Why recyclate quality is so difficult to compare
For virgin material, material types, specifications and technical data sheets are usually well established. With recyclates, the situation is more complex: different input streams, collection systems, sorting qualities and processing methods can lead to very different property profiles — even within the same polymer type.
Technical data sheets are helpful, but they often only provide a limited view of these differences. Testing scope, key values and presentation can vary from supplier to supplier. As a result, procurement, quality assurance and application teams face a high level of interpretation effort — especially when materials need to be approved, compared or documented for customers.
The problem is often not the recyclate itself.
The problem is the lack of a common basis for quality assessment.
The practical consequences:
▪️Offers are difficult to compare.
▪️Material approvals become time-consuming individual projects.
▪️Good recyclate quality cannot always be documented neutrally.
▪️Sourcing decisions remain uncertain.
▪️Brands and manufacturers need reliable proof for the use of recyclates.
