Eco-Inject is a Cambridge based medical device company reinventing the autoinjector from first principles. Founded by medical device development veteran John Palmer-Felgate, the company has eliminated complexity while achieving significant carbon reduction at cost parity. The platform maintains full compatibility with existing pre-filled syringes (1 & 2.25 mL). Pharma partners can adopt sustainable drug delivery without changes to fill-finish processes, supply chains, or patient training. Cost parity meets carbon reduction. Total reinvention meets zero disruption.
