HolyGrail 2.0 in a nutshell
What exactly is HolyGrail 2.0? The project wants to use technology to make sorting - and thus recycling - more efficient. One of the techniques being used is Digital Watermarking. This places a code, which is invisible to the naked eye, on all sides of a product. When the product arrives on a sorting belt, a scanner detects the code and indicates what should be done for the recycling of the product. “In this way, you optimise sorting and avoid everything ending up in a single pile,” adds Jan Somers.
The role of GS1 standards
“Of course this Digital Watermarking cannot replace the familiar GTIN. The advantage of this is that you can also use a GTIN to see what type of recycling is required. The recycling information is linked to the GTIN. Actually the data provided by the GS1 standards make sorting and recycling machines smarter,” explains Jan Somers.
