What’s in a Name?

• HB1100 – The HB stands for “Heated-Box”. – The first “1” represents the first iteration of the Heated-Box

technology in the market. – The following “100” represents the capacity of each

Heated-Box unit to treat 100 cubic yards of soil or sediment.

• What about “IPTD®”

– This stands for “In Pile Thermal Desorption”, an ex-situ application of our In Situ Thermal Desorption (ISTD) technology. Both make use of the principle of Thermal Conductive Heating (TCH) paired with vapor extraction.

– There different ways to configure IPTD® (details later on), so the HB1100 is but one approach.

Benefits

• Lower price than alternatives: – Traditional on-site thermal desorption (<10,000 cy) – Off-site treatment/incineration

• Eliminates liabilities and risk: – Transporting HW through communities – Manifesting waste – long term ownership

• Proven technology: capable of treating organic contaminants to non-detect levels.

• Sustainable: adheres to ASTM Greener Cleanup Standards

Process Overview

Uses Thermal Conduction Heating (TCH) and vacuum extraction: • TCH is the process of heat flowing from the hot end of a solid object to

the cold end. In soil or rock, heat flows from our heater elements out into the soil by grain-to-grain contact (in soil) and across solid objects (rocks).

7

Heat spreads primarily by conduction

→ uniform heating

Because the process is so robust, it reduces or eliminates pre-treatment material segregation processes, capable of handling soils, sediments, non combustible construction debris, and boulders.

What Contaminants Can TCH Treat?

• Persistent Organic Pollutants (POPs) – polychlorinated biphenyls (PCBs) – pesticides like dichlorodiphenyl-trichloroethane (DDT), endrin,

dieldrin, aldrin, chlordane, toxaphene, heptachlor, mirex, hexachlorobenzene (HCB)

– polychlorinated dibenzo-dioxins and furans (PCDDs/Fs, or simply “dioxins”)

– polycyclic aromatic hydrocarbons (PAHs) such as benzo(a)pyrene

• Any Organic Contaminant – e.g., Chlorinated Volatile Organic Compounds (CVOCs)

• Mercury
