Tom and Kate Chappell began making eco-friendly personal care products in the late ‘60s, when they were unable to find any on store shelves.  Taking out a $5,000 loan from a friend, they startedTom’s of Maine with ‘Clearlake’, the country’s first phosphate-free laundry detergent.  In 1975 they introduced the first natural toothpaste, which cemented their future as a leader in the natural personal care industry. Tom and Kate share in the $100 million fortune they made from selling Tom’s of Maine to Colgate in 2006, and remain the CEO and VP of the company, respectively.  Tom’s of Maine pulls in about $45 million in annual sales.

Of the green industry’s future, Tom told SFGate, “The current consciousness for environmental sustainability is different from anything I’ve ever seen before. It’s coming from industry, from companies, for the first time. You’ve had small companies doing a grassroots effort for decades, along with consumers and nonprofit groups, but now you’ve got large companies with senior leadership saying we’ve got to take this seriously. That’s terrific. We know that green solutions are possible. We just need to have green solutions become more available and affordable.”
