| Abstract |
Circular economy and bioeconomy factors has driven the economy sectors towards sustainable choices. Chemical industry, as stated by the Joint Research Centre of the European Commission, has a potential to reduce 36 % of the greenhouse gas (GHG) emissions by 2050 [1] mainly linked with introduction of emerging energy technologies. Ethylene, chlorine, ammonia and hydrogen are important chemicals for such reduction as they are the most worldwide produced chemicals (16 % of the total production in 2050 for ethylene, 11 % for chlorine and 6 % for ammonia). Meanwhile planned GHG reduction potential for these chemicals, through introduction of compression and separation technologies, is estimated as 75 % for hydrogen, 54 % for ammonia, 31 % for chlorine and 27 % for ethylene. The aim of the study is to perform an indicator analysis (raw material consumption, emissions produced and associated costs per one tonne of bioethylene) of bioethylene production pathways focusing on the following raw materials - corn, manioc, sugar cane, sugar beet, wheat and conifer.
