To solve the problems due to recycling waste packaging containers , this project aims to calculate recycling rates of waste packaging containers and waste batteries based on the estimated recycling cost model and related survey. The calculated recycling rates of waste packaging containers and batteries could provide helpful information for EPA Fee Rate Review Committee to amend the recycling rates. Moreover, the estimated recycling cost model could be used to estimate recycling cost via various changing price indices and interest rate. Finally, the study results of this project will be used to update and maintain the monitor system of recycling waste packaging containers and batteries. The system linked with cost model can simulate recycling rates for each possible scenario.
