All Organic?

Hohenstein uses a new quantitative method to detect the type and extent of genetic modifications in organic cotton directly during the process chain.

There has been a sharp rise in demand for organic cotton products. Compared to conventionally grown cotton, the cultivation of organic cotton requires the renunciation of genetically modified seeds, chemical pesticides or fertilisers. Nevertheless, genetic modifications are repeatedly found in textiles that are falsely labelled with organic claims. Often, available certification systems are not backed up by lab testing. At best, they only take random seed samples. Textile testing specialist, Hohenstein, has developed an assessment method specifically for cotton. This new DNA analysis method makes it possible to ascertain the amount of genetically modified cotton contained in products. This is good news for textile industry stakeholders who will be on the safe side in terms of quality control and labelling of organic cotton products.

First step: qualitative screening and identification. Second step: quantification of genetically modified cotton.

For qualitative screening, Hohenstein experts had developed molecular biological detection systems to make clear yes/no statements about genetically modified cotton. Testing can be applied to all kinds of materials, from raw cotton to chemically untreated yarns and fabrics. In addition, Hohenstein is one of only a few laboratories in the world accredited to test for GMOs in accordance with the ISO/IWA 32:2019 protocol. Its method provides reliable evidence of the presence or exclusion of genetic modification in cotton textile precursors.

Manufacturers, brand owners, retailers and certification bodies all benefit from analytical evidence – all the way to the end product. Consumers can rest assured that no GM cotton has been detected in the articles they buy. © Hohenstein

Once qualitative proof of genetic modification is obtained, Hohenstein experts begin quantifying the type and extent of the genetic modifications. To do this, they use DNA analysis to search for different cotton lines known to contain genetic alterations and quantify the proportion. Only by pinpointing individual genetic modifications and quantifying the extent of modification is it possible to provide precise information on whether there is an extremely small proportion of contamination, or whether larger proportions of GMOs have been mixed in. This offers clear benefits to manufacturers, brand owners and retailers when it comes to supply chain transparency and fraud prevention.

A smarter way to verified Chemical Compliance

Hohenstein and GoBlu Drive Innovation in Sustainable Supply Chain Management As regulatory demands, customer expectations, and sustainability goals continue to grow, the ability to manage chemical compliance and data across complex supply chains has become critical. Hohenstein and The BHive® by GoBlu are initiating a strategic partnership to enhance chemical management in the textile sector. The collaboration delivers more than just a service – it provides an integrated, future-ready solution for brands, manufacturers and suppliers seeking trusted chemical management and credible sustainability.

Hohenstein achieves GLP Certification for Medical Device Testing

Since the middle of July, the testing service provider Hohenstein has been certified to conduct medical device testing in accordance with the internationally recognised Good Laboratory Practice (GLP) standard. This certification comprehensively covers chemical, physical and biological safety testing of medical devices.

Hohenstein supports Global Textile Scheme Initiative

Global testing and research provider Hohenstein has acquired shares in Global Textile Scheme GmbH (GTS). In this way, Hohenstein aims to support GTS in harmonizing and automating data exchange along the entire supply chain. The aim of the GTS initiative is to create an international standard for handling structured product data in the textile and apparel industry.

Hohenstein releases 2024 sustainability report

Responsible action is a defining value for Hohenstein, a global testing and research provider. Their 2024 Sustainability Report provides transparency through documented progress and detailed insights into how sustainability is embedded. It covers both the existing sustainability measures at the German headquarters and the company's goals for 2025 and beyond. The direct and indirect greenhouse gas emissions (Scope 1, 2 and 3) of all its locations worldwide were recorded for the first time.

Sustainable athletic wear made from bio-based Polyethylene

Conventional sports textiles made from petroleum-based synthetic fibres are to be replaced in the future by sustainable, bio-based, cooling textiles. Polyethylene, previously used mainly in the packaging industry, is thus qualified for use in textiles and, as a bio-based drop-in solution, offers a cost-effective, sustainable alternative for the future.

Innovation center for textile circular economy inaugurated

Just over eight months after the foundation stone was laid, the new Innovation Center for Textile Circular Economy was officially inaugurated today at TITK Rudolstadt. Thuringia's Minister President Mario Voigt, TITK Director Benjamin Redlingshöfer, and other guests of honor cut the ribbon to the modern building complex and viewed the premises, which are now ready for occupancy. The “DICE – Demonstration and Innovation Center for Textile Circular Economy” is TITK's largest single investment to date. The Free State of Thuringia supported the total cost of €11.5 million with €8 million in GRW and FTI funding.

Sustainable design of Geosynthetics and roof underlayments made from recyclates

Is it possible to recover plastic recyclates from previously unused waste streams in order to produce high-quality fibers and films? How can bio-based polymer fibers be manufactured so as to allow adjustable biodegradability? These are the questions being addressed by researchers from the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE in the Zirk-Tex project.
