There are two types of front-load recycling dumpsters offered:
1.) Single Stream = plastic bottles, tubs, jugs, cardboard, and paper.   Recycling is discouraged and allowed in small amounts.
2.) Cardboard Only = Flattened non-waxy cardboard.
Pricing can fluctuate significantly depending on what municipality you are located in. Some areas have subsidized recycling programs and some do not. As such, it is not uncommon for people to actually pay *more* for a recycle dumpster than a trash dumpster of the same size.
