If you're concerned about the chlorine and dyes in traditional feminine-hygiene products, not to mention the waste tampons and pads generate—7 billion tampons and 15 billion pads end up in U.S. landfills each year—try these alternatives.

The DivaCup. This reusable 1-ounce silicone cup catches menstrual flow and can be inserted for up to 12 hours at a time. Empty two to four times a day.

GladRags. Made with terry cloth and cotton flannel wings that snap around underwear, GladRags washable pads come in three absorbencies—daytime, nighttime, and panty liners.

Jade and Pearl Sea Pearls. Reuse these soft, sustainably harvested sea-sponge tampons for up to six months. Sponges must be removed and washed with mild soap every 3-4 hours for maximum protection.

Natracare Organic All Cotton Tampons. Available with an applicator or without, Natracare products are biodegradable and free of pesticides, chlorine, dyes, and perfumes.

Seventh Generation Chlorine Free Pads. Women with sensitive skin will love Seventh Gen's wheat-based, chlorine- and fragrance-free maxis.
