Oat hull as packaging material

Oat hull gets a new life in packaging

Food production creates biomass as side streams that could be used as a valuable raw material in the manufacture of products instead of burning and composting.

 

The “HerääPahvi!” project presents e.g. utilization of oat hulls in the manufacture of packaging materials. For example, oat bread could be sold in packages with oat hull, or to utilize tomato or cucumber stalks in vegetable packages.

How it works in practice

The wordless story of the circular economy works in the packaging we have made. Packages that utilize side-stream materials stand out from the traditional ones with their special appearance. The consumer sees with his own eyes and in this case even feels with his own fingers the hull fraction on the surface of the paper. This side stream material that would otherwise go through incineration gets many lives in the package.

With media and design experts, we have made stories around the product and designed various prototypes to waken up both consumers and producers!

Economic opportunities and broarder social significance

Products that utilize oat hull have a social significance when they broadly guide consumer behavior that promotes the circular economy. Utilizing process’ side streams into more valuable end products creates added value for the entire value chain.

We produced paper with a pilot paper machine (Tervakoski Oy), in which part of the softwood pulp was replaced with oat hulls such as they come from the mill (Fazer Mill). Paper bags (Peltolan Pussi Oy) were produced on a production scale and other prototypes on a smaller scale (DS Smith Packaging). Utilizing side streams has commercial potential and increases the value of the brand.
Other information
The “HerääPahvi!” project is a joint project of Tampere University of Applied Sciences, the Natural Resources Center (Luke) and Design Forum Finland, which combines the know-how of creative industries with the bio and circular economy and their latest innovations. The project has received funding from the European Social Fund (ESF). The project will end in December 2020.
