“…Figure 1. Composition of Solid Waste Medical Waste from Vaccination Activities Ash from burning medical waste frequently contains heavy metals such as Pb, Zn, Cd, and Fe (22,(25)(26)(27) . Accordingly, the total combustion product of 8005.7-tons must be stabilized/solidified (S/S) to bind the toxic properties of the combustion ash.…”

Latar belakang: Indonesia, negara terpadat keempat di dunia, muncul sebagai episentrum Covid-19 di Asia pada pertengahan tahun 2021. Lonjakan kasus COVID19 mendorong negara untuk menargetkan 1 juta vaksinasi Covid-19 per hari.Metode: Penelitian ini menggunakan data kualitatif dari tinjauan pustaka sebelumnya kemudian diolah menggunakan perhitungan yang sesuai dengan metode pengelolaan limbah vaksin.Hasil: Meskipun peluncuran vaksinasi besar-besaran, dampaknya terhadap lingkungan masih dipertanyakan. Tidak hanya pembuangan limbah medis yang tidak tepat tetap menjadi tantangan sejak wabah pandemi pada tahun 2020, tetapi vaksinasi memperburuk keadaan. Selain limbah padat, konsumsi listrik dan emisi polutan dari zat pendingin mungkin berkontribusi terhadap jejak karbon yang tinggi.Simpulan: Makalah ini menyoroti pentingnya pengelolaan limbah selama Covid-19 dan konsekuensi tak terduga pada penyimpanan dan penanganan vaksin untuk pengambilan keputusan peluncuran vaksinasi lebih lanjut. ABSTRACT Background: Indonesia, the world’s fourth most populous country, emerged as Asia's Covid-19 epicenters in the mid of 2021. The surge in COVID19 cases drives the nation to aim for 1 million Covid-19 vaccinations per day. Method: This study uses qualitatively and quantitatively data from previous literature reviews and then processed using calculations that are in accordance with the vaccine waste management method.Result: Despite massive vaccination rollout, the impact on the environment is still in question. Not only has improper medical waste disposal remained a challenge since the pandemic breakout in 2020, but the vaccination worsened the circumstances. In addition to solid waste, the electricity consumption and pollutant emissions of the refrigerants might contribute to a high carbon footprint. Conclusion: This paper highlights the importance of waste management during Covid-19 and unforeseen consequences on vaccine storage and handling for decision making of further vaccination rollouts.

“…In many developing countries, including Pakistan, incinerators consist of primary and secondary combustion chambers for treatment of medical wastes [ 14 ], while the WHO recommended standard is a multi-chambered incinerator. In these incinerators, an absorption combination wet cyclone ensures the removal of gaseous particles, [ 15 ] whereas other low weighted air particles are preferably removed by lowering the temperature up to 200 °C [ 16 ]. In general, these incinerators work on high temperature and gas retention time frames and therefore require a huge quantity of fossil fuels to reach the desired temperature in their combustion chambers [ 17 ].…”

Background Hospital waste management (HWM) practices are the core need to run a proper health care facility. This study encompasses the HWM practices in teaching hospitals of Peshawar, Pakistan and examine the enforcement of Pak HWM (2005) rules and risks through transmission of pathogens via blood fluids, air pollution during waste incineration and injuries occurring in conjunction with open burning and dumping. Methods A questionnaire based on World Health Organization (WHO) recommendations was used to survey the selected private and public teaching hospital (n = 16). Site visits and personnel observations were also included in the data. It was spatio-statistically analyzed using descriptive statistics, Krushkal-wallis and Fisher’s exact tests. Results The findings revealed that the lack of HWM practices in all surveyed hospitals (p > 0.05), besides statistical difference (p < 0.017) in waste generation/day. No proper segregation of waste from generation point to final disposal was practiced. However, the performance of private teaching hospitals (50%) was found better in terms of HWM personnel and practices. In surveyed hospitals, only nine hospitals (56.3%) were found with the incinerator facility while rest of the hospitals (43.7%) practiced open dumping. Moreover, operational parameters of the incinerators were not found satisfactory and located in densely populated areas and emitting hazardous gases. Conclusion Proper HWM practices are not being followed in the light of WHO guidelines. Hospital waste impose serious menace to healthcare workers and to nearby population. WHO issued documents for improving HWM practices but triggered no change in Pakistan. To improve the situation, insights in this context is need for enforcement of rules.
