Accordingly, to address this problem, the United Nations Environment Program (UNEP) will hold a conference on single-use plastic products pollution with a life cycle approach on  Feb 19, 2021.  

Waste Management during the COVID-19 Pandemic From Response to Recovery
In a report titled “Waste Management during the COVID-19 Pandemic From Response to Recovery”  UNEP provides practical information, suggestions, and guidelines on Healthcare Waste Management  and Municipal Solid Waste Management  given the restrictions and limitations imposed by the ongoing pandemic. 

“We hope that this publication, with its combined ‘desk review’ of international guidelines alongside country level ‘facts on the ground’ survey responses, will provide some guidance and practices for municipalities, particularly in developing countries, as they deal with urgent concerns, and building more resilient cities for tomorrow” explained  Mr. Keith Alverson Director UNEP-IETC.  Because the “COVID-19 has had a serious impact on all parts of our society, and waste management is no exception. Waste management in developing countries is usually not operated in accordance with international standards, and so there have been additional difficulties with an increased amount of potentially infected waste which requires additional, careful handling and treatment processes” added Mr. Kazunobu Onogawa, Director, IGES Centre Collaborating with UNEP on Environmental Technologies.

Case Study Sri Lanka 
The UNEP study found that the Government of Sri Lanka formulated an Interim guideline for management of solid waste generated by households and places under self-quarantine due to COVID-19 outbreak in March 2020, for local authorities in Sri Lanka.  

During March 4 -5 Srilanka’s International Institute of Knowledge Management will hold an International Waste Management Conference.   

Case Study Brazil
According to another study to assess environmental impacts caused by shifts on solid waste production and management due to the COVID-19 pandemic in Brazil, 30 cities, representing a population of more than 53.8 million people (25.4% of the Brazilian population) was evaluated. Unexpectedly, the study found that solid waste production in the main cities in Brazil decreased during the social isolation period, possibly because of reduced activity in commercial areas but that more than 35% of medical waste had not been treated properly. Furthermore, improper disposal of facemasks was reported in several cities which may have increased the risk for COVID-19 spread. 

Global Case Study on Air Quality and Waste
Another study explored the overall positive and negative environmental impacts of the global COVID-19 pandemic. The study found that, the pandemic lockdown significantly improved air quality in different cities across the world, by reducing GHGs emission, lessening water pollution and noise, and reducing the pressure on the tourist destinations, which assisted with the restoration of the ecological systems.  Some negative consequences of the pandemic the study pointed out were increased medical waste, haphazard use and disposal of disinfectants, mask, and gloves; and burden of untreated wastes continuously endangering the environment.
