Can You Recycle Sunscreen Cans? A Comprehensive Guide to Responsible Disposal
The short answer is: it depends. While sunscreen cans, particularly aerosol types, can be recycled, the process is often more complex than recycling other aluminum or steel containers and requires specific preparation to ensure proper processing.
Understanding Sunscreen Can Composition and Recycling Challenges
Sunscreen cans are made from either aluminum or steel, both recyclable materials. However, several factors hinder their successful entry into the recycling stream. These include residual product, pressurized contents in aerosol cans, and the potential for contamination.
Aerosol vs. Non-Aerosol Sunscreen Cans
It’s crucial to differentiate between aerosol sunscreen cans and non-aerosol (pump or tube) sunscreen containers. Aerosol cans pose a greater risk due to the presence of propellants, which can be flammable and explosive if not handled correctly. Non-aerosol containers, while technically recyclable if made of recyclable materials, often face challenges due to residue.
Residue Concerns
The most significant barrier to recycling sunscreen cans, regardless of type, is the residual sunscreen product. Even seemingly empty cans typically contain some leftover sunscreen. This residue can contaminate batches of recycled materials, rendering them unusable and defeating the purpose of recycling.
How to Properly Prepare Sunscreen Cans for Recycling
Successfully recycling sunscreen cans requires following specific guidelines, which vary depending on local recycling regulations.
Emptying the Can (As Much As Possible)
The first step is to completely empty the can of sunscreen. This is more challenging with aerosol cans, but holding the nozzle down until only propellant is released is essential. For non-aerosol containers, scrape out as much remaining product as possible.
Checking Local Recycling Guidelines
Before placing any sunscreen can in the recycling bin, consult your local recycling program’s guidelines. Many municipalities have specific instructions regarding aerosol cans and residual product. Some may accept them curbside, while others require special drop-off locations or prohibit them altogether.
Venting Aerosol Cans (If Permitted)
Some recycling programs allow residents to vent aerosol cans before recycling. This involves puncturing the can to release any remaining pressure. However, this is a dangerous procedure and should ONLY be done if explicitly instructed by your local recycling program and only in a well-ventilated area, away from heat, sparks, and open flames. Improper venting can lead to explosions and serious injury. If unsure, do not vent the can!
Removing Plastic Caps and Components
Remove any plastic caps, nozzles, or other non-metallic components from the sunscreen can. These are often made from different types of plastic and can contaminate the recycling stream if mixed with metals.
Alternative Disposal Options
If recycling sunscreen cans isn’t feasible due to local restrictions or concerns about proper preparation, consider alternative disposal options.
Hazardous Waste Disposal
Some municipalities offer hazardous waste disposal programs for aerosol cans and other products containing potentially harmful substances. Contact your local waste management authority to inquire about these programs.
TerraCycle Programs
TerraCycle offers specialized recycling programs for hard-to-recycle items, including some types of sunscreen packaging. Check their website to see if they have a program that accepts your specific type of sunscreen container.
Frequently Asked Questions (FAQs)
FAQ 1: What happens if I throw a full aerosol sunscreen can in the trash?
Throwing a full aerosol sunscreen can in the trash poses significant risks. The can could explode due to heat or pressure buildup during transportation or at the landfill. This explosion can injure workers, damage equipment, and potentially start fires. Additionally, the contents of the sunscreen can leach into the environment.
FAQ 2: Can I recycle aerosol sunscreen cans with a little bit of product left in them?
Ideally, sunscreen cans should be completely empty before recycling. However, some local recycling programs may accept cans with a small amount of residual product. Always check with your local authorities. If they don’t accept it with residue, it should go in the trash.
FAQ 3: How do I know if my sunscreen can is aluminum or steel?
A simple test is to use a magnet. Aluminum is non-magnetic, while steel is magnetic. If a magnet sticks to the can, it’s steel; if it doesn’t, it’s aluminum.
FAQ 4: What are the environmental benefits of recycling sunscreen cans?
Recycling sunscreen cans conserves natural resources, reduces energy consumption, and minimizes landfill waste. Recycling aluminum, for instance, requires 95% less energy than producing new aluminum.
FAQ 5: Are pump-action sunscreen bottles easier to recycle than aerosol cans?
Pump-action bottles can be easier to recycle if they are made of recyclable plastic (check the recycling symbol) and are thoroughly cleaned and emptied. However, the pump mechanism itself is often made of mixed materials and may not be recyclable. Remove it before recycling the bottle.
FAQ 6: Can I recycle sunscreen tubes?
Sunscreen tubes are notoriously difficult to recycle. They are often made of mixed materials (plastic and aluminum layers) that are hard to separate. Check the tube for a recycling symbol and consult your local recycling guidelines. If they are not accepted, they should go in the trash. TerraCycle may offer a specialized solution.
FAQ 7: What is the best way to clean out a sunscreen bottle or tube?
Scrape out as much product as possible with a spatula or similar tool. Then, rinse the container with warm, soapy water. However, avoid using excessive amounts of water, especially if you live in a drought-prone area.
FAQ 8: What are some eco-friendly alternatives to traditional sunscreen?
Consider using mineral-based sunscreens with zinc oxide or titanium dioxide as active ingredients. These are generally considered safer for the environment and marine life. Also, look for sunscreens with minimal packaging or that come in reusable containers.
FAQ 9: Can I recycle the plastic cap from my sunscreen can?
It depends on the type of plastic the cap is made from and your local recycling guidelines. Check the cap for a recycling symbol and consult your local recycling program’s instructions. If accepted, make sure to clean the cap before placing it in the recycling bin.
FAQ 10: Is it safe to puncture an aerosol sunscreen can to empty it?
Puncturing an aerosol can is generally not recommended and should ONLY be done if explicitly instructed by your local recycling program and only in a well-ventilated area, away from heat, sparks, and open flames. There is a risk of explosion or fire if done improperly. Most recycling programs advise against it.
FAQ 11: What should I do if my local recycling program doesn’t accept aerosol cans?
If your local program doesn’t accept aerosol cans, explore alternative disposal options like hazardous waste collection events or mail-in recycling programs like TerraCycle.
FAQ 12: Where can I find more information about recycling in my area?
Contact your local waste management authority or visit their website. Many municipalities provide detailed information about recycling guidelines, accepted materials, and drop-off locations. Also, look for resources and guides from organizations like the EPA and Earth911.
