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. WtE is a form of energy recovery. Most WtE processes produce 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 Albert Fryer.

The first US incinerator was built in 1885 on Governors Island in New York, NY.

The first waste incinerator in Denmark was built in 1903 in Frederiksberg

The first facility in Czech Republic was built in 1905 in Brno.

Incineration

Incineration, the combustion of organic material such as waste with energy recovery, is the most common WtE implementation. All new WtE plants in OECD countries incinerating waste (residual MSW, commercial, industrial or RDF) must meet strict emission standards, including those on nitrogen oxides (NO_x), sulphur dioxide (SO₂), heavy metals and dioxins. Hence, modern incineration plants are vastly different from old types, some of which neither recovered energy nor materials. Modern incinerators reduce the volume of the original waste by 95-96 percent, depending upon composition and degree of recovery of materials such as metals from the ash for recycling.

Seychelles (ⁱ/seɪˈʃɛlz/ say-SHELZ; French: [sɛʃɛl]), officially the Republic of Seychelles (French: République des Seychelles; Creole: Repiblik Sesel), is an archipelago in the Indian Ocean. The 115-island country, whose capital is Victoria, lies 1,500 kilometres (932 mi) east of mainland East Africa. Other nearby island countries and territories include Comoros, Mayotte, Madagascar, Réunion and Mauritius to the south.

Seychelles, with a population of 90,024, has the smallest population of any independent African state; however, it does have a larger population than the UK overseas territory Saint Helena, Ascension and Tristan da Cunha.

History

The Seychelles were uninhabited throughout most of recorded history. Some scholars assume that Austronesian seafarers and later Maldivian and Arab traders were the first to visit the uninhabited Seychelles. The earliest recorded sighting by Europeans took place in 1502 by the Portuguese Admiral Vasco da Gama, who passed through the Amirantes and named them after himself (islands of the Admiral). The earliest recorded landing was in January 1609, by the crew of the "Ascension" under Captain Sharpeigh during the fourth voyage of the British East India Company.
