Energy efficiency
All Metsä Group’s production units are overseen by an energy efficiency manager and a management system that complies with the ISO 50001 standard.
Investments drive energy efficiency forward in leaps. Key investments in recent years to increase energy efficiency include, for example, new Kemi bioproduct mill, development program of the Kemi board mill and new steam turbine and the associated generator cooling water recovery at Kyro board mill. The positive effects of the new capacity on energy efficiency have not yet been realized in the sawmill, pulp and board businesses due to the ramp-up phase in production, production restrictions due to weak demand and the political strikes at the beginning of 2024.
Above all, results are achieved by continuously developing operations in the daily routines of mills. Energy efficiency measures are reported annually. In 2024, a total of about 60 energy efficiency measures were reported, of which technical changes to improve energy efficiency were made in several mills.
Fossil-free energy
In recent years, the key investments for phasing out the use of fossil energy in production have been the Kemi bioproduct mill, the renewal of the Husum pulp mill, including matters such as the renewals of the recovery boiler and turbine, the renewal of the turbine at the Kyro board mill, the renewal of the folding boxboard machine at Simpele, and the Mariestad tissue paper mill’s renewal and expansion.
Logistics emissions
Emissions are reduced by replacing fossil fuels in transport with fossil-free alternatives. In addition, logistics emissions are continuously reduced through efficient route planning, minimizing transport distances and optimising filling rates.
To achieve the goal, joint emission reduction targets have been agreed with logistics suppliers, such as VR, Royal Wagenborg and Navalis Shipping.
Mechanical wood products
Wood products are versatile for various long-term uses, such as construction. The carbon stored in wood products acts as an artificial carbon store as long as the material is in use. Light, strong and uniform quality wood products are also excellently suited for element production that improves the efficiency of construction, as well as for hybrid construction that utilizes different building materials. The production capacity of wood products is increased at the new Äänekoski Kerto LVL mill and by optimizing the production of the Rauma sawmill.
Metrics by the end of 2030:
10 units improvement in energy efficiency from 2018 level
0 tonnes of fossil carbon dioxide emissions (Scopes 1 and 2, market-based)
-30%/tkm Greenhouse gas emissions from logistics purchased by Metsä Group from 2022 level (Scope 3, category 4)
+ 30% mechanical wood products from 2018 level
