Miscellaneous Inorganic Wastes: Material-Specific Data

The category of miscellaneous inorganic wastes in municipal solid waste (MSW) in this analysis includes soil, bits of concrete, and stones. For a complete list of other inorganic materials covered in this report, please see our A to Z directory.

This web page is a brief summary of data specific to miscellaneous inorganic materials not covered in our other material-specific web pages. For more comprehensive information, see the 2015 Data Tables on the Advancing Sustainable Materials Management: Facts and Figures Report page.

Overview

This is a picture for the overview section of miscellaneous Inorganic wastes. This picture is of gritty soil, which is an example of this type of waste.EPA measures the generation, recycling, composting, combustion with energy recovery and landfilling of miscellaneous inorganic wastes in MSW.

EPA found that miscellaneous inorganic wastes make up a relatively small portion of MSW. The Agency gathers data for this analysis from sampling studies. The category is not well-defined and often shows up in sampling reports in categories such as “fines” or “other.” This category generated an estimated four million tons of MSW in 2015, which was 1.5 percent of total MSW generation. The Agency could not identify information on the recovery (recycling or otherwise) of these materials.

The total amount of miscellaneous inorganic wastes in MSW combusted in 2015 was 780,000 tons. This represents 2.3 percent of all MSW combusted with energy recovery that year.

In 2015, landfills received about 3.2 million tons of miscellaneous inorganic wastes, which comprised 2.3 percent of all MSW landfilled.

Please see the EPA Methodology Document for further information on estimating the generation and management of miscellaneous inorganic wastes.
