If you use the V4 launcher, you don't need the recycleX lines.
Even under 3.x, it's not that great of a workaround, but it's all we've got. Each faction is supposed to have its own "how good we are at recycling" stat, and get different amounts of resources back. The Feds decomming a Fed Starbase, for example, will get fewer resources back than the Romulans decomming a Fed Starbase. The Klingons are even noted in the comments of their own racial ODF to be "eco-terrorists" because they're so bad at it!
