Puzzle #83: The New Job

Congratulations on your new job as an engineer: sanitation engineer, that is, for the town of Notbigville.

Today’s run covers the light manufacturing part of town. There is one long deadend road that you have to do garbage pickup for. There is the usual assortment of bins, and you can expect to have at least two truckloads of garbage.

You would like to do an quick and efficient job so that you can enjoy the rest of day (or alternatively have time to track down and murder the guidance counsellor who conned you into taking this job). What is the best way to go about it? (Yes, the garbage collection.)

Submit your answer to Gene Wirchenko <genew@telus.net>. Your answer should be in the form of a proof. That means to show how your answer must be correct. The deadline is Wednesday, January 7, 2015 at noon Pacific Time. I will post the answer shortly after.
