About Eco LunchBox
ECOlunchbox was born of the idea that change can begin at lunchtime. I wanted to make a change in how I packed my family’s lunches – to cut out the plastic and do the right thing for our health as well as Mother Earth. It seemed like a pretty simple concept. Design a food container out of something plastic-free and make it available to friends, family and through an online store. Since founding ECOlunchbox as a triple-bottom-line social enterprise in 2009, the business has scaled beyond my initial vision.
