    The production of electrical insulation components with cellulose as the raw material is based on an established technology. However, there is room for improvement in the current manufacturing as it is manual, and thus labour-intensive and slow. In addition, utilization of raw materials and energy are not optimal. These challenges will be tackled in a recently started EU-funded NOVUM project, aiming at development of pilot line based on novel manufacturing technologies for cellulose-based electrical insulation components. The new pilot line will target at rapid, automated and design-driven production of the components as well as significant efficiency improvement, higher productivity and flexibility, while achieving lower operational costs compared to the current technology. In addition, increased resource efficiency is expected, including reduction in labour time, waste generation and energy consumption. Besides technical feasibility, the end user requirements as well as economic, social and environmental impacts, including circular economy considerations will be taken into account.
    NOVUM focuses on three technologies for processing of cellulose-based materials: 3D printing, also known as additive manufacturing, foam forming and thermoforming. Cellulose material development will take place simultaneously to the process development to take into account the requirements of the different processing technologies, such as the thermoplastic features needed for 3D printing, as well as the operational requirements for electrical insulation components.
    In this presentation, the idea behind NOVUM will be discussed. Progress to-date will also be outlined, the first actions focusing on cellulose material and process development and finding out the end user requirements.
