Anaerobic Biodegradability and Biomethanation Potential of Fruit-Vegetable Wastes at Sindh, Pakistan

The urban environment of every city of Pakistan has been degraded because of open dumping and burning of organic wastes along with other wastes. The focus of this study was to evaluate the fruit and vegetable wastes for methane generation through biomethanation process. After collection, various parameters such as alkalinity, volatile fatty acids, pH, lignin content, moisture content, total solids, volatile solids, fixed carbon, and elements (C, H, N, O, S) of waste samples were determined by using standard methodology. Anaerobic biodegradability of fruit and vegetable wastes was observed from 54 to 77% and from 59 to 87% along with their methane generation potential in the range of 258-367 NmL /gmVS and 274-407 NmL/gmVS, respectively. Further, the effect of feedstock to inoculum ratio was studied. The result of that showed that lower methane potential at a higher ratio and vice versa was observed. It was concluded that at a lower feedstock to inoculum ratio, fruit as well as vegetable wastes become more feasible for the biomethanation process. The study recommends that the conversion of fruit and vegetable wastes into methane gas by anaerobic digestion plays a significant role to save urban environment of the country.

Assessment of Fe, Ni, Zn, Cu, Cr, and Cd Migration in Soil Profiles Affected by Open Dump Leachate in Tanjero area

The properties of an open dump area are important to the application of the elements to the soils and their migrations through soil depth; therefore this study was investigated to evaluate the migration of elements in an open dump area. Soil samples were taken from three soil profiles, one of them was at an open dump site, and the second and third profiles were taken at different distances from the open dump site. In total eighteen soil sample were collected. Some soil physical and chemical properties were determined for each horizon. Total concentrations of Fe, Ni, Zn, Cu, Cr, and Cd were determined in each soil sample. The results indicated that the Fe had the highest value and the Cd had the lowest values in all soil samples. The orders of profiles for the total heavy (Ni, Cd, and Cr) metals were as follows: Profile1 > profile3 > profile 2. The order of profiles for the total heavy (Zn and Cu) metals was as follows: Profile 1 > profile 2 > profile 3. The mean value of total Ni ranged between 9.17 and 11.13, Cd between 0.29 and 0.37, Cr between 2.67 and 3.36, Zn between 6.90 and 17.23, and Cu between 4.90 and 12.52. The highest amount of total Ni, Cd, Cr, Zn, and Cu were observed in open dump area (profile 1) with the mean value (11.13, 0.37, 3.36, 17.23, and 12.52) respectively, compared to the profile 2 and 3. In general, the heavy metals did not show a specific pattern of distribution with depth in the three soil profiles, because there are many factors affecting migration of heavy metals in soil depth. In both profile 2 and 3, some of the heavy metals migrated in soil depth.

Vermi degradation of different dietary supplements mediated on the reproduction and metabolic profile of earthworm Eudrilus eugeniae

Earthworm growth and reproduction is influenced by the environmental variables such as temperature, moisture, substrate and nutrient content in vermibed materials. By using different kind of dietary supplements with the conventional vermibed materials raise the development and reproductive potential of the earthworm Eudrilus eugeniae. The current study evaluated on particular periods such as 10th, 45th, and 90th day in vermibins with dietary supplements in the ratio of 1:1 the 50% Ficus religiosa leaf litters + 50% cow dung (T1); 50% Lawsonia inermis leaf litters + 50% cow dung (T2); 50% sugarcane bagasse + 50% cow dung (T3) was used and 100% cow dung serves as control (C). Among these vermibins, T3 vermibin treated earthworms had the highest growth, reproduction, highest sperm count in the seminal vesicle, hatching success, and also increased the metabolic profile of earthworms such as protein, carbohydrate, and lipids in tissues and seminal vesicle. Compared to the other nutritional supplements, the present study result revealed that cow dung and sugarcane bagasse together have a significant positive impact on earthworm growth and reproduction. This study emphasized on the enhancement of the reproductive capacity of the earthworm Eudrilus eugeniae by incorporating different dietary supplements with the traditional vermicomposting methods. This also helps to analyse the influence of the metabolic profile in the growth and development and even on the reproductive index of the earthworm which is been observed on three different period: 10th, 45th and 90th day of experimentation. In the current research multi output can be ensured by integrating with production of crops, vermicompost, earthworm growth and waste management. This present study also represents that the open dumping of such a huge quantity of dung materials and plant and animal wastes will create environmental pollution and benefits for soil fertility improvement.

Pot experimental trial for assessing the role of different composts on decontamination and reclamation of a polluted soil from an illegal dump site in Southern Italy using Brassica juncea and Sorghum bicolor

A pot experiment was carried out to evaluate the remediation potential of Brassica juncea and Sorghum bicolor in the decontamination of soil polluted with heavy metals such as copper, lead, tin, and zinc along with polychlorinated biphenyls, polycyclic aromatic hydrocarbons, and heavy hydrocarbons. Two composts obtained from different composting processes were tested as biostimulating agents. At the end of the trial, the effect of plant/compost combinations on soil microbial composition, contaminant removal, biochemical indicators, and plant biomass production was determined. The results highlighted that compost addition improved plant biomass despite slowing down plants’ removal of organic and inorganic contaminants. In addition, compost partially enhanced the soil biochemical indicators and modified the relative abundance of the rhizosphere microorganisms. Sorghum showed better mitigation performance than Brassica due to its higher growth. The soil fertility level, the choice of plant species, and microbial richness were found fundamental to perform soil remediation. In contrast, compost was relevant for a higher crop biomass yield.Graphical abstract

Spatial distribution and characteristics of plastic pollution in the salt marshes of Bahía Blanca Estuary, Argentina

This study delves into the magnitude and attributes of plastic pollution in the salt marshes of the Bahía Blanca Estuary, Argentina, with a specific focus on its spatial distribution. The investigation included the evaluation of microplastics (1–5 mm), mesoplastics (5–25 mm) and macroplastics (25–100 mm), discovering elevated levels along the high salt marsh strandline compared to low salt marsh and mudflat areas. Notably, the abundance of plastic reached staggering levels, reaching up to 20,060 items/m2 in the vicinity of an illegal dumpsite. Microplastics, particularly in the 2–4 mm range, were dominant, and the main plastic components were high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), and polystyrene (PS). Plastic films emerged as the predominant plastic type, while the presence of pellets hinted at potential sources such as illegal dumping and port-related activities.This contamination could be largely attributed to inappropriate waste management practices and urban runoff, which pose a substantial ecological threat to these ecosystems. Urgent remedial action is essential to protect these marshes, underscoring the critical need for comprehensive wetland management and educational initiatives to ensure their long-term sustainability.

Municipal solid waste management: Identification and analysis of technology selection criteria using Fuzzy Delphi and Fuzzy DEMATEL technique

Municipal solid waste management (MSWM) poses a considerable challenge to developing countries like Bangladesh because of the rising waste generation rates and lack of effective management practices such as illegal open dumping and informal waste collection. One of the crucial factors in the successful management of MSW is to select the appropriate technology which is a complex multi-criteria and laborious process. Despite the global emphasis on the importance of MSWM in the literature, there is a lack of studies conducted in developing countries that effectively identify and analyze the critical performance criteria for appropriate technology selection. This research aims to address this shortcoming by identifying, and prioritizing the selection criteria and finally investigating the inter-relationship between them and the degree to which they affect or are affected by one another. First, a thorough literature review and expert consultation were employed to determine a set of 21 key criteria using the Fuzzy Delphi method (FDM). Later, taking into account the imprecise and subjective nature of the DEMATEL method on human judgements, the Fuzzy DEMATEL technique was employed to investigate the cause-effect relationships among the identified criteria. The findings of the study demonstrated that 14 criteria were categorized as causal elements that have the most significant influence on the MSWM technology selection process and 7 criteria were categorized as effect. The selection of MSWM technology demands greater consideration of the top three ranked criteria, namely T4- Access to Technology (AT), T8- Feasibility (F), and the Ec6-Infrastructure requirements (IR). By identifying the pertinent criteria, structures and interrelationships, the outcome of the study can facilitate a better understanding of causal relationships among the criteria that require specific consideration from the decision-makers and allow them to select appropriate MSW management technology.

Recycling of construction waste as an innovative direction of the program of post‐war reconstruction of destroyed cities

AbstractThere are officially more than 5.5 thousand dumps in Ukraine, landfills with a total area of more than 9,000 hectares, and there are more than 2000 illegal dumps. The issue of waste disposal (garbage) has always been very acute, not only during the war, a significant part of this waste is construction waste. During the hostilities, many Ukrainian cities and settlements suffered various types of destruction, and some suffered almost the greatest destruction of various objects of urban infrastructure. All this contributed to the emergence of a large amount of demolition waste. The article analyzes the current state of management of demolition waste in Ukraine. The goals and objectives of recycling construction waste in the conditions of post‐war reconstruction of destroyed urban areas are formulated. The results of theoretical studies of methods of utilization of demolition waste by their reuse in construction are given. The preferred types of construction waste in case of destruction of buildings include clogged soil, asphalt, stone materials, brick, concrete and reinforced concrete, wood, ceramic tiles, etc. Each of these types of demolition waste needs a separate recycling. The article gives the classification and structure of demolition waste and defines, what operations to handle it are required. The requirements for the arrangement of temporary storage of construction waste are formulated. Prospects for the development of recycling of demolition waste in Ukraine are considered. The ways of reuse in construction of demolition waste components are proposed. Recommendations of measures of step‐by‐step management of construction waste in Ukraine were provided.

Revealing subsurface structure at the former municipal solid waste disposal site Leuwi Gajah of Cimahi Town by using geophysical data: a preliminary result

Municipal solid waste disposal site Leuwi Gajah, situated in Cimahi, is near Bandung City. It was a vast open dumping site closed in 2006 due to a harmful geological hazard in 2005, causing hundreds of victims’ deaths. After 16 years of the tragedy, Bandung local government planned for the former municipal solid waste to become a food field with high technology that benefits the community around the area. We applied the Electromagnetic Induction (EMI) technique to image the study area’s subsurface structure as a non-invasive geophysical method. We collected apparent electrical conductivity (ECa) and apparent susceptibility data from the study site in a gridded pattern to map their distribution using EM-38 MK-2 technology. We chose three sites to map those parameter values: site 1, site 2, and site 3. Site 1 is cassava cultivation land by the community. Site 2 is the boundary between former waste and non-waste land, and site 3 is the same land as site 1 but has a steeper slope (20°). The selection of sites 1 and 3 compares land at higher and lower elevations affected by the former landfill landslide. Site 2 shows the difference in characteristics between waste and non-waste land.Our research in the study area delivers good results. First, we can identify the boundaries of waste and non-waste material, as shown in the low susceptibility value at site 2. This identification is probably related to the thermo-remanent magnetization that results from burning waste. On the other hand, water content influences the distribution of ECa values. Moreover, topography has effects that cause water accumulation in certain areas at sites 1 and 3. These findings recommend using other geophysical methods to detect the boundary between the waste deposit body and underlying bedrock and to characterize the waste body.

Two-Dimensional Modeling of Leachate Distribution in Batu Layang Landfill on Peat Soil using Geoelectric Method

The open dumping system implemented by the Batu Layang landfill can produce leachate, contaminating groundwater around the landfill. Groundwater contaminated with leachate, if used by the community, can cause health problems. Therefore, management efforts were needed, such as subsurface leachate modeling. This study aims to model the distribution of subsurface leachate in 2 dimensions. The modeling of leachate distribution below the soil surface used the Wenner configuration geoelectric method. The number of geoelectric measurement paths was two paths. The length of each track was 195 m, with a distance of 5 m between the electrodes. Data obtained from resistivity values were analyzed using the Res2Dinv application. The calculation of leachate discharge used the water balance method. Based on the inversion results using the Res2Dinv software, the resistivity value of leachate-contaminated soil in line 1 was 1.19-9.43 Ωm, and track 2 was 0.5-10.2 Ωm. The leachate resistivity value was <10 Ωm because the leachate contains inorganic minerals (metals), so the resistivity value was low. Land contaminated with leachate was estimated to be spread as far as 195 m. The most profound leachate depth was estimated at 39.4 m. Batu Layang Landfill leachate discharge in Zone E averages 4 m3/day.

Detection of Construction and Demolition Illegal Waste Using Photointerpretation of DEM Models of LiDAR Data

Illegal waste is a global problem with negative impacts on human health and the environment. This article focuses on detection using remote sensing of sites of demolition and construction waste. We hypothesise that construction and demolition waste represent a human modification of terrain and, as a result, will be sensible to detection using visualisation models of terrain, specifically DEM (digital elevation model). To this effect, we start with a DEM of 0.25 m per pixel developed using data from the second iteration of the PNOA LiDAR project by the Spanish National Geographic Institute (IGN). We evaluate seven modelling tools of the Relief Visualisation Toolbox (RVT) for the visual detection of waste. The study area includes the city of Mérida (Extremadura, Spain). Our fieldwork identified 494 points of illegal waste in this area. These points were classified according to five categories in relation to land use, and we established a total of 14 areas with a surface area of 450 m by 450 m. Our results suggest that three of the seven models employed allow us to differentiate with clarity what is anthropic from the natural terrain and, in some scenarios, the location of construction and demolition waste. The LD model was the one with the best results, allowing an increase in the number of locations of illegal dumping of CDW in the study area.

The Processing of Household Waste by Residents of Griya Serpong Housing Complex, Serpong Sub-District, South Tangerang, Indonesia, in Compliance With Law Number 18 of 2008 and Law Number 32 of 2018

The Waste Management Law Number 18 of 2008 mandates waste management at various levels, including producers, communities, industrial areas, traditional markets, and malls. Local government administrations in regencies and cities need to create or revise regional regulations (Perda) and design a communal-based waste management masterplan. Until now, waste management has largely been centralized, with an open dumping system at the final disposal site, which ended in 2013. There are three forms of urban waste management: centralization, decentralization, and centralization-decentralization. An ideal waste management pattern is neither purely centralized nor decentralized, but rather a combination of both. Organic Waste Management Facilities (OWMF) are established at the source of dominant waste generation (initial stage), with a recycling system similar to City Waste Management Facilities (CWMF) to support and assist in marketing the products of the OWMF established by Joint Business Groups (KUB) formed by the community, known as the "self-sustaining concept." Addressing the waste problem requires an examination of the current waste management practices to identify areas where improvements and enhancements can be made, so that only waste that truly cannot be recycled ends up in the final disposal site, such as hazardous waste (B3) that is incinerated directly. This research aims to provide a solution to the waste disposal issue, which is largely centralized in Indonesia.

Polychlorinated biphenyls in bovine milk from a typical informal electronic waste recycling and related source regions in southern India before and after the COVID-19 pandemic outbreak

For more than a decade, Chennai city in southern India has been evidenced with informal electronic waste (e-waste) recycling and open burning practices as the potential sources for polychlorinated biphenyls (PCBs). PCBs can bioaccumulate in livestock particularly cows grazing on the contaminated soil. The outbreak of the COVID-19 pandemic led to additional challenges associated with waste management practices. Hence this study aims to elucidate twenty-five PCB congeners in bovine milk from the previously reported PCB source regions in Chennai and the suburbs before and after about three years of the pandemic outbreak along electronic waste recycling (EWR), open burning dumps (OBD), and residential (RES) transects. The geomean concentration of Ʃ25PCBs in ng/g lipid weight (lw) followed a decreasing trend of EWR (13 ng/g lw) > OBD (8 ng/g lw) > RES (4 ng/g lw). Over 80 % of PCBs stemmed from EWR and OBD transects before and after the pandemic. However, a significant surge in the level of PCB-52 was observed in the OBD transect after the pandemic outbreak. Most toxic PCB congeners, PCB-126 and -169 were significant contributors to TEQs in EWR and OBD transects and can be reasoned with the burning of waste materials and mixed plastics in these transects. The highest average daily dose (ADD) exposure risk was for children from EWR and was significantly higher (p < 0.05) than other transects. Mean ADD-induced TEQ (6.6 pg TEQ/kg-bw/day) from the cows grazing around Kodungaiyur dumpsite slightly exceeded the EU guideline of 5.5 pg TEQ/kg-bw/day after the outbreak of the pandemic due to PCB-126. However, none of the samples exceeded the US FDA (1.5μg/g milk fat) recommendation limits for PCBs in milk fat. Prolonged exposure to such persistent organic pollutants interlinked with the burning of mixed waste in the open dumps can be a public health concern.

An Evaluation of the Impact of Illegal Dumping of Solid Waste on Public Health in Nigeria: A Case Study of Lagos State.

The illegal dumping of solid waste is a prevalent issue in Nigeria, affecting all states. Lagos State, in particular, faces waste disposal problems that stem from urbanization, negative public perception towards waste management, insufficient waste disposal education, poor waste disposal practices, and the disposal of waste at illegal and unauthorized sites. This situation is further exacerbated by inadequate municipal solid waste (MSW) collection rates, making it challenging to combat illegal dumping effectively. To align with Sustainable Development Goal (SDG) 11 of Sustainable Cities, which seeks to minimize negative environmental effects associated with managing MSW by 2030, this study aims to assess the environmental and health impact of illegal dumping of solid waste in Lagos State. The objectives of this study include assessing people's attitudes towards illegal dumping, evaluating the extent of environmental degradation resulting from illegal solid waste dumping in Lagos, and assessing the health risks associated with exposure to illegally dumped solid waste in Lagos State, as well as determining if illegal dumping contributes to the diseases prevalent in Lagos State. This study will use a quantitative approach to collect data from study participants on demographics, educational background, waste management, and environmental and health issues using computer-assisted self-administered questionnaires (Google Forms). This study will also use observations and photographs of illegally dumped waste in communities and major illegal dumpsites in the study area to provide valuable information to complement the questionnaire responses. By combining both approaches, the study will be able to capture both numerical data and people's behaviors and attitudes associated with illegal dumping. This study will use a mixed sampling method consisting of cluster sampling and convenience sampling, focusing on communities impacted by illegal dumping in Lagos State. The sample size for this study will be 100. The questionnaire for this study will be administered via a Google Forms link that will be shared through various online platforms, enabling participants to access and complete the questionnaire from any location with internet access. To ensure representative participation, as part of the informed consent form on the initial page of the online questionnaire, a screening question that requires participants to indicate if they live or work in the study areas or have been exposed to the impact of illegal dumping will be included. Only those who meet these criteria will be able to proceed with the study. The primary data obtained will be carefully analyzed using the Statistical Package for the Social Sciences (SPSS) version 28. The study's results will highlight the importance of the linkage between illegal dumping, environmental degradation, and diseases prevalent in Lagos State, which could inform policymakers and relevant departments in developing effective strategies to improve public health.

Illegal dumping from ships is responsible for most drink bottle litter even far from shipping lanes

Recent studies using bottles as tracers have shown that illegal dumping from ships is responsible for the rapid increase in drink bottles washing up on oceanic islands and at remote continental beaches away from local litter inputs. However, these studies have been in areas with moderate to high levels of shipping activity. I examined bottles stranded on the Pitcairn Islands in the central South Pacific, which are far from major shipping routes. Drink bottles from Asia dominated, with most coming from China. The top four brands (three Chinese and one multinational) were the same as at Tristan da Cunha in the central South Atlantic Ocean, which lies on the shipping route between South America and Asia. Bottle ages also were similar at Pitcairn and Tristan, indicating that vessels are the main source of bottles at both islands. Stricter controls are needed to reduce illegal dumping of plastics at sea.

Occurrence, persistence, and ecological risk of bisphenol A in surface water receiving raw leachate from a municipal solid waste open dump in Kerawalapitiya, Sri Lanka

AbstractBisphenol A (BPA) is an anthropogenic chemical compound utilized to manufacture a wide range of consumer products, such as polycarbonate, polyvinyl chloride (PVC), food packages, and thermal papers. Because of its extensive worldwide use, BPA is pervasive in the environment, negatively affecting aquatic life. Therefore, we studied the occurrence, persistence, and ecological risk of BPA in surface water receiving raw leachate from a municipal solid waste (MSW) open dump in Kerawalapitiya, Sri Lanka. Our findings corroborate that the BPA average concentrations in the canal network were 0.4–42.6 µg/L during the wet season and 0.2–4.9 µg/L during the dry season. The levels of BPA at 11 locations (out of 16) during both seasons differed significantly from the upstream sample, where there was no impact from the dump site (p &lt; 0.05), indicating the ubiquitous occurrence and persistence of BPA in the canal network. BPA levels in the waterbodies are greater in the wet period than in the dry period because of the continuous ingress of run‐off‐driven leachate to the canal network. Our study infers that pH and salinity correlate positively with BPA, while temperature, DO, and TSS are negatively correlated with BPA. BPA levels in five locations during the wet season and one during the dry season surpassed the tolerable level of BPA stipulated by the Canadian Federal Environmental Quality Guidelines to safeguard aquatic life, which is 3.5 µg/L. The findings of the acute ecological risk assessment articulate that during the wet season, Mozambique tilapia (Oreochromis mossambicus) and orange chromide (Etroplus maculatus) constitute a high acute risk, while they pose a medium acute risk during the dry season. Our study suggests that the relevant authorities must prevent the ingress of runoff rich with BPA onto the canal network to protect aquatic life.

Metal levels in waste pickers in Brasilia, Brazil: hair and nail as exposure matrices

ABSTRACT The aim of this cross-sectional study was to compare workplace conditions and metal exposures in 431 waste pickers who worked nearby at the Estrutural Dump in Brasilia utilizing hair (n = 310) and nail (n = 355) as matrices of exposure. Waste pickers were grouped according to their workplace (open waste dump: G1 and sorting plants: G2). Hair and nail samples were collected and analyzed using ICP-MS. The work duration in the facilities was significantly different between the groups with averages of 16.46 (8.48) yrs and 9.26 (6.28) yrs for hair donors in G1 and G2, and 15.92 (7.72) yrs and 8.55 (5.77) yrs for toenail donors in G1 and G2, respectively. The arithmetic means (μg/g) of cadmium, copper, lead, and manganese in hair were significantly higher in G2 (0.076 ± 0.133; 19.61 ± 18.16; 2.27 ± .56 and 3.87 ± 5.59, respectively) compared to G1 (0.069 ± 0.235; 15.72 ± 15.18; 1.72 ± 4.04 and 3.65 ± 5.5, respectively). Concentrations of arsenic, barium, cadmium, copper, cobalt, lead, manganese, and molybdenum in nail were significantly higher in G2 (0.57 ± 0.39; 22.74 ± 42.06; 0.1 ± 0.08; 22.7 ± 51.60; 0.48 ± 0.45; 4.69 ± 9.43; 19.07 ± 20.75; 1.80 ± 1.76, respectively) compared to G1 (0.40 ± 0.28; 15.32 ± 22.31; 0.08 ± 0.11; 11.91 ± 16.25; 0.37 ± 0.37; 3.94 ± 15.04; 13.01 ± 19.08; 1.16 ± 1.80, respective. Our findings suggest that the studied population was exposed to toxic metals and indicates the need for chemical exposure prevention policies to monitor chemical risk exposures in waste pickers.

Comparison Of Sewage And Solid Waste Disposal Methods Among Households In Urban And Rural Local Government Areas Of Anambra State

Improper sewage and solid waste disposal lead to environmental pollution and increased risk of communicable diseases. This study compared the sanitation and solid waste disposal facilities utilized in selected rural and urban local government areas of Anambra State, Nigeria. This cross-sectional study was conducted among 1310 households and data was collected from household heads or a designated adult representative using of quantitative (questionnaire) and qualitative (KII) data collection methods. The independent variables in this study are the sociodemographic variables and the geographical location of the respondents while the dependent variables are the toilet facilities and solid waste disposal methods. Data from the questionnaire was analyzed using the SPSS version 23 and the hypotheses were tested with the inferential statistics of Chi square at 0.05 level of significance. Most respondents lie between the age group of 31-50 years. Most of the respondents in both the urban (84.4%) and rural(65.0%) areas had secondary education and above but a higher proportion in the urban compared to rural have tertiary education(41.9% versus 22.1%). The difference in educational status was statistically significant (p = 0.0001). There were more business men (46.6%) and civil servants (38.8%) in the urban area than the rural area. Most rural respondents were farmers(41.5%). Many urban household use toilet with sewer connection 152(11.7%) while pit latrine with slab is the most commonly used toilet facility 242 (18.6%). Burning was more commonly used by the rural households (n = 266, 20.5%). Open dumping of refuse and disposal into gullies and water ways were commonly done by the urban households. The gaps that exist between rural and urban areas of Anambra state may present serious health risk and environmental degradation .This issues can be addressed through health education, building more sanitary infrastructure to include the rural areas and enforcing sanitation laws.&#x0D; &#x0D;

Towards integrated, and sustainable municipal solid waste management system in Shashemane city administration, Ethiopia

Solid waste generation is attested to be unavoidable product of human activities. Sustainable management of such waste is a pressing challenge faced in many developing countries today. The study was motivated by the fast growing population and the inefficient waste management system threatening the public health and the image of Shashemene city in Ethiopia. The objectives of the study were: to explore the existing household solid waste management practices, to examine the current governance system of municipal solid waste management, to investigate the contemporary challenges and opportunities of municipal solid waste management, and forward integrated and sustainable municipal solid waste management system for Shashemene city. Data were collected from sampled households, key informants, focus groups, and the city's environment. Data were analyzed by employing quantitative and qualitative methods. 94.8 % of the respondents opined that the solid waste generated in their city is organic in nature (Ash, and sweeps; leftover food, and vegetable peels; paper, and cardboards; green leaves, and grass; and cattle dung). 96.7 % of respondent households opined that they have temporary waste storage in their yards and trash bags were asserted to be widely used (87.6 %) in handling the trash in the courtyard. The waste sorting and recovering practices among the residents is very low and is certainly the major cause for inefficient and unsustainable management system of municipal solid waste in Shashemene city. Generally, a grand mean of 2.23 confirmed the absence of good governance in municipal solid waste management system in Shashemene city. Moreover, the significant proportion of responses ( ≥ 50 %) for each of the nine principles of good governance as either poor or very poor asserted governance failure of the municipal solid waste management system in Shashemene city. The results of the study confirmed that low public awareness on waste management; inadequate collection capacity; poor integration and coordination of stakeholders; environmentally unsound dump site; and illegal dumping by key stakeholders are the major challenges underpinning the unsustainable municipal solid waste management in the city. It is recommended that Shashemene city must adopt integrated sustainable municipal solid waste management system to substantially enhance the waste management service in the city leading to ultimate advancement of public health and environmental quality.

Traversing the Waste Spectrum: Unveiling Pakistan's MSW Landscape and Solutions

Municipal solid waste (MSW) management must be sustainable in order to meet the Sustainable Development Goals (SDGs) and address health, environmental, and disposal challenges caused by the vast amounts of trash generated. MSW management going wrong puts locals in danger. In Pakistan, the production of municipal solid trash is rising daily. Urban settlers and other organizations gather a lot of waste in various forms, usually defiling and making our surroundings uninviting. Due to the indiscriminate dumping of various wastes, the soil quality in the metropolitan area has decreased as a result of solid and liquefied waste disposal. Significant environmental concerns regarding soil and water pollution arise from transferring contaminated garbage and mixed fluid outside of waste disposal borders. The impacts of municipal garbage disposal on soil and water quality at open waste dumping sites were the main focus of this review. Using a soil and water quality index, in many regions of the world especially in regions where waste management practices are insufficient, the contamination of soil and water owing to incorrect municipal solid waste disposal is a serious environmental hazard. Open dumping, unregulated landfilling, and illegal dumping are examples of improper waste disposal practices that can result in pollution that affects the quality of the soil and water. They must also seek to identify sustainable waste management solutions. The effect of these emitted gaseous emissions has, however, been thoroughly researched. To safeguard the environment and public health, quick action must be made to control trace element pollution.
