$4 per cubic yard. For analysis purposes, an average product price of $3 cubic yard was
used (Wilde, interview). Due to the fact that the sediment is approximately 50% water,
two cubic yards of dredged sediment will yield one cubic yard of end-use product. As a
result, the revenue that is generated by processing one yard of dredged sediment will be
approximately $1.50. Taking into account the tipping fee, the processing costs, and the
market price of the end-use product, Biogenesis will earn a net profit of roughly $4.50
per cubic yard, as shown below Figure 4.

The Integrated Plasma Gasification and Combine Cycle (IPGCC) devised by the Solena
Group, Westinghouse‘s strategic partner, for the decontamination of sediment consists of
three major steps: preprocessing, vitrification, and offgas treatment. Preprocessing
consists mostly of sediment sorting and dewatering. The actual decontamination of the
sediment takes place through vitrification, or heating the sediment to sufficiently high
temperatures to transform it into a glass-like product.
As shown in the schematic in Appendix B, pre-processing begins with screening the
contaminated sediment twice: the first time to remove oversized materials and the second
to remove larger pieces of sediment. The oversized material can be disposed of in a non-
