IRVING PARK — When it comes to recycling, Chicago has a contamination problem.

In plain English, too much trash is getting tossed into recycling containers, spoiling even the best of intentions.

The Chicago Sustainability Leaders Network, in conjunction with city agencies, is hosting a series of meetings to clarify what is and isn't recyclable, identify the biggest hurdles to recycling correctly, and to brainstorm ideas that could make the program more successful.

The last of these forums is scheduled for 6-8 p.m., Wednesday, at Horner Park, 2741 W. Montrose Ave.

An RSVP is requested but not required.

Among the top contaminants:

• Pizza boxes, pizza boxes, pizza boxes. The grease is the culprit here. Either put the entire box in the garbage or tear off the greasy part before recycling.

• Shredded paper. It clogs recycling machinery and causes the equipment to break down.

• Coffee cups. The waxy lining is not recyclable.

• No. 6 plastic. It doesn't matter that there's a recycling symbol on these items — recycling facilities don't accept them.

• Electronics. Yes, they're made of metal and plastic but no, they're not blue bin material.
