Additional Factors That Affect Processing Costs

• Concentration level and range of contaminants in
  sediment
• Volume of sediment to be treated (i.e. project
  size or long term supply)
• Local market (volume/value) for beneficial use
  products

Advantages Disadvantages

• Advantages
• Environmental characteristics
• Safety characteristics
• Simplicity
• Controllable performance
• Beneficial use products
• Relative affordability
• Disadvantages
• Low unit cost requires larger quantities

22
Beneficial Use Philosophy

• Soil and sediment are valuable natural resources
• Decontamination is necessary, but not sufficient

• BioGenesis goal decontaminate and beneficially
  use dredged material

010602-04
23
Potential Products Manufactured Soil

• Feasibility has been widely investigated
• USACOE, USEPA, and State studies document the
  capability
• Various qualities and formulas require from 30 to
  40 sediment

010602-12
24
Potential Products Treated Sediment

• Application Island restoration, marsh
  creation/enhancement, shoreline stabilization

25
Potential Products Functional Decorative
Coatings

• Characteristics High impact resistance - 950
  bar, self-leveling, can be molded salt water
  tolerant. Use 60-70 sediment.
• Application Structural repairs above and under
  water

010602-14
26
Potential Products Protective Coatings for Metal

• Characteristics Strong resistance to salt and
  water, can be up to 2 mm thick single component.
  Uses 30 sediment.
• Application Coat metal structures to resist
  corrosion

010602-15
27
Potential Products Bricks Light Aggregate

• Uniform quality of washed sediment is acceptable
  for bricks
• Light aggregate may be feasible to produce at
  about 100oC

Contaminated Sediments CAN Be Treated for
Beneficial Use

• Sediments are highly complex mixtures of organic
  and inorganic material
• Testing shows that chemical and mechanical means
  can clean organic and inorganic contaminants
• BioGenesissm chemicals and full-scale equipment
  implement experimental findings in a practical
  way
• A range of beneficial use products are feasible
  and practical
