  1. Biopolymers are preferable to synthetic polymers in terms of their safety, but they also possess health issues, such as bioaccumulation, carcinogenetic properties, air pollution, and respiratory illness. Technologies have to be developed further to remove the health impacts of biopolymers .

  2. 11 Οκτ 2021 · This Review argues that polymer selection and product design must incorporate strategies for end-of-life management and strive to eliminate, or at least minimize, environmental persistence of ...

  3. 16 Φεβ 2021 · Future evaluations of the environmental risks of polymers would greatly benefit from improved public availability of data, and further investigations of the behaviour and effects of polymers under environmentally relevant conditions.

  4. 13 Απρ 2023 · However, the environmental exposures and risks of WSPs with different functions remain poorly understood. This paper provides a critical review of the usage, environmental fate, environmental persistence, and biological consequences of multiple types of WSPs in commercial and industrial production.

  5. Whilst knowledge gaps concerning PBT characteristics of synthetic polymers still exist, we argue that the precautionary principle should apply. Water-soluble, liquid and semi-solid polymers

  6. 7 Οκτ 2022 · Introduction. Plastic pollution in the environment is one of the most critical environmental challenges today, affecting ecosystems as well as humans (Liwarska-Bizukojc 2021). In 2018, about 250 million tons of plastic garbage were produced globally.

  7. 20 Σεπ 2022 · As an example, some researchers are focused on shifting from fossil-fuel-derived chemical feedstocks to biomass-derived monomers and carbon dioxide. A related approach involves functionalizing natural polymers through synthetic processes.
