Connecticut’s recycling program is in trouble and those problems are already costing local taxpayers hundreds of thousands of dollars.

One of the troubles is that residents continue to attempt to recycle things that shouldn’t be put in recycling bins. Items like single-use plastic bags and broken glass screw up sorting machines at recycling centers, costing time and adding to repair expenses.

Many non-recyclable items, such as prescription drug containers and mini-plastic bottles, are so small that they jam up sorting machines. Other materials, such as Styrofoam of any type, simply can’t be recycled with current technology. Those materials should be put in with regular garbage, which can be burned to generate electricity.

State and local officials and garbage hauling companies are continuing their attempts to educate consumers about what should and should not be put in those blue recycling bins. You can double check on what should or should not be recycled on the state’s RecycleCT.com website.

Plastic bags

Single-use plastic shopping bags shouldn’t be put in with other recycling. They can be returned to many grocery and retail stores that now have special separate containers for plastic bag recycling, or thrown away with regular garbage to be burned.

Broken glass, window glass, mirrors, light bulbs

Ceramics, appliances

Items like ceramic dishes, toasters, and irons must not be put in recycling bins.

Non-food aerosol cans

Aerosol spray cans used for non-food products such as bug spray and spray paint should not be recycled. Food aerosol cans such as those for vegetable spray or whipped cream that have any food left in them are also banned from recycling bins.

Prescription drug containers

Knives, syringes, needles

Household waste

Paper towels, tissue, sanitary products and other regular trash cannot be recycled.

Wax paper, wrapping paper, shredded paper

Dog and cat food bags

Greasy cardboard containers

While pizza boxes that are free of any food residue or heavy grease can be recycled, any cardboard pizza or take-out containers contaminated with any grease, oil or food remnants are prohibited.

Styrofoam

Toxic fluid containers

Any bottles or cans that contained antifreeze, pesticides, motor oil, paint, household cleaners or other toxic materials must not be recycled.

Separate plastic container caps

Do not put separate plastic caps from containers for milk, soda or any other liquid in recycling unless they are screwed on to the original container.

Scrap metal

Metal pieces that aren’t part of any container, such as wire coat hangers, should not be put in recycling.

What materials are recyclable?
