Stephan: 1. food waste generation -- at least at the residential level -- is generally examined via more or less sophisticated waste characterization studies based on what is collected; there's a body of work on this topic out there -- the NYC reference is to a highly sophisticated, 90+/4-season sort for which the final report is due any day....Tim may have more on what is generated, prior to selection of disposal/management options.... At the commercial level, there's some research available, but obviously varies tremendously by type of food-service establishment, size, etc. 2. re the second question, check out the UW/Life Cycle Analysis study....the exec summary is on www.insinkerator.com; the full report is available upon request. Also, the 2004 Delft study, as I recall -- the update of an earlier one -- examined the 'diversion/capture' rate of participants in local source-separated organics collection systems.... 3. the 'penetration rate' of residential disposers is probably regarded as proprietary information, and I'm not aware that Census data is helpful at that level... on an anecdotal basis, I recently randomly queried @ two dozen new high-rise developments in Philadelphia, and found more than half were installing disposers....(which doesn't mean the others weren't)...in NYC, perhaps half of the major residential disposers are now including as a standard.... I would, however, be interested in some research help on that score; for example, my random queries of 'green' multi-family buildings around the country find that disposers are generally installed -- albeit w/out much thought one way or the other....but would welcome a more rigorous examination of that question... More?

I, and perhaps others, would much appreciate citations of any scientific literature, peer-reviewed or otherwise, detailing research in these areas including discussion of the representative nature of any undertaken samplings and the extrapolation of research findings to broader populations.
