Obviously with the significant increase in people on site, the amount of waste generated during the shutdown had the potential to exceed our internal target for waste to landfill for 2009 in just one month! Not only is this a poor environmental outcome, it comes at a significant cost to the business. This reduction can be attributed to the concerted efforts by our employees and contractors and the 81 waste audits that were conducted over the duration of the shutdown. Seven Environmental Near Misses relating to incorrect waste segregation were raised as a result of these audits. This allowed small issues to be corrected immediately before they became a greater issue. The volumes of recyclable waste produced during the shutdown include: > 9.5 tonnes of scrap steel > 10 m3 of timber scrap > 540 kg of food scraps The 2009 target for non-recyclable materials sent to offsite landfill is 8 tonne. Currently, YTD we have generated a total of 7.2 tonne. Although we are still underneath our target, we need to maintain our concerted waste management effort for the remainder of 2009. This will be a tough challenge for a shutdown year! In comparison to the previous 2005 shutdown we have made a huge improvement. The shutdown tally for non-recyclables in 2005 was 8.9 tonnes. However, this figure was 3.7 tonnes in 2009 - over 200% improvement! This great result was attributable to everyone “doing their bit” and taking the time to segregate their waste correctly. Lets keep it up for the remainder of the year in order to meet our 2009 target!

Apart from wearing the Community Relations Officer’s hat for the duration of the shutdown, my role was to conduct waste audits around the station, to promote good waste management practices as well as the usual environmental and occupational hygiene support to the station. How did you find your first shutdown? The lead up and first week was particularly frantic, but it did settle down. Thanks must go to the Civil Maintenance guys who prepared well for the waste management side of the shutdown, making my job much easier. The had arranged ample bins, appropriate signage and did a great job of the actual waste collection. Any learnings for the next shutdown? I think there may be some more opportunities to further develop the systems that we put in place, but ultimately it was a great outcome. Thanks Nicci ...NICCI MARRIS
