Household Waste Management Practices among the People of Shamli District: An Assessment

Solid waste management has turn into a primary environmental issue in India. Improper disposal and waste management have a grim effect on the surroundings and human health condition (physically & mentally). This study aims to assess solid waste management among households of Shamli district. Simple random and systematic sampling techniques were used to select 344 respondents for the study. Simple frequency and percentage method was used to analyze the data. Results indicates that public waste collection area was far from households as endorsed by the majority (51.5%) of the respondents. The majority (51.5%) of the households spanned a distance of more than 15 minutes arriving to the dumping spot. In conclusion, the study found that community household waste dumping zone was outlying from households. This indicates that the distance from the resident place to the final waste disposal area covered more than 15 minutes to complete the journey. Based on the major findings of the study, researcher proposes that district assembly needs to provide waste collection trash to every household. It may oblige the residents not to dispose of their household waste randomly.

Mercury in natural gas: delivering accurate reservoir sampling and analysis

Natural gas is a critical part of the world’s energy supply and plays an important role in the transition to lower-carbon energy sources. The industry’s ability to process natural gas safely and efficiently will continue to rely on an accurate understanding of feed gas composition and contaminants, particularly in enabling future developments via existing infrastructure. Mercury is toxic to organisms, highly volatile and produced from hydrocarbon basins globally. Trace mercury concentrations in the hydrocarbon stream can potentially introduce liquid metal embrittlement hazards to industrial equipment, including cryogenic heat exchangers used to refrigerate liquefied natural gas. Inaccurate measurement of mercury levels can lead to adverse impacts measurable across the areas of health, process safety, environment, operations, waste disposal and decommissioning. Worldwide, significant project cost overruns and processing incidents have resulted from the uncertainty of mercury concentrations in hydrocarbon streams. Successful mercury management ideally begins early in a project’s lifecycle with development decisions informed by accurate measurement of mercury concentrations from reservoirs. Historically, this has been problematic, as mercury contamination and scavenging often result in a large range of uncertainty. The results from a multi-company collaborative study to reduce mercury uncertainty with new downhole sampling techniques will be shared in a case study, including production insights from the Julimar Field, west coast of Australia. The recommendations, procedures and operational best practices discussed will be applicable across the industry and beneficial to any party considering the impact of mercury in the development and processing of natural gas resources.

Role of nanohybrid NiO–Fe3O4 in enhancing the adsorptive performance of activated carbon synthesized from Yemeni-Khat leave in removal of Pb (II) and Hg (II) from aquatic systems

Over years, existence of toxic chemical heavy metal in aquatic systems has motivated more research studies toward the preparation of effective stable solid adsorbents for the removal of toxic chemical pollutants. Therefore, in the current research study, activated carbon adsorbent (AC) was synthesized from Yemeni khat (catha edulis) leaves which are considered as waste accumulated on waste disposal areas in Yemen. KOH (2.0 N) was used as a chemical activator to produce the AC material which was subsequently heated at 400 °C. A simple co-precipitation method was used to chemically modify AC with varying weight ratios of NiO–Fe3O4 NPs (5, 15, and 25 wt %). The modified AC was used to remove toxic Pb(II) and Hg(II) ions from aquatic systems. Numerous techniques, which included x-ray diffraction (XRD), Fourier transforms infrared (FTIR), field emission scanning electron microscope (FE-SEM), and N2 adsorption/desorption isotherms, were used to confirm the morphology of AC and 5, 15, and 25 wt% NiO–Fe3O4/AC samples. The study findings demonstrated that, NiO–Fe3O4 nanoparticles improved the adsorption efficiency for toxic Pb(II) and Hg (II) ions. The AC adsorbent attained maximum removal efficiencies of 88.95% and 87.56% for Pb (II) and Hg (II) ions, respectively. In contrast, 15-NF/AC NC sample successfully attained the highest removal efficiencies of 100% for pb(II) and 99.71% for Hg(II). According to the experimental findings, the prepared NF/AC adsorbents were effective and they can be used as inexpensive and stable solid nanoadsorbents in water treatment.

The paper presents the study results of the rock waste disposal area colonization with vegetation at the Kizelovsky coal deposit according to remote sensing data of the Earth and calculations of the vegetation index NDVI for the Perm Territory. It was determined that natural colonization of disturbed lands were taking place. An increase in the average values of vegetation for the studied dumps in the period 1986–2021 was revealed which is primarily due to the cessation of mining in the territory under consideration.

Knowledge and practices of water and sanitation and prevention of water-borne diseases among the residents of Wabgaon village

Background: Globally 1.339 billion U-5s and 79 thousand neonates aged 0-27 days were estimated to be dead due to diarrhoea. India, Nigeria, Afghanistan, Pakistan, and Ethiopia accounts for more than half of the deaths caused by diarrhoea. Our objectives are to understand the knowledge and practices of WASH, preventive and treatment measures of diarrheal diseases, the feeding practices and hygiene among the mothers in the rural village of Wardha district. Methods: This is a mixed method study with study participants including 72 families randomly selected along with the front-line workers. the descriptive analysis was carried out with the help of R software and other online statistical software. Results: 90.6 % had their source of water away from a contaminated place such as open drains, manure pits, solid waste disposal areas etc. Though 96.9% had toilets in their household only 93.8% actually used it. All of them washed their hands with soap after using the restroom. Mixed responses were obtained when people were asked about the line of action in case, they suffer from any of the acute diarrhoeal diseases. 90% of them prefer ORS during such times and the source of availing had mixed responses. Conclusions: An interventional study for the same can be carried out. Regular follow ups might assist in keeping the public free from such communicable discomforts.

A probabilistic approach to the estimation of radioactive contaminant inventories at a nuclear waste disposal site

Routine site inspections are often conducted to gather data on radiation contamination on the surface and below ground near nuclear waste disposal areas. These observations are used to calculate total radiation inventory and its spatial delineation. The statistical kriging approach is often used to spatially interpolate contamination data, and it generates predictions at unsampled sites that are then utilized to calculate the contaminated site's radiation inventory. The kriging output, however, creates a point estimate of the inventory that omits the potential uncertainties from other sources. This paper presents a method for assessing the uncertainty of radiation inventories based on the geostatistical conditional simulation method – a simulation methodology that takes into account the observations made at the sampled sites. The radiation inventories' histograms are generated by conducting many conditional simulations of the projection map using a fitted kriging model. A practical implementation of the suggested approach is shown by evaluating total beta inventories and their spatial delineation using groundwater monitoring data at a nuclear waste disposal site.

Isolation and screening of low-density polyethylene (LDPE) bags degrading bacteria from Addis Ababa municipal solid waste disposal site “Koshe”

PurposeThis study aims to screen bacterial isolates from the Addis Ababa municipal solid waste dumping site (Koshe) for the biodegradation of low-density polyethylene bags and analyzes their efficiency in degrading plastic bags.MethodsIn this study, low-density polyethylene bag-degrading bacteria were isolated from the Koshe municipal solid waste disposal area in Addis Ababa, Ethiopia. Screening of isolates for low-density polyethylene bag biodegradation was carried out using a clear zone method. Additionally, the efficiency of the isolates for low-density polyethylene biodegradation was evaluated using the weight loss method, scanning electron microscopy analysis, and Fourier transform infrared analysis. Finally, molecular identification of potential low-density polyethylene degrader bacterial isolates was done by 16S rDNA sequencing.ResultsIsolates KS35, KS14, and KS119 resulted in significant weight loss of low-density polyethylene film (42.87 ± 1.91%, 37.2 ± 3.06%, and 23.87 ± 0.11% weight loss, respectively). These isolates were selected for further biodegradation study using scanning electron microscopy and Fourier transform infrared analysis. Scanning electron microscopy analysis shows the formation of pores, pits, and distortion of the plastic surface. Fourier transform infrared analysis indicates the appearance of new peaks at the surface of low-density polyethylene films. Phylogenetic analysis of the three potential bacterial isolates was also carried out, and the result indicates that the sequence of isolate KS35 had 99% similarity with sequences of Methylobacterium radiotolerans MN525302. Isolate KS119 had 100% similarity with Methylobacterium fujisawaense KT720189, and the sequence of isolate KS14 had 99% similarity with species of Lysinibacillus fusiformis.ConclusionsWeight loss, scanning electron microscopy analysis, and Fourier transform infrared analysis results show that isolates KS35, KS14, and KS119 have high potential in degrading low-density polyethylene bags.

Using Precision Agriculture (PA) Approach to Select Suitable Final Disposal Sites for Energy Generation

Severe environmental pollution and disease exposure are caused by poor waste management, specifically in urban areas due to urbanization. Additionally, energy shortage has threatened almost all parts of human life in the world. To overcome this problem, a precision agriculture approach using spatial mapping based on social environmental factors and sustainability principles can be used to find the variability of sites with respect to their suitability for waste disposal and energy generation. Therefore, this study aimed to develop a system for selecting suitable areas for municipal waste disposal and energy generation based on several structured criteria as hierarchical weighted factors. The system prototype was developed and tested in a case study conducted in an Indonesian Megapolitan area. The suitability map produced by the system for waste disposal and energy generation had an accuracy of 84.3%. Furthermore, validation was carried out by ground-checking at 102 location points. A future application of the proposed system is to provide spatial data-based analysis to improve regional planning and policy-making for waste disposal and energy generation in certain areas, particularly in Indonesia.

Biomining: A Sustainable Solution for Reclamation of Open Landfills in India

Urban India produced around 62 MT of municipal solid waste (MSW) (450 gcapita-1day-1) in 2015. Approximately 82% of the generated MSW was collected and only 28% of the collected waste was treated and the remaining 72% was openly dumped. Open dumping is the popular MSW disposal practice in India due to budget constraints and lack of technological advancement. Open dumpsites are considered a potential threat to environment and human health since they contaminate land and water resources during migration of leachate and create air pollution in terms of release of landfill gases (LFGs) with high percentages of greenhouse gases and thus contribute to climate change. It also consumes valuable land which could be converted into revenue generated assets. In 2011, India needed 380 km2 areas for waste disposal which will be 660 km2 by 2030. In 2016, the India Government has amended the Solid Waste Management Rules (SWM) for effective and proper management of MSW and reclaim the large old dumps by closure and recommend rehabilitate by a feasible solution in terms of reduction of waste by biomining. Biomining concept is an innovative, environmentally acceptable, economically and practically feasible and rapid measure to remediate the old open landfill site to successfully bring to zero emission of LFGs and leachate and also reclaim the land reusability and zero maintenance. In this study, the concept and utility of biomining as a key part of sustainable landfill management especially for the rehabilitation of MSW dumpsites in different megacities in India have been discussed.

Paeniglutamicibacter quisquiliarum sp. nov., isolated from midden soil waste.

A Gram-stain-positive, irregular short-rod and non-motile bacterium, designated strain ABSL32-1T, was isolated from a soil sample collected from the Suphan Buri municipal solid waste disposal area. According to the results of a polyphasic taxonomic study, a novel species belonging to the genus Paeniglutamicibacter was described. Strain ABSL32-1T grew optimally at 20-25 °C and at pH 6.0-8.0 in the presence of 1 % (w/v) NaCl. The whole-cell sugars were ribose, mannose and glucose. The peptidoglycan structure contained A4α peptidoglycan (Lys-Glu; A11.54). The polar lipids contained digalactosyldiacylglycerol, diphosphatidylglycerol, phosphatidylglycerol, unidentified phospholipids and two unidentified lipids. The major menaquinones were MK-9 and MK-10. The major cellular fatty acid was anteiso-C15 : 0 (70.1 %). Based on 16S rRNA gene sequence analysis, strain ABSL32-1T showed the highest similarity to Paeniglutamicibacter sulfureus DSM 20167T (99.5 %), followed by Paeniglutamicibacter antarcticus SPC26T (99.0 %) and Paeniglutamicibacter psychrophenolicus AG31T (98.8 %). The genome of strain ABSL32-1T is 4.4 Mbp with a DNA G+C content of 66.0 mol%. The average nucleotide identity values between strain ABSL32-1T and the type strains P. sulfureus DSM20167T, P. antarcticus SPC26T and P. psychrophenolicus AG31T were 86.6, 74.7 and 83.6 %, respectively. On the basis of phenotypic, chemotaxonomic and genotypic properties, strain ABSL32-1T is proposed to represent a novel species to be named Paeniglutamicibacter quisquiliarum sp. nov. The type strain is ABSL32-1T (=TBRC 14976T=NBRC 115252T).

Implicit reminders of reputation and nature reduce littering more than explicit information on injunctive norms and monetary costs

The present research addresses tools that could help reduce littering in society. Four interventions were tested which, based on different processes, should reduce littering: monetary information, the depicted injunctive norm, watching eyes and a nature picture. To test these interventions, a randomized controlled trial (RCT) involving 440 community building's waste disposal areas (N = 71,155) was conducted in Vienna. Littering was assessed before the intervention, 24–48 h after, and again seven weeks after the intervention. Results show that the financial intervention (monetary information) hardly had any effect on littering whereas the norm-based intervention (depicted injunctive norm) led to more littering compared to the control and in particular, the nature picture. In contrast, the reputation-based intervention (watching eyes) and ecology-based intervention (nature picture) reduced littering over time by 4.7%. Thus, interventions based on implicit and soft appeals to reputation and ecology are more effective in fostering clean environments than classical interventions applying explicit information on finances and norms.

Evaluation of Landfill Site Selection by Combining Fuzzy Tools in GIS-Based Multi-Criteria Decision Analysis: A Case Study in Diyarbakır, Turkey

Solid waste disposal is one of the important environmental and socioeconomic problems faced by city managers with the increase in urban population. To overcome this problem, landfilling is a common and effective solution used by municipalities frequently. This study aims to assess and identify suitable potential areas for municipal solid waste disposal. For this purpose, a criteria determination and evaluation commission consisting of experts from various institutions and disciplines was established. Fourteen criteria, including environmental, economic and sociocultural sensitivities, were selected via the experience of an expert team and a wide literature search. The criteria used in this study were standardized by using fuzzy membership functions and feature values turned into continuous values. The Stepwise Weight Assessment Ratio Analysis (SWARA) method, in which expert opinions are effective, was used to determine the criterion weights. A site suitability map was obtained by using the Weighted Linear Combination (WLC) method with standardized thematic maps and the criterion weight variables. As a result of this study, 3.44% of the total study area was determined suitable for a solid waste storage area. These determined areas were found in different locations of study and numbered on the map and each of them was selected as an alternative storage area candidate. Developed methodology was validated via exploration and observation of candidate areas by the expert team. The proposed methodology can be used for similar scale cities with its ease of use, flexibility and expert opinion.

EFFECT OF SOCIAL MARKETING ON SUSTAINABLE BEHAVIOUR TOWARDS HOUSEHOLD WASTE DISPOSAL IN LAGOS STATE, NIGERIA

The study seeks to determine the influence of social marketing on sustainable behaviour in the area of household waste disposal in Lagos State, Nigeria. This study focuses on four dimensions of social marketing namely: social product, social price, social promotions and social place. Descriptive research design was employed using cross-sectional survey methods for data collection. Three hundred and ninety one (391) respondents were used for the study. Four research questions were raised and answered through corresponding hypotheses. Data were analyzed using descriptive and inferential statistics. Findings indicated a convincing relationship between sustainable behaviour and social marketing particularly the elements of price and place; and by extension, implications for improvement is that decrease in price associated with waste disposal billings might cause individual household to dispose waste appropriately and more importantly regular maintenance of waste collection site in other to discourage road side waste disposal.

Mapping the impact of a large municipal waste disposal area on surface water: 1993–2017, case of Laogang, Shanghai

In China, the impact of waste disposal facilities is always a cause of concern for the government and the public. Laogang Municipal Waste Disposal Area (LMDA), Shanghai, one of the largest municipal waste disposal areas in the world was selected as case in this study, and it was attempted to analyze the changes in the surface water quality, and map the impacted area by LMDA on surrounding streams from its operation period of 1993–2017. The results showed that, during the whole period, only biochemical oxygen demand (BOD5) showed a continuous improvement with a percentage of 85.92%, however, chemical oxygen demand (CODcr), ammonia (NH4+-N) and total phosphorus (TP) significantly improved but BOD5 slightly deteriorated began from 2013. Using spatial analysis tools and Kendall’s concordance test, CODcr and phenol at LMDA showed a significant impact on surrounding surface water; especially, the impacted area for CODcr decreased from 106.30 km2 to 22.86 km2 from 1993 to 2017, which dropped from 4.3 to 0.9 times the area of LMDA. Surprisingly, NH4+-N and TP at LMDA were affected by the surrounding streams, instead of having an impact on them. Interestingly, heavy metals and non-metals such as Hg, As, Zn, and Se in the surrounding streams were unlikely affected by LMDA. The driving forces for surface water quality improvement included the eco-remediation of closed unsanitary landfills, upgrade in waste shipping and terminals, operation of sanitary landfills and incineration plants for landfill diversion.Capsule: Impacted area of municipal waste disposal area is not so large.

Municipal Solid Waste Management in the Czech Republic and in Slovakia

Abstract Contracting waste management services is one of the most commonly used approaches to the delivery of this service and this topic is clearly in the focus of frequent academic research. The goal of this article is to examine trends in the area of solid waste collection and disposal on the municipal level for the Czech Republic and Slovakia in terms of developments over the past 20 years with a focus on the share of inter-municipal cooperation in the delivery of this service. In contrast to Western European countries, which are undergoing re-municipalization, the data obtained for Slovakia and the Czech Republic over 20 years show that the municipal solid waste management service is dominated by contracting, which has increased over the examined period. This fact is apparently a reflection of the high rate of fragmentation in municipal structures and the low willingness among municipalities to cooperate. The data obtained also indicate that using external suppliers seems to bring marginal savings that could certainly be substantially larger; potential increases in efficiency via contracting are unequivocally limited by the low quality of contract management. Regarding our core question, we found that the proportion of inter-municipal cooperation between service delivery modes did not significantly increase during the investigated period. The experts interviewed almost uniformly agreed on three critical limits related to the issue of inter-municipal cooperation in MSW management delivery – transaction costs of different types, non-existent regular comparisons of best solutions, and limited motivation to select optimal service delivery modes.

A Circular Economy Approach to Restoring Soil Substrate Ameliorated by Sewage Sludge with Amendments.

This study examined the use of an artificial soil substrate in a mine waste reclamation area and its effect on plant metabolic functions. Research was conducted by determining the relationship between the plants’ biochemical features and the properties of plant growth medium derived from post-flotation coal waste, sewage sludge, crushed stone and fly ash on the surface of the mine waste disposal area. Trees and shrubs were established on the material and allowed to grow for eight years. The study determined that the applied plants and the naturally occurring Taraxacum officinale were suitable for physio-biochemical assessment, identification of derelict areas and reclamation purposes. An evaluation of a soil substrate applied to post-mining areas indicated that it was beneficial for plant growth since it activated the metabolic functions of herbaceous plants, shrubs, and trees. The study showed that soil substrate can be targeted to improve plant stress tolerance to potentially toxic elements (PTEs). These data suggest the potential for growth and slower susceptible response to Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn. It is possible that the constructed soil-substitute substrate (biosolid material) would be an effective reclamation treatment in areas where natural soil materials are polluted by PTEs. This observation may reflect a more efficient use of soil substrate released from the cycling of organic biogene pools, in accordance with the circular economy approach. In further studies related to land reclamation using sewage sludge amendments, it would be necessary to extend the research to other stress factors, such as salinity or water deficiency.

Soils of the Ribeira Valley (Brazil) as Environmental Protection Barriers: Characterization and Adsorption of Lead and Cadmium

In waste disposal areas, soils can be used as environmental protection barriers to retain potentially toxic metals. Although most studies focus on lateritic soils, it is still of interest to evaluate other soil types, aiming to select the best materials among those available near the contamination area, reducing costs and construction efforts. This paper characterizes and evaluates the behavior of 13 soil materials collected in a region (Ribeira Valley, Brazil) with a history of improper mining waste disposal for the retention of lead (Pb) and cadmium (Cd) and their possible use as environmental protection barriers. All soils were acidic, kaolinitic, with negatively charged particles. Soils were grouped into three classes according to soil properties, such as particle size distribution, cation exchange capacity (CEC), and specific surface area (SSA), using cluster and principal component analysis. The Pb and Cd adsorption capacities ranged from 288 to 479 µg g−1 and 207 to 326 µg g−1, respectively, obtained from batch equilibrium tests. In general, all soils presented suitable characteristics for the retention of Pb and Cd, but four of them (1 to 4) showed the highest adsorption capacities, probably due to their larger SSA, CEC and percentage of fines (clay + silt).
