Meredith Dairy heats up with Wood Waste

Meredith Dairy heats up with Wood Waste

In March 2016 Dragon NRG Pty Ltd installed a 240 kW biomass boiler for Meredith Dairy to reduce their reliance on LPG for water heating. The boiler was originally fuelled by woodchips sourced from Pyrenees Sawmill near Beaufort, but the dairy now produces its own wood chips on-site. The Camerons expect to be able to sustainably harvest timber from their property by maintaining a cycle of planting, growth and harvesting of trees as an integrated and holistic component of their farm’s operation.

Key points

  • The total cost of the upgrade was $310,000, including the purchase and installation of the wood-fired boiler ($120,000).
  • The biomass boiler has reduced Meredith Dairy’s LPG consumption by an estimated 1,600 litres per week ($76,500/year).
  • The cost of producing their own woodchips is estimated to be around $31,200 annually giving an overall cost saving of $45,300/year. This equates to a simple payback period of 2 years, 8 months.
  • The new system has reduced the dairy’s emissions of greenhouse gases by approximately 230 tonnes per year.
