Waste to Energy Plants and Why are People Protesting Against Them

Waste to Energy Plants and Why are People Protesting Against Them

Articles
A Waste-to-Energy Plant is a waste management system where waste is burnt to produce electricity. These plants usually burn municipal waste. The various techniques used in Waste-to-Energy (WTE) plants are biomethanation, combustion, gasification, pyrolysis. Non-recyclable and not-hazardous wastes should ideally be burnt in this process. The waste to energy plants comparatively release less pollution than a coal-based plant.

Tihar Jail is known to every Delhites but how many Delhiwalas are aware about Tihar Jheel. Not many, I guess. It is another lake in Delhi that we lost. Tucked away in a corner of Hari Nagar in West Delhi, the Hari Nagar Lake or Tihar Jheel was a serene wetland bustling with migratory birds basking in the winter sun not many years ago.

Among the water birds Painted Stork, Indian Spot-billed duck, Northern Pintail, Black-winged Stilt used to throng this lake in large numbers. The year 2012-13 was the most exciting when one could even spot Mallards and Great Cormorants here. Tihar lake also used to have a vibrant winter, ...

Stubble burning around Delhi during October 2018. Winter is peaking in Delhi these days and the air pollution this year has been more engulfing than ever.

Delhi Government Goes All Out to Ensure a Clean, Green Diwali 2018

The festival of Diwali is no longer a festival of joy alone and is accompanied by misery especially for those suffering from breathing disorders. This is true for the entire NCT of Delhi, which has an alarming population of over 20 million people. Every year during Diwali, the air quality worsens and is worst during and immediately after the Diwali night. The large-scale burning of fire crackers during the Diwali night, which spikes up the already air polluted National Capital is the principal cause of this pollution. This year, the Government of NCT of Delhi has taken significant steps for ensuring the reduction of air pollution due to Diwali. The Government began with writing a letter to all the schools, through its Eco Clubs Scheme. The Deputy Chief Minister of Delhi Shri Manish ...

Oriental Apartments Leads the Way in Holistic Waste Management

Articles
Oriental Apartments in Sector-9 of Rohini celebrated the Independence Day this year with another freedom. This was the freedom from the burden of sending thousands of kilograms of solid waste to the already overflowing landfills in Delhi. In doing so, Oriental Apartments showed the way to other Resident Welfare Associations (RWAs) and colonies on what needs to be done to solve the ongoing waste management crisis in Delhi. Waste management is perhaps the greatest environmental challenge being faced by Delhi, yet one which is least discussed. The waste of Delhi has already created three giant mountains, taller than 80 feet in height, and these landfills have also become killer and are now coming down as landslides. There is thus a need for disruptive innovation in the waste management...

As we walk along the roads of Delhi, there are some entities calling us and crying out for help. They are moaning of the dreadful death we are thrusting on them from suffocation and starvation, slowly and painfully. We cannot hear them because they cannot speak. They receive our attention only when the services they render to us start falling short for us. Yes! I am talking about those magical devices on the sides of roads, in front of shops, in our backyards, around our institutions, in areas of traffic, which keep imbibing the notorious carbon dioxide for us and continue to give oxygen that we terribly need. Our Trees! This time the concrete is killing them, a dire threat to the survival of the same entities that give us food and oxygen. Trees are choking to death, their roots ...
