We make more from the tree
More than 100 years of development
A legacy that extends for more than a hundred years, Domjo (then MoDo) started its operations in 1903. The year 2000 became a mile stone in the history of the mill, when the forest company, MoDo sold the mill to a private consortium, and Domsjö Fabriker was created.
The biorefinery Domsjö Fabriker is a pioneer at the forefront of developing alternative ways to refine the wood raw material into products with a strong environmental profile. It is one of the cradles of the Swedish chemical industry, a legacy that we auspiciously carry forward by utilizing as much as possible of the constituents of the wood raw material. Independently as well as in cooperation with partners, we are continuously developing new products for a sustainable society. To put it simply: We make more from the tree!

Domsjo's main product, specialty cellulose is used for a variety of usages including textile material viscose, nonwoven fabrics, tablets for the pharmaceutical industry, thickeners in paints and food, preservatives, sausage casing and cellophane. Its lignin finds application in concrete additives, binding agents in the mineral industry and the animal feed industry and additives for geotechnical drilling. Bioethanol is used in chemical products and motor fuel.
Number of employees: 350 in Sweden + 25 in the Baltic States
Minimum environmental impact
Environmental concerns have been in our focus for many years. Deliberate environmentally sound measures were implemented in both our processes and our waste treatment facilities, which led to a gradual decrease of our impact upon the environment.
Domsjö Fabriker was the first to bleach cellulose to thhighest degree of brightness in a process totally free from the use of chlorine or chlorine dioxide. Nowadays, we are the only plant worldwide that has a closed loop bleaching process with zero emissions. Bleaching residue is burnt and turned into energy used in the process.
In our bio treatment plant bacteria break down the remaining organic matter and biogas is one of the resulting products. The biogas is recovered and used as energy source for the drying of lignin and the generation of electricity and steam.
The above mentioned developments have had a positive impact on the ecology of the waters around the biorefinery. Studies show a great variety of species of fish in the bay, and sea trout swim by the biorefinery up the Moalven river to spawn.
Our unique process
Our process gives us unique possibilities to produce high quality products maintaining a high environmental standard.
The debarked wood is chipped and fed together with the cooking chemicals into the digesters. The bark is burned and recovers energy in the form of steam. After cooking the cellulose is washed, followed by bleaching with hydrogen peroxide in the closed-loop bleaching unit. The bleached cellulose is then dried and delivered in bales. The whole process from log to bale takes approximately
40 hours.
During cooking in the digesters, hemicellulose and lignin is released. The hemicellulose is fermented and distilled into ethanol. The lignin is refined during the cooking process and the subsequent ultrafiltration process into lignosulfonate.
It is then being dried and packed. The cooking chemicals are being recovered and we recover energy in the form of steam that is being used in our processes.
