Landfill Fire
A landfill fire occurs when waste disposed of in a landfill ignites and spreads. Two types of landfills fires are generally recognized – surface fires and deep-seated fires. Surface fires typically occur in underdeveloped countries that lack capacity to properly cover waste with inert daily and intermediate cover. Modern examples of such fires include the Deonar and Ghazipur Landfills in India, Cerro Patacon Landfill in Panama and the New Providence Landfill in the Bahamas. In landfills that do not cover their waste with daily cover, air intrusion provides the oxygen required for increased biological activity decomposition that creates substantial heat and can cause material in the landfills to spontaneously combust.. If unchecked, spontaneous combustion fires in particular tend to burn deeper into the waste mass, resulting in deep seated fires. In the U.S. 40% of landfill fires are attributed to arson.

Waste
Waste (or wastes) are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero. Examples include municipal solid waste (household trash/refuse), hazardous waste, wastewater (such as sewage, which contains bodily wastes ( feces and urine) and surface runoff), radioactive waste, and others. Definitions What constitutes waste depends on the eye of the beholder; one person's waste can be a resource for another person. Though waste is a physical object, its generation is a physical and psychological process. The definitions used by various agencies are as below. United Nations Environment Program According to the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes a ...

Maalaea, Hawaii
Maalaea ( haw, Māalaea) is a census-designated place (CDP) in Maui County, Hawaii, United States. The population was 310 at the 2020 census. Maalaea is the site of a small boat harbor, as well as the Maui Ocean Center, and a Shinto shrine, as well as being the historical location for the original Maui Airport.

Landfill
A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s. In the past, refuse was simply left in piles or thrown into pits; in archeology this is known as a midden. Some landfill sites are used for waste management purposes, such as temporary storage, consolidation and transfer, or for various stages of processing waste material, such as sorting, treatment, or recycling. Unless they are stabilized, landfills may undergo severe shaking or soil liquefaction of the ground during an earthquake. Once full, the area over a landfill site may be reclaimed for other uses. Operations Operators of well-run landfills for non-hazardous waste meet predefined specifications by applying techniques to: # confine waste to as small an area as ...

West Lake Landfill
West Lake Landfill is a closed, unlined mixed-waste landfill located in Bridgeton, Missouri. It was featured in the 2015 documentaries ''The First Secret City'', ''The Safe Side of the Fence'' and the 2017 HBO documentary ''Atomic Homefront''. Its contents have been shown to include radioactive waste; it is thus also an EPA Superfund cleanup site. History The West Lake Landfill site originated in 1939 as a limestone quarry operated by the Westlake Quarry Company. Landfilling at the site began in the 1950s. In 1973, after having changed hands (and responsible oversight) several times, B&K Construction Co., a company contracted by Cotter Corporation, dumped a portion of the original stored radioactive material at a nearby storage facility. 8,700 short tons (7,900 tonnes) of leached barium sulfate, the material with the lowest relative radioactivity, was combined with 39,000 short tons (35,000 t) of topsoil to dilute the contaminated material at the landfill. The leached barium sulf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Republic Services
Republic Services is an American waste disposal company whose services include non-hazardous solid waste collection, waste transfer, waste disposal, recycling, and energy services. It is the second largest provider of waste disposal in the United States (as measured by revenue) after Waste Management Corporation. Company history Republic Industries was created as a waste disposal firm in 1981. Wayne Huizenga became chairman of the board in 1995, when Republic Industries began acquiring auto dealerships and car rental agencies. In 1998, Republic Industries spun off Republic Services as an IPO, and then changed its name to AutoNation. In June 2008, Republic became the second largest waste management company in the United States following the acquisition of its larger competitor, Allied Waste Industries, for $6.1 billion in Republic stock. The merged company retained the Republic Services name. The ''Wall Street Journal'' reported in June 2010 that Republic Services’ $4 billion ...

Hydrogen Sulfide
Hydrogen sulfide is a chemical compound with the formula . It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. The underground mine gas term for foul-smelling hydrogen sulfide-rich gas mixtures is ''stinkdamp''. Swedish chemist Carl Wilhelm Scheele is credited with having discovered the chemical composition of purified hydrogen sulfide in 1777. The British English spelling of this compound is hydrogen sulphide, a spelling no longer recommended by the Royal Society of Chemistry or the International Union of Pure and Applied Chemistry. Hydrogen sulfide is toxic to humans and most other animals by inhibiting cellular respiration in a manner similar to hydrogen cyanide. When it is inhaled or it or its salts are ingested in high amounts, damage to organs occurs rapidly with symptoms ranging from breathing difficulties to convulsions and death. Despite this, the ...

Landfill Liner
A landfill liner, or composite liner, is intended to be a low permeable barrier, which is laid down under engineered landfill sites. Until it deteriorates, the liner retards migration of leachate, and its toxic constituents, into underlying aquifers or nearby rivers, causing potentially irreversible contamination of the local waterway and its sediments. Modern landfills generally require a layer of compacted clay with a minimum required thickness and a maximum allowable hydraulic conductivity, overlaid by a high-density polyethylene geomembrane. The United States Environmental Protection Agency has stated that the barriers "will ultimately fail," while sites remain threats for "thousands of years," suggesting that modern landfill designs delay but do not prevent ground and surface water pollution. Chipped or waste tires are used to support and insulate the liner. Types There are certain levels of harmfulness in which the different types of trash have; therefore, there are diff ...

Leachate
A leachate is any liquid that, in the course of passing through matter, extracts soluble or suspended solids, or any other component of the material through which it has passed. Leachate is a widely used term in the environmental sciences where it has the specific meaning of a liquid that has dissolved or entrained environmentally harmful substances that may then enter the environment. It is most commonly used in the context of land-filling of putrescible or industrial waste. In the narrow environmental context leachate is therefore any liquid material that drains from land or stockpiled material and contains significantly elevated concentrations of undesirable material derived from the material that it has passed through. Landfill leachate Leachate from a landfill varies widely in composition depending on the age of the landfill and the type of waste that it contains. It usually contains both dissolved and suspended material. The generation of leachate is caused principally b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
