No, pointing out that what some people call waste is not actually being wasted, it is serving a useful purpose. "Waste" means it is serving no useful purpose at all.
It's fairly difficult to do something that serves no conceivable purpose. I could buy stuff and throw it straight into the trash and we could say it's not waste as I'm supporting manufacturing and the garbage industry.
If you care about limiting some wasteful practice, you have to pick some definition of what counts as waste.
