Recycling Rules: Understanding Recycling and a MRF

In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques. Learners identify four ways recyclable materials can be separated and sorted at a MRF: conveyor belts, blowers, flotation, and magnetism.
