Technology’s environmental toll

January 23rd, 2003 § Comments off

A group of researchers at Japan’s United Nations University decided to find out what materials are needed to make a 32-megabyte memory chip, which weighs about two grams. Their findings: For each chip, manufacturers consume “32 kg of water, 1.6 kg of fossil fuels, 700 grams of elemental gases (mainly nitrogen), and 72 grams of chemicals (hundreds are used, including lethal arsine gas and corrosive hydrogen fluoride).”
