Sahara wants to be a James Bond film, no more than in the secret lair of the bad guy. Actually this lair is not secret at all, and does not want to destroy the world with lasers inside satellites. Instead it is a hazardous waste processing plant. The business of processing toxic chemicals is a big and controversial one. However it would appear that Sahara has come up with a perfect solution. Namely subject the chemicals to such high temperatures that they vapourize.
Vapourize. As in turn into vapour. As in therefore enter the atmosphere. Therefore can be spread quickly and easily as pollutants around the world. And incorporated with rain. To enter the water table. Which is exactly what the bad guy is doing in the first place.
Vapourize does not mean to completely and utterly destroy. The sun vapourizes puddles all the time.
