TL;DR
Add a new recipe to convert Wood into either Spoilage or Nutrients.What?
I would add this recipe to unlock with Tree Seeding. I say either Spoilage or Nutrients, because the same goal would be accomplished either way, but Nutrients would be more rewarding for the player to utilize this while Spoilage would be simpler, imho.Why?
This comes around to the common critiques of Gleba, and one in particular I think can be fixed with this minor tweak without significantly overhauling the balance of the game. Currently, the Biochamber has limited utility outside of Gleba, at least compared to the Foundry and the Electromagnetic Plant, and a major reason is that it requires Nutrients. The Foundry and the Plant can be taken to any planet and plopped down to begin working without any additional steps or resources. But not the Biochamber, it needs Nutrients to function and those can only be acquired on two planets, Gleba and Nauvis.However, there is no production chain of Nutrients on Nauvis innately, you have to get them from either Biter Eggs or Fish, and both require player input or outside resources of some capacity, and undermine what I feel is a core theme of Gleba's researches - sustainability. Any usage of the Biochamber outside of Gleba is not sustainable for the long-term without player input or additional infrastructure to ship in Nutrients (or something to produce them like Bioflux) from Gleba.
The option to convert Wood to Spoilage/Nutrients folds into things perfectly. First, most trees on Gleba yield Spoilage of some sort anyway, so this is just an extension of that. Besides, obviously Wood should rot and decay like any other resource, but adding a spoilage timer to it would be an awful idea, thus it should be a recipe. With the ability to produce Nutrients from Wood, the Biochamber's viability on Nauvis skyrockets. With Agricultural Towers to automate seeding and harvesting of Trees, a steady supply of Nutrients could be maintained to fuel the player's Biochambers, and they could be integrated into the factory much more organically (no pun intended).
On the flip side, sustainable Nutrient production on Nauvis is not particularly game-breaking, because the Biochamber's non-oil recipes all require something from Gleba. The exception is Fish Breeding, so this would make it easier to amass Fish, but that's something extremely niche use.
