Clan Scrap Recycler — what is it, how do I unlock it, who can build it, and how do I get scrap?

The Clan Scrap Recycler is a unique clan station that turns resources into scrap - one of the most valuable resources. You unlock it in the clan progression tree: the clan leader or an officer activates it there. It requires the previous progression level and enough clan currency (payable with coins), activation takes time and can be sped up for an extra cost. While running it consumes clan currency, and higher levels improve its output.
