The article considers the possibility of using wastepaper sludge ash (WSA) as a soil reinforcement material for construction layers road wear. Loamy sand, sandy loam, silty clay were chosen soils strengthening. maximum density skeleton at optimum humidity was established by method Proctor. Wastepaper and Portland cement grade 400 used separately Six compositions strengthened each type investiga...

Stickies continue to represent the most challenging contaminant to remove from recycled secondary fiber. Current projections suggest that pressure sensitive adhesive (PSA) markets will continue to grow rapidly, increasing the concentration of these contaminants in common office-pack wastepaper. PSA’s reformulated to exhibit higher removal efficiencies within standard secondary fiber processing ...

The utilization of less expensive and more effective adsorbents derived from a variety basic materials has been investigated. research aimed to investigate the feasibility employing waste paper as adsorbent remove cresol red (CR) dye wastewater through adsorption mechanism. Langmuir, Jovanovic, Freundlich model were observed for isotherms models, while pseudo-first-order pseudo-second-order exa...
