From the Sector

The European Pultrusion Technology Association (EPTA) has published a report from its latest conference, which focuses on advances in sustainability and recycling.

More than 130 professionals from the global pultrusion community gathered at the 16th World Pultrusion Conference in Paris on 5-6 May 2022. Organised by EPTA in collaboration with the American Composites Manufacturers Association (ACMA), the event featured 25 international speakers sharing insight on market trends, developments in materials, processing and simulation technologies, and innovative pultruded applications in key markets such as building and infrastructure, transportation and wind energy.

‘Bio-pultrusion’:  
Composites based on natural fibres offer a number of benefits, including low density and high specific strength, vibration damping, and heat insulation. The German Institutes for Textile and Fiber Research Denkendorf (DITF) are developing pultrusion processes using bio-based resins and natural fibres. Projects include the BioMat Pavilion at the University of Stuttgart, a lightweight structure which combines ‘bamboo-like’ natural fibre-based pultruded profiles with a tensile membrane.

Applications for recycled carbon fibre (rCF):
The use of rCF in composite components has the potential to reduce their cost and carbon footprint. However, it is currently used to a limited extent since manufacturers are uncertain about the technical performance of available rCF products, how to process them, and the actual benefits achievable. Fraunhofer IGCV is partnering with the Institute for Textile Technology (ITA) in the MAI ÖkoCaP project to investigate the technical, ecological and economic benefits of using rCF in different industrial applications. The results will be made available in a web-based app.

Circularity and recycling:
The European Composites Industry Association (EuCIA) is drafting a circularity roadmap for the composites industry. It has collaborated with the European Cement Association (CEMBUREAU) on a position paper for the EU Commission’s Joint Research Centre (JRC) which outlines the benefits of co-processing end-of-life composites in cement manufacturing, a recycling solution that is compliant with the EU’s Waste Framework Directive and in commercial operation in Germany. Initial studies have indicated that co-processing with composites has the potential to reduce the global warming impact of cement manufacture by up to 16%. Technologies to allow recovery of fibre and/or resin from composites are in development but a better understanding of the life cycle assessment (LCA) impact of these processes is essential. EuCIA’s ‘circularity waterfall,’ a proposed priority system for composites circularity, highlights the continued need for co-processing.

Sustainability along the value chain:
Sustainability is essential for the long-term viability of businesses. Resin manufacturer AOC’s actions to improve sustainability include programmes to reduce energy, waste and greenhouse gas emissions from operations, the development of ‘greener’ and low VOC emission resins, ensuring compliance with chemicals legislation such as REACH, and involvement in EuCIA’s waste management initiatives. Its sustainable resins portfolio includes styrene-free and low-styrene formulations and products manufactured using bio-based raw materials and recycled PET.

This collaborative and educational project showcases the use of waste as a resource and prolonging the life of the garment through color. It came to life thanks to key brands who donated items that were then transformed by Officina39’s Recycrom™ applications into a renewed head-to-toe look that was then displayed as an art installation.

What’s the Recipe for change? For Officina39 and Adriana Galijasevic’s Cocircular Lab, this question gives shape to the collaborative and educational project Circular Explorations, specially presented at Amsterdam Denim Days Festival on April 22-23.

Sharing ground values and a common view on the fashion of tomorrow, Officina39, Italian based Chemistry plus Creativity company for the textile sector, joined hands with Adriana Galijasevic’s Cocircular Lab and influential brands to celebrate the importance of an ongoing commitment towards circularity.

Several donated items – overstock, second-grade production or damaged, unsold pieces – were updated with newly developed applications made with Officina39’s Recycrom™, the one-of-a-kind, patented dyestuffs range made from textile waste. This Circular Explorations capsule is displayed at Denim Days Festival as an art installation, not only to dress people but also to get them acquainted with circularity because they are an important player in closing the loop.

The Recipe for change that emerges from this color research is based on important values and keywords:

• Consciousness – awareness of oneself and one's surroundings
• Courage – the mental or moral strength to venture, persevere, and withstand danger, fear, or difficulty.
• Creativity – the power to imagine and produce new possibilities.
• Connection – a relationship in which a person or thing is linked or associated with something else, the act or state of connecting.
• Collaboration – the act of working together for a common goal.

Combined together, they produce CHANGE, which is a driving force for a better tomorrow.

This collaborative and innovative project that addresses circularity is also in direct support of United Nations Sustainable Development Goals, in particular number 12-Responsible Consumption and Production, number 9-Industry innovation & Infrastructure and number 17-Partnership for the Goals.

BB Engineering GmbH (Germany), a subsidiary of Oerlikon Textile, is pleased to announce that Thai Polyester Co., Ltd (Thailand) has placed a major order for four VacuFil systems for recycling bottle flakes with connected direct spinning. The polyester manufacturer, established in 2001 and with an overall annual capacity of 316,800 tons, is one of Thailand’s leading producers and exclusively uses German technology. To this end, the company already operates Oerlikon Barmag and Oerlikon Neumag systems. The BB Engineer-ing VacuFil systems will be deployed to convert existing spinning plant equipment from processing polyester to processing PET bottle flakes without loss of performance.

BB Engineering supplies the complete recycling process – from the drying stage and extrusion, all the way through to the spinning plant-appropriate fine filtration stage. Thanks to decades of experi-ence in spinning plant technology, the German machine construc-tor also provides comprehensive spinning plant know-how and is aware of how the recycling process must be designed to ensure that the product manufactured using the spinning plant ultimately has the right quality. The four new VacuFil systems will be integrated into the existing building infrastructure and process landscape at Thai Polyester, with a total output of approx. 4,000 kg/h. The Vacu-Fil systems will be complemented by BB Engineering 3DD mixers for directly feeding dyes into the recycled melt flow. Commissioning has been scheduled for 2023.

Thai Polyester will be using the new VacuFil systems to manufac-ture its ‘EcoTPC’ recycling-brand yarns. 100% of these polyester yarns are produced from bottle, fiber and yarn waste and are all GRS certified.

• Renewable Carbon Initiative (RCI) published a strategy paper on the defossilisation of the chemical and material industry with eleven policy recommendations

The Renewable Carbon Initiative, an interest group of more than 30 companies from the wide field of the chemical and material value chains, was founded in 2020 to collaboratively enable the chemical and material industries to tackle the challenges in meeting the climate goals set by the European Union and the sustainability expectations held by societies around the globe.

RCI addresses the core of the climate problem: 72% of anthropogenic climate change is caused directly by extracted fossil carbon from the ground. In order to rapidly mitigate climate change and achieve our global ambition for greenhouse gas emission reductions, the inflow of further fossil carbon from the ground into our system must be reduced as quickly as possible and in large scale.

In the energy and transport sector, this means a vigorous and fast expansion of renewable energies, hydrogen and electromobility, the so-called decarbonisation of these sectors. The EU has already started pushing an ambitious agenda in this space and will continue to do so, for instance with the recently released ‘Fit for 55’ package.

However, these policies have so far largely ignored other industries that extract and use fossil carbon. The chemical and material industries have a high demand for carbon and are essentially only possible with carbon-based feedstocks, as most of their products cannot do without carbon. Unlike energy, these sectors cannot be “decarbonised”, as molecules will always need carbon. The equivalent to decarbonisation via renewable energy in the energy sector is the transition to renewable carbon in the chemical and derived materials industries. Both strategies avoid bringing additional fossil carbon from the ground into the cycle and can be summarised under the term “defossilisation”.

To decouple chemistry from fossil carbon, the key question is which non-fossil carbon sources can be used in the future. Rapid developments in biosciences and chemistry have unlocked novel, renewable and increasingly affordable sources of carbon, which provide us with alternative solutions for a more sustainable chemicals and materials sector. These alternative sources are: biomass, utilisation of CO2 and recycling. They are combined under the term “renewable carbon”. When used as a guiding principle, renewable carbon provides a clear goal to work towards with sufficient room to manoeuvre for the whole sector. It enables the industry to think out of the box of established boundaries and stop the influx of additional fossil carbon from the ground.

The systematic change to renewable carbon will not only require significant efforts from industry, but must be supported by policy measures, technology developments and major investments. In order to implement a rapid and high-volume transition away from fossil carbon, and to demonstrate its impact, a supportive policy framework is essential. The emphasis should be put on sourcing carbon responsibly and in a manner that does not adversely impact the wider planetary boundaries nor undermines societal foundations. An overarching carbon management strategy is required that also takes specific regional and application-related features into account, to identify the most sustainable carbon source from the renewable carbon family. This will allow for a proper organisation of the complex transition from today’s fossil carbon from the ground to renewable energy and to renewable carbon across all industrial sectors.

RCI has developed eleven concrete policy recommendations on renewable carbon, carbon management, support for the transformation of the existing chemical infrastructure and the transformation of biofuel plants into chemical suppliers. The policy paper “Renewable Carbon as a Guiding Principle for Sustainable Carbon Cycles” is freely available for download in both a short version and a long version.

• More than 30 leading pioneers of the chemical and material sector welcome the latest political papers from Brussels, Berlin and Düsseldorf

The political situation for renewable carbon from biomass, CO2 and recycling for the defossilisation of the chemical and materials industry has begun to shift fundamentally in Europe. For the first time, important policy papers from Brussels and Germany take into consideration that the term decarbonisation alone is not sufficient, and that there are important industrial sectors with a permanent and even growing carbon demand. Finally, the need for a sustainable coverage of this carbon demand and the realisation of sustainable carbon cycles have been identified on the political stage. They are elemental to the realisation of a sustainable chemical and derived materials industry.

The goal is to create sustainable carbon cycles. This requires comprehensive carbon management of renewable sources, which includes carbon from biomass, carbon from Carbon Capture and Utilisation (CCU) – the industrial use of CO2 as an integral part – as well as mechanical and chemical recycling. And only the use of all alternative carbon streams enables a true decoupling of the chemical and materials sector from additional fossil carbon from the ground. Only in this way can the chemical industry stay the backbone of modern society and transform into a sustainable sector that enables the achievement of global climate goals. The Renewable Carbon Initiative’s (RCI) major aim is to support the smart transition from fossil to renewable carbon: utilising carbon from biomass, CO2 and recycling instead of additional fossil carbon from the ground. This is crucial because 72% of the human-made greenhouse gas emissions are directly linked to additional fossil carbon. The RCI supports all renewable carbon sources available, but the political support is fragmented and differs between carbon from biomass, recycling or carbon capture and utilisation (CCU). Especially CCU has so far not been a strategic objective in the Green Deal and Fit-for-55.

This will change fundamentally with the European Commission's communication paper on “Sustainable Carbon Cycles” published on 15 December. The position in the paper represents an essential step forward that shows embedded carbon has reached the political mainstream – supported by recent opinions from members of the European parliament and also, apparently, by the upcoming IPCC assessment report 6. Now, CCU becomes a recognised and credible solution for sustainable carbon cycles and a potentially sustainable option for the chemical and  material industries. Also, in the political discussions in Brussels, the term “defossilation” is appearing more and more often, complementing or replacing the term decarbonisation in those areas where carbon is indispensable. MEP Maria da Graça Carvahlo is among a number of politicians in Brussels who perceive CCU as an important future industry, putting it on the political map and creating momentum for CCU. This includes the integration of CCU into the new Carbon Removal Regime and the Emission Trading System (ETS).

As the new policy documents are fully in line with the strategy of the RCI, the more than 30 member companies of the initiative are highly supportive of this new development and are ready to support policy-maker with data and detailed suggestions for active support and the realisation of sustainable carbon cycles and a sound carbon management. The recent political papers of relevance are highlighted in the following.

Brussels: Communication paper on “Sustainable Carbon Cycles”
On 15 December, the European Commission has published the communication paper “Sustainable Carbon Cycles” . For the first time, the importance of carbon in different industrial sectors is clearly stated. One of the key statements in the paper is the full recognition of CCU for the first time as a solution for the circular economy, which includes CCU-based fuels as well. The communication paper distinguishes between bio-based CO2, fossil CO2 and CO2 from direct air capture when addressing carbon removal and it also announces detailed monitoring of the different CO2 streams. Not only CCU, but also carbon from the bioeconomy is registered as an important pillar for the future. Here, the term carbon farming has been newly introduced, which refers to improved land management practices that result in an increase of carbon sequestration in living biomass, dead organic matter or soils by enhancing carbon capture or reducing the release of carbon. Even though the list of nature-based carbon storage technologies is non-exhaustive in our view, we strongly support the paper’s idea to deem sustainable land and forest management as a basis for the bioeconomy more important than solely considering land use as a carbon sink. Surprisingly, chemical recycling, which is also an alternative carbon source that substitutes additional fossil carbon from the ground (i.e. carbon from crude oil, natural gas or from coal), is completely absent from the communication paper.

Berlin: Coalition paper of the new German Government: “Dare more progress – alliance for freedom, justice and sustainability”
The whole of Europe is waiting to see how the new German government of Social Democrats, Greens and Liberals will shape the German climate policy. The new reform agenda focuses in particular on solar and wind energy as well as especially hydrogen. Solar energy is to be expanded to 200 GW by 2030 and two percent of the country's land is to be designated for onshore wind energy. A hydrogen grid infrastructure is to be created for green hydrogen, which will form the backbone of the energy system of the future – and is also needed for e-fuels and sustainable chemical industry, a clear commitment to CCU. There is a further focus on the topic of circular economy and recycling. A higher recycling quota and a product-specific minimum quota for the use of recyclates and secondary raw materials should be established at European level. In the coalition paper, there is also a clear commitment to chemical recycling to be found. A significant change for the industry is planned to occur in regards to the so-called “plastic tax” of 80 cents per kilogram of non-recycled plastic packaging. This tax has been implemented by the EU, but most countries are not passing on this tax to the manufacturers and distributors, or only to a limited extent. The new German government now plans to fully transfer this tax over to the industry.

Düsseldorf: Carbon can protect the climate – Carbon Management Strategy North Rhine-Westphalia (NRW)
Lastly, the RCI highly welcomes North Rhine-Westphalia (NRW, Germany) as the first region worldwide to adopt a comprehensive carbon management strategy, a foundation for the transformation from using additional fossil carbon from the ground to the utilisation of renewable carbon from biomass, CO2 and recycling. For all three alternative carbon streams, separate detailed strategies are being developed to achieve the defossilisation of the industry. This is all the more remarkable as North Rhine-Westphalia is the federal state with the strongest industry in Germany, in particular the chemical industry. And it is here, of all places, that a first master plan for the conversion of industry from fossil carbon to biomass, CO2 and recycling is implemented. If successful, NRW could become a global leader in sustainable carbon
management and the region could become a blueprint for many industrial regions.

Most of the composite structures for aircraft are made of carbon-epoxy composites, which can withstand a maximum service temperature of 130°C. As a consequence, carbon-epoxy materials cannot be used in hot zones like engine vicinity areas. The Aeronautical Development Agency (ADA) and CSIR-NAL took up the challenge of developing high temperature resistant composites for use in hot zones of light combat aircraft, which would result in significant weight and cost savings, as well as a considerable reduction in the meantime between failures (MTBF) due to thermal ageing.

The first task was to choose a material system with a service temperature of about ~ 200°C. During the material selection process, it was found that BMI resins are a relatively young class of thermosetting polymers. Hence, a carbon-BMI prepreg was selected due to a number of unique features including excellent physical property retention at elevated temperatures and in wet environments.

It was realized that weight savings and performance can be maximized using co-curing technology. This results in a large reduction of fabrication cycle times, costs and weight. Co-cured structures have fewer fasteners, which results in shorter assembly cycle times and also reduces sealing issues.

A prototype engine bay door assembly was built and tested at 180°C for flight certification. The engine bay door consists of an inner skin and co-cured outer skin assembly with eight transverse stiffeners. The stiffeners were designed with ‘J’ sections. The door size was 1.5 m length, 1 m width and 0.4 m overall depth. The co-cured door was developed using autoclave moulding. Two doors were installed in prototype aircraft and successfully flown.
