From the Sector

The Tuscan tannery Vesta Corporation has presented to its stakeholders a report outlining its current commitment and future objectives, with a view to innovating, safeguarding and fostering high-end leather material processing.

Ever since it was founded in 1966 in Ponte a Egola, the Tuscan hub for the production of leather for vegetable tanned soles, Vesta has been a supplier and partner of haute couture and sportswear brands, from lightweight calf and half-calf leather, to heavy leathers made with hind and rump hide, for leatherware and shoes.

To draft this Report, reference was made to the “Global Reporting Initiative Sustainability Reporting Standards” established by the Global Reporting Initiative (GRI). The information in the balance sheet refers to the year 2022 (from 1 January to 31December 2022). Wherever possible, data for the previous year are included, to allow for a comparison of data over time and to assess the trend of Vesta activities. Sustainability is an objective-driven process. This means that comparing data allows for concretely measuring the company’s progress, as it pursues this accounting process year after year.

The improvement actions already implemented by Vesta involve corporate responsibility from an environmental, social and governance perspective. An example are the improved heating and processing plants (which entails the construction of a new tumbling department based on 4.0 technology). This guarantees significant energy, water and economic savings. Along with numerous corporate certifications, the company has passed the Raw Material Traceability test with a score of EXCELLENT, as well as the Carbon and Water footprint analysis.

As confirmation of its commitment to improving corporate performance levels, Vesta has been upgraded from BRONZE (2020) to GOLD in 2023, as assessed by the Leather Working Group (which measures leather manufacturers’ environmental performance for ecological production and for a systemic management of quality, environmental, safety and ethical factors).

Becoming energy-independent is a major step in the pipeline, involving the installation of a photovoltaic plant. This is complemented by the implementation of a project aimed at totally compensating its CO2 emissions for the year subject to accounting and certification. This neutrality will be achieved through the acquisition of credits deriving from projects certified by the United Nations. For example, with the construction of an important hydro-electric plant to which Vesta is contributing. With regard to production, corporate research is currently focused on developing solutions to reduce water and energy use. It is also implementing circular trends by adopting an increasing number of bio-based products, to guarantee the most sustainable end-of-life and waste management for its products.

Textiles are a given in civil engineering: they stabilize water protection dams, prevent runoff containing pollutants from landfills, facilitate the revegetation of slopes at risk of erosion, and even make asphalt layers of roads thinner. Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Depending on humidity and temperature, natural fiber materials can degrade in the soil in a matter of months or even a few days. In order to significantly extend the degradation time and make them suitable for geotextiles, the Denkendorf team researches a protective coating. This coating, based on lignin, is itself biodegradable and does not generate microplastics in the soil. Lignin is indeed biodegradable, but this degradation takes a very long time in nature.

Together with cellulose, Lignin forms the building materials for wood and is the "glue" in wood that holds this composite material together. In paper production, usually only the cellulose is used, so lignin is produced in large quantities as a waste material. So-called kraft lignin remains as a fusible material. Textile production can deal well with thermoplastic materials. All in all, this is a good prerequisite for taking a closer look at lignin as a protective coating for geotextiles.

Lignin is brittle by nature. Therefore, it is necessary to blend the kraft lignin with softer biomaterials. These new biopolymer compounds of brittle kraft lignin and softer biopolymers were applied to yarns and textile surfaces in the research project via adapted coating systems. For this purpose, for example, cotton yarns were coated with lignin at different application rates and evaluated. Biodegradation testing was carried out using soil burial tests both in a climatic chamber with temperature and humidity defined precisely according to the standard and outdoors under real environmental conditions. With positive results: the service life of textiles made of natural fibers can be extended by many factors with a lignin coating: The thicker the protective coating, the longer the protection lasts. In the outdoor tests, the lignin coating was still completely intact even after about 160 days of burial.

Textile materials coated with lignin enable sustainable applications. For example, they have an adjustable and sufficiently long service life for certain geotextile applications. In addition, they are still biodegradable and can replace previously used synthetic materials in some applications, such as revegetation of trench and stream banks.

Thus, lignin-coated textiles have the potential to significantly reduce the carbon footprint: They reduce dependence on petroleum-based products and avoid the formation of microplastics in the soil.

Further research is needed to establish lignin, which was previously a waste material, as a new valuable material in industrial manufacturing processes in the textile industry.

The research work was supported by the Baden-Württemberg Ministry of Food, Rural Areas and Consumer Protection as part of the Baden-Württemberg State Strategy for a Sustainable Bioeconomy.

INDA, the Association of the Nonwoven Fabrics Industry, revealed the three finalists that will compete for the Hygienix Innovation Award™. Glatfelter, Mundeo, and Sequel will present their new absorbent hygiene products to senior-level leaders at Hygienix, Nov. 13-16, New Orleans, Louisiana.

Here is a summary of the finalists’ products:

Glatfelter: GlatPure™
GlatPure™ is a range of bio-based absorbent hygiene components derived from renewable materials. This product range consists of a variety of plant-based and natural topsheets, an acquisition distribution layer, an absorbent core, a newly improved backsheet, and a landing zone. Crafted from 100% renewable fibers and biodegradable materials, and enriched with bio-based binders, GlatPure™ stands as the industry’s first fully functional, fossil-fuel free range of solutions.  

Mundao: Diap’Earth®
From nature to nature: Mundao brings to market DIAP’EARTH®, an industrially compostable baby diaper. This diaper provides a circular solution to the AHP waste issue. Ecoconception (DIAP’EARTH is a bio-based & plastic free diaper) makes it possible to compost the diaper in an industrial composting facility to turn it into carbon where it can become fertilizer for soil. DIAP’EARTH has been successfully composted in major French cities.

Sequel: The Sequel Spiral™ Tampon
The Sequel Spiral™ Tampon features a proprietary spiral design that is engineered to be more fluid mechanically efficient, meaning it is designed to absorb more evenly and not leak before it’s full. In August 2023 the Sequel Spiral™ Tampon received clearance from the United States Food and Drug Administration (FDA) as a medical device and the company will now begin a series of consumer trials, with broad availability expected in Q1 of 2024.

The winner of the Award will be announced at the end of the event, Thurs., Nov. 16th, at 11:30 am. Last year’s award recipient was Pads on a Roll™ by Egal Pads. Pads on a Roll is a wrapped super-thin absorbent period pad that dispenses like toilet paper in public bathroom stalls, preventing the personal embarrassment of not having a menstrual product when needed.

Conference Highlights
In addition to the award presentation, the Hygienix™ conference will focus on consumer-centric innovations, the circular economy, raw material advancements in sustainability, opportunities for advanced recycling in absorbent hygiene, optimizing the packaging footprint, new approaches for odor control, and market trends and drivers. Plus, INDA’s Government Affairs office will be in attendance to provide insights into recent regulatory and legislative issues. Participants can learn about how the current political landscape could affect the nonwovens industry.

UK’s Optima 3D is delivering its weaving technology to the USA, for installation at the University of Maine’s Advanced Structures and Composites Center (ASCC).

The 3D weaving system consists of an Optima 3D Series 600 shuttle weaving machine with an integrated 2,688-hook Stäubli SX jacquard and harness. It is also complemented by Optima’s compact warp delivery creel and an associated pirn winder for shuttle bobbins and a spool winder for creel spools.

Optima’s looms offer many advanced features over conventional weaving machines, particularly in terms of versatility, as a result of the comprehensive use of digital control systems allowing rapid parameter and sequence changes, coupled with an innovative shuttle system.

The ASCC is certainly no stranger to advanced technology, or indeed ambitious composite projects – in 2019 it received no less than three Guinness World Records, for the world’s largest prototype polymer 3D printer, the largest solid 3D-printed object, and the largest 3D-printed boat. In its latest project it has further introduced BioHome3D – the first 3D-printed house made entirely with bio-based materials developed in a partnership with Oak Ridge National Laboratory. The 182-square-metre prototype features 3D-printed floors, walls and roof which are fully recyclable and highly insulated with 100% wood insulation and customisable R-values. Construction waste was nearly eliminated due to the precision of the printing process.

KARL MAYER GROUP will be presenting a WEFTTRONIC® II G at the ITMA with new features and upgrades for greater efficiency. This warp knitting machine with weft insertion produces lattice structures from high-strength polyester, which are firmly established in the construction industry in particular. With a working width of 213", it offers productivity and further advantages through design innovations. New features include weft thread tension monitoring, management and the new VARIO WEFT laying system. The component for the weft insertion aims at maximum flexibility. It allows the patterning of the weft yarn to be changed quickly and easily electronically, without mechanical intervention during yarn insertion and without limits on repeat lengths. In addition, there is less waste.

The KARL MAYER GROUP also supports its customers with well thought-out Care Solutions. The new support offers include retrofit packages for retrofitting control and drive technology for weft insertion and composite machines, and service packages that bundle various services. These include machine inspections and the replacement of all drive belts. The customer benefits from fixed prices that cover the costs of technician assignments, various discount options and transparent services.

A new solution for the vertical greening of cities is presented from the field of application for technical textiles. The core of the innovation is a grid textile produced on warp knitting machines with weft insertion by KARL MAYER Technische Textilien GmbH. The knitted lattice fabric is made of flax. It is used as a climbing aid for fast-growing plants, and after the greening phase, in autumn, it can be recycled together with these plants as biomass in pyrolysis plants to produce electricity and activated carbon. In summer, the planted sails lower the ambient temperature through evaporation effects. In addition, photosynthesis creates fresh air and binds CO2. Other important advantages are low soil requirements and flexible placement in public spaces. The greening system was developed by the company Micro Climate Cultivation, OMC°C, with the support of KARL MAYER Technische Textilien.

The KARL MAYER GROUP will also be exhibiting a sustainable composite solution made from natural fibres. The reinforcing textile of the innovative lightweight material is a multiaxial non-crimp fabric, which was also produced from the bio-based raw material flax on a COP MAX 4 from KARL MAYER Technische Textilien. The boatbuilding specialist GREENBOATS uses natural fibre composites to achieve sustainable products. The fact that it succeeds in this is shown, for example, by the Global Warming Potential (GWP): 0.48 kg of CO2 per kilogram of flax reinforcement compares with 2.9 kg of CO2 per kilogram of glass textile.

Stahl announces that its near-term greenhouse gas (GHG) emissions reduction targets have been validated by the Science Based Targets initiative (SBTi). Stahl is one of the few coatings companies to receive this validation. To date, 145 companies in the chemicals sector have submitted an emissions reduction target to the SBTi, of which 61 have had their targets validated.

Stahl’s science-based targets, which reflect the company’s commitment to the 2015 Paris Agreement goals, are:  

• Stahl Holdings B.V. commits to reduce absolute scope 1 & 2 GHG emissions 42.0% by CY2030 from a CY2021 base year.*
• Stahl Holdings B.V. commits to reduce absolute scope 3 GHG emissions 25.0% by CY2030 from a CY2021 base year.

The SBTi classifies emissions reduction targets according to two potential temperature pathways: 1) limiting global temperature rises to 1.5°C above pre-industrial levels, and 2) limiting temperature rises to well below 2°C. The SBTi has determined that Stahl’s Scope 1 and 2 target is in line with a 1.5°C trajectory, while Stahl’s Scope 3 target has been validated in line with the well-below 2°C pathway.

Maarten Heijbroek, CEO of Stahl: “The validation of our Scope 1, 2, and 3 emissions reduction targets by the SBTi is an important milestone on our ESG journey as we strive to limit our contribution to global warming, in line with the Paris Agreement. Our targets are ambitious, and rightly so. Realizing our goal to help create a more responsible coatings value chain starts with being accountable for our own environmental impact, and taking concrete steps to reduce our emissions wherever possible.”

A clear strategy to reduce GHG emissions
Stahl’s approach to realizing its near-term emissions reduction targets is outlined in the company’s Environmental, Social, and Governance (ESG) Roadmap to 2030. This strategy defines the specific metrics against which progress on the company’s ESG commitments will be measured.

Stahl’s Scope 1 and 2 GHG emissions reduction targets, as submitted to the SBTi, cover emissions from all manufacturing sites where Stahl products are produced, as well as the company’s largest non-manufacturing locations. Stahl aims to lower these emissions by reducing its overall energy consumption and increasing the use of renewable energy at its sites. To achieve this, the company plans to increase its self-generated electricity capacity (using solar power, for example) and continue investing in more energy-efficient equipment.

Stahl plans to reduce its Scope 3 upstream emissions primarily by replacing fossil-based raw materials in its products with renewable alternatives, such as bio-based and recycled-based feedstocks. In addition, the company plans to introduce more low-impact raw materials into its product design.

* The target boundary includes biogenic land-related emissions and removals from bioenergy feedstocks.

The international association that will manage the Single-Entry-Point (SEP) of the BIONANOPOLYS project has been formally constituted and will be able to support companies across the European Union in the market introduction of bionanomaterials through technical, legal, regulatory, safety, economic and financial support services.

The SEP was established as an AISBL (non-profit entity) on 17 February 2023 in the framework of the European project BIONANOPOLYS, funded by the Horizon 2020 programme. The technical director of ITENE and coordinator of this project, Carmen Sánchez, is the president of this association in which representatives of other project partners also act as directors. Specifically, the CTP (Centre Technique du Papier) from France; CIDAUT (Fundación para la Investigación y Desarrollo en Transporte y Energía), from Spain; CENTI (Centre for Nanotechnology and Smart Materials), from Portugal, and the law firm Gil & Robles - San Bartolome & Associés, from Luxembourg.

The BIONANOPOLYS SEP will reduce the risks and barriers to the commercial exploitation of bio-based materials and polymeric bionanocomposites with nanotechnology and accelerate market penetration and innovation processes. SMEs, large companies, and potential customers who are users of the BIONANOPOLYS OITB (Open Innovation Test Bed) will be able to access the services offered by the project partners through this entity, which will act as a one-stop shop, at affordable costs and conditions.

The test bed consists of 14 enhanced pilot plants and complementary services to support technological and commercial breakthroughs. Collaboration between all the partners that make up BIONANOPOLYS and access through the SEP allows joint access to all the services offered by the partners and helps to drive collaborative open innovation.

Call for access to the BIONANOPOLYS OITB
The SEP and the project partners will be in charge of evaluating the projects submitted to the BIONANOPOLYS platform once the open call launched last February to select five projects from different European countries that will be able to access its services free of charge to develop, test or scale-up bionanomaterials in the BIONANOPOLYS OITB closes.

Companies wishing to access the services to develop or test nanomaterials can submit their applications until 30 April.

The BIONANOPOLYS test bed could benefit companies involved in the production of biopolymers, cellulose paper, nonwovens, foams, or coatings, as well as the packaging, agriculture, food, cosmetics, pharmaceuticals, hygiene, textiles and 3D printing sectors.
