Building a plastic-free laundry: sheets, bars and refillables

The laundry landscape

Australian laundry aisles are dominated by plastic: liquid bottles, pod tubs, softener bottles, spray bottles. Modern reusable and low-plastic alternatives now cover every step of the process — with genuine trade-offs to understand.

Detergent formats compared

Powder in a cardboard box

Simplest low-plastic option. Most Australian supermarkets stock at least one (Earth Choice, Ecostore, Aware). LCA studies show powder in cardboard consistently beats liquid and pods on carbon per wash — mostly because no water is being shipped around.

Pros: cheap, effective, boxed in cardboard, works in hard water. Cons: some powders leave residue on synthetics; not great for cold-only wash.

Detergent sheets (Tru Earth, Zero Co, Kind Laundry)

Dissolvable strips. Attractive packaging story (compostable card + no plastic bottle). Real story is muddier: several 2022–2023 independent tests showed sheets underperform powder and liquid on standard soiling tests, and some contain PVA polymers that don't fully biodegrade.

Pros: no plastic, easy to travel with, easy to store. Cons: mediocre cleaning power, PVA concerns, more expensive per wash.

Liquid detergent refills (Zero Co, Kin Kin Naturals, Ecostore)

Refill from a bulk pouch or in-store refill station. Keeps the same plastic bottle in rotation.

Pros: strong cleaning, works in every water hardness, familiar workflow. Cons: refill pouches still plastic (usually not recyclable kerbside). REDcycle used to accept them; alternatives are Zero Co's mail-back program.

Homemade

Grated soap + washing soda + borax. Cheap and low-plastic, but rough on modern washing machines (residue buildup) and often ineffective on modern athleisure fabrics.

Fabric softener

Skip it. Fabric softeners coat fibres in cationic surfactants that: - Reduce towel absorbency - Damage moisture-wicking sportswear - Clog the outer fabric of technical outdoor gear

Substitute: 1/4 cup white vinegar in the rinse tray. Softens naturally, removes detergent residue, no plastic bottle.

Dryer sheets and dryer balls

Dryer sheets shed a coating onto clothes and dryer lint filter, and each is single-use.

Wool dryer balls (3–6 balls per load) reduce drying time by 15–20% (energy saving) and last for 1000+ loads. Add a drop of essential oil for scent if desired. Australian brands: Ecobyalisha, The Bare Home.

Stain treatment

Skip commercial spray-on stain removers. Alternatives: - Sunlight: 30 minutes on a wet stained cotton item removes most fresh stains. - Oxygen bleach (sodium percarbonate): 1 tbsp per L warm water, soak stained items for 30 min. Cardboard packaging. - Bar soap (Sunlight, Sard Wonder Soap): direct application, then wash.

Cold vs warm wash

Cold washing (30°C or lower) uses 90% less energy than a 60°C wash and cleans everyday clothes just as well with a modern detergent. Save 60°C for towels, sheets, and heavily soiled loads.

Line dry, always

The single biggest laundry sustainability lever is line drying. A tumble dryer uses roughly 3.5 kWh per load; a clothesline uses zero.

The plastic-free laundry stack we recommend

• Detergent: powder in cardboard OR bulk-refilled liquid.
• Softener: none, replaced with vinegar.
• Stain treatment: sodium percarbonate + sunlight.
• Dryer: wool balls if you must dry indoors; otherwise line-dry.
