Wishcycling Warning:
"Wishcycling" — putting non-recyclable items in the bin hoping they'll be recycled — actually harms the recycling stream. A single contaminated load can send thousands of pounds of good recyclables to landfill. When in doubt, leave it out.

Use the Recycling Planner tab to set CO₂ savings goals, track monthly recycling history, and use What-If sliders to simulate behavior changes.
Formula & Methodology
CO₂ saved = weight × emission_factor_delta
Difference in CO₂e between virgin production and recycled production per ton. Source: EPA WARM v16.
Energy saved = weight × (virgin_energy − recycled_energy)
Aluminum recycling saves 95% of the energy vs smelting virgin ore — the largest energy savings of any common material.
The difference in CO₂e between producing material from virgin sources vs. recycled feedstock. Aluminum's delta is 9.15 t/ton — the highest of common materials.
Circular Economy
An economic model designed to eliminate waste by keeping materials in use as long as possible through reuse, repair, and recycling.
Closed-loop Recycling
Recycling a material back into the same product (e.g., aluminum can to aluminum can). Aluminum does this nearly indefinitely without quality loss.
Down-cycling
Recycling a material into a lower-quality product (e.g., plastic bottles into fleece). Limits the number of future recycling cycles.
Contamination Rate
The percentage of recyclables rejected due to food residue, incorrect sorting, or mixing of materials. Contamination can invalidate entire truckloads.
Embodied Carbon
CO₂ emitted during extraction, processing, and manufacturing of a material from raw resources — avoided when recycled material is used instead.
EPA WARM Model
Waste Reduction Model v16 — the authoritative US source for recycling emission factors used in this calculator, covering 61 material types.
Result: ~0.6 t CO₂e/yr saved · $115/yr market value · 78 trees/yr equivalent
Example
Aluminum Champion
100 aluminum cans recycled per month (~2 lbs). Small effort, outsized impact due to aluminum's 9.15 t CO₂/ton factor.
Result: 0.028 t CO₂/yr · 28 kWh saved · $21/yr at $0.87/lb
Example
E-waste Recycling
Just 5 lbs/year of old electronics (one laptop) sent to e-waste collection instead of landfill.
Result: 0.050 t CO₂e — equivalent to recycling 50+ lbs of aluminum or 140 lbs of paper!
The Real Impact of Recycling: Energy, Carbon, and Resources Saved
Why Recycling Matters for Climate
Recycling reduces greenhouse gas emissions in two primary ways: it avoids the energy-intensive extraction and processing of virgin raw materials, and it prevents organic waste from decomposing in landfills where it generates methane. The EPA estimates that recycling and composting in the US prevents about 186 million metric tonnes of CO₂e annually — equivalent to taking 39 million cars off the road.
Aluminum: The Recycling Champion
Aluminum recycling is the most impactful single-material recycling action. Smelting aluminum from bauxite ore requires about 14 kWh per kg; recycling aluminum requires only 0.7 kWh — a 95% energy reduction. Recycling one aluminum can saves enough energy to run a TV for 3 hours. Aluminum can be recycled infinitely without quality loss, making it the rare truly circular material. The US recycling rate for aluminum cans is only about 45%.
Copper, E-waste, and High-Value Streams
Copper recycling saves up to 90% of the energy of primary copper production and commands $3.50/lb at the scrap yard — making it both environmentally and financially rewarding. E-waste (phones, computers, batteries) contains rare earth metals requiring extremely energy-intensive mining. Recovering these avoids 20 t CO₂e per ton recycled. US manufacturer take-back programs and retailer drop-offs make e-waste recycling widely accessible.
Plastic Recycling: More Complicated Than It Seems
Only resins #1 (PET) and #2 (HDPE) are widely recycled in most US curbside programs. Resins #3–7 are rarely recyclable. Most plastic is "down-cycled" rather than closed-loop recycled. The effective US plastic recycling rate is under 10%. Reduction and reuse are far more impactful for plastic than recycling.
The Contamination Challenge
Recycling contamination — putting non-recyclables or dirty materials in the bin — is a major challenge that reduces material value and increases processing costs. A single contaminated load can invalidate an entire truckload of recyclables. Key rules: rinse food residue from containers, never put plastic bags in curbside bins, and when in doubt, look it up or leave it out.
More Questions Answered
Does recycling actually make a difference? +
Yes, significantly. The EPA estimates that recycling and composting prevented 186 million metric tonnes of CO₂e in the US in 2018 — equivalent to 39 million cars off the road. Aluminum recycling alone saves 95% of the energy of primary production. The key is recycling correctly (clean, dry, sorted) to avoid contamination.
Which materials are most important to recycle? +
In order of CO₂ savings: e-waste (20 t/ton), aluminum (9.15 t/ton), copper (3.5 t/ton), textiles (2.0 t/ton), plastic (1.53 t/ton), steel (1.46 t/ton), paper (0.84 t/ton), cardboard (0.39 t/ton), glass (0.31 t/ton). By market value: copper ($3.50/lb), aluminum ($0.87/lb), plastic HDPE ($0.40/lb).
Why is glass recycling complicated? +
Glass is 100% recyclable and can be recycled infinitely, but broken glass contaminates paper and cardboard streams in single-stream collection. Many programs now landfill glass because processing cost exceeds recovered material value. Drop-off glass recycling programs are more effective than curbside. Reusing glass jars is more impactful than recycling in most cases.
What happens to my recycling after collection? +
Recyclables go to a Materials Recovery Facility (MRF) where they are sorted by material type using screens, magnets, optical sensors, and manual sorting. Sorted materials are baled and sold to manufacturers who use them as raw material inputs. About 30% of what Americans put in recycling bins is actually recycled due to contamination and limited markets.
Is it worth recycling if I'm not sure it's recyclable? +
No — "wish-cycling" causes contamination that can ruin entire truckloads. When in doubt, look it up or throw it out. Most US cities have recycling guidelines on their websites. The most reliable materials are: aluminum cans, steel cans, cardboard, paper, plastic bottles (#1 and #2), and glass (where accepted).
What is e-waste recycling? +
Electronic waste (computers, phones, TVs, batteries) contains valuable materials (gold, silver, copper, rare earth elements) and hazardous materials (lead, mercury, cadmium). It should never go in regular trash or recycling. US manufacturers and retailers offer take-back programs; Best Buy, Staples, and many municipalities have free e-waste drop-off. The EPA estimates 1 million recycled cell phones recovers 35,274 lbs of copper, 772 lbs of silver, and 75 lbs of gold.
How does composting compare to recycling? +
Composting is the preferred end-of-life for food waste and yard trimmings, diverting organic matter from landfills where it would generate methane. For paper and cardboard, recycling is preferable to composting as it recovers the fiber value. The two are complementary strategies, not alternatives — the most effective waste reduction strategy uses both.
