The goal of this project was to maximize the net present value of the waste stream from recycling copper wire at National Grid’s Investment Recovery Facility. The methods used included lean manufacturing, axiomatic design, and cost benefit analysis. The results showed that the residual “fluff” consisting of rubber and lead could be recovered via electrostatic separator and then sold on the rubber commodity market. The cost analysis suggests that purchasing an electrostatic sorter and selling the treated insulation could result in a cumulative savings of a potential $800,000 over the next ten years.
