Gas migration at the granite–bentonite interface under semirigid boundary conditions in the context of high‐level radioactive waste disposal

AbstractThe corrosion of waste canisters in the deep geological disposal facilities (GDFs) for high‐level radioactive waste (HLRW) can generate gas, which escapes from the engineered barrier system through the interfaces between the bentonite buffer blocks and the host rock and those between the bentonite blocks. In this study, a series of water infiltration and gas breakthrough experiments were conducted on granite and on granite–bentonite specimens with smooth and grooved interfaces. On this basis, this study presents new insights and a quantitative assessment of the impact of the interface between clay and host rock on gas transport. As the results show, the water permeability values from water infiltration tests on granite and granite–bentonite samples (10−19–10−20 m2) are found to be slightly higher than that of bentonite. The gas permeability of the mock‐up samples with smooth interfaces is one order of magnitude larger than that of the mock‐up with grooved interfaces. The gas results of breakthrough pressures for the granite and the granite–bentonite mock‐up samples are significantly lower than that of bentonite. The results highlight the potential existence of preferential gas migration channels between the rock and bentonite buffer that require further considerations in safety assessment.

Numerical assessment of the time-dependent behaviour of a tunnel with a yielding support system for a potential repository in claystone

For the disposal of heat-generating radioactive waste and spent fuel in claystone formations, support structures for underground excavations are essential for the operational safety of geological disposal facilities (GDF). Claystone formations of moderate strength, at considerable depths, are characterised by their squeezing, creeping, and, sometimes, swelling behaviour that results in continuous tunnel convergence over time. Under these conditions, a rigid support system can be subjected to very high loads, requiring a considerable thickness and/or high-performance concretes. Therefore, yielding support systems are being currently investigated as a promising alternative for GDF. This work presents a numerical study of the behaviour of a tunnel in a claystone formation with a yielding support system. The use of a compressible mortar between the rock and the lining is assumed, as a means of reducing loads and mitigating the effects of creep deformations. A key aspect of the analyses is that the host rock is characterised by a constitutive model that includes a number of features that are relevant for the satisfactory description of the hydro-mechanical behaviour of stiff clayey materials, such as mechanical anisotropy, creep, strain softening, and its ability to simulate localised deformations through a nonlocal regularisation. An elastoplastic constitutive model was also developed to represent the behaviour of the compressible mortar. Results provide relevant insights into the performance of the adopted yielding support system, particularly regarding the effect of time-dependent deformations and the additional relaxation of the rock on the fractured zone near the excavation.

Scenario Analysis of Food Phosphorus Footprint in Kisumu, a Lakeside East African City in Lake Victoria (Kenya).

Increased food production and consumption patterns have resulted in higher urban food phosphorus footprints, leading to a series of resource and environmental problems worldwide. We quantified the food phosphorus footprint of the African city of Kisumu using substance flow analysis. Our aim was to develop Kisumu's sustainable phosphorus management framework so that the city would reduce phosphorus losses into the food system. Our results show that in the year 2023, the import and export of food phosphorus in the Kisumu food system was 2730.26 ± 2.7% t P yr-1 and 3297.05 ± 2.4% t P yr-1, respectively. There was -566.79 ± -18% t P yr-1 food phosphorus deficit in the Kisumu food system. Crop planting subsystem runoff/leaching/erosion loss, household consumption subsystem waste loss, and pit latrine subsystem blackwater loss are the major pathways of phosphorus losses into the environment and the main contributors to the food phosphorus footprint in the city. The 2030 scenario analysis shows that implementing a comprehensive scenario scheme throughout the entire lifecycle process from phosphorus input to waste disposal is the best choice for reducing phosphorus losses and suppressing the growth of food phosphorus footprint in the future. Our study shows that the food phosphorus footprint in the Kisumu food system was 0.67 kg P cap-1yr-1 in 2023, which is still at a low level but may enter a continuous upward trend with the improvement of socio-economic development of the city. In our framework, we have proposed a few essential measures that include urine separation, installation of septic tank, adjustment of dietary structure, flexible layout of sanitary disposal facilities, and separation of organic waste streams to reduce food phosphorus footprints in Kisumu. Given the similarity of cities along the shores of Lake Victoria, our calculation methods and management strategies can be applied to other cities in the region.

The Effect of Pollutantmigration on the Environmental Situation in the Zone of Chemical Weaponinfluence

The article is devoted to the issues of monitoring the environment state in the influence zone of chemically hazardous objects on the example of the environmental monitoring system of a chemical weapons storage and destruction facility (CWDF) in the city of Kambarka, Udmurt Republic. Among the components there are: production control systems and site monitoring, environmental monitoring and health monitoring, however, it is environment in the zone of the chemical waste disposal facility influence which hasthe largest area and is the most difficult to control. Here, due to large areas, the process of migration of pollutants over considerable distances is observedclearly. The importance of the system for arranging sampling points on the topographic map of the waste disposal facility is shown in order to take into account the process of pollutantmigration. Vertical and horizontal migration of pollutants can lead to the emergence of unobvious local areas of pollutantaccumulation both within and outside the influence zone of the chemical waste disposal facility. A solution to the problem of migration process modeling on a conditionally selected area of the territory within the facility influence zone is presented to show the effect pollutantmigration on the dynamics of the environmental situation within the chemical waste disposal area. It has been proven that within the area under consideration there will be a significant amount of pollutant, which, subject to further evaporation of rainwater runoff, will remain in this area. This indicates the inevitability of the appearance of local areas of pollutantaccumulation in the influence zone of chemically-disposable substances in excess of permissible standards for their concentration, which requires a revision of the arranging sampling pointsystem, taking into account the application of migration processmodeling methods. The need for dynamic observations in individual sites of the area, selected with respect to the analysis results of the pollutantmigration routes within the entire influence zone of the chemically-disposable waste disposal facility, in order to assess the degree of impact of the non-toxic waste disposal facility on the environment, is substantiated.

Penerapan Fungsi Retribusi Pasar Terhadap Layanan Infrastruktur Pedagang Pasar Tradisional di Desa Batetangngga (Perspertif Hukum Ekonomi Islam )

The research investigates the traditional market levy in Batetangngga Village from an Islamic legal perspective. The aim of this study is to understand the function of market levies in providing trading facilities in the market. With two problem formulations: 1) how is the application of traditional market levies in Batetangngga Village, 2) How is the economic legal review of traditional market levies in Batetangngga Village. This research is qualitative using interview and observation techniques, and the data processing and analysis methods used in compiling this thesis are editing and verification. The results show that market levies in traditional markets come from the collection of business rental fees, cleanliness levies, electricity levies, and parking levies. These levies vary for each trader and are divided into several groups. Facilities available in Batetangngga Village traditional market include toilets, parking areas, and waste disposal facilities. The collection of levies in this traditional market does not comply with Islamic economic law because there are conditions not met by market officials, namely responsibility for repair and maintenance. However, market officials are not responsible for repairing facilities that have been paid for by traders. Taking away others' rights and causing harm to traders whose rights are taken is akin to stealing others' property. Taking someone else's rights is tantamount to committing injustice, a prohibition mentioned in the Qur'an and the Hadith of the Prophet.

MINERALOGICAL AND GEOCHEMICAL PARAMETERS OF SNOW COVER WITHIN THE ANTHROPOGENICALLY DISTURBED SITES OF THE NADYM-PUR INTERFLUVE (NORTHERN PART OF WESTERN SIBERIA)

The article analyzes the content of metals in solid aerosols and snow water sampled in the anthropogeni-cally disturbed and background sites of the Nadym-Pur interfluve. The results of microscopic studies of solid aerosols showed the presence of secondary minerals, technogenic formations, as well as a large amount of pyrite in samples from the eastern part of the study area. The maximum concentrations of metals in solid aero-sols were found in snow of the sanitary protection zones of waste disposal facilities, with the exception of Ca, which prevails in snow cover of Novy Urengoy (up to 10% of dry matter). The urbanized area is characterized by the highest values of dust load (up to 111 mg/m2 a day). The local contamination with Ba within the waste landfills in Novy Urengoy is associated with the sites of barite and drilling waste processing. We applied the factor analysis to identify the main metal associations characteristic of solid aerosols from different functional zones: Ca-Co-V-Mn (city), Ba-Sr-K-Na and Cd-Cu-Pb (waste disposal sites), Cu-Ni-Cd (the entire studied area). Based on the study of the content of dissolved forms in snow water, a high mobility of metals in the northern landscapes and its decrease in urban environment were revealed. The mineralogical and geochemical analysis of snow suggests the influence of the Norilsk industrial region on the eastern part of the Nadym-Pur interfluve, Zn, Cu, Ni, Pb and the mineral pyrite being the indicators. The risks of environmental pollution under the aerotechnogenic transport are associated with high content of Zn, Cu, Ni, Pb and Ba in solid aero-sols. The calculation of the Toxicity Probability Index (MERMQ) showed that some aerosol samples from the landfill sites have a high probability of biological effects. Using data on the chemical composition of soils and soil water, no visible effect of snow pollution on the growth of metal concentrations in soil and soil water was revealed, with the exception of local contamination with Ba, which led to a twofold increase in the content of the metal in the upper soil horizon.

Evaluation of Different Fly Ash-Blast Furnace Slag Formulations for Design of Geopolymers in Radioactivity Disposal Applications

Geopolymers in radioactive waste management have in recent times gained dominance in disposal module acceptance. Here is a comparative study on formulations prepared from industrial wastes to be utilized as radionuclide disposal barriers in near surface disposal facilities (NSDFs). Different tools such as isocalorimetry, compressive strength, chemical durability were utilized for screening the formulations. Water leaching of the samples shows that the release of the ions to the leachant is minimal. Durability studies in acids (H2SO4, HCl and HNO3) show that the samples are mostly acid resistant. X-ray tomography suggests low pore volume change over a period of 2 years. The study concludes that the NSDF requirement of low permeability of water and better chemical durability criterion is met by the optimized geopolymerization formulation.

USERS’ SATISFACTION WITH INTERCITY BUS TERMINAL QUALITY IN LAGOS STATE, NIGERIA

Globally, efficient intercity public transport relies on well-designed and high-quality terminal facilities and services to enhance accessibility, mobility, and safety for passengers and freight. Despite governmental efforts, bus terminals in Nigerian urban areas are becoming hotspots for unregulated activities and traffic chaos. In response, this study investigates users’ satisfaction with Lagos State's intercity bus terminal quality, analysing socio-economic profiles, satisfaction levels with quality of terminal facilities (QoTF) and services (QoTS), and challenges impacting terminal operations. Using a cross-sectional survey, 200 questionnaires were distributed to terminal users, employing a multistage sampling technique. Descriptive (weighted mean analysis) and inferential (multiple linear regression [MLR] analysis) statistics were employed for data analysis. Results indicate that the majority of respondents are male, aged below 40, and permanent terminal users. Satisfaction is noted with 13 out of 24 parameters of QoTF, with top-ranking parameters including parking space, restaurant facilities, and waste disposal facilities. However, dissatisfaction is expressed with 8 out of 14 parameters of QoTS. Least-satisfied QoTS parameters include staff attitudes, passenger safety, and bus service reliability. Top-rated challenges affecting terminal operations are security concerns, sanitation facility deficiencies and insufficient passenger amenities. MLR analysis indicates a significant influence of terminal facilities on overall service satisfaction (F= 2.899, p= 0.000 <0.05). In conclusion, enhancing both terminal facilities and services is crucial for efficient operations in Lagos State's bus terminals. Recommendations include improving security measures, sanitary infrastructure and staff training to address user concerns and enhance satisfaction.

Geospatial assessment of the efficiency of waste disposal facilities in Lugbe, FCT

Solid waste consists of substances or objects that are disposed of and are mostly found where there are human activities, these substances are accumulations of waste materials generated from domestic, commercial, and industrial operations that are deemed unworthy or rejected and required to be disposed of. The study aims to assess the efficiency of waste disposal facilities in Lugbe FCT, with specific objectives to; evaluate the spatial distribution of waste collection sites (dumpsites) in the area, evaluate the proximity of dumpsites (waste collection sites) to the residential areas, and evaluate the level of appropriate use of waste bins in the study area. Both primary and secondary data were used for this study. The primary data used are the X and Y coordinates of dumpsite locations and questionnaire administration while the secondary data includes; the Google Earth image. Nearest neighbour analysis was performed on the dumpsite's coordinate locations to affirm its spatial distribution pattern in the study area. Buffering analysis was performed on the dumpsite locations with 300m standard to identify the proximity of dumpsites to buildings while the descriptive statistical method was used to analyze the retrieved administered questionnaires to assess the level of the appropriate use of waste bins in the study area. The result of the dispersed spatial distribution of the dumpsites and the result of the proximity analysis performed on dumpsites to the residential area revealed that buildings were found around almost all the dumpsites except the Park Estate dumpsite where no building is found around the dumpsite. At the level of waste bin appropriateness, all the waste bin types were adopted but 72% of waste bin types are appropriate.

Cliff Retreat Rates Associated with a Low-Level Radioactive Waste Disposal Facility in Los Alamos, New Mexico, USA

We present an analysis and interpretation of potential cliff stability at a low-level waste disposal facility at Los Alamos National Laboratory, New Mexico, using cliff morphologic and fracture characteristics coupled with carbon-14 surface exposure dating. Our study is important as it directly bears on the licensing criteria for low-level radioactive waste sites. We find that future characteristic cliff failures will likely not breach disposal pits and shafts over the 1000-year minimum regulatory period. Further, we find, using a multivariate regression model, that slope angle and cliff face aspect are sub-equal in importance to predict regions of high risk of failure when combined with surface exposure ages and assuming that old exposure ages are most indicative of stability (instability) and therefore can aid decision making in final design implementation.

Ambient Radiological Condition around an Operating Uranium Mill Tailings Disposal Facility at Turamdih, India

Large quantity of the feed forms part of the solid waste (tailings) slurry in the low grade uranium ore processing plant at Turamdih in Singhbhum region of Jharkhand, India. Coarser size fraction of this waste is used for backfilling of the underground uranium mines and fine fraction is discharged into an engineered impoundment system or tailings pond. Since inception of the discharges, field expeditions have been performed as part of the comprehensive radiological monitoring program for the facility. The monitoring program broadly consists of ambient gamma dose rate, atmospheric 222Rn and long lived alpha activity measurement around the facility and the estimation of radionuclide in diverse environmental matrices collected from the adjoining sites. Findings reflect that the radiological conditions are comparable to the pre-existing background level adjoining the tailings pond impoundment. Further, measurements for more than a decade confirm that the atmospheric radon concentration profile just a few meters beyond the embankment is indistinguishable from the background.

Sustainable location-routing problem for medical waste management using electric vehicles

The sustainable management of medical waste is essential for environmental protection and public health safety, contributing to urban development and societal well-being. This study focuses on the medical waste Location-Routing Problem with Electric Vehicles (EVs), aiming to mitigate infection risk while providing cost-effective and energy-efficient logistics solutions. It encompasses diverse elements such as disposal location selection, vehicle scheduling, recharge strategies, time windows, working duration, and load-dependent energy consumption. To tackle this complex problem, we introduce an Evolutionary Decomposition-based Adapted Large Neighborhood Search algorithm (E-ALNS/D), which surpasses existing methods such as MOEA/D-HGS, MOEA/D-LNS, MPGA, and NSGAII-LNS across various urban settings. Empirical analysis and a case study reveal opportunities for enhancing medical waste management with EVs. Key findings show that optimizing service times, adopting fast-charging infrastructure, and strategically placing temporary disposal facilities in response to unforeseen demand spikes significantly reduce energy consumption, lower infection risk, and cut charging cost. Furthermore, selecting peripheral over central disposal locations better minimizes infection risks. This research offers valuable insights for decision-makers in EV-based medical waste management, emphasizing the need to balance public health, environmental sustainability, and economic efficiency. Our methodology paves the way for future research in sustainable medical waste management with EVs.

Comparison and Selection of Wet Waste Disposal Modes for Villages in Agriculture-Related Towns Taking Shanghai, China, as an Example

Under the increasingly stringent regulatory constraints, wet waste disposal in agriculture-related towns has become a significant issue. Based on fieldwork in three agriculture-related towns and nine villages located in Shanghai, this paper analyzes the economics and greenhouse gas emissions of three wet waste disposal methods, including centralized disposal, on-site disposal by biogas digesters, and on-site disposal by small-scale biochemical processors, and compares these alternatives by combining various factors, aiming to help decision makers in selecting the optimal alternative. The net present value approach was employed to evaluate the economic aspects of the three disposal methods. The greenhouse gas emissions were calculated using life cycle assessment, life cycle inventory, and the IPCC guidelines. The fuzzy analytic hierarchy process method was employed for a multi-criteria decision-making analysis based on five factors, including economics, greenhouse gas emission control, stability, compliance with environmental regulations, and location feasibility. The results revealed that although centralized disposal is not as good as on-site disposal by biogas digesters in terms of economics and greenhouse gas emissions, centralized disposal is still the optimal alternative according to the results of multi-criteria decision making. The tightening of regulatory constraints will internalize the negative externalities of on-site wet waste disposal. Thus, centralized disposal is the method of wet waste disposal that is most consistent with the regulatory constraints and most sustainable. It is worth emphasizing that policymakers should fully assess the impact of tightening regulations on the selection of wet waste disposal methods, establish a homogenous waste disposal system covering both urban and rural areas, and enhance the management of existing on-site disposal facilities.

Review of Municipal Organic Waste Management in Uttar Pradesh State, India

Organic waste is the main fraction of municipal solid waste in most developing countries. Despite various efforts, municipalities often fail to properly handle generated waste due to poor source segregation, inefficient collection system, insufficient financial resources, and a lack of proper treatment and disposal facilities. In India, organic waste mainly ends up in open dumpsites. The Government of India launched the Swachh Bharat Mission and enacted legislation to improve solid waste management. This notwithstanding, the most populous state of the country, Uttar Pradesh (UP), faces serious challenges in terms of achieving the national environmental policy goals. This study attempts to assess organic management practices in UP by analyzing the existing situation. The study reviewed the legal and financial frameworks governing the waste sector, the responsibility of stakeholders, waste segregation and collection mechanisms in place, and treatment and disposal methods. The identified gaps were analyzed to provide recommendations for the local conditions. The study recommends the control of incoming materials in centralized facilities compost facilities to enhance compost quality and enhance the management of organic waste via source segregation, animal feeding, and treatment in a decentralized manner.

Role of KKN Students in the Development of Sustainable Tourism Villages

Desa Lenek Ramban Biak has transformed into an ecotourism village due to its various tourism potentials, including natural, cultural, and religious attractions. However, both the government and local communities lack awareness of the importance of managing village tourism. Through the Community Service Program (Kuliah Kerja Nyata) conducted by PMD UNRAM, efforts have been made to enhance cleanliness and attract more visitors. Activities include creating photo spots, producing promotional videos, and establishing waste disposal facilities through collective clean-up efforts. The implementation methods involve crafting waste bins from recycled bamboo, conducting clean-up drives at tourist spots, producing promotional videos, and creating photo spots using wood and bamboo. The addition of photo spots aims to make the tourist destination more appealing. The use of bamboo waste bins is intended to raise awareness among the community about waste management and promote a cleaner and healthier environment. Additionally, leveraging technological advancements for promotional video production facilitates wider outreach through social media platforms, thereby increasing awareness among the public. Social media serves as a convenient channel for disseminating information about the tourist destination.

Environmental Analysis of Basic Sanitation Quality of Residential Houses in Cokro Spring Stream Central Java, Indonesia

Abstract Fulfillment of basic sanitation includes clean water, availability of latrines, wastewater disposal facilities, and waste management facilities. Cokro Klaten Spring along its flow has many activities including washing clothes and agricultural activities by the surrounding community. The purpose of this study was to determine the quality of basic sanitation owned by the community using Cokro spring water. This research method is descriptive to find out in detail the conditions that exist at the research location by taking data through questionnaires on respondents as many as 298 households who at the time of the study were carrying out activities using the flow of Cokro Klaten Spring. The results of research on basic sanitation of residential houses along the flow of Cokro Klaten springs are known that all houses (100%) have access to clean water both from wells and PAM which can be used to meet daily clean water needs. However, for the availability of latrines, there are still 9 (3%) houses that do not have latrines and still as many as 20% of houses that have latrines do not meet the requirements for healthy latrines in accordance with the provisions of the Minister of Health No. 39 of 2016. In terms of the availability of waste disposal facilities, as many as 56 (18.8%) do not have waste disposal facilities because they directly throw garbage into the river and from 298 houses there are still 23 houses (7.7%) that do not have wastewater disposal channels, they directly drain domestic wastewater to the back of their yards. The conclusion of this study is that the sanitation of residential houses in the Cokro Klaten spring stream has fulfilled the fulfillment of clean water, but the availability of latrines, waste management facilities and wastewater disposal has not met the basic sanitation requirements. Improvement of basic sanitation is needed to improve the quality of sanitation, especially in the provision of waste disposal facilities so that the community meets the quality of basic sanitation in accordance with the Minister of Health of the Republic of Indonesia Number 829 / Menkes / SK / VII / 1999.

Actual problems of modeling greenhouse gas emissions from municipal solid waste landfills (Review)

Because Russia is one of the world’'s largest emitters of greenhouse gases. The tasks of mitigating the effects of climate change, which are based on ongoing measures to reduce greenhouse gas emissions, are becoming increasingly urgent. Waste, including municipal solid waste (MSW), has long become a problem that poses a threat to the environmental safety of the Russian Federation. Analysis of statistical data shows that the volume of MSW waste is growing from year to year and largely depends on the scale of cities and population. Cities account for more than 70 % of greenhouse gas emissions, and they are the main contributor to the climate crisis. MSW landfills are the third largest anthropogenic source of atmospheric methane. Therefore, it is important to study the formation of methane in the conditions of landfill and its dependence on various factors. This article is devoted to a review and comparative analysis of the functional capabilities of the most well-known calculation methods used to model greenhouse gas emissions from waste disposal facilities. A comparative analysis of such techniques made it possible to determine their advantages and disadvantages, as well as the possibility of mutual substitution of parameters. The parameters of the methods are interchangeable and can be specified for each specific MSW landfill. The accuracy of the calculated prediction depends on the completeness of accounting for all factors affecting the process (climatic conditions, morphological composition of waste, type of landfill, the presence of fires, etc.). As a result of the study, it was found that in order to develop a scientifically sound methodology for estimating greenhouse gas emissions from waste disposal facilities, additional comprehensive studies are necessary. In particular, supplementing the list of wastes considered in the IPCC methodology with other types of waste in accordance with the Federal Waste Classification Catalog, determining the required parameters for these types of waste, as well as clarifying the parameters of the model for the possibility of using it in calculating emissions from a specific waste disposal facility.
