Ethanol, from wheat and starch waste {AU}| | AusLCI, U
Unit process Australia v00.00.001
Included processes:Process The process begins with the supply of fermentation in distillation process and ends with the production of ethanol. Remark: This is the allocated process for ethanol from the coproducing process which produces both ethanol and dried distillers grains and solubles (DDGS). The input process is scaled to the production of 1 L of ethanol. Geography: Refers to an average production in the Australia. Technology: Average Time period: Data collected for 2012 Version: 1.0 Record: ata entry by: Tim Grant Telephone: 0061 408104977; E-mail: tim@lifecycles.com.au; Company: LCS; Country: AU Generator: Generator/publicator: Tim Grant Telephone: 0061 408104977; E-mail: tim@lifecycles.com.au; Company: LCS; Country: AU
