'Greener' epoxy resin

[smilie]

After a few hours on the sander I have almost got to the point where it’s time to get sticky on Subversion and sort the cracks and fill the odd ding. Being a bit of hippy at heart I’m thinking it would be good to be as good to the planet as possible while fixing up Subversion. After a bit research I have found this ‘Green Epoxy’ http://www.matrix-composites.co.uk/products-greenpoxy.html from Matrix mouldings.  
Has anyone used it? Or knows how good it is?
 
I have used their Sicomin products before and found them all pretty good, just wondering if this one is as good.
