The granite production chain is high energy and water intensive with low resource efficiency. This paperfocus on characterizing the potential for environmental improvement of the granite production chain bypromoting the optimization of sawing technology, the implementation of rainwater harvesting (RWH)and the material recovery of wasted granite (sludge).The environmental performance of multi-blade gangsaw (MBGS) and diamond multi-wire saw(DMWS) technologies is compared by mean of life cycle assessment. Results demonstrate that DMWStechnology contribute 30% of water savings, 40% of energy savings and 80% of material savings per squaremeter of polished granite tiles (60 x 40 x 2 cm) production. These resource savings contribute together toreduce the product’s environmental footprint by 35% to 80%.The potential for RWH is analyzed using Plugrisost simulation software based on system dynamics.RWH depends on the relationship between rainfall, catchment surface and tank size according to theindustrial process’s water demand. The results demonstrate major potential to satisfy over 50% of thesystems daily water requirements using rainwater stored in rainwater tanks of varying capacity. RWH is asustainable strategy for industrial water cycle management.A comprehensive review of literature reveals a range of technically feasible alternatives to promotematerial recovery of granite sludge. The ceramic industry is one promising industrial endpoint withwhich to avoid waste landfilling and contribute to mineral, energy and water savings. This by-productsynergy could also serve as starting point for springboarding exchanges with other industrial agents,becoming a global extension of resource efficiency.
