Waste (also known as rubbish, trash, refuse, garbage, junk, and litter) is unwanted or useless materials.

Waste is linked to people development. Litter refers to waste disposed of improperly.

"Wastes are materials that are not prime products (that is products produced for the market) for which the generator has no further use in terms of his/her own purposes of production, transformation or consumption, and of which he/she wants to dispose. Wastes may be generated during the extraction of raw materials, the processing of raw materials into intermediate and final products, the consumption of final products, and other human activities. Residuals recycled or reused at the place of generation are excluded."

Under the Waste Framework Directive (European Directive 75/442/EC as amended), the European Union defines waste as an object the holder discards, intends to discard or is required to discard.

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

There are many issues that surround reporting waste. It is most commonly measured by size or weight, and there is a stark difference between the two. For example, organic waste is much heavier when it is wet, and plastic or glass bottles can have different weights but be the same size. On a global scale it is difficult to report waste because countries have different definitions of waste and what falls into waste categories, as well as different ways of reporting. Based on incomplete reports from its parties, the Basel Convention estimated 338 million tonnes of waste was generated in 2001. For the same year, OECD estimated 4 billion tonnes from its member countries. Despite these inconsistencies, waste reporting is still useful on a small and large scale to determine key causes and locations, and to find ways of preventing, minimizing, recovering, treating, and disposing waste.

Aamir Hussain Khan (pronounced [ˈaːmɪr ˈxaːn]) (born 14 March 1965) is an Indian film actor, director and producer who has established himself as one of the leading actors of Hindi cinema.

Starting his career as a child actor in his uncle Nasir Hussain's film Yaadon Ki Baaraat (1973), Khan began his professional career eleven years later with Holi (1984) and had his first commercial success with Qayamat Se Qayamat Tak (1988). He received his first National Film Award as a Special Jury Award for his roles in the films Qayamat Se Qayamat Tak (1988) and Raakh (1989). After eight previous nominations during the 1980s and 1990s, Khan received his first Filmfare Award for Best Actor for his performance in the major grosser Raja Hindustani (1996) and later earned his second Best Actor award for his performance in the Academy Award-nominated Lagaan, which also marked the debut of his own production company.

Following a four-year break from acting, Khan made his comeback playing the title role in the historical Mangal Pandey: The Rising (2005), and later won a Filmfare Critics Award for Best Actor for his role in Rang De Basanti (2006). The following year, he made his directorial debut with Taare Zameen Par, for which he received a Filmfare Award for Best Director. This was followed by Ghajini (2008), which became the highest grossing film of that year, and 3 Idiots (2009), which became the highest-grossing Bollywood film of all-time, unadjusted for inflation. The Government of India honoured him with the Padma Shri in 2003 and the Padma Bhushan in 2010 for his contributions towards the arts.
