Disposal process

An Ecoprofile is an assessment of the environmental and resource impacts of a waste disposal process. This paper describes ecoprofiles for six different ways of disposing the plastic fraction in municipal solid waste -two material recycling processes that include separation of the plastic waste, material recycling without separation of the plastic waste, pyrolysis, incineration with heat recovery, and landfill. 17 refs. 

The metal ions are often added as salts of organic compounds, which form chelates. This causes a delayed gelation. Likewise, the components of the gelling agent are pumped down in two stages. Some metal cations cannot be used with brines. On the other hand, brines are often produced from wells, and it is desirable to find uses for them to avoid disposal processes. 

Stripping of electrical and electronic waste appliances must be carried out properly. During the processing of waste appliances (e.g., in shredders), it is essential to avoid that components highly contaminated with hazardous substances end up in fractions that are intended for recycling. It is furthermore necessary to ensure that the disposal of treatment residues (e.g., shredder residues) is not impeded by the presence of hazardous substances. As a rule, components containing particularly hazardous substances are to be removed manually. Future disposal processes, such as pyrolysis, may allow recycling of appliances without prior removal of hazardous substances, in which case it will be possible to do without the disassembly of hazardous components.411... 

Research near Bangalore [35] into the effects of crude disposal processes on the environment and workers found elevated levels of trace elements Cu, Zn, In, Sn, Pb, and Bi in soil near informal recycling shops. Among the workers, hair samples held high levels of Cu, Sb, Bi, Cd, and Ag. 

The Waste Disposal Act is implemented in Taiwan for the recycling of used FLs. As per the Act, the retailers are responsible for the operation of collection centers, whereas authorized recycling facilities are responsible for the lamp recycling/disposal process. 

The approved method for disposal of chemical agent and decontamination of other munition components Is incineration (2 ). Figure 2 presents the functional disposal process selected for this program. 

Starch-BionoUe compound is produced by kneading Bionolle as shown in Sect. 8.6.1 with certain amounts of starch and a plasticizer. All the production processes, except for the production processes for starch and plasticizer newly added as raw materials and those for starch and plasticizer for kneading neat Bionolle, are the same as in Sect. 8.6.1. Product distributions are also the same as in Sect. 8.6.1, since weight and distribution conditions are identical. However, CO2 emission to be accounted for in the disposal process is different from that in Sect. 8.6.1, since raw materials include biomass, i.e., starch. Transportation processes of starch and plasticizer to the Tatsuno Factory are also different. The data for newly added processes and for processes different from those in Sect. 8.6.1 are shown below.

Recommendation 2-5. The Army should determine whether adequate data are available from JACADS to support the efficacy of processing secondary wastes in the metal parts furnace. If not, the Army should determine the additional tests required to confirm a disposal process. A plan based on these results should also be developed for handling and disposing of all secondary wastes from processing the Pueblo stockpile, including demilitarization protective ensemble suits and hoses, spent carbon filter materials, scmbber brine solutions, plant cleaning wastes, and dunnage. 

The TOCDF QRA estimates the risk to the public and workers from accidental releases of chemical agent associated with all activities during storage at DCD and throughout the disposal process at the TOCDF. The HRA, which was conducted by the Utah Division of Solid and Hazardous Waste (Department of Environmental Quality), is a screening analysis to estimate possible off-site human health risks associated with exposure to airborne emissions from the TOCDF under normal and upset conditions. The HRA also estimates risks to wildlife and the environment. 

Monitoring is generally required both for disposal processes and for maintenance activities when workers can potentially be exposed, as well as for emissions and wastes transported off site. SOPCs may be agents or nonagents they may be found in the plant, in outdoor air, in liquid process or effluent streams, on surfaces in the plant, or in solid waste materials. Table 2-1 shows a number of examples of media that may require monitoring.

Finding 3-2. Currently, permit provisions at the various sites require the use of a variety of parameters (including the short-term exposure limit, the short-term limit, the waste control limit, the permit compliance concentration, the vapor screening level, and the Army s X-based notations) for characterizing secondary waste from the chemical agent disposal processes. This inconsistency inhibits clear communication with and understanding by the broader population. 

The disposal of contaminated activated carbon in the JACADS facility used a micronization process followed by incineration. Communications from technical managers involved with this process stated that the micronization and incineration disposal process presented many technical challenges and required a significantly longer investment of time and effort to complete than anticipated.18 No alternative to on-site micronization has been identified, but one is likely to be needed at both TOCDF and UMCDF. 

The synthesis as well as the recycling and disposal of halogenated compounds such as Polyvinylchloride (PVC), flame retardants (for example Tetrabromobisphenol A), y-Hexachlorocydohexane (y-HCH), Hexachlorobenzene (HCB) leads to the formation of byproducts and residues. Polymers, for example, as well as printed circuit boards or shredder residues include problematic substances which, for ecological reasons, cannot be passed on to the environment but have to be supplied to a specific and proper recycling or disposal process. Prior to this background so called "Supercritical Fluids" are of special interest. Supercritical fluids can be used for the synthesis of polymers in an enviromentally friendly way as well as for recycling and disposal processes. 

The work presented here takes as its starting point the need of disposal processes for organically contaminated waste water containing non-biodegradable substances or requiring a particularly high reaction efficiency. 

The examples given above and the work done in the last 10 years on phosphate washing demonstrate that phosphates are very powerful stabilizers of inorganic hazardous contaminants. Phosphate washing is very economical, and once the treated waste is disposed, because phosphates are common fertilizer components, the soil becomes enriched with phosphates. Hence, the entire disposal process is ecologically sound. 

This paper is intended to provide a brief historical overview of the Army s chemical demilitarization program and provide some insight to the types of disposal processes, procedures, and equipment employed. 

For petroleum waste management a deep-well injection disposal process has long been used. This method transfers liquid wastes underground and away from fresh wastewater sources. It is also used to dispose of saltwater in oil fields.
