PFAS, PCBs, PCDD/Fs, PAHs and extractable organic fluorine in bio-based fertilizers, amended soils and plants: Exposure assessment and temporal trends

Bio-based fertilizers (BBFs) produced from organic waste contribute to closed-loop nutrient cycles and circular agriculture. However, persistent organic contaminants, such as per- and poly-fluoroalkyl substances (PFAS), polychlorobiphenyls (PCBs), polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), as well as polyaromatic hydrocarbons (PAHs) can be present in organic waste or be formed during valorization processes. Consequently, these hazardous substances may be introduced into agricultural soils and the food chain via BBFs. This study assessed the exposure of 84 target substances and extractable organic fluorine (EOF) in 19 BBFs produced from different types of waste, including agricultural and food industrial waste, sewage sludge, and biowaste, and through various types of valorization methods, including hygienization at low temperatures (<150 °C) as well as pyrolysis and incineration at elevated temperatures (150–900 °C). The concentrations in BBFs (ΣPFOS & PFOA: <30 μg kg−1, Σ6PCBs: <15 μg kg−1, Σ11PAHs: <3 mg kg−1, Σ17PCDD/Fs: <4 ng TEQ kg−1) were found to be below the strictest thresholds used in individual EU countries, with only one exception (pyrolyzed sewage sludge, Σ11PAHs: 5.9 mg kg−1). Five BBFs produced from sewage sludge or chicken manure contained high concentrations of EOF (>140 μg kg−1), so monitoring of more PFAS is recommended. The calculated expected concentrations in soils after one BBF application (e.g. PFOS: <0.05 μg kg−1) fell below background contamination levels (PFOS: 2.7 μg kg−1) elsewhere in the literature. This was confirmed by the analysis of BBF-amended soils from field experiments (Finland and Austria). Studies on target legacy contaminants in sewage sludge were reviewed, indicating a general decreasing trend in concentration with an apparent half-life ranging from 4 (PFOS) to 9 (PCDD/Fs) years. Modelled cumulative concentrations of the target contaminants in agricultural soils indicated low long-term risks. Concentrations estimated and analyzed in edible plant part were low, indicating that exposure by plant consumption is well below tolerable daily intakes.

These preliminary results showed excellent performance of the electrodes, showing their potential for use in MFCs in an economical way.

Waste-to-Energy in the Circular Economy Transition and Development of Resource-Efficient Business Models

The consistent rise of the per capita waste generation rate has led to an escalation of waste quantities and the need to expand waste disposal methods. Efforts to develop clean and affordable energy systems are increasingly linked to waste-to-energy as part of the transition to a circular economy (CE). A resource-efficient waste-to-energy business model within a CE offers a variety of environmentally friendly waste management options based on their overall environmental impacts but also makes efficient use of available resources and technologies to convert different types of waste into energy, which helps reduce the adverse effects on the environment and create additional energy sources. This research aims to identify innovative waste management solutions to foster the implementation of CE and a more resource-efficient business model. The research methodology is based on qualitative and quantitative research, triangulation, material flow assessment, and systems dynamics. The value of this study is within the analysis of existing waste-to-energy plant case studies to identify a set of recommendations and appropriate business models for the countries that are at an early stage of evaluation of such facilities. This study found that waste-to-energy plants are critical to achieving the EU’s waste disposal targets by 2035. The findings highlight the importance of supporting mechanisms in the waste sector, such as structural funds, as the industry primarily focuses on societal health and safety and environmental protection, alongside resource efficiency and circularity potential.

The 3d shape detection is done after analyzing the image by YOLOv8 model based on GLPN neural network.

The Importance of Responsible Electronic Waste Treatment for Sustainability

Waste production is experiencing a significant increase in correlation with the growth of the human population and industrial activities. The kind of waste that is expanding at a rapid rate is known as "e-waste," which stands for electronic waste. In the context of electronic waste, the term refers to the waste produced during the disposal of electronic devices and any other components utilized in making or operating these devices. In the same way that different types of waste occur, electronic waste pollutes the environment and the human population. Electronic waste seriously threatens ecosystems and human health if not properly disposed of. The quantity of e-waste generated on a global scale is increasing continuously due to the short lifetime of electronic devices and the fast advancement of technology. Developing sustainable treatment methods for electronic waste is critical to address this issue. Valuable materials are utilized to fabricate electronic devices to enhance their functionality, longevity, conductivity, and efficacy. To mitigate pollution, recycling electronic waste is an absolute necessity due to the factors above. Although this fact remains true, numerous organizations exhibit reluctance towards recycling their electronic devices due to apprehensions regarding the potential exposure of sensitive information. Conversely, secure data deletion is now a reality due to the continuous development of technological capabilities.

A review on bacterial enriched vermicompost and its applications

Generation of the massive quantity of solid waste around the globe is a major ecological and technical problem. Vermicomposting may be the viable option to handle solid waste in an environmentally friendly way. Vermicompost have higher level of available nutrients like carbon, nitrogen, phosphorous and potassium, calcium and magnesium which are derived from the wastes. Many researchers have attempted to evaluate for development of efficiency vermicompost by using varieties of earthworms. The use of earthworms in the degradation of different types of wastes is continuing from the past so many years. These wastes include industrial, agricultural of plant debris and domestic waste papers and cattle dung. Fixed nitrogen is a limiting nutrient in most environments, with the main reserve of nitrogen in the biosphere being molecular nitrogen from the atmosphere. Molecular nitrogen cannot be directly assimilated by plants, but it becomes obtainable through the biological nitrogen fixation process that only prokaryotic cells have developed. Vermicompost is an effective carrier for bacterial growth so that the symbiotic bacterial species such as Mycorrhiza and Dyaztotor of helps in the rapid growth of plant while Azotobactor, Rhizobium involves in the fixation and storing of nitrogen for plants. This review focus on the vermicomposting and microbial enrichment of vermicompost for the exceed crop production.

The impact of circular economy strategies on municipal waste management: A system dynamics approach

The low levels of reuse and recycling of solid waste in cities in developing countries can be attributed to decision-making processes with sub investment that do not consider waste streams, recovery capacities, and potential for recycling. This is due to a lack of understanding of the systemic structure of urban waste management.This article presents the development of a model of an urban waste management system that integrates decisions based on strategies that close cycles, belonging to the concept of a circular economy. These strategies aim to increase the potential use of organic waste, plastics, and glass.The model was built using the Systems Dynamics methodology, which allows obtaining mathematical models for the study and observation of trends and future scenarios of complex systems. The model is made up of three modules: health, financial, and circular economy. The strategies evaluated and compared in the simulation environment were: Economic incentives at the price of the material used; Increase in waste sorting capacity; Increase in the capacity to use waste.Methodologically, novel mathematical representations were achieved for the estimation of the useful life of sanitary landfills. Likewise, a mathematical formulation was found for the automatic evaluation of the efficiency in the capacity to use different wastes, which allows to know the need for investment or increase of capacity to use the type of waste evaluated.Using novel mathematical representations, this study achieved a methodological breakthrough in estimating the useful life of sanitary landfills and waste transformation efficiency. These representations also enable the automatic evaluation of how effectively different types of waste can be utilized. This information can then be used to determine the need for investment in, or expansion of, the capacity to handle specific waste types or to increase the overall waste collection capacity of the city.

Microbial Pollution with Antibiotic Resistant Bacteria in the Buriganga River of Dhaka, Bangladesh

Dhaka, the capital of Bangladesh, is located on the bank of the Buriganga River. Pollution of Buriganga river water with different types of waste containing antibiotic-resistant (AR) bacteria poses a threat to human health. Therefore, this study aims to analyze the physicochemical parameters, total aerobic bacterial count (TBC), total coliform count (TC), and antibiotic-resistant bacteria from waste disposal points located in the river seasonally. We collected 59 water samples from sewage waste (SW), 31 from industrial waste (IW), and 9 from hospital waste (HW) disposal sites during the wet (November to April) and dry (May to September) seasons in the Buriganga river. We found that water temperature, pH, BOD, and COD decreased, but water total dissolved solids (TDS) increased significantly in the dry season compared to the wet season. Bacteriological analysis showed that total TBC and TC were significantly increased in the dry season compared to the wet. Further analysis showed that TBC and TC from the water of SW and HW disposal sites increased in the dry season compared to the wet. However, TBC and TC from the water at IW disposal sites were not changed. These results indicate that SW and HW are the main contributors to the bacterial coliform contamination in the Buriganga River. Escherichia coli, Pseudomonas spp., Staphylococcus aureus, Streptococcus spp., and Salmonella spp. isolates showed a high prevalence of resistance against commonly used antibiotics. It can be concluded that SW and HW might spread AR bacteria in the water of the Buriganga River, which causes a significant threat to humans and the environment.

Suitability and characterization of pumice, bauxite, and ferrochrome slag as alternative raw materials in vitrified ceramic industry

Since the natural raw materials used in the manufacture of clay-based ceramic products vary greatly in the sintering stage, the resulting products are quite heterogeneous. In addition, different types of waste could be used to make ceramic tiles and bricks. Therefore, this study aimed to investigate the effects of pumice, bauxite, and ferrochrome slag on the vitrified ceramic body. In this context, firstly, binary slip mixtures were prepared by composing 40% clay with 60% pumice, bauxite, and ferrochrome slag one by one, which was reduced to 150 µm in particle size. Then, the mixtures were shaped by slip casting method and sintered at 1000°C, 1100°C, 1200°C, and 1250°C. The qualitative XRD analysis was performed in order to see the phase variation, and physical properties were determined with shrinkage and water adsorption measurements. Since pumice transformed into a glassy phase after sintering at 1100°C, an amorphous phase was observed in all samples produced with pumice. In addition, the mullite development occurred in clay-pumice body composition with the temperature increment. However, tridymite and cristobalite phases were analysed in clay bauxite and ferrochrome body compositions. The shrinkage and water adsorption values, which were high in the samples sintered at 1000°C, began to reduce from 1100°C to 1250°C significantly. In particular, water adsorption reached 0% in the clay-pumice system which was suitable for a fully vitrified-high density standard (ISO13006-10545/98). Besides, the brighter colour was reached in the clay-pumice system while brown and black colour was seen in clay-bauxite and clay-ferrochrome bodies, respectively.

Experiments Using Different Types of Waste to Manufacture Ceramic Materials: Examples on a Laboratory Scale

Reusing waste as raw materials to produce other materials can entail a decrease in production costs and in the abusive use of natural resources. Furthermore, it can even improve the properties of the end product or material. In this sense, a review of the most relevant literature published in recent decades shows that numerous solutions have been proposed or implemented, such as its use to produce construction materials, catalysts, pigments, pozzolana, refractory materials, glass-ceramic products, etc. Our research group has verified the viability of using different types of waste as secondary raw materials to obtain several types of ceramic, glassy and glassceramic materials, as well as frits. This article highlights several types of industrial waste that have both non-toxic (Li, Ca and Mn) and highly toxic (Cr VI) differentiating elements that can be used in sintering and vitrification industrial processes to immobilise them or render them inert. We studied the compositions and characterised the various materials obtained, conducting toxicity and leaching tests on waste/materials designed with high amounts of chromium. A suggestion for future lines of research has been proposed.

Knowledge level of farmers of Dharwad district towards farm waste management

Farm waste is a serious economic, environmental and social problem. There is a need to analyze different types of waste produced in production, processing and management practices for better utilization of agricultural waste materials. Farm waste management helps framers to reduce cost on fertilizers and increasing yield of crops. Farm waste conversion reduces waste flow into air, water and reduces greenhouse gas emissions such as carbon dioxide and nitrous oxide. An exploratory research design was used to know the knowledge level of farmers towards management of farm waste in the selected talukas of Dharwad district. From Dharwad district Dharwad and Kundgol taluka were selected. In total 120 farmers were selected through purposive random sampling technique. The data was analyzed by using suitable statistical tools. The results revealed that majority (90.00%) of the farmers in both Dharwad &amp; Kundgol taluka had fully aware that farm waste includes crop waste, domestic waste and livestock waste followed by more than 75 per cent of the farmers were fully aware about utilizing farm waste and that will increase their crop yield. About 80 per cent of the farmers were aware that the farm waste can be used for production of different products. While very few of the farmers (37.00%) fell in low knowledge category. It could be concluded that, all the crop wastes are placed in the right time and right place for best utilization in order to convert into useful products and control of pollution by proper waste management

Experimental investigation on mechanical properties of sustainable roller compacted concrete pavement (RCCP) containing waste rubbers as alternative aggregates

Different types of solid waste are generated every year due to global industrialization. With the rapid growth of the automobile industry, the disposal of billions of waste rubbers (WR), which pollute the environment and cannot be disposed of properly, is emerging as an urgent matter of concern. Recycling waste rubbers by using them on pavements will contribute to the elimination of ecological and economic problems. In this study, the effects of waste rubbers on the mechanical properties of roller-compacted concrete pavement (RCCP) were investigated by obtaining sustainable RCCP mixtures using different types of waste rubbers as coarse and fine aggregate substitutes. In this context, waste rubbers with three different sizes (powder, crumb and shredded) were substituted for aggregate by volume at seven levels (0%, 2.5%, 5%, 7.5%, 10%, 20% and 30%) with a maximum of 30% in RCC mixtures. Unit weight, mechanical properties, modulus of elasticity and ultrasonic pulse velocity (UPV) were evaluated and compared according to the waste rubber content in the RCC mixtures. In addition, microstructural analysis of the mixtures was performed through scanning electron microscopy (SEM). The experimental results revealed that the compressive, flexural and splitting tensile strength and modulus of elasticity decreased with increasing waste rubber content in RCC. The utilization of waste rubber increased the ductility of RCC and decreased the density to produce lighter concrete. RCC with a compressive strength of about 30 MPa could be obtained by substituting 10% of waste rubber for aggregate. Thus, the utilization of high waste rubber content in pavements was feasible. This study can contribute to a more sustainable RCCP production by replacing natural aggregates with waste rubbers.

The Contribution of Open Source Software in Identifying Environmental Crimes Caused by Illicit Waste Management in Urban Areas

This study focuses on the analysis, implementation and integration of techniques and methods, also based on mathematical algorithms and artificial intelligence (AI), to acquire knowledge of some phenomena that produce pollution with an impact on environmental health, and which start from illicit practices that occur in urban areas. In many urban areas (or agroecosystems), the practice of illegal waste disposing by commercial activities, by abandoning it in the countryside rather than spending economic resources to ensure correct disposal, is widespread. This causes an accumulation of waste in these areas (which can also be protected natural areas), which are then also set on fire to reduce their volume. Obviously, the repercussions of such actions are many. The burning of waste releases contaminants into the environment such as dioxins, polychlorinated biphenyls and furans, and deposits other elements on the soil, such as heavy metals, which, by leaching and percolating, contaminate water resources such as rivers and aquifers. The main objective is the design and implementation of monitoring programs against specific illicit activities that take into account territorial peculiarities. This advanced approach leverages AI and GIS environments to interpret environmental states, providing an understanding of ongoing phenomena. The methodology used is based on the implementation of mathematical and AI algorithms, integrated into a GIS environment to address even large-scale environmental issues, improving the spatial and temporal precision of the analyses and allowing the customization of monitoring programs in urban and peri-urban environments based on territorial characteristics. The results of the application of the methodology show the percentages of the different types of waste found in the agroecosystems of the study area and the degree of concentration, allowing the identification of similar areas with greater criticality. Subsequently, through network and nearest neighbour analysis, it is possible to start targeted checks.

Detritiation of the Organic Material in the MSO Process

Tritium is a radioactive isotope of hydrogen, and due to its limited supply and related high price, it is necessary to recover it from tritiated materials via detritiation technologies. The number of tritiated materials arises during fusion. Tritium from fusion reactors is deposited in the outer layer of plasma-facing materials, which must be dealt with during maintenance or decommissioning processes. A second source of waste is laboratory equipment that could be contaminated with tritium. High-temperature treatment in an oxidation environment can achieve the release of tritium from metals or organic materials. The tritiated vapor is then captured in a series of water bubblers and reprocessed into pure T2. One of the high-temperature methods is molten salt oxidation (MSO), which uses high temperatures, alkaline salt, and an oxidative environment for flameless oxidation of different types of waste. This work aimed to simulate the detritiation processes of tritiated organic materials in MSO technology. First, a series of experiments with D2O absorbed in ion resins was conducted. The organic waste was decomposed within the molten salt, and the flue gas was measured to determine the oxidation efficiency. The D2O was captured in a series of water bubblers, and the water was then analyzed with attenuated total reflectance (ATR)–Fourier transform infrared spectroscopy (FTIR). The results showed that all deuterium in the form of D2O was caught in the first water bubbler. The capture efficiency ranged from 22.32% to 61.13%. The lower efficiency capture can be explained as D2O in water can form a HDO molecule and its correct determination is problematic. The second type of experiment was carried out with T2O with an activity of 851 Bq and with tritiated oil with an activity of 2495 Bq. The T2O was added to the set amount of ion resins and dosed into MSO. A peristaltic pump dosed the tritiated oil. The flue gas was measured to determine oxidation efficiency, and the T2O was captured within the water bubblers. The water was analyzed with liquid scintillation spectroscopy. The capture efficiency ranged between 76.42% to 97.87%. The results showed that this technology is suitable for the detritiation of tritiated organic materials.

Analysing Plastic Pollution: A Case Study of Coastal Pollution from Inland Urban Waterways in Galle City, Sri Lanka

The coastal stretch of Galle city is currently facing an acute pollution with the aggregation of various types of waste on beaches due to malpractices of the community living around the coastal as well as inland areas of the country. Rivers or canals play a key role in the transport of wastes from source to sea and are estimated to emit around 1 metric ton of plastics into the ocean annually. Mainly five sea outfalls are existing along the Galle coastal zone and those transfer various waste towards the beaches. The present case study aims to identify the coastal pollution caused by inland waterways in Galle municipal council area and to detect the main plastic pollutants flow into coastal zone through inland waterways from month of April to June 2023. The waste trap constructed at the main inland waterway located at Galle municipal council area, the Moda Ela trapped different types of waste and the CCTV camera fixed directing to the above-mentioned canal, captures images, uploaded to a cloud system and feed the data to an Artificial Intelligence model to detect the litter type and their counts which flows along the canal daily and get recorded in the smart plastic litter monitoring web-based system using feature extraction techniques in AI. This smart system has mainly identified the count of plastic fragments, plastic bottles, Styrofoam, and trash bags separately, as the main pollutants of this canal and has interpreted graphically and numerically in the smart system which can be freely accessed. Weights of waste were taken manually. Finally, recorded counts of waste in the smart system emphasis that most abundant causative agent affected on pollution of Moda Ela was plastic bottles (58%) while effect of Styrofoam and trash bags were 34% and 8% respectively. Further, average weight of plastic bottles was recorded highest during the study period (130 kg) when compared to other waste categories. According to the results, plastic bottles have become the main source of pollution comes through inland canals which contribute to coastal pollution. Visual observations further convince that the highest pollution source was Moda Ela while less contribution was from Mahamodara canal. The present study highlights plastics as the main pollutants in inland waterways which effect on coastal pollution. Therefore, it is necessary to identify the polluters and need to implement proper rules and regulations while suggesting any alternatives for plastics.&#x0D; &#x0D; Keywords: Coastal pollution, Inland waterways, Waste trap, Galle Municipal Council area, Artificial intelligence technology

Life cycle analysis (cost and environmental) of different renewable natural gas from waste procedures based on a multivariate decision-making approach: a comprehensive comparative analysis

Abstract This article presents a framework that focuses on structural considerations within gas networks to evaluate and rank various feasibility options for renewable natural gas (RNG) cases. Specifically, the analysis examines and compares a range of methods for producing RNG using natural gas from waste (NGFW), considering different types of waste as feedstock. To analyze and evaluate the different methodologies, the article uses a decision architecture based on life cycle analysis (cost and environmental). These tools are used to determine the most favorable path for the NGFW process. The preferred pathway is identified by considering a range of decision scenarios that take into account variables such as geographical conditions, the availability of various feedstocks and the different stakeholders’ priorities. The results show that according to the economically neutral scenarios and those that favor economic considerations, the pathway involving RNG generation from landfill gas coupled with a pressure swing adsorption (PSA) upgrading technology emerges as the optimum choice. Conversely, in a scenario where environmental sustainability is a priority, the process that emerges as most advantageous is the use of animal manure with the addition of a PSA upgrading unit. The designed structure can be adapted to different regions, each with its own unique geographical features and feedstock resources, and can be customized to meet the varying interests of stakeholders. Based on both parametric assessments and analytical interpretations, this article not only identifies optimal pathways but also provides a set of recommendations and strategies aimed at improving economic behavior.

Development of Management Systems for Sustainable Municipal Waste Management Systems

Waste Management Systems. are designed to efficiently handle and process waste materials generated by human activities. These systems are crucial for minimizing environmental impacts, promoting sustainability, and protecting throughout its lifecycle, from its generation to its final disposal or recycling. Here is an overview of the key components and processes involved in waste management: Waste Generation: Waste can be generated from various sources, including residential areas, commercial establishments, industries, and construction sites. It encompasses solid waste (such as household waste and packaging materials), liquid waste (such as wastewater and sewage), and hazardous waste (such as chemicals and medical waste). Waste Collection: its source. This involves the placement of collection bins or containers at strategic locations, regular pick-up schedules, and specialized collection vehicles for different types of waste. Waste Segregation: After collection, waste is often sorted and segregated based on its type and characteristics. This helps in the efficient management of different waste streams, enabling appropriate treatment or disposal methods. Segregation can be done at the source (e.g., separating recyclables from non-recyclables) or at dedicated facilities. Future vehicular organizations are supposed to send more limited distances the car employer. Client-server methods revel in decrease execution regardless of standard abnormal network. Another one the worldview of shared content dispersion over the Web is arising with swarm conventions. The objective of Web amassing conventions is to lessen the heap on satisfied servers. Waste Treatment: Waste treatment involves various processes aimed at reducing the volume and toxicity of waste, as well as recovering valuable resources. Common treatment methods include composting, incineration, landfilling, and biological or chemical treatment of wastewater. Advanced technologies, such as anaerobic digestion and plasma gasification, are also used for waste conversion. Recycling and Resource Recovery: Recycling plays a crucial role in waste management systems. Materials like paper, plastics, glass, metals, and electronic waste can be recycled and sent to landfills or incinerators. Resource recovery also involves the extraction of energy from waste, such as through waste-to-energy (WTE) facilities. GWP Uppsala WMS,GWP Uppsala CS, GWP Alvdalen WMS, GWP Alvdalen CS, AP Uppsala WMS. IncAll, Inc90%, BioBus, RecPl. From the result it is seen that GWP Uppsala CSis got the first rank where as is the GWP Alvdalen CSis having the lowest rank. GWP Uppsala CSis ranked first and industrial building is ranked lowest.

A Laboratory Trial on the Usability of Waste Impregnated Papers in Standard Quality High Density Fiberboard (HDF) Production

The aim of this study is that determination of the usability of the different types of waste impregnated papers (IP) in a standard HDF production line. For this purpose, the HDF panels were produced from industrial prepared fibers and waste of IP, called decor and overlay, preparation lines by three different ratios (from 5% to 15%). Some important properties of HDF’s were determined according to standard test methods and were evaluated by statistical analysis in a 95% confidence interval. According to the evaluation results, it was concluded that it is possible to statistically evaluate the use of overlay and decor papers up to 15% in a standard production in terms of density, and equilibrium moisture, thickness swelling (2 h and 24 h), and modulus of rupture values. In addition, it was observed that the modulus of elasticity and tensile strength values generally improved as the amount of waste paper increased, regardless of the type of waste paper. However, the significant increase in formaldehyde emission showed that evaluating these waste papers without changing in the standard production line is difficult.
