Waste Management in India needs scientific approach

India need to improve it's waste management as the metropolitan cities are expanding at a faster pace than the preparedness of it's municipal bodies.

Waste Management in India is only about collecting and dumping the garbage at a location in the proximity of a respective city. There is no treatment of waste and recycling it, as there is no system in place where the trash is separated and collected.

Government of India is neglecting an important issue as it could lead to soil degradation, and also leading dangerous pollutants entering the water system of areas surround the garbage dumping sites. There are several reports in these regards and all the response from municipal bodies is stop gap approach and no scientific and sustainable approach to the problem.

Many countries have offered India technology to treat it's waste generated. But respective governments have neglected the issue.

Why in the world our governments first let the situation go out of hand and pay huge cost later on and seek help from other countries.

Classic example is the situation of river Ganga. Now after decades of neglect, the government has suddenly shown interest in cleaning up, but the cost and effort will have shot up by now, by what it was earlier and also pollutants could have affected the population more than anybody could imagine.

India is developing at a faster pace and the population will shoot up, which will further increase the burden on the municipal bodies to manage the system.

Columbia University Research Paper on Sustainable Waste Management in India

An Excerpt from the Research paper by : Ranjith Kharvel Annepu

This report is the result of over two years of research and includes data collected from the literature, communication with professionals in India, US and Europe; and extensive field investigations by the author in India and the US. Two field visits in India over a period of fifteen weeks covered 13 cities (Figure1) representing all sizes and regions in India. The visits included travelling to informal recycling hubs, waste dealers shops, composting facilities, RDF facilities, WTE facilities, sanitary and unsanitary landfills, landfill mining sites, and numerous municipal offices. These visits provided the opportunity to closely observe the impact of waste management initiatives, or lack thereof, on the public in those cities.
The author has also visited different WTE plants in the US to study the prospects of this technology in India.

Working more than 20 hours a week in high school found harmful

ScienceDaily (2011-02-04) -- A new shows that among high school students, working more than 20 hours/week during the school year can lead to academic and behavior problems. The researchers used advanced statistical methods to reanalyze longitudinal data collected in the 1980s on 1,800 middle class teens in 10th and 11th grades.
