My contract just finished up at Noxilizer, so I can end my self-imposed embargo, and write about what I did there.
Noxilizer uses a proprietary (and patent protected) NO2 based sterilization system.
NO2 is a powerful oxidising agent, and it has some advantages over other sterilization technologies: It operates at room temperature, and it leaves no residue.
A company called Eniware partnered with Noxilizer to create a sterilization unit that can operate in undeveloped ares.
It runs on batteries and used a gas generator (Copper and Nitric Acid), and after 8 hours the instruments in the chamber are sterilized
Below is a video of Eniware’s founder extolling the virtues:
