Concrete findings to better understand, measure and promote reuse.

Reuse regulations: between French ambitions and the European framework, where do we really stand?

Reuse regulations: between French ambitions and the European framework, where do we really stand?

France has set ambitious reuse targets through the AGEC law, while the European Union is developing its own policy framework. Yet the regulatory landscape is still perceived as fragmented, unclear, and insufficient to enable reuse stakeholders to grow under competitive and sustainable conditions.

So what is the current reality of the regulatory framework in practice? What are the key priorities and areas for improvement? Let’s take stock of the current situation and explore the regulatory opportunities ahead.

How to fight obsolescence through reuse

How to fight obsolescence through reuse

While many goods and pieces of equipment are discarded or dismantled each year without capturing their potential value, reuse is emerging as a strategic solution to maintain their functionality and extend their lifespan.
From packaging to WEEE (waste electrical and electronic equipment), including industrial machinery, these products often remain functional despite their “obsolescence.” Repair and spare parts therefore become key strategies for restoring value to obsolete items and keeping equipment and products in use.
Waste reduction, extended product lifespans, greater independence from manufacturers, and savings in time and money… this Masterclass will explore the key challenges of combating obsolescence through reuse across various sectors.

LCA or PCDS (Product Circular Data Sheet): which tool should you choose to facilitate the reuse of your products?

To scale up reuse practices, companies can start from several entry points.
Life Cycle Assessment (LCA) makes it possible to analyze impacts throughout the entire life cycle.
The Product Circularity Data Sheet (PCDS), supported by the ISO 59040 standard, provides an operational tool focused on product characteristics.
It helps identify reuse levers, facilitates their implementation, and anticipates the necessary adaptations from the design phase onward.

This masterclass offers an opportunity to understand the PCDS, its benefits, and its complementarity with LCA, through practical case studies.

How can the circular economy become a broader political and societal project?

How can the circular economy become a broader political and societal project?

At a time when the world is once again becoming a stage for imperial power struggles, France must more than ever protect and intelligently support its future. The circular economy—a unique driver of economic and industrial sovereignty, local dynamism and social cohesion, and a proactive ecological transition—must be elevated to the rank of absolute priority in this context. What strategy should we adopt to turn this into a truly comprehensive political and societal project?

How can we raise awareness of the importance of reuse and the circular economy among a wider audience?

The adhesive label, a key driver of reuse: combining performance, marketing, and circularity

The adhesive label, a key driver of reuse: combining performance, marketing, and circularity

If packaging is redesigned for reuse, labels must be too. As both an information medium and a marketing tool, labels play a decisive role in the user experience and in the efficiency of reuse cycles.

This masterclass will explore reuse in its various forms, including:

 Consumer reuse of packaging
 Reuse of glass containers in industrial systems
 Reuse of glass containers in the food service sector (HoReCa)
 Reuse of industrial plastic containers

We will share our vision of permanent identification to track the life cycle of containers, as well as “non-permanent” identification for variable elements.

We will also present our perspective on adhesive labels as facilitators of reuse, washing processes and product identification.

Traceability: overcoming barriers to implementation

Traceability: overcoming barriers to implementation

Traceability is a key performance lever for the reuse of packaging. It is also a prerequisite of the EPR scheme for industrial and commercial packaging. But how can traceability be implemented easily and integrated into day-to-day operations without adding complexity? Which traceability solutions deliver which benefits, and at what cost? To answer these questions, this session will share practical feedback and provide an overview of existing solutions.
