We Test New Packaging Materials for Home Compostability

Australia has one of the most active household composting cultures in the world, and that shapes how we evaluate every new package before it reaches a customer. In suburbs from Brisbane to Adelaide, kerbside Food Organics and Garden Organics (FOGO) bins now sit beside general waste, and many homes keep a backyard tumbler or worm farm running year round. That everyday habit pushes us to move beyond the international industrial standard and focus on whether a material will truly break down in a real Australian compost heap.

For Fresh Del Monte Produce, home compostability is not just a checkbox on a procurement form. It is a public commitment tied to the National Plastics Plan and to state level rules such as Western Australia's phase out of lightweight plastic produce bags. Because Australian conditions can be dry, hot, or cool depending on the region, our testing has to reflect what happens on a kitchen bench, in a small backyard bin, and through a council pickup.

Why Australian Household Composting Demands Specific Testing

A backyard compost bin in Melbourne behaves very differently from an industrial facility in Europe. Temperatures rarely climb above 45°C, moisture fluctuates with the seasons, and the mix of food scraps, lawn clippings, and prunings is far less controlled than what a commercial facility manages. We design our trials around these everyday realities so that a package labelled home compostable truly disappears within twelve to twenty four months in a domestic bin.

Australian households also generate a distinctive mix of organic waste. Avocado skins, mango pips, and pineapple tops are routine additions to kerbside FOGO caddies in cities like Sydney and Brisbane, which is why our research partnerships with local councils and waste educators are so important. We want to see how a bioplastic mesh bag or a kraft tray interacts with the fibrous, acidic, and often nitrogen rich streams typical of an Australian kitchen.

Lab Screening Against Australian and International Standards

The first pass for any new material happens in accredited laboratories across Australia and overseas. We measure carbon conversion under AS 5810 for home compostability, alongside EN 13432 and ASTM D6400 for industrial systems, which lets us compare performance across the full spectrum of disposal pathways. Each sample spends weeks in controlled reactors where oxygen uptake, carbon dioxide release, and temperature are tracked against reference materials.

Disintegration is measured by sieving the compost and weighing any fragments larger than two millimetres, while ecotoxicity is checked by planting cress and exposing earthworms to the finished compost. Heavy metals, microplastic residues, and fluoride are also screened to meet the Australasian Bioplastics Association's guidance. A material that passes these screens moves on to real world trials, but only after our agronomists confirm that the finished compost will not harm soil biology.

Backyard Trials from Sydney to Perth

Lab data tells part of the story, yet nothing replaces a long, slow season in someone's actual garden. We coordinate home trials with volunteer households in suburbs such as Marrickville, Fremantle, Hobart's Sandy Bay, and the inner north of Brisbane. Volunteers place labelled samples of our packaging into their home bins, worm farms, or trench composting systems and log temperature, moisture, and visible breakdown every fortnight.

After roughly six months, the samples are collected and sent back to our partner laboratories for final analysis. Findings on the role of cover crops in erosion control on sloped pineapple fields shaped the way we think about soil biology and organic matter cycling, and the same curiosity about living systems drives these household trials. The goal is to see how microbial communities in different Australian climates treat the material, from the humid subtropics of Queensland to the dry summers of Perth.

Comparing Home Bins With Municipal Commercial Composting

Not every Australian council operates the same way. The City of Sydney sends FOGO to a covered in vessel facility that reaches 60°C, while some regional councils in Victoria still rely on open windrows or small tumbler systems that stay cooler. We test our packaging in both kinds of programs to ensure that a material designed for home compostability does not fall apart prematurely in a commercial facility, or stubbornly linger in a backyard bin.

The table below summarises how a typical home compostable film performs across the four pathways most relevant to Australian consumers. It is drawn from a recent internal round of testing and reflects average values from multiple samples, rather than a guarantee for any single household setup.

These results help our packaging team choose materials that are forgiving across the real mix of systems Australian shoppers actually use, rather than optimising only for the easiest disposal route.

Sharing Results Across Our Growing Regions

Reporting is where the discipline of testing pays off. Each quarter we publish findings through internal briefings, supplier scorecards, and our public sustainability platform, so that growers in Costa Rica, Kenya, and the Philippines can see how a chosen film, tray, or mesh sleeve performs in a Queensland compost bin or a Western Australian worm farm. Transparency also gives our retail partners in Coles, Woolworths, and Harris Farm the confidence to communicate clearly with shoppers.

Budgeting for this kind of long horizon research is its own kind of craft, much like disciplined resource management in other high stakes settings. Every trial costs time, lab fees, and volunteer coordination, so we stage investments carefully and reallocate funds when early results suggest a material will not meet our compostability bar. The result is a programme that protects both the science and the communities that depend on honest packaging claims.

Our growing commitment to home compostability will keep pushing us toward materials that disappear cleanly into the same soil that grew the fruit inside. The next package you pick up at a Brisbane market stall or a Perth supermarket should reflect years of backyard trials, lab screens, and honest reporting, all aimed at closing the loop from farm to fork and back to the earth.
