A brief description of programs, policies, infrastructure investments, outreach efforts, and/or other factors that contributed to the diversion rate for construction and demolition waste:

For Carleton's Weitz Center project (completed Sept 2011) the contractor tracked waste for LEED requirements. For that project, total Waste (2010-2011) was 7136.40 tons of which 6592.89 tons were recycled/re-used ( 92% )

Calendar year 2011 Waste for the Weitz Center project was 640.37 tons of which 558.46 tons were recycled/re-used (87%)

The large amount of demolition (1954 classroom wing and 1934 auditorium balcony) occurred in 2010 and boosted the overall material recycling.

2017-2019 included the demolition of Mudd Hall and beginning construction of a new science building. This is reflected in the large amount of recycled C&D that increased from 980 tons to 7,485.32 tons of material. The project is tracking to be a LEED Platinum building.

Additional documentation to support the submission:

For non-LEED projects, we do not currently have data on construction and demolition materials that have been recycled, donated or otherwise recovered. The last major campus construction project, Anderson Hall, requires a certain percentage of construction waste to be recycled, donated or otherwise recovered via LEED.
