The use of recycled human food wastes and unconsumed leftovers in the aquaculture industry for the partial replacement of commercial manufactured fishmeal-based feeds as a more sustainable and environmentally friendly practice: Recent research and finding
(Corresponding) Petsas A., Vagi M.
Topic:
Food waste
Food waste or leftovers generated by various raw or processed food materials that are not consumed but instead are usually disposed to waste landfills are regarded as a global issue which impacts human health and environmental sustainability. An enormous pressure in disposing of food wastes in...Read more
Adsorption technology in waste water treatment processes utilizing activated carbons as adsorbent materials prepared from waste tires: Recent research and trends in the removal of various toxic and persistent organic pollutants
(Corresponding) Vagi M., Petsas A.
Topic:
Green chemistry
Various toxic contaminants when are present in the environment pose a threat to the inhabitants of natural ecosystems owing to their non-biodegradable nature that increases their high toxicity towards non-target organisms. The large mass of solid wastes that are generated from waste rubber tires...Read more
Development and promotion of the WEEE prevention culture in Greece
(Corresponding) Charitopoulou T., Vogiatzidaki E., Gkitzeni I., Malliaris M.
Topic:
Electric and electronic waste
WEEE streams challenge the goals towards a circular economy, since WEEE contain valuable and scarce resources that could be prepared for a second life or recovered. In the framework of the project LIFE REWEEE (LIFE14 ENV/GR/000858), Hellenic Recycling Agency (HRA) aims to raise awareness among...Read more

Identification and Quantification of Microplastic in Sewage systems by TED-GC-MS
(Corresponding) Altmann K., Goedecke C., Bannick C., Abusafia A., Scheid C., Steinmetz H., Braun U.
Topic:
Microplastics in the marine environment
Over the last years, the number of publications reporting the amount of microplastic (MP) all over the world increased rapidly. But harmonised sampling, sample preparation and analysis strategies are missing. Commonly used methods are very time consuming and not comparable to each other. Hence,...Read more

Extraction of Oil from Spent Grounds Coffee using Ultrasound as Pre-Extraction Method
(Corresponding) Cubas A., Hermmann K., Bianchet R., Moecke E.
Topic:
Food waste
The treatment and processing of coffee annually produces a large volume of biological waste, which contributes to environmental pollution, it is estimated that coffee production generates approx. 6 million tonnes of spent coffee grounds per year in the world (GETACHEW and CHUN, 2017). Thus, the...Read more

Valorisation of waste polyethylene by blending with ethylene-vinyl acetate and incorporation of a new type of compatibilizer
(Corresponding) Simon-Stőger L., Varga C.
Topic:
Solid waste management
Nowadays polyethylene is one of the polymers produced in the greatest volume, therefore, parallelly the amount of generated waste polyethylene (w-HDPE) significant as well. Valorisation and recycling of w-HDPE can be realized by blending with different types of polymers and/or elastomers in order...Read more
Innovative methods of ground improvement for problematic transport earthwork materials
(Corresponding) Mavroulidou M., Safdar M., Gunn M., Gray C., Payne I., Garelick J., Purchase D.
Topic:
Environmental management and policies
The paper focuses on emerging (bio-) chemical techniques used to improve engineering properties of two problematic earthwork materials of the UK rail network to address transport earthwork infrastructure resilience in view of climate change. Studied techniques include novel cementing agents (e.g...Read more
Statistical prediction models for the odour emissions quantification in terms of odour concentration: Analysis and comparison
(Corresponding) Galang M., Ballesteros Jr. F., Zarra T., Naddeo V., Belgiorno V.
Topic:
Environmental odour, monitoring and control
Measuring odour concentration is a significant step to achieve efficient environmental odour management in continuous, objective and repeatable manner. To deal with this, researchers developed instrumental odour monitoring systems (IOMS) by applying odour monitoring models (OMM) for prediction. At...Read more

Topic:
Heavy metals in the environment
Lignite mining in the Oropos Neogene basin (North Attica), especially in the areas of Milesi and Markopoulo, operated since last century and ceased in the late 1960’s. Piles of complex waste material consisting of lignite tailings and waste rocks are dispersed in the area between the above...Read more
