A new research project links some of Denmark's leading researchers in PFAS remediation with artificial intelligence. The goal is to develop and optimise a new form of wastewater and drinking water treatment technology using artificial intelligence for zero-pollution goals.

In a new research and development project, researchers from Aarhus University aim to develop a new technology that can collect and break down perpetual chemicals (PFAS) in one step in a purification process that can be connected directly to drinking water wells and treatment plants.

The project has received funding from the Villum Foundation of DKK 3 million, and it will combine newly developed treatment technology from some of Denmark's leading PFAS remediation researchers with artificial intelligence that can ensure optimal remediation.

"In the project, we will design, construct and test a new, automated degradation technology for continuous PFAS degradation. We’re also going to set up an open database to identify significant and limiting factors for degradation reactions with PFAS molecules in the reactor," says Associate Professor Xuping Zhang from the Department of Mechanical and Production Engineering at Aarhus University, who is co-heading the project in collaboration with Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering.

Ever since the 1940s, PFAS (per- and polyfluoroalkyl substances) have been used in a myriad of products, ranging from raincoats and building materials to furniture, fire extinguishers, solar panels, saucepans, packaging and paints.

However, PFAS have proven to have a number of harmful effects on humans and the environment, and unfortunately the substances are very difficult to break down in nature. As a result, the substances continuously accumulate in humans, animals, and elsewhere in nature.

In Denmark, PFAS have been found in drinking water wells, in surface foam on the sea, in the soil at sites for fire-fighting drills, and in many places elsewhere, for example in organic eggs. It is not possible to remove PFAS from everything, but work is underway to remove PFAS from the groundwater in drinking water wells that have been contaminated with the substances.

Currently, the most common method to filter drinking water for PFAS is via an active carbon filter, an ion-exchange filter, or by using a specially designed membrane. All of these possibilities filter PFAS from the water, but they do not destroy the PFAS. The filters are therefore all temporary, as they have to be sent for incineration to destroy the accumulated PFAS, or they end in landfills.

The project is called 'Machine Learning to Enhance PFAS Degradation in Flow Reactor', and it aims to design and develop an optimal and permanent solution for drinking water wells and treatment plants in Denmark that constantly captures and breaks down PFAS, while also monitoring itself.

"We need to be creative and think outside the box. I see many advantages in linking artificial intelligence with several different water treatment technologies, but integrating intelligence-based optimisation is no easy task. It requires strong synergy between machine learning and chemical engineering, but the perspectives are huge," says Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering at Aarhus University.

HeiQ’s biobased textile technologies are set to show how they can change the sleep environment for the better while meeting an increasing demand for sustainable solutions that are in tune with nature. HeiQ Skin Care, HeiQ Allergen* Tech, HeiQ Cool, and HeiQ Mint are going to be showcased at the Heimtextil show in Frankfurt beginning of January.

HeiQ presents a complete set of tailored textile technologies that is said to improve the sleeping environment: "Unlocking Better Sleep". Therefore, HeiQ introduces a range of innovative products designed to enhance the quality of a comfortable night’s rest through sustainable and biobased solutions.

According to a recent study by the School of Architecture, Victoria University of Wellington (New Zealand), “individuals spend more than 50% of their time at home in the bedroom”. Another research from the Fatigue Countermeasures Laboratory, NASA Ames Research Center (United States), concluded that “sleep is critical to health and daytime functioning. For individuals to achieve optimal sleep, they must have access to a sleep environment that allows them to achieve quality sleep.” These are strong indicators that we should treat sleep with the highest importance that it deserves.

The flagship products leading this positive change are the 100% biobased cosmetic technology HeiQ Skin Care, the plant-based deodorizer HeiQ Mint (botanical freshness), the dual action cooling solution HeiQ Cool, and HeiQ Allergen Tech that reduces exposure to inanimate allergens through active probiotics. These biobased innovations are set to redefine the sleep experience and contribute to overall well-being.

HeiQ Skin Care is the most recent addition to HeiQ’s portfolio - a synbiotic textile finish promoting a balanced microbiome for glowing skin. Unlike conventional products, HeiQ Skin Care utilizes pre- and probiotics integrated into a biobased matrix, offering long-lasting cosmetic benefits. It is particularly suited for products that are in direct and long contact with skin, such as pillowcases, duvet covers or bed sheets, acting as a cosmetic care session during sleep.

Within its TEXTILE SOLUTIONS, the CHT Group has developed solution approaches for manufacturing companies in the textile value chain that have to use a lot of energy for their production. This is intended to compensate high energy costs and make a positive contribution to climate protection.Application specialists work with customers to develop individual savings potentials that are specifically tailored to the production facilities and requirements. Thus, depending on the process, fabric and machine, energy savings of up to 30% can be achieved with the use of innovative CHT textile auxiliaries, dyes/pigments and the corresponding process optimisations. In addition, the numerous concepts and optimally matched products can minimise water consumption or shorten the process time.

Energy-efficient cold bleaching instead of pad-steam bleaching processes in continuous pretreatment and the 4SUCCESS process for energy-efficient and resource-saving pretreatment and dyeing of cotton help to save energy. Likewise, the use of polymer binders, which do not require energy-intensive fixation, saves energy.

Efficient pretreatment with the new polymer technology CPT (Comb Polymer Technology) achieves good cleaning effects even with low liquor ratios and thus less water to heat up. To save costs for energy-consuming heating, there is also the gentle low-temperature fixation in the easy care finishing. The OrganIQ EMS Jeans system enables jeans finishing with a reduced application temperature compared to standard processes.

With TIME BOOST, a process for fast polyester dyeing processes, not only significant energy but also time savings are achieved by omitting pre-washing and by shortening heating and migration times. SHORT CUT also leads to shorter process times when dyeing polyamide.

To avoid cost-intensive intermediate drying, the CHT Group offers the SCREEN-2-SCREEN with PRINTPERFEKT S2S which facilitates printing in a wet-on-wet technology.

In addition to numerous other products, the CHT Group also offers its customers digital tools to optimally support process optimizations. The "BEZAKTIV Soaping Advisor" calculation program within the CHT Textile Dyes app can be used to evaluate and improve dyeing and soaping processes in a simple and target-oriented way.

• 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.

The focus is on personnel development, energy and water consumption as well as company-wide emissions and waste behavior. CHT highlights in this report the group-wide projects for climate protection as well as the sustainable products and solutions. The report has been prepared in accordance with the GRI standards of the Global Reporting Initiative (GRI) based on the core option.

With the "Green Deal", the EU Commission is pursuing ambitious climate targets, in the implementation of which the CHT Group is actively involved as part of the VCI initiative "chemistry4climate".
The Group's goal is to become climate-neutral by 2045. To underpin this ambitious target, at the end of 2021 the CHT Group signed up to the Science Based Targets Initiative (SBTi) to meet the goals of the Paris Climate Agreement and committed to the 1.5°C target.
For 2021, the first carbon footprint (Scope 1+2) was prepared for the CHT Group, which now serves as the basis for greenhouse gas emissions reduction targets.

65% of the CHT Group's sales in 2021 were generated with sustainable products. For this, over 88% of the strategic raw material volume was sourced from suppliers classified as sustainable.

Moreover, interesting are the concepts and optimally matched auxiliaries with which energy and resource savings can be implemented for various textile application fields. They vividly and exemplarily demonstrate the efforts to achieve the company's own sustainable and strategic goals, which are derived from the United Nations Development Goals (SDGs).
