Reducing harm of garbage

Normally I talk about reducing harm associated with drugs but this time we are going to shift gears a little and talk about garbage. Could companies not save money by using less packaging? Just an idea, not only would it increase their profits but it would decrease waste in the dumps which would reduce harm generated due to garbage. It is unavoidable, we are going to have garbage. However, it is apparent we need more effective ways of dealing with it.
