Study to highlight water recycling in food production

0

New research being undertaken by the Australian Water Recycling Centre of Excellence is examining the increasing use of water recycling in food production and manufacturing.

Led by CSIRO Animal, Food and Health Sciences and the Water for a Healthy Country Flagship, the project will collaborate with industry to demonstrate higher-value water recycling opportunities that deliver economic, environmental and social benefits to the agri-food industry and community.

The research will examine opportunities for water recycling across the agri-food chain, with particular focus on food manufacturing, dairy and meat industries.

Project director Jay Sellahewa says the project will focus on current industry challenges, including regulatory and policy pressures, and the value proposition (an analysis of all factors to determine if water recycling stacks up as the best option). It will also develop strategies to increase acceptance by consumers and enhance the sustainability positioning with customers.

“The ultimate goal is to reduce the reliance of fresh water throughout the agri-food supply chain,” Mr Sellahewa says.

“This could be achieved by increasing the amount of water used for irrigation of crops by treating effluents from food processing plants and by increasing the amount of water recycled within food manufacturing plants.

“Outcomes of this work will include informing industry practices on strategies to increase water recycling, a tool to enable industry to make decisions on recycling water based on the value proposition and available technologies, and communicating positive messages in consuming foods associated with recycled water to help increase consumer confidence.”

Centre chief executive officer Dr Mark O’Donohue says the project was a good example of the multi-disciplinary work being done by the Centre.

“This project is using rigorous science-based research in partnership with some of the biggest and most credible industry organisations in Australia such as Meat and Livestock Australia, Dairy Australia and the Australian Food and Grocery Council,” Dr O’Donohue says.

“As a centre focused on water security the applications of this research for food security are very exciting.”

More than $2.3 million has been committed to this project, which has linkages with the Centre’s other work in examining public attitudes to and perceptions of water recycling.

The linkages between projects were examined at a recent workshop where project leaders had the opportunity to engage and discuss common themes of their individual projects.

The workshop’s focus was to ensure the Centre’s research outcomes have the greatest impact on a national scale – enhancing efficiency, expansion and adoption of water recycling in Australia.

The Australian government has committed $20 million in funding over five years to the Australian Water Recycling Centre of Excellence, through the Water for the Future initiative.
