Europe has entered in the transition period from a linear to a circular economy. The European Commission adopted an ambitious Circular Economy Package with clear targets for reduction of waste and recycling. In a circular economy, reuse, repair and recycling become the norm and waste is a thing of the past. Finke is providing you with tailor-made masterbatch solutions to put this target into reality.
The key to recycling post-consumer waste is sorting. Common packaging polymers like PP, HDPE, PS, PET need to be separated to re-enter the material stream. Only pure material streams can ensure good properties and high quality of the recycling material. Near infrared spectroscopy (NIR) has proven very successful in the sorting process and has become standard technology in recycling plants. However, sorting plastic material coloured with carbon black by NIR technology can be challenging. The carbon absorbs a good part of the infrared radiation, which renders the polymer virtually “invisible” to the NIR-sorting machine and thus indistinguishable. As a result, separating different polymers like PP, HDPE, PS and PET into the correct material streams becomes difficult.
To ensure the recyclability of black plastic products, we at Finke have come up with a range of FIBAPLAST NIR detectable Black masterbatches for standard packaging polymers like HDPE, PP, PS and PET. With this development we are able to close the gap for black coloured plastic materials in circular economy.
By using a carbon back-free pigment formulation for our FIBAPLAST NIR detectable Black masterbatches we ensure that black products become fully detectable on NIR-sorting machines. Thus, black HDPE- , PP-, PS- and PET- bottles, trays or caps can be separated easily into the correct recycling material streams using standard technology.
After successful trials conducted together with leading sorting machine manufacturers, COTREP (Comité Technique pour la Recyclage des Emballages Plastiques) has certified our FIBAPLAST NIR detectable Black masterbatches for rigid PE and PP packagings in October 2020. COTREP has confirmed that products colored with the new FIBAPLAST NIR detectable Black masterbatches can be sorted by NIR technology in standard sorting facilities for post-consumer plastic packaging. Up to a concentration of 5 % masterbatch in the product, the packaging material is reliably detected and can be fed into the respective recycling stream.
At our technical center we can tailor a FIBAPLAST NIR detectable Black masterbatch exactly to your application within a very short time. With our expertise and comprehensive technical support we enable rapid marketability of your sustainable and environmentally compatible products. We remain at your disposal for more information.
