Chinese wind giant Goldwind is claiming a breakthrough in recycling waste from old turbine blades after finding a “golden ratio” that allows it to be reused as high quality 3D-printed material for new construction projects.

Goldwind has successfully used crushed raw material from decommissioned blades to help produce 3D printed products with “mechanical properties, durability and working performance… equal to that of conventional building concrete”, said the manufacturer.

To achieve the necessary quality, its researchers “constantly adjusted the ratio of various raw materials, as well as the particle size and gradation of the crushed blade particles.
