Fortum and Spinnova present a world-first: wheat straw-based clothing

October 22, 2019
Press Release: Spinnova

Fortum, an energy company building new business options in the circular economy, together with sustainable fiber technology company Spinnova, has introduced the first prototype product made using wheat straw in production of highly sustainable textile fiber

Fortum and Spinnova have introduced the first prototype product born out of their joint development of using wheat straw in the production of highly sustainable textile fiber. The showpieces at the Textile Exchange Sustainability Conference in Vancouver included a knitted t-shirt, as well as a jacket and skirt made of a woven fabric on organic cotton warp. The prototype material is unique also due to its extremely low environmental impact from raw material extraction, processing and manufacture, verified by life-cycle analysis (LCA).

“We are very excited to present this revolutionary textile,” said Heli Antila, vice president, Biobased solutions at Fortum. “Wheat straw is mostly discarded or even burned in the fields. As it can now be used in numerous textile applications, this opens up huge possibilities globally. This cooperation is a tangible step towards our strategy to build options for significant new businesses that improve resource efficiency and provide smart solutions for a cleaner world. We would like to invite more key industry players to join us in this journey.”

“We are all very proud of this amazing collaborative accomplishment!” added an enthusiastic Janne Poranen, Spinnova’s CEO. “This was a very fast journey from the first trials to real, appealing fabric materials. This shows that wheat straw-based fiber is well on its way to being a drop-in product of the most sustainable kind.”

The parties announced their partnership earlier this year after testing various biomasses. The showcased straw was first processed with highly sustainable fractionation technology, developed by Fortum’s associate company Chempolis. Spinnova’s technology, presently in a piloting phase, turns microfibrillated cellulose (MFC) directly into fiber mechanically without any dissolving or harmful chemical processes. Fibers of the now-showcased clothing were produced in Spinnova’s pilot facility in Finland, which also means that Spinnova’s technology can be applied to various biomasses without further technology development.

The two companies plan to establish sustainable fiber production in Fortum’s future biorefineries that will use residual biomasses such as agro waste. The biomass will be processed into materials for bioproducts of lignocellulosic origin, as well as cellulosic products. The refineries will be based on fractionation technology, enabling highly resource-efficient utilization of wheat straw and resulting in significantly lower environmental impact compared to other processing technologies.

Plastic Free World Conference & Expo 2020 will take place at Cologne Messe, Germany, on Tuesday 16 June and Wednesday 17 June. To register for this highly focused, solutions-driven event, please click here. For sponsorship and exhibition opportunities, please email peter@trans-globalevents.com
