NF EN 13432 Testing of compostability for textile fibres
The NF EN 13432 standard sets out the requirements for ensuring that packaging and other products can be safely composted under industrial composting conditions. This service focuses on testing textile fibres to ensure they meet these stringent compostability criteria.
Compostable textiles are a crucial part of sustainable fashion, aiming to reduce waste by allowing garments to decompose into natural elements after use. The NF EN 13432 standard ensures that when such textiles reach the end of their lifecycle, they can be safely and effectively composted without contributing harmful substances to the environment.
To achieve this, textile fibres must pass a series of tests designed to evaluate their ability to biodegrade under industrial composting conditions. These tests include measuring the degradation rate in industrial compost, ensuring that the end-of-life material does not release harmful residues into the soil, and verifying that the final product is stable enough for composting.
The testing process involves several key steps. First, the textile fibres are prepared according to specific protocols outlined in NF EN 13432. This includes ensuring consistent moisture content and temperature during incubation periods. The samples undergo degradation tests at temperatures of approximately 58°C for a minimum of six months.
At regular intervals throughout this period, the samples are weighed and analyzed to determine their mass loss. Simultaneously, laboratory compost is prepared according to NF EN 13432 specifications, ensuring it meets all necessary standards regarding pH levels, C:N ratios, and other essential parameters that simulate industrial composting conditions.
The final step in the testing process involves analyzing the residuals left after degradation. These residues are tested for their ability to support microbial growth and determine whether any harmful substances remain. If the textile fibre passes these rigorous tests, it is deemed compliant with NF EN 13432 standards, allowing manufacturers to label their products as compostable.
The importance of this testing cannot be overstated, especially in an era where sustainability is increasingly at the forefront of consumer and industrial consciousness. By adhering to these strict standards, companies can contribute significantly to reducing textile waste while promoting a circular economy model that supports environmental health.
