Cost Estimation and Profitability Analysis for Alkaline Depolymerization of Poly Ethylene Terephthalate Waste

摘要

Cost estimation and profitability analysis for alkaline hydrolysis of poly ethylene terephthalate waste (PETW) has been undertaken for a batch process. Various cost analysis data are used to evaluate the feasibility of the process for industrial application. The payback period, the rate of return and the break-even point are recorded as four months, 318% and 24%, respectively. It shows good return on investment that promises greater industrial significance.
