Free feedstock by the truckload (literally). System powers itself. System runs itself. Employees merely load the system with plastic and are done.
Ummmmm......everybody needs to dumb down this to a 5 year old's level of understanding.. Where are these fictional costs some say won't make this profitable? The input costs are practically nil like making a cup of lemonade even a 5 year old gets that if you spend almost nothing to make something valuable you get a hilly profitable product.
The feedstock costs?
Nope.
Power costs?
Nope.
Employee costs?
Peanuts.
Everything is pretty much overhead, and even that isn't much. You have to literally make up costs.
