Goldberg General Contracting
case study is one in a series developed by Illinois Sustainable Technology
Center at the University of Illinois to highlight techniques for saving money
and protecting the environment through reuse and recycling of construction and
demolition debris. Goldberg General Contracting was the lead contractor for the
two-story 2,675 square foot home that was built to LEED- H Platinum
requirements. The home incorporated a variety of site-related green products
including 100% pervious paving, two green roofs, solar panels, and a zero-turf
landscape design. Due to the site restriction, it was not possible to have more
than one roll-off box on site. As a result, the builder contracted with a
recycling facility for hauling and recycling of commingled waste, which, with
the exception of food waste, could all be placed in a single roll-off box. The
commingled construction waste was hauled to the recycling facility for material
sorting and recycling. The major advantages to commingling construction waste
are that trade contractors do not need to alter their job-site practices, which
in turn eliminates the need for (a) recycling signage and associated costs, (b)
training trade contractors and delivery personnel as to site recycling
practices, and (c) monitoring the roll-off box for content contamination.
Goldberg General Contracting recycled or reused 34.10 tons of the 38.92 tons of mixed construction and demolition waste generated for a waste reduction of 87.64%. Only 4.82 tons of waste material was hauled for landfill--the equivalent of one of the 12 roll-off boxes hauled from the site. Through recycling, the site was able to save $736 when recycling benefits and the avoided disposal costs were combined.
