Use of Biochemical Methane Potential (BMP) Assays for predicting biogas production from co-digestion of food waste and compostable bags

Kattamis S., (Corresponding) Maragkaki A., Papastefanakis N., Sampathianakis I., Lolos T., Tsobanidis C., Velonia K., Manios T.
Topic: 
Solid waste management
Biodegradable plastics have been introduced to the market to substitute petro-based plastics to alleviate plastic pollution. Biochemical methane potential tests were carried out on food wastes (FW), with or without pre-treatment, compostable bag and a mixture of food waste and compostable bag (CB)...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

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

Enhanced commercial and 3D-printed bio-carriers improve wastewater treatment performance: A critical mini-review

(Corresponding) BANTI D., SAMARAS P.
Topic: 
Wastewater treatment
An advanced wastewater treatment technology, simple, uniform, reliable and stable in its operation, which at the same time is highly competitive from the economic and environmental point of view, is Moving Bed Biofilm Reactors (MBBR) performed with the contribution of bio-carriers. This review...Read more

Flood modelling using a combined 1D/2D model: the case of the 2017 flash flood in Mandra, Greece

(Corresponding) Mitsopoulos G., Bloutsos A., Diakakis M., Panagiotatou E., Lekkas E., Baltas E., Stamou A.
Topic: 
Climpact: national network for climate change and its impacts
The design of an efficient Early Warning System for floods in a specific region requires the knowledge of the hydrodynamic behavior of floods that affects flood arrival times and thus the available warning times. In the present work, we attempt to answer the following research question “Is a...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

Biogas upgrade via ex-situ technologies

Spyridonidis A., Vasiliadou I., (Corresponding) Stamatelatou K.
Topic: 
Environmental biotechnology and bioenergy
The biological upgrade of biogas to biomethane (CH4 > 90%) is a popular emerging technology, since the produced CO2 is not removed but is converted to biomethane using hydrogen (H2). The initial aim of the present study is the acclimatization of a microbial population derived from a typical...Read more

CIRC4FooD: An urban food production system inspired by the circular economy

(Corresponding) Tsatsou A., Ioannides C., Noutsopoulos C., Tsimiklis G., Chrisomallos G., Tsiropoulos Z., Mamais D., Malamis S.
Topic: 
Spatial environmental planning
The environmental footprint of the current, linear food system is a key challenge that must be faced for a global transition to sustainability. Agricultural practices are drivers of polluting food production, while cities form critical hubs of wasteful food consumption. In this context, urban...Read more

Determination of atmospheric amines in boreal forest using unmanned aerial drone with an integrated miniaturized air sampling system

Pusfitasari E., Ruiz-Jimenez J., Heiskanen I., Jussila M., Hartonen K., (Corresponding) Riekkola M.
Topic: 
Atmospheric chemistry and physics
Amines are ubiquitous in the atmosphere and their presence is considered important especially due to their hazard to human health and their contribution to new particle formation that can affect climate change. In this study, tailor-made mesoporous functionalized silica sorbents were used in in-...Read more
