Having read an interview of a zero-waste mom by another OpenIDEO-er, it would be remiss of not to mention Lauren Singer, a New York-based entrepreneur and zero-waste guru - whose waste for the past 4-years fits into a mason jar.
You can check out this video as she discusses the scenarios in her daily life that generates waste:
Her platform, Trash is for Tosser, hosts a collection of her talks, zero-waste lifestyle advice, and her organic, vegan cleaning products. I love how observant she is when evaluating where waste is generated (e.g. she noted that laundry labels on your (otherwise natural cotton) clothes are non-recyclable and that even pre-owned fashion items come with a plastic tag).
For newcomers, I'd say this is a pretty good place to get started in going zero-waste. Her "2 Steps to Zero Waste" advice is quite neat in describing the questions you should ask yourself and small steps you can take to make to reducing your waste, today.
