METHOD FOR PROCESSING OPTICAL FIBER WASTES

摘要

The invention relates to a method for comminuting optical fibers from optical fiber wastes comprising the following steps: a) coarsely comminuting the optical fibers in order to obtain coarsely comminuted optical fibers; and b) finely comminuting the coarsely comminuted optical fibers using a granular additive of a d50 value in the range of 0.1 to 5.0 mm as an aggregate in order to obtain finely comminuted optical fibers wherein the mixing ratio of optical fibers to the additive is 25/75 to 95/05 wt%.
