Water taken from surface waters
Metsä Wood Kerto LVL and plywood mills are located in Northern Europe, which is one of the world’s most water-rich regions. The company does not source any water from areas with high or extremely high water stress (WRI Aqueduct Water Risk Atlas). All the process water is taken from surface waters. Our operations do not prevent or weaken any other parties’ access to water, for example agriculture. Metsä Wood UK mills do not use any process water.
Nevertheless, we are continuously seeking new ways to minimise the use of fresh water in our processes – for example, by recycling our process waters effectively and by using the best available technology. In addition, recycled process water is used to recover the heat created in the production process. These actions minimise our wastewater and air emissions and save energy, thereby reducing impacts on the climate.
Metsä Wood has also launched a project to monitor the water balance of mills to find new ways to reuse and recycle water.
Using water resources responsibly and efficiently
Metsä Wood uses water for log soaking, cooling process machinery, adhesive preparation and in smaller quantities to create steam for thermal energy production.
Soaking in warm water is a pre-treatment for logs before the peeling process. It ensures high veneer quality with good surface properties. High-quality veneers are essential to achieve the final product’s high bonding quality and good surface properties. In addition, the soaking ensures high yield and thus enables resource-efficient raw material use. Soaking water is heated by the recovered heat from the production process and power plant.
Process water is circulated in the production process as long as possible. After use, the process water is cleaned thoroughly before it is returned to nature.
A large portion of the surface water is used for cooling machinery. As the cooling water runs in a separate system, there is no need to clean it after use.
