I am super interested in starting a small space... as in my garage. I have a place on the side of my yard where I could store close to 10 pallet sized "containers" where I could store various plastics.
Admittedly, I have been hesitant to purchase the required machinery to process the plastic for selfish reasons. However, my wife and I have discussed the need to do something completely altruistic to show our children and I think this would satisfy more than a few "conditions" that would enable an investment in said machinery.
That all said, how would you go about collecting plastic? I live in a suburban city that has a recycling program. Should I ask businesses? Do I need to cold call to get steady supplies? Picking stuff off the side of roads and whatnot seems good for a while, but how would I make dent if I cannot secure a reliable source?
