This technology is revolutionary for plastic recycling! The 95% contaminant removal rate is impressive 👍
Does anyone know if these systems work well for mixed plastics? The article mainly focuses on PET and polyolefins.
The water recovery rates are decent, but I’m curious about 5-15% water loss – where does that go? 🤔
At $18-24/ton operating cost, how does this compare financially to virgin plastic production? Need more cost analysis.
Lol imagine paying a million bucks just to wash your trash 😂 But seriously though, we need this tech
Super happy to see plastic recycling get this advanced! Where can I invest in companies making these systems?
Hot take: These specs look great on paper, but I’ve visited facilities where the actual performance is way lower
The CO2 reduction equivalent to planting trees is such a smart way to explain environmental impact. More industries should do this!
Who else is fascinated by the ultrasonic cleaning tech? 40kHz cavitation sounds like sci-fi but it’s real!
Good overview, but I wish there was more detail on the AI optimization part. How exactly do the algorithms work?
That ultrasonic cleaning section blew my mind! 40 kHz cavitation is next-level stuff 👏
