Metsä Tissue investigated the carbon footprint of toilet paper: high-quality and soft tissue paper is also environmentally friendly

Metsä Tissue has calculated the carbon footprint of toilet paper in its eight European mills, and explored also the differences in the footprints of toilet papers made of fresh and recycled fibres. The results for the products analysed by the company indicate that a roll of toilet paper made of fresh fibre has a carbon footprint that is approximately one fifth smaller than a roll made of recycled fibre.

Metsä Tissue is one of Europe’s largest tissue paper producers, having production in five countries at eight tissue paper mills, producing products from both fresh and recycled fibres. Fresh fibre based tissue papers and their production close to the markets are key elements of the company’s strategy and the use of fresh fibres in Metsä Tissue’s production will continue to increase. Currently, fresh fibres account for around half of the raw material.

“Our carbon footprint analysis was inspired partly by the fact that products made of recycled fibre are often considered a better alternative for the environment, and partly by the increasing challenges in availability and quality of recycled raw material. The biggest differences in the carbon footprints arise from the amount of energy and water needed to purify recycled fibre. To be suitable for hygiene use and food contact, recycled fibre requires effective purification, while fresh fibre is naturally suitable for hygiene use,” says Johanna Kesti, Senior Vice President, Marketing, Communications and Sustainability, at Metsä Tissue.

The carbon footprint analysis offers positive news to tissue paper consumers and producers. The average carbon footprint of tissue papers produced at Metsä Tissue’s mills was 1.4 t CO2 e per tonne of paper. The average European consumes around 12.8 kg of toilet paper a year, which is equivalent to approximately 17.92 kg of CO2. In turn, this corresponds to only around 0.27% of each European’s overall annual carbon footprint. When we use premium fresh fibre based products for hygiene purposes, we create a smaller carbon footprint than when using products made of recycled fibre. Because of its declining availability, recycled fibre will in the future be used in solutions that have lower hygiene and quality requirements than tissue papers, where material yield is higher and where the fibres stay longer in circulation. These include for example transport cardboard packaging.

“Fresh fibre is the hygiene material of the future. By using fresh-fibre products, consumers get sustainably produced tissues with high quality. The production of fresh-fibre paper consumes less energy and water at the tissue mill, and more than 90 per cent of the raw material can be utilised. The use of recycled fibre is less efficient, as only around 60 per cent of the raw material ends up in hygienic tissues and the rest is waste that needs to be processed. In other words, a responsible tissue consumer does not need to compromise on pleasant quality, product safety or sustainability,” Kesti adds.

The EU’s product environmental footprint category rules (PEFCR) were used in the carbon footprint study to calculate the global warming potential (GWP) of base paper production. Product calculations were performed by AFRY in accordance with the ISO 14067:2018 standard and based on the data supplied by Metsä Tissue’s mills.
