buidling waste recycled to generate energy (power/heat)

I haven't tried this (commonly called waste-to-energy in the U.S., or simply incineration, and generally has a negative reputation environmentally here), but I think it has zero percent chance of working in LEED with MRc2.The MRc2 credit intent clearly states that the point of the credit is to divert waste from the landfill or from incineration.

yes, we tested this via CIR as well as a true "waste to energy" approach, not incineration. It was rejected. Neither USGBC or GBCI can differentiate the difference between WTE and incineration. True WTE is tightly controlled by the USEPA as far as emissions and the carbon footprint analysis in most instances indicates a lower impact than landfilling. There is significant work being done across the US in WTE and the State of Kentucky is showing real leadership; worth checking out. CWM is far more than just recycling and must be comprehensive in order to be effective. WTE can be part of a more comprehensive approach and may ultimately be a viable soluton for many urban centers that are rapidly running out of acceptable areas for landfills (if there is such a thing)

Waste to energy creates lots of dirty air. I believe it is significantly worse than burning clean wood- think of all the plastic and paint that can be in your trash. Wood derived fuel has to be clean wood. Look up the emissions rates for trash to energy plants. It's not really something they want to encourage even if it does spare landfill space.

Interesting that waste-to-energy can potentially be included in LEED v4. From MR credit Construction and Demolition Waste Management's requirements: "However, for projects that cannot meet credit requirements using reuse and recycling methods, waste-to-energy systems may be considered waste diversion if the European Commission Waste Framework Directive 2008/98/EC and Waste Incineration Directive 2000/76/EC are followed and Waste to Energy facilities meet applicable European Committee for Standardization (CEN) EN 303 standards." LEED 2009 teams can use the LEED v4 Construction and Demolition Waste Management prerequisite and credit - http://www.usgbc.org/articles/use-v4-credits-your-v2009-project - as a substitute for CWM credit.
