Re: Not much of a chemist then?
Sure. we can find a substitute.
You want to be responsible for doing all the materials tests all over again, taking months if not years, and pay for it from your tax?
You want to be responsible if the fivers start falling apart after "only" five years?
You want to be responsible for whatever media comeback when THAT material is less environmentally friendly than even the cow-notes?
You want to be responsible for the price difference in materials (tallow is basically a waste product, isn't it, and 23kg for ALL the notes isn't going to cost you much)?
You want to be responsible for when the dye or security feature has to be changed because it's not compatible with whatever substitute, and so on?
It's not just a case of "use something else", such things are planned years in advance because that money has to last 20-30 years in the field without any kind of maintenance.
