Abstract
Rapid urbanization, population growth, and industrial expansion have made managing municipal solid waste a global challenge, particularly in India, the inefficiency of decentralized waste management systems has intensified the issue. About 40%â50% of Indiaâs solid waste is organic, much of it generated by cultural, social, and religious activities, contributing to pollution and health risks. A significant portion of this waste is flower waste, which is discarded after single-use in rituals and events, amounting to around 4.74 à 106 tons per day. Flower waste can be transformed into a range of valuable products such as incense, perfumes, dyes, compost, and bio-gas. Additionally, researchers have developed eco-friendly bio-sorbents from flower petals to effectively remove toxins from water. Our research is aimed to produce flower ash by drying flower waste in a muffle furnace at 650 °C for 3 hours. The EDAX data of the resulting flower ash had shown the occurrence of essential minerals as calcium, potassium, silicon, chlorine, and magnesium, with potassium being the predominant element. The SEM and XRD analyses of the flower ash demonstrated that it possesses a nanoparticle size and exists in a crystalline phase. This ash serves multiple purposes, including acting as a natural fertilizer, soil conditioner, and an effective agent in wastewater treatment for removing heavy metals due to its high surface area. Furthermore, flower ash is ideal for use in green cleaners and bio-construction materials. Thus effective management of floral waste can significantly reduce environmental pollution and play a key role in achieving approximately 60% of the United Nationsâ sustainable development goals.
