At first glance, you might think the city of Boston getting into the curbside composting business would be terrible for scrappy, JP-based Bootstrap Compost. But that's not how Andy Brooks, founder and president of the three-year-old composting company, sees it. "It's not like Marty Walsh is going to be on his bike picking stuff up," Brooks said in a Friday phone interview. Being on the bike picking stuff up is what Brooks and now five employees have been pioneering. Clients get an unmistakeable white "Bootstrap Compost" bucket for their organic waste.
