1. Standardisation is an effort of industrial stakeholders to define criteria for the description of products and services. The idea is to ease the competition and the commercial growth by overcoming barriers that result from unclear or incompatible specifications.
2. The use of standards is voluntary, which means that it is within the sovereignty of a company to seek the compliance with a standard or not. In the latter case, however, it is not allowed to make the reference to the standard.
3. Certain European standards are called harmonised standards. This means that the European Commission mandated the European Standardisation Organisation CEN to elaborate the content of the standard.
BIOBASED
1. The standard “CEN/TS 16137:2011 Plastics – Determination of biobased carbon content” from the European Committee for Standardization (CEN), specifies the calculation method for determining the biobased carbon content in monomers, polymers and plastic materials and products, based on the 14C content measurement.
2.As the CEN/TS 16137 provides a standardised set of methods, it is currently the most important guideline for substantiating marketing claims regarding a material’s or product’s biobased carbon content.
3. Biobased carbon content is the variable describing the amount of biobased carbon (in relation to fossil-based carbon) contained in a material or product. It is measured via the 14C method that adheres to CEN/TS 16137 or ASTM 6866 standard. The 14C method assesses the overall carbon contained in a material or product and expresses the biobased carbon content as fraction weight (mass) or percent weight (mass).
COMPOSTABLE
1. If bioplastics have proven their compostability according to international standards, they can be treated in industrial composting plants. Plastic products can provide proof of their compostability by successfully meeting the harmonised European standard, EN 13432 or EN 14995. These two standards define the technical specification for the compostability of bioplastics products:
EN 13432:2000 Packaging:
- Requirements for packaging recoverable through composting and biodegradation
- Test scheme and evaluation criteria for the final acceptance of packaging
- This is a harmonised European standard linked to the European Directive on Packaging and Packaging Waste (94/62/EC). It allows for the presumption of conformity with essential requirements of the Directive. It has been translated and implemented in all the European Member States.
EN 14995:2006 Plastics:
-Evaluation of compostability
-Test scheme and specifications
-It broadens the scope of plastics when used in non-packaging applications. The EN 13432 applies when plastics are used for packaging.
