In March 2011, the European Commission set a challenging target of an 80% reduction in CO2 emissions by 2050. In November 2011, the Paper Industry launched its own 2050 Roadmap that analysed how to achieve this decarbonisation target, while increasing value in the sector by 50%. One year later, the industry followed up by launching the Two Team Project which brought together the teams that have developed the eight concepts.
In this year-long competition, two teams comprising scientists, companies, suppliers and outsiders worked to identify viable concepts that could help the industry achieve its objectives. Climate Action Commissioner Connie Hedegaard announced the winning team and winning concept from among the eight finalists. She praised the efforts of the sector: “Global markets for resource and energy efficient solutions will grow. CEPI 2050 Roadmap and the ideas prepared in the Two Team Project show that the European Pulp and Paper Industry is ‘technology conscious’ and ready for future challenges. It’s an example to be followed by other sectors.”
The winning concept was announced as “Deep Eutectic Solvents”. It is a brand new technology which, at low temperatures, breaks down biomass into its constituent parts which can then be used in the Paper and Pulp Industries. If utilised at scale, this technology could radically change pulp and paper production around the world and replace some of the most energy-intensive parts of the current process. Deep Eutectic Solvents (DES) have produced remarkable results in laboratory trials, but they will need to be studied and developed further over the coming months and years.
Commenting on the outcome of the competition, Teresa Presas, CEPI Director General, said: “The results are beyond expectations. While we have announced a winner, we are confident that all the shortlisted concepts have an important role to play. We believe the teams have found the key to the largest industrial breakthroughs in decades in our industry. Now policy must be encouraged to support the development of these technologies.”
Teresa Presas went on to say: “Policymakers once thought targets could be met with existing technology and behavioural change. That is wrong. Breakthrough technologies are needed to meet low carbon targets. Investments in innovation need to focus on breakthroughs, not on incremental growth. CEPI’s Two Team Project perfectly illustrates this.”
Little effort is given to developing breakthrough innovations for the manufacturing sectors of tomorrow and industrial and climate policy have left this area untouched.
The Two Team Project went as far as any industry sector can go at organising an open innovation process and providing pre-competitive leads. It is now up to individual companies to take the next step and develop the concepts. This will need new forms of cooperation, and the support of European and national policy makers. The right conditions must be put in place to enable research, pilot demonstration and investments.
The announcement of the winner was followed by a seminar on Thursday 28 November in which the eight finalists all had an opportunity to present their concepts to European Paper Week attendees.
The eight breakthrough technologies are a combination of new ideas and of ideas that work in other sectors, but have never been utilised before in the paper and pulp sector. They include some cutting edge research findings, as well as innovations that have not yet made it to market. The solutions are not only found in technology, but also in new ways of working and even changes to the way production is measured today. More importantly, they can open up entirely new product portfolios for the future.
The eight finalists were:
Deep Eutectic Solvents – the winner
A ground-breaking discovery: Deep Eutectic Solvents (DES) produced by plants, opens the way to produce pulp at low temperatures and at atmospheric pressure. Using DES, any type of biomass could be dissolved into lignin, cellulose and hemicellulose with minimal energy, emissions and residues. They could also be used to recover cellulose from waste and to dissolve ink residues in recovered paper.
Flash Condensing with Steam
Waterless paper production? Very nearly. Largely dry fibres would be blasted into a forming zone with agitated steam, condensing into a web using one-thousandth the volume of water used today.
Steam
Using more energy to use less? You read it right. Using the full power of pure steam for superheated steam drying would save energy, as most of the heat could be recovered and recycled. Steam would then be used as the fibre carrier for making and forming paper.
Supercritical CO2
Neither gas nor liquid but somewhere in between, Supercritical CO2 (scCO2) is widely used in many applications including drying vegetables, fruit and flowers, extracting essential oils or spices, and to dye textiles. Coffee and tea have been decaffeinated with scCO2 since the early 80s. It could be used to dry pulp and paper without the need for heat and steam, and why not dye paper or remove contaminants too?
100% electricity
Shifting pulp and paper production to energy-efficient technologies using electricity, rather than fossil fuel power, to generate heat will cut all CO2 emissions as the power sector shifts to renewable energy. The sector would also provide a buffer and storage capacity to the grid, storing energy as hydrogen or pulp.
DryPulp for cure-formed paper
Imagine a papermaking process that uses no water. This is it. Fibres are treated to protect them from shear, and then suspended in a viscous solution at up to 40% concentration. The solution is then pressed out and the thin sheet cured with a choice of additives to deliver the required end-product.
Functional Surface
The key to unlocking greater added value from fewer resources depends on a shift to producing more lightweight products, and selling surface area and functionality rather than weight. Advances in sheet formation and new cocktails of raw materials will lead the way to the lightweight future.
The Toolbox to replicate
What about the great ideas that never make it? Put together a combination of process, material and equipment innovations as a toolbox of stepping stones to 2050 and the pathway becomes clearer, boosting sector and investor confidence.
