Re: Foundry Wastewater slude



Dave:

You should contact Elizabeth Olenbush, Director of the 
Foundry Industry Recycling Starts Today (FIRST) 
Project.  FIRST is actively involved in precisely the 
types of matters to which you refer.  I know that Kurtz 
Bros., Incl [Independence, Ohio; (216)986-7000] is doing 
things with foundry waste materials, and Hamilton 
County, Ohio is using flowable fill in some of their 
programs (Contact: William Brayshaw, Chief Engineer, 
Hamilton County; [(513)946-8902]).  In Michigan, you 
might check with Dave Walborn, Resource Recovery Corp. 
of West Michigan [(616)837-1885].  They are working with 
these approaches in Michigan. 

You may already know about these connections, but I 
thought I should pass them on.  I would urge you to 
contact Elizabeth Olenbush (413)229-2466.  Ohio (through 
the Ohio Cast Metals Association; Russ Murray, Exec. 
Dir. [614)876-5100]is a partner in FIRST and Elizabeth 
has done a lot of work with Ohio in these programs.
