From the Sector

In accordance with California’s Proper Labeling of Wet Wipes law (AB 818), state wastewater agencies and industry experts went deep to find out exactly what is passing through—and clogging up—municipal wastewater systems. The Responsible Flushing Alliance (RFA) alongside the California Association of Sanitation Agencies (CASA) and the Association of the Nonwoven Fabrics Industry (INDA) released the results from the largest known domestic sewage collection study conducted to reveal what’s really being flushed down the drain – and shouldn’t be.

“We took a forensic approach to this collection study, engaging industry and wastewater experts to examine our findings and determine what exactly is being flushed and how much of it,” said Adam Link, Executive Director at CASA, a co-sponsor of the Proper Labeling of Wet Wipes Law. “Now that we have the data to see what Californians are flushing and the types of non-flushable items that are causing issues within wastewater systems, local agencies can refine their public outreach and messaging to target specific problems and educate more efficiently.”

Collection and material investigation took place in October 2023 at two locations: Inland Empire Utilities Agency (IEUA) in Southern California and Central Contra Costa Sanitary District (Central San) in the greater San Francisco Bay Area in Northern California. Wastewater and wipes experts collected, sorted and identified more than 1,700 items pulled from the two locations during peak flow times. Kennedy Jenks, an independent engineering firm, designed the study and compiled the findings into the report.

Why Study What’s Being Flushed?
When products that aren’t meant to be flushed down the toilet wind up in the sewer system, it can cause serious threats to public and environmental health. In fact, estimates show that local public agencies throughout California (and the ratepayers they represent) are spending more than $47 million annually to repair wastewater treatment equipment and respond to sewer overflows caused by improper flushing.

“Part of keeping communities healthy requires not flushing things we shouldn’t,” said Lara Wyss, President of the RFA. “However, the data to support which non-flushable items to target as part of education campaigns has been lacking. That’s likely why when we surveyed Californians about what they are flushing, the results revealed that approximately 25% think baby wipes are flushable (which is never true) and 60% self-reported that they flushed something they knew they shouldn’t have.2 Our study results reinforce that finding, as more than 99% of materials collected were items that shouldn’t have been flushed.”

The breakdown of items collected from pipes at the two study locations included:
•    34.1% wipes labeled with the “Do Not Flush” symbol (baby wipes, cleaning wipes, makeup wipes, etc.)
•    64.9% other non-flushable items (paper towels, period products, trash, etc.)
•    0.9% wipes labeled as flushable

“We pulled material larger than 1-inch square directly from the bar screens, and it wasn’t until everything was sorted and identified that we could see what we actually had,” said Matt O’Sickey, Director of Education and Technical Affairs, INDA. “There were a lot of paper towels and baby wipes and all of the ‘Do Not Flush’ labeled wipes we collected were fully intact, showcasing why they should never be flushed.”

What Not to Flush—and How We Tell Consumers
According to the Proper Wet Wipes Labeling law, manufacturers of non-flushable wipes, including products such as baby wipes, cleaning wipes, makeup removal wipes and many others that are primarily used in a bathroom setting must include the “Do Not Flush” symbol on the front of the packaging.
The #FlushSmart consumer education campaign promotes the “Do Not Flush” symbol and provides information on what should and should not be flushed. The message shared with consumers is simple: Look for the “Do Not Flush” symbol on wipes packaging, and if you see it – throw the wipe out. Extrapolating from the results of this study, refraining from flushing “Do Not Flush” labeled wipes, paper products and feminine hygiene products would capture over 90% of items clogging sewers.

After four decades in the packaging industry, the Manjushree Group is entering the Indian nonwovens market. The entrepreneurs rely on a flexible RF Smart Composite line from Reifenhäuser Reicofil to meet very different customer requirements.

The Manjushree Group operated a blown film line for packaging materials for the tea industry in the eastern part of India as early as 1983. In the years that followed, Manjushree Technopack Ltd. developed into one of the largest suppliers of solutions for rigid plastic products in South Asia - and the family business grew into a group with several business segments. In 2018, the entrepreneurial family repositioned itself: it sold its previous core business to a financial investor and established Manjushree Ventures with footholds in start-up financing, real estate business, and manufacturing - the largest of which is Manjushree Spntek as a producer of high-quality spunmelted fabrics.

Since February 2023, Manjushree Spntek has been producing high-performance spunmelts on an RF Smart Composite line from Reifenhäuser Reicofil - benefiting both from many years of experience in the packaging industry and from experience with Reifenhäuser's blown film lines. "We know a lot about plastic extrusion, for example when it comes to line operating parameters such as temperature and pressure. Processing is similar in both industries," explains Rajat Kedia. "The main difference is the distribution of the products: In plastic packaging, we had an established customer base and sold a lot of material to the big consumer goods manufacturers. The nonwovens market in India, on the other hand, is still forming, with thousands of small companies currently getting involved." These serve customers in their regions, such as hospitals.

The RF Smart Composite line is a standardized spunmelt line for smaller and emerging markets. The line produces nonwovens of the highest Reicofil quality with appropriately adapted throughput. This makes it ideally suited for applications in hygiene and medical technology and, with typically 8,200 annual production hours, it is extremely reliable. In addition, operators can start production quickly because in many cases the line can be integrated into existing buildings.

Before production could start, Manjushree built a new production building in Bidadi, a town an hour's drive from Bangalore International Airport. The building is designed to be sustainable: It uses natural light and fresh air, has comprehensive contamination control, and obtains almost all of its energy from renewable sources. Reifenhäuser Reicofil then installed, commissioned and tested the RF Smart Composite line.

Since February 2023, Manjushree Spntek has been producing high-quality spunmelted nonwovens, including ultra-soft fabrics and fabrics with special coatings for customers in the hygiene and medical industries. The material can be used, for example, for baby diapers and feminine hygiene products, but also for medical articles ranging from surgical gowns to surgical drapes.

Kelheim Fibres, a manufacturer of specialty viscose fibres, showcases its latest developments at this year's Global Fiber Congress in Dornbirn. The focus is on innovative solutions that not only promote environmental sustainability but also strengthen the European supply chain.

In his presentation "Towards high performing plant-based AHP products - a joined approach of Pelz and Kelheim Fibres," Dr. Ingo Bernt, Project Leader of Fiber & Application Development at Kelheim Fibres, together with Dr. Henning Röttger, Head of Business Development at PelzGROUP, introduces the development of a plastic-free yet high-performance panty liner. The water-repellent Kelheim specialty fibre Olea plays a crucial role in both the top and backsheet of the panty liner. This product emerged from the ambition to offer eco-friendly alternatives to conventional disposable hygiene solutions without compromising on product performance.

A similar approach is pursued in the second presented project. Under the title "Performance Fibres meet Sustainable Design - example of a reusable Baby Diaper," Natalie Wunder, Project Leader from Kelheim Fibres' New Business Development team, together with Caspar Böhme, Co-Founder of Sumo, introduce the washable and reusable SUMO diaper. Made from biobased materials and featuring a unique construction with Kelheim specialty fibres, this combination offers double environmental benefits compared to conventional disposable baby diapers.

Both the panty liner and the SUMO diaper are manufactured entirely in Europe, resulting in shorter transportation routes and a reduced CO2 footprint. Moreover, these innovations contribute to strengthening the European textile and nonwovens industries by fostering innovation within Europe.

International technology group ANDRITZ has received an order from Predo Health Products Inc, Türkiye, for delivery of two high-speed hygiene converting lines to produce adult open diapers and feminine sanitary napkins. With this investment, Predo is entering the growing adult and femcare market. The company already operates four baby diaper lines from ANDRITZ.

The two state-of-the-art lines are designed for high-speed production and contain the most advanced forming technology for absorbent core and SAP (superabsorbent polymers) dosing. Based on their flexibility and user-friendly configuration, Predo will be able to produce a wide range of different product compositions and sizes. In addition, the lines are designed for zero waste production. This will enable Predo to produce high-performing products with a sustainable approach.

The lines will be installed in Predo’s factory in Gaziantep, with start-up scheduled for the first half of 2024.

Predo is one of the leading manufacturers of baby care products and is expanding its business to other hygiene sectors. The company exports to 55 countries across the globe.

SABIC will present its portfolio of PURECARES™ and TRUCIRCLE™ materials for the healthcare and hygiene market at INDEX™23 from April 18 to 21 in Geneva, Switzerland, under the theme of ‘Collaborating for sustainability and innovative solutions’.

At INDEX, SABIC will highlight a joint project with two market leaders, using certified circular polymers from the TRUCIRCLE portfolio in recyclable films for feminine hygiene, baby care and disposable medical applications. In all of these cases from diapers to surgical drapes and medical gowns, the sustainable materials can serve as direct drop-in alternatives with no compromise in production efficiency and product performance.

Further examples on display at the company’s booth will feature TRUCIRCLE solutions for facemasks, including an N95 design that localizes the value chain with SABIC® PURECARES PP spunbond and meltblown polymers in Saudi Arabia. SABIC provides complete solutions for facemask production as part of its localization strategy and has been a key enabler of the Saudi Made initiative. Also shown will be a closed-loop facemask developed in collaboration with industrial and research partners in Europe.

The company’s PURECARES polyolefin products are based on technologies free of both tris (nonylphenyl) phosphite (TNPP) and phthalates. Consumer comfort is achieved by using SABIC polypropylene (PP) and polyethylene (PE) polymers for bi-component fibers to answer multiple needs for soft and loft handfeel nonwovens, enabling easy lamination to other building blocks on medical nonwovens or absorbent hygiene applications.

In addition, SABIC produces TRUCIRCLE certified circular polymers for its PURECARES PP and PE portfolio with feedstock based on advanced recycling of mixed and used plastic that would otherwise typically not be suitable for mechanical recycling processes. These more sustainable solutions can be adopted in downstream processes as direct drop-in alternatives to incumbent materials with no compromise in production efficiency, purity and product performance.

FIBRELLA® Strata’s unique tri-layer structure makes it stand out on the market,” says Tara Millar, Manager, Category Management, Americas.

• with a ready-to-use swatch book dedicated to its DEEP DIVE sustainable dyeing system for dark, popular color basics

Archroma, a global leader in specialty chemicals towards sustainable solutions, launches its first ever ready-to-use swatch book, dedicated to creating sustainable black and dark color basics for faster time to market, to support its popular DEEP DIVE 2.0 system.

In 2018, Archroma launched its system solutions, a holistic approach aimed at addressing the growing expectations of the public in terms of keeping consumers, and the environment, safe.
Under the umbrella of "The Archroma Way to a Sustainable World: Safe, efficient, enhanced, it's our nature", the Archroma systems are designed to create innovation and performance, whilst reducing the impacts on water, energy and other natural resources. The savings generated by these 70+ system solutions are demonstrated by Archroma's proprietary ONE WAY Impact Calculator, a ground-breaking tool launched in 2012 and continuously upgraded to simulate and optimize the footprint of textile application processes.

One of these systems, DEEP DIVE 2.0, has attracted a lot of interest not just from textile manufacturers but also from major brands and retailers worldwide. This popular system combines Drimaren® Ultimate HD, high-performance reactive dyes, with Blue Magic, an all-in-one pretreatment, Optifix® RUB New liq and Siligen® SIH-S New liq, a finishing treatment improved rub fastness and elegant hand feel, and an effective hydrolyzed dye remover, Cyclanon® XC-W New liq. The result is a shorter dyeing process combining right-first-time productivity, an improved fabric quality for longer lasting end-articles, as well as dramatically reduced water and energy utilization for brands committed to drive more sustainable production. Savings can reach up to 31% water and 34% energy.

The system is ideally suited for medium and dark cottons that have high performing fastness to light, multiple home laundering, saliva – in other words: apparel used for fashion, sports and baby’s wear.
At the same time, interested manufacturers and brands were facing the constant challenge of the fashion industry: time to market.

Often design is separated from execution in the factory and as such often designers initially select color that cannot be met in reality on different fibers or production routes in terms of color flare, metamerism, brightness, depth and now sustainable metrics – leading to lengthy delays and compromises in function, performance and/or color.
Archroma decided to create a dedicated tool aimed at addressing these issues. The company developed a new, unique book with color swatches made with the system that is ready to implement immediately into production thanks to engineered color standards and specifications.

This new tool offers a path to bridge the gap between “art and science” by providing at inspiration phase fully executable deep colors for cotton with controlled color metamerism and at the same time demonstrate water, energy and chemical savings, enhanced color fastness using safe chemistry for the end consumer. As a wardrobe staple, medium to dark shades are very popular with consumers. As a result, most brands and retailers often have and sell up to 60% of medium to dark shades in their seasonal palettes. It’s also the dark shades that use the most water and energy in production, so prioritizing these colors would have the largest ecological positive impact. The 48 colors swatched in the DEEP DIVE 2.0 book have been selected based on market popularity to allow brands and manufacturers to match that very stable market demand. Customers may use these colors as presented, or as inspiration whereby Archroma can create and match new custom colors using the DEEP DIVE 2.0 system.

Christophe Maestripieri, Global Head of the Archroma Brand Studio, the company’s department dedicated to support brands’ projects and innovations, explains: “We wanted to make sure our partners have all the tools they need to convert to more sustainable colors. We had the ideal dyeing system to do that, DEEP DIVE 2.0, with its high performance and reduced impacts on resources. Now, with the new DEEP DIVE 2.0 swatch book, we also offer to brands and manufacturers a way to select sustainable color options that meet the market demand for high quality medium to dark shades which can be implemented into production right away.”

Suominen launches a carbon neutral nonwoven, BIOLACE^® Zero. BIOLACE^® Zero is an excellent product for many kinds of wiping applications like baby, personal care, and household wipes. It has excellent wet and dry strength and it’s very soft. It is made of 100% cellulosic lyocell fibers and the product is 100% biodegradable, compostable and plastic free.

BIOLACE^® Zero utilizes VEOCEL™ Lyocell fibers from Suominen´s long-term partner Lenzing. BIOLACE^® Zero is made of 100% carbon neutral VEOCEL™ Lyocell fibers.

“We are very excited to introduce BIOLACE^® Zero, which is not just Suominen´s first carbon neutral product, but also one of the first carbon neutral nonwovens on the market. BIOLACE^® Zero will be available as part of Suominen's sustainable product portfolio”, says Marika Mäkilä, Senior Manager, Category Management, Europe.

Suominen’s BIOLACE^® Zero and Lenzing’s VEOCEL™ Lyocell fibers are certified as carbon neutral products by globally recognized company, ClimatePartner. Carbon neutrality means that the greenhouse gas emissions of nonwoven have been calculated – from the raw material production to the client’s production facility – reduced and are offset through certified carbon offset projects.

Suominen is a pioneer in sustainable nonwovens and we have a wide range of sustainable nonwoven products for different applications. Suominen’s R&D team has excellent know-how on sustainable fibers and we are also continuously collaborating with innovative partners to develop new and innovative solutions with a reduced environmental impact into our product portfolio.

“With this new carbon neutral product BIOLACE^® Zero we are able to support our customers in their greenhouse gas emissions reduction targets. Innovating new products in collaboration with partners such as Lenzing by using carbon neutral VEOCEL™ Lyocell fibers is well aligned with our strategy and vision to be the frontrunner in sustainable nonwovens”, says Noora Rantanen, Manager, Sustainability & Marketing.

Up to the age of three, a baby uses around 5,000 diapers. Despite the convenient handling of common disposable diapers, parents are increasingly looking for a healthy and sustainable alternative to these products to avoid waste. In Germany alone, 10 million diapers are disposed of every day.

Ways to solve this dilemma, would be disposable products that are made from bio-based or biodegradable materials, or reusable products with a longer life span replace disposable products.

Founding team Luisa Kahlfeldt and Caspar Böhme combine both with their "Sumo Diapers." These cloth diapers are made entirely of sustainable materials while offering high performance and innovative design.

The Sumo Diaper is a fitted cloth diaper that consists of a waterproof cover and absorbent inserts. The cover is sewn in such a way that a pocket is formed: this is where the absorbent pad is inserted to prevent slipping.

To further enhance the performance of this absorbent pad, the Sumo team partners with the viscose special fibre manufacturer Kelheim Fibres, who brings decades of experience from the hygiene sector, especially for sensitive applications where high absorbency is required (such as tampons). Together, Sumo and Kelheim Fibres have developed a high-performance absorbent pad that uses no fossil materials.

The basis are functionalised specialty viscose fibres with adapted cross-sections. Needle-punched / thermobonded nonwovens with a blend of specialty viscose and PLA bicomponent fibres were chosen to ensure the product's washability. PLA stands for polylactic acid made from natural and renewable raw materials. By combining nonwovens, usually found mainly in the single-use sector, with reusable products, Sumo and Kelheim Fibres have chosen a completely new approach.

Inside the pad, the speciality fibres from Kelheim score with their special properties: In the distribution layer (ADL), the trilobal cross-section of the Galaxy® fibre forms capillary channels that enable efficient and optimized liquid distribution and thus optimum use of the capacity of the absorbent core, offering the lowest rewet values.

In the absorbent core, the segmented hollow fibre Bramante stores liquid not only between but also inside the fibre. The liquid remains there even when pressure is applied to the construction, providing excellent rewet values. Bramante can absorb up to 260% of its own weight in liquid. Cotton only achieves values of around 50% here.

The innovative nonwoven construction with the speciality fibres from Kelheim performs significantly better in tests in terms of air permeability, liquid absorption and rewetting than commercially available solutions made of synthetic fibres or cotton in knitted structures, and has earned Sumo diapers a place among the finalists for the IDEA® Long-Life Product Achievement Award.

The launch is scheduled for the first of May.
