Post-consumer material - recycled material generated from the waste of household, commercial, industrial, or institutional end-users

Postconsumer recycled content - is the percentage of material in a product that was consumer waste. The recycled material was generated by household, commercial, industrial, or institutional end-users and can no longer be used for its intended purpose. It includes returns of materials from the distribution chain. Examples include construction and demolition debris, materials collected through recycling programs, discarded products (e.g., furniture, cabinetry, decking), and landscaping waste (e.g., leaves, grass clippings, tree trimmings). (ISO 14021)

Pre-consumer content - formerly known as post-industrial content, is the percentage of material in a product that is recycled from manufacturing waste. Examples include planer shavings, plytrim, sawdust, chips, bagasse, sunflower seed hulls, walnut shells, culls, trimmed materials, print overruns, overissue publications, and obsolete inventories. Excluded are materials such as rework, regrind, or scrap generated in a process and capable of being reclaimed within the same process that generated it (ISO 14021).


Pre-consumer content is content from industry scraps that was diverted from the waste stream and used for other purposes. Examples include sawdust, wood shavings, wood chips, and print overruns. Excluded are materials that are re-incorporated into the same manufacturing process that generated it.

Cabinetry made from walnut shells is an example of a pre-consumer recycled material.

Sawdust, shavings, and wood chips are pre-consumer material that can be used elsewhere, even if they are used for landscaping purposes.
