R. 63, nr 3

The article presents the definition of bioindustry, in particular biorefinery. The technology for obtaining synthetic fuel EtG (Ethanol to Gasoline) in a plant using bioethanol from food waste was presented. The physicochemical properties of EtG fuel were presented. EtG fuel stands out due to its limited content of benzene and sulfur and a low content of mechanical impurities and heavy metals. EtG fuel can be considered a replacement fuel for motor gasoline. The results of exhaust emissions tests from vehicles with spark-ignition engines in the WLTC test on a hot and cold engine were presented. It was found that EtG fuel is characterized by lower specific distance emissions of CO, NOx, and CH4 and slightly higher specific distance emissions of NMHC when starting a cold engine compared to gasoline, while the specific distance emission of CO2 for both fuels were very similar.
