The concept was initially applied similar to the process of extracting silica from ash. Extracted Residue Powder (ERP) thus obtained by systematic processing of fish residue contained many noble elements like Silica, Calcium, Carbon, Magnesium, Sodium etc. which were scrutinized later by FESEM compositional analysis. The ERP was used as a particulate in the epoxy based composite where it shows appreciable compatibility, bonding characteristics and enhancement in mechanical properties. The extracted residue powder resulted in good thermal and decomposition characteristics as seen in TGA analysis at 320 and 720 degree centigrade.

Introduction Various elements and compounds like Silica, Calcium Carbonate and Magnesium etc. were studied as a particulate having good compatibility with epoxy resin matrix (Paluvai et al., 2014). Efforts were made to extract the elements from livestock waste for the cost effective development of composite with high strength to weight ratio. With the time it was diagnosed using literature survey that the fish residue may contains many useful elements if chemically treated and processed. Jin and Park (2009) described the thermal stability of nano sized calcium carbonate (CaCO3) in modified tri functional epoxy resin. The results showed high cross linking density and decreased coefficient of thermal expansion at the region of high contamination of particles. Mittal (1997) performed the laboratory experiment on rice husk ash to get silica from ash. Rice husk ash contains 90-98% silica. He then performed the following two reactions under controlled condition to get silica from ash.
