Abstract

Biodiesel is an alternative diesel fuel made from plant oils and animal fats. It is made up of monoalkyl esters that are produced when triglycerides in oil or fat are stimulated to react with simple monohydric alcohol. Transesterification of oils with short-chain alcohols or esterification of fatty acids create biodiesel. HDPE (high-density polyethene) is a plastic resin produced by copolymerizing ethylene with a tiny quantity of another hydrocarbon. HDPE is widely utilized as a primary material in the film, pipe, and container sectors. In this study, HDPE storage tank is used for Biodiesel production. However, HDPE as a storage tank for Biodiesel production has a problem with degradation and a decrease in strength. From the hardness test, B10 under 50 ºC shows the highest decrement value compared with other HDPE samples, and B30 under room temperature shows the lowest decrement value compared with other HDPE samples. From the tensile test, the young modulus of B10-RT is the highest compared with other HDPE samples in week 1, and the young modulus of B10- T50 is the highest compared with other HDPE samples in week 2. High young modulus changes its shapes only slightly.
