REPORT
shutdown waste management gets 10/10
Alcoa Anglesea’s 2009 maintenance shutdown
successfully ended on Saturday May 23 with focus
on the area of waste management at an all time
high. 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!

OUR ENVIRONMENT AND OUR EMPLOYEE
Hi Nicci, what was your role during the 2009
Shutdown?
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
