Materials and Resources Flashcards
By-Product
A material, other than the principal product, generated as a consequence of an industrial process or as a breakdown product in a living system (EPA).
Certified Wood
Wood that has been issued a certificate from an independent organization with developed standards of good forest management. This certificate verifies that wood products come from responsibly managed forests.
Construction and Demolition Debris
Waste and recyclables generated from construction and from the renovation, demolition or deconstruction of existing structures. It does not include land-clearing debris such as soil, vegetation and rocks.
Construction Waste Management Plan
A plan that diverts construction debris from landfills through recycling, salvaging and reuse.
Regional/Locally Sourced Materials
Also known as regional materials, the amount of a building’s materials that are extracted, processed and manufactured close to a project site, expressed as a percentage of the total materials cost. For LEED, regional materials originate within 500 miles of the project site.
Recycled Content
The percentage of material in a product that is recycled from the manufacturing waste stream (preconsumer waste) or the consumer waste stream (postconsumer waste) and used to make new materials. For LEED, recycled content is typically expresse as a percentage of the total material volume or weight.
Post-Consumer Recycled Content
The percentage of material in a product that was consumer waste. The recycled material was generated by household, commercial, industrial or institutional end users and can no longer be used for its intended purpose. This includes returns of materials from the distribution chain. Examples include construction and demolition debris materials collected through recycling programs, discarded products (such as furniture, cabinetry and decking) and landscaping waste (such as leaves, grass clippings and tree trimming).
Pre-Consumer Recycled Content
The percentage of material in a product that was recycled from manufacturing waste. Preconsumer content was formerly known as postindustrial content. Examples include planer shavings, sawdust, bagasse, walnut shells, culls, trimmed materials overissue publications and obsolete inventories. Excluded publications and obsolete inventories. EXcluded are rework, regrind or scrap materials capable of being reclaimed within the same process that generated them.
Rapidly Renewable Materials and Products
The amount of a building’s agricultural products (fiber or animal) that are quickly grown or raised and can be harvested in a sustained fashion, expressed as a percentage of the total materials cost. For LEED rapidly renewable materials take 10 years or less to grow or raise.
Reuse
The amount of building materials returned to active use (in the same or a related capacity as their original use), expressed as a percentage of the total materials cost of a building. The salvaged materials are incorporated into the new building, thereby extending the lifetime of materials that would otherwise be discarded.
Salvaged Material
Construction items recovered from existing buildings or construction sites and reused. Common salvaged materials include structural beams and posts, flooring doors cabinetry, brick and decorative items.
Sustainable Forestry
Management of forest resources to meet the long-term forest product needs of humans while maintaining the biodiversity of forested landscapes. The primary goal is to restore, enhance and sustain a full range of forest values, including economic, social and ecological consideration.
Sustained-Yield Forestry
Management of a forest to produce in perpetuity a high-level annual or regular periodic output, through a balance between increment and cutting. (Society of American Foresters)
Waste Diversion
The amount of waste disposed of other than through incineration or in landfills, expressed in tons. Examples of waste diversion include reuse and recycling.
