Evaluation of Composting Implementation
Abstract
The primary regulatory issue effecting the cost of treatment is whether RCRA regulations apply to these sites. If it is determined that Superfund (CERCLA) regulations or state regulations are applicable, then cost savings may result. This is because these regulations are based on protection of public health, welfare and the environment or risk based standards and take into account site specific issues relating to the location of the contaminated soil and the location of the treatment and disposal of these soils. Facility components effected by the regulatory framework include the use of concrete pads and liner systems, run on/run off water management, security, permitting, monitoring and facility closure. Optimization of the composing technology can also have a significant effect on treatment costs. A variety of optimization strategies were evaluated including microbial kinetics, amendments, pretreatment, bioenhancement, surfactants, fungal treatment and alternative designs. The most significant cost savings can result if the quantity of amendments used in the process are reduced. There are nearly a direct relationship between amendment usage and unit treatment cost. This is due to improved throughput in a given size facility (or conversely reducing the facility's size) and not simply the savings associated with amendment purchase.
