Heinz Watties


Reducing Solid Wastes from Waste Water


Girgarre


Background

Heinz Wattie's Australasia is a fully owned subsidiary of HJ Heinz International, a worldwide manufacturer of processed food products, with three plants in Australia. The Girgarre site, located in central Victoria, processes fresh tomatoes into manufacturing paste. Recently, three new processing lines have provided capacity to produce a range of tomato-based retail products such as sauces and ketchup. The site processes 85,000 tonnes of fresh tomatoes and 15,000 tonnes of finished goods annually.

The Heinz company is committed to continually improving its environmental performance. Heinz requires all its southern hemisphere plants to be ISO14001 compliant by March 2002.

Waste management focus

Analysis of the results of the benchmarking program under-taken by the company identified reducing solid wastes from waste water as one of the best initial opportunities to improve its environmental performance and its economic efficiency.

Waste management program

All the waste water generated from the site is treated in waste-water dams and then reused to irrigate dairy pasture. This waste-water treatment facility would directly benefit from reduction of solid wastes entering our waste water.

The first project in this regard was to reduce the volume of cleaning chemicals used on site.

The next project is to reduce the volume of tomato fruit entering waste streams. We expect the project to generate significant savings. Some preliminary machinery modifications have already been carried out.

Results

The project to reduce the volume of cleaning chemicals used on site was most successful. Cleaning chemical use was reduced by 70 per cent, a substantial saving.

Next stage

Heinz Wattie's plan to integrate the efforts of environmental bench-marking with ISO14001 requirements so that significant areas of waste creation on this site are monitored as a standard procedure. In this way they will be able to track the performance efficiency of this plant and factors that influence its performance.

Reducing gas and power consumption

Gas and power consumption has already been measured against daily throughput. This season they will install steam meters and hour meters on major equipment so as to obtain regular and reliable data.
