I just wanted to reiterate my support for eliminating ADC as "recycling." I operate a co-mingled construction waste recycling facility and I am fully aware that ADC is a nice tool to get projects above 75% when the recovery rates are borderline. Getting rid of it will be a challenge for me and other recyclers but it is one that we can overcome.
The big problem that needs to be addressed is that some landfills are burying 100% of a project's construction waste but claiming a 90% recycling rate since anything that doesn't blow away in the wind can be considered ADC. "Processing" in this case becomes running over the material with a compactor, the same thing they do with regular waste. This ADC loophole has made a mockery of the system and it needs to be fixed. Getting rid of ADC altogether is the best approach as it is clean, simple, and in line with what people expect when they hear the word "recycling." Burying wood, metal and concrete in a landfill on top of regular trash instead of mixing it in is not recycling -- ADC should not be considered recycling.
