00:17Hi, good afternoon to all our viewers, I'm Suesha Samth and this week on Pollution Ka
00:21Solution we are talking about the solutions that could potentially work in Delhi's pollution
00:26hotspots. We bring you four such suggested innovations from giant air filtering cubes,
00:33two technology that claim to reduce our exposure to pollution, two devices that can turn a car
00:39into a moving air purifier and even a system that combines air filtration with renewable energy.
00:46Let's find out together how practical these solutions are. First we begin with a technology
00:53that has already been tested in one of Germany's pollution hotspots. In 2018 and Stuttgart emerged
01:00as one of Germany's worst affected locations for particulate matter and hazardous gases. The
01:06response was not just to measure the pollution but to try and tackle it at the source. German
01:12filtration specialist Mann plus Hummel deployed its innovative filter cubes designed specifically for
01:20pollution hotspots and aimed at improving local air quality and the company says the results were
01:26significant. Now Rajan Honda, managing director of OK Play in India believes that Delhi needs solutions
01:33that are not just innovative but already tested in the real world. For him Mann plus Hummel's filter cube
01:41is one such possibility but can a technology designed for pollution hotspots in Germany have a role to
01:46play in a city like Delhi. Let's find out.
02:03My name is Rajan Honda and I am the director of MRS Technologies Private Limited.
02:11MRS Technologies Private Limited is the exclusive partner to Mann & Hummel Germany for the manufacturing,
02:18selling and servicing of their air filtration products for India. Mann & Hummel is an
02:2480-year-old German German MNC which is working with 80% of the ratio of the population.
02:34air pollution is now actually the price that we pay for development.
02:39The amount of our infrastructure is developing, whether there are road buildings, bridges, metro,
02:46some buildings, offices, residences, these are all that contribute to pollution.
02:53The fact is that we are doing this campaign
02:55is really, really remarkable because we all need to understand. It's just not the government
03:02which has to do this. It's a public-private participation where we all must be aware of the
03:07a. the consequences of pollution and b. how we can mitigate those risks.
03:12This product you are watching behind me is called filter cube. This is used by forced air circulation
03:18technology technology and b. How we from работать air accuracy. The boat is forced to be outside local
03:24mountain where there is also filters and they can build PCs line up 비-ンダ援-
03:35which are all needed for everything inilan horrors in the gas sector.
03:42So, one of the rapid things they also been trying, Xamah and let it rip out water law
03:44is basically new in fact which the air and air Arabia has detected it across the globe.
03:47The road is seen by dust and smoke, including some gases such as NO2 or SO2 which are harmful
03:56are also captured.
03:58This technology has also been validated by IIT Delhi.
04:02This has been done by September to November, in the peak pollution period.
04:10We have provided a school in the IIT, which was put in the equipment and cleaned the whole air.
04:2160-70% of the population has been reduced by a normal citizen.
04:29The most important thing is that the engineers have been in Germany, but they have been manufactured in India and
04:36assembled in India.
04:38The cost of production is also very reasonable, and its availability is also very good, and servicing is also very
04:45good.
04:46There is no experimentation going on.
04:48There is no such thing that we have come up with a new innovation.
04:51We cannot afford a new innovation.
04:53We are fighting a very, very real problem, and we have to address the real problem by the real solution.
04:59In my opinion, this is not an exercise that you could carry for scientific development.
05:05It is an exercise that you have to carry, keeping the health of the citizens in mind.
05:18I am Priyanka Manocha, founding team of MRS Technologies Private Limited.
05:24And on my right is Pranav Kaushik from our partner company MAN & Hummel.
05:30And he is Steven, another employee colleague from MAN & Hummel.
05:36So, together we bring to you the pollution ka solution that you see behind us, which is called as Filter
05:43Cube.
05:52I am a mother of a nine-year-old daughter.
05:55And she is today living in Delhi and smoking equivalent to 80 cigarettes a day.
06:02My child is closed when the pollution increases.
06:07Most of the time, she has to study her at home.
06:10And these are the early learning years, which is shaped by her personality.
06:16That's why she has to spend more time on her at home.
06:19This is a very big problem.
06:21Today, when I stand here in front of you, I may appear to you as a young person,
06:27but my inner health today has deteriorated to a level that I have lost 12 years of my life.
06:38This one machine that you see behind me is almost 17,500-meter cube of clean air every hour.
06:46If you want to understand it in liters or if I want to give you a perspective of it,
06:52In a cricket stadium, the amount of water is filled with the amount of water every hour.
06:56So, this one machine is cleaned in the area.
07:00So, we use multiple machines like this.
07:02So, what we try to do is create a clean air zone for that area.
07:07So, the localized pollution that comes to people's limits.
07:15This device is so intelligent.
07:16When it is raining, this device switches off.
07:19Meaning, when it rains, we don't want the air purifiers to be working.
07:23So, the device switches off on itself when it rains.
07:27And also, when the rain stops, the device switches on on its own.
07:31In this device, we also have a night mode.
07:35Meaning, at night, when we don't have any dense population around,
07:41we can bring down the speed of the fan to around minimal,
07:45where we don't need much clean air coming out of the system.
07:48It does all on its own.
07:51And also, we have a centralized dashboard.
07:54Meaning, when we have 100 installations at different places.
07:58Cannot Place, A Block, B Block, C Block.
08:00We can put it in any area.
08:02Then, we can give you a dashboard in one area.
08:05We can give you a dashboard.
08:07We can give you a data on every product level, zone level, and also as a city level.
08:17Delhi's ambient air remains unhealthy for large parts of the year,
08:21with consequences that go beyond just what we breathe.
08:25The question, therefore, is whether we can find solutions that work throughout the year,
08:30particularly at pollution hotspots where people are exposed to higher concentrations.
08:35Rajiv Chanan, an innovator based in Gurugram, claims to have developed a technology designed
08:40for year-round use, the idea is simple, identify where exposure is highest and intervene there.
08:47But how does the technology work and can it make a meaningful difference to the air we breathe?
09:12My name is Rajiv Chanan and I am the founder and managing director of Human-Dust Technologies,
09:19which we formed in 2018 with the objective of developing innovative technologies
09:25in the field of energy and environment.
09:28The area of Delhi is 1500 km2.
09:31There are about 1,000,000 liters of petrol, diesel and CNG every day consumed.
09:40So generally Delhi's dimension is very big if we look at it from a pollution standpoint.
09:47So not only controlling AQI, but controlling exposure is also important.
09:52So in effect, Delhi requires, in our opinion, a permanent structure,
09:58permanent infrastructure to control air pollution which is coming.
10:04So our technology objective is to reduce exposure reduction.
10:10Policy implementation, policy thrust, new policies are very good to control overall ambient to reduce pollution.
10:18APS stands for ambient purification system.
10:21It is partly meant for particulate matter.
10:26An idea behind this is that we are supposed to make a system and technology for outdoor where you install
10:34it once
10:35and it should continue to run without any attention intervention for 15-20 years.
10:41Because the minute you put something in outdoor, it has to be sustainable
10:46and it should not require frequent attention.
10:50And we designed the storage capacity to be roughly three to five years
10:55so that nobody needs to go in and service the equipment, you know, every now and then.
11:01It would once required in one in three years or one in five years.
11:06And then particulate matter, safe disposal of the material.
11:11So we still need to figure out what does it contain.
11:13It may contain many other particles, many other elements which may not be,
11:18you know, good for human health.
11:20So it has to be disposed.
11:22So idea behind was that we should reduce exposure to the people
11:27and hence the machine should come closer to the people.
11:31Wherever, in outdoor, there are large people like ISVT, railway station, market places.
11:39We should bring equipment closer to the people, reduce their exposure.
11:44That in APS, there is no filter in any way.
11:48So this means that you have to understand the most important thing in the outdoors
11:53that they will choke in two or three days
11:55or that their performance air delivery is reduced.
11:59So this means that there is no difference.
12:01There is a consistent performance in 15 years
12:05in all of the pollution levels
12:09and in all of the weather conditions.
12:12So it does not mean that the performance will come in the rain
12:15or in the summer or in the winter.
12:18It does not mean that the principle that we have used
12:21is the basic physics principle.
12:23that your particulate metal is heavier than air molecules.
12:29So you can suck air in a particular velocity
12:32with a particular angle.
12:34So that the heavier metals and heavier particles
12:38like PM2.5 and PM10
12:40they cannot travel the path of the air being taken into the system.
12:45So they tend to get separated from the balancer.
12:49So they tend to get separated from the balancer.
12:50So they also have agglomerate.
12:52So we have designed the wind tunnel design
12:54that there are two aspects.
12:55The first is that it agglomerates
12:57and the second is that the heavy particles
13:00reduce the velocity of the heavy particles.
13:02And when it comes to an area,
13:04it's low velocity and it's settled.
13:07So this is the principle of making the heavy particles
13:10we can separate it without any filter.
13:21Now imagine if the vehicles on Delhi's roads
13:25could do more than just transport us.
13:28What if instead of only adding to the pollution around them,
13:31they could actually help clean the air?
13:33A Delhi-based NGO, Shud Vayu,
13:36is working on a device that it says
13:37can be installed on the roof of a car
13:40and used to reduce particulate pollution around it.
13:44The organization claims its system is detachable
13:46and can be installed or removed in about 60 seconds.
13:50So could a car become more than
13:52just another source of emissions
13:54and actually become a moving air cleaning unit?
14:06My name is Sanjeev Kumar Yadav.
14:09I am a graduate of Mechanical Engineering
14:13and I am a graduate of SUD Vayu Technologies Private Limited.
14:17As a technology head and founding member,
14:21I am working on it.
14:22I am Dithi Bhatnagar.
14:24I am Biotechnologist and Masters in Business Administration.
14:27I am a co-founder of SUD Vayu Technologies.
14:29Me and my team headed by Mr. Amit Bhatnagar
14:32who is an ex-IITN.
14:34We are working for air pollution problem.
14:43We are working for air purifier on Sud Vayu.
14:44When we started working on Sud Vayu
14:45with vehicle mounted air purifiers,
14:50we started working on a deployable,
14:53visible and scalable solution.
14:56in this context we have developed without any external energy, without any digital or permanent
15:06structural or any fitting, this retrofit device we have built in the car, which you can
15:13put yourself in the car and you can put yourself in the car. When in Delhi there is pollution,
15:18you can put yourself in the car, but if you don't have pollution, you can put yourself in the store.
15:23We have been able to put your vehicle in the car, which hardly has one square foot space.
15:30We have piloted the GURUGRAM Municipal Development Authority, which we have put in the car.
15:41If we are talking about BS4 vehicles, the PMMation norm is 25 mg per km,
15:48per kilometer होता है और हमारा डिवाइस जो है वो 50 मिलीग्राम पर किलो मीटर कर रहा है तो कहने
15:54का मतलब जैसा कि हम लोग बात करते हैं कि वेहिकल पॉल्यूशन फैलाता है वेहिकल पॉल्यूटर है लेकिन विद्धा सुधवायू
16:02डिवाइस वेहिकल एक नेट एर प्यूरिफायर में
16:08वेहिकलर एमिशन को टार्गेट नहीं कर रहे हम किसी भी सोर्स से पॉल्यूशन हो रहा हो क्योंकि दिल्ली में वेहिकल
16:15से पॉल्यूशन का जो कॉन्ट्रीबूशन है वह एप्रॉक्स्मेटली 20 परसेंट है उसके बाद रोड डस्त है उसके बाद इंडस्रियल बर्निंग
16:23ह
16:30वेहिकलर एमिशन को टार्गेट नहीं कर रहे हैं तो हम कहने के मुलब यह है कि एक पॉल्यूटर को हम
16:35एर तुरिफायर में कर रहे हैं जो कि दिल्ली के लिए बहुत कारगर हो सकता है
16:50इस टेक्नोलजी में हम कोई भी फैन, इलेक्ट्रिसिटी, मोटर, बैटरी कुछ यूज नहीं कर रहे हैं
16:56यह जो ओड़ेडी हमारे इंवायरमेंट में एर प्रेशर, एर कानेटिक एनरजी अवेलेबल है
17:02जब गाड़ी चलती है, तो अगर इवन वो गाड़ी 40 की स्पीट से भी चल रही है, तब भी अगर
17:06आप अपना हाथ भार निकालेंगे, तो आपको एर प्रेशर फील होगा
17:09तो हमारे इंवायरमेंट में औरड़ेडी वो एर प्रेशर एवेलेबल है
17:12तो उसी प्रिंसिपल को यूज करके हमने यह एर फिल्टर इनोवेट किया है, इसको जब गाड़ी के उपर लगाना है,
17:19कोई प्रेशर से एर अंदर जाती है, कार्बन पार्टिकल्स को चैप्चर करती है, जिसमें डस्ट प्री फिल्टर भी लगाया हुए,
17:30जिसमें जो ला
17:42और clean air बाहर निकलती है, जब वेहिकल से associated कोई भी solution आता या technology आती है, तो वेहिकल
17:49अपनी वेहिकल से emotionally attached है, क्योंकि वो कोई भी चीज उसमें fit करने से 10 बार सोचते है, तो
17:57हमने उस सोच के साथ इसको डेवलपिया है, कि इसमें हमने ऐसा नीची आइसा प्रोविजन रखा है
18:04अपने डिवाइस के, कि ये एक single scratch, single pin भी गाड़ी के छट पे कोई एक single, हम ना
18:14तो कोई छेद कर रहे हैं, कोई drilling कर रहे हैं, ना तो इससे कोई हम scratch आने का कोई
18:20भी उसमें chance रख रहे हैं, इसमें चांस रख रहे हैं, इसमें self-installable, चाहे senior citizen हो, चाहे lady
18:25हो, चाहे कोई student हो, को�
18:30क्योंकि most of the solutions, जो है, वो static है, यह हम existing जो गाड़ियों अरड़ी गोड़ पे चल रहे
18:36हैं, हम उन गाड़ियों को air purifier में convert कर रहे हैं, तो it is a very very novel and
18:41bigger innovation than any other available technology, अप्रोक्समेटली हम लोग 7000 रूपीज का जो costing है, वो हम लोगो कर
18:50रहे हैं, और हम target जो कर रहे हैं, जो हम इसको �
18:55प्राइस को बोल सकते हैं या जो भी, तो वो एप्रोक्समेटली हम 10K के आसपास अभी लगते हैं, क्यूंकि इसके
19:01sizes vary करते हैं, गाड़ी के size के हिसाब से, तो हम इसको 8000 में, 10,000 में और 12
19:07,000 में अभी cars के लिए रखे हुए हैं, और बसे में हम एप्रोक्समेटली इसको 22,000 क
19:12अभी कर रहे हैं, जब मूविंग होगा तो लोगों में अवेरनेस हाई कि और पॉल्यूशन इस सम्थिंग जो लोगों की
19:19हेल्थ को बहुत बुरी तरह एफेक्ट कर रहे हैं, और लोगों को अभी लेलाइस नहीं है, तो उस उस अवेरनेस
19:24को बढ़ाने के लिए भी ये solution ब
19:44But when we talk about a solution to pollution, there is another question we need to ask. Is it sustainable?
19:51Because a solution cannot simply solve one problem by creating another. And that brings us to our final innovation. Aerobos,
19:58alongside with IIT Kanpur, has developed what it calls a wind panel, a rooftop filtration technology designed to clean air
20:05while a vehicle is moving. But there is another element to it. The system combines air filtration with renewable energy,
20:12energy generation, using both a solar film and a wind turbine. So can one technology potentially tackle pollution's exposure while
20:21also generating clean energy?
20:33My name is Gangesh, by profession I am a Chartered Engineer. I have done my Masters in Energy and Power
20:39from University of Liverpool.
20:42I have been born and bought up in Delhi. So, I have been born and bought up in Delhi. So,
20:45I have seen pollution problems here. So, I have seen a lot of pollution problems here in my childhood.
20:48So, I have seen a solution for the future, for the future generation to clean air and clean air. So,
20:55I have made a solution for our next generation, which has been called Wind Panel.
20:57What is the name of Wind Panel?
21:00What is the name of Wind Panel?
21:01This idea that I have made my Masters in University of Liverpool.
21:05I have made my Masters in University of Liverpool.
21:07When I read this idea, this idea came from that, that the buses can also add a product to the
21:13city's pollution.
21:14I have met him and my co-founder, Akshansh, and I have made this product in the past 7 years.
21:19We are made this product.
21:22In Delhi, like a city, where we have a challenge, where we are not using the land, we are not
21:30using the video,
21:31because we are making the video, which is offering the filter.
21:35And the land, which is a big challenge, is not used as our device is a mobile mounting, which is
21:42just on the rooftop.
21:48It is a retrofitted device.
21:50So, we place this product on the bus.
21:53And for maintenance, we have electrostatic plates, which we can clean with brushes.
21:58There is no replacement cost of the filter or maintenance.
22:02We have to clean the filter for 2-3 weeks, for a week, for a week.
22:07And we have prepared for the next journey to clean air.
22:11So, we can clean the filter for 2-5,000,000,000 m3 of air in a day.
22:22And with that, it produces around 2-3 kW of energy, which also produces a product.
22:28If we compare it with 5 solar panels, then it comes together with a wind panel.
22:59That's all for this hour. Keep watching India today for more news and updates.
