Some food processes are complex. Ground beef is not. Making it involves taking the meat off the carcass, trimming the fat and putting it through a grinder -- either the industrial sized one or typically smaller sized ones that are found in the meat departments of any reasonable super market. As far as "but what are we going to do with those other trimmings?" -- go to any Asian or Hispanic supermarket and see for yourself -- they are sold to the same people who buy the ground beef under the name of "Beef trimmings" or "Beef bones" etc.
