At the end of life (EOL) of an asset or equipment, the failure rate and operating and maintenance costs will increase, so that the equipment needs to be replaced. For control and monitoring equipment, obsolescence is one of the causes of equipment entering the EOL phase. To reduce the growth of WEEE produced by control and monitoring equipment replacement activity, and limitation in capital investment cost, replacement decision making is needed with several sustainability factor consideration. This paper aims to study the addition of sustainability criteria in control and monitoring equipment decision making and implement it in a steel manufacturer industry in Indonesia. Result shown that sustainability can be a consideration in control and monitoring equipment replacement decision making process, but not as high as reliability and equipment lifecycle criteria.
