[GreenYes] Re: rainfall affecting recycling tonnage

[Stephan Pollard <stephan.pollard@no.address>]

Paul,

If you are talking about the biasing affects of precipitation on weight 
measurements for a waste characterization there are a couple of papers 
that may be of interest  citations for which are listed immediately 
below.  If your are talking about the affects on participation rates 
I've not seen any peer-reviewed literature or research discussing this 
topic in any detail.

Sfeir, H., Reinhart, D., McCauley-Bell, P.R., 1999. An evaluation of 
municipal solid waste composition bias sources. Journal of the Air and 
Waste Management Association 49(9): 1096-1102.

Spendelow, P.H., 2001. Measuring recyclables in the waste stream: 
Improvements in waste composition study methodology. 17th International 
Conference on Solid Waste Technology and Management, Philadelphia, 
Pennsylvania, Journal of Solid Waste Technology and Management.

Stone, R., Kahle, R.L., 1972. Water and sewage sludge absorption by 
solid waste. Journal of Sanitary Engineering Division, ASCE 98(SA5): 
731-743.

Sincerely,
Stephan
