8 Things You're Probably Putting in the Trash That Can Actually Be Recycled
Your bin isn't as smart as you think, but neither is the trash can, and these eight items deserve a second look before they end up in a landfill.
Most of us think we’ve got recycling figured out. Bottles go in the bin, cardboard gets flattened, and everything else is trash, right? Not quite. Americans send over 146 million tons of recyclable material to landfills every year, and a lot of it isn’t because people don’t care. It’s because nobody told them the item in their hand had options. 🗑️
I’m not talking about obscure stuff either. These are things sitting in your kitchen, bathroom, and junk drawer right now. Here’s what you’ve probably been trashing that deserves a second chance. ♻️
Pizza boxes (yes, even the greasy ones)
The pizza box myth is one of the most persistent pieces of bad recycling advice out there, and it’s not entirely wrong, just incomplete. Grease and food residue are genuinely bad for paper fiber recycling, but that doesn’t mean the whole box is doomed. 🍕
The actual rule is simpler than people assume. If the lid is clean, tear it off and recycle it separately from the greasy base, which goes in the trash or the compost bin. A soaked-through box, top to bottom, does need to go in the trash, since grease contaminates the paper pulping process. GreenInch’s own breakdown of common recycling mistakes points out that grease and food residue are the enemy of paper fiber recycling, but a little moderation goes a long way toward saving what’s salvageable:
Tear off and recycle any clean, ungreased sections of the box
Trash the greasy bottom section rather than tossing the entire box
Compost the greasy parts if your municipality accepts food-soiled cardboard
Never crumple a fully soaked box into your bin hoping it’ll sort itself out. It won’t, and it can contaminate the whole batch
Coffee pods and K-Cups
Single-serve coffee feels like a modern convenience, and it is, but it also generates an absurd amount of small, mixed-material waste. Each pod is really three products glued together: plastic, aluminum, and coffee grounds, all of which need to be pulled apart before any of it can go anywhere useful. ☕
The scale is bigger than most people register. Nespresso has collected over 120,000 tons of used capsules through its own take-back program, recovering both the aluminum shell and the leftover grounds for composting. Keurig-style K-Cups require a bit more elbow grease on your end, since they’re not accepted whole by most curbside programs.
Peel back the foil top and recycle it separately, most curbside programs take clean foil
Compost the coffee grounds directly, they’re great for gardens
Recycle the plastic cup only if your local program explicitly accepts small rigid plastics, check first
Look into brand-specific mail-back programs if your area doesn’t handle any of this curbside
Empty shampoo, lotion, and toiletry bottles
The bathroom is where recycling habits go to die. People diligently sort kitchen containers, then toss a nearly identical shampoo bottle straight in the trash without a second thought. It’s the same plastic, just a different room. 🧴
Most shampoo, conditioner, and body wash bottles are made from #1 (PET) or #2 (HDPE) plastic, the two most widely accepted plastic types in curbside programs nationwide. The catch is usually contamination, a bottle with an inch of leftover product in the bottom, or a pump top still attached, can get an entire load rejected at the sorting facility.
Rinse out any residue before tossing bottles in the bin. A quick shake with water works fine
Remove pumps, spray triggers, and non-plastic caps, since these often aren’t recyclable in the same stream
Check the tiny number inside the recycling triangle on the bottom. Stick to #1 and #2 unless your program says otherwise
Keep a small bathroom recycling bin next to the trash can, so the habit becomes automatic instead of an afterthought
Wine corks
Nobody thinks twice about a used wine cork. It goes straight in the trash after the bottle’s empty, mostly because there’s no obvious “cork bin” at the curb. But both natural and synthetic corks have real second lives. 🍷
ReCORK has recycled over 110 million natural corks into products like footwear and yoga blocks, turning what would be landfill filler into something people actually use. Synthetic corks, the ones made from plastic rather than actual cork bark, can usually go straight into your regular plastic recycling instead of a specialty program.
Save natural corks in a jar and drop them at a grocery store or wine shop with a ReCORK collection bin
Toss synthetic (plastic) corks into your normal curbside plastic recycling
If there’s no drop-off point near you, mail-in options exist through ReCORK’s own program
Skip the landfill route entirely if you go through more than a bottle or two a month. It adds up fast
Batteries of every kind
This is the one where “just throw it away” is actually dangerous, not just wasteful. Batteries, disposable and rechargeable alike, contain metals that shouldn’t be anywhere near groundwater. ⚡
Recycled batteries yield back lithium, zinc, and manganese that manufacturers can use again in new batteries, cutting down on the mining required to extract virgin materials. It’s also worth knowing that in some states, tossing rechargeable batteries in the regular trash is flat-out illegal, not just discouraged.
Drop off both single-use and rechargeable batteries at hardware stores, Best Buy, and Home Depot, most run free take-back bins near the entrance
Never throw lithium-ion batteries in curbside recycling. They can spark fires in collection trucks and sorting facilities
Tape over the terminals of loose batteries before storing them for drop-off, to prevent accidental short-circuits
Check whether your city runs periodic hazardous waste collection days if you don’t have a nearby retail drop-off
Printer and ink cartridges
An empty ink cartridge looks like garbage the moment the printer flashes its low-ink warning. In reality, it’s a small, dense object built from plastic and residual ink chemicals that don’t belong loose in a landfill. 🖨️
Plenty of office supply retailers will take these off your hands for free, and some sweeten the deal further with a discount on your next cartridge purchase, which is about as close to a win-win as recycling gets.
Return empty cartridges to office supply stores like Staples or Office Depot, both run ongoing take-back programs
Ask about loyalty discounts. Several retailers reward you for each cartridge returned
Check if your cartridge brand offers a prepaid mail-back envelope, many do
Buy remanufactured cartridges when you can. It closes the loop instead of just slowing it down
Old eyeglasses
Old prescription glasses tend to pile up in a drawer for years before anyone decides what to do with them, and “throw them away” usually wins by default once the drawer gets too full. That’s a shame, because glasses are one of the easiest donation-and-recycle combos out there. 👓
Individual components, lenses, frames, and nose pads, can be separated and repurposed, and there’s an established donation network built specifically for this.
Donate wearable glasses to organizations like OneSight, which redistributes them to people who need vision correction and can’t afford it
Drop off old pairs at LensCrafters or Walmart Vision Centers, both accept donations at the counter
Recycle broken or unusable frames through local eyewear recyclers if donation isn’t an option
Don’t let a broken pair make the decision for you. Even non-wearable frames often have recyclable plastic or metal components
Plastic bags and film
This is the item most people get wrong in the opposite direction. Plastic bags absolutely should not go in your curbside bin, but that doesn’t mean the trash is the only other option. 🛍️
Plastic film jams sorting machinery at recycling centers, which is exactly why curbside programs reject it and why so many people assume it’s simply not recyclable. It is, just through a separate channel. Major grocery chains run dedicated drop-off bins, usually near the entrance, that funnel collected film into composite lumber and other products instead of a landfill.
Bundle bags together before dropping them off, loose bags are harder to process
Look for collection bins at grocery store entrances. Most major chains participate
This applies to more than shopping bags: bread bags, produce bags, and shipping envelope liners usually qualify too
Never put plastic film in your curbside bin, even if it feels like the “recyclable” thing to do. It causes real damage to sorting equipment
Once you’ve got these eight sorted out, the bigger habit worth building is just double-checking before something hits the trash. GreenInch’s guide to wishcycling covers the flip side of this problem, items people wrongly assume are recyclable, and it’s worth a read if you want the full picture on both ends.
