Materials for Sustainable Building and Infrastructure - Recycled Aggregates

Materials for Sustainable Building and Infrastructure - Recycled Aggregates (MEISAR) is the research project financed by the Autonomous Region of Sardinia (POR Sardegna FESR 2014/2020 - ASSE PRIORITARIO I - "RICERCA SCIENTIFICA, SVILUPPO TECNOLOGICO E INNOVAZIONE" Azione 1.1.4 Sostegno alle attività collaborative di R&S per lo sviluppo di nuove tecnologie sostenibili, di nuovi prodotti e servizi. REALIZZAZIONE DI AZIONI CLUSTER "TOP-DOWN") that wants to develop an eco-sustainable chain of concrete constructions by enhancing recycled aggregates.

Ecosustainable supply chain

A supply chain of elements made of recycled concrete could drastically reduce the exploitation of the land, caused by the extraction of natural aggregates from the quarries, and the construction and demolition debris to be landfilled, with obvious environmental and economic advantages.

Concrete producers could exploit the waste materials they produce as recycled aggregates for the production of new mixtures.
