South Pacific Laundry commenced operations in 1990 and is an industrial laundry servicing the hotel and restaurant sectors. The laundry has the capacity to process 1000 tonnes of linen per week and operates every day of the year. The business operates in three locations – Brunswick East, Epping and Broadmeadows – but is in the process of consolidating all its operations to the Broadmeadows site.
The laundry has a stated commitment to reducing its impact on the environment. It has drastically reduced water usage by installing a water recycling plant utilising ceramic filtration and reverse osmosis technology, allowing the laundry to recycle up to 65% of its used water.
In 2014 South Pacific Laundry successfully applied for a $5,000 grant from Sustainability Victoria toward the cost of an energy assessment of its operations at the Brunswick East site. The laundry's energy consumption comes from the operation of 2 boilers, 5 batch washers, 14 dryers, 6 ironers, a water recycling plant, a dry cleaner and the office area.
'We have invested heavily in cutting edge technology to increase productivity. Keeping our machines working efficiently to their full capacity is a top priority to us,' said Ray Hayes, General Manager.
The energy assessment identified opportunities to save more than $300,000 per year and reduce greenhouse gas emissions by the equivalent of more than 2000 tCO2.
The assessment found that the boiler steam traps were not operating effectively resulting in steam loss in some and condensate build up in others, both reducing the efficiency of the boiler. The assessment report identified the replacement of these steam traps as the top opportunity for the business. Three steam traps were replaced for a total investment of $5,000 with $3,000 of that cost covered by a bonus payment from Sustainability Victoria.
In 2015 the Laundry successfully applied for a further $35,000 from Sustainability Victoria toward the $116,000 the cost of overhauling its two boilers including the installation of variable speed drives and economisers.
Having an efficient plant reduces our overall environmental footprint, saves tens of thousands of dollars per year and helps to keep us competitive in a very tough market.

The new steam traps are expected to save South Pacific Laundry an estimated $28,000 per year, equivalent to 232 tCO2. 'The new steam traps have improved the consistency of the steam throughput to the ironer bed, and as such improved its efficiency and the end product of our linen. It has also helped us boost our preventative maintenance scheme,' said Mr Hayes.
The overhaul of both boilers including installation of variable speed drives and economisers will reduce electricity use by an estimated 32,412kWh or 20%, and gas by 543Gj or 14%, saving $37,700 and the equivalent of 316 tCO2 per year.
Overall estimated energy efficiency improvement from all the implemented actions is 4 to 6% representing total annual savings of more than $65,000.
'The funded projects have also helped boost our preventative maintenance scheme ensuring maximised productivity, as well as improving occupational health and safety,' said Mr Hayes.
