This is a false equivalence. We regularly “throw away” remains (by burying or incinerating them) that could have been donated to science or organs that could have been donated to patients in need. Eating discarded meat seems more morally equivalent to ensuring that grandma is an organ donor. It’s not as if discarded meat in a landfill or buried Grandma’s in a cemetery are contributing in any meaningful way back to the ecosystem.
Moving files to the recycle bin and deleting files should take the same amount of time, both are essentially just a rewrite of the pointer to the data and don’t copy any data at all.
