1 Application of BCD Technology in the Czech Republic Dioxin Decontamination Project Spolana a.s. Neratovice

2 Content of Buildings Process plant

3 Content of Buildings Chemical waste

4 Building Decontamination Process Health and Safety Issues Unknown, uncontrolled conditions difficult to quantify dioxin exposure levels Limit high-level exposure to only the workers inside the contaminated buildings. Package the most contaminated material in a manner to prevent re-exposure to operators of the technology.

5 Content of Buildings Stored Chemical waste (130 tonnes in ISO Containers)

6 Decontamination/Demolition

7 Decontamination/Demolition Under pressure air system

8 Decontamination Process

9 Demolition of Buildings

10 Estimated Qty of Materials Waste Description contaminated soil building rubble miscellaneous chemicals timber / cloth dry dust steel glass plastic Tonnes 23,115 8, ,

11 Logistics and Pre-Treatment

12 ITD Facility, Herne,, Germany

13 Indirect Thermal Desorption (ITD) Indirect Desorption under an inert atmosphere Desorbed contaminants are condensed and recovered for BCD Treatment Soil, concrete, and brick Shredded timber/textile blended into soil and treated by the ITD

14 Metal Parts Furnace Technology used for steel parts contaminated with chemical warfare agents Multiple units in operation by the US Army Contaminants desorbed and condensed for treatment by BCD Only approach for complicated shapes

15 10 m 3 Reactor, Mexico

16 Olympic Site, Australia

17 BCD Project, US Navy, Guam

18 Pilot Plant Erection,, Spolana

19 Tent Housing,, Spolana
