Wool grease, from 18µm wool {AU}| wool scouring | AusLCI, U
Unit process Australia v00.00.001
This dataset represents the production of 1kg scoured wool. Australian wool is typically scoured in China, so this dataset starts with the transport of greasy wool from Australian port to China, and ends at the wool scourer gate. The included activities are: transport of Australian greasy wool to Chinese wool scourer (shipping and road transport), scouring, combing and baling. Documentation for this dataset can be found in the 'LCAgMetrics Methodology for developing Life Cycle Inventory' report, available at https://agrifutures.com.au/ It was developed as part of the LCAgMetrics project, a partnership between Agrifutures Australia and Lifecycles, funded by the Australian Government's Sustainability Reporting Uplift Grant as part of the National Agriculture Traceability Grants Program. Production volume: 23827292 kg/yr Energy value wool: 23.47 MJ/kg HHV Energy value grease: 40.75 MJ/kg HHV LHV energy contents used for energy allocation Geography: Australia Technology level: Represents current practices Time period: 2016-2017 Record: Anna Boyden; Tel +61(0)394171190; email: office@lifecycles.com.au; company: Life Cycle Strategies; Country: AU Generator: Anna Boyden; Tel +61(0)394171190; email: office@lifecycles.com.au; company: Life Cycle Strategies; Country: AU
