The answer to this is yes. It’s a little complicated because there are no good alternatives to traditional vapor decreasing. That’s why we are so confident about the HFO option. If you want a truly non-halogen solvent, that means no chlorine, no bromine, no iodine, and no flooring. You’re going to have to go to a vacuum vapor decreasing option. So, the vacuum systems are nice. We think they’re also sustainable, but they require a little bit more investment upfront on the equipment.
