VTT launches initiative for sustainable fibre-based products

With the continued growth of, for example, global e-commerce, the demand for various fibre-based packaging solutions is projected to grow 5–10 per cent annually, according to data from Statista Market Insights and eMarketer. As such, there is a need to develop scalable, high-quality packaging that is easy to recycle while simultaneously significantly reducing carbon footprint. Within nonwovens, used in napkins and wipes for example, VTT expects a strong shift from traditional products that contain plastic to cellulose-based products.

With a budget of around €20 million ($22 million) over the next four years, the initiative consists of several projects and will establish a new innovative open-access pilot line in Jyväskylä, Finland. The collaborative research aims at developing and testing commercially viable, sustainable alternatives for cardboard packaging, hygiene products, and nonwoven fabrics.

“This new initiative is a pivotal step towards more sustainable and competitive fibre-based products, and has the potential for great impact, thanks to more than 50 industrial partners. We are excited about the prospect of 1:1 commercial projects with companies, driving innovation in energy-efficient paper board production. VTT’s purpose is to bring together people, business, science and technology, paving the way to a sustainable future. The Energy First theme aims to do just that,” said Atte Virtanen, vice president, Biomaterial Processing and Products at VTT.

The forest industry faces new challenges, including the rising cost of energy and fibrewood scarcity. The Energy First theme seeks to overcome these hindrances to sustainable products by developing a manufacturing process with minimal water and energy usage. Preliminary estimates by VTT’s scientists suggest that the new manufacturing process will provide a potential reduction of up to 90 per cent in water consumption and a significant decrease in carbon emissions. Overall, the goal is to reduce energy consumption by up to 50 per cent.

Products manufactured with the new process are designed to be compatible with existing recycling methods. Furthermore, fibre-based packaging is produced in a way that makes it a sustainable alternative to reusable packaging. The planned EU packaging and packaging directive requires that both the raw material and the manufacturing process are sustainable, and recyclable bio-based packaging solutions will have to undergo a sustainability assessment.

In addition to reducing water and energy consumption, the project seeks to redefine the forest industry's environmental impact and enhance the competitiveness of fibre-based products. For example, by making the products lighter, more products could be produced for consumer use from the same amount of wood, which improves resource efficiency.

"The Energy First Consortium project has several captivating work packages that align closely with Valmet’s current research and development objectives. Energy efficiency, investing in novel 3D fibre-based structures, and the strength of fibre products are closely aligned with Valmet’s current research and development objectives. The programme’s global collaboration network ensures that any intriguing project findings can be swiftly implemented in practice,” said Sampo Immonen, R&D director, Valmet.

The equipment for the pilot project will be supplied by Anpap Oy. Anpap designs, manufactures and supplies airlaid technology and machinery.

“We feel that the Energy First project is one of the first steps in unlocking the full potential of airlaid technology in sustainable single-use and durable product categories. Anpap has set the benchmark for the airlaid industry for the past 40 years, and we have a strong commitment to keep developing the technology to enable the transition to next-generation sustainable products. Compared to wetlaid, airlaid web forming is flexible and consumes dramatically less natural resources, such as water, which reduces the environmental impact of manufacturing and while satisfying the needs of consumers,” said Tuukka Vihtakari, CTO, Anpap.

The initiative is funded by EU, ERDF, VTT and the collaborating companies. The consortium is also actively engaging in EU projects, such as EU SteamDry, with a total budget of €9.84 million ($11.01 million) over 3.5 years. VTT will actively continue developing new projects as a part of the initiative including bilateral cooperation with industrial partners.
