There's always the case of being in a limited closed system for the near term. So in that setting you have many byproducts
available as growing media that have degraded from their "new state" to some used condition after already having the launch energy
spent.
They are free by comparison to restocking anything not yet launched. The fraction of weight left over after a launch to orbit is
something like .2%. Another way to look at it is to price things by weight -- launched to orbit costs:

Atlas V $20.2k/kg as of 2015
Falcon Heavy $17k/kg as of 2016
Soyuz FG $7.2k/kg as of ?
SpaceX Falcon-9 $2.7k/kg as of 2016
SpaceX Falcon-9 re-used $1.9k/kg as of 2017
SpaceX planned BFR $75/kg future ??
