This is super helpful for our recycling plant upgrade! Been looking for detailed tech specs like this.
Wow, had no idea sorting tech got this advanced. That 99.9% purity with magnetic separation is wild!
Anyone have experience with TOMRA sorters? Wondering if they’re worth the premium price.
The AI robotic sorters sound futuristic but 60-80 picks/min is insane! 😲
Great breakdown! Just a heads up – hydrocyclones can be tricky to maintain in humid climates.
Why no mention of plastic film sorting challenges? That’s our biggest headache right now.
We’ve been using CP Manufacturing’s system for 2 years. AMA about their turnkey solution!
The cost comparison chart would be more useful with actual dollar figures… just saying.
That sink-float tank throughput seems optimistic based on our experience. Maybe with perfect conditions?
The LIBS tech for black plastics is game-changing for e-waste recycling. Finally!
What about maintenance costs? These high-tech systems must need constant calibration.
Our facility still uses manual sorting… this article makes me feel like we’re in the stone age lol
