On 20 March 2025 took place an internal training for PLANETS WP4 partners on Safe-and-Sustainable-by-Design (SSbD) and Tier 1 assessments, aligned with a Flame Retardant (FR) case study Workshop, in the headquarters of Steinbacher in Erpfendorf (Austria) in hybrid mode.

The aim of the training was to align the knowledge of project partners in the theory and purpose of SSbD Tier 1 assessment, its application as well as discuss about potential further adaptations needed in the SSbD workflow for the project’s case studies. On the basis of the jointly performed Tier 1 assessments onsite gap analyses were conducted and potential further adaptations prioritized for sector- or value chain position-specific requirements.

The session was prepared by Neeraj Shandilya and Thomas Hennequin (TNO), with the support of Joséphine Steck (CEA), Martin Himly, Sabine Hofer, Norbert Hofstätter (PLUS).

Training Materials

Building on the insights from this internal training, PLANETS has developed external training materials for conducting SSbD Tier 1 assessment following the PLANETS SSbD Workflow. These materials include:

• Workshop presentation slides
• Recording of the workshop [YouTube video]
• Questionnaire with guiding questions within the PLANETS SSbD workflow for conduct of the Tier 1 SSbD assessment

Insights from the PLANETS Flame Retardant Workshop (19-20.03.2025)

In the project PLANETS, the Flame Retardants Case Study focuses on the development of safer and more sustainable alternatives for flame retardants used in thermoplastics made from polystyrene and thermoset foams derived from polyurethane. 

To produce expanded polystyrene (EPS) materials, solid beads of polystyrene are used. These beads contain not only polystyrene but also additives required for the final product, such as dyes (coloring agents), nucleating agents, and flame retardants. During EPS production, the solid beads undergo a significant increase in volume due to the effect of a blowing agent and gentle heating. In contrast, polyurethane (PU) foam insulation does not require a heating process. PU foams form spontaneously when monomers, which already contain all necessary additives, are mixed together. This chemical process can be likened to baking a soufflé—only instead of eggs, sugar, and flour, a chemist “chef” uses various chemical ingredients. Just as a soufflé recipe must be carefully followed to achieve optimal results, the successful creation of polymeric foams relies on precise ingredient ratios, exact formulations and well-chosen process parameters. Alterations to an optimized recipe—for instance, changing the flame retardant—may adversely affect the final quality and performance of the foam. But don’t panic, unlike a soufflé, our insulating foams do not collapse.

On 5 March 2025, PLANETS consortium organised their first internal online training session on PLANETS’ Safe and Sustainable by Design (SSbD) workflow, with a primary focus on scoping. The training aimed to harmonize the consortium’s understanding of SSbD, particularly among innovators and industrial partners who are not directly involved in the project.

Training Highlights

The session was moderated by Martin Himly (PLUS), who leads the training work package within PLANETS. He introduced the session, outlining the objectives and structure of the training. Carla Caldeira (SYENSQO) then provided an insightful explanation of the policy background and fundamental principles of SSbD. Following this, Sabine Hofer and Norbert Hofstätter (PLUS) elaborated on the key actions involved in the scoping process. Joséphine Steck (CEA), the project coordinator, presented the PLANETS SSbD workflow in detail. To enhance practical understanding, a case study on plasticizers in seals (gaskets) was introduced by Martin Himly, serving as the foundation for the hands-on scoping exercise. Participants were divided into breakout groups to practice scoping actions, reinforcing the theoretical knowledge gained during the session.

Training Materials

Building on the insights from this internal training, PLANETS has developed external training materials to facilitate SSbD scoping following the PLANETS SSbD workflow. These materials include:

• Recording on policy background and SSbD basics [YouTube video]
• Recording on scoping actions [YouTube video]
• Recording introducing the PLANETS SSbD workflow, along with a practical exercise using the JRC gasket plasticiser case from the SSbD stakeholder engagement phase [YouTube video]
• Workshop presentation slides
• Case description detailing the JRC gasket plasticiser background
• Guiding questions and practical exercise worksheet listing potential solutions within the PLANETS SSbD workflow

A special thanks to Joséphine Steck (CEA), Carla Caldeira (SQO), Beatriz Alfaro (BNN), Norbert Hofstätter, Sabine Hofer, and Martin Himly (PLUS) for their valuable contributions to making this training a success!

On 5 December 2024, PLANETS was represented in Brussels by Simon Clavaguera of CEA at the 5th Stakeholder workshop on “Safe and sustainable by design”, held by the Joint Research Center.  
 
PLANETS partners Wouter Fransman of TNO and Wendel Wohlleben of BASF were also present, while other partners attended online.  

The main focus of the workshop was on the outcomes of the second reporting period of the SSbD framework, the lessons learnt and the ways forward before the revision of the framework in 2025.
