From the Sector

Sammlung, Aufbereitung und Wiedereinsatz von Sekundärrohstoffen funktionieren bei klassischen Rohstoffen wie Glas oder Stahl bereits sehr gut. Für einige Wertstoffströme müssen Recyclingtechnologien noch weiterer entwickelt werden, um eine ressourceneffiziente Kreislaufwirtschaft zu etablieren. Dazu gehören beispielsweise Kunststoffe oder Batterien. Die neue Informationssammlung des VDI Zentrums Ressourceneffizienz (VDI ZRE) „Innovative Recyclingtechnologien“ informiert u.a. über Abläufe, neue Entwicklungen in der Entsorgungs- bzw. Recyclingbranche und Förderprogramme für ausgewählte Rohstoffe.
 
Höhere Recyclingquoten sind notwendig, um mehr Wertstoffe im Kreislauf zu führen. Jedoch stellen heterogene Stoffströme, zersplitterte Lieferketten, aufwändige gesetzliche Vorgaben und weitere Faktoren eine effiziente Kreislaufführung vor Herausforderungen. Lösungen gibt es bereits. Einige innovative Recyclingtechnologien werden schon erfolgreich in der Praxis umgesetzt. Weitere sind im Forschungsstadium oder als Pilotprojekte in der Erprobung. Hier setzt die Online-Sammlung „Innovative Recyclingtechnologien“ des VDI ZRE an.

Mit innovativen Technologien Ressourcen sparen
In der Online-Sammlung werden für die Kategorien Kunststoffe, Batterien und Akkumulatoren, Elektrogeräte sowie PV-Module zunächst das Recyclingpotenzial und die Besonderheiten für eine Kreislaufführung aufgeführt. Ein Blick auf den Stand der Technik zeigt aktuelle Möglichkeiten und die Herausforderungen beim Recycling.

Die Vorstellung innovativer Recyclingtechnologien beleuchtet, wie Kreislaufwirtschaft für diese Stoffe ermöglicht, bzw. ressourceneffizient gestaltet werden kann. Viele konstruktive Ansätze sind jedoch noch im Forschungs- und Pilotstadium. Der Handlungsbedarf ist weiterhin hoch. Hier unterstützen weiterführende Informationsangebote z.B. bei der Suche z.B. Fördermöglichkeiten und Netzwerken.

Erstellt wurde die Online-Sammlung „Innovative Recyclingtechnologien“ im Auftrag des Bundesumweltministeriums. Sie wird regelmäßig erweitert. Abrufbar ist sie unter: www.ressource-deutschland.de/themen/kreislaufwirtschaft/innovative-recyclingtechnologien/

AVK, the Federation of Reinforced Plastics, has once again awarded its Innovation Awards to a range of companies, institutes and their partners in 2022. Three innovative composites from each of the three categories Products & Applications, Processes & Methods and Research & Science were honoured during the JEC Forum for Germany, Austria and Switzerland in Augsburg at an award ceremony on 29 November 2022.

At the recent CAMX 2022 Composites and Advanced Materials Expo in Anaheim, California, The Heat Sealing Module – HSM from Zünd was recognized with an Unsurpassed Innovation Award. The HSM significantly facilitates the processing and handling of dry fiber materials with thermoplastic content. This new tool is Zünd’s answer to a demand in the composites industry for wider-spread use and easier processing of these types of materials.

The American Composites Manufacturing Association, ACMA, proclaimed the Heat Sealing Module – HSM the winner of the ACE Award for Unsurpassed Innovation in the “Manufacturing: Equipment and Tooling” category. This award is presented annually to equipment, tooling, a production aid, or software designed to improve manufacturing production, environmental sustainability, or product quality and performance in composites manufacturing.

During processing, dry fiber materials are prone to fraying along the edges. Using hot air, the HSM seals the fabric along the cut path in advance of the Zünd Power Rotary Tool – PRT cutting it. Because of this sealing process, the cut can then be performed at full speed, in any direction, and produces both higher-quality parts and greater production efficiencies.

The HSM helps create clean, sealed edges when cutting fiber-reinforced thermoplastic composites. It benefits not only the cutting process itself, but other production processes downstream. Cutting this way leaves behind no loose or uncut fibers and maintains a clean cutting surface and uncontaminated production environment. At the same time, it ensures that cut parts maintain their shape, and this increased stability makes them much easier to handle, especially in fully automated production workflows.

• Carbios’ biorecycling and biodegradation technologies internationally recognized by consumers as promising answers to their top environmental concerns
• Carbios’ innovations considered one of the best for solving recycling effectively and achieving a real plastic circularity
• Consumer research including qualitative and quantitative fields was conducted between March and August 2022. The research institute, Strategic Research, conducted 6000 interviews in Europe and USA

Carbios’ biorecycling and biodegradation technologies acclaimed by consumers
During the first research field study, respondents were exposed to Carbios’ biorecycling process; a new enzyme-based biotechnology that enables biological recycling of all types of PET plastic waste (including bottles, packaging and textiles), and pushes the boundaries of recycling in terms of the number of cycles.

The research results demonstrated that European and US respondents find Carbios’ biorecycling technology more unique and innovative than traditional PET recycling (i.e. thermo-mechanical recycling), as well as more relevant in its ability to address their concerns and challenges regarding recycling.

In the second research study, conducted in the US, respondents were also exposed to Carbios’ biodegradation technology: an innovative enzymatic solution by which an enzyme is incorporated into plastics during the production process of bio-sourced PLA plastics (corn, sugar cane). This approach makes the material made from plants 100% compostable at ambient temperatures and degradable like plants with the built-in enzyme biologically breaking the bioplastic down in less than eight weeks without microplastics or toxic residues; creating a fully organic circularity.

Similarly to Carbios’ biorecycling technology, Carbios’ PLA biodegradation innovation caught US respondents’ attention with 64% overall liking it. Additionally, 93% of the respondents sampled described the concept as innovative, unique, easy to understand (49%), and believable (43%). Up to 82% of the most environmentally engaged respondents declared they would definitely buy more products made with Carbios’ fully circular biodegradable bioplastic.

Consumers: No other choice but to make plastic fully circular
The research says 99% of the respondents consider it important to protect the environment, while plastic pollution is now ranked the third most-concerning environmental issues after climate change and ocean pollution.

This awareness brings most of these consumers to be environmentally active when it comes to purchasing goods and sorting. For the US respondents, eco-friendly packaging comes in the fourth place in terms of purchase drivers for packaged goods and 65% of them declare sorting plastic from general waste on a regular basis, which makes plastic the most sorted type of waste.

Nevertheless, for a vast majority of the respondents across geographies, even if they would like to reduce their plastic consumption most of the time there is no suitable alternative that is as convenient, light, and cost-efficient as plastics. Hence in an ideal world, consumers would like all plastic waste in landfills and oceans to be collected, cleaned, reused and recycled.

JEC Forum DACH‘s primary goal is to promote the DACH region’s dynamic composites ecosystem. Besides an extensive program of business meetings and conferences, innovation will have a special place in Augsburg from November 29 to 30, 2022 as attendees will have the opportunity to witness the JEC Composites Startup Booster and the AVK Awards. Winners of both competitions will be announced during a dedicated ceremony on November 29th.

The five finalists are:

BioWerkz: Closing the Loops
At BioWerkz a new bio-based, resource-efficient, and CO₂-negative material called “NEWood” is developed,  using only wood waste and agricultural waste bound using fungal mycelium; the root network of mushrooms as a natural binder without the need for any synthetic binders.

Bufo Technology – HARDCORK: High-Performance Biobased Composite – Superior by nature
Bufo Technology has developed the high-performance composite material HARDCORK® made from cork, fibers and a thermosetting matrix. HARDCORK® can be manufactured as a core material, sandwich panel or complex molded part.

Cavicore: Water soluble salt cores for the production of hollow carbon fiber parts
CAVICORE produces ready-to-use water soluble cores for the realization of hollow composite parts. Their “lost cores” have the advantage of being temperature-resistant, stable as well as eco-friendly and recyclable, as they consist of pure salts without binders.

Composite Recycling: Closing the loop on Composite Materials
Composite Recycling has developed a highly energy efficient and sustainable process to separate the resin from the fibres. With the Ecole Polytechnique Fédérale de Lausanne, the team has designed a post-treatment to clean the fibres and make them reusable in new composites, closing the loop.

• Aims to tackle the immense textile waste generated in urban environments, on the back of import bans of waste materials
• Addresses the shortcomings of current textile recycling technologies, which are unsuitable for urban settings due to the use of heavy chemicals
• Technologies developed by the newly-formed RGE-NTU Sustainable Textile Research Centre will be test-bedded in RGE’s pilot urban-fit textile recycling plant, projected for completion as early as 2024

Royal Golden Eagle (“RGE”), a global group of resource-based manufacturing companies, which includes a world-leading viscose fibre producers Sateri and Asia Pacific Rayon (APR), is developing urban-fit, closed-loop textile-to-textile recycling solutions, through the newly-formed RGE-NTU Sustainable Textile Research Centre (RGE-NTU SusTex). This is a five-year research collaboration between RGE and Nanyang Technological University, Singapore (“NTU”), to accelerate innovation in textile recycling that can be deployed in urban settings. The research centre will develop new technologies to recycle textile waste into fibre and create new, next-generation eco-friendly and sustainable textiles.

This move comes on the back of the tightening of waste import bans in countries such as China, India and Indonesia, which are among the world’s largest waste processors. The stricter import bans have left cities in need of viable local textile recycling solutions to tackle the immense textile waste generated.

RGE Executive Director, Mr Perry Lim, said, “Current textile recycling technologies, which rely primarily on a bleaching and separation process using heavy chemicals, cannot be implemented due to environmental laws. At the same time, there is an urgent need to keep textiles out of the brimming landfills.” He added, “As the world’s largest viscose producer, we aim to catalyse closed-loop, textile-to-textile recycling by developing optimal urban-fit solutions that can bring the world closer to a circular textile economy.”

Globally, an estimated 90 million tonnes of textile waste is generated and disposed of every year, with less than 1% being upcycled into new clothing or other textile materials. By 2030, the amount of global textile waste, which currently accounts for almost 10% of municipal solid waste, is expected to reach more than 134 million tonnes. The textile industry is also responsible for 10% of global greenhouse gas emissions – more than international flights and maritime shipping combined.

At present, most of the available textile recycling technologies are open-loop, where textile waste is typically downcycled to lower-quality products (insulating materials, cleaning cloths, etc.) or be used in waste-to-heat recycling.

“Closed-loop textile-to-textile recycling processes, particularly chemical recycling, are still under development. Scaling up the technologies to industrial scale remains a challenge. A key bottleneck is that refabricating textile waste into fibre needs purity standards for feedstock. However, most of the clothes that we wear are made of a mixture of different synthetic and natural fibres, which makes separating the complex blends of materials challenging for effective recycling.

“Our aim is to address this industry pain point by developing viable solutions that use less energy, fewer chemicals and produces harmless and less effluents, and then potentially scale up across our global operations,” Mr Lim said.

To tackle the key challenges in closed-loop textile recycling, RGE-NTU SusTex is looking into four key research areas, namely cleaner and more energy efficient methods of recycling into new raw materials, automated sorting of textile waste, eco-friendly dye removal, and development of a new class of sustainable textiles that is durable for wear and, at the same time, lends itself to easier recycling.

Technologies developed by RGE-NTU SusTex will be test bedded at RGE’s pilot urban-fit textile recycling plant in Singapore, which is projected for completion as early as 2024. If successful, RGE has plans to replicate the plant in other urban cities within its footprint.

Sappi’s popular Algro Design paperboard portfolio also allows the design scope and leeway to communicate brand values in an emotionally appealing way.

Stahl, a proponent of responsible chemistry, is submitting a greenhouse gas (GHG) emissions reduction target that is aligned with the most recent guidance provided by the Science Based Targets initiative (SBTi). The new target marks a key milestone on the company’s journey toward carbon neutrality.

Stahl’s SBTi submission includes a specific commitment regarding the company’s Scope 3 upstream emissions, which Stahl aims to reduce by at least 25% over the next 10 years, compared with the base year (2021). This reduction would primarily be achieved by Stahl replacing its fossil-based raw materials with lower-carbon alternatives. The target is a major step towards the objective of limiting global warming temperature increase to 1.5°C above pre-industrial levels by 2050, as agreed at the 2015 Paris Climate Accords.
 
Stahl’s extended commitment builds on the company’s existing targets to reduce its emission for Scopes 1 and 2, which were set shortly after the Paris Agreement in 2015. Stahl has since reduced its Scope 1 and 2 (direct) GHG emissions by more than 30%, thanks to operational efficiency gains and by decarbonizing its energy supply.

Scope 3 GHG emissions cover all the additional indirect emissions that can occur in the value chain, including those associated with purchased raw materials, packaging, business travel, and transportation. Stahl’s Scope 3 emissions currently represent over 90% of its carbon footprint.

• The Borvida™ portfolio introduces sustainable base chemicals to Borealis’ range of product offering
• The range will initially be based on non-food waste biomass, and chemically-recycled waste; in the future it will also draw from atmospheric carbon capture
• The traceability of the content will be based on Mass Balance, which is ISCC PLUS certified
• This is the next step in an ambitious sustainability journey, which will see Borealis move away from traditional fossil-based feed

Borealis is strengthening its EverMinds™ circular product offering with Borvida™, a range of sustainable base chemicals.

The Borvida portfolio will offer base chemicals or cracker products (such as ethylene, propylene, butene and phenol) with ISCC Plus-certified sustainable content from Borealis sites in Finland, Sweden and Belgium. The move is part of Borealis’ broader commitment to a Future-Positive Revolution, in which the unrivalled benefits of base chemicals and polymers can be enjoyed at minimal impact to the planet.   

The portfolio will initially comprise Borvida B, from non-food waste biomass, and Borvida C, from chemically-recycled waste. In the future, the range will evolve to include Borvida A, sourced from atmospheric carbon capture. Borvida is complementary and is the building block to Bornewables™, a portfolio of polyolefins based on renewably-sourced second generation feedstocks, and Borcycle™, which offers circular polyolefins produced from mechanically- and chemically-recycled plastic waste.

Borealis produces a wide range of base chemicals for use in numerous industries based on various feedstock, such as naphtha, butane, propane and ethane. Through its olefin units (steam cracker and propane dehydrogenation), it converts these into the building blocks of the chemical industry: ethylene, propylene and C4 hydrocarbons (butylenes, ethyl tertiary-butyl ether (ETBE) and butadiene), and C5-6 hydrocarbons (pygas, phenol) among others.

The basis of the Borvida portfolio is Mass Balance, a Chain of Custody model that enables sustainable content to be tracked, traced, and verified through the entire value chain, offering sustainability-assured products from feedstock to end product. Using this model, circular alternatives can be offered in a cost-effective and environmentally-conscious way, which can be scaled up quickly without compromising on quality or efficiency.

Borvida can be used for a wide range of different polymer and chemical applications, also beyond polyolefins (PO). Non-PO polymers, such as polycarbonates, acrylonitrile butadiene styrene (ABS), super absorbant polymer (SAP) and other chemicals, are utilised for various end applications including coatings, plasticizers, adhesives, automotive, electronics, lubricants, detergents, appliances and sports equipment.

Together with key strategic partners, including Neste and Covestro, Borealis strives to provide a long-term solution in order to allow value-chain partners to meet their sustainability goals. Borvida will enable our customers to increase the sustainability of their products, keeping them ahead of forthcoming legislative changes, and meeting their customers’ demands for climate-conscious products.

Introduced on a smaller scale in early 2020, early renewable base chemicals customers include Covestro. “The use of alternative sustainable raw materials is one important pillar of our strategic ambition to become fully circular”, comments Frank Dörner, Managing Director Covestro Procurement Services GmbH & Co. KG. “The new product line is a good example for joint solutions, another strategic pillar, in order to establish new and reliable supply chains creating benefits for our customers.”
