It appears that our understanding of the urban ecosystem in our cities will continue to limit our competence in providing environmentally and ecologically sustainable alternatives for urban habitats. One solution, experts argue, is to go vertical, while improving all the other needed services like roads, water and waste disposal.

A recent report datelined Bathinda, filed by TNS correspondent S.P. Sharma appeared in The Tribune dated October 31 describing the situation at Bathinda City:

From wasteland to a green hub

A field experiment was conducted in Allahabad District of Uttar Pradesh to test the possibility of utilizing fly ash, in afforestation of sodic soil with Albizia procera, as a substitute of fertilizers and amendments. Fly ash proved to be a good substitute of rice husk, was superior. Similarly the treatments where fertilizer was replaced with fly ash have also shown better performance of plant.

BANKURA: Power generation at the Mejia Thermal Power Station (MTPS) may be hampered following disruption in ash evacuation by the villagers who have stopped transportation of ash from the ash ponds since yesterday alleging environmental pollution. Villagers have demanded immediate rehabilitation before evacuation of ash.

Whereas by notification of the Government of India in the Ministry of Environment and Forests number S.O.

The use of heavy metals along with the associate risks of metal pollution has increased to a great extent over the recent times. Cadmium is one of the most harmful toxic metals. This metal is being increasingly consumed in the industries. Its pollution potential, has therefore given rise to the necessity of removal of cadmium from wastewater.

The objective of the present study is to assess the migrating behaviour of nickel and chromium through the soil collected around an ash-pond site through laboratory studies and an undertaking of contaminant (Nickel and Chromium)- soil interaction phenomena for unraveling the transport mechanism of nickel and chromium through soil and ground water with an attempt to validate 2 D mathematical modeli

It may be just a byproduct, but the state government has earned Rs 15 crore out of it. The fly ash from the thermal power plants in the state, once a major air pollutant, has now become a gold mine as construction companies and cement manufacturers compete to take a major chunk of the byproduct. The AP Power Generation Corporation (Genco) has earned Rs 15 crore by selling this fly ash. This is usually used to make bricks or add as a mixture to cement, used for construction or laying roads. More than nine million tonnes of ash was sold this year by Genco.

Fly ash is an industrial waste generated from thermal power plants. A large part of fly ash produced is disposed of with very high environmental risk.
