ABSTRACT
The global outbreak of coronavirus has affected all the aspects of human lives. In order to control the spread it was recommended to avoid social contact with each other and so most of the affected countries imposed lockdown. During lockdown, major anthropogenic activities were put on hold that resulted in decrease in pollution level. The improvement in air quality, water quality and noise levels were due to restriction on various pollution sources like vehicles, factories, mining etc. There were certain adverse effects on environment amid Covid-19 due to more solid waste production and medical waste. The chapter gives an insight into the qualitative and quantitative effect of lockdown amid covid-19 on the quality of air and water in different parts of the world. © 2022 Elsevier Inc.

ABSTRACT
Covid-19 [Corona virus diseases] has emerged as one of the most critical global disaster over the last few years. Numerous research are going on to ascertain the various dynamics of evolution and spread of the disease. There are evidences that bats were host of similar kind of viruses, previously. The remarkable resemblance of the RNA of the SARS-CoV-2 virus with the RNA of bat coronavirus. The chief mode of transmission of the virus is droplets form an infected patient via cough, sneezing or talking. Different measures were taken to control the spread of the virus including lockdown in the various parts of the affected countries. Few medications also helped to treat the infected patients. However, trials of vaccinations are still in progress. The pandemic has affected all aspects of life be it social, economical, health or environment. © 2022 Elsevier Inc. All rights reserved.
ABSTRACT
Covid 19 is a highly infectious disease caused by SARS-CoV-2 that can spread from an infected person’s nose, mouth during coughing & sneezing. One of the warriors against Covid-19 is personal protection equipment (PPE), which is indispensable for everyone working closely with Covid-19 patients. The kits are made of different types of plastics and their disposal is going to be a serious menace, if not taken care of properly. The sustainable alternative to handle cast-off PPE kit is to convert them into pyrolysis oil using a thermochemical process. In the present paper, pyrolysis of PPE kit is done in a lab scale reactor to get the pyrolysis oil that has the potential to be used as alternate fuel in the neat or in blended form with conventional fuels. GC-MS of the obtained oil shows the presence of (C-7 to C-32) hydrocarbon fraction. FTIR analysis of the oil is also done for functional group composition. The results obtained also support the application of pyrolyisis oil as an alternate fuel. Physico-chemical characteristics of the pyrolysis oil sample are also comparable to the commercially available fuel with exception of viscosity as the fuel obtained has not been fractionated and has both light and heavy naphtha. © 2022 Informa UK Limited, trading as Taylor & Francis Group.
