It’s easy being green with a subscription to Bootstrap Compost, a Boston-based service that’s diverted nearly two million pounds of waste from landfills. A 5-gallon bucket is delivered to your door for you t o fill with everything from coffee grounds to vegetable scraps. Then Bootstrap picks it up and returns a portion of the cured compost to your home or office. Not a gardener? You can opt to donate your returns to community garden projects in Jamaica Plain and Roxbury, really turning one man’s trash into another man’s treasure.
