The term “biochemicals” is not defined precisely. We define it as a bio-based chemicals that are deriving from sustainable, renewable and carbon neutral feedstocks.
UPM is currently running a basic engineering study to evaluate the possibility to build an industrial scale biorefinery in Germany to produce renewable glycols including bio-monoethylene glycol (bMEG), bio-monopropylene glycol (bMPG) and lignin based on sustainable woody biomass.
UPM’s bMEG and bMPG have exactly the same molecular structure as conventional glycols produced from fossil feedstocks. Therefore, they could be used as drop-in alternatives for all applications where today petrochemical based MEG or MPG is used.
The main advantage would be that customers would not need to compromise on processability, product quality or recyclability to benefit from the improved carbon footprint of UPM’s bio-based glycols.
MEG is a key raw material for polyesters used for textiles, bottles and packaging materials. It is also main component in deicing fluids and coolants. MPG is typically used in composites, pharma, cosmetics and within the food and feed industry as well as a wide range of technical fluids.
Today, many other bio-based chemicals are based on so called first generation feedstocks like corn or sugarcane. Wood has several advantages compared to first generation feedstocks, for example it does not compete with food production and usually does not contain GMO.
Wood is UPM's most important raw material and we are committed to forest management and forest harvesting practices based on the internationally accepted principles of sustainable forest management. Moreover, we plant over 50 000 000 seedlings annually.
UPM monitors the origin of wood to ensure it is sustainably and legally sourced. Forest certification is an excellent tool to promote sustainable forestry. Eighty-five percent of all wood supplies are currently certified and UPM has set the goal to have all wood supplies certified by 2030. Already now, 100 percent of wood supplies to UPM are covered by third-party-audited chains of custody.
Lignin can be found in the cell walls of all plants and it is one of the most abundant biopolymers on Earth. Lignin is nature’s own “glue” due to its polymeric nature and its richness in functional groups.
Currently, kraft lignin and lignosulphonate are available in industrial scale. UPM BioPiva is kraft lignin originating from pulping processes. Unlike lignosulfonate it is not readily water soluble.
In nature lignin provides strength and protects plants against UV irradiation as well as fungal and bacterial attack. Due to these properties, lignin can be used in various applications. For example, it replaces fossil phenol and formaldehyde in phenolic resins. In other polymer systems, it can be used as a structural component as well as a functional filler.
In addition to high quality UPM BioPiva lignin, we also provide expertise and customer support for developing new lignin applications.
Lignin is cost effective compared to many fossil alternatives.
Lignin is produced in large quantities in industrial processes and from consistent raw material streams. UPM has also tight quality control schemes in place for its lignin products.
