Waste and by-products
E S G
We invest in resource efficiency so that there is no waste in pulp and board produc- tion. In this way, we reduce waste.
Indicators and progress
In 2022, we used 99.9% (99.8) of our side streams: 55% were reused as materials, and 45% in energy production.
We aim to make 100% use of all production side streams to ensure our processes do not generate any landfill waste after 2030.

Our operations
Waste and by-products Our production side streams consist of by-products generated in our production, including ash used as fertiliser and recov- ered lime fractions, as well as process waste such as green liquor dregs and other types of sludge. Our operations also generate hazardous waste and municipal and construction waste. We improve our recovery methods continuously, so as not to generate waste in the production of pulp and paperboard. We are also seeking new ways to reuse production side streams and use organic waste for energy production. Our biggest challenge is to find applications for the green liquor dregs generated in pulp production, and we are actively exploring solutions for its utilisation. In 2022, our operations generated a total of 36,063 tonnes of by-products and 134,587 tonnes of waste. Our target of using 100% of our production side streams covers all by-prod- ucts and 96.4% of non-hazardous waste in 2022.
