I've mention a couple of times that we've switched to a mix of reusable and disposable nappies for practical reasons. While I believe the former are more eco-friendly, you need access to a washing machine & somewhere to dry them. So if you do go disposable, what are the choices?
Moltex (right) claim to be the only eco disposable nappy with an unbleached cellulose core. They are produced from 50% renewable resources, are 100% chlorine free and made with 20% biodegradable absorbent granules in the core. The outer film and the packaging are 100% biodegradable
Nature Care (left) are apparently made from 100% GM-free natural maize film and have a unique channel construction which reduces the volume of super absorbents by 50%. They got the Mother&Baby Silver Award for Best Disposable Nappy for 2006/7.
It's very difficult to choose between them on eco-grounds - both are chlorine free, have mainly natural materials and are almost totally biodegradable - what is not biodegradable is the absorbent gel which allows them to compete with their conventional equivalents.
So which to choose? We use Moltex for one very, very good reason. Whether it's the shape of the wee fella's bottom or not I don't know, but we've found the Nature Care nappies have let us down several times on the 'containment' front. Makes the decision very simple, I can assure you!
