QUESTION:
Thesis on the Material flux analysis of Lead in Sydney, 28 Sep 2005, New South Wales Australia Hi, I am a student from UNSW Civil and Environmental Engineering. I am currently doing a thesis on the material flux analysis of Lead in Sydney. Am trying to develop a model which would present the quantities of lead emitted into the environment. I am also trying to develop a feedback loop on the lead acid batteries generation and its recycling rates. Was wondering if You would happen to have an estimates of Greenhouse gas and CO2 emissions for both lead mining of raw materials and also emissions from recycling Lead acid batteries. Appreciate the help Regards Darryl EMAIL TWO ----- Original Message ----- From: "Darryl Chew" To: The LEAD Group Sent: Wednesday, September 28, 2005 5:32 PM Subject: Re: Thesis on the Material flux analysis of Lead in Sydney Hi Elizabeth, Thanks a lot for the links, I have actually found some info on the various energy requirements and emissions from Pasminco environmental report 2000. It would seem that recycling processes requires more energy and releases much more emissions then it would require to mine raw lead. Does that sound about right with ?? I also believe that the cost of raw lead is still cheaper than recycled lead at present. Is that true?? If so what would be the benefits of improving recycling rates of lead acid batteries?? What i am trying to show in my thesis is that improvements in increasing recycling rates would be helpful to the environment. I am also trying to play around with various variables to see if there is ways to reduce the amount of raw lead required. Any suggestions?? Appreciate you help. regards Darryl |

ANSWER: 28 Sep 2005 Dear Darryl, I guess I don't understand what you mean by asking for information on lead mining for a Thesis on the Material flux analysis of Lead in Sydney (as no lead mining occurs in Sydney), unless you actually mean you are "doing a thesis in Sydney on the Material flux analysis of Lead in Mining and Battery Recycling." Is that what you mean? Theoretically, you should be able to obtain all the estimates you need by searching the National Pollutant Inventory at www.npi.gov.au for all the Australian lead mining companies: 1. BHP Billiton www.bhpbilliton.com 2. Perilya www.perilya.com.au 3. Xstrata www.xstrata.com 4. Zinifex www.zinifex.com 5. Consolidated Broken Hill (CBH) www.cbhresources.com.au 6. Magellan Metals - owned by Ivernia West Inc www.ivernia.com 7. Kagara Zinc Ltd www.kagara.com.au/default.asp as well as for the two operating lead acid battery recycling plants (50% owned by Zinifex) in Australia: 8. Australian Refined Alloys (ARA) Sydney www.zinifex.com 9. Australian Refined Alloys (ARA) Melbourne www.zinifex.com The reason I say "theoretically" is because personally, I would not trust the data on NPI - it is mostly estimated by the operator - but it's probably your only source of info (unless the environmental reports of the companies have this data) so there's the dilemma. Good luck. Keep in touch and let me know what you find out. Yours Sincerely Elizabeth O'Brien, Manager, Global Lead Advice & Support Service (GLASS) - incorporating the (GLASS) - run by The LEAD Group Inc. PS there would be two other sources of estimates for two proposed lead acid battery recycling facilities in NSW which are not yet operational. Is this of any use? |
