Derived by OpenAIRE algorithms or harvested from 3rd party repositoriesRobert Leconte in OpenAIREDischarges of combined sewer system overflows (CSOs) affect water quality in drinking water sources despite increasing regulation and discharge restrictions. A hydrodynamic model was applied to simulate the transport and dispersion of fecal contaminants from CSO discharges and to quantify the impacts of climate and population changes on the water quality of the river used as a drinking water source in Quebec, Canada. The dispersion model was used to quantify Escherichia coli (E. coli) concentrations at drinking water intakes. Extreme flows during high and low water events were based on a frequency analysis in current and future climate scenarios. The increase of the number of discharges was quantified in current and future climate scenarios with regards to the frequency of overflows observed between 2009 and 2012. For future climate scenarios, effects of an increase of population were estimated according to current population growth statistics, independently of local changes in precipitation that are more difficult to predict than changes to regional scale hydrology. Under “business-as-usual” scenarios restricting increases in CSO discharge frequency, mean E. coli concentrations at downstream drinking water intakes are expected to increase by up to 87% depending on the future climate scenario and could lead to changes in drinking water treatment requirements for the worst case scenarios. The greatest uncertainties are related to future local discharge loads. Climate change adaptation with regards to drinking water quality must focus on characterizing the impacts of global change at a local scale. Source water protection planning must consider the impacts of climate and population change to avoid further degradation of water quality.

Harvested from ORCID Public Data FileErik Meers in OpenAIREAbstract In the transition from a fossil to a bio-based economy, it has become an important challenge to maximally recuperate valuable nutrients coming from waste streams. Nutrient resources are rapidly depleting, significant amounts of fossil energy are used for the production of chemical fertilizers, whereas costs for energy and fertilizers are increasing. In the meantime, biogas production through anaerobic digestion produces nutrient-rich digestates. In high-nutrient regions, these products cannot or only sparingly be returned to agricultural land in its crude unprocessed form. The consequent processing of this digestate requires a variety of technologies producing lots of different derivatives, which could potentially be re-used as green fertilizers in agriculture. As such, a sustainable alternative for fossil-based mineral fertilizers could be provided. This study aims to characterize the physico-chemical properties of digestates and derivatives, in order to identify the fertilizer value and potential bottlenecks for agricultural re-use of these products, in line with European legislative constraints. In addition, the economic and ecological benefits of substituting conventional fertilizers by bio-based alternatives are quantified and evaluated. Waste water from acidic air scrubbers for ammonia removal shows potential for application as N-S fertilizer. Analogously, concentrates resulting from membrane filtrated liquid fraction of digestate show promise as N-K fertilizer. Substituting conventional fertilizers by digestate derivatives in different cultivation scenarios can result in significant economic and ecological benefits for the agriculturist. Starting from theoretical scenarios outlined in the current study, field test validation will be required to confirm the potential substitution of fossil-based mineral fertilizers by bio-based alternatives.

Harvested from ORCID Public Data FileColin R. Janssen in OpenAIREControlled flooding of lowlands is considered as a potential water management strategy to minimize the risk of flooding of inhabited areas during high water periods. However, due to industrial activities, river water, sediments and soils are often contaminated with metals which may have adverse effects on the ecosystem's structure and functioning. Additionally, salinity may greatly affect the bioavailability and toxicity of metals present or imported into these systems. The effect of contaminated soils under different flooding and salinity exposure scenarios on the growth, reproduction and metal accumulation in the oligochaete Tubifex tubifex (Müller, 1774) were examined. In these bioassays metal contaminated soils were flooded with water of different salinities (0 and 3 psu), and tested after 0, 6 and 12 months of permanent inundation. We indeed found that inundation time had significant decreasing effects on Cu and Zn accumulation; although initial accumulation of Cu and Zn was higher in the previously unflooded soil at the start of the flooding treatment, these differences seem to disappear after 6 months of permanent inundation. Moreover, the complex interaction between substrate type and salinity suggests that redox potential is probably of major importance.

Harvested from ORCID Public Data FileVanbroekhoven, Karolien in OpenAIREMicrobial fuel cells (MFCs) have gained a lot of attention in recent years as a mode of converting organic waste including low-strength wastewaters and lignocellulosic biomass into electricity. Microbial production of electricity may become an important form of bioenergy in future because MFCs offer the possibility of extracting electric current from a wide range of soluble or dissolved complex organic wastes and renewable biomass. A large number of substrates have been explored as feed. The major substrates that have been tried include various kinds of artificial and real wastewaters and lignocellulosic biomass. Though the current and power yields are relatively low at present, it is expected that with improvements in technology and knowledge about these unique systems, the amount of electric current (and electric power) which can be extracted from these systems will increase tremendously providing a sustainable way of directly converting lignocellulosic biomass or wastewaters to useful energy. This article reviews the various substrates that have been explored in MFCs so far, their resulting performance, limitations as well as future potential substrates.

Harvested from ORCID Public Data FileBaptiste Leroy in OpenAIREThis study was conducted with the aim of embedding circular economies (waste recycling) with photosynthetic biorefineries, for production of commercially viable by-products. Since nitrogen source constitute the major input costs for commercial Arthrospira sp. production, the use of nitrogen rich wastewater for Arthrospira sp. cultivation could significantly reduce their production costs. This study evaluated the effects of high concentrations (8.5-120 mM) of alternative nitrogen sources (urea, ammonium and nitrite) on the biochemical, pigment and proteomic profile of Arthrospira sp., under batch and continuous conditions. Arthrospira sp. cells fed with urea were quantified with modified biochemical and proteomic profile compared to the nitrate fed cells. No inhibitory effect of urea was observed on the biomass even at 120 mM. Nitrite fed cells exhibited comparable biochemical and proteomic profiles as nitrate fed cells. These results clearly indicated at the possibility of using urea rich wastewater streams for profitable cultivation of Arthrospira sp.

Consequently, agroecological practices are being increasingly adopted. Agroecological practices are biodiversity-based solutions that aim to generate sustainable and resilient agroecosystems, which could enhance the supply of ecosystem services. This study compared agroecological and conventional horticultural farms in terms of agroecological practices and ecosystem services supply. We conducted biophysical samplings and interviews on 24 agroecological and conventional farms over two summers in the Madrid Region (Spain). We used multiple indicators as proxies of the supply of 12 ecosystem services, and we identified the agricultural practices applied at each farm. We found that agroecological farmers applied more agroecological practices compared to conventional farmers, and agroecological farms had a higher potential to supply regulating, provisioning, and cultural services. Some agroecological practices, such as crop diversification, light tillage, and the use of organic pesticides, were associated with enhancing soil fertility, pest control, and pollination services. Our study provided empirical evidence that agroecological practices enhance ecosystem services at horticultural farms, which is extremely relevant to upscaling agroecology in the current context of ongoing European policy reforms.

Harvested from ORCID Public Data FileL. Gonsalvesh in OpenAIREAbstract Bulgarian coal sample from “Maritza East” lignite deposit, with a significant impact in the total energy supply for the country, is biodesulphurized on laboratory scale. In order to improve the desulphurization effect, sample under study is preliminary chemically treated, i.e. demineralized, depyritized and oxidized. For microbial treatment the microorganism Pseudomonas putida is applied. Maximum total (71.0%), pyritic (90.6%) and organic (49.4%) sulphur desulphurization effects are achieved as a result of combined action of chemical and microbial attacks. The protocol of Maritsa East lignite biotreatment by P. putida bacterial strain persisted on copious washing of the coal. During it, a high volume of dark brown coloured solution has accumulated. After solution acidification by HCl a voluminous precipitate has been formed. The appreciable quantity of this water soluble byproduct provokes us to pay special attention to that material. By applying AP-TPR technique coupled with different detection systems (MS and TD-GC/MS), organic sulphur alterations in chemically and microbiologically desulphurized lignite are assessed. Water soluble byproduct of biodesulphurized coal is also under consideration. It is revealed that as a result of biodesulphurization treatments significant part of S o is transformed in water soluble form, which is highly volatile under AP-TPR experimental condition. The ongoing biodesulphurization mechanism is oxidative with dominance of the C-atom oxidation. Since water soluble byproduct manifests external similarity to humic substances, it is compared to pristine humic acid obtained from the same coal sample. Analysis carried out demonstrates high similarity between both samples.

Maximum total (71.0%), pyritic (90.6%) and organic (49.4%) sulphur desulphurization effects are achieved as a result of combined action of chemical and microbial attacks. The protocol of Maritsa East lignite biotreatment by P. putida bacterial strain persisted on copious washing of the coal. During it, a high volume of dark brown coloured solution has accumulated. After solution acidification by HCl a voluminous precipitate has been formed. The appreciable quantity of this water soluble byproduct provokes us to pay special attention to that material. By applying AP-TPR technique coupled with different detection systems (MS and TD-GC/MS), organic sulphur alterations in chemically and microbiologically desulphurized lignite are assessed. Water soluble byproduct of biodesulphurized coal is also under consideration. It is revealed that as a result of biodesulphurization treatments significant part of S o is transformed in water soluble form, which is highly volatile under AP-TPR experimental condition. The ongoing biodesulphurization mechanism is oxidative with dominance of the C-atom oxidation. Since water soluble byproduct manifests external similarity to humic substances, it is compared to pristine humic acid obtained from the same coal sample. Analysis carried out demonstrates high similarity between both samples.

Harvested from ORCID Public Data FileAmadei Martínez, Luz in OpenAIREWe studied how changing human impacts affected phytoplankton dynamics in the freshwater and brackish tidal reaches of the Zeeschelde estuary (Belgium) between 2002 and 2018. Until the early 2000s, the Zeeschelde was heavily polluted due to high wastewater discharges. By 2008, water quality had improved, resulting in lower nutrient concentrations and higher oxygen levels. Since 2009, however, increased dredging activities resulted in altered hydrodynamics and increased suspended sediment concentration. The combined effects of these environmental changes were reflected in three marked transitions in phytoplankton community composition. Assemblages were dominated by Thalassiosirales and green algae (especially Scenedesmaceae) until 2003. The period 2003-2011 was characterized by the wax and wane of the centric diatoms Actinocyclus and Aulacoseira, while in the period 2012-2018 Thalassiosirales and Cyanobacteria became dominant, the latter mainly imported from the tributaries. Phytoplankton biomass increased sharply in 2003, after which there was a gradual decline until 2018. By 2018, the timing of the growing season had advanced with about one month compared to the start of the study, probably as a consequence of climate warming and intensified zooplankton grazing pressure. Our study shows that de-eutrophication (during the 2000s) and morphological interventions in the estuary (in the 2010s) were dominant drivers of phytoplankton dynamics but that the main shifts in community composition were triggered by extreme weather events, suggesting significant resistance of autochthonous communities to gradual changes in the environment.

Harvested from ORCID Public Data FileAlexis Sagastume Gutiérrez in OpenAIRESugar from sugarcane represents 65–70% of the world production of sugar and its production is mainly located in developing countries. The production process requires high amounts of steam and electricity at the different stages, and generates important quantities of residues. A major residue of the sugar production is filter cake (in Cuba: Cachaza), the residue from cane juice filtration. Filter cake causes significant pollution, and in several sugar factories it is considered a waste, posing problems of management and final disposal. This paper reviews recycling and recovery opportunities of filter cake (and bagasse) and experimentally studies the use of filter cake as fuel at the sugar factory. Filter cake may e.g. be used as a fertilizer/soil improver directly applied on the fields or after composting. During its decomposition, it generates, however, an acid leachate and emits significant amounts of greenhouse gases. Moreover, the experimental part of the paper shows that blends of filter cake with bagasse can be combusted in industrial boilers in sugar factories, and that loose, non-vitrified ashes with a similar appearance as bagasse ash are obtained. This results in lower volumes and masses of residues to be transported, so that transportation costs are reduced. Moreover, it gives a new economic value to the filter cake, and reduces its environmental impact. When all filter cake would be combusted blended with bagasse, about 25% more ash would be obtained than for bagasse and the trace element composition would comply with the regulatory limits for use as fertilizer/soil improver.
