With the rapid and large increase of waste quantities, China, surpassed the USA as the worlds largest municipal solid waste (MSW) generator since 2004. The phenomena and critical issues of MSWM in China inspired this paper to investigate and analyse the MSWM in an urban area of China. Comparing with the increasing rates of MSW generation, little has been done concerning the municipal solid waste management (MSWM). Not only the local government and authorities are responsible for the MSWM, but also the individuals are playing a significant role in MSWM. An integrated waste management system should be built in order to improve the holistic MSW system and reduce the waste production. The aim of the study is to investigate and analyse the current status and problems of MSWM in an urban area of China and to analyse to what extent a viable reduction of the MSW can be implemented and management systems to be improved in the near future. In this study, two case studies of Shanghai and Linköping are ...
Previous studies have raised concerns about possible excess risks of bladder, brain and hepatobiliary cancers and leukaemias near landfill sites. Several cancers have been implicated, but no consistent pattern has emerged. We present a large nationwide analysis of selected cancers near landfill sites in Great Britain. The base population comprised people living within 2 km of 9565 (from a total of 19196) landfill sites that were operational at some time from 1982 to 1997, with populations living more than 2 km from a landfill as reference. Risks of cancers at the above sites were computed with adjustment for age, sex, year of diagnosis, region and deprivation. National post-coded registers provided a total of 341856640 person-years for the adult cancer analyses and 113631443 person-years for childhood leukaemia. There were 89786 cases of bladder cancer, 36802 cases of brain cancer, 21773 cases of hepatobiliary cancer, 37812 cases of adult leukaemia and 3973 cases of childhood leukaemia. In spite ...

The significant generation of municipal solid waste (MSW) has become a controversial global issue. Pyrolysis and gasification technologies for treating rejects from solid waste disposal sites (SWDSs), for which over 50 % of MSW is attributed to combustible species, have attracted considerable attention. MSW is an alternative energy source that can partly replace fossil resources; there is an increasing awareness that global warming caused by the utilization of fossil resources is occurring.. The goal of this thesis is to realize the efficient and rational utilization of MSW and decrease the harmful impact of pollutants, such as dioxin, HCl, and CO2, on the environment. To achieve this goal, some fundamental studies have been experimentally and numerically conducted to enhance the understanding of the properties of municipal solid waste thermal conversion.. In this thesis, the pyrolysis behaviors of single pelletized recovered fuel were tested. A detailed comparison of the pyrolysis behaviors of ...
Atmospheric pollution is of a major public health concern in many large cities worldwide. However, in many cases only a little attention has been given to this issue in developing countries. Example is the case of Alexandria city in Egypt where two municipal solid waste (MSW) dumpsites were located at the east and west directions of the city. One of the main activities leading to this problem includes deposition of compost and incineration of MSW, which contain high levels of heavy metals. Such activities tend to increase the elemental background levels in the surrounding agricultural land driving to adverse temporal and/or spatial variations of heavy metals levels in soils.. Atmospheric deposition of anthropogenic derived chemicals is an important source of environmental pollution. It contributes to the load of pollutants in urban runoff [1, 2].. Municipal Solid Waste management depends on the characteristic of the solid waste including the gross composition, moisture contents, average particle ...
Highlights: ► The isotopic signature of δ{sup 13}C-DIC of leachates is linked to the reactivity of MSW. ► Isotopic signatures of leachates depend on aerobic/anaerobic conditions in landfills. ► In situ aeration of landfills can be monitored by isotope analysis in leachate. ► The isotopic analysis of leachates can be used for assessing the stability of MSW. ► δ{sup 13}C-DIC of leachates helps to define the duration of landfill aftercare. - Abstract: Stable isotopic signatures of landfill leachates are influenced by processes within municipal solid waste (MSW) landfills mainly depending on the aerobic/anaerobic phase of the landfill. We investigated the isotopic signatures of δ{sup 13}C, δ{sup 2}H and δ{sup 18}O of different leachates from lab-scale experiments, lysimeter experiments and a landfill under in situ aeration. In the laboratory, columns filled with MSW of different age and reactivity were percolated under aerobic and anaerobic conditions. In landfill simulation reactors, ...
Incorporation of waste materials, in this case, municipal solid waste (MSW) and marble residue rich in calcium carbonate in the production of traditional ceramics could give rise to industrial cost savings. At the same time, the utilization and recycling of wastes as a secondary raw material can help solve environmental problems associated with the wastes. In this study, ceramic tile bodies were obtained by adding recycled municipal solid wastes (MSW) and marble residues to standard clay samples. Water absorption capacity and bending strength were measured to evaluate the properties of the resulting ceramic materials. Water absorption increases with an increase in the residue percentage. Addition of waste residues to ceramics also gives rise to a decrease in bending strength. Use of residues in the manufacture of bricks and roofing tiles affects the final properties of these products. The most suitable products were selected based on technological and ceramic behaviour. With respect to the ...

Knowledge on the pharmaceuticals and personal care products (PPCPs) in landfill leachates, which are an important source of PPCPs in the environment, was very limited. Hence, four sampling campaigns were conducted to determine eighteen PPCPs in the landfill leachates from a landfill reservoir in Shanghai. Five of the target PPCPs were first included in a landfill leachate study. Additionally, their removal from landfill leachates by a full-scale membrane bioreactor (MBR) was illustrated. The results showed fourteen out of eighteen PPCPs were detectable in at least one sampling campaign and achieved individual concentrations ranging from 0.39 to 349μg/L in the landfill leachates. Some PPCPs exhibited higher contamination levels than those reported in other countries. Good removal of PPCPs by MBR led to a largely reduced contamination level (|LOQ to 10.6μg/L) in the treated landfill leachates, which was, however, still much higher than those in municipal wastewaters in Shanghai. To the best of our

Information about Cd distribution inside single municipal solid waste and biomass fly ash particles is fundamental since it affects its leachability. The internal 2D distributions of the main and trace elements in such highly inhomogeneous matrixes were successfully determined by means of the combined synchrotron radiation induced micro X-ray fluorescence (mu-SRXRF) and tomography (mu-SRXRFT) techniques. Scanning mu-SRXRF measurements show Cd elemental distribution within single fly ash particles to be inhomogeneous, but no information can be obtained about its internal distribution. During mu-SRXRFT analysis, single fly ash particles are successively measured by a rotational-translational scan in a VH = 2 x 5 mum(2) microbeam. The 2D internal elemental distribution images, obtained by the modified simultaneous algebraic reconstruction technique algorithm, provide the size and the location of Cd-containing areas together with the location of other measurable elements. Results showed Cd concentration to

A transfer station in waste terminology is a location that facilitates the transport of refuse (trash disposed of in the black bins). Our transfer station serves to temporarily store refuse collected throughout the City before a larger truck is ready to pick it up and transport it for the long haul to the nearest landfill. As the Citys own landfills are all closed, the destinations are private landfills. In 2004, the City of Los Angeles purchased Central L.A. Recycling & Transfer Station (CLARTS). As the recycling operations that were previously done at the facility have ceased, the City continues to operate the facility as a transfer station.

B. Industrial Solid Waste. Industrial solid waste - the non-toxic or non-hazardous waste generated by various industries is normally not identified as different from municipal solid waste coming from domestic and commercial activities. In many ASEAN countries, it has been included as part of municipal solid waste. As a result, there is an absence of a systematic database on industrial solid waste and the exact rates of industrial waste generation are not known. The lack of information on industrial solid waste is lamentable because it can actually include a wide range of materials that may have different levels of impact on the environment.. The types of industrial solid waste would include packaging materials, paper, housekeeping wastes, food wastes, scrap materials such as glass and ceramics, resins, plastics, metal and plastic scraps, stones, cloth, rubber, straw, wood waste, products which are off-specification and a variety of materials not officially specified as or are known to be ...

According to the latest EPA data, Americans generated about 250 million tons of trash in 2011 and recycled and composted almost 87 million tons of this material, equivalent to a 34.7 percent recycling rate. Municipal solid waste does not include industrial, hazardous, or construction waste. It is things that we commonly use and then throw away such as packaging, food waste, computers, and furniture. Hazardous has any of the four characteristics: ignitability, corrosivity, reactivity, or toxicity.. Organic materials comprise the largest percent of municipal solid waste. Paper and paperboard are next at 28 percent and yard trimmings and food waste accounts for another 28 percent.. The Resource Conservation and Recovery Act (RCRA) set forth a framework for the management of non-hazardous wastes, as well as giving the Environmental Protection Agency (EPA) the authority to control hazardous waste from the cradle-to-grave, which includes the generation, transportation, treatment, storage, and ...
TY - JOUR. T1 - Effects of inorganic anions on Fenton oxidation of organic species in landfill leachate. AU - Deng, Yang. AU - Rosario-Muniz, Edualberto. AU - Ma, Xingmao. PY - 2012/1/1. Y1 - 2012/1/1. N2 - Fenton oxidation typically achieves only a moderate removal efficiency of chemical oxidation demand (COD) in treatment of a landfill leachate, incomparable to some other chemical oxidation processes (e.g. electrochemical oxidation). A traditional viewpoint is that the remaining highly oxidized organic species become recalcitrant to hydroxyl radical (OH·)-induced oxidation at a higher degree of Fenton oxidation. Although this may, at least partially, be true, the effects of inorganic anions, which are abundant in leachate, on Fenton oxidation have been largely ignored. The objective of this study is to assess the roles of three inorganic anions (nitrate, sulfate, and chloride) originally present in or externally added to leachate during Fenton oxidation of refractory organic species in ...

Waste disposal simply means removing and destroying or storing damaged, used or other unwanted domestic, agricultural or industrial products and substances. Disposal includes burning, burial at landfill sites or at sea, and recycling, while improper waste disposal re disposal of refuse without proper supervision which often amounts damage to the environment and ultimately to the human body system The environmentalists expressed their serious concern over the unscientific and improper management of municipal solid waste, describing it as hazardous to human health. Improper disposal of hazardous waste causes adverse effects on human health and the environment. The normal practices of waste disposal such as insanitary open dump, land filling, discharge in water courses, or open-pit burning will need modification when dealing with hazardous wastes. The principle hazard of improper waste disposal is contamination of soil and groundwater. This arises largely from the waste containing hazardous ...
With more trash coming into Keystone Sanitary Landfill in Dunmore, dangerous air emissions are on the rise, a Sunday Times analysis of state records found. The review also found the state Department of Environmental Protection relies upon the landfills to monitor air quality and report problems.. Documents submitted by landfill officials to DEP in 2010 clearly show a steady upward trend in the release of toxic gases associated with short and long-term health problems from just 0.2 tons per year in 1972 to 37.8 tons per year - 186 times more - in 2011. By comparison, a coal-fired power plant emits about 50 tons of mercury into the atmosphere annually.. These so-called volatile organic compounds can come from cleaning supplies, copy paper, glues, pesticides, permanent markers, office equipment and an assortment of other materials deposited in the landfill.. Specifically, the air pollution includes:. - Benzene and toluene, volatile organic compounds that can cause neurological problems.. - ...
The term landfill is usually shorthand for a municipal landfill or sanitary landfill. These facilities were first introduced early in the 20th century, but gained wide use in the 1960s and 70s, in an effort to eliminate open dumps and other "unsanitary" waste disposal practices. The sanitary landfill is an engineered facility that separates and confines waste. Sanitary landfills are intended as biological reactors (bioreactors) in which microbes will break down complex organic waste into simpler, less toxic compounds over time. These reactors must be designed and operated according to regulatory standards and guidelines (See environmental engineering). Usually, aerobic decomposition is the first stage by which wastes are broken down in a landfill. These are followed by four stages of anaerobic degradation. Usually, solid organic material in solid phase decays rapidly as larger organic molecules degrade into smaller molecules. These smaller organic molecules begin to dissolve and move to the ...

According to research published today in the International Journal of Epidemiology, health is at risk for those who live within five kilometres of a landfill site. Researchers in Italy evaluated the potential health effects of living near nine different landfills in the Lazio region, and therefore being exposed to air pollutants emitted by the waste treatment plants. 242,409 people were enrolled in the cohort from 1996 to 2008.. The results showed a strong association between Hydrogen Sulphide (used as a surrogate for all pollutants co-emitted from the landfills) and deaths caused by lung cancer, as well as deaths and hospitalizations for respiratory diseases. The results were especially prominent in children. The annual average exposure levels of Hydrogen Sulphide was 6.3 ng/m3, compared to people living close to larger landfills in Rome whose levels averaged 45.ng/m3. At the end of the follow-up period there were 18,609 deaths.. Co-author Francesca Mataloni commented that, The evidence on the ...

Give thanks - then compost!Since this is Thanksgiving week here in the U.S., a time when we are at our most gluttonous, composting is a timely issue. In fact, Im putting together a video with tips for getting started - keep an eye out for it.. In the meantime, your question is an interesting one. Are yard and food scraps the key to quicker decomposition in landfills? The answer is no. In fact, such organic waste is the bane of a landfill operators existence; it takes up a quarter of the space and is a major source of methane, a greenhouse gas thats twenty times more potent than carbon dioxide. Paper is also a problem: its another major source of methane, and accounts for about a third of our municipal solid waste.. This is why composting and recycling are so important. Here in the U.S., we are better about "recovering" paper and yard waste than food waste: In 2007, according to the EPA, we recycled 54 percent of our paper and composted 62 percent of yard waste. When it comes to food waste, ...
When gypsum drywall is disposed in landfills, a series of biological and chemical reactions can occur that have the potential for adverse environmental impacts. When drywall in a landfill gets wet, some of the sulfate from the gypsum dissolves into the water. If this "leachate" reaches the groundwater, contamination with sulfate may result. The US federal secondary drinking water standard for sulfate is 250 mg/L. Concentrations above this level have been observed in the groundwater at unlined C&D debris landfills. The sulfate also contributes to the high total dissolved solids (TDS) concentrations observed in groundwater at many C&D debris landfills.. Another issue results form the biological conversion of dissolved sulfate to hydrogen sulfide (H2S). H2S is a foul-smelling gas (rotten eggs). It is produced under wet, anaerobic conditions, such as those that often occur in landfills. The presence of organic matter such as yard trash or cardboard is needed for the microorganisms to thrive, but ...

Since at least 2009, the Pennsylvania Department of Environmental Protection has allowed 14 sewage waste treatment plants to leak radioactive fracking waste into 13 Pennsylvania waterways, according to an investigation by Public Herald. When the Pennsylvania landfills accept fracking waste, radioactive materials pulled from the earths core - some of which are carcinogens - contaminate the landfill leachate. Duke Universitys Avner Vengosh told Public Herald that because sewage plants cannot treat the radioactive material, they release it into waterways instead.. "Sanitary landfills are no place for drilling wastes that contain toxic metals, organics, and radioactive materials," John Stolz of Duquesne University told Public Herald. "The leachate from these landfills is so toxic it kills the microbes whose job it is to treat it." Public Heralds investigation estimates that between 500 million to 1.6 billion gallons of leachate could be released into Pennsylvania rivers per year. - By Rachael ...

Progress in Environmental Science and Engineering: Removal of Arsenic from Landfill Leachate by Selected Low-Cost Sorbents: An Experimental Study at the Zixiaguan Landfill of Wuhan City, Central China
A waste collector is a person employed by a public or private enterprise to collect and remove refuse (waste) and recyclables from residential, commercial, industrial or other collection site for further processing and disposal. Specialised waste collection vehicles featuring an array of automated functions are often deployed to assist waste collectors in reducing collection and transport time and for protection from exposure. Waste and recycling pickup work is physically demanding and it exposes workers to a number of occupational hazards. Statistics show waste collection to be one of the most dangerous jobs, at times even more dangerous than police work, but consistently less dangerous than commercial fishing and ranch and farm work. On-the-job hazards include broken glass; medical waste such as syringes; caustic chemicals; falling objects from overloaded containers; diseases that may accompany solid waste; asbestos; dog attacks and pests; inhaling dust, smoke, and fumes; inclement weather, ...

Go back. Health impacts of solid waste. Modernization and progress has had its share of disadvantages and one of the main aspects of concern is the pollution it is causing to the earth be it land, air, and water. With increase in the global population and the rising demand for food and other essentials, there has been a rise in the amount of waste being generated daily by each household. This waste is ultimately thrown into municipal waste collection centres from where it is collected by the area municipalities to be further thrown into the landfills and dumps. However, either due to resource crunch or inefficient infrastructure, not all of this waste gets collected and transported to the final dumpsites. If at this stage the management and disposal is improperly done, it can cause serious impacts on health and problems to the surrounding environment.. Waste that is not properly managed, especially excreta and other liquid and solid waste from households and the community, are a serious health ...
The Atlanta-Stephens Plant was acquired by Luck Stone in October 2018. The Construction & Demolition Landfill (C&D) operation has been established to accept construction/demolition waste, as defined by the Georgia Rules for Solid Waste Management. This waste differs significantly from household waste accepted at community solid waste landfills. The facility handles waste building materials and rubble resulting from construction, remodeling, repair, and demolition operations on pavements, houses, commercial buildings and other structures.
en] The degradation processes occurring within landfills are the keys to assessment and control of their environmental impact. This degradation results from different microbial activities interacting all along the landfill lifetime and influenced by several non-biological factors. Approaching these complex biological and chemical processes requires a multidisciplinary pattern. Thanks to Walloon Region support, we have developed a pattern or model combining the evolution of different key parameters. Such parameters qualify biogas (composition, production rate), leachate (pH, BOD5, COD, volatile fatty acids, redox potential, nitrogen balance, humic acids...), or solid waste (moisture, settlement, cellulose content...). This paper presents relationships, including our model, between these parameters. Variations of pH, BOD5/COD ratio, sulphate concentration in leachates and settlement measures allows to predict landfill age since completion. Evaluation of cellulose and water content in refuse as ...
UK research suggests an increase in serious birth defects in babies born to mothers who live within two kilometres of a landfill site
The legal requirements for wastewater discharge into environment, especially to zones exposed to eutrophication, lately became stricter. Nowadays wastewater treatment plants have to manage with the new rules and assure better biogenic elements removal, in comparison with the past. There are some well-known methods of diminishing concentrations of these compounds, but they are ineffective in case of nitrogen-rich streams, as landfill leachate or reject waters from dewatering of digested sludge. This wastewater disturbs conventional processes of nitrification-denitrification and raise necessity of building bigger tanks. The partial nitritation followed by Anaerobic Ammonium Oxidation (Anammox) process appear to be an excellent alternative for traditional nitrification/denitrification. The process was investigated in three different reactors - Membrane Bioreactor (MBR), Moving Bed Biofilm Reactor (MBBR) and Rotating Biological Contactor (RBC). The process was evaluated in two options: as a ...

On a planet encountering so many enormous challenges as ours, it is inevitable that humans would strive to figure out ingenious solutions to counteract the devastation caused by the impact of these challenges on Earths systems. One example is Waste-to-Energy (WtE), which can indeed hit two birds with one stone.. While waste presents a pressing challenge on the environment with an estimated 2.12 billion tons produced globally each year, the world is desperately seeking renewable energy sources to substitute depleting harmful fossil fuels. What science offers in the case of WtE is a technology that helps us "clean" the environment and generate "clean" energy at the same time; that is just wonderful?. Typically, there are two main waste management strategies used to reduce its hazards on the environment and public health; namely landfills and incinerators.. Landfills are the oldest form of waste treatment. Landfills have several drawbacks, however; besides being ugly and smelly, rainwater finds ...

... is a mixture of methane and carbon dioxide, with a number of other trace components. It is produced naturally as organic matter in landfill sites decomposition. It comprises approximately 60% methane which is a highly potent greenhouse gas - around 20 times more powerful in global warming potential than carbon dioxide. Generating energy from landfill gas avoids the methane gas escaping into the atmosphere and adding to the greenhouse warming effect. Extracting landfill gas and using it for energy reduces the escape of methane to the atmosphere. Waste management companies have environmental compliance obligations to prevent landfill gas escaping, but the efficiency of collection is improved when there is an incentive to collect it. When used to generate power (or for other energy uses) it helps prevent global warming and reduces the need for energy imports.. The methane in landfill gas is not fossil fuel methane (like natural gas or North Sea gas) - it is a form of biogas. It is ...

The methodology used to estimate USPS GHGs is explained in full in Appendix A. However, a brief description will help provide a rationale for the reported numbers. Direct energy use in Postal facilities and vehicles was converted to carbon equivalents through the use of standard conversion factors taken from DOE sources. USPS electricity use was broken out by fossil fuel source using national data, and these fuels then converted to carbon equivalents. Solid waste disposal was estimated for one year from survey data and extrapolated to others, with national GHG factors for solid waste disposal then applied to USPS quantities. Landscaping GHGs were estimated from data on pervious acreage at Postal Service facilities and assumptions concerning the fuel consumed in mowing such acreage. GHGs from third party transport were estimated by calculating proportions of freight that mail constituted, and applying these against total fuel consumed.

The removal of small craters (<20 m diameter) and the change in the albedo of the surface may cause a slight darkening of the regolith. However, it is not expected that this change will be visible from the Earth even with powerful telescopes. The release of lunar volatile gases and their effect on the lunar atmosphere is expected to be both local and temporary (on the order of a few weeks from the time of release). The solution to solid waste disposal is to recycle as much as possible and to bury the non-recyclable waste. The lack of wind and water means that the waste will stay localized indefinitely and cause no contamination of the environment. The positive benefits of using lunar 3He in terrestrial fusion plants far outweigh the detrimental effects of mining. The reduction in
Closed landfills can be a source of VOC and odorous nuisances to their atmospheric surroundings. A self-designed cylindrical air flux chamber was used to measure VOC surface emissions in a closed industrial landfill located in Cerdanyola del Vallès, Catalonia, Spain. The two main objectives of the study were the evaluation of the performance of the chamber setup in typical measurement conditions and the determination of the emission rates of 60 different VOC from that industrial landfill, generating a valuable database that can be useful in future studies related to industrial landfill management. Triplicate samples were taken in five selected sampling points. VOC were sampled dynamically using multi-sorbent bed tubes (Carbotrap, Carbopack X, Carboxen 569) connected to SKC AirCheck 2000 pumps. The analysis was performed by automatic thermal desorption coupled with a capillary gas chromatograph/mass spectrometry detector. The emission rates of sixty VOC were calculated for each sampling point in ...

Phospholipid fatty acids (PLFAs) were analysed at different time periods during composting of two waste mixtures rich in fats, M1 (22%) and M2 (39%), with the aim of monitoring changes in microbial community structure. The two mixtures consisted of a sludge sample collected from a vegetable oil refinery effluent treatment plant combined with household wastes. The PLFA profiles of both mixtures revealed that, at the start of the process, fungi and Gram-negative bacteria (GÀ) were more abundant in M2 than in M1. During the thermophilic phase, branched PLFA (i15:0, a15:0, i16:0, and i17:0) markers of Gram-positive bacteria (Gþ), became more abundant in M1, while G- bacteria were predominant in M2. The PLFA profiles in M1 representing non-specific, Gþ and GÀ bacteria as well as fungi decreased during the cooling phase (maturation) while an increase was recorded in M2, which was richer in fats. The ShannoneWeaver diversity index (Ish) showed a greater increase during M1 composting (from 0.69 to ...
Find 15697 landfills and dumps. Landfills provide information on dump stations, transfer stations, waste management, trash disposal, hazardous waste, and sanitation.
Two cities have landfills that affect the groundwater in the area. The larger city has 2,000,000 people, and the smaller city has 1,000,000. Leakage from the landfill in the larger city will cause 8 cases of cancer per year. Leakage from the landfill in the smaller city will cause 4 cases of cancer per year. Funds for cleanup are limited. The following options are available: 1. Partially clean up both landfills. The number of cancer cases would be reduced from 8 to 4 cases in the larger city and from 4 to 2 cases in the smaller city. 2 Totally clean up the landfill in the smaller city and partially clean up the landfill in the larger city. The number of cancer cases would be reduced from 8 to 7 cases in the larger city and from 4 to 0 cases in the smaller city. 3. Concentrate on the landfill in the larger city, but partially clean up the landfill in the smaller city. The number of cancer cases would be reduced to from 8 to 3 cases in the larger city and from 4 to 3 cases in the smaller city ...

Zero waste is no easy goal. Implementing our citywide organics program is our largest operational change in 25 years - and our success depends upon leading 8.5 million New Yorkers to develop new lifelong habits. Thats why were making it easier for everyone to do their part.. To achieve zero waste, we are working to develop programs that deal with each of the types of materials that New Yorkers throw away. Think food scraps, food-soiled paper and yard waste. Together, they comprise nearly one-third of what we send to landfills. Instead, were collecting that material to transform it into compost for our soil and clean energy to heat our buildings - and were making it easier for people to help by expanding curbside organics collection and food waste drop-off sites. By contrast, single-use plastic bags require a different strategy. Theyre not easily recycled - and New Yorkers use more than 9 billion of them each and every year. Most of them wind up in landfills, where they may take thousands of ...
The first such structure of its kind in Quebec, this city building is one of the components of the major mixed-use real estate project known as Cité Verte. This project is designed to showcase not only the innovative uses of wood and green technologies but also the particular features of an underground vacuum waste collection system.. This glulam post-and-beam structure supports both the lightweight wood truss roof and the 20-ton overhead bridge crane. This innovation made use of hefty engineered wood columns as well as a diaphragm made out of open web wood joists braced by two plywood panels, which transferred lateral forces to the steel bracing installed on the perimeter. All of the following components were made entirely from wood: wall sidings; fascia boards, soffits and screens; wall framing; non-load-bearing partitions; and the structure of the above-ground section.. In what amounts to an as-yet unconventional practice in industrial construction projects, maximum use has been made of wood ...

Water samples from four water bodies that flow through some solid waste dump sites in the Accra metropolitan area of Ghana were analysed over a period of six months for Cd, Pb, Cu, Zn and Mn contents; coliform bacteria and helminth eggs. Other water quality parameters such as BOD, DO, suspended solids and turbidity were also assessed. Cd, Pb, Zn, Mn, and Cu were determined using flame atomic absorption spectrometry (FAAS). Faecal coliforms, total coliforms and helminth eggs were determined by the membrane filtration (MF) method. The water samples contain various levels of Cd, Pb and Mn; Zn and Cu levels were low and found to be below the detection levels of the instrument in most cases. Helminth egg counts in water samples were high; an indication that the water bodies were polluted with pathogens. It has been observed that the major sources of pollutants into the water bodies were organic waste as well as coliform bacteria derived from these waste dumps. The elevated levels of bacteria make the water

Hydrogen sulfide in a landfill is reduced by dispersing a hydrogen sulfide control agent, such as an iron compound, into the landfill. The hydrogen sulfide control agent may be a component of an injected foam. Gas is also recovered from the landfill by introducing water into the landfill, as part of the foam, to promote digestion of organic matter.

Plant cover on landfills contributes to its landscape and assists in the reduction of leachate discharge through evapotranspiration. The latter function is particularly important if the landfill is not capped with an impermeable layer to control infiltration. Other benefits provided by the vegetation cover include visual improvement of the site, creation of wildlife habitat, and the sequestration of greenhouse gases. The species chosen for revegetation purpose depends on the afteruse of the site, climatic conditions, nursery stock availability, and hardiness of the species.. Despite the tremendous efforts and investment devoted to site engineering, the inclusion of a soil cover does not guarantee the successful establishment of vegetation. The depth and quality of the soil layer affect revegetation as a thicker soil cover is required for woody species which have deeper root systems.. Poor vegetation performance is a common feature of many old landfills. In the US, a nationwide survey conducted ...
One of the more promising processes for the energetic transformation of waste is the anaerobic digestion of the Organic Fraction of Municipal Solid Waste. An experimental campaign was carried out on three different samples of OFMSW from Waste Separation, one as received and two obtained after mechanical treatment: OFMSW slurry (liquid fraction) and OFMSW Waste. Anaerobic Biogasification Potential and anaerobic digestion tests were carried out, investigating the effects of inoculum and pH. The OFMSW Waste was also examined to evaluate the possibility to dispose of it in a landfill. ...
If the current COVID-19 pandemic can teach us anything, its the importance of having a strong public health infrastructure. State and local health agencies maintain core capabilities critical to promoting and protecting the publics health, in both times of crisis and calm.. Though often associated with tackling chronic and infectious disease, the significance of the state public health infrastructure extends far beyond that. In many states, state health agencies (SHAs) are accountable for protecting community resources the population relies heavily on, like inspecting and regulating hospitals and emergency medical services, laboratories, nursing homes, and even, in some jurisdictions, solid waste disposal sites and haulers.. This infrastructure depends on its resources and support. This recent brief outlines SHA resource and capacity trends since 2010 based on data from the ASTHO Profile, a comprehensive survey of the structures, functions, and resources of state and territorial health ...
