Clean burn

Published: Saturday 04 July 2015

Biological weapons, toxic industrial wastes and pesticides -- all could be destroyed safely and cheaply using a liquid-fueled rocket, claim researchers at the Russian Space Agency, Moscow. The rocket engine incinerator designed by Anatoly Papusha works on a high-velocity stream of waste, which passes through several stages. First the chemicals are heated by the engine and broken down at 3,500C, followed by oxidation at 2,000C. All toxic products are removed by a multi-stage cleansing process, including scrubbers that remove acidic gasses from the exhaust. The end products are neutral ash, water and non-toxic gases ( New Scientist , Vol 152, No 2055).
