In a groundbreaking development that could revolutionize the construction and energy sectors, researchers have successfully synthesized nano dicalcium phosphate dihydrate (DCPD) from marine shell waste. This innovative approach, led by Md. Kawcher Alam of the Glass Research Division at the Institute of Glass & Ceramic Research and Testing, Bangladesh Council of Scientific and Industrial Research (BCSIR), and the Department of Applied Chemistry and Chemical Engineering at Noakhali Science and Technology University, offers a sustainable and cost-effective solution to a longstanding industrial challenge.
The study, published in ‘Results in Materials’, utilized calcium-enriched marine sources such as Turritella, Cardium, and Conch shells to produce DCPD. This method not only addresses the growing demand for raw materials but also provides a viable solution for managing marine waste. “The use of these biogenic sources for DCPD production is not just environmentally friendly but also economically beneficial,” Alam explains. “It turns waste into a valuable resource, which is a win-win for both the environment and the industry.”
The process involves reacting orthophosphoric acid with powdered shell substances, resulting in DCPD with a sheet-like or irregular shape. The synthesized materials were rigorously analyzed using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and Fourier-transform infrared spectroscopy (FT-IR). The results were striking. SEM images revealed a plate-like structure with homogeneity in size and shape, while EDX confirmed the presence of essential elements like calcium, phosphorus, and oxygen. The crystallite size, determined using different XRD models, ranged from 11.23 to 35.55 nanometers, indicating high purity and uniformity.
The implications of this research are vast, particularly for the energy sector. DCPD is a crucial component in various industrial applications, including cement production and phosphate fertilizers. By providing an alternative source for DCPD, this study paves the way for more sustainable and efficient manufacturing processes. “This research opens up new possibilities for the energy sector,” Alam notes. “It allows us to produce essential materials without relying on finite resources, thereby reducing our environmental footprint.”
The findings also highlight the potential for further advancements in material science. The synthesis of nano DCPD from marine waste demonstrates the feasibility of creating high-quality materials from readily available, renewable sources. This could inspire similar innovations in other sectors, leading to a more circular economy where waste is minimized, and resources are optimized.
The research not only underscores the importance of sustainable practices but also showcases the potential of marine waste as a valuable resource. As industries continue to seek eco-friendly solutions, this study provides a blueprint for turning waste into wealth. The commercial impacts are significant, offering a cost-effective and sustainable alternative to traditional methods. With the growing demand for green technologies, this research could shape future developments in the field, driving innovation and sustainability in the construction and energy sectors.
