Republic Services (RSG) president and CEO Donald Slager makes the case to potential investors pretty simple.

"Garbage is good," Slager tells TheStreet (TST) . "People like the stability of our cash flow and the predictability of what we do with that cash flow." Slager says Republic Services will return $3 billion of cash to shareholders over the next three years in buybacks and dividends.

It also helps to deliver good quarters, too. The company's first quarter adjusted earnings surged 35% from the prior year, fueled by strength in the large container business.
