From the choice study- I find this info a little outdated, it was written in 2003.
:
For years there?s been an ongoing debate over which type of nappy has the least impact on the environment. While it might seem clearcut that reusable cloth nappies would be a more environmentally friendly option than disposables, in fact there are environmental costs associated with using both.
Many conflicting studies have been published, but unfortunately not many independent ones. Most research has been funded or sponsored by a company or organisation with a barrow to push, be it disposable nappy companies or environmental groups
I have read many conflicting studies- i guess this is the reason why. I have read some that says there is no difference, and i have a so read alot that suggests cloth is more environmentally friendly. I am more inclined to think that the studies showing cloth has less environmental impact are closer to the truth, as the big disposable manufacturers have alot to loose.
:
It takes more raw materials to make disposables than cloth nappies. They also have an obvious impact on waste disposal and landfill ? in 1999 it was estimated that using an average of six nappies a day over two and a half years produces about 734kg of solid waste. Multiply that by the number of disposable-wearing babies born in Australia each year and that?s a lot of disposable nappies taking up space in landfill.
For just one baby you?re talking about roughly 8000 nappies. And while it?s possible the weight of the disposables themselves may have decreased, the number of people using them has increased.
Parts of a disposable nappy are potentially biodegradable, but whether they do biodegrade and how long it takes will depend on the type of landfill, and whether bacteria needed for decomposition have access to air, water and light.
Cloth nappies also have an environmental cost. Growing cotton requires the use of pesticides and water, although new strains of genetically modified cotton claim to reduce the use of chemicals.
Like someone else pointed out most MCN are made from bamboo and hemp these days, so a little outdated.

However, the most significant environmental impact of cloth nappies occurs during their use, rather than production or disposal. Washing and cleaning them requires water and energy that you don?t use with disposable. You can minimise this by using cold water to wash and by drying on the line.
Unfortunately the expensive option of nappy services is probably the best from an environmental perspective, due to economies of scale. As a cheaper alternative and environmental compromise, you might consider using cloth nappies at home and disposables when you?re out.
The other thing to consider is that if you do chose cloth you get a choice in your environmental impact, (washing in cold, using sustainable unbleached fabrics etc.) whereas if you use sposies, there isn't much you can do.
I chose cloth b/c it sits better with me, but i certainly don't judge people for using disposables. Whatever works for you. I have an article form ozclothnappies, not sure if i can post a link to there so will pm you. Good luck with your reseach. ;)
