Waste

Waste and wastes are unwanted or unusable materials. Waste is any substance which is discarded after primary use, or it is worthless, defective and of no use.

The term is often subjective (because waste to one person is not necessarily waste to another) and sometimes objectively inaccurate (for example, to send scrap metals to a landfill is to inaccurately classify them as waste, because they are recyclable). 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.

Types

There are many waste types defined by modern systems of waste management, notably including:

Waste (play)

Waste is a play by the English author Harley Granville Barker. It exists in two wholly different versions, from 1906 and 1927. The first version was refused a license by the Lord Chamberlain and had to be performed privately by the Stage Society in 1907; the second was finally staged in public at the Westminster Theatre in 1936.

Plot

The plot centres around ambitious independent politician Henry Trebell, his plans for a bill to disestablish the Church of England and his fall from grace and suicide after his affair with married woman Amy O'Connell, who dies after a botched abortion. The title may refer to the waste of his potential talents due to the scandal, the loss of the disestablishment bill and the termination of Amy's pregnancy.

Tire

A tire (American English) or tyre (British English) is a ring-shaped vehicle component that covers the wheel's rim to protect it and enable better vehicle performance. Most tires, such as those for automobiles and bicycles, provide traction between the vehicle and the road while providing a flexible cushion that absorbs shock.

The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric and wire, along with carbon black and other chemical compounds. They consist of a tread and a body. The tread provides traction while the body provides containment for a quantity of compressed air. Before rubber was developed, the first versions of tires were simply bands of metal that fitted around wooden wheels to prevent wear and tear. Early rubber tires were solid (not pneumatic). Today, the majority of tires are pneumatic inflatable structures, comprising a doughnut-shaped body of cords and wires encased in rubber and generally filled with compressed air to form an inflatable cushion. Pneumatic tires are used on many types of vehicles, including cars, bicycles, motorcycles, buses, trucks, heavy equipment, and aircraft. Metal tires are still used on locomotives and railcars, and solid rubber (or other polymer) tires are still used in various non-automotive applications, such as some casters, carts, lawnmowers, and wheelbarrows.

Tyre, Lebanon

Tyre (Arabic: صور, Ṣūr; Phoenician: 𐤑𐤅𐤓, Ṣur; Hebrew: צוֹר, Tzor; Tiberian Hebrew צר, Ṣōr; Akkadian: 𒋗𒊒, Ṣurru; Greek: Τύρος, Týros; Turkish: Sur; Latin: Tyrus, Armenian Տիր [Dir]), sometimes romanized as Sour, is a city in the South Governorate of Lebanon. There were approximately 117,000 inhabitants in 2003. However, the government of Lebanon has released only rough estimates of population numbers since 1932, so an accurate statistical accounting is not possible. Tyre juts out from the coast of the Mediterranean and is located about 80 km (50 mi) south of Beirut. The name of the city means "rock" after the rocky formation on which the town was originally built. The adjective for Tyre is Tyrian, and the inhabitants are Tyrians.

Tyre is an ancient Phoenician city and the legendary birthplace of Europa and Elissa (Dido). Today it is the fourth largest city in Lebanon and houses one of the nation's major ports. Tourism is a major industry. The city has a number of ancient sites, including its Roman Hippodrome which was added to UNESCO's list of World Heritage Sites in 1979.
