Industrial Symbiosis in Australia could be driven by one or more of the following factors: [2 marks] Select one: O A. Reduction of inventory for waste storage OB. A, C and D as above OC. A and B as above O D. Availability of practical technology to convert renewable materials into useful product OE. Low cost for waste disposal OF. Improved air and water quality requirements Identify the goal (or goals) of a Eco-Industrial park: [2 marks] Select one: O A. To improve the natural resource utilization efficiencies of the participating industries OB. A and C as above OC. To improve the environmental performances of the participating industries OD. A, B and C as above O E. To improve the economic benefits of the participating industries An alumina refinery is using process carbon dioxide (CO) from a nearby fertilizer plant to reduce the alkalinity of its bauxite residue, thus reducing environmental risks and significant ongoing management related to bauxite residue storage areas while also leaving options open for additional processing of the residue into other useful products at a future stage. The alumina refinery uses 12 kg CO for reducing alkalinity of 1 tonne bauxite residue, while the refinery produces 70,000 tonnes of alumina per year. The bauxite which is refined to alumina is low grade bauxite (40%). The refinery is expected to reduce carbon taxes for sequestering CO2 from the neighbouring plant. The Government has just implemented Carbon tax of $20/tonne of CO2 emitted. Calculate the economic and environmental benefits from this industrial symbiosis. [4 marks] Select one: O A. Greenhouse gas emission reduction by 840 tonnes and carbon tax avoidance of $10,080 OB. Greenhouse gas emission by 2,100 tonnes and carbon tax avoidance of $42,000 O C. Greenhouse gas emission by 1,260 tonnes and carbon tax avoidance of $25,200 O D. Greenhouse gas emission reduction by 504 tonnes and carbon tax avoidance of $6,048
