Check out IEEE Spectrum columnist Paul McFedries' "E-cycling E-waste" to extend your mastery of the topic with terms like "upcycling" vs. "downcycling", "technical nutrients", "historic scrap" vs. "orphan scrap", "precycle", and others. Here's are some examples:

"The [Nokia] Remade is an example of upcycling , a form of recycling that takes used or recycled materials and creates a new product with a quality or value higher than that of the original materials. Materials that are designed to be upcycled are called technical nutrients. Traditional recycling is sometimes described as downcycling because the quality of the material degrades with each life cycle."
