The increasing demand for sustainable water remediation solutions has brought to light the potential of agricultural waste as a resource for improving water quality. sugarcane bagasse, an abundant byproduct of sugarcane processing, can be transformed into biochar through pyrolysis, addressing both agricultural waste management and water purification challenges. sugarcane bagasse biochar (sbb) has demonstrated promise as an effective material for water treatment due to its high porosity, large surface area, and functionalized groups, which make it highly suitable for adsorbing a wide range of impurities, including calcium and magnesium ions responsible for water hardness. water hardness, primarily caused by high concentrations of calcium and magnesium ions, is a prevalent issue in regions like vatika, jaipur, where groundwater sources are particularly affected by geological factors. hard water can cause several detrimental effects on both human health and the environment. the long-term consumption of hard water has been associated with health problems such as kidney stones and cardiovascular issues due to the excess calcium and magnesium. additionally, hard water leads to scaling in pipes and appliances, reducing their efficiency and lifespan, and increasing maintenance costs. traditional water softening techniques often involve expensive and environmentally taxing chemical treatments. in contrast, sbb presents an eco-friendly, cost-effective alternative that can effectively remove hardness-causing ions, offering a sustainable solution to long-term water quality challenges. this study explores the application of sbb for hardness removal in vatika’s water, where such contamination is a significant concern. the production of sbb is aligned with the principles of a circular economy. by converting agricultural waste into a valuable resource, sbb contributes to waste management and sustainability goals while minimizing environmental impact. this ecofriendly approach supports sustainable development by offering a greener alternative to traditional chemical water treatment methods. in this study, sbb was prepared through optimized pyrolysis conditions to maximize its ion-exchange capacity for hardness removal. batch adsorption experiments were conducted using water samples from vatika, demonstrating that sbb effectively adsorbed calcium and magnesium ions, resulting in significant reductions in water hardness levels. these reductions met the permissible limits set by water quality standards, highlighting the biochar’s potential as a reliable and long-term solution. furthermore, sbb’s performance remained stable over multiple regeneration cycles, proving its reusability and sustainability. beyond its technical properties, the adoption of sbb for water treatment in vatika also addresses socio-economic challenges. the use of locally available sugarcane bagasse not only offers an affordable and accessible solution to rural communities but also promotes the development of local industries and job creation. by involving the community in the production and application of biochar, this approach fosters a sense of environmental responsibility and community engagement. it can also contribute to improving public health by ensuring access to cleaner, safer water. in conclusion, this study highlights the transformative potential of sugarcane bagasse biochar as an eco-friendly, sustainable solution for water hardness removal in vatika, jaipur. by leveraging the unique properties of sbb, we can address local water quality challenges while promoting waste management, environmental sustainability, and socio-economic development. the integration of sbb into existing water treatment frameworks not only enhances water quality but also contributes to a circular economy, turning agricultural waste into a valuable resource. the findings suggest that sbb could redefine water treatment practices, offering a greener, more sustainable alternative to traditional methods, with the potential to positively impact water management on a broader scale.
