The oil savings stats are mind-blowing 👏 More industries need to adopt this tech
As someone working in plastic recycling, these water recycling rates are impressive! Much better than our current setup
Wonder if the food-grade washing can really remove all contaminants completely 🤔
LOL imagine explaining this process to someone from 50 years ago ‘yeah we melt down old bumpers to make toothbrushes’
The separation tech for glass fibers sounds perfect for our auto part recycling needs. Anyone know the price range?
Important work! The energy savings alone make this worth investing in
Our factory bought one of these last year – game changer! Output quality is way more consistent now
