I would be careful in saying that a coffee based developer is environmentally friendly. You must also consider the effect of coffee growing on the environment. IIRC, rain forest is destroyed to make way for coffee plantations. In balance I think more harm is done than good. Things are never as simple as we first imagine them.

when i suggest that it is environmentally friendly i mean that the components
are NON TOXIC. it is coffee ( which you can drink )
washing soda ( which is baking soda with more water )
and vitamin c ( which you can take for a cold )
good points about the rain forest &C ... i hadn't thought about that ..
the robusto coffee that i used for my developer is the ugly cousin
of arabica coffee ... it is not liked by connoisseurs .. it is not shade grown &C ...
i wonder if it is grown in the same way that the more expensive "connoisseur-coffee" is grown,
in the plantations you mention...
i am seriously thinking of not buying anymore store bought print or film developer
after i run out of my ansco 130 and just using coffee developer for everythng...
i see no point in having more nasty chemicals in my house ... metol, HQ, glycin, KBr ..
nasty ... coffee, sodium carbonate, vit c .. non-toxic.
if i could grow my own, i would ...
