Table 3.
Compilation of climate change (CC) impact and waste generated (W1) values of the base case and described scenarios. ΔD% describe difference in the value of the scenario examined with respect to the single-use surgical face mask base case scenario. ΔR% describe difference in the value of the scenario examined with respect to the EFL reusable face mask base case scenario.
