How long does it take to decompose diapers?

It varies based on company, materials and what it is composted with. Most recent estimates say 200-500 years.

For those interested in not filling up our landfills, gDiapers makes a hybrid diaper with a disposable liner: http://www.gdiapers.com/happy-planet

You can flush or compost the liner for very speedy results, or you can even toss it -- these decompose in just 2-6 months!

For an even better choice, FuzziBunz makes a completely re-useable diaper. No landfill waste at all:
