Power Plant Lime Residue

Description

1. Product Overview

Power Plant Lime Residue is a calcium-rich industrial byproduct generated from flue gas desulfurization (FGD) systems and other lime-based emission control processes in thermal power plants. It is primarily utilized in cement manufacturing, construction materials, soil stabilization, and environmental remediation applications.

With its high calcium oxide (CaO) and calcium sulfate (CaSO₄) content, this material offers a cost-effective alternative to virgin lime and gypsum inputs. Strategically, it enables industrial operators to reduce raw material costs while supporting circular economy initiatives and regulatory compliance in waste valorization.
