A Study on Recycling of Saw Dust and Pollution-Free Indian Railways

Abstract

The Madurai Kamaraj University is situated in Madurai town, Tamil Nadu state, India is an urban area has geographical Location of Latitude 9.941418, Longitude 78.008896 and GPS Latitude coordinates - 9° 56’ 29. 1048 “N and Longitude 78° 0’ 32.0256 “E. The population in Madurai metropolitan town is around 14, 65,625 Lakhs (in 2011 census)-[Male-7, 33,821 Lakhs and female-7, 31,804 Lakhs]. The study of air pollution in this paper consist of two parts- One part deals with (1): The survey of Improved air quality dedicated to nation by Indian Rail Transport (98.5%), in outdoor air pollution control, which is done by a conversion process of electrification implemented in all rail tracks in India - and other part deals with (2): Indoor air pollution generated in a saw mill may be handled by best solid waste recycling process of – compost method for agricultural usage. This study of saw dust recycling is come under the Indoor air quality engineering .The Indoor air pollution is very important because the outdoor air pollution is lower than Indoor air pollution. Also, the outdoor air is a source of supply of air to indoor environment in a house/ Industry. In general, the saw mill generates more amount of saw dust per year. The solid waste of saw dust is disposed by open firing method, creates air pollution in local atmosphere and creates lot of health problems to working people inside and surrounding living people nearby saw mill in an urban area. The saw dust mixed with (cow + goat dung) is completely converted into natural fertilizer for agriculture. This study also focus on The Indian railway introduces electrification in rail track (except Rameshwaram) in several routes and ensure air pollution free zone that is zero percentage carbon emission zone.
