The intensive pressure on the world’s fossil resources and an increasing environmental awareness has resulted in a growing interest in renewable routes to polymers/biopolymers throughout the last decade.
The thematic one day conference will focus on how, in the future, we can sustainably acquire raw materials for polymer production whilst reducing the environmental burden. The speakers from KU, DTU, Biopharma DK A/S, Norner AS, Polymerfront AB and Teknologisk Institut will show examples of polymer materials derived from renewable resources.
The speakers will outline some of the biopolymers that are commercially available today, others that are on the way to the market and suggestions as to what will happen in the future. The day will provide an insight into what properties we can expect from polymers based on renewable resources.
The talks will present technologies that use biomass for polymer manufacturing, both direct extraction of polymers, production of polymers by fermentation as well as manufacturing of monomers from biomass. A novel approach involving the use of CO2 as feed stock in polymer production will also be presented.
The thematic one day conference will be held by PTS in the Conference Room, Building 1 at the Danish Technological Institute in Taastrup.
The conference language will be a mix of Danish and English.

10.00 Hvorfor vælge biopolymerer?
Jesper Bøgelund, Danish Technological Institute
I den brede offentlighed anses plast af mange for at være et miljømæssigt dårligt materiale, fordi det forurener, er baseret på fossile ressourcer og er ikke-nedbrydeligt i naturen. Nye biopolymerer vinder frem på deres miljøprofiler, men er ofte hæmmet af utilstrækkelige termisk-mekaniske egenskaber. Vi ser nærmere på nuværende og kommende biopolymerer og deres potentielle anvendelsesområder.
11.00 Strategies for extraction and delivery of added value non-cellulose poly- and oligo- saccharides from cereal residues
John Mark Lawther, Danish Technological Institute
Cereal (grass) crops offer a range of non-cellulose and non-starch polysaccharides, mainly classed as hemicelluloses or “soluble fibres”. These are present in both the seeds (ie cereal grains) and the straws.
The bran components of the common grains: wheat, rye, barley and oats are rich sources of relatively high DP Arabinoxylans (linear and branched) and high DP (10,000 -15,000) linear beta glucans. These polymers have a range of interesting gelling, emulsifying and film-forming properties, as well as being nutraceuticals.
Unlike in woods, grass stems are not so heavily lignified and the lignins are not so condensed, meaning that the hemicelluloses in straws can also be extracted relatively easily and in undegraded forms as compared to those emanating from wood. These are predominantly xylans / arabinoxylans. Such polymers have potentially interesting (as yet unharnessed) properties.
The talk will address methods and techniques to extract and produce such undegraded hemicellulosic polysaccharides from cereal residues and highlight potential application areas for the materials.
11.40 Development of Bacillus derived hyaluronic acid and introduction to Novozymes activities within biochemicals
Manager, Application Development Birgitte Mølholm Malle, Novozymes Biopharma DK A/S
The development of a new hyaluronic acid derived from fermentation of bacillus subtilis for biomedical and pharmaceutical applications will be presented. The unique properties of bacillus derived hyaluronic acid as: purity, consistency and product performance will be outlined. In addition, Novozymes’ biochemicals projects based on metabolic engineering in collaboration with industrial partners will be introduced.Fermentation to a polymer – Hyaluronic acid
13.20 FDCA as a renewable substitute for TPA in polymers
Associate Professor Anders Riisager, Danish Technical University
A chemo-enzymatic process for making the renewable monomer, furan-2,5-dicarboxylic acid (FDCA), from glucose has been developed. FDCA can substitute terephtalic acid (TPA) directly in current polymer products.
14.00 From CO2 to Polymer
Advisor/Business Development Manager Morten Augestad, Norner AS
CO2 can be seen upon as a carbon source for future polymers. Norner has by a catalytic process polymerised CO2 into polymers useful in a variety of applications which include plastics applications like packaging and articles as well as polymers used by the polymer industry like polyurethanes and coatings.
15.00 Bio sourced Green polymers now in the market!
Bjarne Högström, Polymerfront AB (agent for FKUR bio material i Europa)
15:40 Properties of plasticized composite films preparedfrom nanofibrillated cellulose and birch wood xylan
Dr. Natanya Hansen
Xylans, an important sub-class of hemicelluloses, represent a largely untapped resource for new renewable materials derived from biomass. Birch wood xylan was combined with nanofibrillated cellulose (NFC) and films were cast with and without glycerol, sorbitol or methoxypolyethylene glycol (MPEG) as plasticizers. The generated films were studied by optical and scanning electron microscope, and mechanical as well as permeability properties were investigated.
