From the Sector

Archroma launched Perapret® AIR liq, a new light-activated air purification technology for all kinds of fabrics. The new innovation was presented at the Techtextil last month.

The mineral-based Perapret® AIR liq eliminates air pollutants and airborne smells by imitating the natural process of photocatalysis under normal day and artificial light sources.

The chemistry usually used in such applications is nano-sized TiO2 (dioxide titanium), which attack every organic matter, including the textile fiber, and not only pollutants.

Perapret® AIR liq is produced using a patented Core Shell technology that partially surrounds the TiO2 molecules, solving the issue of fiber damage, and at the same time still allowing the photocatalytic process to work efficiently.

Therefore, the innovative Core Shell technology behind Perapret® AIR liq makes it possible to use the capabilities of nano-sized TiO2 also on organic based substances such as cotton, polyester, polyamide, viscose and any additional fiber and its blends.

In addition, the treatment is highly durable, as the product doesn’t self-consume and retains its performance over time.

Perapret® AIR liq is ideally suited for indoor applications, such as curtains, textile wall coverings, as well as cars and other automotive interiors, allowing to reduce air pollutants and airborne smells and thus improving overall air quality*.

The technology is at the core of CLEAN AIR, a new system that combines Perapret® AIR liq with other recent innovations such as Smartrepel® Hydro TS liq for PFC-free** durable water repellence, and Sanitized® T27-22 liq antimicrobial agent.

On June 13, EREMA Group and Borealis invited representatives of the international plastics and recycling trade press to Upper Austria for a sneak preview of the technological developments and lighthouse projects that the companies will present at K 2022, the plastics industry's international meeting place. The venue for the pre-K event was EREMA Group headquarters in Ansfelden.

EREMA Group K 2022 preview
In Düsseldorf, the subsidiaries of the EREMA Group - which are EREMA, PURE LOOP, UMAC, 3S, KEYCYCLE and PLASMAC - will present their technological innovations, services and support together at a Group trade fair stand for the first time. Seven new recycling systems and components will be presented that enable large-scale plants with a production capacity of up to 6 t/h while setting a milestone in recyclate quality and process stability. This is made possible by technological innovations in the plasticizing unit that have been specially developed for high throughputs with low specific energy consumption, the new EREMA 406 laser filter with a 50 percent larger screening area, and new digital assistance systems that will be launched at K 2022 and made available on the BluPort® customer platform. These include, for example, the PredictOn app, which helps to anticipate and eliminate imminent malfunctions based on continuous measurement and evaluation of machine data.

New series of machines for new target groups
For customers looking for rapidly available recycling systems for simple applications, EREMA Group subsidiary UMAC has an innovation in store for K 2022. The company, which has so far specialised in refurbishing and trading in previously owned equipment, is expanding its business area and in Düsseldorf will launch READYMAC, a standardised, prefabricated recycling solution that can be produced from stock, based on proven EREMA TVE technology.

Finally, in the inhouse recycling segment, PURE LOOP and PLASMAC will round off the wide range of machines offered by the group of companies with their product portfolio.

Live recycling and lighthouse projects at the Circonomic Center
In the outdoor area of the K show, EREMA will bring plastics recycling to life with live demonstrations in conjunction with cooperation partners. Different waste streams are processed for this purpose. The wide variety of high-quality applications for recyclate will be showcased in the "products made of recyclate" exhibition, ranging from technical components to consumer goods and food packaging.

Borealis – accelerating the transition towards a more circular future
Borealis is committed to using their expertise and global reach to advance the circular economy of plastics. At the joint Pre-K 2022 kick-off on June 13, Borealis provided a preview of their integrated way of circular thinking and featured topics and activities at the K Fair 2022 in October. The preview covered new technologies and innovations including new packaging and infrastructure applications of the Bornewables™ portfolio of circular polyolefin products, manufactured with renewable feedstocks.

Indorama Ventures Public Company Limited (IVL), a global sustainable chemical company, has signed a license agreement with Shandong Binhua New Material Co., Ltd. (Binhua), a subsidiary of Befar Group, a leading petroleum and chemical enterprise in China, to build, own and operate a propylene oxide (PO), t-Butanol (TBA) and t-Butyl methyl ether (MTBE) co-production unit.

Featuring the world’s only MTBE ‘single-step’ reaction technology, IVL’s proprietary innovation, the project is part of the ‘C3 and C4’ comprehensive utilization project in Shandong, China. It is one of the largest in the province, covering an area of over one million square meters.

Under the contract, IVL will provide a design package, technology, operational know-how and training to enable the construction and operation of a PO co-production with MTBE and TBA units for Binhua. The plant is part of a larger complex comprising propane dehydrogenation to propylene, butane isomerization, synthetic ammonia, and other installations.

With the goal of making recycling of lightweight, high-volume fiber and flake recyclate much more economical and, in some cases even possible, Coperion has developed a new version of its ZS-B side feeder. Using the innovative ZS-B MEGAfeed, plastic recyclate with a bulk density under 200 kg/m³, long considered intake-limited and thus not worth recycling, can be reliably fed in large quantities into Coperion’s ZSK twin screw extruder and be concurrently recycled and compounded.

The ZS-B side feeder’s novel design makes it possible to feed very high rates of fiber and flakes, such as PA, PE, PET, and PP. As a result, the ZSK twin screw extruder’s high capacity can be fully exploited when the ZS-B MEGAfeed is used. Very high throughputs in both mechanical and chemical recycling of post-industrial and post-consumer waste are achieved.

Increased Throughput in Numbers
With a ZSK 58 Mc18 twin screw extruder, the throughput increase and thus the potential of the new ZS-B MEGAfeed becomes very clear. When recycling PA fibers with a bulk density of ~40-50 kg/m3, throughputs of 70 kg/h were previously achieved using conventional equipment. When the PA fibers were fed into the ZSK extruder using the ZS-B MEGAfeed, throughputs increased about fourteenfold to 1,000 kg/h. Similar results were achieved recycling carbon fibers with a bulk density of ~50-70 kg/m3; in this case, throughputs increased from 50 kg/h to 2,500 kg/h using the ZS-B MEGAfeed. When recycling PCR (Post-Consumer Recycled) flakes, throughputs increased from 50 kg/h to 700 kg/h, and from 80 kg/h to 1,300 kg/h with multilayer film flakes.

Key to Economical Recycling of A Wide Variety of Plastics
Plastics previously considered not recyclable are becoming a valuable raw material using the new Coperion ZS-B MEGAfeed. For example, PCR flakes or recyclate from carbon fiber-reinforced plastics can now be fed into the ZSK extruder at high feed rates and recycled economically.

In the case of mechanical upcycling, upstream processes necessary for compounding, such as compacting, melting and agglomeration, are completely eliminated using the ZS-B MEGAfeed technology. In this recycling process, flakes and fibers can be fed directly into the ZSK extruder, where they are melted, compounded, devolatilized, and filtered in a single step. In so doing, both investment costs and energy consumption drop. The production process becomes significantly more efficient. Moreover, the thermal product stress is reduced and recyclate quality increases.

Even when recycling PET, the feed rate is no longer a limiting factor. With the ZS-B MEGAfeed, PET flakes and fibers can be fed into the ZSK twin screw extruder in large quantities with no pre-drying or crystallizing, where they can be processed with the highest degree of profitability.

The ZS-B MEGAfeed can also feed large quantities of post-consumer waste, adding appreciable value to the chemical recycling process with the ZSKs. ZSK throughput rates are very high with the ZS-B MEGAfeed. Preheating of the recyclate via mechanical energy input of the twin screws thus becomes even more economical for further processing in the reactor.

Existing Coperion extruders can be retrofitted with ZS-B MEGAfeed technology to greatly expand their spectrum of applications and increase their throughput rates.

The story started with a huge market demand for the industrial synthesis of Indigo during the late nineteen century. The first Industrial Synthesis of Indigo, Indigo Pure BASF, was successfully manufactured and introduced into the market by BASF in July 1897. It was a significant achievement for the German Chemical Industry.

Over the years, the product has made revolutionary changes to the supply chain. New technologies enabled the transformation of Synthetic Indigo Powder application to pre-reduced DyStar® Indigo Vat 40% Solution. Being the pioneer in the market, the pre-reduced solution set an important industry milestone when it was first launched in 1998.

DyStar’s innovation remains a core catalyst in our chemistry research and development journey. When the DyStar® Indigo Vat 40% Solution was introduced, the core intelligence lies behind the benefits from Sustainability to Health and Safety. The technology transforms Indigo into its soluble Leuco form, making the Indigo dyeing process more sustainable, efficient, and stable in production. In addition, workers in Denim Mills can be assured of product safety as well.

Similarly, in recent modules under Cadira® Denim, DyStar introduced the first salt-free Indigo dyeing process in history. The applied technology completely eliminates hydrosulphite in the application of Indigo.

TEXAID as a professional collector and sorter with roots in Switzerland contributes to this ecosystem to enable the textile-to-textile recycling.  The creation of Swiss Textile Recycling Ecosystem marks a key milestone in the upscaling of Worn Again Technologies’ recycling process technology with technology scale-up partner Sulzer Chemtech in Winterthur. It also supports its ambition to create a circular economy where non-reusable, hard-to-recycle textiles can be reintroduced into supply chains to become new fibers.

To cause a paradigm shift in the fashion industry and realize true circularity requires all members of the value chain to be on the same page and working towards the same goals. The Swiss Textile Recycling Ecosystem is a network comprising fabric and textile manufacturers, waste collectors and sorters, as well as retailers, brand owners and technology providers – all coordinated by Swiss Textiles. All these parties will cooperate to make their shared vision of a more sustainable fashion industry a reality, where used textiles can be recycled into new textiles.

TEXAID as a stakeholder in the Swiss Textile Recycling Ecosystem and as leading textile recycling company with over 40 years of experience will support the initiative through collecting, sorting, pre-processing and providing pre- and post-consumer feedstock to the Demonstration Plant. At its headquarters in Schattdorf (CH), TEXAID will investigate possibilities to automate the sorting and pre-processing of textile feedstock for recycling. Currently, TEXAID processes more than 80,000 tons of end-of-use textiles and footwear every year all over Europe and the US.
