Metsä Board Sustainability Review 2023

Fresh fibre paperboards support the circular economy

Metsä Board follows the principles of circular economy by using renewable resources, ensuring efficient and fossil free operations and keeping materials in use and in circulation for as long as possible.

Alternatives to plastics Renewable fresh fibre is our main raw material, and we have a systematic development programme for replacing the remaining fossil-oil- based raw materials still used. Our paperboards, such as the dispersion coated barrier paperboard, help our customers reduce the use of plastics in packaging. Diverse and vibrant forests We are committed to regenerative forestry that enhances biodiversity and strengthens the state of nature. We use only traceable wood of certified or controlled origin. We also ensure that forests grow more than is harvested so that the forests can continue to act as a carbon sink. Forestry operations do not cause deforestation in our wood supply area. Minimising environmental impact We continue to focus on the efficient use of raw materials, water and energy. We follow the environmental impact of all our paperboards with life cycle assessments based on the requirements set out in the ISO 14025 and ISO 14040/14044 standards. The light weight of our paperboards and the high share of fossil free energy used reduce the environmental impact of our paperboards.

With a recycling rate of over 80%, paper and paperboard packaging is the most recycled packaging material in the EU and the US (Source: Eurostat, EPA)

Fresh fibres help maintain the recycling loop

Pure and strong fresh wood fibres improve the quality of fibres in circulation and they can be recycled multiple times. This makes fresh fibre paperboards an excellent material for the circular economy. In addition, they compensate for the materials not returned to circulation. Designed to be recycled All our paperboards are recyclable, depending on the local recycling systems. All Metsä Board paperboards except for the PE coated grades are also certified as industrially compostable in accordance with the DIN EN 13432 and/or ASTM D6400 standards and home compostable in accordance with the NF T 51–800 standard. By joint design guidelines and cross-industry collab- oration, such as 4evergreen alliance, we support the recyclability or compostability of our products after use. Sustainable solutions by cooperation Metsä Board 360 Services help our customers to improve the functionality and recyclability of their packaging, decrease the use of plastics, and reduce raw material use and the environmental impact of the packaging solution. The Excellence Centre in our Äänekoski site provides an inspira- tional co-creation platform for our customers and partners worldwide.

Keep recycling loops going

Renewable wood-based raw material

Circular paperboard solutions

Resource- efficient production

Materials are used in the best possible way

As part of Metsä Group, we use 100% of the sourced wood raw material, and nothing goes to waste. We are also seeking new ways to reuse our production side streams. For example, Soilfood, a Finnish circular economy company, produces wood-based soil improvement fibres from frac- tions produced as side streams at Metsä Board’s board mills.
