Lockdowns in many countries have resulted in the reduction of harmful emissions. Not only this in China alone, but there is also a 25 percent reduction in carbon emissions and a 50 per cent reduction in nitrogen oxide emissions. Infact, some studies suggest that because of the Covid-19 outbreak, air pollution has drastically dropped. Moreover, on the positive note, industrial and commercial waste production has drastically reduced because of the slowdown in manufacturing activities.
However, the environmental industry is also seeing the negative impact of coronavirus. When doing a historical comparison, the volume of medical waste has gone up by up to 40 per cent. Further, the higher production from the pharmaceutical and medical sectors have resulted in an increase in hazardous waste production. Moreover, owing to insufficient hazardous waste treatment capacity, many countries are facing the problem of stockpiling and potentially inadequate disposal.
Besides, there is also an increase in the volume of municipal waste. This is again followed by inefficient waste collection and disposal systems. Furthermore, there is a reduction in the recycling activities which is creating a challenge in the collection and disposal of municipal waste.
