The growing adoption of powder-based additive manufacturing technology has led to the generation of more industrial metallic waste being produced. Although the additive process is not wasteful compared to conventional manufacturing, the problem of waste generation scales as manufacturers add more capacity to their production lines. Additive waste streams such as metal powders and filters can be safely recycled, contrary to some popular misconceptions. Misconceptions about the recyclability of metal powder waste include 1) that metal powders should be disposed of via incineration or landfilling; 2) all metal powders are hazardous; 3) there is no value in the material; and 4) metal powders are less recyclable compared to more conventional waste streams. In truth, additive metal powders and filters can be successfully recycled, thus reducing the environmental footprint of landfilling or incineration, of which the latter is a energy-intensive and polluting process. By recycling additive manufacturing metal waste, the material stays within a circular economy for longer. Globe Metals aims to demonstrate the value creation of recycling these waste streams by presenting case examples and by sharing insights on how to optimize in-house processes to unlock the most value for the material. 

Learning Objectives:

  • Understand the environmental and economic benefits of additive metal waste recycling as compared to disposal via landfill or incineration.
  • See real-life examples of converting from disposal to recycling.
  • Understand the shared best practices for additive companies to recover the most value for the materials.
