Some low-tech (and IMO better) solutions for food waste:

* Buy food locally, support your local farmers.

* Grow your own vegetables (some are really easy: potatos, onions, garlic, zucchini, corn, beans, etc.). Even tomatos, peppers and eggplants are not that hard.

* Compost your food waste - put it back in your garden.

* Learn how to preserve food when there's an abundance.

* Also, learn to eat better.

I think it's a real shame that so much food waste ends up in landfill instead of being composted locally. If you compost your leftovers, you turn your waste into a resource, and use that to fertilize your garden.
