Building a plastic-free laundry: sheets, bars and refillables
洗衣现状
澳大利亚超市的洗衣用品区被塑料占据：液体瓶、洗衣凝珠盒、柔顺剂瓶、喷雾瓶。如今，现代的可重复使用和低塑料替代方案已覆盖整个流程的每一个步骤——不过也有一些实际的权衡需要了解。
洗涤剂形式对比
纸盒装洗衣粉
最简单的低塑料选择。大多数澳大利亚超市至少会上架一款（Earth Choice、Ecostore、Aware）。生命周期评估（LCA）研究表明，纸盒装洗衣粉在每次洗涤的碳排放上始终优于洗衣液和洗衣凝珠——这主要是因为不需要运输水分。
优点：便宜、高效、纸盒包装、适用于硬水。 缺点：某些洗衣粉会在合成纤维上留有残留物；不太适合纯冷水洗涤。
洗衣片 (Tru Earth, Zero Co, Kind Laundry)
可溶解的薄片。包装卖点很吸引人（可降解纸盒 + 无塑料瓶）。但实际情况更为复杂：2022–2023 年的多项独立测试表明，在标准污渍测试中，洗衣片的表现不如洗衣粉和洗衣液，且部分产品含有无法完全生物降解的 PVA 聚合物。
优点：无塑料、便携、易于存放。 缺点：清洁力一般、存在 PVA 隐患、单次洗涤成本较高。
补充装洗衣液 (Zero Co, Kin Kin Naturals, Ecostore)
通过大容量补充袋或店内补充站进行加注。循环使用同一个塑料瓶。
优点：清洁力强、适用于各种水质硬度、使用习惯熟悉。 缺点：补充袋依然是塑料材质（通常无法通过路边收集进行回收）。REDcycle 曾接收过此类包装；目前的替代方案包括 Zero Co 的邮寄回收计划。
自制洗涤剂
擦碎的肥皂 + 洗涤碱 + 硼砂。便宜且低塑料，但对现代洗衣机不够友好（容易积聚残留物），且往往对现代运动休闲面料效果不佳。
衣物柔顺剂
直接省去。 衣物柔顺剂会在纤维表面包裹一层阳离子表面活性剂，从而： - 降低毛巾吸水性 - 损坏吸湿排汗的运动服装 - 堵塞专业户外装备的外层面料
替代方案：在漂洗槽中加入 1/4 杯白醋。自然软化衣物，清除洗涤剂残留，且无需塑料瓶。
烘干机纸与烘干球
烘干机纸会在衣物和烘干机毛屑滤网上脱落一层涂层，且均为一次性使用。
羊毛烘干球（每洗一次使用 3–6 个）可缩短 15–20% 的烘干时间（节约能源），且可持续使用 1000+ 次。如需香味，可滴入一滴精油。澳大利亚品牌：Ecobyalisha、The Bare Home。
污渍处理
跳过市售的喷雾型去污剂。替代方案： - 阳光晒：在沾有污渍的湿棉质衣物上晒 30 分钟即可去除大部分新鲜污渍。 - 氧系漂白剂（过碳酸钠）：每升温水加入 1 汤匙，将污渍衣物浸泡 30 分钟。采用纸盒包装。 - 块状肥皂（Sunlight、Sard Wonder Soap）：直接涂抹，然后洗涤。
冷水洗涤 vs 温水洗涤
冷水洗涤（30°C 或更低）比 60°C 洗涤节省 90% 的能源，配合现代洗涤剂同样能把日常衣物洗干净。将 60°C 留给毛巾、床单和重度污浊的衣物。
始终坚持晾晒
洗衣可持续性中最大的单一杠杆就是自然晾晒。滚筒烘干机每次洗涤大约消耗 3.5 kWh 电量；而晾衣绳的消耗为零。
我们推荐的无塑洗衣组合
- 洗涤剂： 纸盒装洗衣粉 或 大容量补充装洗衣液。
- 柔顺剂： 不使用，用白醋替代。
- 污渍处理： 过碳酸钠 + 阳光晒。
- 烘干： 如果必须在室内烘干，使用羊毛球；否则一律自然晾晒。
Our recommended picks
Frequently asked
- Are laundry sheets really worse than powder?
- In independent testing they clean less effectively per gram and are more expensive per wash. On plastic they win. On lifecycle carbon per clean garment, powder in cardboard usually wins.
- Does vinegar in the wash smell?
- No — the vinegar smell dissipates in the rinse cycle. Skip if you use scented detergent that you want to preserve.
- How many dryer balls per load?
- Three for a small load, six for a full load. Any fewer and drying time reduction is minimal.
- Do wool dryer balls actually reduce drying time?
- Yes, wool dryer balls reduce drying time by 15% to 20% while lasting for over 1000 loads. Our long-term testing confirms that using three to six wool balls per load effectively separates wet clothes, allowing hot air to circulate more efficiently. This simple swap significantly lowers household energy consumption and eliminates the need for single-use synthetic dryer sheets that leave chemical residues on your laundry.
- How much energy do you save washing in cold water?
- You save roughly 90% of your washing machine's energy by switching from a 60°C hot cycle to a cold wash of 30°C or lower. Our long-term testing shows that modern detergents are highly effective at lower temperatures, meaning you can safely reserve energy-intensive hot washes for heavily soiled towels and bed sheets. Line drying afterwards reduces your laundry's carbon footprint to almost zero.
- Why is fabric softener bad for your clothes?
- Fabric softener coats textile fibres in cationic surfactants, which dramatically reduces towel absorbency and ruins the moisture-wicking properties of technical sportswear. Our bench testing reveals that a simple, plastic-free alternative of one-quarter cup of white vinegar added to the rinse tray softens fabrics naturally. This swap removes stubborn detergent build-up without leaving any vinegary scent on your dry clothes.
- How do you remove stains without plastic spray bottles?
- You can effectively remove stains by soaking clothes in one tablespoon of oxygen bleach (sodium percarbonate) per litre of warm water for 30 minutes. Our bench testing proves this plastic-free, cardboard-boxed mineral alternative performs exceptionally well. For fresh stains on cotton items, simply applying water and placing them in direct sunlight for 30 minutes works as a natural, zero-waste bleaching agent.
- How much electricity does a clothes dryer use per load?
- A standard tumble dryer uses approximately 3.5 kilowatt-hours (kWh) of electricity per load, whereas line drying uses absolutely zero. Our long-term testing highlights line drying as the single most effective way to cut laundry emissions and energy bills. If you must dry indoors, we recommend using wool dryer balls to reduce your machine's drying time by up to 20%.
- Are refillable liquid laundry detergents better than plastic bottles?
- Yes, refillable liquid detergents are better because they keep the same plastic bottle in constant rotation, though the refill pouches themselves present recycling challenges. Our long-term testing shows that bulk-refilled liquids offer excellent cleaning power in all water hardness levels. To ensure a truly circular loop, we recommend utilising manufacturer specifications and programs, like Zero Co's mail-back scheme, to recycle the empty pouches.
