Once a textile has become obsolete, it can be put back into the cycle as a second-hand product, through downcycling, as an upcycling product or through recycling. Otherwise it will be disposed of - through thermal use, landfilling or composting.
The biodegradation (biodegradability) test established by Hohenstein assesses the degradation of textile products over a defined test period and through controlled soil burial. These soil burial tests are based on international standards that determine the decomposition and degradation behaviour of materials.
In this way, you can transparently communicate the environmental impact of your textiles to the outside after the end of use - demonstrating that your responsibility spans the entire usage cycle.
Our tests are especially suited for
- Textile manufacturers and finishers
- Textile retailers (only for examinations of biodegradability)
The Hohenstein test setup was developed in accordance with the following standards:
- DIN EN ISO 11721-1: Textiles - Determination of resistance of cellulose-containing textiles to micro-organisms - Soil burial test - Part 1: Assessment of rot-retardant finishing
- DIN EN ISO 846: Plastics - Evaluation of the action of microorganisms on plastics
- DIN EN 13432: Requirements for packaging recoverable through composting and biodegradation
On this basis, we offer you individual tests that are designed to meet your requirements.
- The mass loss of the textile:
the decay process of a product by micro-organisms like fungi and bacteria in combination with oxygen in the soil is examined.
- The ecotoxicological safety of the textile:
cress and earthworm tests are used to test the impact on the environment.
The soil burial tests take place under standardised conditions. With this, you can determine whether your textiles are buried
- under standardised laboratory conditions or
- under outdoor conditions (exposed to the climate).
- Product optimisation on the basis of our results
- Labelling of biodegradable textile products by a Hohenstein Quality Label (B2C) or by a Hohenstein certificate (B2B)
- Determination of the risks of your product for the environment
- In the area of B2B:
- Objective and reliable evaluation of the biodegradability
- Quality assurance based on ecotoxicological considerations
- In the area of B2C:
- Marketing tool (advertising impact)
- Support for argumentation or purchasing decision to consumers
