12.0pt;margin-left:0in;text-align:justify">It is a known fact
that the demand for polymers and chemicals is increasing at a high pace, with
studies predicting that demand for polymers will roughly double within the
coming 15 years. In order to meet this demand, several investments in new
capacity for the production of olefins and subsequent products are being made
at a global scale. Consequently, ever-increasing amounts of fossil resources
are being utilized, which puts additional strain on the environment.

12.0pt;margin-left:0in;text-align:justify">Steam cracking is
already a mature process, and revolutionary technologies are rather scarce in
the field. In this context, with the aim of improving the environmental
footprint of the process and its products, sustainable feedstock usage is one
of the most straightforward, beneficial and scalable solutions readily
available for cracker operators.

12.0pt;margin-left:0in;text-align:justify">In this paper,
technical aspects of Neste’s renewable hydrocarbons
are discussed, focused on their suitability as a drop-in steam cracker
feedstock, as well as their sustainability record and environmental impact,
which is typically evaluated by means of a life-cycle assessment (LCA). It has
been determined that the environmental benefit offered by bio-based
Polypropylene (PP), produced using steam-cracker-based propylene is substantial
[1]. Calculations indicate up to 80% lower CO2 eq. compared to
conventional fossil PP [2].
