Idea for harvesting debris which is too big to shred. Have a Laser Cutter Mod, Similar to the drill head, expect this cuts up debris it is pointed at. The other cost is creating containers for the scrap which is a 2x2x2 box with fits in a slots used for something like the solar panel on the rover. As you use the laser the box fills up similar to the way the soil canisters do and then when one is full, you can bring it to the shredder and scrap it for the scrap, this also destroys the container, so you would need to make another for collecting more scrap.
