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.
According to the Basel Convention,
Under the Waste Framework Directive, 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:
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.
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.
Waste is unwanted or undesired material.
Waste, WASTE or W.A.S.T.E. may also refer to:
Engineering is the application of mathematics, empirical evidence and scientific, economic, social, and practical knowledge in order to invent, innovate, design, build, maintain, research, and improve structures, machines, tools, systems, components, materials, and processes.
The discipline of engineering is extremely broad, and encompasses a range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied science, technology and types of application.
The term Engineering is derived from the Latin ingenium, meaning "cleverness" and ingeniare, meaning "to contrive, devise".
The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) has defined "engineering" as:
Engineering has existed since ancient times as humans devised fundamental inventions such as the wedge, lever, wheel, and pulley. Each of these inventions is essentially consistent with the modern definition of engineering.
An audio engineer works on the recording, manipulation, mixing, reproduction, and reinforcement of sound. Audio engineers work on the "...technical aspect of recording—the placing of microphones, the turning of pre-amp knobs, the setting of levels. The physical recording of any project is done by an engineer ... the nuts and bolts." Many audio engineers creatively use technologies to produce sound for film, radio, television, music, electronic products and computer games. Audio engineers also set up and operate sound reinforcement systems for concert, corporate, theatre, sporting and other events.
Alternatively, the term audio engineer can refer to a scientist or professional engineer who holds a B.Sc. or M.Sc. who designs, develops and builds new audio technologies working within the field of acoustical engineering.
Audio engineering concerns the creative and practical aspects of sounds including speech and music, as well as the development of new audio technologies and advancing scientific understanding of audible sound.
The Cal Poly Pomona College of Engineering is the engineering college at California State Polytechnic University, Pomona (Cal Poly Pomona) located in Pomona, California, United States. With over 5,600 undergraduate students (as of fall 2015), it is the largest engineering college in Southern California, the second largest college of engineering in the California State University system, and the seventeenth largest engineering college in the United States. In 2013 U.S. News & World Report ranks Cal Poly Pomona's undergraduate program 14th in the nation (for Master's-granting universities), and mentions that Cal Poly Pomona "has one of the top ranked engineering programs, and graduates roughly 1 of every 14 engineers in the state of California."
Because of the hands-on approach to academics and undergraduate focus, the college of engineering at Cal Poly Pomona is among the most selective engineering colleges in the nation and most of its departments are currently declared impacted (hold stringent standards for admissions). For fall 2015, the college admitted 45.3 percent of its total freshmen applicants who held an average unweighted GPA of 3.72 (out of 4.00) and SATs of 1178 (out of 1600), making the college admissions process statistically comparable to the University of California campuses at Davis, Irvine, and Santa Barbara.
