1 Why Waste Opportunities? Wednesday, October 18, 2017 (Winnipeg) Update on MEIA s New Home Construction Waste Diversion Study Mike Fernandes

2 Project Objective and Timing To complete a comprehensive analysis and operational pilot study towards assisting home builders to increase the diversion of construction waste from landfill. Phase 1 Baseline analysis and pre-feasibility study (2016/2017) Phase 2 Operational pilot study (2017/2018)

3 NON-RESIDENTIAL RESIDENTIAL Home Construction Waste Is Distinct Component of CRD CONSTRUCTION RENOVATION DEMOLITION 1. CONSTRUCTION waste from RESIDENTIAL sources includes scraps, ends and unusable cutoffs of new building materials, as well as discarded supplies, packaging and related wastes generated during the construction of new residential structures (single-family homes, multi-family homes, high rise apartments, low-rise apartments, cottages and seasonal homes). 4. CONSTRUCTION waste from NON-RESIDENTIAL sources includes scraps, ends and unusable cut-offs of new building materials, as well as discarded supplies, packaging and related wastes generated during the construction of new institutional, commercial and industrial buildings and structures. 2. RENOVATION waste from RESIDENTIAL sources includes a mix of both Demolition waste and Construction waste and occurs when repairs or enhancements are made to EXISTING residential structures. It includes both the old/used materials that are torn down, and the waste and scraps generated when new materials are put in their place. 5. RENOVATION waste from NON-RESIDENTIAL sources includes a mix of both Demolition waste and Construction waste and occurs when repairs or enhancements are made to EXISTING institutional, commercial and industrial buildings and structures. It includes both the old/used materials that are torn down, and the waste and scraps generated when new materials are put in their place. 3. DEMOLITION waste from RESIDENTIAL sources includes old building materials generated when residential structures that are no longer needed or wanted are torn down. It includes only the old/used materials that are torn down 6. DEMOLITION waste from NON- RESIDENTIAL sources includes old building materials generated when institutional, commercial and industrial buildings and structures that are no longer needed or wanted are torn down.

4 Phase 1 Objectives To establish a baseline (e.g., what materials are generated, how are they treated, options for treatment, who are the players, what are the markets, construction cycle). To understand: o o o o o the types and observed quantities of waste materials generated at new home construction sites (basic waste characterization analysis), how waste materials are currently being managed, how waste is being recycled, what waste is being landfilled and potential opportunities for diverting material from landfill benefits to current processes as well as barriers/challenges to diverting these materials; To ascertain the markets for waste construction materials; To identify the businesses reusing or recycling construction debris; To identify the waste streams associated with the different stages of the construction cycle;

5 Phase 1 Methodology Focused literature review - objectives-based, not academic exercise Interviews and ongoing dialogue with 2 homebuilders (Hilton Homes, Qualico Homes) and one land developer (Ladco Company Limited) Interviews with 2 waste haulers (Klippenstein Hauling, CastleStar Hauling) Research and interviews with local companies reusing, recycling, and/or diverting materials found in new home construction waste stream Site analysis, observations and on-site interviews with building crews at 8 sites in Bridgewater, Southe Pointe developments (SW Winnipeg) Study Set Square Footage Style Base Price (GST not included) Study Site two story $ 232,500 Study Site two story $ 251,900 Study Site one story $ 217,900 Study Site story (split level) $ 242,700 Study Site side-by-side (each unit two story $ 455,200 Study Site two story data not provided Study Site two story data not provided Study Site two story data not provided

7 Macroeconomic Factors Drive Overall Volume and Composition of New Home Construction Waste 1. The more homes being built, the more waste will be generated. 2. The larger the home, the more waste is generated during the building process. In 1975, average Canadian home was approx square feet. By mid-2000, the average size more than doubled to over 2300 square feet. In recent years, average new home size has dropped to 1,900 square feet. 3. Consumer preferences for customization, deviations from standard dimensions and variation in colors and design elements of homes being built also contribute to the volume and composition of waste generated.

8 Baseline Estimate of the Quantity of Waste Generated Through New Home Construction in Manitoba *Preliminary Phase 1 Findings* Kelleher, Perry, Robins Province of Manitoba (20%) Province of Manitoba (30%) USEPA1 Phase 1 Study Homes Final Results Phase 1 and Phase 2 Study Homes Average Kgs of Waste Generated Per Square Foot of New Home Constructed in MB to be completed in Phase 2 No further conclusions or interpretations of the preliminary findings should be made at this time. Phase 2 of this study will involve sorting and measuring waste from construction of new residential homes and will provide field gathered data for testing these preliminary estimates.

9 Illegal Dumping Nuisance & Cost

10 Wood-Frame Home Building Process 16 Stages 1. Planning, Design and Pre-Construction 2. Location, Excavation & Construction of Foundation and Footings 3. Framing of walls and sheathing of exterior (home is walled in aka dried in ) 4. Roof protective barrier and coverings (typically asphalt/fibreglass shingles) installed 5. Exterior wall coverings are installed 6. Installation of Heating, Ventilation and Air Condition (HVAC) systems 7. Plumbing pipes and water systems are roughed in 8. Electrical wiring and main and subpanels are roughed in 9. Interior of home fully insulated, interior walls and ceilings are drywalled 10. Walls, ceilings primed and painted 11. Interior doors, frames, door/window trim, and kitchen and bath cabinetry installed 12. Subflooring, floor coverings and baseboards installed 13. Lighting and electrical fixtures installed (i.e. finish electrical) 14. Toilets, showers, sinks, faucets and bath fixtures installed (i.e. finish plumbing) 15. Basement areas finished 16. Exterior features and add-ons (decks, detached garages, fences, walkways, etc. Different crews, different process, different materials, different supplies. Therefore, different mix of wastes generated at each stage.

17 Current Situation Waste Management At New Home Construction Sites Competitive and Fragmented Market with Multiple Participants Individually Negotiated, Unit-Based Service Contracts With Varying Fee Structures Individual Waste Collectors/Haulers Use Similar Approach but Different Equipment, Different Methods Space is extremely limited at building sites. Bins placement and re-positioning is challenge Minimal Separation of Waste, Loads Generally Collected and Disposed as Mixed Commercial Waste

18 Current Situation Waste Management At New Home Construction Sites Cost, Timeliness/Responsiveness and Ability to Keep Sites Clean are the Principle Competitive Drivers for Waste Haulers Haulers have had little success with past attempts to recycle/divert Waste Disposal Fees/Landfill tipping fees Are Significant and Growing Expense

19 Phase 2 Objectives To determine the amount of waste being generated and the amount being diverted, by construction material type; To quantify the potential costs and savings associated both with the current waste management processes and the diversion of construction waste (e.g., trucking, bins, tipping fees); To work with MHBA to determine and coordinate the logistics involved in reusing/recycling the different construction materials (e.g., number of bins, frequency of hauling, individual bins or multi-material bins, complications with existing contracts, site set-up); and To identify the overall opportunities for increasing diversion and barriers hindering diversion.
