Environmental Impacts of the Existing Solid Waste Management System of Northern Lahore

Municipal solid waste management (MSWM) constitutes one of the most crucial health and environmental problems facing authorities in the Arabian Gulf. Recent literature on current solid waste management (SWM) in Qatar has been reviewed in this paper, and a focused study has been carried out to provide a review on the total amount of municipal solid waste generated, stored, collected, disposed as well as the constituents of the waste. The analysis showed that Qatar produced around 2,000,000 tons of solid municipal waste annually, corresponding to a daily generation rate per capita of about 2.5 kg. About 60% of MSW is organic material and about 300 kg is composed daily. Landfill and composting is considered the most appropriate waste disposal techniques in Qatar. Um-Al-Afai landfill has nearly 80% of MSW. Because of the increased migration in Qatar, there is a sharp rise in the volume and also in the variety of solid waste. It is important to alleviate societal concerns over the increased rate of resource consumption and waste production; thus, policy makers have encouraged recycling and reuse strategies to reduce the demand for raw materials and to decrease the quantity of waste going to landfill. An example of the benefit of mechanical recycling of plastics compared to land filling and composting was conducted by GaBi 4 life cycle analysis tool which showed the benefits to the global warming and human toxicity. Recycling is the favored solution for plastic waste management, because it has a lower environmental impact on the defined impact categories, from Global Warming Potential (GWP) and Human Toxicity Potentials (HTP) indicators.

Nigeria just likes every other country in sub-Sahara Africa is faced with solid waste generation and management. Solid waste is dump indiscriminately and seen in huge heaps on any piece of unused land, around buildings, drainage system, institutions, playing ground, roads side, and in the open market places in major cities and towns. Living with solid wastes littered around seems to be an acceptable way of life among the people in this part of the world. This research work reported intensive review on solid wastes generation and management in this region using Nigeria as a case study. The application of knowledge of solid waste generation and management approach is crucial for inculcating a change of attitude towards improving the management of generated solid waste in this region. From the review, it was observed that biodegradable solid waste that can be managed via the biogas technology and landfill technology have the highest percentage fraction while the remaining fraction that comprised of non-biodegradable and combustible solid waste can be managed via other technology such incineration, gasification, pyrolysis, etc. Besides, the inefficient management of generated solid waste by individuals, households, institution, consumers and waste management companies can be attributed to inadequate information on waste management benefits, insufficient academic research and industry linkages, financial constraint, economic constraint, cultural constraint, lack of planning and projection, social constraint, lack of producers’ involvement in waste management as well as poor implementation of government policies and lack of comprehensive legal framework.Keywords: Solid waste generation, solid waste management, biodegradable solid waste, combustible solid waste

Determinants of municipal solid and hazardous waste management in the occupied Palestinian territory: a cross-sectional study

Solid waste management is a challenge both at the global level and the local level. Solid wastes must be properly managed by determining that they are hazardous wastes. Methane is the major greenhouse gas, which emit from landfill areas and contribute significantly to global warming. Moreover, that the global warming potential of methane is 21 times higher than that of carbon dioxide and it has highest generation (60%) than other gases. The composition of municipal solid waste (MSW) in developing countries has higher (40%-60%) organic waste. This would have potential to emit higher GHG's from per ton of MSW compared to developed world. Beside that landfill areas in India are not planned. This leads to uncontrolled emission of trace gases, foul smell, bird menace, ground and surface water pollution, etc. In the present paper, we had quantified the methane emission from the MSW landfill areas of Kota City.

Solid waste management in Malaysia is under the responsibility of the Solid Waste and Public Cleansing Management Corporation or commonly known as SWCorp. It is licensed under the National Solid Waste Management Department, a department directed by the Ministry of Urban Well-being, Housing, and Local Government. SWCorp is responsible for setting up policies on solid waste management under the direct overview of the ministry. Solid waste management in Malaysia has undergone various levels of transformation from managing generated solid waste such as reusing and recycling before 2015 to reducing and segregating solid waste at source since 2015. The management of solid waste at source is emphasized by the enforcement of the 672 Act: Solid Waste and Public Cleansing Management Act 2007 in September 2015. Nevertheless, behavioral transformation requires a commitment to social responsibility, namely reducing, reusing, and recycling activities, in all sectors of the community. This chapter discusses and examines Malaysian consumers’ commitment to social responsibility in solid waste management from the perspectives of NGOs and youth. The consumer sector is the most crucial group in the community as it represents the main grassroots. Furthermore, the commitment at grassroots is more sustainable and longstanding compared to top-down enforcement. Additionally, given that NGOs are more sensitive to the transformation of public behavior, and youth are our future decision makers on the fate of the environment, this chapter discusses consumers’ commitment to social responsibility in waste management through the perspectives of NGOs and youth. The analysis regarding the commitment of Malaysian consumers through the perspectives of NGOs and youth indicates that Malaysian consumers are more committed to performing recycling and reusing activities as compared to reducing activities. These findings illustrate Malaysian consumers’ reluctance to embrace the philosophy behind behavioral transformation, that is prevention is better than cure. In this case, they are slow to adapt to the behavioral transformation activities related to reduce, segregate, and compost solid waste at the source.

LLactic acid bacteria (LAB) are used widely in food microbiology as probiotics and biopreservatives to extend shelf life of food items. Lactic acid produced by LAB strains are precursor of polylactic acid(PLA) that has growing demand as bioplastics that are biodegradable in nature replacing traditional plastics. LAB have the potential to utilize polysaccharides from various sources and produce lactic acid. The aim of this study is to identify lactic acid producing strains of lactic acid bacteria(LAB) that have efficiency in utilizing biodegradable fragment of domestic solid waste collected from residential areas of Coimbatore municipality for three days. The main objective of this study is to convert the biodegradable solid waste into lactic acid, a precursor of Poly lactic acid- PLA used as bioplastic. Important chemical parameters of the solid waste like phosphate estimation, nitrate estimation, Total organic carbon estimation were done following Indian standard analytical methods. Glucose consumption efficiency of Lacto bacillus sp.in solid waste substrate was analyzed in UV spectrometer at620nm by Anthrone method. Estimation of lactic acid produced was done in UV spectrometric analysis at 390nm using iron lactate formation. In this study, lactic acid bacteria were isolated from samples of milk, curd, idli batter and screened for lactic acid production. Three isolates were chosen for the study each one from milk, curd, idli batter and from biochemical tests and morphology confirmed as Lacto bacillus sp. Solid waste collected was pretreated with dilute acid heating and hydrolysate obtained was used as substrate for lactic acid production under optimized parameters. Three different substrates were chosen for lactic acid production and the results were compared. The three isolates of Lacto bacillus sp.were good producers of lactic acid and utilized biodegradable solid waste in an effective manner. 3-5 gm/lit of lactic acid was produced by the three strains of Lacto bacillus sp .Segregation of domestic solid waste collected, comprised of 40% biodegradable fragment, 40% nondegradable plastic, 20%miscellaneous waste. Lactic acid production from biodegradable portion is a preliminary step experimented in this study progressing in polylactic acid PLA pathway indirectly reducing plastic pollution. In a similar manner, nonbiodegradable plastic waste can be minimized using Exopolysaccharide pathway by Xanthomonas sp.that is reviewed in this study. Disposal of solid waste in an economical and greener way is a smart method of saving environment. Bioconversion of plastic into pseudoplastic xanthan gum by Xanthomonas sp.(through exopolysaccharide pathway) are greener techniques to crush down the accumulated plastic mountains to ground level.

Problem setting. One of the most actual environmental problems in Ukraine is the accumulation and utilization of the solid household waste. Due to the considerable volumes of garbage accumulation, Ukraine is considered to be the one of the most technically inflicted countries in the world. In its experience of solid domestic waste treatment, our state is for a few decades behind the developed countries of Europe. There are tens of thousands of spontaneous dumps in Ukraine and more than 6 500 official landfills.Recent research and publications analysis. The analysis of researches on the assessment of the status of waste disposal sites in Ukraine has shown the lack of scientific works on the integrated assessment and forecast of solid waste landfills’ state and the minimization of their impact on the environment. The imperfection of modern measures to minimize the impact of dumps on the environment and the lack of an effective monitoring system necessitate the development of a set of measures to ensure the ecological safety of landfills.Aim of the article. To study the problem of solid waste accumulation and utilization in Ukraine and to identify ways of public governance’s improvement in the sphere of dealing with them.Main material. Hundreds of thousands of tons of solid household waste are being collected annually in urban landfills. Location, arrangement and operating conditions of most sewage dumps do not meet regulatory requirements, this increases the ecological danger of these objects. There are about 2000 objects in Ukraine, which are organized without projects and engineering and hydrogeological exploration. The consequence of this is the pollution of groundwater by filtrate and the migration of pollutants along with ground and underground flows.Due to widespread problems with solid household waste throughout Ukraine, the entire power vertical faces this question. At the local level, attempts to start a business in the sphere of waste sorting and recycling have taken place for several years. There are a lot of reports on the building of waste sorting and waste recycling enterprises in different regions of Ukraine.The garbage market, where it would be possible to sell secondary raw materials, has not yet been developed in Ukraine. According to experts, for example, waste produced only by the capital itself, can be estimated at 3 billion UAH in a year. Thus, tens of billions of hryvnias can be got for the country’s secondary raw materials. It has been estimated, that 100 waste processing plants are needed in order to clean the country from garbage.Taking into account the general difficult economic situation in the country, experts see the solution of this issue in attraction of foreign investments into the construction of such enterprises. For Ukraine there is a need for a state waste management strategy.Positive trends in the sphere of state regulation of the waste management system can be seen in recent years, but Ukraine has not created the appropriate legal and regulatory framework yet that would gradually reach the requirements of the European legislation. Conclusions of the research. The enshrined regulations of national rules on disposal and solid waste management are currently not implemented fully. This calls for the improvement of enforcement practice on this issue, as well as the introduction of amendments and additions to existing legal acts. It is necessary to develop an effective state program that would include a complex of state measures for the creation of specialized enterprises for sorting and processing of solid waste in Ukraine, to conduct a series of educational actions among citizens. Ukrainian legislation on the effective solution of the problem of solid household waste management should be based on national characteristics and positive experience of relevant European legislation in this sphere. And the attraction of foreign investments in the waste recycling industry will definitely contribute to the improvement of the ecological situation in Ukraine.

The main aspects of solid waste management in an area are the quantities, compositions and characteristics, as well as its current management situations. Elephant Study Center (or Elephant Village), well known by Thais and foreigners, presently lacks of data on generated solid waste quantities, compositions and characteristics, including its management. This study investigated the quantities using purposive sampling of solid waste containers, the compositions according ASTM D 5231-92 standard, and some characteristics, i.e. bulk density, moisture content and total solid, using weighting and weight differences. In addition, the current solid waste management problems, community participation levels, and recommendations were studied by using questionnaire and interviews. The results found that the average amount of solid waste was 138.44±15.42 kg/d. The compositions were 17.50%, 47.20%, 30.17% and 5.13% of organic waste, general waste, recyclable waste and other wastes, respectively. Besides, the characteristics of bulk density, moisture content and total solid were 0.037±.003 kg/l, 57.75±6.85% and 42.44±6.78%, respectively. For the results of current solid waste management, the highest problems were: lack of solid waste management system (4.27±1.16), disarranged disposal (3.78±1.26) and lack of solid waste separation system (3.40±1.34), respectively. The lowest community participation levels in solid waste management were: campaign in using cloth bags, food boxes and baskets for reducing plastic bags and plastic foam (1.82±0.85), problem and cause searching of solid waste management (1.90±0.77) and performance in solid waste management following hygiene or sanitary perspectives (1.91±0.80), respectively, with the overall at lowest level (2.09±0.20). Besides, there was no community participation in solid waste management from interviews. Therefore, community should participate in solid waste management following sanitary solid waste management principle for sustainable management.

We present a methodology to develop the integrated toxicity and climate change risk assessment of Europe based facilities, industries and regions. There is an increasingly important need for large scale sustainability measurement solutions for company reporting with high granularity. In this paper we measure key aspects of Sustainable Development Goals in terms of human, cancer and non-cancer toxicity, ecotoxicity together with global warming impact potentials from point source pollutant releases of more than 10,000 companies and their 33,000 facilities in Europe from 2001 to 2017, by using the European Pollutant Release and Transfer Register. For our assessment, we deploy a scientific consensus model, USEtox for characterizing human and ecotoxicological impacts of chemicals and the global warming potential values from the Intergovernmental Panel on Climate Change. We discuss water and air emissions of dozens of pollutants in urban, rural, coastal and inland areas. Companies in the electricity production sector are estimated to have the largest human toxicity impact potential (46% of total) and the largest global warming impact potential (50%), while companies in the sewerage sector have the largest ecotoxicity impact potential (50%). In the overall economy, the correlation between facilities’ global warming and toxicity impact potentials is positive, however, not very strong. Therefore, we argue that carbon footprint of industrial organizations can be only used as a climate change risk indicator, but not as an overall environmental performance indicator. We confirm impact potentials of major pollutants in previous research papers (Hg accounting for 76% of the total human toxicity and Zn accounting for 68% of total ecotoxicity), although we draw the attention to the limitations of USEtox in case of metals. From 2001 to 2017 total human toxicity dropped by 28%, although the downward trend reversed in 2016. Ecotoxicity and global warming impact potentials remained unchanged in the same period. Finally, we show that the European pollutant release monitoring data quality could be further improved, as only three quarters of the toxic releases are measured in the Member States of the European Union, and a high share of toxic pollutant releases are only estimated in some countries. Of the measured or calculated toxic releases, only one third is reported according to the most robust CEN/ISO standards and about one fifth according to the least preferred other methods, like engineering judgements.

Innovative frameworks and strategies for solid waste management have been brought forward by researchers to solve the phenomenon of accumulating waste in the environment globally. The sustainability of medical waste management then pivots on the ability of waste management in a way that proves harmless to humans, animals, plants and the environment at large. This review looks into the strategies for the sustainable management of solid waste generated in the health institutions of Zimbabwe. Waste management includes waste generation, waste segregation, waste storage, waste collection and transportation, waste treatment and disposal and waste reuse and recycling. Exhaustive literature review was conducted as the methodology for this review soliciting information on the solid medical waste management status worldwide. In Zimbabwe, hazardous medical solid waste segregation, storage, transportation and disposal is a responsibility of the medical institutions generating the waste. These include trip and fall hazards, infectious hazards, cuts and lacerations, drugs addictions and radioactive hazards. The environment also faces contamination to the land, underground water bodies through leaching, surface water bodies, damage to flora, poisoning of fauna and contamination of the atmosphere by methane and carbon monoxide. Findings of the study show that innovations for medical solid waste management include frameworks such as the Ladder of Lansink and the three 'R's. Innovative technologies include rotary kiln incinerators, automated segregation and engineered landfills. Therefore, the framework addresses issues impeding the adoption of these innovative strategies in Zimbabwe.

Solid waste management is now acknowledged as one of the major environmental issues of our times. It remains a challenge for developed countries and is an exponentially growing problem for developing countries. The last four decades are marked by several incidents highlighting problems with solid and hazardous waste management across the world. 1. Trans-boundary shipments of hazardous and solid waste have received world-wide attention and media headlines. Infamous examples include Khian Sea which started its journey from Philadelphia in 1986 and Mobro which started its journey from New York in 1987; two US barges or ships with cargoes of municipal solid waste that went from one country to another looking for a port to dump their wastes. The Mobro went all the way to Belize and brought its cargo back to Brooklyn, New York for incineration and landfilling. Many speculate that Khian Sea dumped its cargo somewhere in the Indian Ocean in 1988. 2. Most recently, a fire started on 27 January 2016 in India’s oldest and largest open dumping site, Deonar in Mumbai, and was visible in satellite images (shown in Fig. 1.1). It continued for several days leading to complaints of air pollution and closure of schools for 2 days. The massive fire was attributed to the buildup of methane gas in the open dump where the waste had reached heights of more than 30 m. Fires in this dumping site have been recurrent making living conditions in the surrounding areas extremely difficult. 3. Many sources have identified poor solid waste management as one of the major contributing factors to the spread of plague in Surat, India in 1994. Incidents like these led to promulgation of the Municipal Solid Waste (Management and Handling) Rules in India in 2000. 4. Several industrial sites all around the world remain unusable or a toxic nuisance for their neighbours due to improper handling and management of hazardous wastes on-site. One of the earliest and most cited examples in the USA includes Love Canal, Niagara Falls, New York, where toxic waste was dumped through the 1920s and got national attention only in 1976–1978. The Superfund program (under the Resources Conservation and Recovery Act, RCRA for ensuring proper disposal of solid and hazardous waste) was initiated in 1980 in the USA and was the government’s response for remediating and rehabilitating such contaminated industrial sites.

Objective: The general objective of this study is to analyze the governance and challenges of the carbon credit market, focusing on the comparison between industrial waste and solid waste in Rio de Janeiro. To achieve this objective, the following specific objectives were established: to examine the history and evolution of the carbon credit market; to analyze the global and Brazilian energy scenario and its impact on the greenhouse effect; to investigate the principles of the Clean Development Mechanism (CDM) and its applications; and to evaluate the management of solid and industrial waste in the context of carbon credit. Theoretical Framework: In the early 1980s, the idea of exchanging the national debt of developing countries as a means of preserving natural resources emerged, establishing a model for carbon credits (Albuquerque et al., 2021). Carbon credits are one of the strategies adopted at national and international level to mitigate the increase in greenhouse gas concentrations in the atmosphere. Method: The methodology adopted for this research involves analyzing the governance and challenges of the carbon credit market, with a focus on comparing the management of industrial waste and solid waste in the state of Rio de Janeiro. Comparative analysis is a central part of the study, which examines the differences and similarities in industrial and solid waste management, with the aim of understanding how these practices impact the carbon credit market. Results and Discussion: The results show that the information presented on urban solid waste management in the state of Rio de Janeiro reveals a challenging scenario that requires coordinated action between the state, municipalities and the various sectors of society. The average generation of solid urban waste per capita is 1 kg per day, totaling approximately 6,596,840.90 tons per year in the state (Inea-RJ, 2023). The inadequate disposal of this waste over the decades has caused environmental, social and economic problems. Research Implications: The practical and theoretical implications of this research are discussed, providing insights into how the results can be applied or influence practices in the field of governance in the carbon credit market in the context of solid and industrial waste management in the state of Rio de Janeiro, demonstrates that inadequate waste management has been a challenge, generating environmental impacts and limiting the potential for recovery and reuse of materials. In a scenario where the average generation of urban solid waste per capita is 1 kg per day, totaling approximately 6,596,840.90 tons per year, the implementation of sustainable solutions, such as the creation of a carbon credit market, can offer viable alternatives to mitigate these problems. Originality/Value: This study contributes to the literature as the governance and challenges of the carbon credit market in the context of waste management in Rio de Janeiro reflect the complexity of the interactions between production, consumption and disposal. The implementation of integrated policies and the promotion of sustainable practices are essential to overcome current challenges and create opportunities for economic and environmental development.

The scientific article is devoted to the public administration of solid household waste management as a direction of consumer rights protection. Attention was drawn to the positive aspects of public administration regarding the management of solid household waste as a means of protecting consumer rights (for example, in the Dnipropetrovsk region): the existence of the National Waste Management Strategy in Ukraine until 2030; availability of a regulatory and legislative framework in the field of management and handling of solid household waste; availability of "Methodical recommendations for the development of regional waste management plans”; existence of a solid household waste management program in the Dnipropetrovsk region for 2022-2024; positive experience of the EU and other developed countries in the field of effective management and handling of solid household waste; the presence of a solid household waste collection and disposal system; availability of municipal solid waste landfills; availability of enterprises for processing, processing and disposal of hazardous components of solid household waste; initiation of elements of separate collection of solid household waste; gradual formation of awareness among the population regarding the need to separate resource-valuable components from the general flow of solid household waste. It was concluded that the problematic issues in public administration regarding the handling of solid household waste as a direction of consumer rights protection (for example, in the Dnipropetrovsk region): the tendency to increase the scale of generation and accumulation of solid household waste; lack of a systematic approach to creating effective management and handling of solid household waste; insufficient funding of solid waste management and management; low level of implementation of previous regional solid waste management and handling programs; low level of utilization of resource-valuable components of solid household waste; lack of waste transfer stations and waste processing enterprises, etc.
