In Europe, you could get a very good price for Hazelnut oil (either from roasted nuts or raw ones), can be used as a gourmet oil, or in cosmetics. Those who know about hazelnut oil, place high value on it.
The nuts mixed in chocolate, it is a ingredient that creates a amazing flavour. Hazelnuts are local in many parts of Europe where almonds are not, but because almonds are more common ( and sometimes cheaper) they are often used intead of hazelnuts, but the flavour of roasted hazelnuts is amazing.
Plus all the things you could do with the wood itself.
Let's plant more hazel.
A couple years ago I attended an info session about growing hazelnuts commercially in eastern ontario. Turns out it was actually an info session about how we can't grow hazelnuts commercially...at least not for big companies. They said there was development happening to breed for a hardier tree that would still produce a large quality nut, but that the trials they had done weren't successful yet on a large scale.
Sorry I can't remember more info about it.
