While writing a previous article on green dental care, I found out about a great company called TerraCycle, which offers a program to accept “non-recyclable or hard to recycle waste,” such as toothbrushes and toothpaste tubes. After looking at the website , I decided TerraCycle deserved an article of its own! Started by a young Princeton student, TerraCycle began as a small business that sold worm casting fertilizer in used soda bottles. TerraCycle started expanding its business by producing various products out of post-consumer waste, such as pencil cases out of used CapriSun drink pouches. This process, called upcycling, involves producing new, useful products out of waste materials and useless products that otherwise would go to the landfill. So, upcycling helps reduce landfill waste and reduces resource use. TerraCycle quickly grew into a global project with over 20 countries now participating in their upcycling efforts.
