Are Eco Nappies Better Than Disposables?

For new parents, the nappy aisle has become even more complicated than ever. Should you stick with conventional disposables, make the switch to eco-friendly nappies, or embrace reusables? Understanding the differences can help you make a confident, informed choice - and one that supports your baby’s wellbeing as well as your own values.

What’s the difference between disposable vs. eco vs. reusable nappies?

Disposable nappies are the most widely used and convenient option. However, they’re made using plastics, adhesives, and synthetic gels that can take up to 500 years to break down. They're also known to contain potentially harmful chemicals like chlorine, fragrances, and dyes that may irritate sensitive skin.

Eco nappies, also known as eco-disposables, aim to reduce that impact. They’re typically made with sustainably sourced, plant-based materials (our Kit & Kin nappies use FSC-certified pulp or corn starch) and avoid toxic ingredients. Many are free from chlorine, latex, fragrance, and lotions, making them a gentler choice for delicate skin.

Reusable nappies - often made from cotton, bamboo, or other natural fibres - are washable and designed for long-term use. They significantly reduce waste, especially when used across multiple children. Although they require a bit more commitment, modern reusable systems are far more user-friendly than they used to be.

Key benefits of eco nappies over standard disposables:

Use of renewable, biodegradable or compostable materials
Free from chlorine, latex, artificial fragrances, and bleaching agents
Reduced reliance on petroleum-based plastics
Often produced by ethical brands with transparent supply chains

The truth about biodegradable nappies: are they really eco-friendly?

It’s easy to assume that all biodegradable nappies are automatically better for the planet, but the reality is more nuanced. Understanding how biodegradability works can help you cut through the greenwashing.

What are biodegradable disposable nappies?

Biodegradable nappies include plant-based components that are designed to break down faster than traditional plastic-heavy nappies. This might mean the top sheet, core, or outer wrap is made from renewable resources like bamboo or bio-based polymers. Ours are plastic-free, meaning they significantly reduce plastic waste in landfills.

The biodegradation of eco-friendly nappies

Eco-friendly nappies are designed to break down more easily than traditional disposables, thanks to their use of renewable, plant-based materials and reduced plastic content. While not all components are fully compostable, many will degrade faster and with less environmental impact. Even when they don’t fully break down, they still avoid the toxic residues and persistent plastics found in conventional nappies - making them a smarter, cleaner choice for the future.

What happens to biodegradable disposables when they hit landfill?

Even in landfill conditions, where oxygen is limited, eco nappies still offer environmental benefits. Their lower plastic content and non-toxic ingredients mean they release fewer harmful substances over time. While full biodegradation might be limited in landfill, every nappy made with less plastic and fewer chemicals helps reduce the long-term burden on our planet. Choosing eco nappies is about making better choices step-by-step, rather than waiting for perfect solutions.

When can I start using reusable nappies with my baby?

You can start from day one, or ease into it once your baby grows out of the newborn phase. Many parents find success with a hybrid approach - using reusables at home and eco nappies when out and about. This flexibility helps reduce waste without adding too much pressure.

Ethical and eco nappies

Eco nappies aren’t just about what they’re made from, but how they’re made, and by whom.

Finding eco-friendly nappies

According to research by Ethical Consumer, not all eco nappies live up to their branding. They rated 20 nappy brands on environmental impact, labour practices, transparency, and use of harmful chemicals. The results show that some of the smaller, truly eco-focused brands outshine bigger names that only partially improve on traditional disposables.

At Kit & Kin, for example, we focus on sustainably harvested materials, reduced plastic content, and ethical manufacturing practices, while also helping protect rainforests through our World Land Trust partnership.

Final thoughts: making a more conscious choice for your baby and the planet

While no nappy is perfect, eco nappies offer a meaningful step in the right direction. By choosing nappies made from responsibly sourced materials, free from harsh chemicals, and designed with sustainability in mind, you're helping to reduce your family’s impact on the planet - one change at a time. Whether you go fully reusable, switch to eco-disposables, or mix and match, every eco-conscious choice matters. And when it comes to your baby’s comfort and future, that’s a decision worth making.
