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 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
