The UK government hosted two workshops to promote collaboration on the safe and sustainable development of advanced materials. These events brought together diverse stakeholders to share insights and shape relevant policies. Attendees highlighted the need for regulatory definitions, standards and test methods, and incentives to stimulate safe and sustainable development (SSbD) of advanced materials. In particular, there was a call for training small and medium enterprises (SMEs) on the SSbD concept and tools available for implementation. In addition, RIVM identified a need for improved integration of sustainability aspects like durability, reusability, and recyclability into SSbD approaches.
