Recycle all that old junk into the original components, or extract intermediate components with this NO RECIPE junk compressor. Simply add junk into the container and, every 750 ticks, watch it get broken down into the direct components that built it. 750 ticks after that, watch those components turn into what they're made of, and so on. Since this is a container, there's no annoying recipes to set. Since it uses the Factorio APIs to lookup the recipes of whatever is in the container, it should work with any mod (I've tried with Beyond, Nuclear, and a few others) automagically.

Getting back fluids is currently only supported on Factorio 0.15. Any modded liquids will not work unless an item called "<liquid_name>-barrel" exists (e.g. lithium-brine-barrel or petroleum-gas-barrel). Modded liquids also haven't been tested with this mod as 0.15 is in beta.

Version 0.0.3: Updated for Factorio 0.15 and universal barrels. Fixed a cheat bug where if a recipe gives more than one product (e.g. ground pipes), players could get the full ingredient list back by just providing one product.
Version 0.0.2: increased HP to 2000, fixed the art to make it more in line with other Factorio sprites, changed the ingredients to be less of a cheat mod.
Version 0.0.1: initial release. Bad art, too easy to build compressor, 200 HP
