New breed of entrepreneurs emerge in Telangana’s Covid fight

Telangana has a total of 45076 confirmed cases of SARS-COV-2 as of 19 July. As many as 12224 are active and under treatment.

The consistent rise in the number of COVID-19 cases in the community has now left everyone looking for ways to stop the virus from entering their homes.

A few days ago, Ganesh Babu, secretary of an apartment society near Hyderabad’s Indira Park, ensured all 185 flats in the society were disinfected and sanitized. This was just a precautionary measure but it has become a necessity in present times, he says.

“We had 15 positive cases of COVID-19 in our society. Four families were infected and quarantined at home. Though they have all recovered, we did not want to take a chance when we came to know about this,” says Babu, who himself is a senior citizen, adding that the work was professional.

Each and every house, as well as the exteriors and common areas, were disinfected by a professional team. Further, the society has also entered into a contract with them to get the premises sanitized every three days.

Twenty-nine-year-old Adke Pradeep Kumar, with his degree in MSc Biotech, calls himself one of the early entrants in the booming business of fumigation services in Hyderabad.

The consistent rise in the number of COVID-19 cases in the community has now left everyone looking for ways to stop the virus from entering their homes. Especially, as one is now advised to learn to live with the virus. With facemasks, hand sanitizers and physical distancing now part of the new normal, the fear of contracting the disease is prevalent. With this, new businesses have emerged. Mainly, that of sterilizing and disinfecting residences, office spaces and businesses.

Twenty-nine-year-old Adke Pradeep Kumar, with his degree in MSc Biotech, calls himself one of the early entrants in the booming business of fumigation services in Hyderabad. He along with his cousin Thotlapalepu Methuselah, and friend Vattepu Sabastian, started the business over a month ago and now boasts of a long list of clientele.Coronavirus Explained.

“There are people offering fumigation services using bleaching powder, but what we offer is three-layer sanitation. There is a huge demand. Initially, people used to call us just as a precaution but now with the rising number of COVID-19 cases, everyone is worried and wants to stay safe,” says Kumar.

His teams use sprinklers to spray sodium hypochlorite and ethanol-based sanitizers for exteriors, fogging machines to smoke interiors with sodium hypochlorite, and also use UV-sanitizer guns for all surfaces and common touchpoints inside the home. Currently, they have contracts with around 35 corporate offices, two franchisees of a leading international fast food joint, apart from several apartment societies in Hyderabad. They have already expanded their business to Khammam district, too.

“We started with three of us and now we have five regular teams with 20 members each. We can hire more workers if needed. It takes around 40 minutes to completely sanitize a house,” says 21-year-old Methuselah, who was waiting to go abroad for higher studies when the lockdown was imposed in March.

He says the intention was not to make money but to help prevent community transmission. They charge Re 1 per sqft for residential contracts and Rs 1.5 per sqft for commercial works. “We took guidance from several doctors and experts. Our service is a necessity today. It is not about making money,” he adds.

It was around the same time last month that Palwai Jason and wife Sirisha, both MSc Microbiologists by education, started their business of disinfection and sanitization. He teamed up with seven other professional Microbiologists from his known circle to offer pharma-grade sterilization. After testing waters by offering services to individual households, apartments, and corporate offices, Jason says he wants to focus on the sanitization of restaurants.

“As microbiologists, we are trained to keep every inch of our lab clean and hygienic. My experience of working in the pharma industry and knowledge from working in different virology labs has helped me gain a better understanding,” he says. It was when a friend asked him to help with sterilizing his restaurant, in the wake of COVID-19 situation, that he realized the potential in what he already knew.

Jason’s team is currently doing regular sanitization of three restaurants in the city. His team uses formaldehyde solution and glutaraldehyde solution for fumigation. Last month, he completed FSSAI training for food and restaurant management handling in the present COVID-19 situations. With this, he is offering services ranging from restaurant sterilization to food contamination analysis and biowaste management.

“With guidance from the CSIR-Central Food Technological Research Institute, he uses ethyl alcohol-based disinfectants for food-grade at the restaurants. We use UV static pass boxes (medical grade) for food and cutlery, and also recommend biodegradable tableware,” says Jason, who also works as a lab technician on a contractual basis for testing COVID-19 samples at one of the government medical colleges in the city. A weekly certificate of disinfection, sanitation, and quality management for a restaurant costs Rs 15,000. The process involves five to seven hours of work every night after regular restaurant work hours.

Noting that there is a spike in the number of buildings and apartment societies opting for a complete COVID-19 sanitization, Anand Kataria, a businessman and vendor of disinfectants, says that people just want to be on the safer side and are using all available options. “In my opinion, the effect of disinfection stays for not more than 24 hours, but people still want to get it done. There is a huge demand, especially, in buildings where a majority of residents are senior citizens.,” he pointed out.

Telangana has a total of 45076 confirmed cases of SARS-COV-2 as of 19 July. As many as 12224 are active and under treatment. Of them, 1900 are in different hospitals whereas the rest are in home isolation and care. At least 415 persons have succumbed to the disease.

Minister G Kishan Reddy inaugurates the ARC facility on Tuesday (Photo |EPS)

Hyderabad :

Astra Rafael Communication System, a joint venture between Astra Microwave and Israel-based Rafael Advanced Defence Systems Ltd, on Tuesday inaugurated a state-of-the-art facility to manufacture tactical communications system (BNET) for the Indian Armed Forces. 

Set up at an investment of `35 crore at the Hardware Technology Park near Shamshabad Airport, the ARC would be India’s first private sector company to manufacture communication systems in multiple variants. The joint venture will start with $30 million order for providing software-defined radios for the Indian Air Force (IAF), Rafael’s CEO Yoav Har-Even told reporters.

The production facility would be manufacturing radio models such as BNET-V (Vehicular) Broadband IP Radio, BNET-AR (Air) Broadband IP Radio, BNET-MPS (Man-Pack System) Broadband Radio, BNET-HH (Handheld) Broadband Radio and C4I Connect —a secured tactical network.

Gurunatha Reddy, MD of Astra Microwave Products Ltd, said that as of now the joint venture would concentrate on manufacturing, but later would graduate towards design and development of equipment for defence communication. “We will also get into electronic warfare and signal intelligent systems as we go forward,” he added.

Meanwhile, Union Minister of State for Home G Kishan Reddy, who was the chief guest at the event, pointed out that the Centre has taken numerous steps to boost indigenous production as part of Make in India. He also said that the FDI was being encouraged in railways and defence. 

Also present at the inauguration was IT and Industries secretary Jayesh Ranjan, who hoped that Israeli companies would invest not only for manufacturing joint ventures but also in design JVs. “Just as Hyderabad is becoming the defence and aerospace capital of the country, we would like to play a significant role in the design ecosystem also. If we could get Rafael and other Israeli players in Hyderabad we would support it,” he said.

Now, an oral drug to treat deadly kala-azar — IIT Hyderabad says it’s faster, better

Researchers at IIT Hyderabad say the pills will ensure controlled release of the drug used to treat the disease, bettering a patient’s chance of survival.

New Delhi: 

Researchers at the premier Indian Institute of Technology, Hyderabad, have formulated oral tablets that they say will ensure better and faster treatment of the deadly parasitic disease visceral leishmaniasis, commonly known as kala-azar or black fever.

Kala-azar is a fatal disease caused by the bite of a sandfly; it affects the bone marrow, spleen and liver. At present, the disease is treated through injection-based administration of the drug Amphotericin B but that leads to an uncontrolled release of the drug into a patient’s bloodstream, resulting in high toxicity.

The IIT researchers say their tablets will release Amphotericin B in a sustained and controlled manner over a period of 10 days, which is likely to increase the chances of a patient’s recovery.

The drug uses nanofibres, which are 1,00,000 times thinner than human hair, for the controlled release of drug molecules.

“In order to make controlled-release oral tablets, the drug molecules must be loaded onto a base that dissolves gradually to release the drug over a period of time,” said Dr Chandra Shekhar Sharma, associate professor, creative and advanced research based on nanomaterials (CARBON) laboratory, Department of Chemical Engineering, IIT Hyderabad. Sharma led the research along with professor Saptarshi Majumdar.

“The development of oral, controlled-release tablets for fatal fungal infections and leishmaniasis, will help in better management of the disease burden in the country,” IIT Hyderabad said in a statement Thursday, adding that “the team’s work has been published in the July 2019 issue of the reputed peer-reviewed journal Nano-Structures and Nano-Objects”.

“Many attempts have been made earlier to make oral medication to control the delivery of the drug and bring down costs,” the statement added.

Status of kala-azar in India

In India, malaria, dengue and kala-azar are the top three vector-borne diseases.

According to the latest data by the Ministry of Health and Family Welfare, India registered over 5,700 cases of kala-azar in 2017.

Often referred to as a ‘disease of poverty’, the maximum number of cases were found in the economically underprivileged sections of Jharkhand, Bihar, West Bengal and Uttar Pradesh.

India had missed the 2017 deadline set to eliminate the disease. This was blamed on the absence of concrete or pucca houses in most infected areas and the issue was raised with the rural development ministry.

“As the endemic blocks (states) have a majority of houses made of wood, it is very difficult to eliminate the vector as it (the parasite) dwells in the wooden structure and escapes various measures to kill it,” reported  The Financial Express last year. “Hence, to stop the transmission of infection, pucca houses need to be built.”

IIT-Hyderabad researchers develop method to make biofuel with sugar and salt

The researchers described the novel process that can produce carbon catalysts at room temperatures using sugar, sulphuric acid and salt in the journal ‘ACS Sustainable Chemistry and Engineering’.

Hyderabad : 

Researchers  at IIT Hyderabad have developed a simple and innovative method to synthesise a catalyst that can convert chemicals derived from biomass into a precursor to diesel and jet fuel, the institute said on Tuesday. This catalyst showed better efficiency and selectivity than commercial catalysts to produce C15 oxygenated hydrocarbon, a biofuel precursor.

The researchers described the novel process that can produce carbon catalysts at room temperatures using sugar, sulphuric acid and salt in the journal ‘ACS Sustainable Chemistry and Engineering’. “The dehydration of sugar by concentrated sulfuric acid is high-school chemistry. But the intense heat released is not well-controlled,” explained Dr Atul Suresh Deshpande, assistant professor at IIT-H.

In order to control the exothermic dehydration of sugar, the researchers add common salt. Salt helps in controlled dehydration of sugar, which leads to formation of the desired carbon nanoplates. “Due to the low cost of precursors with practically zero energy input and simplicity of reaction, this process of producing carbon nanoplates can be easily adapted for large-scale commercial production,” added Prof Sunil Kumar Maity.

This development is important for States such as Uttar Pradesh and the two Telugu states which are the largest producers of corn in India. The large amount of corncob waste can now be converted into fuels and allow additional income for farmers of corn, provide a sustainable energy source and reduce carbon footprint in the automobile/ aviation sector.

Hyderabad-based couple recycle plastic waste into bus shelters and kiosks

A snapshot of the kiosks for street vendors in Sircilla. Each 8X8ft kiosk is designed by recycling plastic waste   | Photo Credit:  By arrangement

In the last week of June, eight kiosks were inaugurated for street vendors in Sircilla, in a bid to have segregated areas for vendors and ease traffic congestion. Soon, a total of 55 kiosks will come up in different pockets of the town. Each of these kiosks of 8X8 square feet area have been built with boards manufactured by using recycled plastic. Nearly 22,000 kilograms of recycled plastic (roughly 88 lakh milk packets) go into making these kiosks. Soon, Siddipet will also have 45 such kiosks.

The force behind this project is the Hyderabad-based entrepreneur couple Prashant Lingam and his wife Aruna. The duo has a decade-long experience in designing bamboo furniture and housing, after which they tried their hands at upcycled furniture made from old rubber tyres, bottles and drums.

The parking shelter near Miyapur metro station, Hyderabad, is constructed using boards made by recycling plastic waste 

Their compact office in Swaroop Nagar, Uppal, gives visitors an idea of their work. One part of the office has bamboo furniture and décor, while the other part uses chairs and a table made from recycled plastic. An eight by four table has an 18millimetre thick board made by recycling  used milk packets. “The boards have been made using 70% LDPE (low density polyethlene) such as milk packets, and 30% aluminium-coated LDPE sheets,” Prashant explains. The wall panels are also made from recycled plastic and mounted on metallic frames. The couple emphasise that these boards are acid and fireproof.

Recycle, reuse Number of kiosks: 55 in Sircilla, 45 in Siddipet

  • Kiosks are built with boards manufactured from recycled plastic.
  • Nearly 22,000 kilograms of plastic waste (roughly 88 lakh milk packet covers) go into making these kiosks.
  • The paved pathway in Hyderabad Dog Park and the parking shelter near Miyapur Metro station have been built using recycled plastic.
  • Coming up: A bus shelter made with recycled plastic at Kavidiguda, opposite the National Thermal Power Corporation office.

Their upcycled rubber and bamboo furniture caught the attention of GHMC (Greater Hyderabad  Municipal Corporation) in 2013. It was also the time when Prashant and Aruna were looking to do something new, within the ambit of being environment-friendly. They designed bus shelters, near Shilparamam and Swaroop Nagar, where the metal-framed structure had slots for discarded plastic bottles. It was a starting point and Prashant got thinking on how to recycle plastic waste. “We researched for a year, met experts, and looked for industrial solutions. We are now collaborating with a factory in Gujarat to manufacture these boards,” he says.

The segregated single use and multi-layer plastics are shipped to a factory in Gujarat to manufacture the boards, which are then sent back to Hyderabad. While this idea of recycling can be a big win to address the growing plastic menace, a problem the team faces is with sourcing the waste, since most homes and offices don’t segregate waste.

Prashant’s initiative makes two kinds of recycled boards — one from single use plastic waste (straws and covers of chips packets, for instance) and another that uses multi-layered plastic (MLP). The boards made from single use plastics have been used to design a shelter for parking near Miyapur metro station. “If homes and offices diligently segregate their waste, our work will become easier and we will also be addressing the issue of plastic ending up in landfills,” says Aruna, who wants to start an awareness campaign in schools on waste segregation.

Aruna and Prashant Lingam in their office, decked with furniture made of recycled plastic waste  

The Miyapur parking shelter got attention and there were enquiries from international firms who wanted to buy the technology. Prashant and Aruna turned it down: “We started this work to find a solution to our plastic waste, rather than sell the technology and enable international firms to recycle their plastic and export them to India,” they emphasise.

The couple has also used milk packets to design interlocking pavement blocks for the Dog Park in Hyderabad. Each block has used 600 milk packets, and the interlocked paved path extends to 3500 square feet.

Prashant and Aruna mention that the district authorities in Hyderabad, especially the GHMC West Zone Commissioner Hari Chandana Dasari, and authorities in Sircilla and Siddipet districts have supported all their endeavours of recycling plastic waste.

There are further plans. A bus shelter using recycled plastic is coming up in Kavadiguda area, opposite the National Thermal Power Corporation (NTPC) office. The 24X8 bus shelter is a CSR initiative of NTPC. The couple will also be collaborating with UNDP (United National Development Programme) to design bus and parking shelters, and kiosks from recycled plastic for different locations in Hyderabad.
