"extracellular polymeric substances (EPS) recovered from anaerobic granular wastewater sludge cost-effective, sustainable... enhances waterproofing (65%), oil and grease resistance... multi-layered paper's surface microstructure smoother, less porous... EPS rich sludge, widely used removing pollutants from wastewater, potential alternatives to synthetic polymers in agricultural, medical, and construction biomaterials, having polysaccharides, proteins, and humic-acids... best samples from paper-industry sludge"
