Nobody makes eco-disposable diapers in the U.S. — Seventh Generation diapers come close, but according to a company representative, they are not fully biodegradable. The trouble is the outer liner of disposables is always some kind of plastic. The only commercially available, fully biodegradable, disposable diaper is the Swedish "Nature Boy & Girl" diaper which, instead of a using plastic liner, uses a GM free corn starch-based film. This means the diapers are compostable — they are sold online at Nurture Center.
Moltex are bleach free, with no lotions, perfumes or deodorants, and Tushies are a gel-free disposable with a cotton and wood pulp padding of high natural absorbency and again, no perfumes or lotions. Bambo is the new and more affordable eco-disposable diaper (pictured here) — a pack of 30 costs about £4.59 ($8.60). Bambo diapers have a starch based absorbent core (less gel), they are oxygen bleached, free from lotions and perfumes, have latex free waist band and cuffs, and have a Nordic Swan eco certification. They are available from Beaming Baby.
