We work for a better climate


Metsä Tissue uses certified management systems to ensure continuous improvement of operations and compliance with the systems’ requirements. All Metsä Tissue’s mills have certified ISO 9001, ISO 14001 and ISO 50001 quality-, environment and energy efficiency standards and almost all have an occupational safety management standards OHSAS 18001 or ISO 45001. Metsä Tissue mills also have chain-of-custody certificates to ensure the traceability of the wood-based raw material. To see all Metsä Tissue's mill specific certificates of ISO, PEFC* and FCS®* read more here and read more about our Metsä Group’s chain-of-custody requirements.

The most significant environmental impacts of our tissue paper production are related to the use of energy and water, as well as the de-inking sludge generated in the recycled fibre purification and de-inking process.


Aiming for fossil-free mills

The environmental sustainability is essential for Metsä Tissue and the entire Metsä Group, and the company’s operations are developed to continuously improve its environmental performance. Energy usage is one of the most important sustainable development topics in Metsä Tissue’s operations. Metsä Tissue, and Metsä Group as a whole, are aiming for fossil free mills by 2030. This means that fossil fuels will no longer be used in production, and thus no fossil fuel-based carbon dioxide emissions would be generated.  Building a biopower plant in Metsä Tissue’s Katrinefors mill area in Sweden in 2018 has changed the energy usage of not only of the mill, but of the entire town of Mariestad. Read more about the biopower plant here.

In 2020, the share of fossil free fuels in Metsä Tissue’s production was 16 per cent. Metsä Tissue has reduced its direct fossil CO2 emissions (Scope 1 and Scope 2) by 29 per cent per product tonne since 2009, equaling around 166 000 fossil CO2 emissions.

Focus on energy efficiency

By the end of 2020 our energy efficiency improvement has been 10.3 per cent since 2009. To keep up the good work we have set a new target, 25 per cent improvement of energy efficiency from 2019 level to 2030.

In 2020 we introduced energy improvements in paper sheet drying by using the newest technology in vacuum system in Krapkowice mill and boosting dewatering in press section in Raubach mill. We also aim to use less energy by increasing efficiency in our paper production process. In papermaking we are focusing on drying hood development and removal of the water from the paper sheet via the newest system technologies. More-over our new pulp stock refining concepts are more energy effective compared to the conventional solutions. Transformation to the best available compressed air technology and air cooling systems are in our roadmaps for 2030. Read more about our energy efficiency actions from Mänttä mill.


Resource efficient production and efficient use of side streams

Water is an important resource for us. We continuously develop water use and efficiency in our processes. During 2020, we used 18.1 m3 of process water per produced ton, and we have reduced it by 14 per cent since 2010. We are continuously making water use more efficient by closing water cycles inside the mills and developing biological wastewater treatment processes. Water circulates in the process numerous times, and it is carefully purified before released as an effluent. Our 2030 target is to reduce the amount of process water used in m3/tonne by 25 per cent from 2018 level.

We strive to utilise all production side streams as efficiently as possible, and our goal is that by 2030 we will make use of all the side streams rather than generating any landfill waste. In 2020, the utilisation rate for side streams was as high as 98 per cent. In the production of hygiene tissue papers, the largest side stream is the de-inking sludge from the cleaning of recycled paper. Currently, de-inking sludge is used both as a raw material and for generating energy. It is used as fibre clay for various purposes, such as raw material for the construction industry and material for the construction of landfill sites and road building. 

At the Mänttä mill, de-inking sludge is pressed into form pellets that are used as fuel for energy production, replacing the use of fossil fuels such as peat. Thanks to this process, the fossil CO2 emissions from the mill area have been reduced by 12,000 tonnes per year.
