From the Sector

After the C.L.A.S.S. recent evolution of its communication tools, they are really pleased to introduce Circular Systems as new C.L.A.S.S. Material Hub partner.

Circular Systems is a California based materials science company, focused on creating a net positive impact on environment, society and economy through innovation. Its circular plus regenerative technologies provide systemic solutions for transforming waste into valuable fibre, yarns, and fabrics for the fashion industry.

Textile waste and agriculture residues are a huge problem, often burned, left to rot in the fields, or sent to landfills creating massive amounts of CO2. Circular Systems is looking at these waste streams as valuable resources, turning problem into a solution by converting them into high value materials for the fashion industry. The “Lightest Touch™“ philosophy, defines their mission to retain maximum amount of embedded energy in waste inputs while creating the “highest-value outputs” with the lowest impacts. Integration of these technologies into global supply chains is key without compromising quality, thus extending the life cycle of these materials.

Circular Systems has three waste-to-fibre platforms that offer an efficient management of textile and agricultural waste:

• The Agraloop™ refines natural fibers derived from agricultural crops into textile-grade fiber called Agraloop™ BioFibre™.  A NEW Natural Fiber mindfully sourced for circularity. With our specialized processing technique, cellulose fiber from stems and leaves are purified into soft fiber bundles ready to spin into yarns. The Agraloop™ processes leftovers from various food and medicine crops including, oilseed hemp/flax, CBD hemp, banana, and pineapple.
• Texloop™ Recycling produces high-quality GRS (Global Recycled Standard) certified recycled cotton fibre called RCOT™. Texloop™ preserves fiber quality for the next generation of recycled materials and blends with GOTS (Global Organic Textile Standard) certified organic cotton and Canopy approved man-made cellulosics to create near virgin quality yarns for knitting and weaving.
• Orbital™ hybrid yarns create high-quality materials with high-performance, using organic and recycled fiber inputs. Orbital's patent-pending technology produces inherent wicking and fast dry performance materials, even with 50%-70% natural fiber composition, eliminating the need for chemical finishes to create high-performance fabrics.

All Circular Systems yarns are GRS, OCS and/or GOTS certified and are in the process of developing  their own Crop Residue Standard with Textile Exchange that would relate to the Agraloop™ platform technology.

Archroma announced the launch of EARTH SOFT, a new softening system for textile and fashion applications, based on Archroma's latest innovation, a vegan silicone softener, Siligen® EH1, with 35% plant-based active content.

Siligen® EH1 is the latest addition in the plant-based innovations developed by Archroma in recent years, such as EarthColors® dyes and Appretan® NTR binders, as alternatives offered to manufacturers and brands looking to reduce the use of fossil fuel based ingredients without compromising performance.

The range has been developed in line with the principles of “The Archroma Way to a sustainable world: safe, efficient, enhanced, it’s our nature”. More than 35% of the Siligen® EH1 softener's active content is based on plant-based, renewable raw materials. In addition, the product features ultralow cyclic siloxanes (D4, D5, D6) which are classified by the European Chemicals Agency as “Substances of Very High Concern” due to their very persistent and bioaccumulative properties.

Siligen® EH1 is ideally suited for shirts, underwear, sportswear, towels, bed sheets, etc. as it provides an excellent wearing comfort by supporting a good moisture transportation and delivering a smooth and soft touch.

The new softener, and the EARTH SOFT system which also includes a Hydroperm® wicking agent to boost hydrophilic properties on synthetic and blended fibers, can be applied on all natural and synthetic textile fibers.

Siligen® EH1 is suitable for both woven and knitted articles. It can be applied by padding process, as well as by exhaust process as it shows a very good shear stability and a low foaming profile. It can be used on white articles and those treated with optical brighteners, as it doesn’t cause thermomigration nor phenolic yellowing.

Paul Cowell, Head of Competence Centers for Brand & Performance Textile Specialties at Archroma, comments: “The new EARTH SOFT system based on Siligen® EH1 softener adds to our growing portfolio of innovations based on natural and renewable plant-based resources. This new breakthrough innovation by Archroma helps us and our partners in the textile and fashion industry to minimize our dependence on petroleum fossil fuel products.”

On 27 November 2021, the Scientific Award for International Sustainable Aviation and Energy Society (SARES Award) was awarded to Professor Dr Thomas Gries from the Institut für Textiltechnik of RWTH Aachen University. The award ceremony took place during the closing ceremony of the International Symposium on Sustainable Aviation (ISSA) in a hybrid format online and simultaneously at Kasetsart University, Bangkok, Thailand.
 
With the award, the committee recognised the ongoing contribution of Pro-fessor Gries and the Institut für Textiltechnik to the digitisation and bio-transformation of the textile sector, as well as the Institute as a place of innovation for sustainable aviation.

Examples of this include the development of 3D braided ceramic matrix composite components for aircraft engines, which were researched together with partners in a Horizon 2020 project (EU project AllOxITD). The ongoing Chrysomallos research project as another example, funded under the national aeronautics research programme in Germany, aims to develop a completely new and sustainable high-performance insulator for aircraft cabins based on aerogels. These have a significantly lower weight than the glass fibre mats used up to now, while providing the same insulation performance, and solve the problem of the previously high manufacturing costs of aerogels. The aim of the project is to develop an insulation material with reduced density (reduction of more than 20 percent). To this end, a new type of insulation material based on aerogel is to be developed. The basis is an aerogel fleece (0.06 W/mK at 28 kg/m³), which has already been developed as part of a dissertation at the Institut für Textiltechnik of RWTH Aachen University (Mroszczok, J.: 2019).

The aviation industry is one of the fastest growing industries in the world. Due to this fact and its importance for society and the global economy, it needs to make special efforts towards sustainability. The ISSA, an international multi-disciplinary symposium, aims to address current issues in aviation such as improving aircraft fuel efficiency, promoting the use of biofuels, minimising environmental impact, mitigating greenhouse gas emissions and reducing engine and aircraft noise. ^

Through the award, SARES honours scientists and researchers whose work on sustainable aviation issues has made an important contribution at the international level. The selection is based on the scientific publications of the applicant or nominee, the h-index, i.e. the key figure for the worldwide perception of a scientist in professional circles, the project topics and the project results.

Sappi has approved an investment in Kirkniemi Mill in Lohja, Finland which enables a switch in its energy sourcing to renewable bioenergy. With this investment the mill’s direct fossil greenhouse gas emissions will reduce by ca. 90 percent, which is equivalent to 230 000 tons of carbon dioxide annually.

The project, set for completion in early 2023, will contribute significantly to Sappi Europe’s decarbonisation roadmap by exiting coal at one of its last facilities partially using this fuel type. Biomass will then be used in Kirkniemi’s multi-fuel boiler, built in 2015. The move advances Sappi towards its 2025 targets which include reducing specific greenhouse gas emissions (scope 1 and 2) by 25 percent and increasing renewable energy share to 50 percent in Europe compared to 2019.

The investment will establish the equipment needed to receive, store and handle woody biomass like the bark, sawdust and wood chips used for biofuel production. Such biomass types are by-products from the forest-based industry and utilising them for energy production derives further value from the forest resource.

In addition to increasing share of renewable energy, Sappi’s mills are also focused on reducing energy consumption. Sappi Kirkniemi Mill is party to Finland’s National Energy Efficiency Agreement and consistently reaches their energy saving targets. Kirkniemi’s ISO 50001 certification provides further evidence of the mill’s systematic improvement in energy efficiency.

With its resource-saving dyeing technology, We aRe SpinDye takes place in H&M's latest Innovation Stories collection called Co-exist.

The use of We aRe SpinDye's technology contributes to reducing both water consumption and CO2 emissions, which in turn leads to a lower impact on the world's ecosystem and creates conditions for our co-existence with nature.

Up to 24% of a garment's entire climate footprint occurs during dyeing. We aRe SpinDye's technology can reduce the consumption of the earth's resources in textile production. On average, the reduction of water is -75%, chemicals -90% and energy consumption and CO2 emissions -30%.

In just one year, the clothing industry uses 9 billion cubic meters of water (which is in line with the annual need for drinkingwater for the entire population of our planet) and 168 million tons of process chemicals to dye fabrics. We aRe SpinDye now hopes that more players in the industry will pay attention to the ways that are available when it comes to resource-efficient dyeing process and quickly implement this technology in their production.

"The enormous resource consumption in the dyeing process is a global problem that must be addressed on a broad front. It is therefore inspiring to work with major brands with an organization that is sensitive to cutting-edge expertise and at the same time shows a willingness to work together to achieve common goals", says Andreas Andrén, CEO of We aRe SpinDye.

10 years after the installation of the photovoltaic plant in the production units in the Biellese region, the Marchi & Fildi Group takes stock of the operation and publishes the data on energy produced, consumed, and fed back into the grid.

The photovoltaic plant owned by the Group is made up of 11,385 modules divided between the three facilities in Biella (Production), Cerrione (Dyeing mill) and Verrone (Logistics), which in total cover a surface of 16,515 sq.m.

The balance to be drawn from these 10 years is a positive one: in total 22,974,828 kWh have been produced, of which 7,292,027 kWh have been used in company activities, with a saving in energy costs of approximately €1m over 10 years.  

The energy kWh produced and not used by the company was fed back into the grid and corresponds to the average annual consumption of around 4630 families.*

The Marchi & Fildi Group has always been committed to rationalising electric energy consumption with the aim of contributing towards an eco-sustainable development without compromising the rate of production and the ability to grow. In addition to producing its own electric energy, over the years, the company has also achieved an increasing number of Energy Efficiency Titles (TEE), otherwise known as white certificates. In 2021, 138 TEEs have been awarded as a result of such interventions as the introduction of LED lighting and the optimisation of the production processes which, while still as efficient as before, permit the company to reduce the electric energy consumption of the machinery.

*In the meter class for the range of 3kW to 4.5 kW, the average consumption for residential properties is the equivalent of 3,382 kWh (source: Arera Relazione annual state of services for the year 2020). The calculations are the results of an internal study conducted by the Marchi & Fildi Group.
