At CIRAM, we perform carbon 14 analyses to determine the proportion of bio-based carbon in products as part of the OK biobased certification from TÜV AUSTRIA, applied to raw materials, intermediates, and finished products derived from renewable resources.

The OK biobased certification from TÜV AUSTRIA is a voluntary system for evaluating and certifying the bio-based content of a product.
It is based on carbon-14 analysis, which distinguishes carbon from renewable resources (recent biomass) from carbon from fossil resources. This method thus reliably determines the percentage of biobased carbon in a material.
The certification applies to products containing raw materials of natural origin such as starch, cellulose, or polymers biobased.
The classification is based on a system of 1 to 4 stars, directly linked to the measured carbon percentage biobased:
This system allows for a simple, comparative, and immediately understandable reading of a product's biobased level.

The OK biobased certification applies to a wide range of products derived from bio-based materials or natural polymers…, including:
It is used in the following processes:
It allows manufacturers to have an objective and standardized measurement of the content biobased, independent of supplier declarations.
Explore the areas of applicationAt CIRAM, we carry out the analyses necessary for OK biobased certification within a rigorous analytical framework, adapted to bio-based materials and industrial requirements.
Our approach is based on carbon-14 dating to ensure reliable, comparable, and actionable results for certification processes.
We bring you :
No, this is a voluntary certification system based on measuring the content biobased.
