Purpose and goal

The purpose of this project is to scale up the process developed in the pre-study to investigate if it is suitable for industrial-size production with different kinds of side streams from the forrest industry as raw material, to optimize the characteristics of the resulting PLA, and through a system analysis find out how sustainable the process is. Additionally, a widened and more in-depth market analysis will find price points and volumes for the product. Finally, the circular business modell will be developed to also cover residue streams from other plastic products than 3D filament.

Expected results and effects

The effects this project is aiming at contributing to is: -Replace the black carbon atom with the green in plastic materials -Recycle side streams/bi-products which are burnt today from swedish forrest-/paper mass industry -Connect the circulation of plastic materials through new business models and the cooperation between producers and users -Increase the competitiveness of the Swedish forrest-, chemical- and material industry Expected result is a sustainable process for making the greenest bio-plastics on the market for 3D printing and by extension other applications.

Planned approach and implementation

The initial work packages consists of scaling up the lactate production process in bigger bio-reactors and simultaneously investigate the difference between different raw materials from the forrest industry while doing so. Parallel to this a system analysis will be conducted to investigate the sustainability. Subsequently, the lactate will be polymerized, compounded and tested in different applications. A widened and more in-depth market analysis will then look at other applications for the product and other industries for the circular business model, including prices.
