Reusable drug delivery devices are gaining renewed attention as the industry responds to rising sustainability pressures, the rapid growth of GLP-1 therapies, and increasingly complex formulations.

In this video, Steve Gowers, TTP's head of Drug Delivery, explores the real-world trade-offs behind reusability, from carbon breakeven points and device longevity to patient behaviour, adherence, and system-level design challenges.

He outlines three practical tools for navigating these complexities: learning from real-world datasets, applying systems thinking through modelling, and incorporating behavioural design principles to ensure reusable devices deliver meaningful environmental benefit in practice, not just in theory.
