A new standard to combat plastic waste in forests

With DIN SPEC 35808, Hohenstein establishes testing standards for biodegradable tree shelters

With DIN SPEC 35808 “Tree Shelter for Forestry Applications,” the testing and research service provider Hohenstein, in collaboration with Rottenburg University of Forestry, as well as forestry authorities and industry partners, has established a clear framework for bio-based and fully biodegradable tree shelters. The pre-standard defines requirements and practical testing methods designed to reduce plastic waste in forests and strengthen the long-term protection of soil and the environment.

In forestry practice, tree shelters are widely used to protect young trees during their establishment phase. At the same time, however, a growing environmental concern is emerging: many plastic shelters remain in the soil after use and can break down into macro- and microplastics over time. Ambiguous definitions of “biodegradable” further add to the uncertainty in practice. Under what conditions does complete degradation occur—only in industrial composting facilities, or also under real conditions in forest soils? And when can removal of the shelters be safely omitted?

Binding criteria and a transparent framework

“The challenge is to develop materials that are sufficiently durable to reliably protect young trees while also being fully biodegradable,” explains Mihaela Szegedi, Project Manager at Hohenstein. “Our testing methods allow us to specifically identify such materials.” This is where DIN SPEC 35808 comes in: it establishes binding criteria and standardized testing procedures for tree shelters designed to fully biodegrade under realistic forest conditions. The aim is to create a transparent and reliable basis for sustainable product decisions. Hohenstein contributes its extensive research and testing expertise in the field of biodegradation. The testing procedures include analyses of bio-based content, harmful substances, biodegradability under forest conditions, and ecotoxicity. To ensure realistic conditions, real forest soils are used, defined in collaboration with forestry authorities.

Greater guidance for users and manufacturers

DIN SPEC 35808 is aimed at both forest owners and forestry operations, as well as manufacturers of tree shelters. For users, it provides a reliable basis for decision-making, as tested products can be demonstrably converted into natural components without leaving behind microplastics or harmful substances. At the same time, manufacturers benefit from clear testing and quality criteria for developing sustainable solutions and can position certified products more visibly in the market. With this new DIN SPEC, Hohenstein makes an important contribution to reducing macro- and microplastics in forest ecosystems. The goal is to establish materials that do not require removal after use because they biodegrade naturally—thereby strengthening the long-term protection of soils, plants, and the environment.

Hohenstein publishes 2025 Sustainability Report

The testing and research service provider Hohenstein has published its latest sustainability report, outlining key progress and strategic initiatives. The report focuses on ambitious CO₂ reduction targets, the company’s new mission statement and the systematic expansion of sustainable services for customers worldwide.

New DIN SPEC assesses environmental impact of textile fragments in soil

Textile products made from synthetic fibres, finished fabrics or dyed materials release fibre fragments into the environment at every stage of their life cycle. With the new DIN SPEC 19296, Hohenstein has developed a standardised testing method to analyse how these fragments behave in soil under natural conditions. Until now, little was known about their environmental behaviour or potential ecological effects once released.

Testing and research laboratory ensures safe and more sustainable products worldwide

For 80 years, Hohenstein has stood for independent testing, scientific expertise and practical solutions. Today, the testing and research service provider supports manufacturers and brands worldwide in making textiles, hardlines and medical devices safe, more sustainable and market-ready – thereby building trust among consumers. With an international presence and interdisciplinary expertise, Hohenstein supports its customers from production through to market launch, helping them navigate an environment of growing regulatory and societal demands.

The Or Foundation, adidas, BESTSELLER, H&M Group, and Inditex launch Apparel Recovery Coalition, responding to impacts of post-consumer textile exports

adidas, BESTSELLER, H&M Group, Inditex and The Or Foundation, with support from Circle Economy, unveiled the Apparel Recovery Coalition (ARC). The coalition will explore how producer responsibility systems can support circular pathways such as reuse, upcycling, recycling, and responsible waste management in countries that receive large volumes of exported secondhand apparel.

NEUMÜHLE launches mono-material hoodie designed for textile recycling

With the Circular Mono Hoodie, Zurich-based label NEUMÜHLE introduces a new essential designed around a single-material principle. The textile construction is cotton throughout, right down to the sewing thread. Entirely free from elastane, the hoodie launches as a Limited Drop for CHF 139. Take-back, collection and existing recycling partnerships complement its circular design.

EIM evolves into a new Environmental Intelligence to measure the impact of textile production

¿Do we really know the environmental impact behind a garment? Answering this question remains one of the textile industry’s major challenges. Garment production involves multiple stages, from yarn and fabric to final finishing, carried out by different players across the supply chain. Accesing reliable data from each process, connecting it and establishing a common language are essential to understanding a product’s true impact.

Mayer & Cie. Global gears up tor ITMA Asia 2026

Mayer & Cie. Global will focus on mattress fabric production at ITMA Asia, taking place in Shanghai from 20 to 24 November 2026. The company will showcase one of its flagship models for this application: the OVJA 2.4 EM. Joining the mattress fabric specialist will be an OV 3.2 QCe, presented at ITMA Asia in a configuration for knitting double-face fabrics in E40. This gives the OV 3.2 QCe a combination of capabilities rarely found in the market. The German textile machinery manufacturer will also introduce its new portfolio strategy and share updates from its development team at its Albstadt headquarters.
