Every year, about 450 million plastic toothbrushes make their way to landfills across the country. Most of them will never biodegrade, remaining in the ground for decades.

World Centric has unveiled a line of compostable toothbrushes and travel cases that are made from plant-based resin called Inego. The World Centric toothbrush is designed to full compost within 3-6 months when sent to a commercial composting facility.

The brushes sell for $4.55 and are available at natural grocery stores, some Whole Foods stores nationwide and at worldcentric.org.

Fifty million disposable diapers end up in land fills each year, and until recently, cloth diapers have been the only alternative. Unfortunately, many parents find cloth diapers to be messy and inconvenient.

gDiapers are available at Ozark Natural Foods in Fayetteville and online at gdiapers.com.
