CRP Data Tracking, Reporting & Program Evaluation 2 — Questions and Answers
Question 1: A recycling coordinator is writing the annual report and needs to present program outcomes to city council. Which metric best demonstrates the environmental benefit of the program?
- Tons of CO2-equivalent greenhouse gas emissions avoided through recycling, compared to virgin material production (Correct answer)
- Total commodity revenue generated by the program in the fiscal year
- Number of residents who received recycling bins through the program
- Reduction in collection vehicle miles traveled compared to the prior year
Correct answer: Tons of CO2-equivalent greenhouse gas emissions avoided through recycling, compared to virgin material production
Greenhouse gas emissions avoided (using tools like EPA's WARM model) translates recycling tonnage into a concrete environmental impact metric that resonates with policymakers and the public.
Question 2: What is the EPA WARM (Waste Reduction Model) tool used for in recycling program reporting?
- Calculating greenhouse gas emissions reductions and energy savings associated with recycling, composting, and waste reduction activities (Correct answer)
- Estimating the market value of recovered commodities based on current prices
- Projecting future waste generation rates for long-term program planning
- Modeling MRF throughput capacity based on equipment specifications
Correct answer: Calculating greenhouse gas emissions reductions and energy savings associated with recycling, composting, and waste reduction activities
EPA WARM calculates GHG emissions reductions associated with specific recycling and composting activities, helping programs quantify their climate benefits using standardized emissions factors.
Question 3: Which recycling program report would be most useful for identifying whether contamination is worsening over time?
- Monthly contamination rate trend report showing percentage of prohibited materials in collected loads over consecutive months (Correct answer)
- Annual commodity revenue comparison against prior year
- Quarterly set-out rate report by collection district
- End-market rejection rate report filed by the MRF operator
Correct answer: Monthly contamination rate trend report showing percentage of prohibited materials in collected loads over consecutive months
A time-series contamination trend report reveals whether contamination is increasing, stable, or decreasing, and whether specific interventions (outreach campaigns, bin changes) had measurable impact.
Question 4: What information is typically included in a MRF's 'monthly operating report' to a municipal client?
- Incoming tonnage by material type, residue rate, commodity bales produced, outbound tons by material, and processing fee invoice (Correct answer)
- Market prices for each commodity sold during the month
- Number of employee hours and overtime costs for the period
- Equipment downtime incidents and maintenance costs incurred
Correct answer: Incoming tonnage by material type, residue rate, commodity bales produced, outbound tons by material, and processing fee invoice
Monthly operating reports give municipal clients the data needed to track program performance — tonnage in, material breakdown, residue generated, and what was sold and shipped to markets.
Question 5: What does 'program participation rate' measure in a recycling program evaluation, and how does it differ from 'set-out rate'?
- Participation rate measures the percentage of households enrolled in the program overall; set-out rate measures the percentage that actually put out their bin on any given collection day (Correct answer)
- Participation rate measures tons collected per household; set-out rate measures households that recycle correctly
- Participation rate is measured annually; set-out rate is measured weekly
- Participation rate applies to commercial programs; set-out rate applies to residential programs
Correct answer: Participation rate measures the percentage of households enrolled in the program overall; set-out rate measures the percentage that actually put out their bin on any given collection day
Participation rate captures overall enrollment or regular use of the program, while set-out rate is a per-collection-day metric showing immediate behavioral engagement — both are needed for a complete picture.
Question 6: A community's recycling diversion rate dropped from 28% to 22% year-over-year despite stable collection volumes. What is the most likely explanation?
- Total waste generation increased (more refuse generated), so diverted tons became a smaller fraction of total waste (Correct answer)
- The MRF's optical sorters were recalibrated and now sort more accurately
- Collection frequency was increased, reducing resident set-out rates
- A new commodity market opened, increasing demand for recyclables
Correct answer: Total waste generation increased (more refuse generated), so diverted tons became a smaller fraction of total waste
Diversion rate is a ratio — if the denominator (total waste generated) grows while diverted tons stay flat, the rate falls even without any decline in recycling performance.
