submitted 2026年10月22日 by @joe 79
OverviewDid Commingled Curbside Collection Kill Recycling Quality? evaluates how the transition from multi-stream to commingled single-stream collection affected recycling quality across North America. It draws on municipal composition studies and recovery facility audits to argue that single-stream collection drove contamination and residue rates to unsustainable levels. Ultimately, it shows that initial gains in collected…

Themes across the family
A broad read of every map in this family: the themes that run through them and how each map treats them. Structured scans give a more targeted side-by-side.
Sorting Residue and Net Yield Losses
2 / 2 個のマップBoth maps reveal that gross collected tonnage does not translate directly into recycled products, as processing losses and sorting rejections significantly depress final recycling yields.
M1Did Commingled Curbside Collection Kill Recycling Quality?
Emphasizes that single-stream collection inflates contamination and residue rates, frequently causing net drops in tonnage actually recycled.
M2Why Cheap Virgin Feedstocks and Complex Packaging Undermine Recycling Yields
Focuses on mechanical sorting limitations and post-collection yield losses that prevent collected PET and packaging from reaching secondary resin markets.
Contamination and Packaging Incompatibility
2 / 2 個のマップThe maps identify physical and chemical contamination—originating either from mixed curbside carts or multi-material packaging designs—as a major barrier to meeting buyer quality standards.
M1Did Commingled Curbside Collection Kill Recycling Quality?
Highlights how consumer non-recyclables and shattered glass ruin paper batches and prevent recovered commodities from satisfying industrial mill specifications.
M2Why Cheap Virgin Feedstocks and Complex Packaging Undermine Recycling Yields
Details how incompatible packaging components, such as wash-resistant adhesives, full-sleeve labels, and density-matched polymers, contaminate clean flake streams.
Economics of Secondary Material Markets
2 / 2 個のマップThe viability of recycling depends heavily on whether post-consumer processing costs can remain competitive against subsidized or low-cost virgin feedstocks.
M1Did Commingled Curbside Collection Kill Recycling Quality?
Underlines the financial burden on municipal recovery facilities and haulers forced to process high-residue single-stream material and repair equipment.
M2Why Cheap Virgin Feedstocks and Complex Packaging Undermine Recycling Yields
Argues that depressed virgin polymer prices undercut secondary reclaimers, leaving expensive recycled pellets unable to compete and forcing reclaimer closures.
System Design and Policy Interventions
2 / 2 個のマップSystemic recycling outcomes are shaped by policy mechanisms and infrastructure models seeking to balance collection convenience against material purity.
M1Did Commingled Curbside Collection Kill Recycling Quality?
Traces how municipalities transitioned to single-stream collection to maximize public participation, only to later restrict materials like glass or institute cart inspections.
M2Why Cheap Virgin Feedstocks and Complex Packaging Undermine Recycling Yields
Examines virgin plastic taxes, import tariffs, and design-for-recycling guidelines intended to counteract market imbalances and enhance reclaimer yields.
Both maps show that multi-stream or source-separated systems achieve substantially lower residue rates than commingled or mixed-waste processing streams.
M1Did Commingled Curbside Collection Kill Recycling Quality?
C0017MRF stream contamination comparison正確と確認済み
An Oregon DEQ case study of an operating MRF recorded overall contamination rates of 15% for dual-stream versus 30% for single-stream.

M2Why Cheap Virgin Feedstocks and Complex Packaging Undermine Recycling Yields
C0021CalRecycle facility residue rates正確と確認済み
A CalRecycle processor survey found facility residue rates ranging from 5% at certain manual or dual-stream operations to 45% at mixed-waste processing facilities.
情報源リンク付き重要度: 低ChatGPT
Both maps document that gross collection figures significantly overstate actual recycling yields due to heavy processing and screening losses.
M1Did Commingled Curbside Collection Kill Recycling Quality?
C0016Adjusted net recycling rate正確と確認済み
In a Florida county with a 28.2% single-stream contamination rate, an official 58% recycling rate in 2015 dropped to an actual calculated rate of 41.64% after subtracting rejected material.

C0018PET recycling yield loss正確と確認済み
In 2024, North America achieved a 39.2% PET bottle collection rate compared to a 30.2% final recycling rate, creating an approximate 9 percentage point yield loss between collection and actual recycling.
情報源リンク付き重要度: 低Claude
The maps diverge on whether yield loss is fundamentally driven by household cart contamination or by inherent sorting equipment limitations and package design barriers.
M1Did Commingled Curbside Collection Kill Recycling Quality?
C0008Higher single-stream contamination variance正確と確認済み
An ANOVA test confirmed at the 0.999 significance level that single-stream recycling contamination rates are higher and more spread out than dual-stream rates.

M2Why Cheap Virgin Feedstocks and Complex Packaging Undermine Recycling Yields
C0022Sorting equipment process loss正確と確認済み
CalRecycle's survey found a 5% to 10% process loss of target recyclables caused by sorting equipment failures, independent of inbound contamination.
情報源リンク付き重要度: 低ChatGPT
The maps diverge on which stage of the supply chain generates the decisive cost barrier, contrasting curbside collection contamination with post-collection washing and compounding steps.
M1Did Commingled Curbside Collection Kill Recycling Quality?
C0014Inbound contamination tonnage costs正確と確認済み
Waste Management operational data presented to the EPA showed inbound contamination averaged 16% of tons, peaked up to 50% on incoming loads, and cost an average of $140 per ton.

M2Why Cheap Virgin Feedstocks and Complex Packaging Undermine Recycling Yields
C0007Recycling processing cost drivers正確と確認済み
Processing steps—specifically sorting, washing, and compounding—constitute the bulk of recycled resin's price premium over virgin material rather than collection costs.

Did Commingled Curbside Collection Kill Recycling Quality? specifically explores how broken glass acts as a severe abrasive agent that destroys sorting machinery and embeds into paper streams.
M1Did Commingled Curbside Collection Kill Recycling Quality?
C0022Glass damage maintenance costs正確と確認済み
Glass-shard damage at the Shoreline Recycling & Transfer Station cost approximately $500,000 per year exclusively for replacing screen basket valves.
情報源リンク付き重要度: 低Claude
Why Cheap Virgin Feedstocks and Complex Packaging Undermine Recycling Yields specifically develops the role of international trade tariffs and virgin feedstock subsidies in undermining post-consumer plastic economics.
M2Why Cheap Virgin Feedstocks and Complex Packaging Undermine Recycling Yields
C0012Imported rPET tariff exposure正確と確認済み
Recycled PET imports into the U.S. are categorized under the same trade classification codes as virgin PET, exposing imported rPET flakes and pellets to tariff price increases of 8 to 14 cents per pound.
