One thing they were able to do is freeze their precooked egg patties that would have been thrown away for texture reasons for later use in a protein stock for a charitable kitchen's cafeteria in some way that I was not informed of.
This corporation was a prepared food retailer, not a grocery store in case I have been too unclear. In their case they used nitrogen-packed presliced tomato pans to streamline food prep for their line, which is why I chose tomatos as the example.
