Pros and Cons
Advantages and Disadvantages. E-waste contains a lot of precious metals such as aluminium, copper, gold etc. Instead of throwing away the old electronic equipment in landfills or using new non-renewable resources it should be refurbished, re-used and recycled. ADVANTAGES Preserves natural resources Reduces greenhouse gas emission Reduces pollution

Electrochemical extraction of gold from wastes as
A simple one-step method for the extraction of gold from wastes as nanoparticles stabilized by phospholipids is demonstrated. This is achieved by applying an AC voltage for 5s to the gold-containing wastes, which act as the electrodes in a buffer solution containing a dispersed phospholipid (1,2-dioleoyl-sn-glycero-3-phosphocholine, DOPC).
