One of the first manifestations of the green computing movement was the launch of energy star program back in 1992.

Energy Star served as a kind of voluntary label awarded to computing products that succeeded in minimizing use of energy while maximizing efficiency.

Energy Star applied to products like computer monitors, television sets and temperature control devices like refrigerators, air conditioners, and similar items.

Green Disposal

• Reuse: donate your computer components to people who may not have or have lesser quality computers.

• Refurbish: rather than discarding your computer upgrade it. Change its some of the parts in order to make it new. 

• Recycle: One of the major challenges is recycling the printed circuit boards from the electronic wastes. The circuit boards contain such precious metals as gold, silver, platinum, etc. and such base metals as copper, iron, aluminum.

• Europe has outlawed using landfills for computer components.

• Disposal of these devices constituted 20-50 million tons per year (about 5% of the total waste of the planet)

• This waste is called e-waste.• Toxic chemicals in electronics products can reach into the

land over time or are released into the atmosphere, impacting nearby communities and the environment.
