        Project Objectives
• Complete a 12 month direct waste
  analysis of land-filled waste
• Establish empirical baseline data
• Perform a pilot study to:
  • Confirm sampling methodology
  • Ensure categories are comprehensive
  • Identify research constraints
• Begin full scale implementation in
  January of 2008
               Pilot Study
• October to December 2007
• Focus on development of methodology
  and sampling procedures
  • Residential waste generation
    • Front Street Automated
  • Other sources
    • ICI Sector: Shopping mall
    • Small Vehicle Transfer Station
        Pilot Study Results
• Nearly 62% of all waste sampled from
  October to December 2007 was:
  • Non-Meat Organics, Paper, Yard Waste
    and Other
• Monthly differences are primarily
  attributed to seasonal variability,
  including Fall Yard Work and
  Christmas Shopping

          Summary of Pilot
• Confirmation of sampling strategy
• Identified that the majority of land-filled
  waste in Regina could be diverted through
  recycling and composting activities
• More data analysis was required to identify
  the actual composition of each category
  relevant to diversion activities
• Slight alterations needed to be made to
  existing categories
  • Addition of a household hazardous category
   Full Scale Implementation
• Full scale sampling began in January
• Residential sampling occurs five times
  weekly
  • Inclusive of all residential collection types
• Small Vehicle Transport Station
  • 3 to 5 samples throughout the week
• ICI Sector
  • Targeted sources
  • Will increase in the upcoming months

  studies could be diverted through
  recycling and composting activities
           Looking Forward
Sampling
  • Continue sampling residential and small
    vehicle transport station
  • Increase ICI sector targeted sampling
Analysis
  • Neighbourhood generation rates
  • Comparative analysis of residential
    collection types
