• CASAN launched an initiative on October 26, 2026, to reuse sludge from its Barra Velha water treatment plant in brick production.
• The initial phase will send 600 metric tons of sludge to ceramics producers in Tijucas and Canelinha.
• A new removal contract cuts costs 11% to R$ 520.15 per metric ton from R$ 587.39 for removal and landfill disposal.
• Shorter transport distances will reduce carbon emissions, while sludge reuse will curb clay extraction for brickmaking.
• The circular-economy initiative could expand to other water treatment plants.
