Circular economy creates new products through collaboration among all actors of the QUADRUPLE HELIX model, aiming for ecological stability and the economic sustainability of regional development, with a focus on socially equitable working and living environments in the QUINTUPLE HELIX innovation model.

The QUADRUPLE HELIX innovation model consists of four key stakeholders in the innovation ecosystem: academia and education, government, industry, and society. Civil society plays a critical role in integrating innovative activities into systemic solutions for regional development.
The QUINTUPLE HELIX innovation model promotes the creation of a high-quality, competitive, and socially responsible business environment through close collaboration with regional governments, academia, applied research, and an informed public in a knowledge-driven economy.
The Innovative Quintuple Helix Model - Global Warming as a Challenge and Driver of Innovation
The Triple Helix innovation model focuses on the relationships between universities and industry.
The Quadruple Helix model expands the Triple Helix framework by adding the "media and cultural public" and "civil society" as the fourth pillar.
The Quintuple Helix innovation model, or the fivefold spiral, is even broader and more complex, as it contextualizes the Quadruple Helix while adding the "natural environment of society" as the fifth element and perspective.
The Triple Helix model explicitly acknowledges the importance of higher education in driving innovation. From one interpretation, it could be argued that the Triple Helix model emphasizes the production and innovation of knowledge in the economy, aligning it with the concept of a knowledge economy. The Quadruple Helix model, on the other hand, supports the perspective of a knowledge society and knowledge democracy for the production and innovation of knowledge. To fully understand the Quadruple Helix, sustainable development in the knowledge economy requires co-evolution with a knowledge society.
The Quintuple Helix model emphasizes the essential socio-ecological transition of society and the economy in the 21st century; thus, it is ecologically sensitive. Within the Quintuple Helix innovation model, the natural environment of society and the economy is recognized as a driving force behind the production and innovation of knowledge, thus defining opportunities for the knowledge economy.
In 2009, the European Commission identified the socio-ecological transition as the main challenge for future development planning. The Quintuple Helix model fosters the creation of mutually beneficial scenarios between ecology, knowledge, and innovation, generating synergies among the economy, society, and democracy.
Global warming represents an area of ecological concern where the Quintuple Helix innovation model can be applied with significant potential.
INNOVATIVE APPROACH
The Quintuple Helix innovation model consists of the interaction of five subsystems (helixes):
EDUCATION - BUSINESS - PUBLIC ADMINISTRATION AND LOCAL GOVERNMENT - PUBLIC - ENVIRONMENT in a knowledge-based economy.
Social Ecology and Environmental Protection for Innovation, Sustainable Development, and Economic Growth
The framework of the Quintuple Helix can be described through knowledge models that it expands, and through the five subsystems (helixes) it incorporates. In this fivefold spiral model, knowledge and know-how are created, transformed, and circulated as inputs and outputs in a way that impacts the natural environment.
Social-ecological interactions through the Quadruple and Quintuple Helix models can be leveraged to define opportunities for a knowledge society and knowledge economy, such as innovations addressing sustainable development, including climate change.
Investments in education play a pivotal role in driving sustainable development, especially when integrated within the framework of the Quintuple Helix model. By fostering innovation, collaboration, and knowledge transfer among education, business, public administration, the public, and the environment, such investments help create long-term, holistic solutions that address economic, social, and ecological challenges. These investments not only enhance human capital but also contribute to the development of a knowledge-based economy, driving sustainable growth, technological advancements, and social well-being.
In this context, education empowers individuals and communities, fostering the competencies needed for sustainable practices and climate resilience. As a result, the Quintuple Helix model underscores the importance of education as a foundational pillar for the sustainable transformation of society and economy.
