How we reduce water use in our avocado packing processes by 30 percent

At an avocado packing site, water does more than rinse fruit. It supports line sanitation, equipment washing, cooling and floor cleaning, and consumption can rise with fruit size, throughput and weather. Treating every stage as part of one water system makes hidden losses visible and gives teams a clear basis for reducing demand.

Our program to reduce water use in avocado packing by 30 percent combines measurement, process redesign, controlled water recovery and operator training. It is a practical response to a resource that communities and growers depend on, and it is designed to maintain food-safety controls rather than trade hygiene for a lower utility bill.

Why water efficiency matters beyond the packhouse

Australia makes this work especially relevant. Sydney and Melbourne are major grocery markets for fresh produce, while prolonged dry periods can trigger metropolitan watering restrictions and put pressure on growers across the Murray–Darling Basin. A packhouse can operate during those conditions, yet every unnecessary litre of potable water adds cost and competes with other users in a constrained system.

The goal is not to suggest that one packing line determines a river’s health. Local conditions vary, so saved water has the greatest value in places and seasons where supplies are tight. Fresh Del Monte’s wider approach to responsible water, biodiversity and community impact is documented through corporate sustainability reporting, which places the 30 percent packing result within our broader social and environmental commitments.

Measuring the water our process actually uses

First, we establish where water enters and leaves the process. Separate meters at incoming mains, wash stations, rinse points and cleaning systems reveal consumption by activity. We compare litres of make-up water with tonnes packed, rather than looking only at total facility consumption, so higher-volume shifts and different avocado varieties do not distort performance.

A defined pre-program baseline is then compared with metered results under normal operating conditions. Continuous-flow hoses, overlong rinsing and small leaks often become visible once teams review hourly data. The same records help managers distinguish genuine efficiency from changes caused by a softer crop, longer cleaning cycle or unusual heat.

Major grocers such as Coles and Woolworths, together with independent greengrocers, also place increasing emphasis on traceable sourcing and credible environmental claims. Clear litres-per-tonne reporting supports that expectation and gives buyers and site teams evidence that efficiency has not come from weaker cleaning or skipped hygiene steps.

Reusing water without compromising hygiene

Water recovery works only when streams are separated. Water carrying soil, wax or heavy soil is sent to an appropriate treatment or disposal route, while suitable final-rinse water can be collected for an earlier, less sensitive wash stage. This sequencing reduces fresh intake without sending the same water through every cleaning step, creating a controlled recirculation loop instead of indiscriminate reuse.

High-pressure, low-flow nozzles, leak-tight valves, variable-speed pumps and automated shut-offs address losses at the source. Validated brushing and dry-cleaning methods can replace unnecessary washing where the process permits, while recovered water may serve suitable floor cleaning or approved irrigation. In Queensland and Western Australia, rainwater can supplement supply in wetter months, but variable rainfall means it is not a dependable substitute for carefully managed reuse.

Implementation is staged so operational teams can verify each step. A small recovery loop may begin with a lower-risk application, while meters show whether the saving is sustained. Any change to water quality, chemical use or discharge must meet the site’s food-safety plan and applicable requirements from Australian water and environmental authorities.

Protecting quality while changing operating habits

Every reuse loop remains inside a food-safety framework. Teams verify turbidity, microbiological indicators, chemical concentrations and required sanitation limits at defined points, and they document each change to standard work. If a stream fails the approved specification, it leaves the reuse loop; the objective is efficient water use, not a blanket recycling policy.

Training makes the controls part of daily work rather than a one-off engineering project. Operators learn how to start and stop equipment in sequence, identify signs of blocked sprays or damaged seals, and respond correctly to interruptions. Maintenance teams inspect hoses, tanks, filters and meters on a schedule, while supervisors check that cleaning times, product handling and environmental conditions remain within validated limits.

Turning a 30 percent reduction into wider value

The 30 percent reduction in water used by the covered packing process lowers demand without reducing the care applied to the fruit. Less water for equivalent output can also mean less pumping, heating and treatment, helping lower energy use and operating costs. The result is reported as a packing-process improvement, not as a claim that every site, season or water source will perform identically.

That discipline extends to the wider supply chain. Australian households can reduce edible avocado waste by buying quantities that will ripen in time, using a paper bag to speed ripening and refrigerating ripe fruit when needed. Practical guidance in food education resources supports better everyday choices, while packhouse water efficiency ensures that resources used before sale are used more sparingly.

A practical model for Australian packing operations

Australia’s circular-economy policy direction reinforces this approach. The National Environment Protection (Used Packaging Materials) Measure 2025 and state-based extended producer responsibility schemes are increasing responsibility for packaging design and recovery. Although water conservation sits outside those rules, both priorities reward the same operational discipline: measure material flows, prevent waste and design out losses before adding more infrastructure.

Water efficiency also complements broader waste prevention. By documenting litres per tonne alongside packaging weight, spoilage and energy intensity, Australian sites can identify shared causes of loss and direct capital to improvements that lower several impacts at once. This makes water performance part of responsible operations rather than a stand-alone target.

The model works best when it is scaled from measured site needs. Facilities can begin with leak repairs and metering, map each water stream, and introduce recovery only after confirming hygiene requirements and local discharge rules. Training and shared litres-per-tonne targets then keep improvements in place. The practical takeaway is simple: meter every stage, recover only suitable water, and make validated reuse the default design choice where process and food-safety requirements allow.
