Acronym: IS2H4C
Project number: 101138473
Funding Body: European Commission – Horizon Europe
Type of funding: Public

Duration: 49 months

Project description

Existing heavily industrialized areas are currently incapable of adopting large-scale industrial symbioses in terms of shared technology/infrastructure use, waste integration, energy and material utilization, as well as expanding through surrounding ecosystems in an inclusive manner for the society despite many of the EU’s key strategic priorities in sustainable regional development.

Within this context, IS2H4C proposes an ambitious and efficient innovation and action workplan to develop several solutions for the development of Hubs for Circularity (H4C) in diverse industrial areas of process industry surrounded by rural and/or urban settings in the Netherlands, Germany, Spain, and Turkey.

The workplan is shaped by development and deployment of most innovative sustainable technologies and infrastructure integration in four demo hubs and is supported by ground-breaking research on societal, governmental, and business innovation for H4C. IS2H4C scales up industrial areas to H4C via implementing systemic change and integrating the surrounding ecosystems to industrial areas.

The project implements a digital collaboration platform to manage the resource, infrastructure and information-sharing within H4C via embedding of decision-support modules in the platform. IS2H4C has the ambition of reducing the energy use, waste emissions, and carbon emissions by at least 10%, 20%, and 30% respectively.

IS2H4C will contribute to pave the path towards the development of H4C based on the circularity and resilience requirements of existing and future industrial zones and their surrounding ecosystems by prioritizing resource efficiency, maximizing use of renewable energy, prevention of waste, and promoting industrial/urban/rural symbiosis via reuse and recycling of unavoidable solid, liquid, and gas waste streams.

All in all, IS2H4C’s biggest ambition is to promote H4C as Europe’s future sustainable regional development models.
