Harry Hayes, Director of Houston Solid Waste, joins us by phone to talk about progress with the new single stream pilot program.  Director Hayes says it's a clear success, already in 10,000 households, with plans to reach an additional 50,000 of Houston's 375,000 households.  But between the lines, it sounds like the program is struggling to find funding.  Why is recycling expected to earn its keep?  No other municipal program is.
