MR 4.1 & 4.2

MR 4.1

Recycled Content

10% (post-consumer + 1/2 pre-consumer)

Use materials with recycled content that constitutes 10% of the total value of the materials in the project

PTS-1

MR 4.1 Requirements
Use materials, including furniture and furnishings, with recycled content such that the sum of post-consumer recycled content plus 1/2 of the pre-consumer content constitutes at least 10% of the total value of the materials in the project

MR 4.2

Recycled Content

20% (post-consumer +1/2 pre-consumer)

Use materials with recycled content that constitutes 20% of the total value of the materials in the project.

PTS-2

MR 4.2 Requirements
Use materials, including furniture and furnishings, with recycled content such that the sum of post-consumer recycled content plus 1/2 of the pre-consumer content constitutes at least 20% of the total value of the materials in the project.
What division is supposed to be in the calculation?

Div 12- Furniture

When a project team has purchase components that have recycled contents outside a ____ range of those used in manufacturer’s published percentages for the typical configurations, they will need to obtain project specific detail.
5%

For steel products where no recycled content information is provided, assume the recycled content to be ______.

25% post-consumer
_____ however may be included at the discretion of the project team. If _______ are included for this credit, they must also be included in the denominator for MR Credit 5, Regional Materials.
plumbing products
Assembly Recycled Content
includes the percentages of post-consumer and pre-consumer content.; The determination is made by dividing the weight of the recycled content by the overall weight of the assembly.
Net Project Material Value
is determined for a credit based on those material components to be considered in determining the percentage earned.; It is the denominator of the calculation.; For LEED CI MR Credits 4.1 and 4.2 the Net Proejct Material Value includes the Construction Material Vaule and the Division 12 Material Value, less the material value of mechanical and elelctric components and the salvage value identified in LEED for Commercial Interiors MR Credits 3.1,3.2,3.3.; The material value of plumbing, to the extent included in the numerator, must be included in the Net Project Material Value.
Post- Consumer
recycled content is consumer waste that has become a raw material (feedstock) for another project.; It originates from products that have served a useful prupose in the consumer market.; Much of this feestock comes from residentail and commercial recycleing programs for aluminum, glass, plastic and paper.; Other post-consumer feedstock is supplied by businesses that recycle construction and demolition debris.

Pre-Consumer

content, previsoulsy referred to a Post-Industrial Content, is output from a process that has not been used as part of a consumer product, that is sold, traded, or exchanged under commercial terms (including auditable transactions between profit centers within an organization) as feedstock for another industrial process, and that world otherwise be landfilled, incinerated or somehow disposed of as waste, as defined by the Federal Trade Commision.; For instance, a composite board manufactuere may purchase (or haul away for free) sawdust from a lumber mill or waste straw from a wheat farm.; Wood chips would not fit this definition.
