Recyclable materials

admin 29/09/2022

Fiskars launched a new version of its classic scissors in 2020. The new scissors are fully recyclable. They are 80% recycled material and 13% cellulose fiber. To recycle the scissors, the user must send them to the Fiskars Billnäs factory. There, the scissors are taken apart and the materials are sent to subcontractors for refinement. The renewed materials are then brough back to Fiskars and used to make new recycled scissors.

  1. What materials could you replace with recyclable ones in your product?
  2. How could you use recyclable materials in production?
  3. How could you make it easy to recycle a product?

Key phenomenon

admin 29/09/2022

Valmet’s Metal Belt calender project aimed to reduce stiffness loss in paper after calendering. At the start, the inventor studied the physics of the calendering process. They realized that the duration of heat treatment was a key parameter. In existing calenders, heat treatment lasted only a few milliseconds. Some niche solutions enabled longer heat treatment, but only at slow production speeds. Thus, the project turned its focus on improving heat conduction without slowing the production speed.

  1. What are the key parameters and relationships in your product?
