6. Summary Thoughts EfW and hazardous waste incineration will provide the same thermal destruction and environmental protection, 100% destruction, emissions without health risks Pharmaceuticals, if not reverse distributed, should never be flushed, they should either be burned or rendered unrecognizable, unusable and landfilled Non-hazardous wastes should not be sent to hazardous waste incinerators JGW26706
