Don’t confuse “recycled content material” with “material reuse”; the two terms have very different meanings:

Recycled Content is material containing recycled content as a result of the industrial process of making the product—for example; recycled-content carpet may be made of post consumer recycled plastic bottles. 

Material Reuse is the use or repurposing of material from a previous place or role—for example, buying antique wood doors salvaged from an old church. 

MRc3: Material Reuse and MRc1: Building Reuse are often confused when salvaged materials are recovered from the demolition of a project site. 

MRc3: Material Reuse can involve material that is salvaged onsite and used again onsite for another purpose or in another location. The onsite salvaged material will count towards both MRc3: Material Reuse. For example, if a project demolishes a building and saves all the wood doors, then turns the salvaged doors into countertops for the new construction, the salvaged doors count toward MRc3: Material Reuse.  

MRc1: Building Reuse can involve preserving part of a building or a material onsite and reusing it for its original purpose, or leaving it in its original location. The preserved portion of the building, or the material, only counts toward MRc1: Building Reuse (but not toward MRc3: Material Reuse or MRc2: Construction Waste Management). For example, if a project demolishes part of an existing building, leaving all interior walls with the existing doors intact to be used for the new building, the doors count only as building reuse.
