Need help with materials

I'm creating a game in the low poly art style but because I'm creating objects in blender and adding materials to them in there then importing them into unity with the materials already applied. This creates the problem of having far too many draw calls as the materials are there for every object. This is the in-game statistics for it: http://imgur.com/KeWoja0

All I really need is suggestions on how I can reduce the batches to improve performance. Any help is appreciated! Thanks
