I worked in a supermarket about 10 years ago as a stocker, among other things. A lot of our expired products were donated to various places, but a not-insignificant amount was also thrown away or literally poured down the drains due to laws preventing it from being sold or given away (IIRC). Also this is the end of the chain, I don't know how they operate at a higher level of distribution.
