Segment Reporting [Abstract]

Segment Reporting

9. SEGMENT REPORTING

We report selected information about operating segments in a manner consistent with that used for internal management reporting. We classify our solid waste operations on a geographic basis through regional operating segments. Revenues associated with our solid waste operations are derived mainly from collection, transfer, disposal, landfill, landfill-gas-to-energy and recycling services in the northeastern United States. Our revenues in the Recycling segment are derived from municipalities and customers in the form of processing fees, tipping fees and commodity sales. Organics services, ancillary operations, major customer accounts, discontinued operations, and earnings from equity method investees are included in our Other segment.
