Printing always has chemistry in the background be it ink or cleaners or water treatments the list goes on and on.
The ideal chemistry is renewable bio derived and petroleum free. Printing does not have to sacrifice quality productivity and cost using biobased renewable consumables. If you have to dig it or mine it or drill it that is not cool. If you can grow it harvest it use it and renew it that is very cool. Ask you printer if they use biobased consumables. There is more to biobased printing that just paper.
