Cellulose Foam

A novel low-density cellulose pulp material

Together, Apple and RISE have been  making significant progress toward developing a pulp-based replacement for polymeric foams in cushioning applications, a first step in enabling a sustainable and low-carbon future.

When setting out to replace polymeric foams with a wood pulp-based material, there were basic performance requirements formulated:

1. The pulp content should be sufficiently high enough that the material composition could be considered equivalent to paper or board.

2. The material should be fully compatible with the existing recycling streams for paperbased packaging, e.g., re-pulpable, non-contaminating

3. The material should not bond or in some other way remove the fibres from circulating in the fibre processing and recycling cycle.

4. The manufacturing method should be scalable to production of commercially relevant quantities.

5. The ability to mould, cut, form, or assemble the material into different shapes to enable the conversion of the material into shapes and designs useful for the packaging industry.

To accelerate progress and shorten time to market, we are inviting partners to build on our work and develop the material toward different applications.
