DDGS, from wheat and starch waste, at plant {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 ofdried distillers grains and solubles (DDGS) Remark: This is the allocated process for DDGSfrom the coproducing process which produces both ethanol and 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
