The markers we use are completely harmless to health in the intended quantities and are FDA-approved for food contact. Furthermore, our markers are not nanoparticles. This means that they are not respirable.

Material tests with industry partners confirm that the mechanical and optical properties of the product remain unaffected.

In mechanical recycling, the marker remains in the material and can be reused in the next product life cycle.

For plastic products, the marker can be added during the production process. Alternatively, integration via paints and varnishes, such as printing, is also possible.

Our fluorescent markers are inorganic.

No. Sort4Circle® technology is a new, innovative and technology-neutral sorting process. A variety of established detection technologies such as NIR and MIR as well as optional marker technology (tracer-based sorting) can be used.

Markers depends on the characteristics of the material to be marked. A few ppm is sufficient for light-colored materials, while up to 200 ppm is required for dark materials.

The number of fractions that can be sorted depends heavily on the number of detection technologies used. If optical detection technologies such as NIR and MIR detection markers are used in addition to optical detection technologies, well over 50 fractions can be differentiated.

All detection methods used require only a few milliseconds for an evaluation. The limiting factor is the system. With an S4C sorting line, 5 objects per second can be sorted with an average object size (approx. 10 cm). To increase throughput, sorting lines can be operated in parallel. 

Sort4Circle® is more economical than conventional cascade sorting from six fractions upwards. The process also offers maximum efficiency thanks to its openness to technology and a purity of the sorted fractions of over 99%, which maximizes the yield.

Internet access is required for registration and identification, as the object IDs are stored centrally in a database.

Only the particle pattern and the object ID are stored in the central database. The object ID can be used in your own database to store all the required data.

Since the fingerprints are based on the random particle distribution, several trillion unique and uncopyable fingerprints can be generated.

With a corresponding wireless detector, fingerprints can be read out via the smartphone.

The fingerprint is invisible and has no influence on the optical properties of the object.

The fingerprint requires a circular surface with a diameter of just 15 mm.

For light-colored or non-colored objects, just a few ppm are sufficient. Dark objects, such as colored plastics with carbon black, require a concentration of up to 200 ppm.

No, our BRANDPROOF detectors do not require Internet access. All relevant parameters are determined and set by us before delivery.

For light-colored or non-colored objects, just a few ppm are sufficient. Dark objects (e.g. colored plastics with carbon black) require a concentration of up to 200ppm.
