    Hi, I teach the “Waste Not Want Not: Repurposing Refuse as Resource” class at the Patel College of Global Sustainability and we now have a $5000 grant to purchase a Precious Plastics Shredder for our program. We would like to purchase the one you recommend (we need a single phase 240V 60Hz powered unit for use in Florida and it needs to be large and powerful enough to shred gallon milk jugs and detergent bottles and two liter PETE bottles without precutting). We can’t find the model you have depicted here. Do you have a direct link to the manufacturer (the link on the page just takes us to the general Precious Plastics website…)
    We have to purchase within the next couple of weeks.
    Thanks so much for your help!
