It need not be a waste, if you have an absorber that is large enough to convert most of the kinetic energy into heat. The material of the absorber can be something cheap, like water. That has the advantage that it immediately produces steam which can drive a turbine. >Muon production rate is low.

If the muons are absorbed in normal water, then the most likely fusion reaction would be H+D -> He3. Although the muons will also knock a few neutrons off Oxygen which will then be absorbed by either H or O16 resulting in either D or O17. The D is useful, and the O17 is harmless. The O15 left behind will decay to N15 which is also harmless. In fact, even the faster neutrons from the D-D or D-T reactions would be relatively harmless if absorbed in water, for the same reasons.
