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).

Certified wood is wood from sustainably managed forests.
Bamboo is a type of rapidly renewable material.
C example would not be considered any type of recycled material. If a manufacturing process uses scraps and puts them back in the assembly line, it is a good practice but it does not count towards pre or post consumer recycled content.
Recycled milk jugs are a post-consumer recycled product.
