Poor Maria and her left over lunch. She hated throwing out those apple cores, teabags and napkins in the trash for landfill when they’re just perfect for a compost heap. Turns out a few of her buddies felt the same way, so they contacted us here at Energy & Environment ( and got a green bin for their lunchroom. They take turns taking it to the central compost collection, and Maria masters the schedule. So no one forgets their turn, or they risk inciting the wrath of Maria! Not that it would ever happen. Composting is a great way to turn leftovers into lunch for new crops and plants, and a rind is a terrible thing to waste (groan).
