This document discusses building an innovation ecosystem around ocean sustainability in Peniche, Portugal. It proposes creating an Ocean Tech Hub to empower coastal communities and be a flagship for ocean innovation and circular economy. The hub would leverage emerging technologies like AI, robotics, and blockchain to pursue opportunities in recycling ocean waste, recovering ocean litter, and sustainable entrepreneurship. It outlines initial partnerships and pilot projects, including using drones to map ocean litter and extend an existing fishing data service to collect plastic waste. The goal is to increase competitiveness of small fishing businesses while greening operations and benefitting the local ecosystem through access to new markets, capabilities, and serendipitous innovation through collaboration.
