        abstract = {Heavy metal contamination in wastewater, 
particularly copper, threatens ecosystems and human 
health, necessitating sustainable and biosafe treatment 
solutions. This study evaluates low-cost, eco-friendly 
adsorbents—chalk powder, eggshells, and coconut 
husk—for copper removal, emphasizing biosafety by 
minimizing secondary pollution and utilizing waste 
materials. Experiments under alkaline conditions 
revealed that chalk powder significantly reduced 
copper concentrations, demonstrating its potential as a 
safer alternative to conventional methods like 
activated carbon. Partial results indicate that these 
adsorbents effectively lower copper levels while 
avoiding toxic byproducts, aligning with biosafety and 
circular economy principles. The findings highlight the 
promise of such materials for small-scale industrial 
applications, offering a balance between efficacy, 
affordability, and environmental safety.},
