Nothing says “successful party” like a huge overflowing trash can full of paper plates and plastic cups. But ugh, so much waste. Brooklyn performance artist Emily Doubilet took this on as problem she could solve with a new business with a conscience. Her “Susty Party” products are eco-friendly, colorful and manufactured in the U.S. by an Ohio non-profit that employs visually impaired people. She’s one of five $40,000 winners of the Hitachi Foundation’s Yoshiyama Young Entrepreneurs Program this year.
