One fundamental criterion for Testfakta Bio-based certification is that a high proportion of the product must be bio-based, compared with other, similar products. Another is that the product must meet essential environmental and performance requirements.
The minimum proportion of bio-based content required for certification varies among product categories.
Manufacturer’s details confirmed in analysis
Companies register their interest in certifying products, and it is the company’s responsibility to attest that the product meets the certification criteria. The product also undergoes an independent analysis in which its bio-based composition is measured. Confirmation of the manufacturer’s data concerning the proportion of bio-based content is thus obtained by a scientifically based, transparent method.
Special label for entirely plant-based products
For companies wishing to emphasise that their product contains no material of animal origin, there is a special label: Testfakta Bio-based from Plant. For this symbol to be used, the product’s bio-based content must be 100% plant-based, and this must be documented by the product owner. The technical analysis gives no answer as to whether the bio-based content is from a plant or animal source.
Packaging can also be labelled
Companies with certified products can choose to specify the proportion of bio-based material in their packaging as well.
The certification process, step by step:
Registration of interest
The owner of a product registers interest in certifying it, preferably using the form for the purpose accessed at the bottom of this page.
Specification of requirements
Based on product type, we contact the owner with specific certification requirements, including the necessary documentation, and a detailed account of the certification process and costs.
The product owner and Testfakta Bio-based sign an agreement on assessment and certification.
Assessment of the product
The documentation is investigated and the proportion of biomass in the product analysed. The review and analysis results are reported to the product owner.
If the product meets the certification requirements, an agreement is signed on the manufacturer’s right to label the product as Testfakta Bio-based.
Laboratory determination of bio-based composition
Bio-based products may contain renewable materials only, but usually consist of a mixture of renewable and fossil materials. The product composition is measured and ascertained by an independent testing laboratory. This analysis shows how much of the product content is bio-based. The number on the label refers to the percentage of bio-based content.
The scientifically based method of analysis is applicable to products and packaging of all kinds. The analysis provides information about the proportion of bio-based content in the final product, but not on how much bio-based content was used during production.
How the technical analysis is done
The bio-based content of a product can be analysed in a laboratory. This analysis is based on the carbon-14 dating method, which is used for such purposes as determining the age of archaeological finds.
The method determines the total quantity of organic carbon in the product analysed and the bio-based proportion of this carbon (according to standard ASTM D6866). If the measured proportion of bio-based carbon is 100%, it means that 100% of the carbon (in the product) comes from plants or animal by-products. If the proportion of bio-based carbon is found to be 0%, this means that all the organic carbon (in the product) comes from oil or other fossil resources.
Based on the proportion of bio-based organic carbon, the proportion of the product's total mass (total weight), or total carbon content (organic and inorganic carbon), which comes from renewable sources is calculated. The reporting of the proportion of bio-based content follows current guidelines and recommendations.
