Green Dust

i am not the only one who thinks farming green dust is a nightmare. at the moment i endless run recruit with just one tome to hopefully get some greens to turn them into dust (even with one tome i opend a chest with 3 blues in it). it feels like a endless circle of farming. am i doing something wrong? is there an easier way to get green dust?
fatshark? have you any future tools in thought that helps us just a little bit more with farming materials?
