Resumen

Introduction: Flies can transmitted disease. The final waste disposals were the breeding place of flies, especially when the final waste disposals weren`t implementation in good management. The objectives of the research were to analyze the differences between flies density in the Pakusari landfill and Ambulu landfill, Jember District, Indonesia. Method: the method was analytic with a cross-sectional design. The data were collected with observation, interview and measure the flies density. The population was all of the area kavling in the Pakusari and Ambulu landfill. The samples were total population. There were 4 active kavling in the landfill, and interview 68 head of the family which stays around the landfill how the flies disrupt their daily activity. The measurements of flies density were using fly grill, stopwatch, form the flies density. The type of flies was identification. Result and Discussion: Waste disposal management at Pakusari landfill was a controlled landfill, and Ambulu was open dumping. Both of flies density of the landfill were categorized very high. The measurement of flies density was in September 2019, whereas the Pakusari landfill using open dumping because of the equipment was broken. The highest flies density on Pakusari at kavling 2 dan 3,4 were 44,4 per 30 seconds (point 1) and 42,4 per 30 seconds (point 1). At kavling 2, 3 Ambulu landfills were 34 per 30 seconds (point 6) and 31,4 per second (point 1) There were sig difference flies density between Pakusari and Ambulu landfill (p=0,000). The most of flies were Musca Domestica(81%). The most distribution of flies were disturbed by the view, causing diarrhea, typus. Conclussion: Waste disposal landfill management should be improving with sanitary landill to control the flies density and decrease the vector-borne disease.

Resumen

In this article, the management of the MSW in Lençóis Paulista city is discussed. The ineficient public administration of the wastes and also the social awareness of a group of people who survived by using the leftover of these wastes, have made necessary the organization of an Integrated Management Plan of MSW, which was created by the Municipality in partnership with São Paulo State University (Unesp). The results were obtained with the restructuring of the Recycling and Composting Plant, the implementation of selective collection, the creation of a collector cooperative in partnership with the Disabled Association, and thus generating social inclusion, an increase in recyclable materials, as well as in the increase in the life of the landill, and the implementation of the composting process.

Resumen

Accurate projection of gas generation from landfills poses numerous difficulties. One needs to select and use an appropriate method from among several available options, and consider local and individual conditions of a landfill. These aspects are crucial for the economic management of the landfill gas in new landfills, and for assessing the impact of the gas on soil-water environment in old landfills. This paper is aimed at reviewing the research methods that can be used to assess the activity of new municipal waste landfills currently in operation, and of old, closed landfills after reclamation. Landfill activity can be assessed using different models and analysis of the produced gas. The actual data on the investigated municipal landfill showed that the landfill activity can be accurately assessed based on the quantitative determination of biogas formation using the LandGEM method, and the analysis of gas phase variability in the landfill accounting for oxygen, methane, carbon dioxide and hydrogen sulfide share/presence. Each landfill is different and calls for an individual approach or methodological modifications.

Resumen

Within the UK implementation of the European Union Landfill Directive (1999) has led to the diversion of biodegradable waste (BW) from municipal solid wastes away from landfills. It has been widely anticipated, but thus far not verified, that the diversion of BW and consequent reduction in BW reaching landfill would lead to a change in the degradation processes occurring within landfills and that this would be reflected in an altered evolution in leachate chemistry compared to pre-Directive landfills. This paper provides evidence based on leachate chemistry from two operational landfills together with calculations of the reduced BW content, that demonstrate the acetogenic phase that characterised pre-Directive landfill leachates is missing and is now more typical of methanogenic phase leachate. The paper demonstrates how data from national datasets and detailed landfill records can be used to constrain likely and upper estimates of the amount of BW going into post-Directive landfills, and the observed change in the evolution of leachate chemistry which has resulted from a decrease in BW content from typical values of BW (pre-Landfill Directive) of 22% to an inferred 12% in the case-study landfills. Data provided here add to the growing literature that estimates the amount of BW in recent post-Directive landfills which importantly allow the quantitative linkage between a decrease in landfilled BW and observed changes in leachate chemistry to be established such that future landfill operators can increase confidence in the effect of Directive implementation on landfill operational parameters.

Resumen

Introduction. Catalase is concentrated in plant tissues. It is one of the most active enzymes. This enzyme was identified in microbodies (peroxisomes) involved in the photosynthesis. Its role is to provide with oxygen the parts of plant tissues that have complicated access to oxygen. Catalase also affects the development of relations between the plant and pathogenic micromycetes. The plants lesion with toxic gases, salts, micromycetes, climatological factors, and bacteria cause an increase in the generation of active forms of oxygen. Catalase, in contrast to peroxidase, does not require a reductive substrate for activity. The higher is the catalase activity, the gas-resistance of the plants increases. Low catalase activity indicates a small adaptive capacity of plants to severe environmental conditions. The antioxidant enzymes of peroxidase and catalase can be a biochemical markers for the stress state of plants. Enzymes detection is an extremely complex analytical task, therefore during ecological monitoring not the emzymes presence is determined but the level of their activity in relation to the rate of reaction they catalyze. For environmental safety the investigation of catalase activity in landfills is extremely relevant. Purpose. The purpose of the work is to investigate the enzyme activity of catalase in the vegetation of landfils depending on the environment. Methods. Physiological, chemical methods and methods of logistic constructions are used in this paper. Results. In order to determine the counteraction of landfill plants to drought, we determined the level of starch in their body. The plants of different species growing on the surface and at the foot of the landfill, and at a distance of 300 m from the foot (control sample) were compared. Based on the research of starch content it has been established that the most drought-resistant species growing on the landfill and in surrounding area are city goosefoot, the wormwood and absinthium. Great bur and greater plantain are tended to low starch accumulation. According to the indicators of drought tolerance, the most unfavorable location for vegetation is the foot of landfills. The most important negative factor at the foot of the landfill is the drainage from the landfill and the evaporation of the filtration water. The drought tolerance of plants and catalase enzyme activity depending on their location are mutually influential. Using a correlation analysis, it was found that the level of starch in vegetation on the surface of the landfill does not affect the catalase activity of the investigated vegetation (the correlation coefficient is low and equals 0.35). It is caused by the low level of toxicants in edaphotopes and air, and as a consequence, by a low impact on biota. The results of research of catalase enzyme activity in ruderal vegetation of landfills are presented. The highest catalase activity has city goosefoot. The lowest catalase activity has a great bur and greater plantain. The most unfavorable for vegetation development is the foot of landfill. It has been established that the catalase activity depends on the content of starch in rhizomes. The higher is the level of starch, the more the plant counteracts the hazardous factors of landfills. Conclusions. During investigation of the catalase enzyme activity of ruderal vegetation in different areas of landfills, it was established that its level depends on the content of starch in rhizomes. The higher the level of starch, the more the plant counteracts the deleterious factors of landfills (drought, combustion products, micromycetes activity, toxic gases of wastes breakdown, activity of pathogenic microorganisms). The results of investigation of the catalase activity of vegetation in landfills can be used in planning the biological phase of reclamation and phytomelioration of landfills.

Resumen

Landfills pose an important public health risk, especially in historically disenfranchised communities that are disproportionately sited for landfills and in rural areas where private wells may be impacted. Landfills are major sources of perfluoroalkyl substances (PFAS) that migrate into the surrounding environment. This study characterized PFAS in surface waters adjacent to two landfills, one in Sampson County (SC) and one in Orange County (OC) in North Carolina. In addition to municipal solid waste and construction and demolition waste, the landfill in SC accepts industrial sludge from a chemical plant that produces proprietary PFAS. Over four months, 35 surface water samples were collected at upstream, landfill-adjacent, and downstream/downgradient sites. Thirty-four PFAS were analyzed using liquid chromatography with tandem mass spectroscopy. Of those, six novel and six legacy PFAS were detected. Legacy PFAS were detected in surface water near both landfills, with the highest concentrations adjacent to the landfill. Novel PFAS were only detected in surface water near the SC landfill and showed the highest concentrations adjacent to the landfill, indicating offsite migration of PFAS. These findings support the need for more comprehensive and frequent monitoring of groundwater and surface water wells near landfills and stricter regulation regarding the landfilling of industrial materials.

The research aims to develop a sustainable waste management strategy with qualitative descriptive method. Data collection was done through documentation, focused group discussion, interviews, and observations on the process of waste management. Waste management was seen technically from the operational, institutional, regulatory, funding, community participation aspects with reference to the theory and analysis of Strength, Weaknesses, Opportunity, and Threat (SWOT). Waste management inMojokerto Cityuses the collection, transportation, and disposal system leading to uncontrolled waste generation at the landfill as well as high operational cost. Trials on waste reduction in terms of sources as well as waste management at the regional level were done, yet they had not provided optimum result as waste disposed at the landfill amounting to 273 m3 per day. Waste management in the landfill with landfill control systems and solid waste generation rate of 1.6% per year lead to failure in cost recovery.Developing waste management strategy to reduce the volume of waste sources by involving the active participation of domestic and community scale or regional groups, improving the quality of the management of the landfill as a processing site instead of disposal, increasing waste services coverage, increasing cooperation with individuals, developing the system of rewards and sanctions, recovering costs of waste management, regional cooperation in waste management, optimizing the utilization of solid waste infrastructure are all necessary.

Resumen

One of the most acute environmental problems of our time is the problem of handling solid municipal waste (SMW). Landfills are significant sources of environmental impact, the main factors of which are the release of landfill gases and landfill filtrate. The purpose of the article is to identify “white spots” in the issues of the study of landfill filtrate at Russian landfills and to pose topical research questions. A review of studies on the volume and composition of landfill filtrate, methods for studying its effects on the components of the natural environment was completed. In order to assess the impact on the composition of waste and the filtrate formed during their placement at SMW landfills, modern trends in the handling of SMW are considered: an increase in the share of electronic garbage and plastic in the composition of waste. The volume of landfill filtrate formation at SMW landfills is estimated using the example of the Tyumen region. It has been established that landfill filtrate has a different composition depending on the stage of the landfill life cycle and poses a real environmental hazard. The data of various researchers on the concentrations of pollutants in landfill filtrate are poorly comparable, since the filtrate at each landfill has its own distinctive features due to the specifics of the arrangement and operation of the landfill, as well as the specifics of its location. Under these conditions, the prospects for research on the impact of landfill filtrate on the natural environment are primarily associated with the study of the impact of each specific landfill, as well as with the development of models that adequately reflect the basic patterns of landfill filtrate formation in different conditions.

Resumen

Recent studies have addressed several constraints to ensure the effective applicability of numerous models. However, an exclusive model meant for landfill utilisation for landfill facilities is still untapped. As such, this paper proposes a new constraint faced by landfill facilities to ensure a more comprehensive model and its applicability to real-life issues. This idea is influenced by three main reasons. First, the lifespan of selected landfills is bound to decrease due to the increasing density of waste transported to landfills daily. The second reason is abandoning the available landfill sites due to inappropriate locations. Lastly, the government would need to bear high costs in establishing more landfills to accommodate the annually increasing waste. Hence, the Nearest Greedy method was applied to a benchmark problem of Waste Collection Vehicle Routing Problem (WCVRP) to construct feasible initial routes by considering the following three scenarios of landfills: (1) without capacity priority, (2) balance capacity priority, and (3) imbalance capacity priority. This study highlights the importance of using all available landfills to unload waste for the WCVRP. Weighing in this additional constraint may increase the life expectancy of the available landfill sites. However, the computational findings revealed that utilising all available landfill facilities (scenarios 2 and 3) can significantly increase the total distance travelled and the number of vehicles used compared to Scenario 1.

Resumen

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.

Resumen

"Transparency- the ability to see into and understand the inner workings of a landscape- is an absolutely essential ingredient to sustainability" -Robert Thayer from "Green World, Green Heart" Current land filling practices that bury waste and debris below layers of earth and synthetic caps do not take into account the potential of reclamation of the site after the landfill debris has become stable. As development and consumerism increases, the need for land reclamation grows stronger, as earth will succumb to overabundance of human excessiveness. Can a space be created that not only reclaims land, but also exposes what is hidden- in order to educate the public on the importance of recycling and sustainability? Is it possible to design a space that addresses the issues and culture of the past, present and future, particular to a geographic site? Can landscape architects use landscape as an educational medium for self-discovery?

Resumen

Deux thématiques principales ont été développées dans cette thèse : l’optimisation de la mise en place des déchets pour un meilleur démarrage de la biodégradation et l’optimisation de l’injection de lixiviats. Pour cela, deux zones expérimentales en conditions de stockage réelles ont été instrumentées ; la modélisation et des expériences en laboratoire ont également contribué à la compréhension des phénomènes en jeu. Concernant l’optimisation de la mise en place des déchets, neuf mini-casiers de 1700 m3 ont été remplis selon des modalités de broyage, compactage et d’épaisseur de couches différentes. L’instrumentation mise en place a permis de suivre qualitativement le démarrage de la méthanogenèse, et notamment de distinguer certaines phases du processus de biodégradation et d’évaluer l’impact relatif des différentes modalités de placement. Ainsi, les trois modalités testées semblent intéressantes pour améliorer les conditions de stockage du déchet. Un suivi sur le plus long terme permettrait de confirmer ces tendances. L’étude d’optimisation de la recirculation a été réalisée à l’échelle d’un casier d’ISDND. Le système d’injection testé est un réseau de bassins drainant enterrés. L’instrumentation mise en place ainsi qu’une modélisation des écoulements, ont permis d’en évaluer le fonctionnement. Alors que le type de matériau drainant utilisé n’influence pas les performances de ces systèmes, les propriétés du déchet directement sous-jacent semblent régir les écoulements. Une diminution des performances au fur et à mesure des injections met en évidence un potentiel colmatage des systèmes ou une diminution de la perméabilité du déchet sous-jacent
Two ways of optimizing waste biodegradation in a bioreactor landfill have been studied: how to set-up the waste so that the kinetic of biodegradation is increased, and how to inject leachate. To achieve this, two full-scale experimental areas have been instrumented; modelling and laboratory work enable to better understand the occurring phenomena. To study the impact of waste placement, nine test cells of 1700 m3 were filled with different procedures (compaction, shredding and lift thickness). The instrumentation allowed to follow qualitatively the onset of methanogenesis, and to distinguish some steps of the biodegradation process consequently to determine the relative influence of the different placement procedures. The three tested procedures appeared to be interesting on the short term. Follow up of the project on a longer term will enable to check this tendency. The study regarding waste injection optimization has been realized on a full-scale landfill cell. The injection system implemented is a network of buried injection pads, filled with a drainage material. Whereas the type of filling material does not influence the injection system performances, underlying waste properties seem to rule leachate fluxes. A reduction of the performances with repeated injections unlighted a potential clogging of the injection systems or a decrease of the underlying waste permeability

Increased waste generation and poor waste disposal strategies are a global problem. In South Africa most provinces, and the larger municipalities and metros, seems to have the waste disposal and the landfills reasonably organized. This cannot be said of the landfills in the Free State Province, which could only be called dump sites. In the Free State Province a high unemployment level exists and a lack of finances is experienced by many members of the communities, especially in rural areas. Poverty levels is shown in a study by Adventist Development and Relief Agency (ADRA SA), where it was recorded that 1.8 million (68%) of the people in the Free State Province are living in poverty and living on less than R15 per day. Data on the state of the landfill, types of waste generated which have potential to be recycled, were recorded to assess if recycling could be increased to relieve the economic burden of the poor communities. Attention was paid to the following aspects: assessing the current status of each landfill and identifying the types of waste generated in the area which ended up at the landfills. The extent of recycling and the waste handling and disposal of the waste were recorded. Non-compliance with the prescribed legislative guidelines were noted and aspects such as the state of the landfills, proper enclosure, burning of waste, recycling and products being recycled were identified and recorded. The waste disposal practices at most landfills were poor and very limited recycling was taking place. None of the landfills in the province complied with the minimum requirements for landfilling. Recommendations to improve waste disposal and identification of products with recycling potential were made. Alternative waste strategies which could be economically beneficial for the communities were recommended

Resumen

The area immediately surrounding a landfill was studied by DC resistivity methods, soil borings, and review of historical data bases to learn if the landfill had released leachate to the ground water and to define the geology and hydrogeology of the site. Property immediately adjacent to the landfill has been proposed as a new landfill site. The geology and hydrogeology of this site were investigated to provide supplemental data for use in planning and operating the new landfill.Although no contaminant plumes were located by resistivity methods, the range in measured resistivity values proved to be sufficiently large to possibly mask existing leachate migration from the landfill. Using the resistivity data base generated through this effort, future resistivity surveys at this site may identify changes indicating contaminant plume formation or migration.Zones of shallow sand and gravel were found (by resistivity methods) to be present at locations that appear to correlate with slightly higher topography and soil type MuB2. This information led to the location and confirmation of other shallow permeable zones in the glacial drift with the same common attributes (soil type MuB2, higher topography and 5 to 15 feet deep sand and gravel). These shallow permeable zones had been omitted from the ground-water monitoring systems for both the Metropolitan Landfill and the proposed Delaware County Landfill. The results of this study were used as the basis for recommendations presented to the local board of health and the state regarding the need for additional ground-water monitoring at the two sites and the suggested locations for such.

Resumen

All processes in society produce waste. In nature, the waste is normally used as a resource for another process, but in human societies waste is often discarded. These discarded materials end up in places for depositing waste known as landfills. The increase in population, and humans’ tendency to improve their quality of life, has led to an increase in consumption of material. More material consumption means generating more waste, and more waste means bigger landfills. The increasing size of landfills has brought some other issues, such as increased land use and higher environmental impact. However in these landfills a lot of valuable materials are discarded and the concept of landfill mining (LFM) has been proposed in order to solve these issues and use landfills as a possible source of materials. Landfill mining is not yet a common practice, and the first barrier for this is the uncertainty of the amount and value of materials within landfills. The purpose of this study is to prospect the amount of metals in one specific landfill, in this case Gärstad landfill in Linköping, Sweden. This is a first step to show the feasibility of landfill mining as an alternative way of extracting materials. The study is limited only to metals because they are one of the most important resources in today’s society. The theoretical background of the study is based on material flow analysis (MFA). Two approaches are used to study the materials in the landfill. The first is top-down which studies the flows of materials and the second is bottom-up which studies the stocks of material in the landfill. Based on these approaches the method was developed. First the system boundaries in time and space were defined. Then the amount of waste in landfill was estimated from the two mentioned approaches. In the end the metal content of the waste was estimated. Some criteria are also defined to compare the accessibility of the metals in the landfill. The results of this study show that there is a considerable amount of metals in the landfill, and that ash deposits resulting from incineration are the most interesting source of metals; with iron, aluminium, copper and zinc being the most abundant. The results are presented by type of waste, area of the landfill and accessibility in order to identify the hotspots. Later it is discussed that the method is cheap and fast but highly depends on previous data and available information. Also the metal content of the landfill is compared with natural ores. In the end the metal content of the landfill is evaluated and estimated to be around 3 billion SEK. It shows that aluminium, titanium and copper have the highest value money wise. As conclusion it was shown material flow analysis is a valid way to prospect landfills. But further cost-benefit analysis must be carried out to determine if landfill mining is justifiable. Also some recommendations are proposed to Tekniska Verken in order to facilitate future studies. The first is to develop a systematic way for landfilling different kind of waste and document them. Second is to include metals which have economic potential in the regular sampling from landfill.
Många processer i samhället generar avfall. I naturen används avfallet normalt som en resurs i en annan process, men i människliga samhällen kastas avfallet oftast bort. Bortkastat material hamnar förr eller senare oftast i deponier. Befolkningsökningen och människans tendens till att försöka förbättra sin livskvalitet har lett till en ökad materialkonsumtion. Högre konsumtion genererar mer avfall, och mer avfall kräver större deponier. Växande avfallsanläggningar leder i sin tur till ökad markanvändning och högre miljöpåverkan. I dessa anläggningar finns det emellertid stora mängder värdefullt material deponerat, och från dessa läcker både tungmetaller och metan ut, vilket är skadligt för miljön. Landfill Mining (LFM) har föreslagits som en lösning på dessa problem och avfallsanläggningarna används då även som en möjlig källa till material. Landfill mining är idag inte vanligt förekommande och det huvudsakliga hindret är de många osäkerheterna kring ett sådant projekt, till exempel; hur mycket material finns i deponierna och hur mycket är det värt? Syftet med den här studien är att uppskatta metallinnehållet i en specifik avfallsanläggning, i det här fallet Gärstad avfallsanläggning i Linköping. Detta är ett första steg i att utröna genomförbarheten av LFM som en alternativ resursbas. Studien är begränsad till metaller eftersom dessa håller på att ta slut i jordskorpan och det vore därför intressant att finna nya materialkällor till dessa. Den teoretiska bakgrunden till den här studien är baserad på materialflödesanalys (MFA). Två metoder har använts för att prospektera Gärstad. Dels top-down, som studerar flödet av material, dels bottom-up, som studerar materialförrådet i avfallsanläggningen. Avfallens totalmängd var uppskattad genom att beräkna flödet in och ut från anläggningen. Sedan använde vi tidigare gjorda provtagningar av avfallets metallmängder för att uppskatta metallinnehållet. Slutligen analyserades metallernas tillgänglighet baserad på typ av avfall, och om deponi delområdet var sluttäckt. Resultatet visar att det finns mycket metaller deponerat i Gärstad. Askan från avfallsförbränningen visade sig vara den avfallstyp med rikast metallinnehåll. Järn, aluminium, koppar och zink är de vanligaste förkommande metallerna. Metallkoncentrationen av avfallsanläggningen kan jämföras med naturliga malmer. Värdet av metallerna i Gärstad uppgår till cirka 3 miljarder. Dock är endast 30 % av metallerna tillgängliga med dagens teknik. De största värdena finns enligt följd i aluminium, titan och koppar. För att identifiera hotspots, redovisas resultatet enligt avfallstyp, lokalisering och tillgänglighet. MFA är ett fungerande prospekteringsverktyg för deponier. Metod är billig och snabb men beroende av att det finns tillgänglig data. Innan deponin transformeras till en gruva bör emellertid först en kostnad och nyttoanalys genomföras för att undersöka genomförbarheten vidare. Rekommendationer för att underlätta framtida utgrävningar är att utveckla ett systematiskt sätt att deponera olika typer av avfall och att dokumentera dem. De metaller som har ekonomisk potential bör dessutom inkluderas vid den normala provtagningen av deponerat avfall.

Resumen

This essay uses the modern landfill, a hyper-object that the anthropologist Joshua Reno terms the “constitutive absence” of modernity,” to explore the gaps, lacunae, and interstices of a waning era of fossil fuel dominance. In examining the landfill as something akin to the repressed ID of fossil capitalism, it brings into the exposure of the sun both the dark ideological recesses of liberalism and the literal material processes of late capitalism that work to systematically bury the material detritus and human wastage they produce out of sight. An intentional experiment in breaking the strictures of academic expository form, this essay also strives to reoccupy, at least momentarily, the symbolic spaces left behind by the internal contradictions of this decadent version of fossil capitalism we live amidst today. It takes that opportunity to imagine, at least in passing, what it might mean to reinhabit liberalism’s symbolic terrain by reorienting ourselves to a more sustainable alliance with nature centered on the sun and keyed more closely to a solidarity with others that might help us escape the wastefulness and destructive linearity of a transactional consumer culture that drives us further into global warming.

Resumen

The storage yard’s leak-proof protection should be achieved by means of independent protective barriers in the form of geological barriers, artificial sealing layers, mineral soil liners and covers, as well as sidewall sealing. Some years ago, construction and exploitation of landfill sites in Poland took place without any guidelines and legal regulations. Landfills, especially situated in rural areas, were quite often constructed directly on the grounds, e.g. in former aggregate excavations, without any protection. Examples of the municipal landfills, located in the sites of adverse geological conditions were presented in this paper. The effect of existence or absence of geological barriers on the groundwater quality was carried out. In tested landfills, higher concentrations of groundwater pollution indicators were found in landfill monitoring wells located on the outlet of these waters, in comparison to the landfill monitoring wells located on their supply. In the case of the landfills situated directly on the soils of high hydraulic conductivity, the indicators of negative influence of deposited landfills increased even after the closing of the landfill sites. Subsurface water-bearing layer is a kind of “indicator” giving information about the harmful effect of landfills on the environment, and the need to take remedial actions.

Resumen

Landfills are one of the most common ways to dispose the solid urban waste in many countries due to their relatively simple technical requirements, operational costs and low investment. Moreover, biogas produced in landfills can be used as a renewable energy source for power generation. The Valencian Region is one of the largest solid urban waste producers in Spain, and therefore, it has an unexplored potential of landfill biogas production. This paper aims to estimate the potential of biogas landfill production for power generation in the Valencian Region. Statistical data from solid urban waste in landfills in the provinces of Alicante, Castellón, and Valencia was gathered. Then the potential of landfill biogas production was estimated by means of waste classification for each province. To provide information related to the use of landfill gas as an alternative source of energy, results presented in this work show that the Valencian Region has an important potential to use landfill biogas from solid urban waste as a renewable source for power generation, and also provide information to the regional government, academic researches, policy makers and investors.

Resumen

Landfill gas (LFG) recovery predictions obtained using Mexico Landfill Gas Model 2.0 were compared to LFG recovery rates from the two biggest landfills in Mexico (Mexico City Landfill called “Bordo Poniente” and Monterrey City Landfill “SIMEPRODE”.). The corresponding landfill characteristics (e.g. leachate levels and handling; use of covers and/or liners, compaction procedures, etc.) where analyzed and considered for the modeling in both cases, resulting in recovery efficiency rates and correction factors for each site. For Mexico City landfill, a pumping test was performed for a period of 25 days during a bidding process, started by Mexico City Government. 11 extraction wells were installed for the test along with a blower-flare system, with a capacity of 1,000 m3/hr. During the test period, individual well measurements were taken every 4 hours obtaining information such as: gas composition (CH4, CO2 and O2), vacuum pressure and gas temperature. Also a main measurement was taken every 4 hours at the blower-flare system in which obtained the total LFG flow in addition to the above information. Modeling results for Mexico City landfill show a good accuracy (below the actual recovery rate obtained during the test). For Monterrey City landfill, the recovery rates were obtained from the historical data from the LFG to energy (LFGTE) project running since 2003 by BENLESA. Only the information between 2009 and 2012 were considered due to the last expansion of the plant to 16 generators, 1.06 MW each. Modeling results for Monterrey City landfill, overestimated the actual LFG recovery for the last 4 years including 2012. The causes for the difference between modeled and actual recovery rates for both landfills were analyzed and recommendations to improve the modeling results and the recovery rates were made.

Resumen

In the 1980’s, California faced landfill siting problems and a projected shortage of landfill capacity that could impact the health and safety in California. To address this issue, the California Integrated Waste Management Act was passed in 1990 and established a framework to limit reliance on landfills. This framework gives greater emphasis to recycling, waste prevention, source reduction, and composting. The Integrated Waste Management Act required each city and county to implement plans to divert 25% of solid waste by 1995 and 50% by 2000 from landfills. Although we have achieved a 47% diversion rate and have 170 composting facilities, we still have approximately 30 millions tons of material being landfilled. This may be an untapped resource for energy and alternative fuels production.

Resumen

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.

Resumen

The U.S. generates about 370 million short tons of Municipal Solid Waste (MSW) each year. In 2002, an average of 26.9% of this material was either recycled or composted. Of the remainder, an estimated 242 million short tons were disposed of in landfills and about 29 million short tons were combusted in Waste to Energy (WTE) facilities to produce electricity and scrap metal. Effective management of MSW is becoming increasingly challenging, especially in densely populated regions, such as New York City, where there is little or no landfill capacity and the tipping fees have doubled and tripled in recent years. There is also a growing appreciation of the environmental implications of landfills. Even with modern landfill construction, impacts remain from the need for transfer stations to handle putrescible wastes, their transport to distant landfills, and finally landfill gas emissions and potential aqueous run-off. Environmental impacts of concern associated with disposal in WTEs include air emissions of metals, dioxins and greenhouse gases. In the U.S., there is also a strong negative public perception of WTE facilities. Decisions about waste management should be influenced by a consideration of the overall, quantified life-cycle environmental impacts of different options. In this paper we therefore develop a methodology to assess these impacts for landfilling and WTE waste management options. Specifically we attempt to compare these two options for New York City, a large urban area.

Resumen

The management of municipal solid wastes (MSW) in Puerto Rico is becoming increasingly challenging. In recent years, several of the older landfills have closed due to lack of compliance with federal landfill requirements. Puerto Rico is an island community and there is limited space for construction of new landfills. Furthermore, Puerto Rico residents generate more waste per capita than people living on the continental US. Thermal treatment, or waste to energy (WTE) technologies are therefore a promising option for MSW management. It is critical to consider environmental impacts when making decisions related to MSW management. In this paper we quantify and compare the environmental implications of thermal treatment of MSW with modern landfilling for Puerto Rico from a life cycle perspective. The Caguas municipality is currently considering developing a thermal treatment plant. We compare this to an expansion of a landfill site in the Humacao municipality, which currently receives waste from Caguas. The scope of our analysis includes a broad suite of activities associated with management of MSW. We include: (i) the transportation of MSW; (ii) the impacts of managing waste (e.g., landfill gas emissions and potential aqueous run-off with landfills; air emissions of metals, dioxins and greenhouse gases) and (iii) the implications of energy and materials offsets from the waste management process (e.g., conversion of landfill gas to electricity, electricity produced in thermal treatment, and materials recovered from thermal treatment ash). We developed life cycle inventory models for different waste management processes, incorporating information from a wide range of sources — including peer reviewed life cycle inventory databases, the body of literature on environmental impact of waste management, and site-specific factors for Puerto Rico (e.g. waste composition, rainfall patterns, electricity mix). We managed uncertainty in data and models by constructing different scenarios for both technologies based on realistic ranges of emission factors. The results show that thermal treatment of the unrecyclable part of the waste stream is the preferred option for waste management when compared to modern landfilling. Furthermore, Eco-indicator 99 method is used to investigate the human health, ecosystem quality and resource use impact categories.

Resumen

An economic and technical analysis of the use of separated wood biomass as a feedstock for gasification for a 3 MW power plant was conducted for the Miramar Landfill, located in San Diego County, CA. The method to generate combustible gas from the biomass is based on a dual-fluidized bed gasification process which operates at atmospheric pressure with air and produces a high quality producer gas with little nitrogen. The objective of the study was to determine the economic feasibility of the proposed biomass power system in terms of the potential revenue streams and costs. Major economic considerations in the analysis include feedstock, capital, and operating costs. Regulatory issues, inclusive of production credits, renewable energy incentives, and feed-in tariffs are addressed as significant economic inputs. The Miramar landfill, in San Diego County, CA is representative of a typical existing urban landfill, with corresponding feedstock and some market for separated wood biomass. The economic analysis of the proposed 3MW gasification power plant indicates that it would not have a net positive NPV under the current urban scenario. More likely successful candidates are landfill sites in more rural areas or urban sites, where new landfills are being developed or where the landfill is no longer operational but has become a transfer station. In all cases waste heat sales are a critical element in determining economic viability.

Resumen

Finite and decreasing landfill space on Army installations is a significant concern. Efficient waste management is essential for achieving resiliency and extending the lifespan of remaining landfills. The purpose of this demonstration was to conduct independent performance tests of small unmanned aircraft systems (sUAS) and their utility for providing landfill assessments in remote areas where physical presence is either dangerous or inefficient. An active, near capacity construction and demolition (C&D) landfill at Fort Gordon, Georgia, was identified for the demonstration. The flights, data requirements, and outputs generated by the sUAS flyovers were analyzed for efficacy in detecting cell capacity and subsidence. Each flight took 1–2 hours for mobilization, ground marker placement, flight, and postflight analysis. Volumetric and topographic surveys were analyzed in less time than is typical for traditional surveying methods. After initial setup of ground markers and rectification, sUAS flights save a significant amount of time. However, skilled individuals are required for flights and for processing and maintaining data. The technology is widely relevant to the Army, is commercially available, and offers an average of 30% cost savings in terms of manpower, repeatability, and equipment. The use of sUAS technology is recommended for monitoring and surveying Army landfills.
