Sustainably recyclable articles of manufacture and related methods

An article of manufacture that is sustainably recyclable, the article comprising:

• a first element comprising a first polymeric material comprising recycled first polymeric material or a combination of recycled first polymeric material and virgin first polymeric material with the first element having a first physical parameter;
• a second element comprising a second polymeric material comprising recycled second polymeric material, a combination of recycled second polymeric material and virgin second polymeric material, or 100% virgin second polymeric material with the second element having a second physical parameter;
• and
• the first polymeric material of the first element and the second polymeric material of the second element are substantially chemically similar and the first physical parameter of the first element and the second physical parameter of the second element are physically different and the article of manufacture comprising the first and second elements having an assigned overall impact footprint based on a life cycle assessment before manufacture of the article calculated by averaging multiple impact factors;
• the article of manufacture comprising the first and second elements having a sustainably recyclable ratio of less than one based on the assigned overall impact footprint of the article of manufacture based on the life cycle assessment measured against an assigned overall impact footprint based on the life cycle assessment of a reference design for a same type of article of manufacture calculated by averaging the same multiple impact factors, the reference design of the same type article of manufacture comprising at least one of a first element comprising 100% virgin first polymeric material or a second element comprising 100% virgin second polymeric material.
