Requirements

4.1 Use materials with recycled content such that the sum of post-consumer recycled content plus

one-half of the pre-consumer content constitutes at least 10% (based on cost) of the total value of

the materials in the project. (4.2 Use materials with recycled content such that the sum of post-consumer recycled

content plus one-half of the pre-consumer content constitutes an additional 10% beyond MR Credit 4.1 (total of

20%, based on cost) of the total value of the materials in the project)

The recycled content value of a material assembly shall be determined by weight. The recycled

fraction of the assembly is then multiplied by the cost of assembly to determine the recycled

content value. 

Mechanical, electrical and plumbing components and specialty items such as elevators shall not

be included in this calculation. Only include materials permanently installed in the project.

Furniture may be included, providing it is included consistently in MR Credits 3–7.

Recycled content shall be defined in accordance with the International Organization of Standards

document, ISO 14021—Environmental labels and declarations—Self-declared

environmental claims (Type II environmental labeling).

Post-consumer material is defined as waste material generated by households or by commercial,

industrial and institutional facilities in their role as end-users of the product, which can no longer

be used for its intended purpose.

Pre-consumer material is defined as material diverted from the waste stream during the

manufacturing process. Excluded is reutilization of materials such as rework, regrind or scrap

generated in a process and capable of being reclaimed within the same process that generated it.
