When closed-loop processes are unavailable, an alternative, known as open-loop chemical recycling can be utilized. Several provisional patent and patent applications have been filed based on this work. Moreover, the route involving just decrosslinking and esterification (i.e., no sonication) has the potential to be industrially scalable, providing a sustainable solution to a longstanding waste problem.

Assuming that death rates would have been equal to 2019 all-cause rates in the absence of COVID-19, COVID-19 deaths in 2021 have already reduced e0 in 2021 by 1.8 years, which is slightly larger than the reduction estimated for 2020 under similar assumptions.

A large study showed a higher risk of death 6 months after COVID-19 diagnosis, even among those who did not require hospitalization34. Therefore, we estimated the provisional decline in life expectancy in 2021 thus far; this estimate is based on the DT19 method noted earlier but, in this case, adding confirmed 2021 COVID-19 deaths to the deaths expected among those who did not die of COVID-19, who are assumed to be subject to 2019 mortality rates for the remainder of 2021 (Supplementary Table 11).
