About ENplus® Mark

ENplus® is an international certification scheme for wood pellets, in which producers and traders from all over the world are involved. It ensures the high quality of wood pellets used for heating family houses, social buildings and other facilities using pellet boilers.
This certification guarantees customers the purchase of wood pellets of high and sustainable quality from producers and traders under third-party supervision - the certification body.
