Your'e right, the only economical way to make something like this work is to set up a collection route. This in itself would cost in excess of $30k US Dollars. Figure 15-20k for a decent used pumper truck. A million dollar liability policy on your collection vehicle incase you spill and hazmat has to come out. In some states, you need a grease haulers permit. The 300 gal grease containers you see behind restaurants cost $700 +/- each. 55 gallon drums are $25 if you can find them used. On Avg you will see 50 gallons per month for each location, so you would need 100 bins in place to run this machine one day a week. Do the math on that. Then be willing to go get dirty and get it. WVO collection is getting more and more popular here in the US. Up until 3 or so years ago, restaurants had to pay disposal fees for thier grease removal. Now every last restaurant out there gets approached for thier grease quite often. There are plenty of people out there getting this stuff, and they all drive diesels. So the people qualified to invest in this know who they are.
