I'm not joking, this is from a FAQ sheet from Mutoh:
"Q: My waste tank is full. How do I discard the inks?
A: That is the beauty of the Mutoh Eco plus inks. They are ecologically friendly and
can be discarded down the drain in most areas. It is strongly recommended however, that you check with your local codes to ensure this is OK for your area."
Whaaatt??
Okay I'll check with my local council to see if it's okay to pour the following down the drain...
(This from Mutoh's own MSDS for their eco ultra inks)
Carbon black
Synthetic polymer
Diethylene glycol diethyl ether
Gamma-butyrolactone
Tetraethylene glycol, dimethyl ether
Tetraethylene glycol, monobutyl ether
Additives
Doesn't sound too bad does it??
I'm sure the fish will love it!
