Computer monitors are typically packed into low stacks on wooden pallets for recycling and then shrink-wrapped. [1]Electronic waste recycling, electronics recycling, or e-waste recycling is the disassembly and separation of components and raw materials of waste electronics; when referring to specific types of e-waste, the terms like computer recycling or mobile phone recycling may be used.
The directive imposes the responsibility for the disposal of waste electrical and electronic equipment on the manufacturers or distributors of such equipment. [5] It requires that those companies establish an infrastructure for collecting WEEE, in such a way that "Users of electrical and electronic equipment from private households should have the possibility of returning WEEE at least free of ...
The European Commission (EC) of the EU has classified waste electrical and electronic equipment (WEEE) as the waste generated from electrical devices and household appliances like refrigerators, televisions, and mobile phones and other devices. In 2005 the EU reported total waste of 9 million tonnes and in 2020 estimates waste of 12 million tonnes.
[112] [113] Digitunity is a non-profit organization that aims to collect used devices to donate it to those in need. [112] The World Computer Exchange accepts computer donations of electronics that they give to low-income communities worldwide. [113] Free Geek is a collectively run, non-profit organization based in Portland, Oregon. It aims to ...
Sources of electrical power: Battery – acid- or alkali-based power supply. Fuel cell – an electrochemical generator; Power supply – usually a main hook-up; Photovoltaic device – generates electricity from light; Thermoelectric generator – generates electricity from temperature gradients; Electrical generator – an electromechanical ...
A mathematical prediction of the flow of electric power in a network, based on a model of the actual or proposed system; necessary for planning of electrical grids. load following power plant A power plant that can economically be operated over a significant range of output, so as to meet varying electric power demand.
He had observed a number of very fine silver objects from ancient Iraq, plated with very thin layers of gold, and speculated that they were electroplated. In 1938 he authored a paper [ 10 ] [ 11 ] offering the hypothesis that they may have formed a galvanic cell , perhaps used for electroplating gold onto silver objects. [ 2 ]
In semiconductor detectors, ionizing radiation is measured by the number of charge carriers set free in the detector material which is arranged between two electrodes, by the radiation. Ionizing radiation produces free electrons and electron holes. The number of electron-hole pairs is proportional to the energy of the radiation to the ...
