Municipal Solid Waste
Municipal solid waste (MSW), commonly known as trash or garbage in the United States and rubbish in Britain, is a waste type consisting of everyday items that are discarded by the public. "Garbage" can also refer specifically to food waste, as in a garbage disposal; the two are sometimes collected separately. In the European Union, the semantic definition is 'mixed municipal waste,' given waste code 20 03 01 in the European Waste Catalog. Although the waste may originate from a number of sources that has nothing to do with a municipality, the traditional role of municipalities in collecting and managing these kinds of waste have produced the particular etymology 'municipal.' Composition The composition of municipal solid waste varies greatly from municipality to municipality, and it changes significantly with time. In municipalities which have a well-developed waste recycling system, the waste stream mainly consists of intractable wastes such as plastic film and non-recy ...

Muthurajawela Wetlands
Muthurajawela is a marsh in Sri Lanka in the southern region of the Negombo lagoon, north of Colombo. The Muthurajawela Marshes are in area and the country's largest saline coastal peat bog. The marsh is notable for its unique and highly diverse ecosystem and is listed as one of 12 priority wetlands in Sri Lanka. "Muthurajawela" translates to "Swamp of Royal Treasure". The marsh is believed to have originated about 7,000 years ago. In 1996 of the northern part of the Muthurajawela marsh was declared a wetland sanctuary by the government, under the Flora and Fauna Protection Act, in recognition of its vast bio-diversity. The region supports 192 distinct species of flora and 209 distinct species of fauna, including Slender Loris, as well as another 102 species of birds. Some of the identified species have been shown to be indigenous to the marsh. The marsh is a major local and tourist attraction, primarily for sightseeing and boating tours, and the area also supports local ag ...

List Of Power Stations In Sri Lanka
Sri Lanka's electricity demand is currently met by nine thermal power stations, fifteen large hydroelectric power stations, and fifteen wind farms, with a smaller share from small hydro facilities and other renewables such as solar. Most hydroelectric and thermal/ fossil fuel–based power stations in the country are owned and/or operated by the government via the state-run Ceylon Electricity Board (CEB), while the renewable energy sector consists mostly of privately run plants operating on a power purchase agreement with the CEB. Per CEB's 2016 generation report released in mid-2017, the country has a total combined installed generation capacity of , of which 2,115 MW (52.65%) was from thermal (900 MW/22.40% from coal and 1,215 MW/30.25% from fuel oil), 1,726 MW (42.97%) from hydroelectricity, and the remaining 176 MW (4.38%) from other renewable sources such as wind, biomass, and solar. These generation sources produced a total of of electricity du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fly Ash
Fly ash, flue ash, coal ash, or pulverised fuel ash (in the UK) plurale tantum: coal combustion residuals (CCRs)is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases. Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash. In modern coal-fired power plants, fly ash is generally captured by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys. Together with bottom ash removed from the bottom of the boiler, it is known as coal ash. Depending upon the source and composition of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline), aluminium oxide (Al2O3) and calcium oxide (CaO), the main mineral compounds in coal-bearing rock strata. ...

Road Construction
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels" ...

Bottom Ash
Bottom ash is part of the non- combustible residue of combustion in a power plant, boiler, furnace or incinerator. In an industrial context, it has traditionally referred to coal combustion and comprises traces of combustibles embedded in forming clinkers and sticking to hot side walls of a coal-burning furnace during its operation. The portion of the ash that escapes up the chimney or stack is, however, referred to as ''fly ash''. The clinkers fall by themselves into the bottom hopper of a coal-burning furnace and are cooled. The above portion of the ash is also referred to as bottom ash. Most bottom ash generated at U.S. power plants is stored in ash ponds, which can cause serious environmental damage if they experience structural failures. Ash handling processes In a conventional water impounded hopper (WIH) system, the clinker lumps get crushed to small sizes by clinker grinders mounted under water and fall down into a trough from where a water ejector takes them out t ...

Sri Lankan Rupee
The Sri Lankan Rupee ( si, රුපියල්, ta, ரூபாய்; symbol: Re and Rs (plural) in English, රු in Sinhala, ௹ in Tamil; ISO code: LKR) is the currency of Sri Lanka. It is subdivided into 100 cents, but cents are rarely seen in circulation due to its low value. It is issued by the Central Bank of Sri Lanka. The abbreviation ''Re'' (singular) and ''Rs'' (plural) is generally used, the World Bank suggests SL Rs as a fully disambiguating abbreviation for distinction from other currencies named "rupee". History Sterling became Ceylon's official currency in 1825, replacing the Ceylonese rixdollar at a rate of £1 stg = rixdollars, and British silver coin was made legal tender. Treasury notes denominated in sterling were issued in 1827, replacing the earlier rixdollar notes. Rixdollar notes not presented for exchange were demonetized in June 1831. The Indian rupee was made Ceylon's standard coin on 26 September 1836, and Ceylon reverted to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thermal Power Station
A thermal power station is a type of power station in which heat energy is converted to electrical energy. In a steam-generating cycle heat is used to boil water in a large pressure vessel to produce high-pressure steam, which drives a steam turbine connected to an electrical generator. The low-pressure exhaust from the turbine enters a steam condenser where it is cooled to produce hot condensate which is recycled to the heating process to generate more high pressure steam. This is known as a Rankine cycle. The design of thermal power stations depends on the intended energy source: fossil fuel, nuclear and geothermal power, solar energy, biofuels, and waste incineration are all used. Certain thermal power stations are also designed to produce heat for industrial purposes; for district heating; or desalination of water, in addition to generating electrical power. Fuels such as natural gas or oil can also be burnt directly in gas turbines (internal combustion). The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
