Poly Vinyl Chloride Waste Projection using Life Expectancy of Products

摘要

Purepoly vinyl chloride (PVC) has limited application and mostly uses as its short and long life products. PVC waste projection is complex owing to the diversified life of all its products. This article presents a simple approach for future PVC waste projection using life- expectancy and production data. From past 52-years PVC production data straight line and projection equations were generated and by comparing these with their life- expectancy mathematical equation for future PVC waste is projected. The following equation is proposed under limitation that the initial data collection is always greater than waste projection minus life expectancy year: PVC waste (product based) = [m {(waste projection year- life expectancy) -initial data collection year} + c]
