What to do with "mission items"

[Yummy]

so I have noticed that almost everytime in the same places these mission items spawn which i had to get in previous main missions but I already did the missions but they still spawn there, now my stash is filled with bunch of composite fiber containers, alloy components, control cores and radsource extracts. So what am I supposed to do with all these now? Can I sell them or do I need them for some crafting stuff? If its only for selling can I ignore these items in the future since they take so much space (3x3) and only sell for 10 gold. any info would be appreciated

Later in the campaign you'll get merchant who will buy them from you for a decent price in T and some for Research Point.
