Integrating Urban Heat Island Mitigation into Green Building Rating Systems
Authors: Almashhour Raghad , Kolo Jerry , Beheiry Salwa
Published: August 2023

Amidst the climate crisis, cities remain the foremost cause and victims of the Urban Heat Island (UHI) effect. UHI is the higher temperature observed in a city compared to nearby rural environments. The built environment, in particular buildings, are known to be highly responsible for heating up or increasing the temperature of spaces in which they are built. Due to environmental and public interest concerns, how buildings are approved and constructed should be of concern in the fight against the UHI effect and climate change. Currently, municipalities use the Green Building Rating Systems (GBRS) to analyze the environmental performance of buildings. Reviews of the GBRS show that they primarily focus on energy consumption and carbon emissions in buildings. There is no evidence that GBRS assess how municipalities monitor or regulate the heat emitted by buildings. This research is designed to empirically ascertain from architecture, engineering, and construction (AEC) professionals how municipalities can directly, through their regulatory processes or indirectly though the GBRS, gauge the heat emitted by buildings, and prescribe pragmatic mitigation measures. The study was conducted through a questionnaire survey that will be administered online via snowball sampling. The outcomes of this research should provide practical insights into how UHI mitigation can be integrated into GBRS used by governments. Such integration will add value to the broader efforts of governments to combat climate change.
Circular Economy: Assessment of Circularity in Olive Oil Mills
Authors: Kounani Aristea , Pavloudi Alexandra , Aggelopoulos Stamatis , Kontrogeorgos Achilleas
Published: August 2023

A central issue for academics and politicians regarding the circular economy in the last few years has been the evaluation and monitoring of the circularity level, so that conclusions can be drawn about how the implemented policies have been transitioning toward sustainability. Even though the research community has been working extensively on this subject, there has not been a consensus on what indicators to use to measure circularity in the agri-food industry so far.

The aim of this paper is to highlight the circular economy (CE) indicators used in the agri-food sector, based on scientific literature and practice, so as to identify those that could assess circularity in olive oil mills. Furthermore, the project aims to develop a tool that will be able to assess the success of CE strategies and remove some of the ambiguity surrounding CE in practice. Due to the uncontrolled disposal of waste from olive mills, the Mediterranean countries that produce the majority of olive oil have to cope with major environmental issues, so the transition to a CE in olive oil industry is essential.

Published: August 2023

Microcystins (MCs) are potent cyclic-peptide toxins produced by cyanobacteria during freshwater bloom episodes. They can severely impact drinking water supplies and recreational waters. More than 300 MCs are known today, which are toxic, mainly by inhibiting protein phosphatases. MC-RR is an important congener, as shown in several bloom episodes. There are still serious gaps of knowledge regarding the reaction pathways and transformation products of MCs with reactive species which have a role in advanced oxidation processes (AOPs) or in degradation processes in natural waters. In this study, we applied the principles of radiation chemistry of water to investigate the transformations of the less-studied MC-RR by a range of oxidizing (hydroxyl radical, superoxide ion, hydroperoxyl radical) and reducing (hydrogen atom, hydrated electron) species. We manipulated a steady-state radiation-chemical system using scavengers to investigate and quantify the effects of single species. We used high-resolution mass spectrometry combined with computational and visualization platforms to annotate MS features of transformation products and to compare the single-species reaction pathways. Our results contribute to risk assessment concerning the fate of MCs in water treatment processes and in the environment.

Authors: Šilha David , Syrová Petra , Syrová Lenka , Janečková Jana
Published: August 2023

Smoothie drinks are currently very popular drinks sold, especially in fast food establishments. However, smoothies are a significant source of microorganisms with a high level of antibiotic resistance. The study aimed to evaluate the microbiological quality of smoothies purchased in Eastern Bohemia. A higher prevalence of mesophilic aerobic bacteria (5.4–7.2 log CFU/mL), yeast (4.4–5.9 log CFU/mL), and coliform bacteria (3.1–6.0 log CFU/mL) was observed in vegetable smoothies, in which even the occurrence of enterococci (1.6-3.3 log CFU/mL) was observed. However, the occurrence of S. aureus, Salmonella spp., and Listeria spp. was not observed in any sample. Nevertheless, a significant occurrence of resistant microbial strains was observed in all samples. The highest resistance level was found in isolates from smoothie drinks with a dominant vegetable content (green-smoothie drinks). Considerable resistance was observed in Gram-negative rods, especially to amoxicillin (82.2%) and amoxicillin with clavulanic acid (55.6%). Among enterococci, only one vancomycin-resistant strain was detected. The vast majority of isolated strains were able to form biofilms at a significant level, which increases the clinical importance of these microorganisms and their resistance. The highest biofilm production was found in Pseudomonas aeruginosa, Kocuria kristinae, and Klebsiella pneumoniae. Overall, significant biofilm production was also noted among isolates of Candida spp.
Ethical considerations of participatory modelling in the context of sustainable development
Authors: Amorocho-Daza Henry , van der Zaag Pieter , Susnik Janez
Published: August 2023

Sustainable development deals with grand challenges related to human well-being and environmental sustainability. Assessing sustainability initiatives goes beyond technical solutions and requires the engagement and deliberation of multiple stakeholders. Participatory modelling is a promising approach to explore sustainability alternatives by using technical tools (e.g. simulation) while actively involving stakeholders. The discussion around sustainability alternatives has ethical implications as it deals with matters that affect people and the environment. However, despite ethical aspects are implicit in participatory modelling processes, they are often overlooked. This study aims to make visible the ethical dimension of participatory simulation models in the context of sustainability. Here we propose to have sustainable development and human rights as ethical standpoints for participatory modelling efforts in complex social-ecological settings. A practical-oriented ethical evaluation is proposed in the form of questions structured across a relevant participatory modelling framework. An ethical lens is essential to guide social-ecological systems modelling throughout to identify pathways that align with principles aiming to protect human dignity, promote justice, and prevent environmental harm. The proposed ethical framework aims to promote the design of socially accepted and ethically transparent models that support decision-making processes aligned with the Sustainable Development Goals (SDGs) transitions.

Published: August 2023

Environmental noise is a global problem with multiscale consequences, affecting human well-being, environmental health and business efficiency. Several tourist accommodations aiming towards a more competitive and profitable business, produce the by-product of noise thus resulting in a higher noise footprint. The aim of this research is to propose an approach towards the assessment and calculation of the noise footprint of tourist accommodations. Three tourist accommodations located in Lesbos Island (North Aegean Greece) were studied. The transportational, functional, natural and recreational sound sources were assessed. Furthermore, the degree of background noise was included. Noise measurements were conducted using a calibrated sound level meter. The equivalent continuous sound level (Leq) noise indicator levels for each type of source were obtained and analyzed. In order to assess the overall noise footprint a composite indicator based on the signal to noise ratio was shaped. Furthermore, noise maps were created in order to visualize the noise footprint extent of the hotels studied. The main findings of this research highlighted the seasonality of the resulting noise footprint. The promotion of natural and recreational sound sources contributes towards the new concept of net-zero noise and supports quiet and sustainable tourist accommodations.
Exploring the effects of static magnetic fields for the enhanced valorization of sewage sludge by anaerobic digestion
Authors: Di Costanzo Nicola , Cesaro Alessandra , Di Capua Francesco , Mascolo Maria Cristina , Esposito Giovanni
Published: August 2023

Anaerobic digestion (AD) is an interesting and sustainable option to handle sewage sludge (SS), as it generates a methane-rich biogas and a digestate with potential fertilizing properties. Several strategies have been proposed to enhance AD performances and the valorization of SS. Among these, the application of a static magnetic field (SMF) has been poorly evaluated and recently gained attention. This work investigated the effect of low-intensity SMF (20-50 mT) on methane production from AD of SS, comparing it to the effect deriving from the application of a high-intensity SMF (1.5 T). Magnetic pretreatment at 20 mT was particularly effective, as it increased biomethane production up to 12.9% compared to the control test. On the contrary, 1.5 T was detrimental in terms of cumulative methane production, as it resulted in a 20.9% decrease. These outcomes suggest that SMF intensity is inversely related to biomethane generation and that further investigations are worthy to understand the mechanisms underlying AD enhancement by SMF application.

Published: August 2023

Freshwater scarcity remains one of the most crucial issues facing our world. Although the traditional membrane distillation (MD) technique can efficiently produce clean water irrespective of climate conditions, the process wastes a lot of energy. Thanks to the development of photo-thermal materials, the solar-powered membrane distillation (SPMD) process has received intensive attention in the last decade. SPMD is a highly promising substitute for traditional MD, which is based on fossil fuels, as it can stop the harmful emissions impact on the environment. Combining solar energy with MD has the potential to lower the expenses associated with water purification and ensure the generation of clean water remotely. Reviewing the most current advancements of the SPMD system is essential at this point, in addition to highlighting the challenges and prospective of this technology. Based on that, the background, recent progress, and principles of SPMD, their configurations and mechanisms, fabrication methods, and various applications, along with their advantages and current limitations, are reviewed.

Published: August 2023

Freshwater cyanobacteria are prominent sources of structurally diverse natural compounds. Bioactive cyanometabolites are particularly relevant to water quality and public health protection. Non-targeted analysis (NTA) by liquid chromatography - high resolution mass spectrometry (LC-HRMS) is applied to expand the range of detected and identified metabolites. However, data analysis is challenging and subjected to limitations arising from the availability of experimental or library-based mass spectra. We present an HRMS data analysis workflow using state-of-the-art computational tools that we have applied to analyze samples from cyanobacteria blooms in Greek lakes. Pre-processing of data was carried out in MZmine3 (feature detection, deconvolution, alignment, deisotoping, gap filling). Processed data were exported in GNPS for feature-based molecular networking - FBMN and annotations based on public GNPS libraries. In parallel, feature lists were processed in SIRIUS and its associated tools, for de novo molecular formula annotation, database search, prediction of compound classes using molecular fingerprints, and ranking of candidates using fragmentation trees. Results were visualized and further explored in Cytoscape, to enable annotation propagation. Such workflows substantially expand the chemical space of annotated cyanometabolites at structural and compound-class levels, and the discovery of new compounds which are not included in libraries.
Rule-based Quantification and Mapping of Ecosystem Services Across Three Spatial Scales by Example of Germany
Authors: Schröder Winfried , Schlutow Angela , Nickel Stefan , Jenssen Martin
Published: August 2023

The state of ecosystems influences their services for humans. Therefore, the European Union aims to assess and map ecosystem conditions and ecosystem services at the level of the Union and the Member States, in order to implement maintenance or protection measures, if necessary. This paper aims at creating a methodology allowing to quantify and map the potential supply of selected forest ecosystem services over time, considering the influence of climate change and atmospheric nitrogen deposition which is, in contrast to previous approaches, reproducible. Therefore, the methodology was operationalised in a rule-based manner enabling to quantify and map ecosystem services at the local, regional and national level using Germany as an example. To this end, in a first step 125 near natural forest ecosystem types covering Germany were grouped into 78 classes according to the degree of similarity of their ecological characteristics that influence the provision of ecosystem services. Thereby, ecoclimatic, soil, hydrological, nutrient balance characteristics and 12 potential ecosystem service capacities were taken into account. Three potential ecosystem services (habitat, carbon storage, primary production) were quantified for selected representatives of the ecosystem type classes according to complex, but fully transparent rules, and mapped at the local, regional and national level.
Nitrogen & Phosphorous Removal via Anaerobic / Anoxic-Aerobic Processes and Struvite Formation in Mall Wastewater: Performance of Retrofitted Full-Scale Plants
Authors: Rollon Analiza , Maceda Ma Cleofas , Sinoy Ma Concepcion
Published: August 2023

With the new standards on nitrogen (N) and phosphorous (P) in wastewater discharges from industrial, commercial and municipal wastewater, there is a need for better wastewater treatment systems. Moreover, with the presence of such N and P in wastewater, struvite formation leading to clogging of pipes has also been a problem in wastewater treatment systems. This study aimed to improve N and P removal from mall wastewater through retrofitting with the inclusion of anaerobic/anoxic process prior to the existing aerobic process and recirculation of part of the effluent from aerobic process to anoxic tank in order to achieve ammonification of organic nitrogen, nitrification and denitrification in the whole system. The recovery of struvite, which is magnesium ammonium phosphate (MgNH4PO4), is also expected to be another pathway via which N and P can be removed from the wastewater. Seven mall wastewater treatment plants were monitored. Both the previous and new system include chlorination as a final treatment. The treatment performance with respect to the removal of N and P of the new retrofitted system is better than the system where the biological treatment process was mainly aerobic. Better levels of organic matter, oil and grease, total suspended solids (TSS), surfactant and fecal coliform were also achieved. The levels of N and P in the effluents of the anaerobic/anoxic process has become so low that precipitation of struvite via magnesium dosing is not feasible. Struvite formation already occurs at the mixing tank after anaerobic/anoxic tank. The new wastewater treatment system, with reduced aeration requirements, where N and P were removed by nature based bacteria and without the use of large dose of chemicals becomes a cost-effective solution for a cleaner environment.
Air-19: Reliable monitoring of air quality and microorganisms in postpandemic municipality building
Authors: Katsiri Eleftheria
Published: August 2023

Nowadays, the link between air pollution and covid-19 is proven beyond doubt in the literature with key pollutants being particulate matter and CO2. Our team has been involved in the development of reliable air quality sensing devices using low-cost sensors measuring particulate matter, differential pressure, humidity, and temperature. We have developed a new measuring device, that detects with high reliability CO, CO2, humidity, and temperature but also viruses in ambient air. The new architecture consumes less power and supports the integration of industrial CO2 sensors operating at 12 to 24 volts and using the industrial 4-20mA protocol. Furthermore, five novel near-real-time indices were developed to model risks that endanger public health indoors: a) risk of infection, b) ventilation efficiency, c) aggregated exposure d) AQI and e) congestion. Real-time data streams from six devices (three PM ones and three C2O2O ones, in pairs) that were deployed at a municipality building in the center of Athens, Greece, during a 5-month-long pilot application were used for the indices calculation also generating real-time warnings. Results show that congestion exceeds the limits frequently in the cashier area on the third floor during visitor hours while outdoor pollutants penetrate indoors from a busy road.

Published: August 2023

Iodine is an essential trace element in the human diet being involved in the synthesis of thyroid hormones. Iodine deficiency affects ca. 2.2 billion people worldwide, therefore it is an important challenge to find a plant-based source of iodine, which would provide the recommended dietary allowance.
In this work iodine biofortification of cabbage was studied cultivating plants in hydroponic system containing iodine in concentration of 0.01-1.0 mg/L as potassium iodide or potassium iodate. During the experiment plant physiological properties, biomass production, concentration changes of iodine- as well selected essential elements were investigated. In addition, chemical form of the accumulated iodine in root samples was also determined.
Results showed that iodine addition had no effect on the photosynthetic efficiency and chlorophyll content. Biomass production was stimulated by the iodide treatment in all dosages, while applying iodate this phenomenon was observed only in low concentrations, above 0.5 mg /L the yield was reduced. Increasing iodine concentrations in the nutrient solutions resulted in higher iodine content in all plant parts, the presence of iodide caused 2-7 times higher accumulation compared with the iodate treatment and it was established that in cabbage roots reductive reactions are dominant, iodate was converted to iodide.

Comparative life cycle assessment of lithium-ion batteries
Authors: Vlachokostas CHRISTOS , Tournaviti MARIA , Savva CHRISTODOULOS
Published: August 2023

The transportation sector is the second largest source of carbon emissions worldwide. In the process of achieving zero emissions, the electrification of the sector and the replacement of internal combustion engine vehicles (ICEVs) with electric vehicles (EVs) is being promoted. Batteries as the main component of EVs contribute significantly to their environmental impact along their life cycle. The high energy demand for battery production leads to higher carbon emissions to produce EVs than ICEVs. Additionally, during the charging of the batteries, the carbon emissions are directly linked to the carbon intensity of the electricity mix used. Currently, lithium-ion batteries (LIBs) are widely used as energy sources for EVs. This paper presents a comparative life cycle assessment (LCA) of three types of LIBs: lithium-ion phosphate, lithium manganese oxide, and lithium nickel manganese cobalt oxide. The environmental impact of the entire life cycle of the batteries, from the extraction of raw materials to end-of-life (EoL) management, was assessed. The results were then compared for the three battery types. The influence of the electricity mix used to charge the batteries was also assessed, by applying a different scenario of electricity mix for power generation than the base case.

Published: August 2023

Despite the concept of citizen science being around for a few decades, it is still considered a non-traditional data source, especially in policy circles. Further efforts are needed to build its acceptability by decision makers at various levels of governance. Determined to make this happen, the COMPAIR project sets out to deploy advanced quality assurance measures in the form of distant calibration to make citizen science data policy-ready. Additionally, the project will engage the entire urban value chain in pollution monitoring and analysis, with a special focus on people from lower socioeconomic backgrounds. Local stakeholders will get access to comprehensive, accurate and easily accessible information on air pollution via three purpose-built digital tools: the Policy Monitoring Dashboard, the Dynamic Exposure Visualisation App, and the CO2 Calculator and Simulator. By leveraging data-driven insights from these tools, members of the quadruple helix community will be able to co-create appropriate measures and strategies to set smart cities on a more carbon-neutral footing and reduce air pollution to levels that are considered safe for all.

Authors: Bertsiou Maria Margarita , Baltas Evangelos
Published: August 2023

Water scarcity problems and the need for reduced consumption of fossil fuels lead to the transition to renewable energy sources (RES). The proper management of RES is the key issue, especially in small not interconnected islands. In this research work a Hybrid Renewable Energy System (HRES) on a small island in the Aegean Sea is evaluated for ten years of hydrometeorological data. The objective is the production and storage of the required energy for the electricity needs of the area, as well as, for the desalination of seawater for domestic and irrigation water fulfillment. Results concerning the reliability of the system, the fulfillment of water and energy demands and the loss of load expectation are presented. The simulations will give valuable information about the produced and stored energy, its controlled distribution for the water and energy demands of the island and HRES’s potential in these demands of the local society over one decade.

Bioremediation of environmental heavy metal contamination presents a valuable tool for an effective and low-cost method of containing and minimizing the harm of heavy metal contaminations. However, many common bacteria used in this application such as Acidothiobacillus ferroxidans do not have intrinsic rsistances to environmental heacvy metal. In this paper an attempt was made at using the traJ gene to trasnfer a plasmid containing antibiotic resistance and a mutated from of the rusticyanin protein as a test for future insertions of heavy metal resistance genes. While this was unsucessful important insights into the mechanistic requirements of conjugative gene trasnfer in A. Ferroxidans were identified.
Management of Table Olive Wastewater (TOWW) in Turkey
Authors: Dolgen Deniz , Alpaslan Mehmet
Published: August 2023

Table olive is very important agricultural product for Turkey. It has a great market share in the country and also have high export potential. Management of table olive wastewater (TOWW) is an emerging and important issue, since large volumes of TOWW are discharged with high concentrations of organic matter, phenolic compounds, suspended solids, alkalinity, and conductivity. Current practices in many countries are the storing the wastewater in evaporation ponds or discharging to municipal wastewater treatment plants, if the ratios are relatively acceptable. Application of evaporation ponds in Turkey is not suitable, because of high population densities in olive production areas and high prices of land. Plus, generally the locations of the production plants are far away from the sewerage systems. Those facts impose the planners and engineers to develop technological treatment based technological in-site solutions for the management of TOWW. In order to perform proper treatment methods, the quantity and quality of wastewater should be known first. However, it is not an easy job, because neither producer provides reliable information nor there is enough information in the literature. In the paper, a questionnaire survey carried out app.30 firms located in the Akhisar Olive and Olive Derivatives Specialized Organized Industrial Zone (AZIOSB) The questionnaire helped to project the data on wastewater generation as well as the processing techniques of table olives. Plus, the sampling studies for quantity and quality of the wastewater are conducted at the main outlet of the AZIOSB, and accordingly treatment alternatives for TOWW are discussed.

The detection of pharmaceuticals and personal care products (PPCPs) in environmental matrices raised concerns over their short- and long-term effects on the ecosystem. Wastewater is the primary carrier of PPCPs to the environment in highly urbanized regions. In the Philippines, Manila Bay serves as a drainage basin for most of the streams of surrounding urban cities, hence, a cumulative drainage basin for effluents transported downstream. Water samples from the surface and the bottom layers of Pasig River mouth and Manila Bay were collected for PPCP analysis. Pharmaceuticals and pharmaceutical-related compounds, such as carbamazepine, clarithromycin, diclofenac, anhydroerythromycin, acetylsulfamethoxazole, trimethoprim were detected, as well as possible untreated wastewater tracers like caffeine and acetaminophen. Total concentrations were higher in Pasig River compared to Manila Bay due to the dilution of river water entering a bigger water body. Vertical variations in PPCP concentrations in Pasig River are not significant. In contrast, the top layer of Manila Bay is more contaminated compared to the bottom potentially due to stratification. Differences in PPCP profiles show how variable contaminants depend on external factors. The presence of PPCPs in natural systems highlights the need for more stringent and targeted wastewater management.
Changes in geomorphic units alter nitrogen fixation in a large lowland tropical river

The present investigation was carried out over 50 km reach, the Padma River of Bangladesh, downstream of the confluence of the Ganges and Brahmaputra rivers. The study area is highly dynamic, with diverse geomorphic units, high rates of bank erosion, and sediment abstraction. Sentinel-2 imagery (2019-2020) was processed using NDVI values to classify in-channel geomorphic units (GUs) of the study area. The identified GUs categorised as primary and secondary channels (C&S) islands (VI), bars (L, T and SB), vegetated bank (EK), dry channel (ED) and water depression (WD). Monsoonal water flow was considered an essential factor for reshaping GUs and supplying nutrients to GUs. A field study was carried out in low flow (dry/winter) season to validate the classification of GUs and to measure the nitrogen fixation rate in each type of GUs. Vegetation cover, soil/sediment moisture, bulk density, soil texture and elevation were determined for each GUs. Regression analysis showed that only bulk density and elevation significantly impact nitrogen fixation estimation and prediction can be improved using linear mixed models. Later on, based on seasonal variation of GUs, the distribution of nitrogen fixation was estimated in GUs in different seasons. Results showed that changes in the number and surface area of GUs across seasons could alter nitrogen fixation. This type of systematic investigation of the spatial and temporal distribution of geomorphological and nitrogen fixation rate measuring and monitoring will be useful for planning river restoration and ecosystem management programs.

Exponential utilization of Lithium-ion batteries (LIBs) has produced a notable amount of hazardous waste recently. The current practices focus on recovering precious metals available in cathode giving less priority for anode material (graphite) recoveries and valorizations. However, thinning of existing graphite ores, and extensive application of graphite for high tech industries made graphite to be a critical raw material to Europe recently. Accordingly, an attempt made to valorize black mass, after leaching out precious metals available in it. The batteries were physically processed, and the product was leached using 1mol/L, H2SO4 at 90°C for 90min with solid-liquid ratio 1/10. The remaining material was rich in graphite, which was used in this study. Three adsorption materials; Graphite Oxide (GO), Graphene Oxide (GrO) and Exfoliated graphite (EG) were made from the black mass to be used in organically contaminated wastewater treatment. After physical and chemical characterization, batch adsorption experiments were carried out separately for three different spiked organic contaminated (MO, MG, and MB) wastewater samples. Adsorption kinetics and isotherms were determined to conclude the best valorization option for the spent graphite available in black mass of LIBs. Accordingly, the study concluded that GrO to be the best option for spent graphite valorization.

An enriched culture of Polyhydroxyalkanoates (PHAs)-forming bacteria was developed using the liquid fraction (condensate) which is generated during drying and shredding of food waste. A mixed enriched culture was used for the production of PHAs, in two Draw-Fill Reactors (DFRs). The culture was developed using cyclic limitation by carbon and nitrogen. Urea was used as nitrogen source and a mixture of volatile fatty acids (VFAs), lactic acid, ethanol and glucose, simulating the composition of the condensate as carbon source. Two cycles of experiments were performed aiming to investigate the effect of the organic loading on the yields and composition of the produced PHAs.
The results showed that the organic loading did not significantly affect the accumulation capacity of PHAs, with the average yield for DFR-1 being 16±5% g PHAs/g DCW (dry cell weight) and for DFR-2 19±3% g PHAs/g DCW. The HV:HB ratio in DFR-1 was estimated to be (19±4):(81±4), whereas in DFR-2 (26±2):(74±2) indicating that the availability of more odd-VFAs may lead to the production of copolymers with higher HV content i.e. a bioplastic with improved properties.
