  • $775 savings over 20 years
  • 37% reduction in gas consumption
  • 4.5 year 'simple' payback

The Australian Wool Testing Authority (AWTA) is the largest wool testing organisation in the world, providing testing and certification of wool yields, fibre diameter, vegetable matter content, sample length, sample strength and more. In testing and providing independent certification for wool products, AWTA’s Melbourne plant produces over 98,000Ls of 65°c waste water each weekday.
In today’s manufacturing industry, energy costs are steadily rising while margins fluctuate somewhat unpredictably. Managing waste and recouping costs is integral to the survival of many small and large businesses across Australia. Environment Technology Solutions (ETS), a leader in energy efficiency and sustainability solutions, works together with clients to achieve energy savings which not only help to lower costs, but decrease emissions such as CO2. 

ETS Solution

AWTA’s Melbourne plant requires the heating of town water from 13°c to 85°c by gas-powered boilers, in order to facilitate the wool testing procedure. ETS deduced that the resultant waste water, at a temperature of 65°c, could be harnessed during the waste cycle in order to lessen AWTA’s reliance on gas power.
ETS provided AWTA with the patented SHARC heat recovery system, which captures waste heat that would otherwise be lost to sewerage each day. This recovered water is filtered to remove oils and waxes, before being processed by the SHARC system. The incoming heat is captured by the system and used to heat the incoming town water supply. Where previously the water had to be heated from 13°c by the plant’s boilers, it is now heated to 62°c by the SHARC heat recovery system. This heat recovery has resulted in a 37% saving in gas heating costs for AWTA, which will equate to an enormous $775k over 20 years.
The ‘simple’ payback of the installation is expected to take just 4.5 years, and further savings are being made by the business in reduced waste water treatment. The implementation of heat recovery systems like the SHARC system lower operating costs for businesses, while also offsetting emissions. These kinds of sustainable solutions are helping businesses all over Australia to manage their energy expenditure and insure their operations well into the future.
