Ashes to ashes: The cycle of life returns human bodies to the soil, where they decompose and eventually return to new life as a tulip or perhaps as an apple (unless they've been embalmed, but that's another story).

That life cycle can also be true for banana peels, coffee grounds, and wilting flowers — if consumers don't toss them into the landfill where they'll get mixed together with plastics and other toxins, thereby rendering them useless to future generations.

This week, join host Jerry Kay, publisher of the Environmental News Network, to learn how San Francisco's composting program is bringing new life to old food.

This week's featured guests include Robert Reed of Norcal Waste Systems, Chis Simas of Capay Fruits and Vegetables, Mark Houser of Alexander Valley Vinyards, and Nigel Walker of Eatwell Farm.
