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 Rebate for sale of commodities
Look at Whole Picture Starting Point Total cost Total tons Labor Costs Staff time to collect, transport and bale Hourly staff loaded rate Equipment and Hauling Costs Cost for equipment Cost for hauling, disposal Material Values Rebate for sale of commodities Janitorial staff is often the least expensive Courtesy SBM

6 Calculate Diversion Regular Diversion (Recycling) Zero Waste Diversion
Uses total generation Provides a limited view of Zero Waste initiatives Incentivizes downstream recycling and reuse 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

7 Example: How to Calculate Diversion of Generated Materials
Trash/Landfill/WTE amount (all tons) 21.2 Recycle 96.1 Reuse 12 Total Generation = 129.3 Diversion Rate (Recycle + Reuse) / (Total Generation) / 129.3 = 83.6%

8 Example: How to Calculate ZW Diversion of all Baseline Materials
Trash/Landfill/WTE amount (all tons) 21.2 Reuse 12 Recycle 96.1 Reduction 15 Total Generation = 144.3 ZW Diversion Rate (Reduction + Recycle + Reuse) / (Total Generation) / 144.3 = 85.3%

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 $ / month for trash collection Do we have enough data? When should we audit?

13 Sample Rate Matrix

14 Estimate Actual Volume of Trash Disposed
Bin Size % Full % Trash C.Brd TOTAL Per Week 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.

16 Conversion Chart Weights per CU Yard Converged 2013 EPA 1993

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 Trash Cardboard 1.5 CY week 3.75 CY week
Optimal Trash Service Level: One 1.5-cubic yard 1 x Week Optimal Recycle Service Level: One 4-cubic yard 1 x Week Cost Per Month = $140.36 = $0 Conversion = lb/CY Conversion = lb/CY 1.5 x x 52/12 = 744 lb/month 744 / 2000 = .372 Tons per Month 3.75 x 100 x 52/12 = 1625 lb/month 1625 / 2000 = .81 Tons per Month

19 Right-Sizing Benefits
Before After Level of Trash Service  39 CY / month for Trash only  6.5 CY / month for Trash  Cost $ / month  $ / month  Recycling None 16CY / month # of Bins 3 total for trash only 2 total / 1 each trash and cardboard 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
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

28 Compare Weight –vs-Volume
Composition by Weight Composition by Volume

29 Review the Rate Matrix

30 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?

31 Track Track weights Track volume Track cost Track rebate
Track quantity TRACK IT ALL!

32 Let’s bring this lesson together by doing one last activity
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)
