Curbside recycling statistics show both the scale of the system and the limits of current measurement. In a 2024 U.S. survey, 52% of responding states and territories reported collecting data on community curbside programs, while an Oregon study measured a 15.48% inbound contamination rate in 2023. Nationally, paper and paperboard remained the largest tracked material category in the latest supplied national baseline, with a 68.2% recycling rate in 2018.

U.S. curbside access and data coverage
The Recycling Needs Survey and Assessment Report to Congress describes how unevenly curbside recycling is measured. Its 2024 report covered 59 responding U.S. states and territories, but not every respondent collected the same indicators.
Thirty-one respondents, or 52%, reported collecting data on the number of community curbside recycling programs. Drop-off programs were better covered: 37 respondents, or 63%, collected data on their number. Only 27 respondents, or 46%, reported collecting annual tonnage data for residential materials collected through curbside programs.
Program rules were more commonly tracked than outcomes. Thirty-eight respondents, or 64%, collected data on materials accepted by each recycling program. By comparison, 21 respondents, or 36%, collected data on the number of citizens with recycling-service access comparable to waste-disposal access.
Two metrics especially relevant to curbside performance were reported by only 9 respondents each. That represents 15% of respondents collecting inbound contamination rates and 15% collecting capture rates for community recycling programs. These figures are measures of data coverage, not national averages for contamination or capture.
State-level recycling rates were also incomplete. Thirty respondents, or 51%, measured a state- or territory-level recycling rate. The 29 reported rates ranged from 9% to 56%, with a mean of 32%. Among 52 respondents that provided an estimate, mean community access to curbside recycling was 44%, with estimates ranging from 0% to 100%.
The coverage differences matter when comparing communities. A program may have a list of accepted materials without a corresponding tonnage series, contamination estimate, or capture-rate estimate. Likewise, an access estimate can describe a state or territory broadly while masking differences among individual communities. The 2024 report’s respondent counts therefore describe what agencies reported measuring during that reporting period; they do not establish that every U.S. curbside program had the same level of service or data quality.
Infrastructure needs and recovery potential
The U.S. Recycling Infrastructure Assessment and State Data Collection Reports identified packaging and organic materials commonly targeted by recycling systems as approximately 82% of the municipal solid-waste stream. That estimate describes the potential material base for system improvements; it does not mean all of that material is currently accepted or recovered through curbside collection.
For a 2030 projection, the assessment estimated that modernizing U.S. curbside collection, drop-off, and processing infrastructure would require $36.5 billion to $43.4 billion. The rounded low-to-high estimate for curbside collection alone was $19.9 billion to $21.5 billion. The modeled low-end curbside investment was $18,905,264,244, excluding education and outreach, while the modeled high-end investment was $20,444,264,244, also excluding education and outreach.
The modeled investment scenario estimated an additional 82 million to 89 million tons of packaging and organic waste could potentially be recovered. That potential additional recovery represented a 91% increase over the 94 million tons the assessment estimated were recycled or composted in 2018. Under the same scenario, the modeled national recycling rate rose from 32% to 61%. These are projections, not observed 2030 results.
National recycling benchmarks by material
The Advancing Sustainable Materials Management: Facts and Figures 2018 provides a national baseline for materials often discussed alongside curbside collection. U.S. municipal solid-waste generation was approximately 292 million short tons in 2018. About 69 million short tons were recycled, and about 94 million short tons were managed through recycling and composting combined, producing a combined rate of 32.1%.
Paper and paperboard generated 67.4 million short tons, or 23.1% of total municipal solid-waste generation. Approximately 46.0 million short tons were recycled, equivalent to a 68.2% recycling rate. Within that category, corrugated boxes had a 96.5% recycling rate, while newspapers or mechanical papers had a 64.8% rate. All paper and paperboard containers and packaging had an 80.9% recycling rate.
The following 2018 rates show how outcomes differed among commonly tracked packaging materials:
| Material category | 2018 recycling rate |
|---|---|
| Corrugated boxes | 96.5% |
| Paper and paperboard containers and packaging | 80.9% |
| Other steel packaging | 81.0% |
| Steel cans | 70.9% |
| Newspapers or mechanical papers | 64.8% |
| Total glass packaging | 31.3% |
| Total plastics packaging | 13.6% |
These national figures are from 2018 and are not curbside-only rates. They are useful benchmarks for understanding the material mix that recycling systems may handle, but they should not be presented as current local program performance.
Oregon contamination rates
The 2023 Oregon Inbound Commingled Recycling Composition Study provides a detailed example of curbside-related stream measurement. Oregon’s 2023 statewide inbound commingled-cart contamination rate was 15.48%, based on 379 samples and 291,922 collected tons.
Rates varied across the reported areas. Metro Oregon recorded 17.05% contamination with 178,272 tons collected. Marion County recorded 14.69% with 19,459 tons, while Lane County recorded 12.39% with 30,567 tons. Willamette Valley and similar Oregon counties recorded 15.64% with 26,136 tons.
The reported rates were lower in several other areas. Deschutes County recorded 12.12% contamination with 13,126 tons collected. Coastal counties recorded 13.43% with 9,110 tons, Southwest Oregon counties recorded 8.91% with 9,010 tons, and Eastern Oregon counties recorded 6.91% with 6,242 tons.
Oregon commingled stream composition
The Oregon study classified 84.52% of the 2023 commingled stream as acceptable in the cart and 15.48% as not acceptable. Paper dominated the measured stream at 79.79%, including 76.50% cart-acceptable paper. Cardboard and brown bags alone accounted for 50.88% of the stream.
Newspapers accounted for 2.55%, while magazines accounted for 3.67%. Plastic made up 8.74%, including 4.55% cart-acceptable plastic. Not-cart-acceptable rigid plastic represented 3.02%, and film plastic represented 1.17%.
Metal made up 4.07% of the stream, including 3.47% cart-acceptable metal. Glass represented 2.03%, including 0.37% deposit beverage glass. Food, wood, and yard debris represented 1.35%, while bagged garbage represented 2.38%.
The material shares help explain why a contamination rate is not the same as a single-item error rate. The study measured a broad commingled stream containing acceptable material alongside multiple types of material that were not acceptable in the cart.
How Oregon’s stream changed
Oregon’s total commingled collection was 291,922 tons in 2023, compared with 288,599 tons in 2009. Within that total, acceptable material fell from 261,461 tons in 2009 to 246,744 tons in 2023. Not-acceptable material rose from 27,135 tons to 45,178 tons over the same comparison.
Several material categories also changed in collected tonnage:
| Category | 2009 | 2023 |
|---|---|---|
| Cardboard and brown bags | 73,112 tons | 148,535 tons |
| Total plastic | 21,461 tons | 25,504 tons |
| Total glass | 2,926 tons | 5,935 tons |
| Bagged garbage | 3,532 tons | 6,945 tons |
The study reported that Oregon’s population grew 12.6% from 2009 to 2023, while total commingled collection increased by about 1%. This comparison covers different years and should be read as a description of changes in the measured totals, not as a per-person calculation.
Newspapers show the strongest composition shift in the supplied Oregon measurements. They were nearly 44% of Oregon household commingled-bin material in 2004, about 23% of the total commingled stream in 2009, and 2.55% in 2023. The figures mark changes in the stream’s composition across 2004, 2009, and 2023; they do not establish the cause of that change.
