Did you know that the average garbage truck gets just 2.8 miles to the gallon of diesel fuel? It's true. In fact, garbage trucks get the worst fuel economy of any type of commercial vehicle.

Why such bad gas mileage? Well, garbage trucks are big, fleets tend to be pretty old, and their drivers have to make stops every few hundred feet while keeping engines running the whole time.

With this in mind, and with fuel prices soaring, it makes sense for municipalities, universities and businesses with large campuses to find ways to cut their garbage collection costs. The BigBelly Solar Compactor can help.

No bigger than any other outdoor garbage receptacle, the BigBelly uses the sun's rays to power an internal compactor which crushes its content, allowing it to hold five times as much as your average garbage can. This means it doesn't need to be emptied as often, which saves fuel costs, cuts labor costs, and reduces a whole lot of greenhouses gases in the process.

The BigBelly Solar Compactor costs $4,000 -- but BigBelly says the device can pay for itself in just a year and a half. And that's not trash-talk.
