Recycling Diversion Basics: Mass Math Without Overclaiming Impact
A recycling diversion worksheet is arithmetic on a scenario you control: pounds by material stream for one period, plus a diversion percent that reflects how much of that mass you treat as diverted from disposal. This guide explains that logic in plain language. It is educational only—not an emissions model, commodity-price tool, or guarantee that every sorted pound was accepted.
What a Diversion Worksheet Actually Answers
The useful question is not 'How much carbon did I save?' It is 'If these pounds and this diversion percent are correct, how much mass is treated as diverted from disposal?' A transparent worksheet makes that comparison visible. Real programs reject contaminated loads, residue varies by facility, and remanufacturing yields differ by material. Treat diverted pounds as a planning signal you still need to verify with your hauler or municipality.
Material Streams Plus One Diversion Percent
Most educational recycling worksheets sum paper, cardboard, plastic, metal, glass, and other recyclable pounds for one consistent period, then multiply by diversion percent / 100. Unused streams stay at zero. Keep one period length—do not mix a week of bottles with a month of cardboard unless you intentionally build a combined scenario and label it.
Inputs and What They Do Not Prove
| Input | What it does here | What it does not prove | Common confusion |
|---|---|---|---|
| Material pounds | Builds the recycled mass total you entered | That the facility accepted every pound | Counting wish-cycled items as recycled |
| Diversion percent | Scales total mass treated as diverted | Carbon savings or commodity revenue | Leaving 100% when contamination is common |
| Period total recycled | Sum of the streams you entered | Source reduction or avoided packaging | Mixing reduction goals into recycling pounds |
| Diverted pounds | Total × diversion percent / 100 | ESG compliance or landfill diversion audits | Reporting diverted pounds as emissions avoided |
How the Worksheet Orders the Math
Enter each stream
Use weighed or carefully estimated pounds for paper, cardboard, plastic, metal, glass, and other.
Sum total recycled pounds
Total = sum of all material streams.
Apply diversion percent
Diverted from disposal = total × diversion percent / 100.
Lower the percent when reality is messy
If loads are rejected or residue is high, reduce diversion percent instead of inflating stream pounds.
Run the Recycling Diversion Worksheet
Enter material pounds and a diversion percent you can defend:
Open Recycling Impact CalculatorWorked Scenario Without Claiming Carbon Savings
Suppose paper 20, cardboard 10, plastic 5, metal 3, glass 2, and other 0 pounds with a 90% diversion percent. Total recycled is 40 pounds. Diverted from disposal is 36 pounds. Drop diversion to 70% for contamination and diverted becomes 28 pounds. The worksheet never invents greenhouse-gas factors or scrap values for those pounds.
What This Model Intentionally Omits
- EPA WARM or other emission factors
- Facility-specific residue and contamination rates
- Commodity prices and revenue forecasts
- Guarantees about acceptance by local programs
- Source-reduction avoided pounds (use a plastic reduction worksheet for that)
Diversion Percent Is Not Vanity
A 100% diversion default assumes every entered pound left disposal. Many household and workplace programs do not achieve that. Prefer a conservative percent grounded in program guidance or observed rejections. Honesty beats a round number that looks good in a slide deck.
Bottom Line
Recycling diversion basics are about transparent mass math: sum the streams, apply a diversion percent you can defend, and stop before inventing carbon or revenue claims. Confirm acceptance with local programs, and keep ESG language out of a simple educational worksheet.
