The manufacturers of wooden packaging materials are role models where sustainability is concerned. They commit to sourcing the sawn timber for wooden crates and pallets from sustainable, preferably regional forestry - this means that less wood is removed than will grow back. The vast majority of wooden packaging materials are used several times. At the end of their product life cycle, they can be excellently recycled for materials and energy, as they are made from untreated wood. The calorific value of these residual woods is almost as good as that of untreated forest wood. The perfect prerequisite for the installation of an ENDRESS wood combustion system for heat generation.
