Notes

1. “A diaper (also called a nappy in the United Kingdom) is a kind of underwear that allows one to defecate or urinate in a discreet manner. When diapers become soiled, they require changing; this process is often performed by a second person such as a parent or caregiver. Failure to change a diaper on a regular enough basis can result in skin problems.

Diapers are made of cloth or synthetic disposable materials. Cloth diapers are composed of layers of fabric such as cotton, hemp, bamboo or microfiber and can be washed and reused multiple times. Disposable diapers contain absorbent chemicals and are thrown away after use. Plastic pants can be worn over diapers to avoid leaks, but with modern cloth diapers, this is no longer necessary.[citation needed]

Diapers are primarily worn by children who are not yet potty trained or experience bedwetting. However, they can also be used by adults with incontinence or in certain circumstances where access to a toilet is unavailable. These can include the elderly, those with a physical or mental disability, and people working in extreme conditions such as astronauts. It is not uncommon for people to wear diapers under dry suits.”

(Diapers, Wikipedia, 7/30/2013)

2. During high speed manufacturing of disposable absorbent articles, such as diapers, defective products are discarded in landfills losing the costly absorbent particles.  These superabsorbent particles typically are more than 90% of the absorbent cores.  Michnacs, Luckert, and Zetzl recovered the absorbent particles by mixing the rejects with a thermoplastic melt such as styrene butadiene block copolymers, solidifying and extracting the thermoplastics, additives and contaminates with a supercritical carbon dioxide or propane leaving behind active, crosslinked superabsorbent particles.
US Patent 8,766,032 (July 1, 2014), “Recycled Superabsorbent Polymer Particles,” Marion Michnacs. Carsten Luckert, and Carsten Zetzl (The Procter & Gamble Company, Cincinnati, Ohio, USA).
