Waste treatment, sludge, at landfill {AU}| | AusLCI, U
Unit process Australia v00.00.000
Included processes:The process begins with the input of sludge to landfill and includes processing of the landfill and emissions over the landfill life. Remark: Process is for the disposal f sludge in landfill using the assumptions outlined in the National Inventory Report Geography: Refers to an average production in the Australia. Technology: Average Time period:2012 Version: 1.0 Record: Data entry by: Tim Grant Telephone: 0061 408104977; E-mail: tim@lifecycles.com.au; Company: LCS; Country: AU Generator: Data entry by: Tim Grant Telephone: 0061 408104977; E-mail: tim@lifecycles.com.au; Company: LCS; Country: AU
