Solid Waste Characterization Database

Residential Waste Disposal Rates

The table below contains values for residential waste disposal rates computed as part of the 1999 Statewide Waste Characterization Study. Per capita disposal rates were estimated for each of the five regions defined in the study--see the study for an explanation of how the regions were selected. A single statewide disposal rate for multifamily units (MFU) of 0.46 tons/unit/year was also computed. This rate should be used for all jurisdictions.

The table lists the counties and the regions to which each county was assigned, along with the estimated per capita disposal rates. Disposal rates are affected by a number of factors. Thus, these rates should only be used for planning purposes to aid in the design and development of solid waste programs. They should not be used as a measurement tool--see data limitations for more information.
