BALTEK®

Structural balsa cores

Natural, renewable resource - balsa wood

BALTEK® is the only structural core material made of a natural, renewable resource – balsa wood. The balsa tree grows fast, has low to medium density, and best-in-class weight-specific mechanical properties. It is the first carbon neutral core material in the world.

We own and manage several thousand hectares of FSC®-certified balsa wood plantations in Ecuador (FSC-C019065) and Papua New Guinea (FSC-C125018) - that's our commitment to watch out for virgin rainforest.

Availability and Plantations

Managing over 13.000 ha of FSC®-certified plantations in two independent world regions, we ensure a continuous global supply to industrial customers at any time.

This includes the production control from selecting the best seeds, growing perfect seedlings to the tree in Ecuador and Papua New Guinea with chain of custody certifications, making it more easy to adjust the balsa supply to your requirements.
