Abstract:
Improving the understanding of the stabilization process is of great significance to guide the sustainable development of municipal solid waste (MSW) landfills. An evaluation system of the stabilization process of MSW landfills has been established. The indices of the evaluation system involve the degradation degree of MSW, the release of landfill gas production potential, and the settlement of landfills. Based on the biochemical-consolidation-solute migration coupled model, an evaluation method of the MSW landfill stabilization process is proposed by combining field tests with numerical simulation. The stabilization process of the Jiangcungou landfill in China is investigated by using the proposed method. The analyzed results show that the stabilization process of high kitchen waste content landfills can be divided into three stages, which is different from the stabilization process of landfills in developed countries. For the Jiangcungou landfill, the ratio of cellulose to lignin in MSW decreases rapidly during the fast degradation stage when obvious settlement occurs. During the slow degradation stage, the hydrolysis rate is slow and settlement develops slowly. When the landfill reaches the stabilization stage, the ratio of cellulose to lignin of MSW changes very slowly; most of the landfill gas potential has been released; the settlement stabilization is completed basically. The change processes of the three evaluation indices are different, of which the degradation stabilization index is the main one. According to the findings above, leachate recirculation is recommended to adjust the degradation environment in the landfill, which can be helpful to avoid acidification at the fast degradation stage. Temporary cover is suggested to improve landfill gas collection efficiency at the beginning of the stable methanogenic stage. The landfill site closure should be operated when the settlement rate is low.

Abstract:
Heterogeneous composite wastes from landfills were evaluated as precursors for the generation of activated carbon (AC). A single-step chemical activation process was applied involving irradiation with microwave energy and impregnation with KOH. The average percentage yield of AC from active landfill precursor was higher than that from closed landfill for all depths sampled. Increase in impregnation ratio and irradiation power decreased the average percentage yield for both landfill precursors (active: 38.1 to 33.1%; closed: 42.1 to 33.3%). The optimum pH range for adsorption of methylene blue was pH 6–7, while adsorption increased with increase in temperature over the range 30 to 50°C. Carbonyl and hydroxyl groups were the major functional groups on the surface of AC. The properties of the AC are potentially suitable for the removal of cationic dyes and pollutants. AC generated from the landfill composite was comparable to that from other biomass being managed through AC generation. This is the first report to demonstrate the possible reuse of landfill composite as AC. The reuse option of landfill composite could provide a means of sustainable management of landfilled municipal waste.

Abstract:
(Enhanced) landfill mining (ELFM) is a sustainable waste management strategy which supports the circular economy and reduces the environmental risks related to landfills. To facilitate and encourage stakeholders to launch (E)LFM-projects, RAWFILL has developed (1) an Enhanced Landfill Inventory Framework (ELIF), (2) an innovative landfill characterization methodology combining geophysical imaging and guided sampling (HADESS) and (3) a two-step Decision Support Tool (DST) to allow smart (E)LFM-project planning and prioritization. Based on the Interreg Europe COCOON experiences, the (E)LFM-concept was broadened to Dynamic Landfill Management (DLM), a sustainable and active long-term management of former landfills. DSTs improve decision-making by increasing the efficiency and lowering the uncertainty. The two-step approach offers an efficient and cost-effective solution. The DST 1 (Cedalion) requires limited data and provides guidance to the next step. The result is a ranking score on 4 scenario’s: waste to materials, waste to energy, waste to land interim use. The DST 2 (Orion) provides an overview of relevant tools that can assist the user in the further project development, like estimations about the feasibility of a business case, simulating scenario’s or finding sustainable interim solutions. The latter, interim use, is the novelty in this dual DST and should be seen as a loop in the roadmap. To summarize, the innovative approach of RAWFILL is the broadening of the resource scope at landfills and their comprehensive management, spanning the whole project cycle: from first screening to final redevelopment, including sustainable management and interim uses.

Abstract:
Background: A new generation of the sustainable landfill is designed to achieve sustainable Municipal Solid Waste (MSW) management. It is hybrid anaerobic/aerobic biodegradation landfill followed by landfill mining. However, there is limited information on landfill mining, especially the criteria and process for the practitioner to determine the end of the landfill biodegradation to commence landfill mining. Objective: Hence the overall objective of this research was to develop a comprehensive resource mining plan for bioreactor landfills. </P><P> Method: When waste decomposition becomes slower or stopped, the landfill can be mined to recover resources and utilize the recovered space. The amount of the gas generated, landfill temperature and landfill settlement are indirect measures of landfill activity. Also, the concentration of cellulose (C), hemicelluloses (H), and lignin (L) can describe the biodegradable fractions of waste. Hence the biodegradation in landfills can be monitored by recording the change in methane production, temperature, settlement and the (C+H)/L ratio of waste. Once methane recovery is minimal, landfill reaches a maximum settlement and, ambient temperature plus the (C+H)/L value reaches a stable value of 0.25 indicating end of biodegradation. At this point landfill resources including compost material, non-recoverable waste, and recyclables such as plastics, metal and glass can be mined and recovered. Compost and recyclables can be sold at market value and the non-recovered waste with high energy content can be used as refuse-derived fuel. Once the landfill has been mined space can be reused thus eliminating the need to allocate valuable land for new landfills. </P><P> Result: The landfill mining detailed in this manuscript utilizes principles from single stream type recycling facilities to ensure feasibility. The first landfill will be excavated and screened to separate the biodegraded soil and compost fraction from the recyclables. Then the screened recyclable materials are transported for further processing in a single stream type separation facility where they will be separated, bundled and sold. Conclusion: A cost calculation was performed for the resource mining of Calgary Biocell and if the mined resources are sold at market values, then the mining of Calgary Biocell would generate approximately $4M.

Abstract:
Poor management of dump-sites creates significant risks to environment and human health. Thus, sanitary landfills are required to be more effective to minimize the impacts of waste disposal. This research assesses the environmental economic evaluation focused on the economically efficiency of Malaysian sanitary landfills. Two landfills were selected based on their different operation. Landfill A incurred RM 128 million (USD 41.8 million) as the total cost within 20 operational period. Thus, it is estimated that the cost may be covered within 15 operational years. On the other hand, the total costs for Landfill B are estimated at RM 198 million (USD 64.8 million) with RM 245 million (USD 80.2 million) are expected to be obtained as profit within eight operational years. Landfill B has high initial costs of design and construction. However, the costs are covered within the first five years. This is because Landfill B introduces a new green technology namely landfill-gas power generator. This indicates that, Landfill B has stronger market competition ability as compared to Landfill A. It can be concluded that the implementation of green technology namely landfill gas harvesting system has higher impact to improve the economic value of a landfill thus making it more economical and environmentally sustainable.

Abstract:
Landfilling is one of the most widely used forms of solid waste disposal, yet the management of landfill leachate is challenging because of the complex composition and high contaminant concentration. This study provides an on-site treatment system to treat 500 m3 day-1 of the leachate generated from the Perdido Landfill in Escambia County, Florida. The main concerns of the landfill leachate are ammonium-nitrogen, total dissolved solids (TDS) and biological oxygen demand (BOD) from the long-term monitoring (from September 1999 to May 2015). To target these major contaminants as well as other pollutants, we designed a wetland treatment system by fully utilizing the existing facilities at the Perdido Landfill site. The modified wetland treatment system consists of five components in series: leachate collection/aeration ponds, anaerobic ponds, aerobic ponds, wetlands and limestone filter ponds. The leachate collection/aeration ponds provide functions of nitrification as well as ammonia and CO2 stripping. The following anaerobic ponds focus on nitrogen removal by denitrification. The BOD is removed in the aerobic ponds. The TDS are removed in the wetlands and limestone filter ponds. In the wetlands, 60% of chloride and 40% of other contaminants are absorbed by Parthenium sp. In the limestone filter ponds, bicarbonate, calcium, magnesium and iron are removed.

Abstract:
Open disposal is the most common technique used for municipal solid waste (MSW) management due to the absence of sanitary landfills in Pakistan. The major cities and small towns in Pakistan have become a showcase of negligence and mismanagement of MSW, which results in deterioration of the environmental and social-life quality. Moreover, research has proved that inefficient handling (disposal) of MSW results in uncontrolled emissions of greenhouse gases (GHGs), mainly methane, and adds a significant share in global climate change. This study aims to estimate methane emissions from MSW disposed of at dumpsites and compare the GHG mitigation potential of different landfill strategies in specific climate and waste compositions in Karachi. The GHG estimations are based on lab-scale investigations conducted by simulating landfill conditions through the landfill simulation reactor (LSR) experiment. The synthetic MSW sample representing the composition of MSW generated in Karachi was used in the LSR experiment. Environmental sustainability and GHG mitigation potential of different landfilling strategies was evaluated by analyzing gas formation potential (GP21) and respiration activity (RI4) at the end of the experiment. This study revealed that the quantity of solid waste annually disposed of at dumpsites in Karachi possesses the potential to release about 3.9 Mt CO2-eq. methane (with specific methane potential of 1.8 tCO2-eq./tonne DM disposed) due to the biological decomposition of the organic fraction. Results show that the fresh waste disposed of at landfill sites in Karachi possesses about 92% and 94% higher GP21 and RI4, respectively, than the German allocated criteria for mechanically and biologically treated (MBT) waste for landfills Furthermore, sanitary landfills with post-aeration conditions showed higher GHG mitigation potential and low biological activity in the waste. The second highest GHG mitigation potential and lowest biological activity of the waste was noticed from bioreactor landfills with post-aeration conditions. The third number in GHG mitigation and reduced waste activity was noticed in the waste sampled from bioreactors without aftercare approach. The least GHG mitigation potential was noticed from the uncontrolled waste dumping (existing) approach with high residual gas potential and respiration index level. This lab-scale landfill simulation study can provide baseline data for further research and planning the development of new sustainable landfills in Karachi, Pakistan and in the region.

Abstract:
Talang Gulo landfill has now been converted into a sanitary landfill system. In the management system, the incoming waste is sorted first. The purpose of this study was to evaluate the process of shorting waste at the Talang Gulo landfill to reduce the waste generation that is the reduction in landfills. This research was conducted by direct observation and using secondary data. The decrease in the number of waste reductions in Jambi City from 2019 to 2020 (9.52% to 1.77%). Data collection during June 2021 shows that the average generation that goes into landfills is 312.44 kg/day. The amount of waste that can be recovered from the shorting process is 2.4% of the total that goes to the shorting facility. The types of waste that are shorted consist of polyethene terephthalate (PET), high-density polyethene (HDPE), polypropylene (PP), low-density polyethene (LDPE), aluminium, and glass. Where in the shorting process consists of two types of processes, namely mechanical and manual. The shorting with the mechanical and manual process obtained the highest PET waste with values, 38.82% and 56.8% respectively. The composition of the recovered waste in the Talang Gulo TPA Shorting Area is as follows LDPE Plastic 10.20%; aluminium 5.21%; Glass 1.30%; PET Plastic 38.83%; HDPE Plastic 24.3% and PP Plastic 20.17%.

Abstract:
In recent decades, population increase and urban development have led to catastrophic environmental consequences. One of the principal objectives to achieve “sustainable development” is to find suitable landfills. Due to their physical characteristics, which have led to a lack of landfill sites and closeness to water bodies, agricultural fields, and residential areas, the cities of Javanrood, Paveh, and Ravansar were chosen as the necessary research regions. On the other hand, these landfills are unable to accommodate the growing urban population. Therefore, this study attempts to develop a framework for spotting the most suitable sites for landfill construction with these three cities as case studies. For this, 10 important driving factors (9 factors and 1 constraint) in landfill site selection were generated. Second, for the fuzzy membership function, the analytic hierarchy process (AHP) method was employed for the standardization of criteria and determining the weight of the driving factors. Then, the Boolean, weighted linear combination (WLC) and ordered weighted average (OWA) methods were utilized to spot optimal sites for landfills. Finally, two suitable sites were found for landfills: site (a) was obtained from the WLC, and site (b) was obtained from OWA-low risk some trade-off (LRST) methods. Our results proved the high efficiency of multi-criteria decision-making methodology for landfill site selection.

Abstract:
Modern landfilling constitutes an unavoidable final step in solid waste management. It aims to close the “Material Cycle” bringing elements back to the non-mobile state they were in before their extraction. At the same time, the application of Sustainability Principle to landfills prescribes to guarantee environmental protection and health safety, ensuring that the disposed waste will be chemically and biochemically stable within a reasonable amount of time. A “Sustainable Landfill” must combine these two fundamental purposes, balancing the efforts to obtain a “sustainable closure of material loop”. The enhancement of biochemical processes in a landfill, with the purpose of reaching faster environmentally safe conditions and terminate the post closure care, is one of the main debated topics in waste management scientific literature. The general aim of the PhD project was giving a contribution to this debate through the lab-scale testing of systems able to simulate landfills behaviour and the analysis of the long-term expectable chemical status of waste undergone to sustainable landfilling. The first part of the work is an overview on the basic biochemical processes in landfills and on the laboratory-scale landfill simulation tests. The approach used by the PhD student is mainly experimental, starting from the design and the management of several laboratory-scale landfill simulation tests. The elaboration of the obtained data was useful for evaluating the performances of the tested bioreactor concepts as well as for comparing the results to other scientific data derived from a thorough bibliographic research. The original work produced by the student can be subdivided in three different arguments. The Semi-aerobic, Anaerobic, Aerated (S.An.A. ®) hybrid bioreactor is an innovative landfill concept, lab-scale run with promising results concerning the enhancement of methane production and the reduction of the long-term emissions. The effects of the recirculation of reverse osmosis leachate concentrate inside the landfill have been analysed to check if the potential accumulation of contaminants in waste body can turn this practice unsustainable. The Final Storage Quality (FSQ) procedure, for endorsing the landfill Post Closure Care termination, was tested on an over-stabilized waste of which total emissions and chemical speciation of main elements were calculated.
Il moderno sistema di deposito finale dei rifiuti in discarica costituisce un passaggio inevitabile nella gestione dei rifiuti solidi. Il suo scopo è chiudere il “ciclo della materia” riportando gli elementi allo stato di immobilità in cui erano prima di essere estratti. Contemporaneamente, l’applicazione del principio di sostenibilità alle discariche prescrive di garantire la salvaguardia ambientale e della salute, assicurando che il rifiuto smaltito diventi chimicamente e bio-chimicamente stabile entro un tempo “ragionevole”. Una “Discarica Sostenibile” deve combinare questi due principi, bilanciando i contributi per ottenere una “chiusura sostenibile del ciclo della materia”. Il potenziamento dei processi biochimici in discarica, con lo scopo di raggiungere più velocemente condizioni che garantiscano la salvaguardia ambientale e terminare la fase di post-chiusura, è uno degli argomenti più dibattuti nella letteratura scientifica inerente alla gestione dei rifiuti. Lo scopo generale del progetto di dottorato è stato contribuire a questo dibattito, mediante lo svolgimento di test in scala di laboratorio utili a simulare l’andamento dei processi in discarica e analizzando lo stato biochimico finale dei rifiuti trattati. La prima parte del lavoro consiste in una panoramica sui processi biochimici in discarica e sulla metodica dei test biochimici in scala di laboratorio. L’approccio usato dallo studente in questa tesi è principalmente sperimentale, basato sulla progettazione, l’esecuzione e la rielaborazione dei dati di svariate simulazioni di discarica in laboratorio. La discussione dei risultati ottenuti è stata propedeutica alla valutazione delle performance dei modelli concettuali testati così come al confronto con altri risultati ottenuti grazie a una approfondita ricerca bibliografica. Il lavoro originale svolto dallo studente può essere diviso in tre progetti principali. Il reattore ibrido Semi-aerobico, Anaerobico, Aerato (S.An.A ®) è una concetto innovativo testato in scala di laboratorio con promettenti risultati per quanto concerne la stimolazione della produzione di metano e la riduzione delle emissioni di lungo termine. Gli effetti del ricircolo del concentrato di percolato da osmosi inversa all’interno del corpo rifiuti di una discarica sono stati analizzati per verificare se possano esistere potenziali accumuli di contaminanti che rendano insostenibile tale pratica. La procedura di Final Storage Quality (FSQ) per determinare la chiusura della fase di aftercare di una discarica è stata testata su un rifiuto sovra-stabilizzato di sui sono state calcolate emissioni totali e la speciazione chimica degli elementi principali.

Abstract:
Landfilling of municipal solid waste is a major waste disposal method, especially in developing countries despite its pressing environmental challenges. Reuse of the landfill composite has been suggested as a sustainable management option that could limit its negative effect. This research evaluated the compositional trend and characteristics of landfill composites with depth in order to assess its suitability as a precursor for activated carbon. A bulk system classification was used during analysis of the composite parameters (‘more degraded’ and ‘less degraded’ components). Both landfills had similar waste constituents, but varied in relation to moisture, TOC, and heavy metals contents. The elemental and chemical constituents of an active and a closed landfill were compared using Fourier transform - infrared (FTIR) spectroscopy, scanning electron microscope/energy-dispersive X-ray (SEM/EDX) spectroscopy, and proximate analysis. The two landfills had similar major elemental constituents representing 96.5 % and 98.4 % of elemental composition for the closed (O > C > Si> Fe > Ca >Al) and active(C > O > Si > Al > Ca > Fe) landfill samples respectively. A single step chemical activation process of precursor was applied involving irradiation with microwave energy and KOH as the activation agent. The average percentage yield of activated carbon (AC) from active landfill precursor was higher than that from closed landfill for all three depths of sampling (upper, 23.8 and 19.3 %; mid, 52.4 and 34.7 %; lower 35.7 and 27.0 %). Methylene blue adsorption capacity and BET surface analysis indicated adsorption capacity and surface area of AC from degraded precursor increased with depth. All AC conformed to a multilayer adsorption model and a pseudo second order kinetic. Carbonyl and hydroxyl groups were the major functional group on the surface of activated carbon. The AC properties indicated that precursors from both landfills are potentially suitable for generation of adsorbent suitable for removal of cationic dyes and pollutants.

Abstract:
The utilisation of a willow vegetation filter for the treatment of landfill leachate is an environmentally and economically appealing solution for landfill operators. Investigations into the design and efficacy of the system, the effects of landfill leachate irrigation on soil ecology, soil chemistry and willow growth were undertaken. Two low cost, high density polyethylene-lined experimental willow plots (25x50 m2) were installed at Cranford landfill, Northamptonshire, UK, and irrigated with landfill leachate between June 2001 and October 2005. During the growing season, leachate volume was often reduced to zero. On other occasions, maximum removal efficiencies of between 33 % and 75 % for total Kjeldahl nitrogen, chemical oxygen demand and sodium, potassium and chloride ions were determined in landfill leachate effluent samples. The addition of landfill leachate produced no negative effects on both soil and foliar macronutrients, which were found to be in the range for sufficient or optimum growth and where additional fertilisers would not bring about a further increase in yields. The effects of landfill leachate application on soil microbial communities were explored and were found to be significantly higher for dehydrogenase activity and ammonium oxidising bacteria in the plot receiving a higher rate of leachate application. An economic analysis was carried out to demonstrate the financial viability of a willow vegetation filter as a treatment for landfill leachate. Willow vegetation filters could provide a desirable alternative to conventional treatment systems, such as sequencing batch reactors, as they incur lower capital expenses and potentially similar operational costs. This study also identified additional revenue benefits in the region of £94 per hectare for wood chip heat/energy production. The results from the willow vegetation filter under investigation in this study demonstrated that this type of system can be effective, in terms of volume reduction and removal efficiency in landfill leachate, with no detrimental effect upon the trees or surrounding environment

Abstract:
Sustainable and effective treatment of landfill leachate has become one of the most important environmental problems due to the fluctuating composition and quantity, as well as its high concentrations of pollutants. High-tech solutions applied for the leachate treatment are expensive and energy consuming, and in addition they are not suitable at many landfill sites, especially those in rural areas. Hence there is need to develop novel and sustainable low-energy systems for the effective treatment of landfill leachates. Constructed wetlands (CWs) are inexpensive simple to operate and they have the potential to remove not only organic carbon and nitrogen compounds, but heavy metals. This study focussed on the design, development and experimental investigation of a novel CWs for the treatment of landfill leachate. The CWs employed dewatered ferric waterworks sludge (DFWS) as the main substrate. The overall aim of the study was to design and assess the novel configuration of the CWs, whilst also contributing to advancing the understanding of pollutant removal from the landfill leachate in the CWs, through the development of models to explain the internal processes and predict performance. The key design and operational variables investigated were: the primary media used, i.e. the DFWS, and the wetting and drying regimes. The CWs was configured as 4-stages in series which was operated for 220 days. Thereafter, an additional unit was added due to clogging and the CWs was operated for 185 days in this second period. Results and experimental observations indicate that the chemical treatment processes (adsorption and precipitation) contributed to the clogging. The DFWS used served as adsorbent for heavy metals removal in the system. Results of heavy metals, organic matter (COD), ammonia and total nitrogen removal indicate average removals of 99%, 62%, 83% and 81%, respectively in first period; and 100%, 86%, 90% and 82% in second period, with an average heavy metals loading rate 0.76 g m-2 day-1, organic loading rate 1070 g m-2 day-1, ammonia loading rate of 178 g m-2 day-1 and total nitrogen loading rate 192 g m-2 day-1. Results were supported through mathematical analysis using STELLA model for heavy metals transformation in CWs and numerical modelling using HYDRUS CW2D, which enhanced understanding of the internal processes for organic matter and nitrogen 4 removal. The result from STELLA modelling showed that up to 90% of the removal of heavy metals was through adsorption, which is highly significant. While HYDRUS CW2D results showed that the main path of nitrogen removal was through simultaneous nitrification and denitrification. Overall, results have shown that CWs design has great potential for reduction of metals and nutrients in landfill leachate. Results of this study can contribute to future CW research and design for landfill leachate treatment, through the increased understanding of long-term pollutant removal in these systems. In time, this may result in the wider application of CWs for landfill leachate treatment to better protect the environment.

Abstract:
The UK Landfill Tax was introduced by the Finance Act 1996 as an economic measure to discourage the use of landfill as a waste management option and to encourage a more sustainable approach in which less waste is produced and more waste is reused or recycled. A tax credit scheme was also introduced in order that a proportion of the money raised by the tax could be directed to Environmental Bodies to be used for approved environmental projects. The published papers submitted with this thesis evaluate the effectiveness of the operation of Landfill Tax and Landfill Tax Credit Scheme in a legal context by drawing upon a range of sources including the reviews of the Tax, data for Entrust and surveys conducted by the author. The Landfill Tax and Landfill Tax Credit Scheme is a tax law that is multi dimensional with environmental, social, economic, fiscal and political aspects. Like most law it seeks to change or control the behaviour of individuals and institutions but unlike most laws relating to taxation it had the potential for greater public acquiescence by a ‘double dividend’ by seeking to reduce landfill and encourage a more sustainable approach and also to be neutral in taxation terms by making a commensurate reduction in Employer’s Contributions to National Insurance and so reduce the tax on employment. The research finds that the Tax and Credit Scheme has good intentions in achieving a double dividend and recognises that it laid the foundations for a bottom up approach to improved waste management with public participation projects. However the research identifies and addresses a series of issues. In particular the Tax needed to be set at a substantial level to have an impact and did not itself reduce landfill. The Credit Scheme had the potential to encourage alternatives to landfill. However the Scheme’s range of approved projects and flaws in its operation meant it lacked a sufficiently strong sustainable waste management focus. The research notes that stakeholders support the Tax and Credit Scheme but recognise that it has scope for making a greater contribution to sustainable waste management particularly if additional Tax funds were allocated to strategic projects. In 2002 the Government diverted all the funds that would have been applied to ‘bottom up’ waste management projects under the Credit Scheme to centrally run ‘top down’ strategic projects, bringing to an end a key driver for sustainable waste management. The aim of the critical appraisal accompanying the papers is to outline the operation and highlight the criticisms and suggested reforms published in the papers between 1998 and 2004. In addition it suggests a way forward for the Landfill Tax credit Scheme, now called the Landfill Communities Fund to support once more support bottom up waste management projects. It also refers to key elements of the UK experience as an evidenced based guide to other countries that have already or are considering implementing similar taxes to the Landfill Tax

Abstract:
Resources are lost in dumps from the time civilization knows itself. Solid waste handling through ‘zero waste’ concept is important for disposed waste reuse/recycling. The challenge for future is landfill mining (LFM) – one of the approaches dealing with that approach. We can think of recycling of valuable components such as plastic, metals and even rare soil elements if we have the right technology. Fine fraction of waste derived from excavated, separated and screened waste is also a perspective of circular economy as this inert fraction may serve as methane degradation layer for covering the old as well as new landfills. It may reduce harmful CH4 emissions and diminish the raw material use for closure of dumping sites. The aim of this study is to give an outlook on opportunities and describe other benefits for circular economy from innovative construction technology of cover layer. Rejected material may contain up to 40–60% of dump site/landfill mass and we may have interest in: 1) estimation of fine fraction of waste as functional construction material; 2) watching environmental effects – possible leaching and emissions; 3) keeping dumpsite revitalization as the master plan idea. First studies revealed the potential of fine fraction of dumpsite material for sustainable covering layer development. This study is supported by the project No.1.1.1.2/VIAA/3/19/531 ‘Innovative technologies for stabilization of landfills – diminishing environmental impact and resources potential in frames of circular economy'.

Abstract:
Microplastics possess a significant threat to water resources as well as aquatic life and present a challenge in overall water resource management. Among a wide variety of entry routes available for microplastics from land to water bodies, municipal solid waste (MSW) landfills are suspected to be one of the important land-based sources (entry point) of microplastics affecting water quality. Few studies reported the presence of microplastic in the leachate obtained from municipal solid waste landfills corroborating that MSW landfills not only act as a sink of microplastic pollution but also act as a source. Microplastics from these leachates move to the soil system thereby affecting its quality and further migrate to aquatic systems. This movement of microplastic from leachate to aquatic system not only deteriorate the water quality but also highlights the importance of land-based sources of microplastic. In this review, we focused on the role of landfills as a pathway for microplastics to water bodies. The main aims of this review the abundance and characteristics of microplastics in landfills and discuss the role of landfill age. Polyethylene in fragmented and fibrous form remains the predominant type and shape of microplastic in leachates. The shape, size, and abundance of microplastics in leachates vary with landfill age. Landfills also provide a favorable environment for microplastic degradation thereby turning macroplastics into tiny plastic pieces. The major type of degradation is oxidative degradation. Our review confirms that MSW landfills are indeed a source of microplastic and contribute to microplastic pollution in soil and aquatic systems.

Abstract:
The evaluation of the impact of highly concentrated innovative carbon landfills reconstruction for the global climate balance improvement and environmental management on the organization of projects to reduce emissions of pollutants was carried out. The article elaborates conceptual tools for reducing environmental pollution to overcome the shortcomings of standard gas emission systems at landfills, improve global anthropogenic conditions and increase the global climate stability using integrated balanced scorecard cluster technology. Using the indicative mechanisms of SR-technology of environmental cleaning projects, the criteria for evaluating the efficiency of carbon landfills were corrected and quantitative deviations of the risk level of increasing the concentration of pollutants depending on climatic seasons were revealed. Using the author’s simulation method of criteria-based analysis, cross-cutting directions for improving the environmental conditions were proposed, reflecting optimal conditions for the polystructurality of carbon innovations elements and promising modified wind gusts reflecting the specifics of climatic conditions. As a result of the research, the methodology for a comprehensive evaluation of the feasibility and efficiency of stimulating carbon landfill models were proposed through the balanced scorecard focused on overcoming the resulting difference in pollutant emissions.

Abstract:
Soil and groundwater as the leachate may contaminate surrounding watersheds, thus different pollutants from closed dumps and landfills pose significant risks to human health and ecology. Pollution may lead to soil and water degradation however it might be diminished through sustainable dump site closure projects and processual management. Several decades of clays and clay minerals studies lead to modified clay composites concept that is one of the potential promising solutions for building the landfill covering material and serve as capping biocover layer at the same time. As humic substances are constituents of soil organic matter, pollutants can be sorbed on the surfaces of complex molecules. This kind of humic acid-clay mineral composite materials thus might become as low cost building material component - covering material. Construction of such layer are to be performed as a combination of clay-humic composites and landfill mined fine fraction of waste with small amendment of natural soil. Several hypotheses that are already proven has to be mentioned: a) Clay minerals produce composites with humic substances; 2) Clay-humic complexes reduce through sorption both organic and inorganic pollutants; 3) Low risk of toxic byproducts from landfill mined waste fine fraction can be the problem; 4) Such composites mostly would trap toxic contaminants (e.g., pharmaceuticals) found in reworked fine fraction of waste. The aim of the work is to provide alternative solution for landfill closure by giving theoretical considerations from multidisciplinary knowledge of environmental engineering, chemistry and waste management.

Abstract:
Waste disposal sites across Jordan pose serious risks to the environment and to public health if not managed safely. Municipal waste decomposing in open landfills also takes an environmental and socio-economic toll on neighbouring communities. While the Government of Jordan is planning to reduce the number of operational landfills and improve waste management services, persistent issues associated with unsustainable waste practices and their associated effects on the wellbeing of surrounding communities and the environment need to be addressed. Guaranteeing a sustainable waste management scheme for communities in Jordan should include increased consideration of the long-term effects that waste disposal sites have on neighbouring communities.
