Environmental negotiations are complex, and conveying the interaction between science policy in traditional teaching methods is challenging. To address this issue, innovative educational approaches like serious gaming role-playing games have emerged. These allow students to actively explore roles of different stakeholders environmental decision-making weigh for instance sometimes conflicting UN Sustainable Development Goals or other dilemmas. In work phosphorus negotiation game (P-Game)...
The purpose of our research is to evaluate the agroecological condition soils under long-term irrigation (over 50 years) and improve existing measures slow down degradation processes by introducing phosphogypsum. possibility simultaneously addressing ecological issue using large amounts phosphogypsum waste agronomic characteristics slowing or eliminating salinisation in irrigated has been studied justified. methodology was based on comparison different meliorative doses following conditions:...
Abstract This study evaluates the suitability of digestate from small mesophilic biogas plants in central Vietnam for agricultural application. Digestate samples were collected 85 farms and analyzed microbial contamination elemental composition. The presence pathogens was examined after anaerobic digestion under conditions impact antibiotic resistance microbes investigated. Potential integration solar energy into upgrading to biomethane also explored. Based on experimental data prior...
This paper focuses on the analysis of current cooperation trends in environmental protection research. A unified system interrelations between research methods field implementation bibliometric approach to review international taking into account consequences COVID-2019 pandemic was formed. To form a visualization analyzed data, special software product VOSViewer used. Five clusters were defined: green—international for assessing risks public health, particular biosafety and spread social...
The main idea was to justify the natural, technological, and ecological aspects of digestate-based composite for heavy metals (HMs) binding in soil due organic matter content mineral additives’ biosorption properties. study aimed determine potential a made from digestate phosphogypsum remediation HMs polluted soils role dissolved (DOM) HMs. Methods used included literature review identify mechanisms HM DOM, laboratory setup producing with (from manure or sewage sludge) mixed phosphogypsum,...
Abstract This research explores the potential for generating biogas and clean energy by processing organic waste, a process that can become sustainable solution to Syria's needs. Focusing on agricultural residues generated from citrus fruit orange, date, jujube cultivation in Syria, this study evaluates anaerobic digestion of these production. It highlights influence substrate composition optimization fermentation processes methane The focuses evaluating examining various dosages ranging 20%...
This paper investigates the influence of a phosphogypsum dump on surrounding environment (soil ecosystem) in Sumy region (Ukraine). Analysis soils was performed to study possible presence compounds leaching from dump. For physical chemical analysis samples, X-ray fluorescence (XRF) analysis, diffraction (XRD) and Fourier transform infrared spectrophotometry (FTIR) were used. XRF did not confirm contamination around dump, soil fluoride levels measured this comparable average concentration...
Abstract To expand the application of light‐weight and high‐strength polymer matrix composites in fields aerospace, shipbuilding transportation, it has designed fabricated a new‐type carbon fiber fabric/hollow glass beads/epoxy resin (CFF/HGB/EP) composite with three‐layer sandwich structure, consisting an upper layer (CFF/EP), core (HGB/EP) lower (CFF/EP). The effects CFF/EP HGB content on were explored through systematic investigation mechanical properties microstructure. results indicate...
The paper is focused on the research of biochemical treatment sewage sludge and phosphogypsum under sulphate-reducing conditions with a phosphorus release process. theoretical foundations work were based formalization using principles autocatalysis natural systems. During experimental for control physicochemical parameters process spectroquantic, X-ray fluorescence analysis other techniques used. A schematic model dephosphatation anaerobic stabilization was developed. increase dosage had...
This study aimed to improve the control system of biological stage wastewater treatment using quality information support concept environmental efficiency management. In this case, object was facilities Sumy city (Ukraine). For automatic quality, pH, oxidation reduction potential (ORP), electrical conductivity, and temperature indicators were taken, as well hydrobiological analysis activated sludge mathematical modelling. The pH at input has systematically unacceptable values (above 8.5...
Abstract Anaerobic digestion with simultaneous production of biogas is one the most common methods recycling, processing and decontamination organic waste to produce alternative fuels. A commonly used indicator sanitary safety substrate eggs Ascaris suum nematodes pigs, which are characterised by extremely high resistance environmental factors. The aim investigate effect mesophilic mode anaerobic on activity pathogens, particularly eggs. studied nematode species were placed in a installation...
The paper is focused on the research of applied aspects soil remediation, in particular process heavy metals (HM) binding and intensifying cultivation a microbiome using various organic-mineral compositions: biogenic composite, which product anaerobic transformation sewage sludge phosphogypsum; compost, based mixture phosphogypsum, superphosphate cattle humus; combination sodium humate superphosphate.The integration theoretical experimental principles synergy analysis interrelations system...
This study aims to evaluate the process of biogas production from droppings Clarias gariepinus under intensification methanogenesis using electrolysis pretreatment and electro-fermentation in comparison with addition stimulating substances (humates zeolites). For realization a series experiments, laboratory installations were developed. The following parameters monitored: composition, chemical oxygen demand, redox potential, hydrogen nitrates, ammonia–ammonium, nitrites. A taxonomic...
Abstract In this work, carbon nitride (C 3 N 4 ) powder was oxidized by the Hummers oxidation method, and (O‐C obtained. Epoxy (EP) modified with O‐C , then fiber fabric/epoxy (CF/EP) composites were prepared hand‐pasting molding.
