As one of the world's leading manufacturers of colour solutions for packaging printing, Siegwerk focuses on continuously improving the environmental footprint of its products and actively driving the transition to a circular packaging industry.<\/em><\/p>\n

But what contribution can printing inks and coatings make to creating a circular economy? Firstly, their technical functional properties enable the realisation of all three principles of the circular economy: Reduce, reuse and recycle packaging. <\/strong>Alina Marm is Head of the Circular Economy Hub at Siegwerk<\/strong> responsible for driving the company's transition towards a circular economy:<\/p>\n

\u201eWhen switching from plastic to paper, but also from multi-plastic to mono plastic, printing inks and coatings help to maintain the necessary functionality of the packaging. Special sealing lacquers for processing the packaging and barrier lacquers to protect the packaged goods are key here.\u201c Alina Marm<\/strong>, Head of Circular Economy Hub at Siegwerk.<\/p><\/blockquote>\n

However, successful recycling is also the topic of deinking packaging<\/strong> The removal of paints and varnishes before the recycling process plays a key role in this. There is currently no established deinking infrastructure in Germany. This is a challenge for the entire industry. The Siegburg-based printing ink manufacturer is therefore already working with partners along the entire value chain on pilot projects for selected material flows and recycling technologies. .<\/p>

Siegwerk paints are suitable for solvent-based recycling<\/h2>\n

Together with the Plastics recycling company APK<\/strong> this spring, for example, Siegwerk tested a series of LDPE film samples printed with the company's inks. The aim of the series of tests was to clarify whether the Siegwerk inks could be used with a solvent-based recycling process<\/strong> such as APK's Newcycling\u00ae technology can be removed from the polymer matrix.<\/p>\n

\u201eWe consider the entire packaging life cycle, from design and production through to recycling. We are therefore delighted that Siegwerk's printing inks are clearly suitable for solvent-based recycling and that a much-discussed challenge for the recycling of flexible packaging has been overcome.\u201c Ralf Leineweber<\/strong>, Head of Global Technology Development at Siegwerk.<\/p><\/blockquote>\n

In addition, Siegwerk also uses its expertise for deinking in today's established mechanical recycling processes in order to significantly improve recyclate quality.<\/p>
