I see an opportunity.

The economic downturn has decimated the market for recycled materials like cardboard, plastic, newspaper and metals. Across the country, this junk is accumulating by the ton in the yards and warehouses of recycling contractors, which are unable to find buyers or are unwilling to sell at rock-bottom prices.

Ordinarily the material would be turned into products like car parts, book covers and boxes for electronics. But with the slump in the scrap market, a trickle is starting to head for landfills instead of a second life.

“It’s awful,” said Briana Sternberg, education and outreach coordinator for Sedona Recycles, a nonprofit group in Arizona that recently stopped taking certain types of cardboard, like old cereal, rice and pasta boxes. There is no market for these, and the organization’s quarter-acre yard is already packed fence to fence.

“Either it goes to landfill or it begins to cost us money,”

Unlike chicken manure, cardboard packing boxes have little worth as a soil amendment. But it might still be a useful feedstock for pyrolyzers in a CHP system. It seems a better idea than burying it in a land fill.

The precipitous drop in prices for recyclables makes the stock market’s performance seem almost enviable.

On the West Coast, for example, mixed paper is selling for $20 to $25 a ton, down from $105 in October, according to Official Board Markets, a newsletter that tracks paper prices. . .

The downturn offers some insight into the forces behind the recycling boom of recent years. Environmentally conscious consumers have been able to pat themselves on the back and feel good about sorting their recycling and putting it on the curb. But most recycling programs have been driven as much by raw economics as by activism.

Cities and their contractors made recycling easy in part because there was money to be made. Businesses, too — like grocery chains and other retailers — have profited by recycling thousands of tons of materials like cardboard each month.

But the drop in prices has made the profits shrink, or even disappear, undermining one rationale for recycling programs and their costly infrastructure.

I doubt that feedstock at $105 a ton would make sense for pyrolysis, but at #20 a ton it might pencil, and it would provide a fashionable rationale for recycling programs. Telling do-gooders that their efforts would sequester carbon might be powerful motivation.
