Prevention - preventing and reducing waste
Reuse and preparation for reuse - giving the products a second life before they become waste.
Recycle - any recovery operation by which waste materials are reprocessed into products, materials or substances whether for the original or other purposes. It includes composting and it does not include incineration.
Recovery - some waste incineration based on a political non-scientific formula that upgrades the less inefficient incinerators.
Disposal - processes to dispose of waste be it landfilling, incineration, gasification and other finalist solutions (Wikipedia, 2010b).
Recycling e-waste helps recover important natural resources, like silver and gold, for reuse and decreases environmental impact. Recycling is a better, environmentally friendly solution, far better finding these metals in existing products, exploiting new places and impacting the environment more. Recycling is basically the science of reusing waste thus detrimental effects to environment is minimalized.
