Heya, I was wondering if it was possible to make the parts of this mod containing biomass completely optional?
I am looking for a mod to deal with pollution that was better than one recipe but didn't add a bunch of new stuff to the game.
It would be cool if the different sections of the mod could be enabled and disabled.

Level 3 of the Tech takes away the requirement for biomass. Look at the screen shots and in game for the tech "Pollution Lessons Learned", you get the a new recipe and a new building. The Recipe and new building do the same things as the earlier research, but completely free from the biomass.

But what if I want to stop aliens dropping xenomass completely, to avoid cluttering with loads of dropped items?

Going back to the Lore of the previous versions of this mod and also modeling it on possible real world situations, I don't believe, in learning the process of filtering pollution from the aliens you should be able to control them. So having the things they drop Stop while still learning from those things is not appropriate. Though you could fork this, create a new level of Research in line with these and turn off the module in the code that drops the entities but that would be a hike to code as those entities are core to the Mod.
