Obviously for Bruno to travel to the US the deal would have to be significant.The only things that I know of in
the US that are significant is the Gilt Edge, the work with Penndot and Philladelphia water. (I'm sure there's a lot more). I think Philladelphia is the most exciting and an announcement is due any time.
A deal here would give VTI a huge amount of publicity and would certainly get the ball rolling for Virosewage in the US.
Although it could be to negotiate a partnership after the recent success with the Electroplating shop.
