When the baby gets older, the cloth diapers get more expensive. They trust cotton diapers more than disposables. Cotton has proved itself over a thousand years. Besides that, Debis claims that babies don't get diaper rash when they wear cloth napkins. Diaper services are not totally harmless to the environment, as no business is.
Trucks drive around to pick up the diapers.
Afterwards the diapers are dried in a dry-cleaner instead of in the sun or wind. Nevertheless it looks like re-usable diapers are friendlier to the environment than disposables. More energy and water is needed to manufacture disposable diapers than to produce and wash a cotton one. That is the conclusion of the New York Public Interest Research Group. Not to speak about the solid waste.
