Green computing Green computing is the study and practice of using computing resources efficiently. Typically, technological systems or computing products that incorporate green computing principles take into account the so-called triple bottom line of economic viability, social responsibility, and environmental impact. This differs somewhat from traditional or standard business practices that focus mainly on the economic viability of a computing solution. These focuses are similar to those of green chemistry; reduction of the use of hazardous materials such as lead at the manufacturing stage, maximized energy efficiency during the product's term of use, and recyclability or biodegradability of both a defunct product and of any factory waste.
A typical green computing solution attempts to address some or all of these factors by implementing environmentally friendly products in an efficient system. For example, an IT manager might purchase Electronic Products Environmental Assessment Tool (EPEAT)-approved hardware combined with a thin client solution. As compared to a traditional desktop PC configuration, such a configuration would probably reduce IT maintenance-related activities, extend the useful life of the hardware, and allow for responsible recycling of the equipment past its useful life. An open industry standard called Advanced Configuration and Power Interface (ACPI) provides a standard programming interface that allows an operating system to directly control the power saving aspects of the hardware. This allows the system to automatically turn off components such as monitors and hard drives after set periods of inactivity. In addition, a system may hibernate, in which it turns off nearly all components, including the CPU and the system RAM, greatly reducing the system's electricity usage. To resume from this state, some components, such as the keyboard, network interface card, and USB ports may remain powered, to receive input from the user. ACPI itself is a successor to an earlier Intel-Microsoft standard called Advanced Power Management, which allows a computer's BIOS to control power management functions.

Network Used Computer Recycling Directory redistributed sell my laptop sell my laptop computer laptops Does recycling Save energy? There is controversy on just how much energy is saved through recycling. The EIA states on its website that "a paper mill uses 40 percent less energy to make paper from recycled paper than it does to make paper from fresh lumber." Critics often argue that in the overall processes, it can take more energy to produce recycled products than it does to dispose of them in traditional landfill methods. This argument is followed from the curbside collection of recyclables, which critics note is often done by a second waste truck in addition to the truck that picks up the regular trash.

The liquidators would normally require sanction to pay creditors and to make compromises or arrangement with creditors computer sales Kim Kardashian Liquidators are the officer appointed when a company goes into winding-up or liquidation who has responsibility for collecting in all of the assets of the company and settling all claims against the company before putting the company into dissolution surplus computer surplus computer laptop computer Economist Steven Lands burg has suggested that the sole benefit of reducing landfill space is trumped by the energy needed and resulting pollution from the recycling process. Others, however, have calculated through life cycle assessment that producing recycled paper uses less energy and water than harvesting, pulping, processing, and transporting virgin trees. By using less recycled paper, additional energy is needed to create and maintain farmed forests until these forests are as self-sustainable as virgin forests.

E-waste as Waste Electrical and Electronic Equipment is a waste type consisting of any broken or unwanted electrical or electronic appliance. Recyclable electronic waste is sometimes further categorized as a "commodity" while e-waste which can not be reused is distinguished as "waste". Both types of e-waste have raised concern considering that many components of such equipment are considered toxic and are not biodegradable. Responding to these concerns, many European countries banned e-waste from landfills in the 1990s.
