Stora Enso

Problem statement

Providing bio-based solutions from forestry biomass for a range of global industries and applications

Executive summary

Stora Enso is a leading provider of renewable products in packaging, biomaterials, and wooden construction. They operate one of the largest recycled paper mills in Europe, producing 555 000 tonnes of recycled paper each year. Formed fibre products which are manufactured by pressing various wood-based pulps into a three-dimensional shape in a highly automated forming machine. Utilizing their extensive capabilities in fibre-based materials and processes, they concentrate first and foremost on replacing single-use plastic products in high consumption markets. Stora Enso is a leading provider of renewable products in packaging, biomaterials, and wooden construction, and one of the largest private forest owners in the world

Value chain description

Stora Enso’s biorefinery process consists of three different platforms: xylose (C5 sugars), lignin, and cellulose or glucose (C6 sugars). Lignin extracted in such a way has different characteristics to kraft lignin and, therefore offers novel application opportunities including in the automotive and construction industries. Its sustainable extraction process creates a range of fossil-free materials such as specialty pulp grades. Stora Enso’s biorefinery concept also allows for new technologies to extract hemicellulose, sugars, and lignin from a variety of biomass more efficiently. Alongside continued investment in lignin extraction, related areas of development also being considered at the moment include:a) Microfibrillated Cellulose (MFC) – a cellulose material which has different dimensions to conventional pulp. This leads to different properties such as increased viscosity and gelling behaviour., b) Lignin-based products could replace fossil-derived chemicals and materials, c) Biochemicals, including pulp mill by-products and functional chemicals for specialty uses

Market deployment considerations

The paper and packaging market size is estimated at USD 1.14 trillion in 2024, and is expected to reach USD 1.38 trillion by 2029, growing at a CAGR of 3.89% during the forecast period (2024-2029).

Environmental considerations

Stora Enso contributes to the transformation towards a biobased circular economy in three areas where they have the biggest impact and opportunities: climate change, biodiversity, and circularity. With their low-carbon and recyclable fiber-based products, they support their customers in meeting the demand for renewable eco-friendly products

Social Considerations

This project aims to support the development of certain rural areas by using natural resources in a sustainable manner as well as fostering alternative income opportunities for the communities. Part of the project is the afforestation of 20 ha of degraded land. This area surrounds the so called Eco-Social Farm, an institution for people with disabilities. As part of the project, a collaboration with Eco-Social Farm has been set up to employ people who would not have the opportunity to get a job in the normal labor market
