A sample of paperboard made of mash, grain bark and peat has been produced in Sastamala, southern Finland. The majority of raw material for the board is mash, only 10-15 percent is grain bark and peat together.
The paperboard has been developed by two universities of applied sciences in Lahti and Tampere together with Design Forum Finland. The work is a part of a Hiilinielu Design Studio (Carbon Sink Design Studio) project, which will last until autumn 2017. The Finnish Packaging Association, Design Foundation Finland and the New Tree project are participants as well.
Residues of grain processing create dark, marble-like figures on the board.
It still takes some time to commercialize the production of the board. In order to produce it, an old-fashioned paperboard machine, for example, is needed.
