[GreenYes] Indoor composting economics: more details


Thanks to Mike Giuranna for a link to the City of Boston contact on this project.  Bryan sent out a quick reply, which I've included below.  It seems as though this is currently more in the idea stage than in formal development, and the City recognizes they need to deal with a host of issues before something like this is viable.
 
From Bryan:
 
Those are all issues we need to better understand before we actually go forward.  That's why we put out a Request for Expressions of Interest (RFI) which you can download from
http://www.cityofboston.gov/environmentalandenergy/  under Department Announcements.
 
We need to do a little more market research to know if this is the right move for Boston.  Our problem right now is that all the leaves come in at the same time and all the compost is ready at the same time, if we can process smaller batches more quickly, year round, find additional uses for leaf compost, and control odors and runoff, it may justify the capital expense, especially if we can include a biogas component that generates energy adn revenue.
 
Take a look at the RFI and feel free to get back in touch.
