Paper Mill Lime Sludge

Description

1. Product Overview

Kraft Pulp Recovery Residue is a secondary industrial material generated during the chemical recovery process in kraft pulp mills. This residue contains valuable inorganic and carbon-rich components that can be repurposed for multiple industrial applications, including construction materials, soil amendments, and energy recovery systems. By converting a by-product of pulp manufacturing into a usable raw material, it offers significant cost efficiencies and supports circular industrial supply chains. Strategically, Kraft Pulp Recovery Residue is increasingly valued by manufacturers seeking sustainable, cost-effective alternatives to virgin mineral inputs while improving resource utilization.
