Siegwerk is cooperating with CEFLEX, a collaborative European consortium of companies and associations representing the entire value chain of flexible packaging, to develop advanced flexible packaging solutions for a circular economy.
Siegwerk is a committed member of the initiative, contributing its extensive ink expertise to enhance performance and recyclability of flexible packaging to help realise the full potential for a sustainable future.
The CEFLEX initiative unites almost 100 companies and associations from the entire value chain of flexible packaging – from manufacturers of packaging films and processors (including ink providers), to brand owners, retailers and specialised companies for recycling. ‘CEFLEX is the most significant and solution-oriented industrial initiative for flexible packaging,’ explained Jörg-Peter Langhammer, head of global PSR and Sustainability at Siegwerk. ‘It offers a perfect platform to network and exchange with experts from other areas and to cooperatively shape the future by redesign and innovation, along with the parallel development of a strong infrastructure to collect, sort and recycle flexible packaging. I am firmly convinced that together we can make a real difference.’
Flexible packaging represents an application area that provides customised product protection at minimum total cost and with the lowest environmental impact. CEFLEX and its stakeholders are fully committed to the goal of 100 percent collection and recycling of all plastic packaging. Working together, the initiative’s underlying goal is to prepare a comprehensive sustainability and circular economy roadmap for flexible packaging by 2020.
Next to design guidelines for flexible packaging in a circular economy, this roadmap shall include activity plans for an increased resource efficiency as well as measures for the optimised collection of flexible packaging waste and recovery of recyclables. By 2025, CEFLEX wants to establish a collection, sorting and reprocessing infrastructure based on the most cost-effective and environmentally friendly processes, concretely developed for post-consumer flexible packaging across Europe. Alongside CEFLEX, Siegwerk fully supports the Global Commitment and Common Vision issued by the Ellen MacArthur Foundation (EMF) on a New Plastics Economy, envisaging a future where plastic, including flexible plastic packaging, never becomes waste and is in line with a circular economy.
Siegwerk’s contribution applies to printing inks and varnishes and their essential role in the future of flexible packaging. Today, the company’s experts are participating in three of the seven overall workstreams that were established to achieve CEFLEX’s defined goals. These include:
1. Design Guidelines for a Circular Economy.
2. Sustainable End Markets.
3. Facilitating Technologies.
Through its work, Siegwerk contributes to the design guidelines for flexible packaging in a circular economy and the influence of inks and printed layers on the automatic sortability of flexible packaging waste and on recyclates derived from mechanical recycling including extrusion. Together with all other stakeholders, Siegwerk takes the discussion further and investigates the removal from inks and printed layers during the recycling process (deinking) to improve the quality of the recyclates. Ultimately, Siegwerk is engaged in investigations on ink influence within advanced recycling technologies like chemical recycling, where polymers are extracted from pre-sorted post-consumer waste streams. Apart from mechanical recycling many of these advanced recycling technologies haven’t been used on a large scale yet and thus might be promising options for the future.
