Mapping of potential end-users

The objective of this phase is to find users for the heat resource close to our production sites. We will achieve this by using our local network (mayors,etc…) and also by engaging with industrial and agricultural networks at regional and national levels in order to find new business willing to start an activity with cheap an sustainable heat.
