In the United States, about 32% of all municipal solid waste gets recycled or composted. That means roughly two-thirds of everything Americans toss into any bin, recycling or otherwise, ends up in a landfill or incinerator. And for specific materials like plastic, the picture is far worse. The real answer depends heavily on what you’re recycling, where you live, and whether your local facility can actually process what you put in the bin.
The Overall Numbers
Americans generated 292.4 million tons of municipal solid waste in 2018, the most recent year with comprehensive EPA data. Of that, about 69 million tons were recycled and 25 million tons were composted, bringing the combined recycling and composting rate to 32.1%. That sounds modest, and it is. But buried inside that average are wildly different success rates depending on the material.
Plastic: The Worst Performer
Plastic is the material most people picture when they wonder about recycling, and it’s also the one with the most dismal numbers. Of the 35.7 million tons of plastic waste generated in the U.S. in 2018, only about 3 million tons were actually recycled. That’s an 8.7% recycling rate. Another 5.6 million tons were burned for energy. The remaining 27 million tons went straight to landfills, making plastic 18.5% of all landfilled waste.
The low rate isn’t just about consumer laziness. Most plastic products are technically recyclable in theory but not in practice. There are seven major categories of plastic resin, and most curbside programs only reliably process two of them: the type used in water bottles and the type used in milk jugs. Thin films, clamshell containers, plastic bags, and mixed-material packaging are either rejected at sorting facilities or contaminate other recyclable material when they’re tossed in the wrong bin.
Paper, Metal, and Glass Do Much Better
Not all recycling is a lost cause. Paper and cardboard have historically achieved recycling rates above 60% in the U.S., and aluminum cans are recycled at rates around 35 to 50% depending on the year and source. These materials hold their value through multiple recycling cycles, and the infrastructure to process them is well established. Glass can be recycled indefinitely without losing quality, though heavy weight and transportation costs sometimes make it less economically attractive than producing new glass.
The key difference is demand. Manufacturers want recycled aluminum because melting down old cans uses about 95% less energy than smelting new aluminum from ore. Recycled paper fiber is cheaper and easier to source than virgin pulp for many products. These economics keep collection and processing viable in ways that plastic simply can’t match.
Why Recycled Plastic Can’t Compete on Price
One of the biggest barriers to plastic recycling is straightforward economics. In 2023, scrap polyethylene plastic sold for about €330 per ton in Europe, while virgin polyethylene cost around €1,444 per ton. At first glance, that price gap should favor recycled material. But the cost of collecting, sorting, cleaning, and reprocessing plastic waste often erases the savings, especially when oil prices drop and make new plastic even cheaper to produce.
Quality is the other problem. Recycled plastic degrades with each processing cycle. The polymer chains shorten, making the material weaker and less versatile. This means recycled plastic often can’t be used for food packaging, medical supplies, or other applications with strict safety standards. It gets “downcycled” into lower-value products like park benches, carpet fiber, or fleece jackets, and those products typically aren’t recycled again at end of life.
What Happens at the Sorting Facility
When your curbside recycling truck hauls away your bin, the contents go to a Material Recovery Facility, or MRF. These facilities use a combination of spinning discs, magnets, air jets, optical scanners, and human sorters to separate paper, plastic, glass, and metal into commodity streams that can be sold to manufacturers.
The process isn’t perfect. MRFs across the U.S. report residue rates (the percentage of incoming material that can’t be recycled and gets landfilled) averaging under 20%, though individual facilities range from as low as 1% to as high as 39%. The biggest culprits are food-contaminated containers, plastic bags that jam sorting machinery, and items that never belonged in the recycling bin in the first place: garden hoses, clothing, electronics, diapers. When contamination gets bad enough, entire bales of otherwise recyclable material get rejected and sent to landfill.
Where Exported Recycling Ends Up
For years, the U.S. dealt with much of its plastic waste by shipping it overseas, primarily to China. In 2018, China enacted its “National Sword” policy and effectively banned imports of most plastic scrap, citing contamination. The waste stream redirected to Southeast Asia, with Malaysia becoming the largest importer of U.S. plastic waste, followed by Vietnam, Indonesia, and Thailand.
These countries often lack the infrastructure to process the volume they receive. Investigations by journalists and environmental groups have documented imported plastic waste being dumped in open landfills, burned in open pits, or left in illegal stockpiles. The actual recycling rate for exported plastic is difficult to verify, but the shift away from China, which at least had large-scale processing capacity, almost certainly lowered it. Several Southeast Asian nations have since imposed their own import restrictions, further shrinking the export market.
What Actually Improves Recycling Rates
The places with the highest recycling rates share a few common features. Deposit-return programs, where you pay a small fee on a bottle or can and get it back when you return the container, consistently achieve return rates of 80% or higher for the materials they cover. Germany’s deposit system for plastic bottles recovers over 90% of them.
Single-stream recycling, where all recyclables go in one bin, made recycling more convenient and boosted participation rates when it was introduced. But it also increased contamination because people started tossing in items they hoped were recyclable. Some cities have moved back toward dual-stream systems, separating paper from containers, to reduce contamination and improve the quality of sorted material.
Extended producer responsibility laws, which require manufacturers to fund the recycling of their own packaging, have driven significant improvements in Europe and parts of Canada. When companies bear the cost of end-of-life processing, they have a financial incentive to design packaging that’s easier to recycle, use fewer material types, and avoid hard-to-process combinations like paper laminated with plastic film.
How to Make Your Recycling Count
The single most effective thing you can do is learn what your specific local program accepts and stick to it. Recycling rules vary dramatically between cities, and putting the wrong item in the bin does more harm than leaving a recyclable item out. Plastic bags, for instance, are recyclable at many grocery stores but will shut down the sorting line at most MRFs if they end up in curbside recycling.
Empty and rinse containers before recycling them. A peanut butter jar with residue inside can contaminate an entire bale of plastic. Keep paper and cardboard dry. Flatten boxes to save space in collection trucks. And when in doubt, throw it out. “Wish-cycling,” the habit of tossing questionable items in the recycling bin and hoping for the best, is one of the leading causes of contamination at sorting facilities.
The broader reality is that recycling alone was never designed to solve the waste problem. Even with perfect sorting and zero contamination, the infrastructure and economics only support recycling about a third of what we generate. Reducing consumption and reusing materials before they ever reach the recycling bin remain the most effective ways to keep waste out of landfills.
