Waste To Energy
Waste-to-energy (WtE) or energy-from-waste (EfW) is the process of generating energy in the form of electricity and/or heat from the primary treatment of waste types, waste, or the processing of waste into a fuel source. WtE is a form of energy recovery. Most WtE processes generate electricity and/or heat directly through combustion, or produce a combustible fuel commodity, such as methane, methanol, ethanol or synthetic fuels. History The first incinerator or "Destructor" was built in Nottingham, UK, in 1874 by Manlove, Alliott & Co. Ltd. to the design of Alfred Fryer. The first US incinerator was built in 1885 on Governors Island in New York City, New York, New York. The first waste incinerator in Denmark was built in 1903 in Frederiksberg.Waste to Energy in Denmark by Ramboll Consult The first facility in the Czech Repu ...

District Heating Plant Spittelau Ssw Crop1
A district is a type of administrative division that, in some countries, is managed by the local government. Across the world, areas known as "districts" vary greatly in size, spanning regions or county, counties, several municipality, municipalities, subdivisions of municipalities, school district, or political district. By country/region Afghanistan In Afghanistan, a district (Persian language, Persian ps, ولسوالۍ ) is a subdivision of a province. There are almost 400 districts in the country. Australia Electoral districts are used in state elections. Districts were also used in several states as cadastral units for land titles. Some were used as squatting districts. Cadastral divisions of New South Wales, New South Wales had several different types of districts used in the 21st century. Austria In Austria, the word is used with different meanings in three different contexts: * Some of the tasks of the administrative branch of the national and regional governme ...

Czech Republic
The Czech Republic, or simply Czechia, is a landlocked country in Central Europe. Historically known as Bohemia, it is bordered by Austria to the south, Germany to the west, Poland to the northeast, and Slovakia to the southeast. The Czech Republic has a hilly landscape that covers an area of with a mostly temperate continental and oceanic climate. The capital and largest city is Prague; other major cities and urban areas include Brno, Ostrava, Plzeň and Liberec. The Duchy of Bohemia was founded in the late 9th century under Great Moravia. It was formally recognized as an Imperial State of the Holy Roman Empire in 1002 and became a kingdom in 1198. Following the Battle of Mohács in 1526, the whole Crown of Bohemia was gradually integrated into the Habsburg monarchy. The Protestant Bohemian Revolt led to the Thirty Years' War. After the Battle of White Mountain, the Habsburgs consolidated their rule. With the dissolution of the Holy Empire in 1806, the Cro ...

Incinerator Bottom Ash
Incinerator bottom ash (IBA) is a form of ash produced in incineration facilities. This material is discharged from the moving grate of municipal solid waste incinerators. Once IBA is processed by removing contaminants, it can be used as an aggregate. Following processing, the material is termed ''IBA aggregate'' or ''processed IBA''. The aggregate uses include: * Bulk fill * Asphalt * Cement bound materials * Lightweight blocks * Pavement concrete Alternatively, if there are no local markets for the IBA the material is disposed of in a landfill. Recovery IBA is a secondary source of ferrous and non-ferrous (NFe) metals. Between 5-15% of the bottom ash is made up of ferrous materials, and 1-5% is NFe. Despite glass making up 10-30% of IBA, it is not systematically recovered in any processing plants. On average, 63 kg of ferrous materials are removed from a single tonne of ash. Risks Foam concrete made from IBA led to an explosion in the United Kingdom in 2009. It was discovere ... [...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.

Ministry Of The Environment Of Denmark
Ministry of the Environment of Denmark ( da, Miljøministeriet) is the Danish ministry in charge of almost all matters concerning environmental issues in Denmark. The head office is in Copenhagen. Created in 1971 as the Ministry of Pollution Combating ("''Ministeriet for forureningsbekæmpelse''"), it changed its name in 1973 to the current Ministry of the Environment. However, from 1994 to 2005 it was known as the Ministry of Environment and Energy ("''Miljø- og Energiministeriet''"), as the ministry was merged with the Ministry of Energy. In 2005, the energy sector was detached again and the ministry reverted to the old name. In a press release on 21 March 2007, the ministry announced that it would be hosting the COP-15 summit in 2009.(created on 1 January 2011 by a merger of Miljøklagenævnet and Naturklagenævnet) See also *Wind power in Denmark *Minister for the Environment (Denmark) Notes External links Ministry of the Environment 1971 establishments in Denmar ...

Acid Gas
Acid gas is a particular typology of natural gas or any other gas mixture containing significant quantities of hydrogen sulfide (H2S), carbon dioxide (CO2), or similar acidic gases. A gas is determined to be acidic or not after it is mixed with water. The pH scale ranges from 0 to 14, anything above 7 is basic while anything below 7 is acidic. Water has a neutral pH of 7 so once a gas is mixed with water, if the resulting mixture has a pH of less than 7 that means it is an acidic gas. The term/s ''acid gas'' and ''sour gas'' are often incorrectly treated as synonyms. Strictly speaking, a sour gas is any gas that specifically contains hydrogen sulfide in significant amounts; an acid gas is any gas that contains significant amounts of acidic gases such as carbon dioxide (CO2) or hydrogen sulfide. Thus, carbon dioxide by itself is an acid gas but not a sour gas. Dangers of acid gas Once a process burns a gas containing an acidic mixture, that acid gas is released into the atmosphere. T ...

Particulate
Particulates – also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter (PM) or suspended particulate matter (SPM) – are microscopic particles of solid or liquid matter suspended in the air. The term ''aerosol'' commonly refers to the particulate/air mixture, as opposed to the particulate matter alone. Sources of particulate matter can be natural or anthropogenic. They have impacts on climate and precipitation that adversely affect human health, in ways additional to direct inhalation. Types of atmospheric particles include suspended particulate matter; thoracic and respirable particles; inhalable coarse particles, designated PM, which are coarse particles with a diameter of 10 micrometers (μm) or less; fine particles, designated PM, with a diameter of 2.5 μm or less; ultrafine particles, with a diameter of 100 nm or less; and soot. The IARC and WHO designate airborne particulates as a Group 1 carcinogen. Particulates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heavy Metals
upright=1.2, Crystals of osmium, a heavy metal nearly twice as dense as lead">lead.html" ;"title="osmium, a heavy metal nearly twice as dense as lead">osmium, a heavy metal nearly twice as dense as lead Heavy metals are generally defined as metals with relatively high density, densities, atomic weights, or atomic numbers. The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic number, while a chemist would likely be more concerned with chemical property, chemical behaviour. More specific definitions have been published, but none of these have been widely accepted. The definitions surveyed in this article encompass up to 96 out of the 118 known chemical elements; only mercury, lead and bismuth meet all of them.

Sulphur Dioxide
Sulfur dioxide (IUPAC-recommended spelling) or sulphur dioxide (traditional Commonwealth English) is the chemical compound with the formula . It is a toxic gas responsible for the odor of burnt matches. It is released naturally by volcanic activity and is produced as a by-product of copper extraction and the burning of sulfur- bearing fossil fuels. Structure and bonding SO2 is a bent molecule with ''C''2v symmetry point group. A valence bond theory approach considering just ''s'' and ''p'' orbitals would describe the bonding in terms of resonance between two resonance structures. The sulfur–oxygen bond has a bond order of 1.5. There is support for this simple approach that does not invoke ''d'' orbital participation. In terms of electron-counting formalism, the sulfur atom has an oxidation state of +4 and a formal charge of +1. Occurrence Sulfur dioxide is found on Earth and exists in very small concentrations and in the atmosphere at about 1 ppm. On other planets, sul ...

Refuse-derived Fuel
Refuse-derived fuel (RDF) is a fuel produced from various types of waste such as municipal solid waste (MSW), industrial waste or commercial waste. The World Business Council for Sustainable Development provides a definition: ''"Selected waste and by-products with recoverable calorific value can be used as fuels in a cement kiln, replacing a portion of conventional fossil fuels, like coal, if they meet strict specifications. Sometimes they can only be used after pre-processing to provide ‘tailor-made’ fuels for the cement process".'' RDF consists largely of combustible components of such waste, as non recyclable plastics (not including PVC), paper cardboard, labels, and other corrugated materials. These fractions are separated by different processing steps, such as screening, air classification, ballistic separation, separation of ferrous and non ferrous materials, glass, stones and other foreign materials and shredding into a uniform grain size, or also pelletized in ord ...
