Abstract
A 3D shaped product (20) is formed by hot pressing of an air-laid blank (10) comprising natural fibers at a concentration of at least 70% by weight of the air-laid blank and a thermoplastic polymer binder at a concentration selected within an interval of from 2.5 up to 30% by weight of the air-laid blank. The 3D shaped product (20) is recyclable in a repulping process. At least a part of the thermoplastic polymer binder is water soluble at a repulping temperature of the repulping process. The 3D shaped product (20) are environmentally friendly alternatives to plastic 3D shaped products made by foamed polymers and can be recycled in existing recycling schemes.
