In second grade, Jiin Yun observed that recycling wasn't as straightforward as it seemed, even among well-intentioned individuals. Fast forward ten years, and now, 16-year-old Yun has not only authored a children's book on recycling but has also collaborated with her older sister to create an app providing information on recycling over 500 common items. Additionally, she founded The Recycling Dictionary, a nonprofit organization that conducts workshops throughout Orange County, California, educating younger students about effective recycling practices.

When Allison Mabbott and Justin Wolff set out to create their beauty brand, Junk Theory, their foremost concern was the post-consumer lifecycle of their products. Recognizing the limitations of recycling systems, especially in the U.S., they aimed for sustainability that transcended mere recyclability. They designed their cleanser without a pump, encouraging manual application with hands. Additionally, while their jars and bottles contained small plastic inserts, about 1 gram each, to ensure airtight seals, they chose aluminum packaging due to its superior recycling rates compared to plastics, bioresins, and glass.

The Crayon Initiative, a nonprofit based in the Bay Area, gathers used and unneeded crayons donated by households, eateries, and schools nationwide. These crayons are melted down and repurposed, reducing environmental waste. The rejuvenated crayons are subsequently distributed to art programs in children's hospitals throughout the United States, bringing joy to young patients during their hospitalization. Most recently, the nonprofit partnered with Staples U.S. to urge customers to contribute their used crayons, which will be sent to The Crayon Initiative for recycling and repurposing.
