Americans love convenient recycling, but convenient recycling increasingly does not love us. Waste experts call the system of dumping all the recyclables into one bin “single-stream recycling.” It’s popular. But the cost-benefit math of it has changed. The benefit — more participation and thus more material put forward for recycling — may have been overtaken by the cost — unrecyclable recyclables. On average, about 25 percent of the stuff we try to recycle is too contaminated to go anywhere but the landfill, according to the National Waste and Recycling Association, a trade group. Just a decade ago, the contamination rate was closer to 7 percent, according to the association. And that problem has only compounded in the last year, as China stopped importing “dirty” recyclable material that, in many cases, has found no other buyer.
