NEW YORK—City sanitation experts confirmed yesterday that the supposed “recycling” of Manhattan resident Ron Klauff was in fact a conglomeration of various recyclable and nonrecyclable refuse that takes city workers an average of two hours and 288 gallons of water to sort and clean each week. “These days, being eco-aware is more important than ever,” said Klauff, filling a plastic shopping bag with a mixture of yogurt containers, wire hangers, and broken electronics that a civil servant will later have to sift through in the middle of the night. “You have to do your part, even if that means gathering all of your soda cans and stacking them neatly inside your pizza boxes.” Because Klauff is the only New York resident who does not carefully sort and separate his recyclables, officials are considering just tossing everything he throws out into a landfill.
