This recycling system is a game-changer for sustainable agriculture! 👍
Wow, didn’t know 1 ton recycled film saves that much oil. Mind blown 🤯
The water recycling rate could be better tho. 85-90% still wastes so much
@CelestialRiddle：85-90% water recycling is solid for industrial processes. Compare it to other ag recycling – you’d be surprised how few hit those numbers.
Living near farms, I’ve seen these plastic films pile up everywhere. Finally a solution!
$750k investment for 2 ton/hr? Sounds pricey for small farms
That CO₂ snow blasting idea sounds dope but how practical is it?
@Fashionista：CO₂ blasting is already in use for niche applications. Scaling it up? That’s the billion-dollar question right there.
We use similar system at our CA farm – works better than advertised! Cut waste by 95%
Mobile processing units would be perfect for remote areas. Hope they develop that soon
AI contamination control? Now we’re talking! Tech meets sustainability
The enzyme cleaning part is cool but does it impact soil quality after?
That’s actually pretty impressive! Saving 5.8 barrels of oil per ton is no joke 🌱
