Purpose and goal
Trifilon has developed a unique method of producing biocomposite materials with hemp fiber. One goal of the project is to verify that the flax fibers which today are a waste product, can be applied as reinforcement of plastics and thereby further reduce the composite´s environmental impact. Another goal is to verify the use of recycled plastic in Trifilon´s composites, in order to boost the circular economy. The project has been able to verify that both recycled plastic and flax fiber, with the right preparation, are applicable in Trifilon´s biocomposites.
Expected results and effects
The project has resulted in the applicability of flax fiber and recycled plastic in biocomposites being verified. Linseed fiber requires further processing before the raw material can be introduced into Trifilon´s products. Recycled plastic has now been introduced in Trifilon´s products and is currently on the market. Major savings in carbon dioxide emissions have been found by replacing new plastic with recycled plastic based on an LCA study within the project, reviewed by a external party.
Planned approach and implementation
Availability of flax fiber has been analyzed via growers, Växtrådet, Krav and Lantmännen. Availability on RCP. has been performed by seeking out suppliers and testing. Flax fiber was analyzed through different mill steps, Hammarkvarn, Knivkvarn, Stepcleaner in different configurations. Lab cooking has been performed on flax fiber. Analysis of fiber and degree of purity has been performed. Composite samples have been studied through destructive testing, injection molding tests and in several customer applications. The LCA model has been developed and validated by IVL.
