Wind turbines are widely recyclable – apart from their large rotor blades. As more wind farms get decommissioned, more blades end up in landfill or get burned, making recycling one of the industry's biggest PR and sustainability challenges.

Developers also pay increasing attention to emissions in the production of steel for towers.

Two start-ups, Germany's Voodin Blades and Sweden's Modvion, say they have found solutions – by making the components entirely out of wood. Energy Evolution correspondent Camilla Naschert discusses this with CEOs Tom Siekmann and Otto Lundman.
