Abstract— Coir pith is a byproduct of coir industry. It is dumped as an agricultural waste for a long period of time. Usually it is disposed by burning which may release lot of carbon into atmosphere causing air pollution. Coir waste has a high lignin and cellulose content. its carbon nitrogen ratio is around 100:1. Because of the high lignin content Left to itself, coir waste takes decades to decompose.Thus it is leached out during course of time due to rain in to water resources causing water pollution. Enhanced microbial activity due to climatic effects eventually degrades the pith. Coir pith is recalcitrant and accumulates in the environment forming hillocks posing environmental pollution in the areas close to coir fiber extraction units. In this study, 4 samples of coir pith at different stages as a function of time were selected and the chemical contents were compared for the degradation studies. It was observed that the raw coir pith contained higher chemical contents. Therefore, coir pith can be treated with the help of microbes in the raw stage itself and can be used as the raw material for plant growth in an eco-friendly way.
Keywords— Cellulose, Coir pith, Electrical conductivity, Lignin, pH, Total dissolved solids.
