The quality-control process in plastic recycling is underwhelming, the current technique can only tell the material properties of a sample between 1-20 mg or smaller. This is far below the industrial need.

Our team is developing a radically different and innovative Differential Scanning Calorimetry (DSC) technique, upscaling the sample size to 500 grams. This increase in measurement certainty increases the commercial value of recycled plastics in most cases by at least 25%. Based on our technique, analysis of composites or thin-film polymers is also possible. 

The Veridis Instruments Bulk-DSC is the first DSC built with the requirements for recycling in mind. This involves minimizing the sample preparation, optimizing sample size and making the interpretation and evaluation of the results as easy and intuitive as possible. The Bulk-DSC specifications are displayed below.
