Municipalities and some large businesses like Waste Management, have their own pumps and probably get fuel from several different sources depending on their needs and physical location (with a large company in different states and provinces) so JBI would change nothing except the price they paid for the fuel. The other thing to understand is that JBI has nothing to do with how the fuel is distributed to vehicles or boilers, they would be told where and when to deliver it, the rest isn't their problem.
As far as how the infrastructure is paid for, if they don't already have it the partner pays for it out of the money they currently budget for transportation, tipping fees, and from savings for the fuel. Howto reported that a single company is going to save $8 million a year on transportation and tipping fees alone, any company having to provide a location for the processor and paying for a way to distribute "cheap" fuel, will do so while doing a happy dance as they count the money they save. As well, in some cases larger companies will be getting 20% of the fuel sales profit. JBI doesn't have to pay for a physical location and gets a steady stream of free and plentiful plastic.
Not understanding this issues with "stations."
