shrot

shrot or scrap-heap (Polish: szrot, German: schrott) is a place where can be found recyclable and other material left over from product consumption, such as part of vehicles, building supplies, and surplus materials. Unlike waste, scrap has significant monetary value.

shrot is a tool for making recyclable chroot environment which can be run with schroot command.
