The role of recognized laboratories and certifying bodies

Category: Developments in laws and regulations on plastics

The demand for bioplastics is increasing exponentially, and a wide range of biodegradable and/or compostable products is now available. According to the latest market data compiled by European Bioplastics in cooperation with the Nova-Institute, global bioplastics production capacity is expected to increase from around 2.11 million tonnes in 2020 to approximately 2.87 million tonnes in 2025.

An increase in the number of enquiries for laboratory tasks according to the current standards has been observed to check whether raw materials or finished products comply with the requirements of the standards and, therefore, there is a need for obtaining eco-labels that ensure such results. As a result of this, a usual confusion has been observed on who is the body responsible for conducting tests and certifying products.

What is the role of recognized laboratories?

There is no specific legislation on bio-based materials, their uses and their applications. Nevertheless, there are different standards both national and international that aim to standardize these materials, in terms of renewable origin and/or end of compostable life.

These standards are not mandatory but set out the aspects and tests needed to determine the characteristics that materials and/or products must comply with. For example, the most used standards for testing biodegradability or compostability are:

Laboratories are responsible for conducting the tests needed and drawing up a final report with the results. Each certifying body has a list of recognized laboratories for companies that want to obtain a specific eco-label to conduct tests. AIMPLAS is recognized by the certifying body TÜV Austria for OK Compost INDUSTRIAL, OK Compost HOME, OK Biodegradable SOIL and SEEDLING labels through our tests.

What is the role of certifying bodies?

Certifying bodies aim to evaluate the complex information required by these standards and judge objectively and impartially the general characteristics of a material or product. This evaluation is conducted through certification systems. In general, it could be said that standards form the theory and certification systems turn this theory into practice.

Currently, different bodies promote product certification and provide those products complying with the requirements established by the standard with an emblem (a label or logo). Being certified involves being verified by an independent body:

The AIMPLAS Biodegradability and Compostability Laboratory is responsible for conducting the necessary studies so that companies can demonstrate the biodegradable and/or compostable nature of their products. Our reports are valid so that the certifying body TÜV Austria can give the eco-label of these products to the companies. You can find more information about these studies here.
