We can setup plants at all the banks of drains which are falling into the Ganga directly or its tributaries and can stop this liquid waste polluting Ganga. The amount of useful products which are generated can change the topography of the region, says Ajay Girotra, Managing Director, AG Dauters Waste Processing Private Limited, in conversation with Gautam Debroy of Elets News Network (ENN)

“To become and qualify as Smart City, we feel the cities are concentrating on superficial things like first installing street lights and converting them into LED lights and installing CCTV cameras at the road intersections.”

The mission of AG Dauters is converting waste into energy. Kindly tell us about it.

The world is trying to reach new frontiers every day in every field and make life easier while making us smart. But at what cost? If we see, we are actually back to basics.

Today, we are fighting for our basic requirements: clean air, water, and food. Our basics are highly adulterated, polluted environment. Soon, cities will be fighting for survival for clean air and clean water. Our mission is to provide clean air and clean water. It can happen when we stop rampant use of fossil fuels, clean our cities of its waste and clean our sewages and effluents which are polluting our rivers as well as the groundwater. We are making it possible through our zero emission, zero residue waste to energy technology, which not only provides pure drinking water, but zero carbon fuels and green power.

A smart city needs selfsustainability. What is your take on it?

Let’s talk about what smart city stands for. India is a country of huge disparity. On one side we talk about technological advancements of launching 104 satellites in a day. On the other side, over 60% of our population does not have access to basic needs like clean food, water, electricity and basic hygiene. For sustainability, every person, every village, town or city requires clean air, clean water and clean food and if we are able to do….that’s where the smartness starts.

How can AG Dauters help a city in becoming self-sustainable?

Every city generates enormous amount of solid, liquid, effluents, bio and other hazardous and toxic wastes, which are being dumped either in landfills or thrown in rivers. All these wastes are full of energy and can provide 24 x 7 x 365 days of power, pure drinking (mineralised) tap water and zero carbon fuels for the city.

The cities can forget what is a power cut, what are generators or invertors, what is hard water, what are water purifiers, what is 02 -04 hours of sweet water supply, what are the emission norms of vehicles, what is black smoke coming out of diesel vehicles, what is refilling of gas cylinders, what is fetching of fuel for cooking, and what are inorganic fruits and vegetables?

The municipal, industrial and medical waste of each city, which are the biggest nightmares today, can become the feeders of the city by producing energy. Our technology and plants produce mineralised drinking water, power and zero carbon fuels in enormous quantities, good enough to make any city self sustainable.

For example, from 30 mptd (metric tonnes per day) of solid waste or 01 mld (million litres per day) of liquid waste, our plants generate 10MWh of power. Mineralised and oxidised drinking water, and zero carbon fuels are produced in enormous quantities. Zero carbon fuel can be given as Green Diesel, or piped into homes as cooking gas or can run the vehicles as CNG.

Fuel can also be given as Jet fuel for the aeroplanes. Our plants do not produce any kind of emissions or flu gases or any kind of residue. So air, soil and ground water do not get polluted. Large quantity of land is required for disposing of solid wastes and inerts which take away precious fertile land. Urban areas in India generate 1,70,000 metric tonnes of MSW every day and that requires 3,40,000 cubic meters of landfill space everyday ( 62 million tonnes disposal every year requires 3,060 acres every year ). All this can easily be saved and converted into Aquaponic food farms which will produce organic foods: fruits, vegetables, herbs throughout the year, without the use of any pesticides or insecticides, thus making the cities true smart cities.

As you are into the business of converting waste into energy, how can you help in clean Ganga Mission?

About 12,000 million litres of sewage is generated in the Ganga basin every day, of which 3,000 million litres per day falls into main stem of Ganga every day from class I & II towns. Out of this, 20% is highly toxic and bio-degradable in nature. Let’s look at what is the potential of this waste which is polluting our most holy river (Ganga) if treated and processed with our technology:

  •  1,50,000 MWh of green power
  • 8000 mld of mineralised drinking water ( 800 cr litres )
  • 3400 mld of fuel ( 34 cr litres )

We can setup plants at all the banks of drains which are falling into the Ganga directly or its tributaries and can stop this liquid waste polluting Ganga. The amount of useful products which are generated can change the topography of the region as well as contribute to the exchequer in a large way, directly & indirectly.

What are the challenges the smart cities in India are facing?

Roads properly lit with proper policing, maintaining traffic signals and rules are basic requirements which in past have not been fulfilled. Cities should first clean up their waste, this will help in cleaning air and water and improve the environment followed by laying down and implementing strict rules traffic rules, maintenance of the public areas and properties, strict adherence to government programs for Reduce, Reuse, Recover, Recycle and Remanufacture. This is when they will actually be called SMART.

What differentiates you from other waste into energy converting agencies?

Let’s understand what is the world of waste to energy and what are the technologies which are being used. Broadly, the technologies being used can be classified as:

For Solid Waste:

  • Bio-chemical conversion of biodegradable MSW which includes composting and biomethanation
  • Thermal processing of MSW : includes technologies like gasification, pyrolysis, incineration and mass burning

For Liquid Waste:

  • Stp’s or CEPT’s

Our technology is based on plasma gasification, which is a new paradigm in Thermal processing and is integrated with our proprietary processes which takes care of both solid and liquid waste of all kinds at the same time.

In our technology, we do not burn anything but solid and liquid is segregated and solids are converted into syngas with zero emissions and zero residues. The outputs which are generated are Power, mineralized drinking water and zero carbon fuels in enormous quantities…almost 80-100 times more than the nearest technology. The key features of our technology are:

  • No segregation of waste
  • Any level of moisture is acceptable
  • Calorific value has no meaning
  • No landfills l Small footprint required for the plant
  • No emissions l No residue
  • Power, drinking water and fuels are the outputs
  • Apart from solid and liquid waste, we process any kind of hazmat, toxic waste, seawater, lake or river water, bio-pharma / medical waste or in simple terms anything which is not fit for human, animal or plant consumption are treated and processed in our plants.
