First there should be machines for ''dissasembling'' materials into more basically forms
Compressed cells should be dissasembled into: nitrogen, oxigen, argon,neon, helium kripton, ozone...
Sea Water into Hidrogen ,oxigen and sodium (obviously) and a random value to find potasium, magnesium, sulphur
Slime would be a total random
And so on...
Then with the other machine, you can ''assemble'' these raw materials into things
like making custom nuclear fuel rods, making enough H2SO4 to use as liquid
purifing uranium and remove other particles for ''Perfect Uranium Rod''
The ashes 're a unused craft, they can be used for make a saturation into a liquid or purifiing it to make Potassium hydroxide!
