RFI - Attachment 3 - Operational Waste Management Plan · MCU22/0094

TTM have audited a number of operational childcare sites to ensure accurate advice on waste management
requirements is conveyed to clients. TTM conducts audits based on the maximum waste capacity of the centre
– quantity of bins multiplied by the service frequency – rather than by the actual volume collected to account
for variances in disposal volumes that may occur for various reasons. Furthermore, in view of different
operational hours and days between centres, TTM averages audit data based on a weekly cycle of total volume
generated per week and applies to centre GFA (if known) and per placement to provide either a L / 100m2 /
Week or L / Placement / Week volume.

TTM’s audit results find that most childcare centres fall within the refuse generation rates prescribed by City
of Melbourne Council (350L / 100m2 / Week) or City of Sydney Council (325L / 100m2 / Week – 5 day operation,
general waste) with maximum outlier results at 420L / 100m2 / Week which equates to a maximum
31L / Placement / Week. It is important to note that the overwhelming majority of waste generated within
childcare centres occurs as a result of kitchen activities (if included) and from consumables, predominantly
nappies. Given the putrescible and highly odorous nature of the waste TTM consider a minimum twice-weekly
collection frequency to be mandatory in preventing detrimental effects to the amenity of the development
and neighbouring properties.

In detailing the waste management strategy, the OWMP will consider and reference the preceding information
with specific regards to anticipated refuse generation calculations, refuse storage location, service frequency
and refuse collection.
