I was at Technical Knock Out a while back. They disassemble every part of a computer to be recycled, right here in the USA. This box of heat sinks caught my eye. Made of copper and aluminum , they keep a computer cool. Once demanufactured , the metal will be melted down and used again. Last year, TKO recycled over 169 TONS of metal alone. Their total recycling of all components reached 1, 720,000 pounds last week. This is Alabama's leading electronic recyler!!!
