In the rules it states
'Cargo containers and escape pods do not return any materials when recycled.'

The question is, does this relate to all cargo containers or just the ship variants. Specifically I wish to know if Items/droids in cargo containers yield anything when recycled.

Thanks in advance.

The cargo containers that hold items/droids never use any RMs to make, and thus never return any RMs when recycled. I can only assume the items inside the boxes would.

Cargo containers and escape pods can be generated without the use of any materials - recycling them for materials is considered an exploit and it was turned off. I'm like 75% sure that recycling items does not return materials either.
