GMO POLICIES FOR ENVIRONMENTAL PROTECTION IN THE ERA OF GENOME EDITING
(Corresponding) Argyropoulos D., Psallida C.
Topic:
Biodibersity conservation
In recent years, immediate human interference with nucleic acid sequences has resulted in what is popularly known as Genetically Modified Organisms (GMOs). The process, based on molecular technologies under the term genetic engineering, has added new information to the existing pool of genetic...Read more
Histopathological alteration in gills and liver of Cyprinus Carpio after a short-term exposure to titanium dioxide nanoparticles
(Corresponding) Iftikhar N., Hashmi I.
Topic:
Ecological effects of environmental change
With the rapid development of nanotechnology in past few decades, engineered nanomaterials (ENMs) have been extensively used in variety of domestic, commercial, and industrial products. Nano-titanium dioxide is one of the most widely used nano-material due to its UV light absorption, optical...Read more

ANALYTICAL DEVELOPMENTS FOR PVC RADIOOXIDATION STUDY, IN SIMULATED DISPOSAL CONDITIONS
(Corresponding) Chantreux M., Rossignol S., Ricard D., Bussière P., Therias S., Gardette J., Wong-Wah-Chung P.
Topic:
Hazardous waste management
Radioactive waste is generated by the use of radioactive materials in industry, research and medicine, as well as in nuclear power plant. The management and disposal of such waste is, therefore, a very important issue. In France, the estimated volume for the low intermediate-level long-lived...Read more
Assessment of yields and properties of bioplastics production from acidified sugary wastewaters via mixed microbial cultures
Kora E., Tsaousis P., Andrikopoulos K., Chasapis C., (Corresponding) Ntaikou I., Voyiatzis G., Lyberatos G.
Topic:
Bioplastics
A mixed microbial culture (MMC) of poly-hydroxy-alkanoates (PHAs) producers was developed in a draw- fill reactor (DFR) subjected to sequential nitrogen/carbon limitation stress using short chain fatty acids (SCFAs) as carbon source. The distribution of microorganisms was analyzed in the beginning...Read more
SUITABLE PRACTICES OF DESIGN AND REPAIRMENT FOR REDUCING THE ENVIRONMENTAL IMPACT OF SMARTPHONES
(Corresponding) Perula A.
Topic:
Life cycle analysis (lca)
Nowadays, smartphones are one of the most common devices in developed countries, as most citizens are owners of at least one. However, smartphone’s average lifetime is reported to be between 2 and 3 years by many studies, and the environmental impact of manufacturing, using and disposing of these...Read more

Production parameters and nutritional value of Pleurotus ostreatus mushroom cultivated on agricultural wastes
Melanouri I., Fourtaka K., Papanikolaou S., (Corresponding) Diamantopoulou P.
Topic:
Agroforestry, forest and agricultural sustainability
The influence of two alternative agro-residues (barley and oat straw-ΒΟ and beech wood residues-ΒW) used as main cultivation substrates in respect to wheat straw-WS was examined on the production and quality characteristics of Pleurotus ostreatus, strain AMRL 144. Evaluation included fungal bio-...Read more
Activated carbon-polyethyleneimine-alginate composite fiber for scavenging pharmaceuticals with different charges from aqueous solutions
Dangi Y., Choi J., Lim C., Song M., Han M., Lin X., (Corresponding) Yun Y.
Topic:
Water treatment
Activated carbon (AC) is a potential adsorbent for water purification, though it is difficult to separate after use. To solve this problem, for the first time, the ternary composite fiber (ACPEIA) of AC, polyethyleneimine (PEI), and alginate (A) was fabricated as a multifunctional adsorbent for...Read more
Reductive Debromination of 1,2-dibromoethane and tribromoethylene by a Shrimp-Shell Biochar and Green Rust Composite
(Corresponding) Lindhardt J., Holm P., Lu C., Hansen H.
Topic:
Soil and groundwater contamination and remediation
Simple brominated ethanes and ethylenes like 1,2-dibromoethane (DBA) and tribromoethylene (TrBE) are widespread, toxic contaminants and able to persist in soil and groundwater. Some of these compounds are used as intermediates in the production of resins and as wood preservatives. Previous uses...Read more
Integrating Ecosystem Services (E.S.) in spatial planning: a literature review
Pozoukidou G., Papageorgiou M., (Corresponding) Kesisoglou D.
Topic:
Spatial environmental planning
Integration of ES in spatial planning constitutes a critical issue in the context of establishing resilient and sustainable policies. In this paper, a literature review was performed, to evaluate the integration of ES in spatial planning practices through institutional and governmental planning...Read more
