In the United States, about 32% of municipal solid waste is recycled or composted. But that number masks enormous variation by material. Aluminum cans are recycled at roughly 75% globally, while plastic sits below 9%. What actually happens to the items you toss in the blue bin depends heavily on what they’re made of, where you live, and whether anyone is willing to buy the sorted material on the other end.
The Overall US Recycling Rate
The EPA’s most comprehensive data, from 2018, puts the national recycling and composting rate at 32.1%, representing about 94 million tons of material. That rate actually dropped from 34.7% in 2015. The decline coincided with a major disruption in the global recycling market: China’s National Sword policy, implemented in 2018, slashed the country’s imports of waste plastic by 92% and used paper by 56%. The United States had been shipping enormous volumes of recyclable material to China for processing, and when that door closed, much of it had nowhere to go. The amount of plastic sent to US landfills jumped 23.2% after the policy took effect.
How Rates Vary by Material
The 32% national average obscures the fact that some materials cycle back into new products at high rates while others barely get recycled at all.
Paper and cardboard have the strongest recycling performance of any common material in the US waste stream. The overall paper recycling rate was 68.2% in 2018. Corrugated cardboard, the brown boxes from online shopping, led the way at an impressive 96.5%. Newspapers came in at 64.8%. Other paper packaging lagged at 20.8%, partly because coatings and mixed materials make those items harder to reprocess.
Aluminum is the global recycling leader among beverage containers. Aluminum cans reached a 74.8% recycling rate worldwide in 2023, well ahead of PET plastic bottles (47%) and glass bottles (41.9%). Aluminum holds its value through repeated recycling cycles, and melting down old cans uses about 95% less energy than producing new aluminum from raw ore. That economic incentive keeps collection and reprocessing rates high.
Plastic is where the gap between perception and reality is widest. The overall US plastic recycling rate was just 8.7% in 2018, with about 3 million tons actually reprocessed. Certain plastic types do better: PET bottles and jars (the kind used for water and soda) were recycled at 29.1%, and HDPE bottles (milk jugs, detergent containers) hit 29.3%. But the vast majority of plastic products, from clamshell food containers to plastic film to toys, are rarely recycled at all. Many are technically recyclable but lack the collection infrastructure or end markets to make it happen.
Glass falls somewhere in the middle, but its fate depends heavily on where you live. States with bottle deposit laws recycle roughly 65% of glass waste, while states without them recycle about 30%. Glass is infinitely recyclable in theory, but it’s heavy, cheap, and expensive to transport. Many municipalities can’t find buyers for mixed, broken glass and end up using it as a substitute for topsoil at landfills, a practice called “alternative daily cover” that technically counts as diversion from the waste stream but isn’t really recycling in any meaningful sense.
What Happens at the Sorting Facility
When your recycling truck dumps its load at a Material Recovery Facility (MRF), the contents get sorted by material type using a combination of machines and human workers. Single-stream recycling, the now-standard system where all recyclables go in one bin, made recycling more convenient but introduced a serious contamination problem. Mixing paper, plastic, glass, and metal in one container means materials get wet, greasy, or broken before they even arrive at the facility.
A study of four operating MRFs in Florida found that only 31.4% of sorted cardboard samples met the contamination standards required by the paper mills that would buy them. For sorted newspaper, none of the 266 samples tested met mill standards. When sorted material is too contaminated for buyers to accept, it gets landfilled despite having gone through the entire collection and sorting process. This is one of the key points the overall recycling statistics don’t capture: material can be “recycled” by the consumer and counted in collection data, yet never actually become a new product.
Why Some Recyclables End Up in Landfills
Recycling is ultimately a market. Sorted materials are commodities that need buyers, and when prices drop or quality standards tighten, the economics break down. Several factors push recyclable material into landfills even after collection.
- Contamination: Food residue, liquids, and non-recyclable items mixed into recycling bins degrade the quality of otherwise recyclable material. A single greasy pizza box can contaminate a batch of paper.
- Transportation costs: Heavy, low-value materials like glass often cost more to ship to a processing plant than the recycled product is worth. In Puerto Rico, which lacks a government glass recycling program, only 3.8% of glass waste was recycled as of available data.
- Lost export markets: Before China’s import ban, the US relied heavily on overseas processing. The sudden loss of that outlet left domestic facilities overwhelmed, and the country still hasn’t fully built out replacement capacity.
- Material complexity: Multi-layer packaging, black plastic (invisible to optical sorters), and small items that fall through sorting screens all end up as waste regardless of the recycling symbol printed on them.
What Actually Makes a Difference
The single biggest predictor of whether a material gets recycled is its economic value after sorting. Aluminum and corrugated cardboard have strong end markets and consistently high recycling rates. Plastic film and mixed glass do not, and their recycling rates reflect that reality.
Bottle deposit programs, where you pay a small fee when purchasing a beverage and get it back when you return the container, consistently boost recycling rates. The 65% glass recycling rate in deposit states versus 30% in non-deposit states illustrates the effect. These programs create a direct financial incentive and produce cleaner, better-sorted material than curbside collection.
At the individual level, the most impactful thing you can do is keep contamination out of your recycling bin. Rinse containers, keep plastic bags out (they jam sorting equipment), and check your local program’s accepted materials list, because what’s recyclable in one city may not be in another. A smaller bin of clean, genuinely recyclable material is worth far more than a full bin of wishful thinking.
