Eutrophication, a major environmental and economic issue, stems from the increased nutrient levels in water bodies, notably phosphorus, demands focused attention. On other hand, investigating phosphate recovery options receive immediate attention, as sources are limited. Many studies have been dedicated to development of tailored biochars effective agents for adsorption aqueous environments. This review explores multifaceted advantages Ca/Mg-rich biochars, with primary focus on their exceptional uptake capabilities. Beyond remarkable sequestration potential, these offer diverse benefits, including non-renewable recovery, soil enhancement, resource utilization, waste management, conversion. Nevertheless, complex preparation methods, reliance expensive metallic reagents, energy-intensive equipment pose significant limitations mass production composites. In response challenges, this critically evaluates latest Mg/Ca-biochar synthesis strategies, highlighting need sustainable materials fabrication methods enhance viability. Furthermore, potential spent Ca/Mg-biochar hybrids, enriched substantial loadings, is examined, offering insights into utilization safe slow-release fertilizers or recycling through practical methods. The also delves easy, cost-effective, environmentally friendly regeneration reuse which can be implemented Ca/Mg biochars. Finally, article summarizes real-time applications, limitations, identifies crucial knowledge gaps, outlines future directions, advance use Ca/Mg-modified various applications.

Phosphorus (P) is a crucial factor influencing both plant growth and the enrichment of aquatic environment. Agriculture primary sector economy where demand for phosphorus highest. Due to depletion P, more attention being paid possibility recovering reusing P through idea circular (CE). The main objective this study was compare raw eggshells (R-ESs) calcined (C-ESs) removal from wastewater assess possible use agro-waste materials according CE requirements in non-flow conditions. A synthetic indicator, zeroed unitarization method, calculated evaluate critical aspects CE. sorption R-ESs C-ESs equaled 0.90 1.66 mgP-PO4/g an initial concentration 17.3 mgP-PO4/L. were characterized by almost two times higher reduction rate than R-ESs. indicator 0.89 0.72 C-ESs, respectively. This means that are sustainable C-ESs. Although potentially have significant environmental impact, it worth considering method elimination beneficial ecological perspective.
