The Vox chain creates sustainable co-development through a common economic ecosystem. The project takes place against the background of previous work on organizing and developing the Vox chain into a stable base, which is now being taken further towards co-developing in a more structured way. The work takes place horizontally, with developed methodology, where groups of companies develop and innovate new value chains and solutions to enable sustainable forestry, which in turn enables the supply of high-quality raw materials to the Vox chain. The main focus of the project is to co-develop products, services and a digital support system for member companies. The project uses a symbiotic relationship between key actors for development towards a circular economy. A stronger sustainable economic ecosystem is the goal of the project, with more companies as members. The effect for the Vox chain as an association should be that own revenues enable an economically robust association, with the ability to drive continued development.
