Abstract Swiss waste‐to‐energy (WtE) plants are required to capture their CO 2 emissions by 2050 meet the net‐zero climate target, with options for underground storage (carbon and [CCS]) or utilization [CCU]). This opens up a synergistic opportunity petrochemical industry utilize captured as feedstock, potentially helping both sectors reduce carbon footprints. We conducted prospective footprint analysis on various strategies within WtE (CCU CCS) German ethylene production (CO ‐based ethylene, bio‐ethylene, fossil CCS), including scenarios of industrial symbiosis. While focusing these two countries, findings offer valuable insights applicable similar in other regions. All assessed pathways at least 60% relative reference scenario (no production). Bio‐ethylene direct air capture–based combined CCS exhibit lowest change impacts, achieving net negative when powered renewable electricity. However, all come trade‐offs: The availability sustainable biomass low‐carbon electricity is limited, future resource competition may delimit penetration technology combinations. could while utilizing existing infrastructure but does not eliminate from fuel extraction. Ethylene produced be viable interim solution until barriers overcome.
