Wooden wind turbine blades can outperform conventional composites while reducing costs and improving recycling rates.
New wind turbine blades made of wood are designed to help improve overall sustainability and help alleviate wind turbine recycling issues milling machines with enabling it to cut costs, partly by replacing hand labor with automation.is reaching out to Voodin for more details about the types of wood used in its laminated lumber, and its potential for recycling.
Laminated veneer is different from cross-laminated timber. It is engineered to focus the wood grain on a lengthwise axis. Due to the type of joinery involved, LVL can be produced in much longer lengths than conventional lumber. “Popular LVL applications include headers and beams, hip and valley rafters, scaffold planking and the flange material for prefabricated wood I-joists,” the
The research effort comes under the acronym PECAN, though pecans are not involved. Aside from pushing fossil resources out of the supply chain, NREL states that its new PECAN resin involves 30% less energy and 40% less greenhouse gas emissions than conventional wind turbine blade epoxy. “The PECAN resin also hits the mark in the recyclability category. Manufacturers can depolymerize it using minimal energy or equipment and no harsh or nasty chemicals,” NREL also observes.for “Success Story” status. The last we heard, the company was planning to scale through a spinoff called Windfall, Inc., so we’ll keep an eye out for that.
