Abstract

A carbon dioxide negative process, for the preparation of a polymeric product, comprising the steps of: a) Capturing carbon dioxide (1, 11.1, 11.2) from a gas comprising carbon dioxide, in particular from air or exhaust gas; b) Converting at least a part of the captured carbon dioxide (2, 12.1) to an intermediate product comprising an olefin; c) Optionally, subjecting the olefin of the intermediate product to a derivatization reaction (3, 13.1, 13.2) to obtain an olefin derivate; d) Further subjecting the olefin and/or olefin derivate, in particular with at least one further monomer, to a polymerisation reaction (4, 14.1, 14.2) to obtain a polymeric product; wherein at least for step a), in particular for at least steps a) and b), especially for all steps a) - d), energy required for performing the process step(s) is provided in the form of renewable energy.
