Proper biomedical waste (BMW) management in accordance to the stipulated rule was
one of the neglected aspects of health care for years, especially in developing countries
like India. Since the BMW Management Rules, 2016 by Government of India (GoI), Ministry
of Environment, Forest, and Climate Change initiated changes by prescribing simplified
categories (color coded) for segregation of different BMWs, an amendment in 2018 also
came into force with the aim to improve the compliance to the rules.[1]
[2] Nonetheless, proper segregation, handling, and disposal remained a serious concern
for health care facilities across India with an annual growth rate of 7% with a projected
estimate up to 775.5 tonnes/d by the year 2022.[3]
Amidst the coronavirus disease 2019 (COVID-19) pandemic, the scenario might worsen
as evidenced by some initial experiences, with piles of personal protective equipment
(PPE) accumulating in the hospitals ([Fig. 1]). In spite of the guidelines by World Health Organization and Ministry of Health
and Family Welfare, GoI regarding the rational use of PPE for COVID-19, health care
settings are experiencing high demand of PPE from all strata of health care workers
owing to the fear of infection.[4]
[5] The apprehension is often resulting in the misuse of PPE on many occasions aggravating
the problem by generating huge quantity of BMWs which are difficult to store and transport
with limited resources and manpower available at the time of crisis. Added to the
menace, is the indiscriminate use and disposal of single-use surgical masks (at times
N95 respirators) even in the community. Their disposal is often being carried on along
with the noninfectious kitchen/general waste from the household and residential areas
where color-coded BMW bins are difficult to be found. It is worth mentioning that
for the new severe acute respiratory syndrome coronavirus 2 (SARS CoV2) with fomite-borne
transmission and yet to be known period of viability on the fomites, the indiscriminate
disposal of BMWs in the general garbage provides an easy access to the largely susceptible
community.[6]

In response to the COVID-19 pandemic in India, Central Pollution Control Board (CPCB),
Ministry of Environment, Forest & Climate has published guidelines for the management
of waste generated during treatment/diagnosis/quarantine of COVID-19 patients.[7] These guidelines have advocated use of double layered bags (using two bags), mandatory
labeling of bags and containers as “COVID-19 waste,” regular disinfection of dedicated
trolleys, separate record keeping of waste generated from COVID-19 isolation wards,
in addition to the recommendation for following existing practices of BMW Management
Rules, 2016. Although the CPCB is the nodal agency for making any recommendation pertaining
to BMW in India, some guidelines have also been published by other government agencies
for the management of COVID-19 waste. While the latter guidelines must conform with
the recommendations made by CPCB, disparities have been noted in some with respect
to the segregation norms of existing BMW Management Rules, 2016 in which the segregation
of the items is devised based on the final mode of treatment. This abrupt change in
the category of certain BMWs might result in inappropriate final treatment.
Addition of spill management from the BMW bags or containers, recommendation of ideal
PPE for persons handling BMW, provision of health check-up for those individuals may
be considered in the upcoming guidelines by CPCB. Other government agencies should
clearly state in their own guidelines that the norms laid by CPCB should be followed
for BMW management with mention of the specific URL of the CPCB guidelines. Besides
maintaining uniformity in the guidelines, the monitoring of implementation of the
prescribed policies for BMW management should also be prioritized. Hospitals and institutions
should expand their capacities to transport and store BMWs owing to increase in the
quantity of the waste. An electronic communication mechanism should be in place to
specify the exact quantity of “COVID-19 waste” in different categories, any breach
during transportation and treatment which should be notified to the nodal agency.
Institutional infection prevention and control team should conduct regular training
of all concerned staffs for BMW management and monitor the practices. These steps
in combination with strict adherence to the norms will ensure better handling of the
impending crisis.
As is evident from the current situation of the pandemic, basic infection control
practices are the only measures for containment. Proper waste disposal is an integral
part of these control measures. Through this letter, the authors intend to draw the
attention of the concerned authorities at the institutional and local administrative
levels for thorough implementation of the prescribed policies with the scope of overall
improvement in the BMW segregation and disposal in daily practice which will be of
immense help even after the pandemic.
