Other Recycling Cost Estimates

Additional economic evaluation regarding the incremental cost of curbside collection of plastic with other recyclables and MSW are reported by Rankin (1988) and Temple, Barker Sloane (1989). Some of the economic parameters used in these reports (such as tip fee and market prices) are not representative of current condidons. However, the reports concluded that there was a net economic benefit associated with adding plastic bottles to the collection program studied.

Other modules take care of equipment sizing and cost estimation, perform numerical calculations, handle recycle calculation (described in more detail below), optimize, and serve as controllers (executives) for the whole set of modules so that they function in the proper sequence. Figure 5.11 illustrates the information flow in a fiowsheeting package composed of modules. 

DuPont carried out and supported research and development by others focused on conceptual design studies for an NRC licensed fuel recycle complex based on its successful reprocessing experience and lessons learned from that experience and the experience of others. The design studies were completed and reports issued in November 1978. Costs for the 3000 ton/ycar integrated fuel reprocessing/fabrication facility were estimated at 3.7 billion (1978 dollars). Special features ofthis facility design include ... 

In a new process proposed by Kellogg the oxidation of HCI makes use of nitrosyl-sulfuric acid (HNSOs) at 4 bar and 260-320 °C [9], The amount of byproducts diminishes drastically raising the overall yield over 98%. The gaseous emissions are reduced practically to zero. Chlorinated waste from other processes may be incinerated to HCI, and in this way recycled to the manufacturing of VCM. The process is safer because the contact of hydrocarbon mixtures with oxygen is eliminated. A capital cost reduction of 15% may be estimated compared with the oxy-chlorination process. 

Estimated processing costs were deemed acceptable at 6 to 10/kWh of batteries based on a 5,000 (metric) ton per year plant size. This compares favorably to the 40 to 60/kWh incineration cost. The relatively low value of the recovered materials prevents this recycling process from being completely self-supporting. Other more valuable forms of sulfur could be recovered with a modified process, but markets for them may...
