[CEST2019_00053] Assessment of Concrete Footpath Upheavals in Heatwaves
by Bradford M.

Most concrete footpaths are cast without steel reinforcement and in segments between bituminous joints, with the joints intended to accommodate thermal expansions of the pavement. However, a combination of prolonged heatwave conditions and the ingress over time of material into the joints produces a situation in which the thermal movements are not in the plane of the pavement, but instead the pavement experiences an upheaval buckle. Within a framework of global warming and heatwaves, assessments of the potential for such buckles which pose a risk to safety are essential.

[CEST2019_00063] Putting accelerated carbonation of bottom ash into practice: operation of a continuous-feed pilot scale reactor
by Schnabel K., Brück F., Mansfeldt T., Weigand H.

Bottom ash (BA) is the dominant residue from municipal solid waste or refuse-derived fuel incineration. Disposal costs chiefly depend on the leachability of trace metals and salts. The mobility of these constituents is classically minimized by ageing for several months. Ageing involves the oxidation of metals, dissolution and precipitation reactions, and most importantly, car-bonation of BA induced by the uptake of carbon dioxide. Enhanced exposure to carbon dioxide sources has been referred to as accelerated carbonation.

by Sušnik J., Masia S., Khoury M., Vamvakeridou-Lyroudia L., Brouwer F., Riegels N., Domingo X., Echeverria L., Evans B., Savić D.

There is growing interest in using serious games for a wide range of applications and in the water-energy-food/land-climate nexus, where interactions in one sector lead to impacts in other sectors. Much practice revolves around sectoral silos, with little consideration of wider impacts. Serious games could help erode these silos, fostering efforts towards holistic policy making, where impacts can be explored and assessed without real consequences.

The number of publications reporting the amount of microplastic (MP) all over the world increased rapidly. Methods used so far are very time consuming and not able to provide information on total contents. As harmonised sampling, sample preparation and analysis strategies are missing different studies can hardly be compared and quantitative data, including identification and mass contents of the polymers found, are missing. This leads to a lack of comprehensive understanding of MP occurrence, source and entry pathways into the environment.

by Cubas A.L.V., Machado M.M., Hermmann K., Bianchet R.T., Moecke E.H.S.

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 sludge becomes a residue equivalent to approximately 50% of the roasted coffee in the soluble coffee industry (PUJOL D. et al. 2013).

by Kalčikova G., Jemec Kokalj A., Marolt G., Žgajnar Gotvajn A.

When microplastics enter aquatic ecosystems they are submitted to environmental aging which change their properties. Especially colonization by microorganisms alter their properties in term of density and adsorption properties. Hence the aim of the study was to evaluate the adsorption and leaching properties of virgin and aged microplastics. Silver (in form of silver nitrate) was selected as a model metal used for adsorption study. Results showed that silver is quickly adsorbed on both types of microplastics while aged microplastics adsorbed significantly more silver than virgin ones.

by Wander L., Vianello A., Vollertsen J., Braun U., Paul A.

µ-FTIR spectroscopy is a widely used tech¬¬nique in microplastics research. It allows to simultane¬ously characterize the material of the small particles, fibers or fragments, and to specify their size distribution and shape. Modern detectors offer the possibility to perform two-dimensional imaging of the sample providing detailed information. However, data sets are often too large for manual evaluation calling for automated microplastic identification. Library search based on the comparison with known reference spectra has been proposed to solve this problem.

by Lilas T., Antoniou E., Kotrikla A., Vatistas A., Dagkinis I.

The main environmental impacts of aquaculture include eutrophication, chemical pollution and harm to sensitive marine ecosystems. At the same time, the required energy leads to high emissions of greenhouse gases. Offshore wind turbines are a sector of renewable energy that grows rapidly. Offshore wind turbines can be combined with aquaculture units to meet their energy needs, saving fuel and reducing their carbon footprint. However, there are many difficulties in installing aquaculture units in existing offshore wind parks (e.g. small water depth).

by Toskos T., Panagiotakis I.,Dermatas D.

PFAS compounds are ubiquitous in the environment and in consumer products. Unlike other emergent contaminants this is a family of compounds with, literally, thousands members. Our knowledge of toxicological and environmental fate and transport properties is an evolving field. On the other hand, regulatory limits (when they exist) are extremely low and address only a limited handful of compounds. Because of their physical-chemical properties there are unconventional migration pathways, such as sewer exfiltration and biosolids residuals, that complicate site assessment and site closure.

We present a dynamic optimization model to explain the mechanism through which marine litter causes inefficiencies in the fishery sector. We study the dynamic properties of the model when the externality of marine litter is not taken into account and when it is internalized via the price of fish. We find that when the litter is internalized through the price of fish, the ocean quality is improved but fish catch decreases.

by Kaldellis J.K., Spyropoulos G., Kondili E.M., Triantafyllou A.G.

The utilization of electric vehicles (EVs) is considered as the new tool against the serious problems resulting from the oil products consumption in the transportation sector. In this context, the current work first estimates the real world electricity consumption of commercial EVs, including charging and discharging losses, using long term experimental measurements. Accordingly, on the basis of the total electricity consumption and using the electricity generation fuel mix (mainland vs. remote islands), the corresponding air pollutants are predicted.

by Hangyási K., Varga Cs., Nagy R., Simon-Stőger L.

Nowadays, beneficial management of plastic and rubber waste from different sources and environmentally friendly ways of recycling is becoming an increasing challenge. A possible solution for that problem could be to produce plastic composites usually consisting of heterogeneous phases. That fact and the interface between phases, and characteristics of components all play important roles in development of properties of end-product. By using a compatibilizing additive a chemical bridge can be created between the plastic composite components requiring reactive functional groups.

by Fornalczyk A., Willner J., Jablonska-Czapla M., Grygoyc K., Rachwal M.

The article draws attention to the problem of the presence of selected metals in waste electrical, electronic equipment (WEEE). These metals belong to 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 usually ignored during e-waste analysis, therefore they belong to the least-known metals in the literature regarding waste recycling. Their presence in WEEE can cause them to be concentrated in the environment during improper e-waste processing.

[CEST2019_00633] Water microbiota in a recirculating aquaculture system for environmental sustainability and fish welfare
by Almeida D., Sousa Z., Magalhães C., Silva E., Blanquet I., Mucha A.P.

Recirculating aquaculture systems (RAS) are a promising technology of fish production to reduce aquaculture environmental impact. Water recirculation relies on the stability of physical, chemical and biological processes to increase biosecurity. Although, disruptions in RAS systems can cause fish disease outbreaks by opportunistic pathogenic bacteria with an economic impact. The aim of this study was to characterize the water microbiota across the different sectors of a flatfish (Solea senegalensis) RAS unit, and understand its relation with the water quality parameters.

[CEST2019_00634] An innovative green iron-fertilizer, produced biotechnologically, for correcting iron chlorosis of soybean plants grown in calcareous soils
by Ferreira C., Lopez-Rayo S., Lucena J., Soares E., Soares H.

Iron deficiency is one of the main causes of chlorosis in plants, which leads to the loss in the field crops quality and yield. Iron-deficiency is a worldwide problem, particularly sever in calcareous soils (about 30% of world´s land surface). The current use of synthetic iron-chelates to prevent or correct iron-deficiency in plants raises environmental concerns due to their poor biodegradability. Thus, new, more environmentally-friendly efficient solutions are needed to solve iron deficiency-induced chlorosis (IDIC) in crops grown in calcareous soils.

by Kapellos G.E., Nagarajan M.B., Kalogerakis N., Doyle P.S.

Natural seeps and accidental releases of crude oil in the sea result in swarms of droplets that are carried away by underwater sea currents. The droplets may be created either at the sea surface during the breakup of an oil slick by sea waves, or at the seafloor during the extrusion of crude oil from natural cracks or broken wellheads. A high concentration of oil droplets in seawater disturbs the established ecosystem dynamics and poses a significant risk of toxic effects to fish and other marine animals.

As a driving force we use the fact that the volume of polyelectrolyte gel does depend on the surrounding salinity. While the salinity defines the gel volume in open system, i.e. in equilibrium with big aqueous solution bath, in closed system (in equilibrium with small bath) salinity is defined by the gel volume.

[CEST2019_00857] Mass and energy balances of sewage sludge pyrolysis in a lab rotary kiln
by Mendoza L., Gómez A., Rincón S.

The aim of this work is to study the influence of the main parameters of sewage pyrolysis in a rotary kiln on the product distriburion and energy balances. An indirectly heated rotary kiln at a laboratory scale was used (4 kg/h). An increase in the final temperature causes the reduction of the total condensable products and the non-condensable gas fraction increases. The residence time of the volatile phase has an important influence on the secondary reactions to increase the non-condensable gas with low tars content. These results contribute also a valuable input to perform LCA.

Agroforestry (AF) is a climate-smart agriculture (CSA) practice of deliberately integrating woody vegetation (trees or shrubs) with crop and/or animal systems to benefit from the resulting ecological and economic interactions. It is recognized as a proactive “negative emissions technologies” (Intergovernmental Panel on Climate change (IPCC) 1.5SR) that can foster sustainability in the current changing climate conditions. However, there are knowledge gaps to be filled regarding agroforestry, as well as bottlenecks and challenges.

Mixed pasture establishment is considered as a key point to increase livestock production due to the higher quality it has compared with unmanaged shrubby species. They also provide a set of ecosystem services such as carbon sequestration and higher biodiversity. Moreover, herbaceous pasture establishment effectively contributes to biomass production while replacing shrubs therefore reducing forest fire risk. Two of the main factors promoting the establishment of the herbaceous pasture are sowing and fertilisation.

by Brown F.R., Tarrant D.H., Gill R., Dhaliwal J., Sarala R., Patton S., Park J.S., Petreas M.

Dust is a good medium to assess indoor exposures to many persistent organics, including flame retardants. With concerns regarding persistence, bioaccumulation and toxicity of many flame retardants, a series of bans and regulations have created shifts in their usage. For firefighters, exposures to flame retardants on and off duty is a high concern. In 2018 we measured flame retardants in Canadian fire station dust and compared our findings with those of our 2015 US fire stations study. We used isotope dilution HRMS for PBDEs and GC-MS/MS for OPFRs.

by Hutton B., Norrish M., Horan E.

Landfill is generally believed to have higher greenhouse gas emissions than composting or waste-to-energy. The EU Landfill Directive requires nations to progressively divert biodegradable waste away from landfill. Waste disposal in landfill is at the bottom of its Waste Hierarchy. Many nations also ban landfilling of plastic. These policies may inadvertently increase global warming by increasing incineration. In Europe, Waste-to-Energy (WTE) incineration emits 72,000,000 tonnes of fossil CO2 a year, increasing yearly. Landfill methane is now generally captured.

by Boviatsis M., Tselentis B.

This paper analyses and compares the two methods proposed for monitoring, reporting and verifying CO2 emissions from shipping, namely the European Union MRV Regulation (EU 2015/757) and the Global Data Collection System of the IMO for fuel oil consumption of ships adopted as an amendment to MARPOL Annex VI in 2016. The two systems differ considerably in many aspects, such as, for example, the IMO DCS requires the reporting of ships' fuel consumption data, while the EU MRV involves the reporting of CO2 emission; the weight of cargo carried and energy efficiency.

[CEST2019_00926] A proactive international regulation system based on technological innovations against emerging environmental threats
by Boviatsis M., Alexopoulos A.B., Theodosiou M.

The adoption and enforcement of most conventions and regulations have been triggered by a series of disasters that had devastating effects on the marine environment. To improve the safety levels at sea and at the same time to protect the marine environment, it is imperative that the major shipping nations must ratify and make domestic law the international rules. Consequently, MARPOL, other conventions and codes refer to significant actions for minimising most pollution threats to the marine environment.

by Senatore V., Oliva G., Zarra T., Belgiorno V., Naddeo V.

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-physical processes, only promoting the transfer of the contaminants from gas to liquid and/or solid phases. Advanced Oxidation Process (AOPs) and biological processes, conversely, support the oxidation of the organic pollutants, promoting their conversion into harmless and odourless compounds.

by Abdullah H., Alshahri A., Fortunato L., Leiknes T.

In the Middle East, Harmful algal blooms (HABs) are considered a major contributor to membrane biofouling in Seawater Reverse Osmosis desalination plants. The presence of HABs in the raw feed water leads to the increase of membrane fouling rate, the increase of chemical consumption, leading to a temporary plant shutdown. Effective pretreatment can reduce the amount of organic foulants reaching the RO membrane and alleviate the problem of flux decline during RO operation and increasing the membrane lifetime.

Polycyclic aromatic hydrocarbons (PAHs) were investigated in surficial sediments collected from 39 stations in the open Aegean Sea, in order to assess their occurrence, distribution and major sources. Total PAH concentrations were generally low, comparable to those reported in relatively unpolluted marine areas. The highest values were recorded in the northern part Aegean Sea, which apparently receives more anthropogenic inputs both from continental runoff and atmospheric deposition. Several diagnostic criteria were used to investigate PAHs’ origin.

Mediterranean (MED) islands and coastal areas are under pressure due to water shortage. Water reserves are depleted, while tourism in the summer months burdens the limited water sources. A persistent issue arising from the above activity is the increased seasonal loads of sewage that wastewater treatment plants (WWTPs) receive and need to cope with. On the top of that, the circular economy concept is not implemented in the MED region and particularly in small WWTPs. Water, nutrients, energy and chemicals contained in sewage are not usually valorized.

Some of them have been studied in detail since 1980s and are already included in existing national or international legislative documents, while others are characterized as emerging contaminants (ECs) and no regulations currently require their environmental monitoring.

[CEST2019_00976] Mobilisation of Arsenic in groundwater, Lesvos Island, Greece
by Zkeri E., Aloypi M., Gaganis P.

In the present study, a geochemical analysis was conducted to investigate the As occurrence and release in groundwater from two different geological environments on Lesvos island: (i) the volcanic area of Mandamados (ignimbrite) and (ii) the metamorphic area of Tarti that comprises the geologic basement under ignimbrite. Seven sampling campaigns were conducted between October 2010 and October 2011 including 65 groundwater samples from 11 wells and springs. Chemical analyses showed As concentrations exceeding the 10 μg/L national drinking water limit in 46% of the samples from Mandamados.

[CEST2019_00977] Autonontarget: An R Package to Perform Automatic Non-Target Screening
by Aalizadeh R.,Thomaidis N.

Recent advances on Liquid Chromatography-High Resolution Mass Spectrometry (LC-HRMS) has revolutionized identification of new compounds, having various polarity, over various scientific fields especially in the environmental science. The continuous growing of LC-HRMS applications yet increased the “peak inventories”. This is achieved within three main workflows of “Target”, “Suspect” and “Non-target” screening. Although targeted analysis is the best way to confirm the identification of a compound, it is sometime not practical due to limited access to reference standards.

[CEST2019_00978] Immobilized rGO/TiO2 photocatalyst for water purification
by Zouzelka R., Brabec L., Remzova M., Rathousky J.

The preparation of immobilized graphene–based photocatalyst layers is highly desired for environmental applications. In this study, the preparation of an immobilized reduced graphene oxide (rGO)/TiO2 composite by electrophoretic deposition (EPD) was optimized. It enabled quantitative deposition without sintering and without the use of any dispersive additive. The presence of rGO had beneficial effects on the photocatalytic degradation of 4-chlorophenol in an aqueous solution. A marked increase in the photocatalytic degradation rate was observed, even at very low concentrations of rGO.

[CEST2019_00979] Influence of pH on the toxicity, uptake and biotransformation potential of citalopram in zebrafish (Danio rerio) embryos
by Damalas D.E., Panagopoulou E., Aalizadeh R., Schweızer M., Heıd C., Köhler H., Ohë P.V.D., Triebskorn R., Thomaidis N.S.

The contamination of the aquatic environment has raised concerns in the scientific community and regulatory authorities. Given the large number of xenobiotics, for most of them there is a striking deficit in the literature concerning their adverse effects on aquatic organisms. Citalopram (CTR) is a worldwide highly consumed antidepressant which has demonstrated incomplete removal by conventional wastewater treatment, hence resulting in the contamination of aquatic ecosystems. Consequently, it is urgent to evaluate its potentially toxic effects on aquatic organisms.

[CEST2019_00980] The role of End of Waste Criteria in the Framework of Circular Economy Strategy
by Zorpas A.

More than 1.8 billion tonnes of waste are produced each year in Europe. This equals to 3.5 t per person and are mainly produced from commercial activities (e.g. shops, hospitals, restaurants), industry (e.g. clothes manufacturers, pharmaceutical companies), agriculture (e.g. slurry), construction and demolition projects, mining and quarrying activities from energy production as well as from household activities.

[CEST2019_00981] Modeling and optimization of two-phase olive-oil washing wastewater phenolic compounds recovery and treatment by novel weak-base ion exchange resins
by Ochando-Pulido Javier M., Rubén González-H., Martínez-Férez A.

In the present work, the concentration and recovery of high-added value phenolic compounds from two-phase olive mill wastewater (OMW) and the simultaneous effluent treatment by a ‘green process’ based on resins adsorption/ion exchange was studied. Olive oil is produced by a technological procedure based on physical operations, without use of chemicals. This industry is concerned to make the whole process environmentally friendly, which includes the treatment of the wastewater produced in the mills. The proposed weak-based IE process was statistically optimized and modelled.

[CEST2019_00984] A small Overview of the current, Natural & Affected Environments by Microplastiscs
by Mafina K., Robertson I.

There is a growing concern and increasing evidence that microplastics in the World’s rivers and oceans are having an affect on marine environments; and ultimately into the food chain. Infrared Spectroscopy and Microscopy are well- established analytical techniques for defining, identifying and categorising of plastic materials. However, it is also good to remember that microplatics is a term that consists of diverse chemicals of all shapes, sizes, coulour etc.

by Lekkas D., Daskaloudis I., Vazaiou N., Iliopoulou A., Vourdougiannis L., Krassa E., Xypolias P.

In order to accommodate asylum seekers, who entered island Lesvos, Greece, refugee camp Kara Tepe was constructed. The solid waste of the camp are disposed at the landfill after they are gathered by the garbage trucks of Lesvos Municipality. In the current study preliminary values of the composition of solid waste analysis and estimated generation rate are presented. Main object is the proposal of an integrated and beneficial system of solid waste management in the refugee camp.
