The Heritage Areas are Protected Landscapes
Authors: Papakonstantinou George Faidon
Published: November 2022

Heritage Areas are areas of great natural, geological, aesthetic and cultural value. They have an important history and keep the traditions alive. Geological and natural processes from the early past to the present have evolved and contributed to the creation of Heritage Areas, so today we experience the heritage of exceptional cultural, natural and scenic resources.

The sustainable management of Heritage Areas focuses on preserving areas of cultural and natural significance for the future generations, while encouraging local communities to continue living and working in the region. These areas deserve special prevention and should be included in the National Systems of Protected Areas in accordance with international conventions and legal frameworks.

The framework for the management of Protected Areas in Greece has changed recently. Four new categories of protected areas now exist. Biodiversity Protection areas, National Parks, Wildlife Refugees, Protected Landscapes and Protected Natural Formations. This research supports the integration of Heritage Areas into the category of Protected Landscapes. By the implementation of the framework, the main advantage will then be to achieve real protection of an area of monuments, cultural importance, great natural value and beauty.

Published: November 2022

Microalgae-bacteria symbiotic systems have demonstrated greater benefits over the pure culture of microalgae. The existence of certain bacteria will increase the quality of sewage purification and also reduce the associated high capital cost for maintaining the pure culture of microalgae. In this study, the potential of four microalgal-bacterial symbiotic associations to accumulate lipid besides growth rate, biomass concentration, and to eliminate nutrients from secondary treated municipal wastewater was evaluated. The two microalgae strains, namely, Tetraselmis indica, Chlorella protothecoide in combination with Pseudomonus sp. and Bacillus pumilus were observed. Chlorella protothecoide-Pseudomonas sp. system achieved the highest lipid productivity of 37.93 ± 2.53 mg L-1d-1 with lipid content 25.67 ± 0.95 % after ten days of cultivation. The chlorophyll-a content of Chlorella protothecoide + Pseudomonas sp. has 32% higher than the pure Chlorella protothecoide culture in wastewater. On the 10th day, Chlorella protothecoide-Pseudomonas sp. system removed 83.59 %, 86.76%, and 81.35% of chemical oxygen demand (COD), total dissolved nitrogen (TDN), and total dissolved phosphorus (TDP), respectively. Chlorella protothecoide + Pseudomonas sp. could coexist as a consortium has the potential to be utilized in biofuel technology.

Authors: Psilovikos Thomas , Stergiadou Anastasia , Moutsopoulos Dimitrios
Published: November 2022

Wood is the only renewable material produced by photosynthesis. Wood has the ability to preserve the stored carbon in its molecular structure as long as remain within a structure. Small-scalelightweight timber dwellings are gaining recognition in Europe after the dominance of concrete and steel since the second World War . Nevertheless, public is still sceptical on their environmental impacts, structural behavior and durability. In Greece, small-scale timber dwellings became popular at rural and forested areas for their touristic attraction, aesthetic superiority and compatibility to the natural landscape. Information from literature and industrial studies showed that the use of structural timber has beneficial environmental impacts as well as economical impacts. Specifically, compared to other common building materials, timber has competitive structural characteristics, due to its low weight to strength ratio, low embodied energy and allows an easy and fast construction with minimum disruption to the environment. Moreover, lightweight timber buildings may have a high potential of waste re-use and recycling, when designed for future ease of deconstruction. The successful waste management contributes to circular economy. Local economy benefits directly from the all the relevant applications of wood.

Published: November 2022

This work presents a web-based policy tool for the development of effective particulate matter (PM) pollution strategies. The tool is based on an integrated modelling approach, from emissions to health effects, which allows testing measures to improve air quality, focused on PM2.5 levels, and quantitatively assess their impact on the health and well-being of the populations. The tool was developed in the framework of the LIFE Index-Air project and this work describes its particular application to Athens (Greece) simulating the effect of two air quality improvements measures on the PM2.5 levels. The application of the tool for the reference scenario indicates that Athens did not comply with the European air quality standards (25 μg.m-3) for the annual PM2.5 levels in 5% of the simulation domain. Two mitigation measures were simulated: i) fireplace improvement, and (ii) introduction of passenger electric vehicles. The results show that, in Athens, the electrification of the fleet is more effective, allowing to reduce up to 3 μg.m-3 on the annual average of PM2.5 concentrations. The tool allows for rapid exploration of potential air quality and health improvements resulting from different control measures, supporting stakeholders in decision-making.
Assessing the Utilization of Fuels Cells for the Valorization of Produced Excess Energy in Isolated Grids – The Green Transition of Agios Efstratios
Authors: Dimou Andreas , Vakalis Stergios
Published: November 2022

The island of Agios Efstratios is a unique case, since a pilot green energy transition program is taking place. Wind and solar photovoltaic technologies have seen tremendous growth during the past decade and various policy measures have been introduced in support of their growth. For the cases of islands that are not connected with the mainland grid the integration of renewable energy systems (RES) is a challenge, due to the variable performance for wind and solar. This study investigates the integration of electrolysis and fuel cells as a method to increase the penetration of RES in the isolated system of the island and to store hydrogen for other uses like green transportation. The software RETSCREEN was used for the analysis and the available excess energy from the renewables showed that it can support the operation of a 200 KW fuel cell system and the replacement of two small 90 KW diesel engines and would increase the overall RES penetration. At the same time, more than 20 tons of hydrogen could be stored annually for other uses.

Published: November 2022

Wildfires can trigger dramatic increases in surface runoff and erosion, because of the burned vegetation and the appearance of a condition of soil-water repellence. Fire-enhanced surface runoff generation and soil erosion constitute adverse effects of high concern for a long-term future period after a fire event occurrence. The current study investigates the increase on peak surface runoff and sediment loss as a result of a fire event that occurred in Pelion area in Greece on June 27th, 2007. The boundaries of the burned area were determined using satellite images, and the total burned area was found to be almost 60km2. The land cover of the area prior to fire event, mainly included forest, seminatural and agricultural areas as determined by the raster datasets produced by the Copernicus land cover program. The change of peak surface runoff discharge pre- and post- fire event was estimated using the Natural Resources Conservation Service – CN (NRCS-CN) method, while the sediment loss was also estimated. The fire event was found to significantly increased peak surface runoff, which may cause the occurrence of flood events in the downstream area.

Published: November 2022

Changes in land use and land coverage strongly interrelated with changes in runoff. The effects of land use and land cover change on peak surface runoff and sediment loss, was investigated in a mountainous catchment, namely Lakka catchment located in Thessalia region in Greece.Most of the Lakka catchment is covered by pastures, agricultural, forest and seminatural areas. Land cover of the study area for the years 1945, 1960, 1996, 2007 and 2018 was captured by the method of the photointerpretation, using the appropriate pairs of the aerial photographs and the stereoscopic glasses (SA030-4X), and by the method resulting from the use of the datasets produced by the Copernicus land cover program. The aim of the study is to investigate the evolution of peak runoff discharge during the period 1945-2018, against a background of land use and land cover change. The Natural Resources Conservation Service – CNmethod was utilized in order to estimate peak runoff discharge while the sediment transfer was also estimated. Agricultural land area was found to be significantly increased, against forest and seminatural areas during the study period, resulting to an increase of peak surface runoff, which may cause flood problems in the downstream areas.
Removal of amoxicillin from processing wastewater by ozonation and UV-aided ozonation: a kinetic and economic comparative study
Authors: de Castro Peixoto Andre Luis , Ribeiro Mariana , Ramos Bruno
Published: November 2022

A novel empirical and scaling up simulation study is presented for degradation and mineralization of real residue of amoxicillin (AMX) pharmaceutical formulation in wastewater. A set of UV-ozone-based experiments was used in the kinetics modeling of AMX, considering several chemical/photochemical mechanisms (direct ozonation, radical reactions, and photolysis). Finally, the modeling data was used for scaling up purposes, considering CAPEX and OPEX costs on the US Gulf Coast basis. In terms of experimental results, amoxicillin (AMX) pharmaceutical effluent was successfully degraded by ozone technology in high pH value. The semi-batch ozonation process was effective after 60-min treatment in all experimental conditions, producing degradation intermediates recalcitrant to the ozone oxidative process. From the bench-scale kinetics, scaling up simulations indicate that the smaller gain provided by adding a UV unit does not compensate for the increase in capital and operational costs of adding irradiation equipment, suggesting as the best cost-effective approach the application of direct ozonation.

Published: November 2022

The fatty acid (FA) distribution of bio-oil derived from Chlorella sorokiniana and the biodiesel basic properties were examined. C. sorokiniana was cultivated heterotrophically in two growth media: a) glycerol and inorganic salts (GLIN) and b) glycerol and anaerobic digestrate (GLAD). The cultivation took place in 42 L bioreactors. The bio-oil was extracted from the biomass collected. Extraction was performed using a mixture of n-hexane and isopropanol in a 3:2 ratio. The fatty acid (FA) distribution was determined in a gas chromatograph by converting the bio-oil in biodiesel. The fatty acid distribution covered chain lengths from C10 to C26. The great proportion of the FA were of medium chain FA C16-C18 constituting about 85% and 53% of the total fatty acids of the GLIN and GLAD treatments respectively. Also, the distribution of saturated, monounsaturated and polyunsaturated FA differed. The basic properties of the biodiesel such as the density, the kinematic viscosity, the acid value, the cetane number, the iodine value and the heating value were within the range of the respective values from biodiesel obtained from seed oils and differences in the properties of the two treatments were explained in terms of differences in FA distribution.

Published: November 2022

The presence of antibiotics in the environment has received a lot of attention in recent years due to their ability to promote and spread antimicrobial resistance. In this work, the biodegradation of the antibiotics ciprofloxacin (CIP) and sulfamethoxazole (SMX), as well as the concurrently generation of their biotransformation products (BTPs) were assessed in an anaerobic packed bed biofilm reactor (APBBR) treating sanitary sewage. Initially, anaerobic batch assays at high concentrations of the antibiotics (5 mg L-1) were performed to identify the metabolites generated during the CIP and SMX biodegradation in methanogenic condition. From the mass transitions (m/z) of the identified BTPs, they were analyzed along the spatial profile of the APBBR fed with sewage (300 ngCIP L-1 and 400 ngSMX L-1 approximately). Three BTPs were identified: one related to the biodegradation of CIP (m/z 316) and two related to the biodegradation of SMX (m/z 256 and m/z 270). The molecular structures of the BTPs revealed that the biotransformation occurs mainly in the isoxazole ring of SMX and there was a dehydroxylation in the CIP molecule. Nonetheless, the sulfonamide and fluoroquinolone molecular structures remained intact in the anaerobic effluent stream, thus presenting residual antimicrobial activity in the environment.

Authors: Zorpas Antonis , Demetriou Maria
Published: November 2022

This study aims to analyze the changes in air pollution levels during lockdown measures in Cyprus. Lockdown measures came into force from March 13th 2020, few days after the first COVID-19 case was registered. The study analyses the data from different air quality monitoring stations in Cyprus in order to estimate air pollutant concentration variations during lockdown period. The data collected was compared to the previous year’s monthly values of emissions. Results show that during the lockdown period, there was a significant reduction on NOx, NO and NO2 (65,07%, 75,20% and 59,67% respectively) at the traffic air quality monitoring stations. A lower reduction was observed for CO (28.50%) and C6H6 (58,34%). SO2 concentrations did not show significant reductions while ozone levels (O3) increased. The results clearly show the traffic-related air pollution and necessitate further design strategy plan about the allocation of the traffic volume and the promotion of public transportation and the use of alternative fuels.

Published: November 2022

Information about the biotransformation of organic micropollutants (OMPs) in biological systems is currently scarce, particularly in anoxic environments. A lab-scale reactor was set up to elucidate which is the biological mechanism driving OMPs biotransformation in heterotrophic denitrifying conditions. The influence of microbial composition on the OMPs removal was analysed. Increasing levels of nitrate loading rates were applied during the study in order to analyse cometabolism. In terms of OMPs, high removal efficiency was achieved for compounds such FLX and SMX, whereas moderate removal was achieved for some antibiotics (ERY, ROX, TMP), the anti-depressant drug CTL or the natural hormones. Other OMPs, like DCF or CBZ were recalcitrant. Removal due to cometabolism was detected for BPA, ERY, ROX and CTL.

Published: November 2022

The periodic removal of sediments is necessary to ensure the functionality of ports, to facilitate navigation, for construction, expansion and environmental cleanup processes. The management and fate of the resultant tons of dredged material is a costly issue that must be addressed. Many technologies for the disposal of dredged sediments take no consideration of sediment’ reclamation. However, in line with the principles of the circular economy sediment should be treated as a new resource for sustainable reuse rather than as a waste.
The aim and the scope of this paper is to examine the possibilities of sediment’ management in the context of the circular economy by presenting sustainable, economically and environmentally friendly "green" management options of dredged sediments. Case studies of alternative and beneficial uses of sediments include the development and restoration of coastlines and landscapes, the construction of water barriers and flood works, sediment use in agriculture, in the production of bricks and ceramics, as well as for road construction.
Real-scale Analysis of Riparian Vegetation Deformations and Flow Resistance of Vegetated Streams
Authors: Lama Giuseppe Francesco Cesare
Published: November 2022

The objective of this study is the comparative analysis of the main hydrodynamic traits of vegetated streams and riparian vegetation 3D bending through the processing of real-scale measurements retrieved during field hydraulic experiments in a vegetated water body colonized by young flexible riparian weeds. The structural measurements of riparian vegetation bending were carried out by employing a built-in system of micro load cell sensors, implemented during three years of Research program and calibrated in specific Laboratory Flume tests, and then installed directly on the weed flexible stems in the field in real vegetated water streams. The measurements were carried out continuously, aiming at correlating the riparian weed deformation to the complete 3D water flow field. The promising outcomes of this study represent a useful tool for the prediction of the effects of riparian vegetation in vegetated channels colonized by such a widespread riparian species like reed beds.

Published: November 2022

In this paper, an advanced numerical model for the simulation of wave propagation and transformation in coastal areas and inside ports is presented. This model is a fully dispersive and highly nonlinear 2DH Boussinesq-type model, extended to cover real-life applications, capable of simulating the transformation of complex multi-directional irregular wave fields in coastal and harbour areas with varying bathymetries. This version of the model is coupled with wave overtopping empirical formulae as described in the EurOtop (2018) manual. The numerical model when compared with experimental data showed that a more than satisfactory agreement was achieved in most cases. A real case study, in the coastal zone of Rethymno in the Island of Crete, Greece, including the including the current port infrastructure, is also presented.

Published: November 2022

The incorporation of nanomaterials in membrane’s matrix aims mainly to improve the properties of the membranes such as hydrophilicity, mechanical strength, thermal stability, water flux. Multi-walled carbon nanotubes (MWCNT) and functionalized graphene oxide (fGO) have recently attracted attention, as they have proved to have potential in various applications. In this study, self-assembled MWCNT-fGO nanocomposite was synthesized and used as a filler in environmentally-friendly polylactic acid (PLA) membranes. The membranes were fabricated following the phase inversion method with different concentrations of MWCNT-fGO (2, 4, 6 and 8 wt.%). In addition, the membranes were tested for the removal of heavy metal ions from wastewater. The results showed that a considerable removal can be achieved using the composite membranes. For instance, the highest Cu2+, Ni2+ and Zn2+ removal (e.g., 89%, 35%, and 39%, respectively) was observed in the 8 wt.% MWCNT-fGO PLA membrane. This was achieved at water flux of 850 L·m-2·h-1 (LMH). On the other hand, the pristine PLA membrane water flux was around 450 LMH and was capable of achieving 82, 25, and 30% rejections for Cu2+, Ni2+ and Zn2+, respectively. These results showed the potential of the MWCNT-fGO PLA membranes application in treating heavy-metal containing wastewater.
On the Fenton oxidation of polystyrene microplastics

Published: November 2022

This work aims at evaluating the fate of polystyrene (PS) microplastics along Fenton oxidation. Experiments were carried out under relatively severe operating conditions (80 ºC) given the high persistence of these solids to oxidation. Slight mass losses (up to 10%) were found after the Fenton treatment of microplastics in the micro range (100–250 m). Nevertheless, the particles clearly suffered important changes in their surface due to the introduction of oxygen groups, which made them more acidic and hydrophilic. These surface alterations completely changed the sorption properties of microplastics. For instance, their adsorption capacity for diclofenac was sharply decreased from 102 to 28 g g-1. Apart from surface modifications, microplastics clearly decreased their size after Fenton oxidation, which was more evident in the 50–100 m range. To further evaluate the oxidation yield of PS microplastics upon Fenton oxidation, particles in the sub-micro range (140 nm) were treated. Notably, up to 75% TOC mineralization was achieved, which proved that microplastics can be completely oxidized to CO2 upon Fenton oxidation. Finally, the biodegradability of the dissolved compounds leached from oxidized microplastics was evaluated. Remarkably, bacterial growth efficiency was higher in the solution coming from the oxidized PS microplastics than that of the fresh one.
Optimized use of biogenic waste streams through the combined production of bio-based products and bio-hydrogen
Authors: Küppers M. , Brunstermann R. , Widmann R.
Published: November 2022

Since 2015, there has been a legal obligation in Germany for the districts and cities to collect biowastes separately, which are then treated in a composting plant or fermentation plant. However, in both aerobic and anaerobic biowaste treatment, a large part of the carbon contained in the waste is released in the form of carbon dioxide (CO2) without using the raw material potential it contains. Against the background of efforts to save climate-relevant gases and the scarcity of natural resources, the aim of biological waste treatment should be to make better use of the potential of bio-waste through innovations in the known treatment processes. These innovative processes should make better use of the carbon contained in the biomass and obtain higher-quality and economically profitable bio-based products from it, to substitute primary raw materials.
In a first step, the anaerobic process of dark fermentation initially produced short-chain carboxylic acids from organic waste streams. This process also produces a hydrogen-containing biogas that can be used for energy. In a secondary fermentation, the carboxylic acids are then to be lengthened and separated using a non-polar extractant. The extended carboxylic acids then serve as platform chemicals for the manufacture of various bio-based products.

The present study uses data from the TROPOspheric Monitoring Instrument (TROPOMI) on board Copernicus Sentinel-5 Precursor satellite to investigate the impact of the forest fires plumes on atmospheric aerosols and gases. For this purpose, the Aerosol Index, nitrogen dioxide (NO2) and carbon monoxide (CO) Level-2 data have been analyzed. The results show that the fire in Kineta, Attica (in 2018) and the fire in Corinthia (in 2021), enhanced the total CO concentration levels by up to 5.5 times (from 1.5x1018 to 10x1018 molecules/cm2) and up to 4 times from 1.5x1018 to 6x1018 molecules/cm2), respectively. Similarly, the tropospheric NO2 concentration levels have increased by up to 15 times (from 1x1015 to 16x1015 molecules/cm2) and up to 40 times (from 1x1015 to 4x1016 molecules/cm2), respectively. Fires have also increased the atmospheric load of absorbing aerosol as reflected by the increase of the dimensionless AI by up to 6 times (from 0 to 6 and from -2 to 4 respectively).

Published: November 2022

The cultivation and production of biomass of prickly pear is of particular interest due to the fact that it can be grown in arid areas, producing higher amounts of biomass with lower inputs (water, fertilizers etc.) compared to other crops. The present study examines whether enzyme hydrolysis is capable to increase the amount of reducing sugars available to S. cerevisiae E1A strain to be used during alcoholic fermentation. Enzymatic hydrolysis was performed using the commercial enzymes Termamyl and Celluclast applied at various concentrations of dried cladodes and of dried fruit and added juice from discarded fresh prickly pears in order to enrich the quantity of sugars into the solution. The substrate used in the bioreactor experiment consisted of 100 g/L of dried cladodes with 40 g/L of dried fruit, which after the addition of the juice resulted in the synthesis of a liquid growth medium containing 48 g/L of sugars. The microorganism finally managed to produce a significant amount of endopolysaccharides inside the yeast biomass (22.12% w/w) while biomass (DCW) production was of 4.35 g/L. Ethanol at 21.54 g/L with a yield of ethanol produced per unit of sugar consumed YEtOH/S was equal to 0.49 g EtOH / g of substrate.

Published: November 2022

The Mediterranean region is considered as one of the world’s most water-stressed areas where some countries have less than 1000 m3 capita-1 year-1. This situation, exacerbated by climate change, is due to, but not restricted to, the relatively uneven distribution of precipitation, high temperatures and increasing water demand, especially for agricultural purposes. Under this context, the use of Non-Conventional Water (NCW), as drainage and treated wastewater, is one of the most sustainable alternatives to cope with water shortage.
The MENAWARA project is designed to enhance access to water through the treatment of wastewater to be reused as complementary irrigation and to strengthen the operational capacity of stakeholders of the quadruple helix, including local farmers, in 8 intervention areas of Palestine, Jordan, Tunisia, Spain and Italy. The actions will reduce the stress on freshwater sources from the agriculture sector and will improve the quality of treated wastewater in agriculture. Clean and environmentally friendly technological, managerial, and operational innovation will be applied and results shared among relevant stakeholders. MENAWARA will play an important role in reducing water insecurity by designing the most suitable post-treatment or Managed Aquifer Recharge (MAR) system for each intervention area and by promoting sustainable development in rural areas.

The presence of high concentrations of VOCs in the atmosphere can lead to negative consequences for humans and the environment. The treatment of these compounds is thus necessary before their release into the atmosphere. In the study, an advanced moving bed biofilm reactor (MBBR) coupled with an algae photobioreactor (APBR) is presented with the aim of investigating its application for the sustainable biodegradation of toluene (C7H8). The results highlight that the MBBR alone shows a high removal efficiency (RE), ranging from 98.37 ±0.79% to 99.84 ±0.14%. Whiile, setting the Algal PhotoBioreactor (APBR) as second treatment, the biodegradation of toluene increases up to 99.91%. The research depicts the potential of the investigated system to biodegrade volatile organic compounds (VOCs), leading to a healthy environment.

Published: November 2022

In order to reduce costs related to water supply service, modernization measures should be carried out to water losses. The paper presents an analysis and assessment of water losses carried out based on data provided by a water utility company. The basic indicators of water loss according to the International Water Association were then determined, such as: the leakage percentage (LP), the real leakage balance (RLB), the unavoidable annual real losses (UARL), and the infrastructure leakage index (ILI). On the basis of the categories given by IWA, we can see that the analysed water supply network is classified as a network of very good technical performance. The obtained water loss indicators in the examined water supply system (WSS) are comparable to the indicators in other collective water supply networks in Poland.

Published: November 2022

The crab species africanus is a very notable detritivore, feeding on dead organic materials. It makes use of energy from the food and transfers it into the food chain trophic level, contributing to the gross ecosystem efficiency. However, their threat to human consumption and activities is gradually high in the sub-Sharan regions. There is a need to exploit alternative methods for traditional domestic cultivation to ensure food security. This study reported the length-weight relationship, condition factor, sex ratio, fecundity, and GSI (gonadosomatic index) of Sudanonautes africanus to prospect possible domestication. The result of the biomass of Sudanonautes africanus indicated a mean range of 52-180 g. A positive relationship existed between the weight and length relationship of the male and female crab with positive (+) allometry. There was no significant difference between both sexes. However, the fecundity estimates showed a ripe carapace full of bright red gonad materials (stage V) specifically in the female with eggs range of 2.56 to 8.95 g and GSI range of 11.28-41.44%; with the minimum (15) and maximum (27) fecundity at July and June 2016 respectively. It was concluded that the species could be domesticated via aquaculture because of its potentials to adapt to various feed substrate and water parameters.
Mechanism of tolerance and adaptive strategies developed by Moringa oleifera (L) during its growth under a salt constraint in hydroponics

Published: November 2022

Moringa oleifera (L) is a promising species to be used in reforestations of dry areas. A question that remains to be investigated is its resistance to salinity conditions. This work’s major goal was to investigate the response of this species in increasing salinity conditions, in order to increase our understanding on the mechanisms of tolerance and/or sensitivity and of the morpho-physiological and biochemical responses of Moringa plants under a salt constraint. Moringa seedlings were subjected to increasing concentrations of NaCl, 0 (control), 50, 100 and 150 mM NaCl. The results suggest that the variations in the responses of the parameters analyzed depend on the concentration and the duration of application of the salt. Vertical growth, relative average growth rate (RGRh), and relative water content showed a great variability of responses, depending on the concentration and the duration of application of NaCl. Leaf area (SF) was affected by salinity whereas leaf succulence index (ISF) and photosynthetic pigments (chlorophylls (a), (b), were significantly improved by such stress. The results suggest a strong resistance of the species to high doses of NaCl and in particular those greater than 50 Mm. Salinity conditions cause the accumulation of organic solutes (proline and soluble sugars), as a physiological adaptation to prolonged salinity.
