SHARC sighting in Melbourne!!

42% energy savings to be exact. But let’s go backwards a little. How are we off-setting this client’s GAS bill? Quite simple really. Like many manufacturing/industrial businesses, trade waste is an inevitable part of their daily processes – some creating by-products as an additional revenue stream.

But what about the main carrier for these ingredients? In this case….HOT water. The Australian Wool Testing Authority in Kensington, nr Melbourne produces 98,000lts of 65°c waste water, 5 days per week. Boilers then heat 13°c town water to 85°c to facilitate the wool testing procedure and the waste cycle begins again.

As part of a suite of environmental and energy efficiency upgrades, ETS provided the patented SHARC heat recovery system to capture this heat lost to sewer every day. Waste water is cleaned up to remove oils and waxes from the wool and sent to the SHARC system where heat is exchanged to the incoming supply. Town water is now increased to 62°c – purely from the waste heat. The difference is made up by gas boilers, or in other case studies, super-efficient heat pumps with a COP of 5.

  • 42% reduction in gas consumption
  • Payback of less than 3yrs
  • CO2 off-setting
  • Cooler waste water temps.
  • Secondary business savings

These figures are based only on gas savings and do not take into account further reductions in utility charges for sewer water treatment – waste water temperature has now been lowered by 15°c as a result of the SHARC.  Factor in the future potential for water recycling and things start to get even more attractive.

In an age where manufacturing costs are threatening the very existence of these businesses and local jobs, implementing ways to lower operational costs has to be high on the agenda. With various funding and grant models available, ETS can assist your business or new construction project with a turnkey service to find sustainable ways of both producing and using energy.
