Abstract: E-waste is electronic items that have become useless or have reached to the end of their life-span. The maximum e-waste is produced by electronic industry in comparison to vendor and customer. E-waste contains many harmful chemicals which can be absorbed by humans and landfills and floats in the environment. The best solution to control e-waste is re-manufacturing. Re-manufacturing preserves natural resources, saves landfills, reduces greenhouse gas emissions and consequently controls pollution. It also consumes fewer inventories so that it pays less cost. To investigate this e-waste problem and advocating re-manufacturing, we have developed a mathematical model of three compartments viz. manufacturing unit, vendor and customer comprising of remanufacturing at player's ends. To examine the stability of e-waste model, the local and global stability is considered. Threshold and numerical simulation are carried out.

Keywords: e-waste remanufacturing; system of nonlinear differential equation; threshold; local stability; global stability.
