Biochemicals & Biomaterials: Transforming Wood into Sustainable Solutions

Utilizing Our Resources and Expertise

The world is transitioning away from the dependence on fossil fuel-based products towards the incorporation of the infinite possibilities offered by bio-based products. This will require the replacement of non-renewable materials such as chemicals, plastics, and fossil fuels. We believe that long-term, sustainable wood resources will have an important role to play in this evolution. Wood extractives are biodegradable, carbon-friendly, and generally not recyclable. Wood contains many of the building block chemicals that are found in fossil fuels. We believe that biochemicals will become an increasingly important alternative to petroleum-based fuels, aromatics, food additives, fragrances, and medicinal applications.

We believe that Mercer is well-positioned to leverage our experience and expertise in our aim for the full utilization of our raw material inputs, and in recent years have been expanding our product mix to include biochemicals and biomaterials. We are engaged in a number of initiatives focused on developing innovative, new products including derivatives from our kraft pulping process, as well as stand-alone extractive facilities.

Our Utilization

  • Lignin: The most prevalent bio-polymer on earth

    Located at the Mercer Rosenthal pulp mill, our Mercer Lignin Center is a specialized plant extracting up to 1,000 kilograms of high-quality lignin following the Lignoboost process. Processing a steady blend of softwood species, the resulting lignin offers superior consistency and homogeneity, which turns it into a preferred material for functionalization and further refinement. – The center is equipped with modern storage facilities, control rooms, and laboratories and is seamlessly integrated into the pulp mill for optimal efficiency. The lignin center start-up represents the first step for various products and further processes to follow suit.

    What is Lignin and Why is it Important?

    Lignin, a natural polymer in plant cell walls, has been traditionally underrated. At Mercer, we harness lignin’s largely untapped potential, refining it into valuable aromatic compounds and chemical building blocks. These offer a wide variety of applications—ranging from the production of plastics, paints, and green asphalt binders, over carbon fibres, and biogenic battery materials to cosmetics and functional fillers.

    Our Collaborative Approach

    Mercer’s commitment to innovation builds on strong partnerships with academic institutions, research organizations, and industry leaders. These collaborations are central to exploring and developing diverse applications for lignin-based materials with short lead times.

    Resource and Environmental Impact

    The Mercer Lignin Center doesn’t just signify a milestone for us; it represents our next contribution to support the global push toward a sustainable and circular bioeconomy. Our Commitment to Sustainability

    The Mercer Lignin Center reflects our unwavering commitment to a sustainable and circular economy. We continually invest in new technologies and processes to reduce environmental impact and maximize the use of natural resources.

  • Tall Oil: A Clean, Renewable Alternative

    Along with producing energy from the biomass and chemical recovery process at our pulp mills, we produce an environmentally friendly alternative to some types of petrochemicals: tall oil. The resins contained in coniferous wood store nutrients and act as a source of protection. In our production process, the resin forms soap together with sodium hydroxide, which we separate and then refine to tall oil.

    We operate tall oil facilities at our Stendal and Rosenthal mills in Germany and sell to customers who utilize it as an alternative to petroleum-based fuels. Tall oil has a similar structure to crude oil and is a product made from one hundred percent renewable resources. Currently, the European Union is working toward implementing more stringent carbon regulations, making for more favourable markets for the sale of bio-based fuel products like tall oil.


  • Turpentine: An Indispensable Material

    Another sustainable extractive of our kraft mill process is turpentine. Anyone who has smelled turpentine in its industrial form might have been surprised that this substance – despite its intense odour – is indispensable to producers of fragrances that are used to scent products such as perfumes, deodorants, and detergents.

  • Cellulose Filaments: Unlocking the Foundations of Nature’s Elements

    Through our joint-venture company, Performance BioFilaments, we are in the process of developing commercial applications for cellulose filaments. Cellulose filaments can be used in a wide range of applications, including as a reinforcement agent or a rheology modifier. Industries that can benefit from this technology range from manufacturing, construction, and consumer products. 

    Cellulose filaments can result in lighter-weight materials and more advanced filtration systems. They are differentiated from other cellulose products by their unique aspect ratio and particle size. The material is a ribbon-like form of cellulose that is very long and thin.

  • Sandalwood Oil: Essential for a Variety of Needs

    With our acquisition of the Australia-based Sandalwood producer Santanol, we have begun producing and supplying ethical, sustainable, and reliable Australian-grown Indian Santalum Album oil and products. Sandalwood oil is a foundational essential oil used in fragrances, aromatherapy, cosmetics, and spiritual events. Recently, this material has become scarce, as illegal harvesting has eliminated many of its natural sources.

    Historically, much of the world’s supply of Sandalwood oil has come from unethical, undocumented sources. We are proud to be one of the few large commercial, plantation-based operators offering a future ethical supply of Santalum Album oil. We own and operate 2,500 hectares of sustainable plantations and utilize modern harvesting, processing, oil distillation, and refinery operations in Western Australia.

    Our plantations range in age from 1 to 14 years, with 15 years being the optimal harvest age. We have successfully secured a supply of Santalum Album and Spicatum Album wood from neighbouring plantations, allowing us to offer Sandalwood oils to global markets.
