I work as operations foreman at a small airport in Canada. It’s my job to clean out the LAGs (Liquids and Gels) boxes which us where they put the stuff after seizing if from baggage searches before you get through security.
Most of it is shampoo, body wash and hairspray.

I also clean out the “sharps” boxes which is usually mostly scissors and leathermans and the odd bullet.

I keep some stuff which I donate to the local food bank or homeless shelters. Most of it gets thrown out.
