- Pre-engineering continues until summer 2026.
- The mill aims to produce 100,000 tonnes of textile fibre annually.
- Production start is expected no earlier than 2029.
- Kuura fibre is made from softwood pulp without fossil fuels.
Project Overview
Metsä Group is advancing the development of its Kuura textile fibre by initiating pre-engineering for its first commercial mill. This phase aims to prepare for industrial production, focusing on creating high-value wood-based products. The Kuura fibre is derived from softwood pulp sourced from Finnish forests.
Timeline and Structure
The pre-engineering phase is set to continue until the summer of 2026. The project comprises four main components: pre-engineering of the mill, development of the Kuura fibre production process, collaboration with customers for market entry, and the application for an environmental permit.
Environmental Impact
Kuura textile fibre is produced without fossil fuels, offering a lower climate impact compared to competing fibres. This is attributed to its integration with Metsä Group’s bioproduct mill, which operates without fossil energy. A recent study supports the fibre's reduced global warming impact when considering life-cycle emissions.
Development Background
In 2020, Metsä Group launched a demo plant in Äänekoski, Finland, marking a significant milestone in textile fibre development. Following modifications in late 2022 and early 2023, testing and development at the demo plant are progressing. A pre-study on the commercial viability of the Kuura mill was conducted, yielding promising results.
Future Prospects
The pre-engineering project aims to gather the necessary information and expertise for potentially launching the Kuura business. If the decision to build the mill is made, it is expected to produce 100,000 tonnes of textile fibre annually, with operations starting in Finland no earlier than 2029.
