Teys Australia, the second largest beef processing and cattle feeding company in Australia, has invested in upgrading its wastewater treatment plants, including the plant at Wagga Wagga, NSW, to reduce its greenhouse gas emissions and to minimise the beef processor’s reliance on fossil fuels.
Planning for the upgrades to the Tamworth plant began in 2010 with an ambitious agenda to drive environmental efficiencies through reducing nutrient levels in the wastewater, enhance water treatment processes, improve energy efficiency and increase renewable energy use. Construction finished in 2012. Teys replicated the technology at the Wagga Wagga plant in 2013.
The systems include both a Covered Anaerobic Lagoon (CAL) designed to capture methane rich biogas to generate renewable energy for each site and replace natural gas and coal in site boilers and a Biological Nutrient Removal (BNR) system designed to treat each plant’s processed waste water to a higher quality, opening up the potential for a greater number of reuse and discharge opportunities.
