RadiciGroup: circular fashion along the entire supply chain
The manufacturer of synthetic fibers and yarns, RadiciGroup, Gandino/Italy, is participating in the “Monitor for Circular Fashion”, an innovative Italian project launched by the SDA Bocconi School of Management, Milan/Italy, and Enel X, Rome/Italy, with the objective of creating an Italian fashion community through the collaboration of the supply chain players most committed to the sustainability agenda.
The initiative aims to assess the state of maturity of the circular economy in the Italian fashion industry, to define an ambitious plan integrating circularity in fashion and to develop new concrete and measurable circular economy solutions through the sharing of best practices, with the goal of making the strategic fashion sector ever more sustainable.
Ralph Lauren: zero wastewater cotton dyeing system
The water used for fabric dyeing alone is pollution about 20% of the world’s wastewater. Delivering the world’s first scalable zero wastewater cotton dyeing system, Ralph Lauren Corp., New York, NY/USA, has established Color on Demand, a multi-phased system.
Designed to help address water scarcity and pollution caused by cotton dyeing, Color on Demand is a new system composed of a set of technologies that will enable the recycling and reuse of all water from the dyeing process, establishing the world’s first scalable zero wastewater cotton dyeing system. In addition to significant water savings, this system reduces the amount of chemicals, dye, time and energy used in the cotton dyeing process. This will enable significantly shorter lead times for making product color decisions.
To implement this approach, Ralph Lauren brought together 4 leading innovators in their respective fields, including Dow Chemical Co. Midland, MI/USA, a leader in materials science; Jeanologia, Paterna/Spain, a leader in sustainable solutions for garment and fabric finishing, with high expertise in garment dyeing and close loop water treatment systems; Huntsman Textile Effects, Singapore, a global chemicals company specializing in textile dyes and chemicals; and Corob SpA, San Felice/Italy, a global technology leader in dispensing and mixing solutions, to reimagine each stage of the coloring process and join this shared mission to create a more sustainable and efficient system for cotton dyeing.
As part of the first phase of Color on Demand, Ralph Lauren optimized the use of Ecofast Pure Sustainable Textile Treatment, a pre-treatment solution developed by Dow for cotton textiles. When used with existing dyeing equipment, Ecofast Pure enables the use of up to 40% less water, 85% fewer chemicals, 90% less energy and a 60% reduction in carbon footprint compared to traditional cotton dyeing processes. Ralph Lauren is integrating this process into its supply chain and will launch product using this technology later this year.
ZKS: climate neutral yarn
Avoiding, reducing and, if there is no other way, offsetting the emission of climate-damaging CO2. With this approach, Zwickauer Kammgarn GmbH (ZKS), Zwickau/Germany, a company of Peppermint Holding GmbH, Berlin/Germany, offers a complete service for a completely climate-neutral yarn.
For each customer, the exact carbon footprint of the yarn delivered to them can also be calculated: along the entire supply chain starting from the raw material.
The goal is to constantly reduce and avoid the environmental impact of products, raw materials, production processes and logistics. Therefore, bio-based, biodegradable and recycled raw materials are increasingly used. This should lead to CO2-neutral supply chains.
If technical limits are reached, the unavoidable emissions are offset in order to offer a climate-neutral product.
International Cotton Conference: latest trends around cotton
450 participants from 32 countries attended the 35th International Cotton Conference on March 17-18, 2021, which this year was organized by the Bremen Cotton Exchange, Bremen/Germany, and the Faserinstitut Bremen e.V. (FIBRE), Bremen, as a hybrid event. 90 speakers and panelists with topical presentations as well as discussion panels ensured a lively exchange of information on all aspects of cotton.
The conference sessions were divided into 2 parallel lecture strands, intended for visitors with different information interests. In the “Conceptual Track”, it was all about conveying information on a more political, strategic range of topics. These were, for example, sustainable cotton cultivation, transparency in the supply chain and corporate responsibility. In the more subject-specific “Technical Track”, the leading role was given to technological advances in cotton cultivation through digitalization, increasing yields, improving fiber quality, quality testing and standardization.
Alongside the sessions, there were poster presentations or poster talks and exchange discussions with experts. These partly followed on from the content of the lectures or extended the range of experience with informative impulses on other subjects. To achieve this, special virtual rooms were set up on the conference platform, which were open to participants during the conference for communication purposes of all kinds.
The next International Cotton Conference will be held on March 30-31, 2022, the year of the 150th anniversary of the Bremen Cotton Exchange.
