Brief History of Ash Reutilization
When RAM began, Davidson and Sumner Counties incinerated much of their solid waste. RAM’s efforts to end this included education sessions which explained the Davidson County system clearly. Following a pilot in Sumner County, in late 1993, Davidson County began paying American Ash Recycling Corp. of TN (AAR) to distribute treated incinerator ash as loose construction fill material. RAM objected. RAM's documentation was sought by environmental groups in many states. Tired of this, AAR sued RAM in early 1997. This forced RAM to investigate further. This led to discoveries which ultimately led Davidson County to end both incineration and its use of AAR. RAM showed that loose, treated incinerator ash, used as construction fill, would make harmful contents more available to soil life than AAR’s submitted health risk assessment modeling had assumed.
