Several meetings will be held this weekend. Two are particularly interesting:
-The exhibition "Building ecological" will be held from 3 to 5 December at the City of Science and Industry in Paris.
-The "Biomethanization in Agriculture" symposium will be held at the 3 and 4 December in Attert, Belgium (very close to the Luxembourg and French borders).
