One step industrial enzymatic technology of starch hydrolysis to glucose
(Corresponding) Kvesitadze G., Khvedelidze R., (Corresponding) Urushadze T., Kutateladze L., Zakariashvili N., Jobava M., Sadunishvili T.
Topic:
Energy technologies and sustainability
Starch degrading enzymes like amylase have received great attention because of their technological significance and economic benefits. As a result of screening of Durmishidze Institute of Biochemistry and Biotechnology collection of mycelial fungi, accounting 2500 individual strains, 39 strains...Read more
Analysis of the content of germanium, tellurium and thallium in the grounded waste of electronic equipment
(Corresponding) Fornalczyk A., Willner J., Jablonska-Czapla M., Rachwal M.
Topic:
Hazardous waste management
The article draws attention to the problem of the presence in waste electrical, electronic equipment (WEEE) of selected metals from the group of critical metals (germanium), strategic metals (tellurium) and highly toxic elements (thallium). Due to low content of these metals in e-waste, they are...Read more
Technology Critical Elements in industrial wastes as the source of soil contamination
Rachwal M., Jablonska-Czapla M., Grygoyć K., (Corresponding) Fornalczyk A., Willner J.
Topic:
Soil and groundwater contamination and remediation
The intensive development of industry, especially the mining and metallurgy, automotive and electrical industries, as well as the growing demand, rapid consumption and "ageing" of most products, including electrical/electronic equipment, requiring regular replacement, affects the amount...Read more

Anaerobic MBR technology for treating municipal wastewater at ambient temperatures
(Corresponding) Plevri A., Mamais D., Noutsopoulos C.
Topic:
Wastewater treatment
An innovative way to treat municipal wastewater and produce energy at the same time is anaerobic treatment. Anaerobic processes are traditionally used for high-strength wastewater or municipal sludge treatment and only recently have been applied for the treatment of low strength municipal...Read more
Synthesis of Fe3O4-Ag Nanocomposite and Their Performance as Surface Modifiers for TiO2 Membranes in Treating Oily Wastewater
Aboulella A., Wadi V., Naddeo V., Banat F., (Corresponding) Hasan S.
Topic:
Water treatment
Membrane technology has shown extraordinary performance in treating oily wastewater. Yet, more research is focused towards enhancing the performance of the separation process. In this work, Fe3O4-Ag composite nanoparticles (NPs) were synthesized using the co-precipitation technique and applied on...Read more
Electro-bioremediation of nitrate contaminated saline groundwater
(Corresponding) Puggioni G., Carucci A., Dessì E., Pous N., Puig S., Unali V., Milia S.
Topic:
Water treatment
Sustainable exploitation of coastal aquifers is often hindered by the presence of contaminants and high salinity levels. This study proves for the first time the electro-bioremediation of nitrate contaminated saline groundwater. Two 3-chamber bioelectrochemical systems (BES) were operated in...Read more
Abuhasheesh Y., Hegab H., Wadi V., Naddeo V., AlMarzooqi F., Banat F., Aljundi I., (Corresponding) Hasan S.
Topic:
Water and wastewater treatment and reuse
The limited access to clean water sources and the severe consequences of oil spills on the environment are of significant concern. Membrane technology showed superior performance to the other conventional techniques due to its higher performance, lower cost, ability to separate emulsions, and being...Read more
Comparative evaluation of three different membranes for the treatment of a brewery and a dairy treatment effluent
(Corresponding) Plevri A., Gkoumas F., Koumaki E., Noutsopoulos C., Mamais D., Nikolaou M., Magraritis M., Malamis S.
Topic:
Circular economy and industrial symbiosis
A laboratory-scale system with a capacity of 7L/h consisting of three different ultrafiltration membranes operating alternatively, was designed and installed at the Sanitary Engineering Laboratory (SEL) facilities. The purpose of this membrane system was to test the performance of alternative...Read more
Circular Cities: Challenges and Opportunities towards their transition to a green, smart and circular economy.
Liogkas V.
Topic:
ESG (Environmental, Social and Governance) and circular economy
Cities cover 3% of the land on Earth, however with more than 70% of the population expected to live in urban areas by 2050 they drive almost three-quarters of GHG emissions. They account for two-thirds of global energy demand, consume 60-80% of natural resources and generate 50% of waste.
Urban...Read more
