"இதில் ஒன்றும் பெரிய சூட்சமம் இல்லை," என கூறும் சுரேஷ், கடந்த 9 ஆண்டுகளாக சமையலறை கழிவுகளிலிருந்து அவர்களுக்கான சமையல் எரிவாயுவை தயாரிக்கிறார். இது எந்தவொரு ஆய்வகத்தில் தயாரிக்கப்படுவதில்லை, தன் சொந்த வீட்டிலேயே அவர் நிறுவியுள்ள உயிர்வாயு அமைப்பு மூலம் பெறுகிறார். சமையல் எரிவாயுவை உருவாக்குவதைத் தவிர, உயிர்வாயு வெளியிடும் மிச்சம் தாவரங்களுக்கு கரிம உரமாக பயன்படுத்தலாம். பல வருடங்களாக மேற்கூரை சோலார் பேனல் வைத்திருக்கும் இவரிடம் பலர் இது குறித்து ஆலோசனை கேட்டுச் செல்கின்றனர்.

Disposing of pet poop/pet waste is one of the most sensitive issues in a neighbourhood or apartment community, and there has been an increasing pressure on pet parents to be responsible by picking up after their pet. While one of the easiest solutions to dispose of pet waste is by bagging it, imagine the amount of plastic (fossil-fuel-based or plant-based) tied with dog poop that will be sent to landfills or incinerators.  An internet search around disposing pet waste throws up multiple options:  Bag it and disposeScoop and flush itScoop and trash near plantsScoop and bury, which basically promotes composting Let's…

The first doctor to report the Omicron variant on November 18th, 2021 was Dr Angelique Coetzee, National Chairperson of South African Medical Association. “On that day, I saw seven patients with similar symptoms of myalgia, headache, fatigue who tested positive for COVID-19 with rapid tests at my consulting rooms,” Dr Coetzee said in an email interview with Citizen Matters. “Their symptoms were different from Delta and I alerted the South African Ministerial Advisory Committee on Vaccines of which I am a part. It took our scientists six days to announce to the world that there’s a new variant.”  Subsequently, on…

78-year-old D Suresh lives with his wife, son and daughter-in-law in Kilpauk, and he says he has bought only two LPG cylinders per year since 2012. His family does not eat outside every day, nor do they use electric or induction stoves for cooking their daily meals. "It is not rocket science," says the septuagenarian when he says that he has been generating his own cooking gas from kitchen waste for over nine years. When the waste decomposes in the absence of oxygen, Suresh gets biogas that he uses for cooking. This process does not happen in a scientific laboratory…

Despite the dangers they pose to life and limb, Indians have learned to live with the potholes that abound in most roads in every city. According to the Ministry of Road Transport and Highways, potholes accounted for 3,564 road accidents in 2020, though the the exact number of deaths from these accidents is not known. But despite these appalling numbers, there is a complete lack of explicit or specific legislation dealing with accountability for deaths or injuries caused by potholes that are the result of poor quality work and lack of maintenance by the municipal authorities concerned. Can government or…

Policy making on public health issues requires data of many kinds. One such important data category is the number of birth and death registrations. For instance, the changes in birth registration allowed researchers to note the drastic drop in Karnataka’s fertility rate over the past 40 years. On the other hand, death registration has played a key role in identifying health trends in the state, especially during the COVID-19 pandemic. For citizens, birth and death certificates impact everything from admission into schools to entitlements like pension and other benefits. But what are the steps for registering and receiving birth/death certificates…

According to reports in media, the average footfall on Chennai Metro Rail crossed the one lakh mark in December 2021 and on December 30th, as commuters in the city found road traffic coming to a standstill in the face of unseasonal torrential rain, 1.83 lakh passengers used the Metro on the single day to reach their destinations. While the figures may have made news, it's clearly not enough to put authorities at ease. For, according to a report by the International Association of Public Transport (UITP), if the Chennai Metro Rail Ltd were to break even, it would have to…

A population census is still far away. But the Brihanmumbai Municipal Corporation (BMC) plans to do a dog census in Mumbai in March 2022. For a start, the BMC is doing an awareness drive towards responsible pet ownership in Mumbai by getting owners to license their pets. “As part of this campaign, BMC officials visited housing societies to create awareness and register more pet licences,” said Dr K.A. Pathan, general manager of BMC’s veterinary health department. “Since the process is entirely online and can be done over a mobile phone, our staffers would register the pets on the spot, and…

On January 6th, the state of Tamil Nadu recorded a total of 6,983 new positive cases of COVID-19. Out of these, 3,759 cases, which is around 54%, were recorded in the state capital of Chennai, which has been contributing to the most number of COVID cases in the state, followed by the districts of Chengalpattu and Coimbatore. Expectedly, people are now questioning whether we are now in the middle of the third COVID wave that the city had been fearing. Just about a month ago, on December 6 2021, Chennai recorded just 128 new positive cases, with the total number of…

2022 was expected to be a year of hope. A year when the COVID pandemic that had killed millions and wrecked economies around the world, would come to an end. But then arrived Omicron, a heavily mutated new variant. First detected in South Africa in November, it triggered a new wave of COVID-19 in Africa, Europe, and America. And in India, as the new year dawned, cities like Mumbai, Chennai, Calcutta, Bengaluru, and Delhi started seeing ever-increasing single-day spikes in COVID cases in nearly seven months. There were also wide variations in Test Positivity Rates (TPR) across the country likely caused…
