Energy saving 'Vayu'

- Nowadays-Preity Shah

- If sanitary pads are not disposed of properly, they pose a threat not only to landfills, but also to water bodies and livestock.

In today's world, it has become imperative to plan for the increasing demand for energy as the driving force of the individual and society. Today we are very concerned about the problems caused by climate change, but only a few people are aware of their responsibility and are constantly trying to protect the environment. One such person is Priyadarshan Sahasrabuddha of Pune. I.I.T. After studying in Mumbai, Priyadarshan worked in his father's auto component manufacturing company, but he was always concerned about his surroundings and the increasing pollution. He visited Dr. Happened to Anand Karve, who was working on biogas. Under his guidance, Priyadarshan built a small device that could make biogas and named it 'Vayu'!

e. S. After making this machine in 2015, got knowledge about the capabilities of biogas. He believed that this was cow dung gas, which could be used in rural areas, but after making 'Vayu', it was felt that it could be used as a fuel in urban areas as well. After using a device called 'Vayu' in his home, he also made this biogas device for friends and relatives. This device of Priyadarshan is such that energy can be generated from it by installing it in the balcony of the house.

The design of the 'Vayu' machine is such that it can be kept in the balcony of the house. Stale food or wet waste is put in it. It converts the carbohydrates released by the microbes into methane gas, which is stored in the balloon. The methane gas stored in this balloon is piped to the biogas stove and you can use it as an alternative to LPG. Initially, Priyadarshan thought of organizing the waste from his house, but he felt that this waste could be used in some way, so he researched 'Vayu' to make it usable by the common man. According to an estimate, 931 million tons of food is wasted in the world every year and 570 million tons of food is wasted in households. If fuel is obtained from such food waste, then what is the special fuel called?

Priyadarshan Sahastrabuddha started this from his home and his society. Six to seven kg of wet waste per day is enough to make a household LPG free. Priyadarshan started enlisting the help of the city's sanitation workers to use the biogas device he had built on a large scale. Priyadarshan takes wet waste from the cleaning staff. In return, they give five hundred rupees per month to the cleaning staff. Today there are six to seven families in Pune who are using 'Vayu' and have got rid of LPG consumption by ordering wet waste from the cleaners. Priyadarshan says that if there are twenty families living in an apartment, two families can run their business with biogas from all their waste. They are trying to prevent wet waste from going to dumping sites and LPG. Dependence on can be reduced. Vayu is a biogas system in which microbes produce biogas, along with liquid fertilizer and organic fiber, which is useful in gardens. The best thing about Vayu is that it can be scaled up as needed. A small machine is made for twenty three thousand rupees and a large one for around one lakh rupees. US-based Ashoka Changemakers HSBC, an entrepreneur working on environmental protection. Award together. Out of 348 contestants in the world, twelve contestants were selected for the Green Skill Innovation Challenge, among those twelve contestants, Priyadarshan Sahasrabuddhe's 'Vayu' was selected. Priyadarshan is twenty five km from Pune. Far runs the 'Climate Cafe', the world's first LPG station. There is a free cafe. Here food is prepared only with biogas. If 2.1 tonnes of waste is collected daily, 2670 gas cylinders will be saved in a year and 115 tonnes of carbon dioxide will be reduced. They aim to collect two tonnes of waste per day in the next five years. 37-year-old Priyadarshan, who installed 320 wind turbines in the country, taught the common man that he can get energy from his food waste and the income of waste pickers increased tenfold. They clearly believe that using gas in homes, restaurants, corporation canteens, housing societies will save fuel, generate new employment and keep cities clean.

Success of 'Solar Lajja'

Dr. I live in Bai. Madhurita Gupta is a veterinary doctor and founder of the Wildlife Trust. For the last ten years he has been working for animals in zoos, wildlife safaris and national parks. During his work, when he happened to meet the women of the villages, Dr. Madhurita came to know that village and tribal women face many hardships during their periods every month. Some women even used sandbags. Dr. Madhurita Gupta started providing sanitary pads to solve this situation and help women, but this created another problem of its disposal. Even though only 36 percent of women in India use sanitary pads, it adds up to one lakh tons of pads. which is thrown in the garbage. According to Menstrual Health Alliance India, it takes about five hundred to eight hundred years for a sanitary pad to be disposed of, as it consists of non-biodegradable plastic and super absorbent polymer, so does not decompose easily and harms the environment. Dr. Madhurita expressed her concern to her brother Rupan Gupta. I.I.T. And Roopan, who studied at IIM, had a lot of knowledge about machinery because of his engineering studies. After many months of research, the siblings came up with a solar powered sanitary pad incinerator named 'Solar Lajja'. Which was started as a startup by Arnav Greentech Innovation in 2019.

Dr. Madhurita Gupta says that sanitary pads are an indispensable necessity for women. On the other hand it pollutes the environment. As a compromise, 'Solar Lajja' emerged. After nine months of research, Solar Lajja has been launched in the market. So many companies make sanitary pad incinerators, but they run on electricity. Even today there are many places in our country where electricity has not reached, so there was a desire to make a machine powered by solar energy. Which was realized with 'Solar Lajja'. Solar Lajja is eco-friendly and sustainable. Once it is installed there is no other cost. It is powered by the solar panel mounted on it. The solar panel is recharged by the heat of the sun. This machine can dispose of sanitary napkins as well as biomedical waste including tampons, diapers, masks and PPE kits. In a day, buses dispose of sanitary pads and convert them into ash. This ash is used as fertilizer in fields and gardens. Due to the lack of such arrangements in schools and colleges, sixty percent of the girls suffer which harms their health.

If sanitary pads are not disposed of properly, they pose a threat not only to landfills, but also to water bodies and animals. A 'Pad Dispatching' unit can also be installed along with the Solar Lajja. Today they provide sanitary pads to women in many villages and ensure that they do not use anything else. Solar Lajja works on automatic mode, in which it takes only a minute to dispose of the pad. Each unit of Solar Lajja saves forty-eight thousand watts of electricity, thus helping to reduce the carbon footprint as well. Under this startup started from 2019, Dr. Madhurita and her team have installed thirty-eight machines in eleven states of India. People are getting very good response. So far this machine has been installed in cities and villages of Maharashtra, Rajasthan, Uttar Pradesh, Uttarakhand. Working on a project with Sikkim Govt. The most important thing is that its basic unit price is forty three thousand and can be resized as per need. Madhurita has donated this machine to many places. Many women have got employment through this, last year it also earned twenty lakh rupees. The demand for this machine is increasing. Apart from India, orders have also been received from Germany, Sweden and Spain this year, but cannot take more orders as their manufacturing unit is small. He has received many awards for this unique innovation. In 2019, it was included in ten healthcare innovations in Singapore, while in 2020, Dr. Madhurita Gupta was included in the Top Ten Innovations by United Nations Women. Solar Lajja was also included in the top ten innovations by the Maharashtra State Innovation Society. He is happy that his innovation is helping the environment.
