To use this recycling theory for a given mineral, one has to make reasonable guesses about the values to use for the six parameters (R f, R i, t b, w, t p, w p) for that mineral. One way to confine some of the parameters is to fit the parameters to the known recycling rate for specific years, defined as the percent of consumption that is

Recycling Wikipedia

Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the properties it had in its virgin or original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas
