The old wooden windmill of Dutch paintings is having a come-back.
Modern wind turbine blades are difficult to recycle. So a Finnish and German company are developing laminated wood blades which are lighter, made mostly from renewable materials. The lighter the blade, the higher the tower can be, reaching faster winds.
By developing blades with sustainable wood – laminated veneer lumber (LVL) – Stora Enso and Voodin Blades can make the blades lighter and reduce dependency on fossil fuels.
LVL is a mass timber product that has a high-load-bearing capacity, and Stora Enso says it can easily support large-scale rotary blades. Unlike steel and concrete, LVL is relatively lightweight to transport on-site without heavy-duty equipment. LVL is also renewable with a minimal carbon footprint.
