List of processes that are major contributors for the identified impact categories for both petro-FA and PKO-FA

	Petro-FA	PKO-FA
Climate change	N-Olefin  Ethylene  Fuel combustion (process)  Aluminum powder  Chemical plant (<5 %)	Land use change for palm plantation  Palm plantation operation  Fuel combustion emissions (transportation)
Fossil fuel depletion	N-Olefin  Ethylene  Fatty alcohol production (<5 %)  Fuel combustion (process)  Aluminum powder (<5 %)	Fuel combustion (process, transportation)  Electricity production
Natural land transformation	Oil extraction for n-olefins, ethylene and fuel for transportation  NG extraction for fuel for process  Chemical plants  Aluminum powder	Land use change for palm plantation  Land use change for oil extraction (<0.3 %)
Eutrophication	Sulfidic tailings for production of Copper used in chemical plants  Spoil from mining of coal used for electricity production  Production of Gold used in electronics for chemical plants  Treatment of dross from electrolysis for Copper and Aluminum production  Incineration of solid waste	Fertilizer use for palm plantations  Irrigation for palm plantations Sulfidic tailings for production of Copper used in chemical plants  Spoil from mining of coal used for electricity production
Agricultural land occupation	Wood used for building material in chemical plants (<0.1 % of impacts for PKO-FA)	99+% from palm plantations
Water depletion	Aluminum powder (~50 %)  N-olefin  Chemical plant  Electricity used during FA production	Palm FFB growth  Fuel combustion (process, transportation)  Chemical plant  Electricity used during FA production
Particulate matter formation	N-Olefin  Ethylene  Fuel combustion (process)  Aluminum powder  Electricity used during FA production	Palm FFB growth  Fuel combustion (process, transportation)
