Matter by Design. How can circular economy play a role in building green efficient and sustainable through innovative use of Mediterranean materials.

Abstract

The shift towards a circular economy, moving away from the traditional linear "take, make, dispose" model, has gained momentum due to its potential for fostering green, efficient, and sustainable practices. Particularly in the Mediterranean region, characterized by its rich history, diverse ecosystems, and unique resources, there is a promising opportunity to implement these principles in construction and design methods.The Mediterranean abounds in resources from cork to ceramics, offering a diverse set of raw materials that can be sustainably harnessed. The challenge is to reimagine how these materials are sourced, processed, utilized, and eventually repurposed or recycled. Leveraging technology innovation, a product of the Fourth Industrial Revolution, may revitalize these traditional Mediterranean materials.One significant aspect of building a circular economy in the Mediterranean is the integration of traditional craftsmanship and techniques. Local artisans, who have been working with materials like cork and clay for generations, can blend these time-honoured methods with modern technology to create innovative products.This paper describes a project aimed at activating collective memory and cultural identity as a reference for design activity, fostering critical thinking to drive urban communities towards including Mediterranean materials in green building development. The project involves the conception and development of a modular-based product that incorporates both active and passive solar functions with aesthetic characteristics. The goal was to create a solar experimental product for cladding building surfaces (vertical and non-vertical façades), combining parts with passive solar characteristics—including solar protection elements, solar thermal energy storage, ventilated walls, and Trombe wall effects—with active solar parts such as solar thermal collectors and photovoltaic systems.The modular-based solar cladding product successfully improved energy efficiency and contributed to reducing the building's overall energy consumption. The incorporation of locally-sourced Mediterranean materials, such as cork, not only enhanced the sustainability of the product but also promoted the use of indigenous resources.In conclusion, the circular economy, when applied in conjunction with the innovative use of Mediterranean materials, can lead to a greener, more efficient, and sustainable future. By valuing and reimagining traditional craftsmanship, harnessing the potential of diverse resources, and embracing cutting-edge recycling technologies, the Mediterranean region can become a showcase for circular economy success, demonstrating how environmental stewardship and economic prosperity can go hand in hand.
