AG Dauters presents the most advanced waste to energy technologyfor India: Solid and Liquid waste with Zero Emissions and Zero Residue, says Ajay Girotra, Managing Director, AG Dauters Waste Processing Private Limited, in an interview with Gautam Debroy of Elets News Network (ENN).
How would you describe the overview of AG Dauters Waste Processing Technology?
AG Dauters waste processing is the India arm for Langenburg Technologies USA. Langenburg has come out with a very breakthrough proprietary technology to convert any kind of waste into power, drinking water and fuel. So, when we say ‘waste’ we mean in any kind — solid, liquid, effluent, slags, fly ash, bio-waste, hazardous, toxic, slurries or sea water, ocean water. Anything in the world which can be termed as waste, we convert it into three things: Power, Drinking Water and Fuel. The key USP of our technology is, it is zero emission – zero residue: nothing in the ground nothing in the air, no residues at all. We don’t require any kind of a start up power. We create our own fuel. Land required is about 1/10th to 1/20th the conventional size of a RE or thermal plant. So, it has got a very small footprint. And, what we bring to India is at zero cost, meaning there’s no government investment required, no kind of support . Only three outputs which we produce is what we sell to the government and that’s our commercial model.
How is this waste to energy technology different from other technologies available in the market?
Our waste to energy technology is absolutely way ahead of what the existing technologies are. For instance, in case of solid waste, it is the incineration technology. Incineration has a few big problems namely:
1. It can only burn the organic waste. A separate landfill is required for the inorganic/ inert to be disposed off and it creates a huge amount of residue which again requires the landfills.
2. It requires absolutely dryness. So moisture is a big hassel.
3. The kilo calorific value. It has to be more than 1,200 kilo calorific value to process that waste.
4. Large amount of land required for the landfills.
In our case, none of these four are required.
a) We do not require any kind of segregation. We process inert, organic, inorganic, anything and everything we process it out.
b) Moisture is absolutely friendly to our technology. Any level of moisture is fine with us.
c) We do not require any kind of landfills because we do not have any residues left out.
d) And kilo calorific value does not matter to us, as we are not burning. Our process is Plasma gasification where each an every matter is broken down into its molecular form and in that molecular form at a very high temperature we are able to convert it into the syn gas.
In case of liquid waste, the problem is that solution available is only STPs which, in turn, just filter the waste and are energy guzzlers. Sewage treatment plant is not the solution for it. It is just simply filtering the waste.
Our technology is the only one in the world which can convert sewage into power, drinking water and fuel. For example, in solid waste a 200 metric tons unsegregated waste generates about 1-2 MW of power. In our case, 200 metric tons of unsegregated solid waste generates 70 MWof power.
We are almost 70 times. In case of liquid waste from 01MLD which means 10 lakh litres of sewage, we are able to generate 10 MW of power and about 9,50,000 liters of drinking water and fuel. This is absolutely unheard of, and this is breakthrough technology which our company has created and that is what we are presenting to India now.
In which parts of India are you planning to set up the plant?
Also tell us about its operational performance. The key thing about our plant is that it is absolutely integrated technology right from the segregation of water and the waste to the production of the three outputs. We require such low footprint that for example a 50 MW plant requires only 10 m x 10m of building.
So, we put up our plants at the pit sites where the waste is available. Currently, same is the case with solid waste, the plants are put up at the pit sites because the space required is very less. We are currently in discussions with the governments in Maharashtra, Uttar Pradesh, Punjab, Jharkhand, Haryana, Madhya Pradesh, Telangana. We are in the process of signing up projects where we are converting solid waste, affluent, sea water, sewage into the three outputs. And all our plants are completely computer controlled and connected to our central servers through our own satellite.
Most of the waste to energy plants established earlier have either closed or are not performing as required. In this situation, your technology could be of great use. What government support you require so that it helps society in waste management as well as energy development?
We need to understand why the plants, which were set up, exited, closed or not producing what they are intended for. We need to understand what the problem is? And, that is burning of waste. Burning the waste does not generate so much energy that it can be commercially sold and make money from. Plus, they generate huge emissions as well as residues .That’s the reason they were not commercially sustainable. That’s the reason they exited out. What the Government has to see is that the water, air, and the earth are getting heavily polluted day-by-day.
Everywhere the groundwater is heavily polluted due to leachate discharge from the east landfill sites. The water is not going to last for long, and the air we just saw what the smog in Delhi was, the amount of pollution which is getting caused now, this is not going be getting reduced. It’s going to increase year by year. The Government has to understand there is need to adapt newer technologies and what is the potential of the waste. Today, waste can replace any and every kind of fossil fuel.
Waste management is something about how garbage waste can be used as some valuable resource and as your tagline says “the most powerful thing in the world is water.” What would be your action plan to implement this technology on a larger scale?
We need to understand how powerful the water is. For example, 14,000 million litres per day of sewage falls into the Ganga river everyday. What is the potential of this sewage? The potential is if we process this entire waste, we will be generating 50,000 MWh (MegaWatt per hours) of power. We would be generating 100 litres of mineral water per Indian per day. The entire consumption of diesel and jet fuel of this country can only be made from this sewage. Another example of power of water is the amount of sewage falling into Bellundur lake. You have heard of this lake in Bengaluru, which catches fire there. It can generate 5,000 MWh of power to lighten up the entire Bangalore city.
It can give 30 Crore litres of drinking water to Bengaluru and Kolar areas, as well as supply diesel, jet fuels, or CNG for the entire city. That’s the potential and we are able to easily scale up.
How will your technology and plants help in strengthening the Swach Bharat Abhiyan?
Swach Bharat Abhiyan is an absolute fantastic program introduced by the government. It’s making people aware of what is the importance of cleanliness and making everybody do cleaning of their entire cities and town.
But we find it, it is an half-hearted affair because it is teaching people to collect the waste. But it is not teaching people how to process the waste. Cleaning the city and collecting the waste and throwing it in the landfill is not the solution.These landfillsare causing so much of pollution the leachate which is going into the ground is contaminating the ground water. The sewage which is getting generated out there is going into the rivers. That has to get eliminated and once that gets eliminated and gets converted into energy that is what actually the Swacch Bharat Abhiyan will be and India will be called the “the most smart country”.
