Ecological processing and outcome

Lunawood is a pioneer and an expert in modern wood modification thanks to its enhancing of wood’s natural properties, while respecting and preserving the environment in the thermal modification process. Nordic Lunawood Thermowood® is a natural material produced with heat and steam only – and without chemicals. We produce trademarked products using a patented and annually audited process.

The International Thermowood Association (ITWA) supervises its member companies’ pro­duction and quality control processes. This supervision is conducted by Finotrol Oy as an independent third party. Based on Finotrol audits, Lunawood has the right to use the Thermowood® trademark.

In the patented thermal modification process, we transfer from Nordic pine and spruce without any toxics or chemicals Thermowood that is long-lasting, dimensionally stable, resistant to decay and resin-free. It can be used inside or outdoors, in any climate.

These properties make Lunawood Thermowood a sustainable and durable choice for facades, solar shades and other exterior applications as well as for interiors.

Circular Economy - By-products as business

Our aim is no wood waste sent to landfill. We have been able to establish a successful business based on the circular economy, even at our own mill in Iisalmi.  One example of this is the production of Lunawood Thermowood Composite TWPC.

The production of Thermowood generates side streams, like planing dust. We use this dust in the production of Lunawood Thermowood Composite TWPC. It contains 65% Thermowood fibres (planing dust) and 20% high-quality Fortum Circo® recycled plastics. Thanks to our side stream, Lunawood Thermowood Composite has the same features and benefits as Lunawood Thermowood, making it the most stable wood composite decking available on the market. It is more resistant to temperature changes than any other composite material and is highly suitable for all weather conditions.

By producing composite decking material from our by-products, we are able to sequester carbon dioxide emissions for a longer time compared to energy use directly or as wood pellets. A certain part of our planing dust is sold for the production of wood pellets.

We are constantly searching for other circular economy solutions and are continuously considering new uses for by-products.
