The city of Allentown, Pa., has expanded its curbside recycling program to include cartons.

Residents now can add milk, juice, broth, soup and similar cartons to their recycling bins, the city said in a news release.  Cartons also are now being accepted at the city’s drop-off center.

The city expanded the program with the help of the Vernon Hills, Ill.-based Carton Council and Houston-based Greenstar LLC, which processes and markets the city’s recycled cartons, cans and bottles.

 “Our residents recycled 3,600 tons of cans and bottles last year,” said Mayor Ed Pawlowski. “The city has been a leader in recycling and now we are proud to add cartons to the mix.”

Allentown’s recycling programs reach 36,500 households and 475 businesses in its weekly curbside collection program.
