Paperboard made of fresh fibre is eco-efficient to recycle, and the recovered fibres are suitable for reuse. Mixed with fresh fibres, the recycled fibres can be reused for making board and paper.
However, board and paper are not infinitely recyclable, as fibres eventually lose strength and length after reprocessing for the fourth or fifth time. To keep the recycling loop running, fresh fibres are constantly needed.
As traceability of recycled fibre material is practically impossible, it is best suitable for non-food packaging, where product safety is not crucial.
In addition to board and paper, it is possible to reuse fibres for other purposes, such as building materials and insulants.
