10 Draft Integrated Waste Management Plan - City Council - City of ...

2012 Davis Integrated Waste Management Plan
The City did ask for permission to use CalRecycle grant funds to print these shopping lists. While the City’s
grant manager was impressed by the idea and commended the City for its originality, permission was not
granted as the shopping list did not meet the requirements for grant expenditures (see section 8.1.4 on grants).
The City printed these in June 2012 using printing and outreach funds remaining at the end of the fiscal year.
These funds may not be available in subsequent years.
All these outreach activities require funds for which the Recycling Program does not have grant money and
would have to be budgeted for out of the Recycling Program fund.
9.2.2 Deconstruction
The City of Davis actively promotes the recycling of construction and demolition materials through its C&D
ordinance (see section 7.6). Another option for dealing with demolition waste is deconstruction.
Each year, as many as 100,000 residential buildings are demolished in the United States. This represents more
than 8 million tons of wood, plaster and drywall, metals, masonry, and other building materials, much of which
end up in local landfills.
Typically, when a building is taken down, heavy equipment is used in demolition. All parts of the structure are
reduced into rubble, wood, masonry, metals, and other materials. These materials may be sent to a C&D sorting
facility, where the materials are recycled. Most C&D facilities can recycle 50% or more of “mixed C&D
waste,” but the materials are typically “down-cycled” and converted into new materials or products of lesser
quality and reduced functionality. Lumber is often ground up for mulch or composting; concrete, rock and
brick are crushed for use as fill, etc.
Deconstruction is the selective dismantling of materials from buildings before, or instead of, demolition.
Through deconstruction, materials may be salvaged for reuse or recycling. Some salvaged materials, such as
wood flooring, ornate trim, bricks, electrical and plumbing fixtures, may retain to up to 75% of the items’
original value.
CalRecycle supports deconstruction and is working with contractors, engineers, architects, and local
governments to encourage this method.
DRAFT
The City has been approached by a local branch of a non-profit group that offers deconstruction services.
A deconstruction program may be implemented without a significant cost expense, but staff time will be
required to investigate all aspects of such a program (permits required, certifications, requirements and outreach
implantation).
Several options are available for the City in regards to setting up a deconstruction program:
Create a deconstruction webpage on DavisRecycling.org
o List local contractors that offer deconstruction services
o List step-by-step process of a deconstruction project
Create a flier on deconstruction, post online and have copies available at the Community Development
and Sustainability Department front counter for people when they come for building permits.
List deconstruction options on the online Recyclopedia
Update the C&D ordinance to include deconstruction options.
