Construction and Demolition Waste Management at UVM
Construction and Demolition Waste Opportunities
• Construction and demolition waste is 20-40% of the waste stream going to landfills nationally
• C+D waste is being generated at UVM everyday; we estimate there are nearly one hundred active projects on campus on any given day.
Environmental Impacts
• Landfill leaks
• Methane gas generation
• Energy lost by not recycling / re-claiming materials
• Transportation: greenhouse gas emissions
Definition of C&D Waste
“Waste material that is produced in the process of construction, renovation, or demolition of structures. Structures include buildings of all types (both residential and non-residential) as well as roads and bridges. Components of C&D debris typically include concrete, asphalt, wood, metals, gypsum wallboard and roofing”.
-EPA
Key Terms
• Construction waste- waste generated while constructing a new building or structure
• Demolition waste- waste generated while taking down an existing building or structure
• Deconstruction- the taking apart of an existing building so that materials can be re-used elsewhere
Typical C&D Wastes
• Asphalt, Asphalt Shingles
• Carpet
• Carpet padding
• Clean wood/pallets
• Concrete
• Corrugated cardboard
Typical C&D Wastes
• Gypsum (drywall)
• Land clearing debris
• Scrap metal
• Salvage
• Other…
Requirements at UVM
• Major projects: new buildings, major renovations
• Minor projects: short term or partial building projects
• Ongoing renovations: Physical Plant routine maintenance and renovation
Requirements at UVM
• The waste management plan will be based on LEED® guidelines for C+D waste management
• The plan must divert at least 50% of waste generated from the project
• Workers must view training presentation as part of job site orientation
C&D EMS
• Focuses on continuous program improvement by organizing activities into four stages:– Plan
– Do
– Check
– Act
• Program documentation is to maintain program improvements over time
• This approach is based on organizational quality improvement practices
C&D EMS
• Plan: vendor identification, development of job specifications
• Do: walkthrough checklist, collection of disposal tickets
• Check: entering of disposal data into the system, meeting of LEED goals
• Act: evaluation of program by project managers, analysis of financial impacts
C&D EMS
• Plan: tri-annual review of vendor options and specifications
• Do: implement the project tracking system for all major projects and move the size of the projects covered smaller and smaller
• Check: assure C&D waste LEED points are achived for every project (50% recycled for 1 point; 75% for 2 points) plus innovation point
• Act: financial break even compared to landfilling the entire job
LEED Requirements
• The Leadership in Energy and Environmental Design (LEED®) Green Building Rating System is the nationally accepted benchmark for the design, construction and operation of high performance green buildings.
• It gives building owners and operators the tools they need to have an immediate and measurable impact on their buildings’ performance, by promoting a whole-building approach to sustainability.
LEED Requirements
• LEED certification is required for large projects at UVM – According to the 2007 “Environmental Design in New and Renovated Buildings”
Policy, UVM projects must achieve 33/69 points to achieve the required ‘Silver’ rating.
• In the LEED-NC 2.2 Rating system, there are 2 points available for Construction and Demolition waste diverted from the landfill:– 1 point if 50% of waste is diverted
– 2 points if 75% of waste is diverted
• The UVM tracking tool collects and reports the information that must be submitted to receive these points.
LEED Criteria
• MR Credit 2.1: Construction Waste Management: Divert 50% From Disposal: 1 Point – Recycle and/or salvage at least 50% of non-hazardous construction and
demolition debris. – Develop and implement a construction waste management plan that, at a
minimum, identifies the materials to be diverted from disposal and whether the materials will be sorted on-site or co- mingled. Excavated soil and land-clearing debris do not contribute to this credit. Calculations can be done by weight or volume, but must be consistent throughout.
• MR Credit 2.2: Divert 75% From Disposal: – 1 Point in addition to MR Credit 2.1 – Recycle and/or salvage an additional 25% beyond MR Credit 2.1
• Additional points for using salvaged and/or recycled content building materials
Demolition/Deconstruction and New Construction Required Elements
• Collection containers must be on site and labeled clearly before demolition can begin
• Waste must be separated into appropriate categories
• Labeled bins will remain on site for waste generated in new construction
• All waste shipped off-site must be tracked in C&D database
