for reporting waste generation and diversion

The origins of gap

The origins of GAP

  • Strathroy, Ontario - contract awarded on basis of very high diversion percentage (>90%)

  • Contractor who did not win launched suit

  • Key question became “what does a particular diversion percentage mean?

  • CSR - volunteered to set up a committee to address issue


Why csr spearheaded development of gap

Why CSR Spearheaded Development of GAP

  • CSR objective - develop and promote cost effective recycling and waste management systems

  • Good data is the key to optimizing waste diversion systems

  • CSR recognized the need for a national approach to data reporting

  • GAP was established to identify a good method to collect good waste diversion and disposal data


Gap vision

GAP Vision

  • GAP stands for Generally Agreed Principles

  • Purpose of GAP for waste flow is to develop a common reporting framework which allows municipalities across Canada to compare diversionof residential waste management systems

  • GAP started with RESIDENTIAL waste, moved on to ALL MUNICIPAL WASTE at request of Kootenay Boundary


Why gap

Why GAP?

  • Locally defined rules – diversion reporting was often politically or economically driven

  • Municipal search for higher diversion/ lower cost systems requires high quality information

  • Needed consistent reporting approach

  • No ‘right or wrong’ methods- but need consistency

  • Needed a consensus approach to a common methodology that everyone would buy into


Benefits of gap to users

Benefits of GAP To Users

  • Debunks ‘myths’ about other municipalities are doing better than you

  • If municipal reports do not use GAP, you do not know if their numbers are ‘real’ or not

  • Require others to use GAP to compare to your municipality

  • “Apples to Apples” is essential for transparency


Some gap comparisons 2003 2004

Trois Rivieres, PQ 12%

Regina, Sask 16%

Winnipeg 18%

Calgary 19%

Banff 24%

Toronto 31%

Whitehorse 32% (all municipal)

Guelph 38%

Kootenay Bdy 39% (all munic)

St. Thomas 45%

Seattle, Washington 46%

Ottawa Valley 54%

Halifax 56%

Some GAP Comparisons 2003/2004


Benefits of gap to users1

Benefits of GAP To Users

  • Common framework to collect, report and summarize waste management information

  • Good guide to putting simple data collection systems in place

    • After systems in place, easy to do annual updates

  • Good monitoring tool to measure performance of diversion systems from one year to the next

  • Good method to keep your neighbours honest

    • (apples to apples)


The gap team national and multi stakeholder

The GAP Team - National and Multi-Stakeholder

  • Municipal

    • Kootenay, Calgary, Winnipeg, Toronto, Guelph, Halifax

  • Provincial and Federal Government

    • BC, Alberta, Ontario, NS

    • Env Can, Statscan, NRCAN

  • Industry and Stewardship Organizations

    • MPSC, CSQ, Clorox

  • NGOs and Associations

    • AOMGMR (Quebec) RCA, Canada Composting Council


Concept and approach

Concept and Approach

  • Keep it simple

  • Collect minimal amount of data

  • “Entry level” data collection tool

  • Put all summary municipal data on one page; GAP data creates a GAP Chart

  • Started with faxed forms in 2000; moved to Excel format by 2001

Summary Statistics


Data needed for gap

Data Needed For GAP

  • Population, households

  • On-site management:

    • Backyard composters;

    • Policies on grass-cycling;

    • Organic waste collected in aerated carts;

    • Estimates of open burning/burning in fireplaces

  • Curbside recyclables, organics, garbage

  • Drop off recyclables, organics, garbage

  • Residue rates at MRF and composting site


  • Special collection and drop off data categories

    Recyclables

    just one category

    Xmas trees

    Source separated organics

    Leaf and yard waste

    Bulky

    white goods

    Scrap metals

    Tires

    HHW(HSW)

    C&D

    Other

    Garbage

    Special Collection and Drop-Off Data Categories


    Default values in gap

    “Default” values in GAP

    • 100 kg per backyard composter per year

    • 36kg/cap for garburators per year

    • Diversion in GAP is “net of residue” – an incentive to reduce residues

      • Residue default values set at rate to encourage better measurement

      • Municipality can use their own data, but must show source

    • 5% for MRF residue rate (2-stream)

      • Increased to 12% to 15% for single stream recycling

    • 20% for composting residue rate


    Diversion in gap

    Diversion in GAP

    • Deposit, return and stewardship programs automatically calculated per capita for each province

    • Re-use (managed by municipality)

    • Backyard composting, grass-cycling,

    • Evapotranspiration (aerated carts only)

    • Garburators (if biosolids diverted)

    • HSW re-use and recycling

    • Recyclables diverted

    • Organics diverted


    R ecovery and d isposal in gap

    Recovery and Disposal in GAP

    • EFW mass reduction is defined as recovery

      • Allows jurisdictions which track recovery separate from disposal to show separately

      • Most Canadian jurisdictions count EFW mass reduction as disposal

    • Solid and hazardous waste landfill is counted as disposal


    Beneficial use in gap

    Beneficial Use in GAP

    • Benefical Use Committee 2004 tackled a number of issues

    • Definition of “beneficial use”;

      • Applied mostly to tires, glass, low quality compost, chipped wood

    • How to address material use within landfill boundaries

      • Should glass for roadbed construction, etc. be counted as a lower value than glass returned to glass manufacture

    • Are all “beneficial uses” considered diversion


    G ap status in 2004

    GAP Status in 2004

    • Decisions on GAP approach and rules made by National multi-stakeholder team

      • Rules change over time

      • Meetings every three months by conference call

    • 40 communities in Canada had GAP charts on CSR website

    • 15 UK GAPs on website

    • Designed process to generate GAP chart automatically from Ontario “Datacall” process

    • GAP envisioned as permanent ‘work in progress’,

      • would continue to evolve with more municipal input


    Gap status in 2010

    GAP Status in 2010

    • Statistics Canada added GAP to bi-annual reporting 2006

    • National GAP Committee no longer active as of 2004

    • Ontario adopted GAP for municipal benchmarking and performance reporting 2001

    • WDO adopted GAP for diversion and disposal reporting 2005

    • 2006/2007 WDO developed verification protocols

      • “Tests” to ensure reported numbers reasonable

      • “default values” for cases where data not measured

    • GAP diversion value for 200 municipalities posted on WDO website annually based on Datacall results
