Question: Which schools have recycling bins for newspapers, glass and plastic bottles? Last month several were closed. Are there any left on Oahu?

Answer: No.

There used to be a link to bin locations on the city Department of Environmental Services’ website, opala.org.

However, about three weeks ago Honolulu Recovery Systems, which took over management of this recycling program from the city two years ago, removed all remaining bins from the schools, said Markus Owens, spokesman for Environmental Services.

Residents are now directed to drop off mixed recyclables at one of the HI-5 redemption centers around the island that are accepting other recyclables, in addition to deposit beverage containers.

These "HI-5 Plus — One-Stop Recycling Centers" are listed on the city’s website: www.opala.org/solid_waste/HI5_plus.html.

In the heyday of the community recycling bins, the city had more than 100 locations, Owens said.

"But with the implementation of islandwide curbside recycling, this program saw a greater than 75 percent reduction in recovered materials from these bins," he said. "Significant reductions in bin use led to higher hauling and processing costs, to the point where the program became too costly to maintain."

In 2012 the program was shifted to Honolulu Recovery Systems.

By October of that year, the number of bins was down to 35, with many schools opting out because of diminishing returns and maintenance problems.

Honolulu Recovery Systems told Kokua Line it would continue to offer the program as long as it could break even on costs, which was not happening. (See bit.ly/1fR4B2V and bit.ly/1shsjad.)

Because of reduced bin use and rising costs, Owens said the company decided to discontinue the program altogether.
