Wheat and starch waste to ethanol distillery operation {AU}| | AusLCI, U
Unit process Australia v00.00.001
Included processes:Processes include the supply of agricultural inputs fermentation of wheat and wheat starch waste distillation and dehydration of ethanol. Remark: This is an un-allocated coproducing process which produces both ethanol and dried distillers grains and solubles (DDGS). The process is scaled to the production of 1 L of ethanol. Inputs to the process include both wheat and waste from wheat starch processing. Geography: Refers to an average production in the Australia. Technology: Average Time period: Data collected for 2012 Version: 1.0 Record: Data 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
