Use of residual greenhouse gases, such as carbon dioxide, to prepare useful and valuable polymers has long been of interest to researchers. This is a rare example of a process that consumes carbon dioxide as a reagent. It allows 30 to 50% of the mass of a polymer to come from carbon dioxide.
In this respect, it is important to analyse the environmental impacts of the promising process, focusing on:

  • Carbon dioxide greenhouse gas cycle.
  • Benefits of using an alternative to petrochemicals.

Environmental impacts will be assessed on the basis of the LCA, life cycle assessment. Life cycle analysis will provide environmental impacts, which will be calculated using actual data, Ecoinvent databases and openLCA software.
