Did You Know?

Recycling a single aluminum can saves enough energy to power a TV for 3 hours. In the time it takes you to read this sentence, over 100,000 aluminum cans have been produced worldwide. Most cans are back on store shelves as new cans within 60 days of being recycled.

Did You Know?

Contamination is the biggest challenge in recycling. When non-recyclable items are mixed in (called "wish-cycling"), they can cause entire truckloads to be sent to the landfill. When in doubt, throw it out rather than risk contaminating recyclables.

Frequently Asked Questions

Q What plastics can be recycled curbside?

Most curbside programs accept plastics #1 (PET/PETE) and #2 (HDPE). These include water bottles, soda bottles, milk jugs, and detergent containers. Plastics #3-#7 vary by municipality. Always check with your local recycling program for specifics, and make sure containers are rinsed and empty before recycling.

Q Can pizza boxes be recycled?

Clean pizza boxes can be recycled with cardboard., if the box is heavily soiled with grease and food residue, the greasy portions should be torn off and composted or discarded. The clean top lid can still be recycled. Many composting programs also accept greasy pizza boxes.

Q How do I recycle electronics and batteries?

Electronics (e-waste) and batteries should never go in your regular recycling bin. Most communities have e-waste drop-off locations, and retailers like Best Buy and Staples offer free electronics recycling. For batteries, look for battery recycling drop-off bins at hardware stores or contact your local waste management for collection events.

Q What do the recycling numbers 1-7 mean?

The numbers inside the recycling triangle identify the type of plastic resin: #1 PET (water bottles), #2 HDPE (milk jugs), #3 PVC (pipes), #4 LDPE (plastic bags), #5 PP (yogurt containers), #6 PS/Styrofoam (disposable cups), and #7 Other (mixed plastics). Numbers 1 and 2 are most widely recycled, while 3-7 acceptance varies by location.

Q Should I rinse containers before recycling?

Yes, containers should be rinsed to remove food residue before recycling. They do not be spotless, but a quick rinse prevents contamination that can cause entire batches of recyclables to be sent to the landfill. Heavily soiled items that cannot be cleaned should be placed in the trash.
