Diverted vs Commingled in LEED Online Form

Dionisio, Im not sure i understand your question,  but Generally, commingled waste is when you leave recyclables mixed on site and a recycling company will take everything from your site and will track percentages for each waste material.  Generally pursued by projects which don't have enough space for on site separation.   The other strategy is to separate on site and perhaps have different recycling companies for different waste materials.  You can pursue the option that is best suited for your project. And yes separating on site wont do, you have to demonstrate the diverted waste reaches a satisfactory final destination (recycling facility). 

Dionisio - Yes - you can use commingled and less than 100% and put the non-recycled delta in as landfilled waste. Another way to address where some of the separated or commingled material is actually landfilled waste is to include that portion as landfilled waste. Then subtract that landfilled portion from the "diverted" total and report all that is actually diverted as 100%. Either way - have good back up. And remember that if you use commingled you have to provide back up as part of your submitted documentation.
