Bold means statistically significant.
kgCO2e, carbon dioxide equivalents— equivalence of 1 kg of landfill waste to 1kgCO2e and 1 kg of RMW to 3kgCO2e was applied.11–16
*P value for preintervention versus 1 month after intervention based on paired-samples t-test.
†P value for 1 month after intervention versus 4 months after intervention based on paired-samples t-test.
RMW, regulated medical waste.
