  1. Tracking, Measurement and Analysis

  2. In This Lesson By the end of this lesson, learners will be able to: • (Knowledge Level) identify some of the key factors to measure when tracking and recording the cost of disposal and recycling practices • (Knowledge Level) describe the primary steps to perform a waste /recycling “right-sizing” • (Comprehension Level) explain what is meant by baseline data • (Comprehension Level) summarize how the results of the audit can be used to design program "next steps" and help eliminate wasting • (Application Level) Calculate diversion rates for various business models • (Analysis Level) examine the data from a waste audit and create a strategy for home/school/businesses to reduce or eliminate wasteful practices

  3. Tracking and Measurement Tracking and measurement is one of the most challenging aspects of showing the Zero Waste Picture • How well can you track and measure your program? • Do you have metrics in place to measure every aspect of your program? • What do you do with the information?

  4. Baseline Baseline = a minimum or starting point used for comparisons • Tons generated, disposed & recycled • Disposal costs, commodity sales revenue generated • Purchasing records (Qty & $)

  5. Look at Whole Picture Janitorial staff is often the least expensive Courtesy SBM

  6. Calculate Diversion Regular Diversion (Recycling) Zero Waste Diversion Uses total generation + estimated waste reduction How do you measure something that wasn’t generated Incentivizes upstream redesign and waste reduction Provides full picture of Zero Waste initiatives • Uses total generation • Provides a limited view of Zero Waste initiatives • Incentivizes downstream recycling and reuse

  7. Example: How to Calculate Diversion of Generated Materials

  8. Example: How to Calculate ZW Diversion of all Baseline Materials

  9. Calculate a diversion rate and Zero Waste diversion rate for a sample company. What does the example show? Why is it important to look at the whole picture?

  10. How Do Businesses Throw Away Money? • Businesses pay for collection each time the bin is services…and most businesses over subscribe for trash service • Businesses pay when empty and partially full bins are dumped • Un-flattened cardboard boxes and bags of air, waste bin space • It costs to dispose of recyclables in the trash

  11. How to Right-Size Trash Services • Collect baseline data for trash and recycling services • # bins • # pick-ups per week • Size of bins • Get rates for various alternative levels of service • Obtain waste conversion chart • Create data forms

  12. Example Trash Service Data ACME Student Cafeteria • 3 dumpsters • 3-cubic yards each • Picked-up 1 x week each on Wednesday afternoon • $842.19 / month for trash collection Do we have enough data? When should we audit?

  13. Sample Rate Matrix

  14. Estimate Actual Volume of Trash Disposed Visual Inspection • Do a visual inspection of the bins when bins are most full prior to collection Wednesday Morning • Bin #1–Assume 100% full. Cardboard boxes make up about 75% of the bin and they are not flat. Trash bags makeup the other 25% • Bin #2 – 50% full with only cardboard boxes that are not flattened. • Bin #3 – A couple loose bags of trash. Assume the bin is 25% full.

  15. ❶ Size of bin in cubic yard ❸Estimate how full the bin is in % ❺% of each material type based on total volume ❺ Below dashed line multiply ❶ x ❸ x ❺ to get cubic yards per day of each material type ❼Add columns to get total weights per day

  16. Conversion Chart

  17. Analyze the Data • Use accurate conversion tables • Do your estimates in both weight and volumetric measurement • Review rate matrix • Pay attention to data that seems inaccurate • Look for data that you weren’t expecting

  18. Analyze the Data

  19. Right-Sizing Benefits • Cost Reduction = $701.83 • Recycling diversion was 0% now = 68% • Reduction in total # of bins onsite (property space has a value) • Potential for fewer truck trips • Better understanding of what’s still in trash • …next steps

  20. More Right Sizing

  21. Complete the worksheet example on right-sizing. • What are the key outcomes?

  22. Information to Action • Use the gathered data to implement reduction, reuse and recycling strategies

  23. Sierra Nevada Brewery Working toward Zero Waste goal Diversion stagnated Needed to identify next steps and materials still being disposed

  24. Composition by Weight Composition by Volume Compare Weight –vs-Volume

  25. Review the Rate Matrix

  26. Look for Opportunities • What are the next steps? • Is there low hanging fruit? • Most volume • Most value • What are the problematic materials? • Most toxic • Where are the service gaps?

  27. Track • Track weights • Track volume • Track cost • Track rebate • Track quantity • TRACK IT ALL!

  28. Let’s bring this lesson together by doing one last activity. • Looking back at exercise #2, provide at least one scenario for improvement. (look upstream, look at costs, look at options)
