COVID 19: Another Threatening to Waste Management

By Suman Nandy
Caparica, Portugal.

2020, we are experiencing an unwanted situation that has changed our entire lifestyle. The whole world (more than 213 countries and territories) is affected, impacting all social areas and sectors, reaching from, health to economy.We are habituated with three phrases: “keep safe distance”, “wear your mask” and “sanitize yourself”. Because of the highly contagious parameters, we are concerned about the single use products such as personal protective kit, gloves, face mask and packaging. Right now, health and safety have taken priority over the environment. But this should not be a well practise for sustainable future. A civilization can only exist with their future thoughts.We can live better now, but we must think best for tomorrow.Coronavirus disease 2019 (COVID-19) situation is alarming us, to be careful and prepare for future. We are still not smart that we assume! There is no denying that already the world is in crisis due to overuse of un-recycled product that will end up in landfills and sustain over 100-1000 years. These kinds of unrecycled and unreacted products are affecting the soil, sea and river water that makes a negative effect in environment and living plants and animals. It was reported by European Union that in the Europe, 31kg of plastic packaging waste is produced per person per year in average that adds up to 15.8 million tonnes of plastic packaging waste generated in one year1.Waste plastics are a serious and growing environmental problem. In 2015, the Sustainable Development Goals (SDS) that are set by United Nation to achieve a better and more sustainable future for all by 2030, sustainability, waste management, recycling of product and environment are the concerning factors2.

But the present situation due to COVID-19 pandemic has led to a serious impedimentin waste management progress. Proper management of safety procedure will protect us in this crucial situation of pandemic. But mismanagement and misuse can also lead to another big crisis in environmental pollution. On 1st July 2020, the World Economic Forum reported an article entitled “The plastic pandemic is only getting worse during COVID-19”3. It raises the question of single-use plastics during the pandemic. Mostly, all the countries are facing mismanagement in waste product control. According to the report4,5 in China, medical waste from personal protective equipment like gloves, face masks and eye protection due to a surge in pandemic has raised tremendously from 40 tons per day in normal days to a peak of 247 tonswhich is about six fold.According to the Waste Agency of Catalonia report, the medical waste including masks, gloves, overalls, or davantals, has detected a 350% increment since mid-March which ismostly 925 tonnes more than usual6. According to the Thailand Environment Institute (TEI), plastic waste has increased from 1,500 tons to 6,300 tons per day, due to the frequent owing of home deliveries of food in pandemic situation which is 15%. TEI president Dr.Wijarn said, in Thailand each day, approximately 1.5 million face masks are being used and disposed. In Bangkok, the amount is about 150 tons per day7. With a same trend, in United Kingdom, there has been reported a huge spike in fly-tipping (illegal dumping) in some parts during the coronavirus lockdown.The Countryside Alliance reports approximately of 300% rise in fly-tipping after local authorities closed recycling centres amid the Covid-19 crisis8. Moreover, along with the increment of medical and protective kit wastage, COVID-19 pandemic situation also makes an obstruction on normal waste disposal and recycling system. According to the survey (on 18th May 2020from 95 surveyed communities) by AMORCE (French network for information, sharing of experiences and support for local authorities in the field of energy transition, territorial waste management and water cycle management), 42% of communities have noted a tendency to deposit non-conforming waste in the bins (mixed-waste or separate collections) and 48% noted an upsurge of illegal deposits. Also, an interruption has been noticed for selective waste (such as glass, paper, food waste, bulky waste) collections (door-to-door or bring-banks). Bulky waste and textile collections are the most interrupted which is about 41% 9. This situation is more or less similar in all over the world.

Therefore, specific plans and awareness programs should be carried out by all the countries and associations so that our fight against waste management and environment pollution will come in required track. People should be alerted to maintain selective waste management system. Also, we have to think about the use of biodegradable natural materials which will not make a negative impact on environment.

The pandemic named COVID 19: India beyond 2020

Dielectica traverses through the literature on this novel piece of protein coated RNA – and summarizes as they appear.

Correspondence prepared by: Sayan Dey (21st July, 2020 08:30 IST)

KOLKATA: When the whole world is fighting a novel virus with debatable origin called COVID 19, India is climbing the league table steadily in terms of affected population and deaths. As of 8th August, 2020, India bagged the highest spot with over 65,000 new cases of infection. These are tough days when we are losing over hundreds of our fellow countrymen every day; the count has crossed the thousand mark on the ninth day of this month. It seems as if death is taking its turn in the most drastic way. Complete lockdowns, community spreading, quarantines have become very common for us nowadays. Sometimes by July 2021, we would be well accustomed to these occasional lockdowns and lose even more touch with one another in terms of social distancing. Half of us would lose our jobs and who can say, we may have some new business giants rising out of the pharmaceuticals. Wearing masks would be a fashion by then and traditional Dusserra, Diwali and Lori would completely lose their importance. According to a prediction by two professors from the Massachusetts Institute of Technology Hazhir Rahmandad and John Sterman and their group, India may pose the worst possible scenario by winter 2021, if proper vaccination is not available as the daily case counts may reach upto 2.87 lakhs. Under this dark circumstance, research Technology Kharagpur developed a new technology for low cost and portable COVID test kits. “This first-of-its-kind device will bring the testing for COVID-19 out from the walls of expensive laboratories and RT-PCR machines and enable testing at affordable costs for the under-served community across the world,” a press statement from IIT- KGP said.Prof. Suman Chakraborty said, “The technology developed is very much different from traditional detection systems used across the world. This method has eliminated the need for a PCR machine. It includes a portable, automated

organisations throughout the country have developed several rapid diagnostic kits.

On 10th May, National Institute of Virology (NIV), Pune successfully developed India’s first indigenous ELISA (Enzyme linked Immunosorbent Assay)based test kit for SARS – CoV-2 antibody detection. The union health minister Dr. Harsh Vardhan said, “The robust indigenous IgG ELISA test for antibody detection developed by ICMR-NIV, Pune will play a critical role in surveillance of proportion of the population exposed to SARS-CoV-2 coronavirus Infection.” The ICMR partnered with Zydus Cadila to market the kit in the early stages of the pandemic.                 With time and increasing severity, Indian Institute of Technology, Delhi came up with the cheapest rapid detection kit named “Corosure”. The kit was approved by the ICMR and Drug Control General of India and was produced in large scale by NewTech medical devices could be made available at an alarmingly low price of Rs. 399 (i.e. $5.32 per kit). This Real Time – PCR unit facilitated a pre-programmable temperature control unit, a special detection unit on genomic analysis and customised smartphone application for test results without any manual interaction”. He also added that RT-PCR based tests suffer from a compelling constraint of requiring an elaborate laboratory-infrastructure and support system including the operational and maintenance cost, to perform the test. The equipment will cost approximately Rs. 2000 (i.e. $26.66) and will revolutionize the diagnosis science throughout the world. The director of IIT Kharagpur Prof. V.K. Tewari expressed

probe free, high accuracy diagnosis with minimum false positives. Mr. Jatin Goyal, founder of NewTech medical devices in a press meet on 15th July said, “unique technology developed by IIT Delhi and our expertise in reagent and kit-making, we have ensured an accurate, affordable, Make-in-India kit for the diagnosis of SARS-CoV2, which is a ‘probe-free’ method, and reduces the testing cost without compromising on accuracy. We are anticipating two million kits by next month”.The HRD minister Mr. Ramesh Pokhriyal while launching the affordable kit commented, “The country requires affordable and reliable testing which can help to control the pandemic. The Corosure has been developed indigenously and is much cheaper than other kits. The kit has received ICMR approval with the highest score and DCGI approval with a very high sensitivity and specificity”.According to the Director of IIT Delhi, Prof. V. Ramgopal Rao, the institute and its researchers would be dedicatedly involved in the COVID-19 research until the country along with the rest of the world frees itself from its clutches completely.                 Developments by the Indian scientists are progressing fast. With a far sighted vision of beyond 2020, when a kit will be indispensable in practically every house, the scientists from the Indian Institute of

the hope that the innovation “can make significant breakthrough in global viral pandemic management” and added that the unique innovation is aligned with the institution’s vision to “develop high-end healthcare technologies that can be afforded by the common people”.                 So, it seems that India has prepared herself well to go beyond the darkness of 2020 hoping to strive in light with expectation of the clouds of corona getting wiped out of the face of the earth by 2021 end.
