There is currently no automated emc storage, but seeing as the aludel is already automatable you should add an alchemical urn which can store ash, minium/ verdant dust etc. As well as possibly oredictionary dust. It could be piped into with itemducts, or an "alchemical funnel". If placed next to a transmutation tablet, the dusts' emc should be usable in the tablet, but extracting from the tablet would still have to be manual.
