The anticipated closure waste quantities are summarized in Tables 4-3 and 4-4. The largest amounts of waste will be metals, halogenated plastics, and concrete. Halogenated... 

The largest volumes of closure wastes will be steel and other metals, activated carbon, halogenated plastic, and concrete. These wastes will for the most part have agent contamination of <1 VSL because they did not come from the areas where neat agent was being processed. It should be possible to ship them to an appropriate TSDF as hazardous waste for further treatment or disposal. 

Ethene bears on its periphery only H atoms. In propene, one H atom is replaced by a methyl group, in styrene by a phenyl ring, in vinyl chloride by a Cl atom. In Fig. 2, this type of substitution is indicated by an X. Monomers with more than one substitution (e.g., polytetrafluorethylene) are used to make high-grade halogenated plastics.

The presence and the relative amounts of non-combustibles, water, detergents, halogenated plastics, corrosive materials, and substances that may present a biological hazard in the waste may all affect the choice of incineration process and off-gas treatment, the overall process flow, and the materials used in the construction. Special attention shall be paid to the presence of spent ion exchange resins and organic liquids in the waste. 

This recommendation does not apply when the incineration system is designed for the processing of a specific waste feed (e.g. ion exchange resin, rubber, halogenated plastics). 

Although there have been relatively few studies of tin additives in non-halogenated plastics, it has been found that tin compounds, including ZHS, ZS and Sn02, when utilized at low addition levels, can significantly improve the flame-retardant and, particularly, the smoke-suppressant properties of halogen-free polymer formulations. 

The Flamtard grades function as both vapor phase and condensed phase flame retardants and smoke suppressants. This dual phase action acts synergistically in halogenated plastic and rubber formulations. For non-halogenated polymers, the addition of Flamtard with a halogen source will improve fire performance and reduce smoke emission.
