We have included these important steps in our life cycle assessments, however, our syntheses utilized the more readily accessible samples of superabsorbent polymer used to manufacture diapers at P&G. To obtain U.S. Patent Application 2021/0054248 A1 (Februrary 25, 2021). M.C.C., S.G.K. April 2021 was the deadliest month since the pandemic began: nine capital cities reported more deaths than births, and, by 25 April, the number of COVID-19 deaths in 2021 surpassed that reported in 2020. Over the last decades, the completeness of death registration has improved steadily in Brazil43, and data completeness is likely to be similar for 2019 and 2020. Wernet, G. et al.

Because this recycling method should be amenable to waste polymer as the feedstock, it offers a more sustainable alternative to diaper disposal in a landfill or incineration. From April to December 2020, an emergency basic income program mitigated the challenges imposed by the pandemic37 (for example, unemployment), but this benefit ended in December 2020. Huang, C. et al. The corresponding VW for each adhesive is the rectangular region bounded by these four moduli. e65 declined by a larger percentage for males than females in all states, reflecting mens higher risks of dying from COVID-19 (ref. Vital Strategies. From an energetic standpoint, the CED is reduced by 18.8% and 18.6% with the sonication scenarios, and further reduced (by 24.8%) in the scenario without sonication. Trans. Among the states, Amazonas, Rondnia, Roraima and Mato Grosso had the largest declines in e0 in both 2020 and 2021 (Fig. and M.T.R. Thank you for visiting nature.com. Soil Environ. 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.

States are colored according to major regions. The consequences of that death toll can be measured by e0, which indicates the average number of years a newborn would be expected to live if born in a specific year and subject to the prevailing mortality rates in that year throughout life. Offensive waste valorisation in the UK: assessment of the potentials for absorbent hygiene product (AHP) recycling. 3b). Here, we assumed that individuals who did not die of COVID-19 in the first 4 months of 2021 would be subject to the 2019 age group-specific and sex-specific mortality rates. We made the assumption of proportionality between forces of decrement from cause i (or all causes except i) and the force of decrement from all other causes combined8,45.

Metcalf, Stefano Amore, Emanuela Puppo, Giuseppe Liotta, Ariel Pablos-Mndez, Simone Villa, Richard Alan Cash, Megan ODriscoll, Gabriel Ribeiro Dos Santos, Henrik Salje, Nature Medicine Moreover, the life cycle assessments, which utilized soiled diapers as the starting point, demonstrated that these open-loop recycling methods outperform the conventional routes from petroleum-derived feedstocks on nearly every metric, including for the key LCA metrics of global warming potential and cumulative energy demand. Given a growing emphasis on sustainability within the polymer industry, including calls to increase the circularity of polymer production12, this LCA provides an important metric for evaluating approaches to polymer recycling.

While catalytic depolymerization methods20 can, in principle, proceed without side-chain degradation, they have not yet been demonstrated for commercial sources of polyacrylic acid. 5, 501516 (2020). However, this approach can lead to low yields due to competitive ester hydrolysis41,42 and catalyst deactivation by water43. Considering this factor, the optimized conditions involved sonicating a 2.5% w/v solution for 1min to give an Mw ~360kg/mol, and a 5.0% w/v solution for 2min to give a Mw of ~330kg/mol37. 10, 4153 (2021).

Across states, the largest declines were estimated for Amazonas (3.14 years), Amap (2.46 years) and Par (2.44 years). This result suggests that most crosslinks had been hydrolyzed within 15h (Supplementary Fig. Bjrn, A., Owsianiak, M., Molin, C. & Laurent, A. in Life Cycle Assessment: Theory and Practice; (eds) Hauschild, M.

In closed-loop chemical recycling, chemical transformations are used to cleave the polymer into its monomers (depolymerization), or to create a polymer with equivalent function12. https://www.ipea.gov.br/portal/index.php?option=com_content&view=article&id=37022&Itemid=448 (2020).

Because in-hospital COVID-19 deaths represent 89% of all COVID-19 deaths reported in 2021, we use them to proxy for the agesex distributions of all COVID-19 deaths. Previous studies used this approach to estimate life tables in the presence of COVID-19 (refs. We abstracted death data on 18 May 2021, for all states, as reported through 30 April 2021 (n=209,458 confirmed COVID-19 deaths). Article J. Phys. To date, most diaper recycling efforts14 have focused on the cellulosic components, which can be biodegraded, incinerated to generate steam, pyrolyzed, or fermented to generate bioethanol15. Slider with three articles shown per slide. We assumed that those dying in a given month from any cause contributed, on average, 0.5/12 person-years, whereas the contribution of survivors was 1/12 person-years. Collias, D. I. et al.
