How to Recycle Plastic Food Storage Containers, Lids And Tubs

Plastic food storage containers are useful, lightweight and common in Australian kitchens, but recycling them is less straightforward than placing every item with a recycling symbol into the yellow-lid bin. Different councils accept different types of plastic, and the rules can vary between suburbs, apartment buildings and regional areas. A tub that is accepted in Melbourne may be handled differently in Brisbane or regional New South Wales.

The best approach is to identify the material, remove food residue, keep recyclable pieces loose and follow your local council’s instructions. Lids and tubs should be considered separately because their shapes, sizes and plastic types may differ. With a few practical habits, you can reduce contamination and keep reusable containers in service for longer.

Identify The Container And Its Material

Most food storage tubs are made from rigid plastic, commonly polypropylene marked with the number 5 recycling code or high-density polyethylene marked with number 2. Some clear containers use polyethylene terephthalate, or PET, while others are made from mixed plastics that are difficult to sort. The number inside the triangle identifies the resin type; it does not automatically mean your council accepts the item in kerbside recycling.

Look for a recycling symbol, manufacturer information or council guidance, but do not rely on the symbol alone. A rigid, empty yoghurt tub may be accepted while a black plastic takeaway tray, compostable-looking container or flexible pouch may not be. Black plastic can be difficult for optical sorting equipment to detect, and some products combine several materials that cannot be separated economically.

Size and shape also matter. Very small lids, loose caps and broken fragments can fall through sorting machinery or become contaminants. Large, rigid tubs are usually easier to identify and process, provided they are clean and dry. If an item is tiny, heavily damaged or made from several bonded materials, check with the council or recycling facility before adding it to the yellow bin.

Australia’s recycling system is managed locally, so residents in Sydney, Melbourne, Perth and smaller regional centres may receive different instructions. The Australian Recycling Label on newer packaging can help, but it should be read alongside your council’s current collection rules.

Prepare Tubs Before They Reach The Bin

Empty every container completely and scrape out food before rinsing. A quick rinse is generally enough; you do not need to use hot water or spend several minutes making a container look spotless. The goal is to remove sauces, oils, dairy residue and crumbs that could contaminate paper and cardboard during collection and processing.

Allow the tub to drain and dry. Wet containers can cause paper fibres to stick to plastic, while leftover food attracts pests and creates unpleasant odours in household bins. If a container held curry, peanut butter or oily dressing, use a small amount of dishwashing liquid and warm water, then leave it upside down to dry. Avoid putting a container into recycling while it is still full of liquid.

Separate removable labels, foam inserts and non-plastic parts where your council directs you to do so. A paper label that remains firmly attached is usually not a reason to discard an otherwise recyclable tub, but metal clips, silicone seals and fabric sleeves may need another disposal route. Do not place a container inside another container, as sorting equipment may not detect the item hidden inside.

Lids need particular care. Some Australian councils ask residents to leave lids on bottles but remove them from tubs; others accept both parts together if they are larger than a specified minimum size. If your council accepts plastic lids, replace the lid on its tub where practical or place both pieces loose in the recycling bin. Never put lids inside tubs, bags or cardboard boxes.

Check Your Council’s Accepted Items

Before recycling plastic food containers, search your local council website for “rigid plastic”, “plastic tubs” or “kerbside recycling”. The accepted list should tell you whether takeaway containers, yoghurt pots, lids, black plastic, microwave trays and damaged items are included. If the information is unclear, contact the council waste team or ask the operator at your local transfer station.

Rules can change when contracts, sorting facilities or state programs change. Soft-plastic collection is a good example: after the collapse of the REDcycle scheme in 2022, many households had to stop taking bread bags, cling film and snack wrappers to supermarket drop-off points. Some councils and retailers now offer limited collection trials, but these services are not universal. Keep soft plastic out of the yellow-lid bin unless your council specifically says otherwise.

Container deposit schemes also operate differently across the country. NSW residents can use Return and Earn, Queensland residents may use Containers for Change, and Victoria has its own container deposit scheme. These programs mainly cover eligible drink containers rather than ordinary food storage tubs, yet they illustrate why local instructions matter. A drink bottle may earn a deposit at a collection point while a similar-looking food container belongs elsewhere.

When in doubt, keep the uncertain item out of the recycling bin until you have checked. A small amount of incorrect plastic can create more work at the sorting plant and may cause clean paper, cardboard or metal to be rejected.

Reuse Good Containers Before Recycling

Recycling is valuable, but extending the useful life of a sturdy container usually avoids the need for new material and manufacturing. Keep tubs that still have secure lids, stable bases and no strong odour. They can hold leftovers, lunchbox snacks, pantry ingredients, screws, craft supplies or seedlings. Mark the date on stored food and follow safe refrigeration and reheating practices.

Do not continue using plastic that is cracked, warped, brittle, deeply scratched or stained with a persistent chemical smell. Damaged containers may leak, harbour residue or fail when heated. Unless the manufacturer says a container is microwave-safe, transfer food to glass or ceramic before reheating. Takeaway tubs are often designed for short-term use rather than repeated heating and washing.

A container without a lid can still have a second life. Use it to organise a drawer, collect paintbrushes during a project or store garden ties. A lid without its matching tub may be useful as a drip tray, palette or small plant saucer, although sharp edges and food-contact limitations should be considered. When an item can no longer be reused, sort it according to the local recycling instructions rather than automatically sending it to landfill.

Reducing food waste also makes container recycling easier. A well-planned meal schedule means fewer forgotten leftovers and less dried-on food to scrub away. Households interested in keeping organic scraps out of landfill can pair their storage routine with this backyard compost guide, adapting the method to Australia’s climate, local composting rules and available outdoor space.

Build A Reliable Kitchen Sorting Routine

A consistent routine prevents rushed decisions on bin night. Keep a small area near the sink for containers that need emptying, rinsing or drying. Once dry, check each tub and lid against the council list. Place accepted rigid plastics loose in the recycling bin, and put rejected materials into the correct rubbish, drop-off or special collection stream.

For households in flats or units, confirm whether the building uses a private waste contractor rather than the council’s standard service. Shared recycling rooms often contain contamination from well-meaning residents who follow rules from another suburb. A printed reminder near the bin can help, but it should reflect the building’s actual contractor instructions rather than a generic internet list.

Use the following routine for ordinary household tubs and lids:

• Empty all food, scrape away residue and rinse lightly.
• Let each piece drain and dry before sorting.
• Check the tub and lid separately for material, size and condition.
• Follow your local council’s rules for rigid plastics and loose lids.
• Keep soft plastic, polystyrene, compostable packaging and uncertain items out of the yellow-lid bin unless a named program accepts them.
• Reuse sound containers first, then use an approved drop-off or disposal option for items that cannot go in kerbside recycling.

Keep a note of your council’s recycling webpage on your phone, particularly if you move between a home, workplace and holiday property. Australian waste services can differ even between neighbouring councils, and regional residents may have fewer collection options than people near a major metropolitan sorting facility.

Community recycling centres can also provide practical education about materials, contamination and waste reduction. The S.A.F.E. Recycling Center offers information about recycling, environmental learning and community participation that can help households think beyond the yellow-lid bin. Local Australian councils, transfer stations and reuse groups can provide equivalent advice for residents closer to home.
