Researchers explore composite recycling solutions for additive manufacturing and more

September 28, 2020 | Case Study

We spoke with Professor Kazem Fayazbakhsh of Ryerson University, along with adviser Andrew Csinger, who, along with Professor Larry Lessard at McGill University, has developed a method of grinding waste turbine blades (or other fiber-reinforced composites) and in particular fractionating the ground material for use in different applications. Andrew explained that the bulk of the material is most suitable for mixing into concrete, which can provide additional strength but is a relatively low-value use. However, the ability to separate the recycled material effectively allows for the higher-quality fractions to go into higher-value uses, including as reinforcements for 3D printing materials.
