From the Sector

More than 82 companies, businesses and social organizations – including AkzoNobel – are involved in a major Dutch research program focused on developing new technologies that will help solve some of today’s societal challenges.
 
Seven broad consortia have been established as part of the government-funded “Perspectief” program, with AkzoNobel set to play a leading role in the SusInkCoat project, which will explore how to make inks and coatings more sustainable.

The company will work together with private partners and other societal stakeholders to develop new materials, processes and applications to improve the durability, functionality and recyclability of coatings, thin films and inks. The program, which will run for the next five years, is backed by the Ministry of Economic Affairs and Climate Policy and the Dutch Research Council (NWO).

“Our discussions about collaborating with our SusInkCoat partners have been very positive,” says AkzoNobel’s R&D Director of Scientific Academic Programs, André van Linden, who is also the co-lead of SusInkCoat. “We’re all facing the same societal challenges – how to become more circular – and we’re looking for the same solutions in different application areas. But we’ve never done that together for this specific research topic, so we need an ecosystem to help us solve these challenges.
 
Van Linden adds that the program – one of many R&D projects the company is involved with – will also support AkzoNobel’s ambition to achieve 50% less carbon emissions in its own operations – and across the value chain – by 2030.
 
 “We want to make the recyclability of materials - such as furniture, building materials and steel constructions - easier by introducing functionalities like self-healing, higher durability and triggered release,” he continues. “The more you can leave the materials in their original state, the more sustainably you can operate.”

AkzoNobel will be collaborating with Canon, Evonik, GFB, PTG and RUG Ventures, who together possess extensive knowledge of market demands, supply chains and production processes. All the SusInkCoat partners will also work with academic researchers at several Dutch universities in an effort to identify promising developments that can be commercialized, used for education purposes or for outreach to the public.

Research being conducted by the other six consortia includes investigating methods to make tastier plant-based food; flat optics for more sustainable hi-tech equipment; and cheaper and more accessible medical imaging technology.

Lenzing Group, a global producer of wood-based specialty fibers, is celebrating the 40th anniversary of its biorefinery and co-product brand LENZING™ Acetic Acid Biobased. The brand was first introduced on May 4, 1983, and has since become one of the leading and most trusted biobased acetic acid providers.

Over the past 40 years, LENZING™ Acetic Acid Biobased, which has a reduced carbon footprint that is 85% lower than that of fossil-based acetic acid, has continued to gain trust and support from customers. Specialty chemical company Evonik, and food production company Speyer & Grund Group, have been incorporating LENZING™ Acetic Acid Biobased in the production of their products since 1983. LENZING™ Acetic Acid Biobased has also been in high demand from the hygiene industry during the COVID-19 pandemic as an all-purpose cleaning agent in conventional and green products.

Pioneering a carbon neutral future in the biorefinery segment with a new offering
To mark the important occasion, Lenzing will introduce its first carbon neutral LENZING™ Acetic Acid Biobased to meet the growing sustainability needs of industries which predominately rely on fossil-based materials. Similar to the standard LENZING™ Acetic Acid Biobased, the carbon neutral LENZING™ Acetic Acid Biobased is produced using sustainably sourced beech wood as a universal replacement for non-renewable raw materials such as crude oil. By calculating, reducing and offsetting emissions during production processes, this expansion will create a more sustainable supply chain with highly functional products across various industries. From now on, Lenzing customers across the food, pharmaceutical, cosmetics, chemical and textile industries will be able to choose between carbon neutral and reduced carbon footprint acetic acid products.

Advancing circularity and carbon neutrality through efficient use of valuable resources
Lenzing’s biorefinery concept ensures that 100% of wood components are used to produce pulp for Lenzing’s botanic fibers, biorefinery products, as well as bioenergy, which is used to power Lenzing’s facilities. This makes Lenzing’s biorefinery sites almost fully energy self-sufficient to remain as carbon neutral as possible. To ensure a low carbon footprint, rail transportation is the preferred means for transporting LENZING™ biorefinery products, with trucks being leveraged in regions where rail transportation is not available.

Together with ClimatePartner, a recognized global leader in the design, development, and delivery of corporate climate action programs, Lenzing strives to reduce carbon emissions to net-zero through a mix of higher production efficiencies, use of renewable energy sources, low-carbon materials, and the dedicated support of an external nature-based carbon removal project. For instance, to offset remaining carbon emissions that cannot be reduced, Lenzing works with ClimatePartner to support and finance the switch to biomass as an energy source at a ceramic factory in Kitambar in northeastern Brazil. Using natural waste materials, like coconut shells, as renewable biomass for its energy production, the factory is able to produce roof tiles in a more climate-friendly way while saving on carbon emissions. Besides contributing to the fuel switch, the project also helps to reduce the deforestation rate in Brazil and avoid methane emissions that could result from the uncontrolled rotting of biomass.

The AVK – Industrievereinigung Verstärkte Kunststoffe – has once again presented its Innovation Awards to companies, institutes and their partners. Three composites innovations were recognised in each of the three categories – “Innovative Products/Applications”, “Innovative Processes” and “Research and Science” – at the new event JEC Forum DACH on 23 November 2021, the first edition of which was held in Frankfurt.

“As usual, the submissions included a lot of very interesting and promising products and processes this year. The Innovation Awards highlight the outstanding efficiency, cost-effectiveness and sustainability of fibre-reinforced plastics as well as the companies and institutes operating in the sector,” explains Dr. Elmar Witten, Managing Director of the AVK. The jury of leading experts from the industry honoured the following innovations this year:

Category “Research and Science”
First place in the “Research and Science” category was awarded to the German Aerospace Center (DLR) for its Bondline Control Technology (BCT). This innovative process is used for quality control and assurance of bonded joints. The core element is a porous fabric which is applied to a joining surface using an epoxy adhesive or matrix resin. Peeling away the fabric creates a chemically reactive and undercut surface and can also be used as a test to check adhesion to the substrate. BCT has potential in a variety of possible applications. For example, peel ply can be replaced by BCT fabric to produce composite components with an optimised joining surface. The cost-effective BCT peel test is suitable for coupon testing and process control. In addition, the combined adhesion test and surface pre-treatment can be used for quality assurance of bonded repairs on fibre composite structures.

Second place was taken by the Institute of Textile Technology (ITA) at RWTH Aachen University and its partners AEROVIDE GmbH, Altropol Kunststoff GmbH, Basamentwerke Böcke GmbH, TechnoCarbon Technologies GbR with “StoneBlade – Lightweight construction with granite for the wind industry”. This innovation enables manufacturers to reduce the amount of non-recyclable materials used in rotor blade construction. At the same time, it reduces the weight of these components and improves the mechanical properties relating to the stability of wind turbines. The innovative approach replaces glass-fibre reinforced plastic in the blade components with hard rock – a natural, cost-effective and recyclable lightweight material. The slabs of rock are cut and ground to a thickness of just a few millimetres and embedded in a fibre composite laminate with carbon fibre, which stabilises them for alternating load cases. The pre-stressed material is pressure-stable in the composite and can absorb tensile forces in the event of continuously alternating loads without any loss of stiffness.

Third place went to the Dresden University of Technology – Institute for Lightweight Construction and Plastics Technology (ILK) with its partner Mercedes Benz AG for the interdisciplinary development of a highly integrated inductive charging module for electric vehicles. The ultra-thin charging module was designed to make optimum use of space in the vehicle underbody without reducing ground clearance. An interdisciplinary approach was adopted for the development process. This involved the electrical, mechanical and process characterisation of high-frequency Litz wires, ferromagnetic foil and metal wire cloth as well as the creation of a simulation model. The result is a demonstrator for a charging system with a structural height of 15 mm and a total weight of 8 kg. It achieves a transmission efficiency of up to 92 percent at 7.2 kW nominal power and active air cooling. The hardware demonstrator was fabricated in a 3-step process using RTM and VARI techniques.

Im Jahr 1984 gelang es zum ersten Mal überhaupt, aus dem Hochleistungskunststoff Polyimid Fasern zu spinnen. Die damalige Innovation hat Evonik in seinem Produktnamen P84® verewigt, der seitdem für hochtemperaturbeständige Fasern für anspruchsvolle industrielle Anwendungen steht. Das Spezialchemieunternehmen feierte das Jubiläum auf der Techtextil vom 14.-17. Mai in Frankfurt am Main.

„Unsere hervorragenden Hochleistungsfasern erobern selbst 35 Jahre nach deren Entwicklung neue attraktive Märkte“, sagte Jean-Marc Chassagne, Geschäftsführer der Evonik Fibres GmbH. „Wir haben über die Jahre die Polyimidfaser-Chemie aus Österreich konsequent zu einem weltweiten Qualitätsstandard in einer Vielzahl von Anwendungen erfolgreich etabliert.“

Dank der jahrzehntelangen Erfahrung in Polymer-Design ist es Evonik nun gelungen, eine neue Generation von Polyimidfasern zu entwickeln, die die steigenden Ansprüche der Industrie erfüllen. Das neue Produkt überzeugt durch seine verbesserte mechanische Stabilität bei dauerhafter Betriebstemperatur. Evonik wird die neue Faser demnächst kommerziell auf den Markt bringen.
