Allows you to dump the obsolete early-game items into a smelter to get the main resource back (usually iron plates).
Smelting time depends on the amount of resources the item contains.
Supported items: wooden chest, iron chest, small electric pole, boiler, steam engine, burner inserter, burner mining drill, pistol, shotgun, light armor, gun turret

Known limitations:
- Smelters only have one output, so you can only get one type of resource back (unless I also modify the smelters, which would increase incompatibilities with other mods).
- I only include items that become obsolete, can plausibly be smelted, do not contain excessive amounts of resources and are not upgraded to a better version.
- When combined with efficiency modules, making and smelting certain items in a loop can be used to generate infinite resources. If this disturbs you, don't do it.
