India generated over 18,000 tonnes COVID-19 waste since June; Maharashtra biggest contributor

COVID-19 biomedical waste could include PPE kits, masks, shoe covers, gloves, human tissues, items contaminated with blood, body fluids like dressings, plaster casts, cotton swabs, beddings contaminated with blood or body fluid, blood bags, needles, syringes etc.

India generated 18,006 tonnes of COVID-19 biomedical waste in the last four months, with Maharashtra contributing the maximum (3,587 tonnes) to it, according to a Central Pollution Control Board (CPCB) data.

Around 5,500 tonnes of COVID-19 waste was generated across the country in September - the maximum for a month so far.

According to the data received from state pollution control boards, since June, all states and Union Territories have generated 18,006 tonnes of COVID-19-related biomedical waste which is being collected, treated and disposed of by 198 common biomedical waste treatment facilities (CBWTFs).

COVID-19 biomedical waste could include PPE kits, masks, shoe covers, gloves, human tissues, items contaminated with blood, body fluids like dressings, plaster casts, cotton swabs, beddings contaminated with blood or body fluid, blood bags, needles, syringes etc.

According to the data, Maharashtra generated 3,587 tonnes of COVID-19 waste in four months since June, followed by Tamil Nadu (1,737 tonnes), Gujarat (1,638 tonnes), Kerala (1,516 tonnes), Uttar Pradesh (1,432 tonnes), Delhi (1,400 tonnes), Karnataka (1,380 tonnes) and West Bengal (1,000 tonnes).

COVID-19 Vaccine

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
