Launch webinar – Ash to assets

Have you ever wondered about the untapped potential hidden in everyday by-products? At Holmen, one of the biggest sawmill producers in Sweden, we’re diving deep into one specific query: How can we transform wood ash – a by-product from our biofuel boilers created during the heating and drying process of wood – from waste to wonder?

Our mission is clear: to uncover a sustainable, profitable, and either circular or renewable avenue for this ash. Annual wood ash production of Holmen factories is approximately 450 tons. While there’s undeniable value in returning some of it to our forests and land, we believe there’s a world of innovative possibilities out there waiting to be discovered.

Register and join the webinar to hear more on the HolmenHackathon and the state-of-play for wood ash in Sweden and Finland. Registration and programme available at
