Abstract

Cilj ovog rada bio je izraditi analizu životnog ciklusa (LCA) procesa proizvodnje etanola kao biogoriva iz obnovljivih izvora. Analiza se temeljila na rezultatima dobivenim tijekom istraživanja na projektu „Održiva proizvodnja bioetanola i biokemikalija iz otpadnih poljoprivrednih lignoceluloznih sirovina“ (HRZZ-9158). Za izračun je korišten program SPIonExcel, a za kvanititativni prikaz održivosti procesa izračunata je specifična parcijalna površina atot čija vrijednost predstavlja utjecaj na okoliš te ekonomsku i ekološku održivost. Dobiveni rezultati su uspoređeni sa sličnim procesima opisanim u literaturi. Vrijednosti specifične parcijalne površine atot izračunate za proces predobrade pšenične slame su za Grubišić (2016) atot=3307.4 m2; Galić (2016) atot=4701.6 m2; Morikawa (2014) atot=16960.2 m2; Saha (2013) atot=14044.5 m2 za 1 kg proizvede glukoze iz slame. Niža vrijednost predstavlja veću održivost procesa s ekonomske i ekološke perspektive. Parcijalna specifična površina za proces proizvodnje etanola za Grubišić (2016) je atot=6541.877 m2, a za Galić (2016) atot=7782.06 m2 za 1 kg proizvedenog etanola. Kod Morikawa (2014) izračunato je atot=21401.5 m2/1kg, a za Saha (2013) atot=16701.9 m2/1 kg proizvedenog etanola. Razlika u rezultatima može se objasniti velikim utjecajem samog predtretmana sirovine na održivost ukupnog procesa.

Abstract (english)

The aim of this paper was a life cycle analysis (LCA) of the bioethanol production process from renewable resources. The analysis was based on the results obtained during the research on project "Sustainable production of bioethanol and bio-chemicals from waste agricultural lignocellulosic raw materials" (HRZZ-9158). The SPIonExcel program was used for the calculation, and for the quantification of process sustainability, specific partial area atot was calculated. Value of atot presents an environmental impact, and economic and ecological sustainability. The results obtained were compared with similar processes described in the literature. The values of the calculated specific partial area atot were calculated for the pre-treatment of wheat straw and are for Grubišić (2016) atot = 3307.4 m2; Galić (2016) atot = 4701.6 m2; Morikawa (2014) atot = 16960.2 m2; Saha (2013) atot = 14044.5 m2 for 1 kg of glucose produced from straw. Lower value represents greater sustainability of the process from an economic and ecological point of view. The partial specific area for the ethanol production process for Grubišić (2016) is atot = 6541.877 m2 and for Galić (2016) atot = 7782.06 m2 for 1 kg of ethanol produced. Calculation for Morikawa (2014) is atot = 21401.5 m2 and for Saha (2013) atot = 16701.9 m2 for 1 kg of ethanol produced. The difference in the results can be explained by the greater impact of the pre-treatment process of raw material on the sustainability of the overall process.
