Ethanol, from molasses, at plant {AU}| | AusLCI, U
Unit process Australia v00.00.001
Included processes: This inventory has been developed as part of the AusAgLCI initiative funded by a partnership of Australian Research and Development Corporations (RIRDC, CRDC, GRDC, SRDC, HAL, MLA, DA, FWPA) and Research Agencies (CSIRO, USQ and Q DAFF), with technical support from Life Cycle Strategies. More detail on inventory development can be found in the 'AusAgLCI Methodology for developing Life Cycle Inventory' documents located at www.auslci.alcas.asn.au.fermentation in distillation of ethanol from molasses supplyand the use of silage back on farms . Remark:.Silage is not treated as an economic byproduct has is used back on sugarcane farms. This is recognised as a simplification ; Geography: Refers to an average production in the Australia.
