Optimising integrated water reuse and waste heat recovery in rendering plants and abattoirs

The increasing pressure nationally on water supply resources and the environmental impact of discharging wastewaters has placed a high priority on the need to use non-conventional water sources. Non-potable water streams have been effectively converted to potable supplies using a range of technologies outside the meat industry. Midfield Meat International’s rendering subsidiary, Midfield Co-Products, had specific issues with the disposal of wastewater that was threatening its future viability. This plant was seen as an ideal model for investigating the reuse of wastewater to alleviate hydraulic load on the existing pond system.
