From the Sector

Neste, Alterra and Technip Energies have signed a collaboration agreement to advance the circularity of plastics by providing the industry a standardized technology solution for chemical recycling, also referred to as “advanced recycling”.

The partners aim to globally offer a standardized modular solution, based on Alterra’s proprietary liquefaction technology, to parties interested in building capacity for chemical recycling.

This solution will come in the form of readily designed and engineered liquefaction plant modules, which will allow for lower pre-investment costs, accelerated implementation time, high predictability on project economics and reduced overall capital costs. Contributing to more effective execution of chemical recycling capacity projects, the solution helps the industry to reduce dependency on virgin fossil resources and accelerate the circularity of polymers and chemicals.

Alterra’s technology is a thermochemical liquefaction process, which converts hard-to-recycle plastics into a liquid hydrocarbon product. This liquid intermediate product can then be further refined into high-quality raw materials for new plastics and chemicals. As of today, Neste alone has processed more than 6,000 tons of plastic-derived feeds, including ISCC PLUS certified oil from Alterra’s industrial-scale site in Akron, Ohio.

Combining the expertise of three companies in one solution
Alterra and Neste started collaborating in chemical recycling in 2021, jointly improving aspects of Alterra’s technology and creating respective value chains. Alterra and Technip Energies started their collaboration in chemical recycling in 2022. The three companies now join efforts in a unique endeavor: Alterra and Neste will license the liquefaction technology and Technip Energies will design, engineer and deliver the standardized liquefaction plant solution to interested parties globally.

CARBIOS and FCC Environment UK, a recycling and waste management companies in the UK, have signed a Letter of Intent (LOI) to jointly study the implementation of a UK-based plant using CARBIOS’ PET biorecycling licensed technology.  CARBIOS’ biorecycling technology is key to supporting FCC’s continuing goal of contributing to the circular economy by exploring new processes and technologies to produce recycled PET (r-PET) from PET plastic and textiles. For CARBIOS, this LOI confirms interest from the waste management sector, in addition to plastic producers, and would mean a foothold for its technology in the UK.

FCC’s continuing contribution to the UK circular economy
Recycling has plateaued in the UK in recent years, but UK Government policy very much supports a continual move to a more circular economy which FCC Environment supports. Achieving a circular economy however requires innovation and investment to deliver real environmental change. Exploring biorecycling is one way of doing this, so FCC is keen to understand this technology better by seeking an evidence based view on the advantages of using enzymes for the treatment of PET such as lower energy consumption and better circularity of the polymers back into the PET production lines. The depolymerization process developed by CARBIOS also facilitates the recycling of all kinds of PET waste, including problematic fractions such as polyester textiles, into high-quality recycled PET.

UK PET biorecycling plant would process hard-to-recycle waste
In order to tackle the plastic waste crisis, CARBIOS has developed a enzymatic depolymerization technology that enables efficient and solvent-free recycling of PET plastic and textile waste into virgin-like products. CARBIOS has ambitious plans to become a leading technology provider in the recycling of PET by 2035. In addition to the world’s first industrial-scale enzymatic PET recycling plant which is currently under construction in Longlaville, France, this UK-based plant would process PET waste that is currently not recyclable using conventional recycling technologies, such as colored, multilayered or textile waste.

The current European Football Championships 2024 in Germany will be played on natural turf, which is very costly to maintain, does not tolerate high frequency of use and has a limited service life of only 6 months in some cases. Artificial turf is easier to maintain and correspondingly popular. In Germany, there are estimated to be more than 5,000 artificial turf pitches and as many as 25,500 across the EU. The drawback: the enormous annual emission of microplastics in the form of infill material, the high CO2 impact and the not environmentally friendly disposal. Researchers in Aachen presented a sustainable alternative: BioTurf is a new artificial turf system made from bio-based polymers that no longer requires polymer infill material!

"Every year, around 500 kilograms of plastic granules are produced per artificial turf pitch, which have to be refilled as infill. This also corresponds to the amount that potentially enters the environment as microplastics per sports pitch," explains Dr Claudia Post from TFI. With an estimated 25,000 artificial turf pitches in the EU, artificial turf in Europe alone produces 12,750 tonnes of microplastics that end up in the environment every year! The TFI - Institut für Bodensysteme an der RWTH Aachen e.V., Institute for Research, Testing and Certification in Europe for Indoor Building Products, has developed the innovative artificial turf system together with the ITA (Institute for Textile Technology at RWTH Aachen University) and in collaboration with the company Morton Extrusionstechnik (MET), a specialist in artificial turf fibres.

"New artificial turf pitches will be phased out by 2031 at the latest due to the ban on plastic granules. Even now, artificial turf pitches with infill material are no longer being subsidised," says Dr Claudia Post. For grassroots sports, clubs, cities and local authorities, converting their existing artificial turf pitches will be a mammoth task in the coming years, as artificial turf pitches have to be replaced every 10-15 years. With BioTurf, an environmentally friendly alternative is now available! The surface can be played on like any other, whether running, passing or kicking. Short, heavily crimped blades support longer blades and this simple approach increases playing comfort. BioTurf fulfils all quality requirements and standards for the highest footballing demands.

"BioTurf is an innovative, holistic solution," emphasises Dirk Hanuschik from TFI. "We use rapeseed oil and agricultural waste that does not compete with food production. BioTurf is also almost completely recyclable".
This is in stark contrast to conventional artificial turf, which can currently only be thermally utilised, i.e. burned to generate heat.

As BioTurf does not require the traditional latex process at all, the energy-intensive drying process can be dispensed with, which has a positive effect on the price. Latex is also difficult to recycle. In contrast, BioTurf uses the new thermobonding technology. Here, the thermoplastic pile yarns are thermally fused to the backing. Further development steps still need to be taken in the endeavour to develop a 100% mono-material artificial turf, as a few percent polypropylene still needs to be processed in the backing in addition to the polyethylene fibre material in order to protect it during thermobonding. However, this does not hinder its recyclability.

Stahl has joined the Global Organization for PHA (GO!PHA), a non-profit platform that advocates and advances the use of polyhydroxyalkanoates (PHAs), a naturally occurring polymer that offers a lower-impact, bio-based alternative to traditional fossil-based plastic feedstocks.  

GO!PHA is a coalition of over 60 stakeholders ranging from producers and formulators to users as well as universities and research institutes. The members, all early adopters of PHAs, work together to increase understanding of this relatively new PHA technology and advance the science behind these renewable, compostable and biodegradable materials. As a member of the network, Stahl will have the opportunity to join forces with the wider PHA value chain to help move PHAs beyond the testing phase and accelerate the potential application of the technology in the coatings market.

For a super-soft handle, the SILIGEN® EH1 is a vegan silicone macro-emulsion softener with 35% plant-based active content.

Lightweight design is a key enabler for addressing the energy transition and sustainable economy. Following the liquidation of the state agency Leichtbau BW GmbH, a consortium consisting of the Allianz Faserbasierter Werkstoffe Baden-Württtemberg (AFBW), the Leichtbauzentrum Baden-Württemberg (LBZ e.V. -BW) and Composites United Baden-Württemberg (CU BW) now represents the interests of the lightweight construction community in the State.

The Lightweight Design Agency for Baden-Württemberg is set up for this purpose on behalf of and with the support of the State. The Lightweight Construction Alliance BW is the central point of contact for all players in the field of lightweight construction in the State and acts in their interests at national and international level. Professor Markus Milwich from the German Institutes of Textile and Fiber Research Denkendorf (DITF) represents the agency.

The use of lightweight materials in combination with new production technologies will significantly reduce energy consumption in transportation, the manufacturing industry and the construction sector. Resources can be saved through the use of new materials. As a cross-functional technology, lightweight construction covers entire value chain from production and use to recycling and reuse.

The aim of the state government is to establish Baden-Württemberg as a leading provider of innovative lightweight construction technologies in order to strengthen the local economy and secure high-quality jobs.

Among others, the "Lightweight Construction Alliance Baden-Württemberg" will continue the nationally renowned "Lightweight Construction Day", which acts as an important source of inspiration for a wide range of lightweight construction topics among business and scientific community.

Professor Milwich, an expert with many years of experience and an excellent network beyond the State's borders, has been recruited for this task. In his role, Milwich also represents the state of Baden-Württemberg on the Strategy Advisory Board of the Lightweight Construction Initiative of the Federal Ministry for Economic Affairs and Climate Action, which supports the cross functional-technology and efficient transfer of knowledge between the various nationwide players in lightweight construction and serves as a central point of contact for entrepreneurs nationwide for all relevant questions.

From 2005 to 2020, Professor Milwich headed the Composite Technology research at the DITF, which was integrated into the Competence Center Polymers and Fiber Composites in 2020. He is also an honorary professor at Reutlingen University, where he teaches hybrid materials and composites. "Lightweight design is an essential aspect for sustainability, environmental and resource conservation. I always showcase this in research and teaching and now also as a representative of the lightweight construction community in Baden-Württemberg," emphasizes Professor Milwich.

The German Institutes of Textile and Fiber Research Denkendorf (DITF) have modernized and expanded their melt spinning pilot plant with support from the State of Baden-Württemberg. The new facility enables research into new spinning processes, fiber functionalization and sustainable fibers made from biodegradable and bio-based polymers.

In the field of melt spinning, the DITF are working on several pioneering research areas, for example the development of various fibers for medical implants or fibers made from polylactide, a sustainable bio-based polyester. Other focal points include the development of flame-retardant polyamides and their processing into fibers for carpet and automotive applications as well as the development of carbon fibers from melt-spun precursors. The development of a bio-based alternative to petroleum-based polyethylene terephthalate (PET) fibers into polyethylene furanoate (PEF) fibers is also new. Bicomponent spinning technology, in which the fibers can be produced from two different components, plays a particularly important role, too.

Since polyamide (PA) and many other polymers were developed more than 85 years ago, various melt-spun fibers have revolutionized the textile world. In the field of technical textiles, they can have on a variety of functions: depending on their exact composition, they can for example be electrically conductive or luminescent. They can also show antimicrobial properties and be flame-retardant. They are suitable for lightweight construction, for medical applications or for insulating buildings.

In order to protect the environment and resources, the use of bio-based fibers will be increased in the future with a special focus on easy-to-recycle fibers. To this end, the DITF are conducting research into sustainable polyamides, polyesters and polyolefins as well as many other polymers. Many 'classic', that is, petroleum-based polymers cannot or only insufficiently be broken down into their components or recycled directly after use. An important goal of new research work is therefore to further establish systematic recycling methods to produce fibers of the highest possible quality.

For these forward-looking tasks, a bicomponent spinning plant from Oerlikon Neumag was set up and commissioned on an industrial scale at the DITF in January. The BCF process (bulk continuous filaments) allows special bundling, bulking and processing of the (multifilament) fibers. This process enables the large-scale synthesis of carpet yarns as well as staple fiber production, a unique feature in a public research institute. The system is supplemented by a so-called spinline rheometer. This allows a range of measurement-specific chemical and physical data to be recorded online and inline, which will contribute to a better understanding of fiber formation. In addition, a new compounder will be used for the development of functionalized polymers and for the energy-saving thermomechanical recycling of textile waste.
