Recycled leather is made from the leftovers from shoe and bag manufacturers. Leather strips are first ground into fine leather pulp and mixed with a binding agent. The pulp is then pressed into a recycled leather sheet. Brightly coloured leathers have a colour coating, but natural brown and grey shades are used without such a finish.
Recycled cardboard is made from 100% waste paper, with low use of energy and water in the manufacturing process. The material has been granted the Blue Angel ecolabel, the oldest international environmental label.
Finnish birch plywood is used for instance on notebook covers. Laser cut designs can be used to decorate the surface.
Cork is a versatile, natural and renewable material. Many of the familiar Private Case products are now also available with a cork surface.
