No, our eco-nappies are not 100% biodegradable. At this time no disposable nappy can claim to have zero environmental impact. We set out to create the most environmentally-friendly disposable nappy we possibly could without compromising on nappy performance or bottom comfort. We are also working with NappiCycle to keep disposable nappies out of landfill and put them into good use in affordable housing and notice boards for nurseries, schools and businesses
